commit 1a519dc7a73c977547d8b5108d98c6e769c89f4b upstream.
When running as Xen PV guest, masking MSI-X is a responsibility of the
hypervisor. The guest has no write access to the relevant BAR at all - when
it tries to, it results in a crash like this:
BUG: unable to handle page fault for address: ffffc9004069100c
#PF: supervisor write access in kernel mode
#PF: error_code(0x0003) - permissions violation
RIP: e030:__pci_enable_msix_range.part.0+0x26b/0x5f0
e1000e_set_interrupt_capability+0xbf/0xd0 [e1000e]
e1000_probe+0x41f/0xdb0 [e1000e]
local_pci_probe+0x42/0x80
(...)
The recently introduced function msix_mask_all() does not check the global
variable pci_msi_ignore_mask which is set by XEN PV to bypass the masking
of MSI[-X] interrupts.
Add the check to make this function XEN PV compatible.

commit ac98141d140444fe93e26471d3074c603b70e2ca upstream.
We use the async_delalloc_pages mechanism to make sure that we've
completed our async work before trying to continue our delalloc
flushing. The reason for this is we need to see any ordered extents
that were created by our delalloc flushing. However we're waking up
before we do the submit work, which is before we create the ordered
extents. This is a pretty wide race window where we could potentially
think there are no ordered extents and thus exit shrink_delalloc
prematurely. Fix this by waking us up after we've done the work to
create ordered extents.

commit 4d643b66089591b4769bcdb6fd1bfeff2fe301b8 upstream.
A user space process should not need the CAP_SYS_ADMIN capability set
in order to perform a BLKREPORTZONE ioctl.
Getting the zone report is required in order to get the write pointer.
Neither read() nor write() requires CAP_SYS_ADMIN, so it is reasonable
that a user space process that can read/write from/to the device, also
can get the write pointer. (Since e.g. writes have to be at the write
pointer.)

From: Manivannan Sadhasivam <[email protected]>
commit a89f355e469dcda129c2522be4fdba00c1c74c83 upstream.
In "qmp_cooling_devices_register", the count value is initially
QMP_NUM_COOLING_RESOURCES, which is 2. Based on the initial count value,
the memory for cooling_devs is allocated. Then while calling the
"qmp_cooling_device_add" function, count value is post-incremented for
each child node.
This makes the out of bound access to the cooling_dev array. Fix it by
passing the QMP_NUM_COOLING_RESOURCES definition to devm_kzalloc() and
initializing the count to 0.
While at it, let's also free the memory allocated to cooling_dev if no
cooling device is found in DT and during unroll phase.

commit eb48d154cd0dade56a0e244f0cfa198ea2925ed3 upstream.
The HYP rodata section is currently lumped together with the BSS,
which isn't exactly what is expected (it gets registered with
kmemleak, for example).
Move it away so that it is actually marked RO. As an added
benefit, it isn't registered with kmemleak anymore.

commit 25423731956b3d72bc35d336227c88ada49148e8 upstream.
The UFOE (data compression engine) component needs to be enabled to have
the imgtec gpu driver working. If we don't enable it we see a black screen.
Looks like when we switched to use and array for setting the routing
registers in commit 440147639ac7 ("soc: mediatek: mmsys: Use an array for
setting the routing registers") we missed to add this component in the new
routing table, it was present before that commit, so fix it by adding
this component in the mt8173 routing table.

commit 5e10f9887ed85d4f59266d5c60dd09be96b5dbd4 upstream.
When switching to an 'mm_struct' for the first time following an ASID
rollover, a new ASID may be allocated and assigned to 'mm->context.id'.
This reassignment can happen concurrently with other operations on the
mm, such as unmapping pages and subsequently issuing TLB invalidation.
Consequently, we need to ensure that (a) accesses to 'mm->context.id'
are atomic and (b) all page-table updates made prior to a TLBI using the
old ASID are guaranteed to be visible to CPUs running with the new ASID.
This was found by inspection after reviewing the VMID changes from
Shameer but it looks like a real (yet hard to hit) bug.

From: Josef Bacik <[email protected]>
commit 93c60b17f2b5fca2c5931d7944788d1ef5f25528 upstream.
The preemptive flushing code was added in order to avoid needing to
synchronously wait for ENOSPC flushing to recover space. Once we're
almost full however we can essentially flush constantly. We were using
98% as a threshold to determine if we were simply full, however in
practice this is a really high bar to hit. For example reports of
systems running into this problem had around 94% usage and thus
continued to flush. Fix this by lowering the threshold to 90%, which is
a more sane value, especially for smaller file systems.

commit a680dd72ec336b81511e3bff48efac6dbfa563e7 upstream.
For a request that has a priority level equal to or larger than
IOPRIO_BE_NR, bfq_set_next_ioprio_data() prints a critical warning but
defaults to setting the request new_ioprio field to IOPRIO_BE_NR. This
is not consistent with the warning and the allowed values for priority
levels. Fix this by setting the request new_ioprio field to
IOPRIO_BE_NR - 1, the lowest priority level allowed.

The check mixes pages (vm_pgoff) with bytes (vm_start, vm_end) on one
side of the comparison, and uses resource address (rather than just the
resource size) on the other side of the comparison.
This can allow malicious userspace to easily bypass the boundary check and
map pages that are located outside memory-region reserved by the driver.

Zone management send operations (BLKRESETZONE, BLKOPENZONE, BLKCLOSEZONE
and BLKFINISHZONE) should be allowed under the same permissions as write().
(write() does not require CAP_SYS_ADMIN).
Additionally, other ioctls like BLKSECDISCARD and BLKZEROOUT only check if
the fd was successfully opened with FMODE_WRITE.
(They do not require CAP_SYS_ADMIN).
Currently, zone management send operations require both CAP_SYS_ADMIN
and that the fd was successfully opened with FMODE_WRITE.
Remove the CAP_SYS_ADMIN requirement, so that zone management send
operations match the access control requirement of write(), BLKSECDISCARD
and BLKZEROOUT.

commit 2c197870e4701610ec3b1143808d4e31152caf30 upstream.
When qdio_establish() times out while waiting for the ESTABLISH ccw to
complete, it calls qdio_shutdown() to roll back all of its previous
actions. But at this point the qdio_irq's state is still
QDIO_IRQ_STATE_INACTIVE, so qdio_shutdown() will exit immediately
without doing any actual work.
Which means that eg. the qdio_irq's thinint-indicator stays registered,
and cdev->handler isn't restored to its old value. And since
commit 954d6235be41 ("s390/qdio: make thinint registration symmetric")
the qdio_irq also stays on the tiq_list, so on the next qdio_establish()
we might get a helpful BUG from the list-debugging code:

commit b76d26d69ecc97ebb24aaf40427a13c808a4f488 upstream.
There is no reason to assume that the IRQ rising edge (indicating that
the device start up phase is done) will happen after we request the IRQ.
If the device is already up by the time we request it, the call to
'wait_for_completion_timeout()' will timeout and we will fail the device
probe even though there's nothing wrong.
Fix it by just polling the status register until we get the indication that
the device is up and running. As a side effect of this fix, requesting the
IRQ is also moved to after the setup function.

commit de0534df93474f268486c486ea7e01b44a478026 upstream.
Current error path on failure of validating keepout regions is calling
put_device, eventhough the device is not even registered at that point.
Fix this by adding proper error handling of freeing ida and nvmem.

[ Upstream commit baf8d6899b1e8906dc076ef26cc633e96a8bb0c3 ]
The PWM pins on North Bridge on Armada 37xx can be configured into PWM
or GPIO functions. When in PWM function, each pin can also be configured
to drive low on 0 and tri-state on 1 (LED mode).
The current definitions handle this by declaring two pin groups for each
pin:
- group "pwmN" with functions "pwm" and "gpio"
- group "ledN_od" ("od" for open drain) with functions "led" and "gpio"
This is semantically incorrect. The correct definition for each pin
should be one group with three functions: "pwm", "led" and "gpio".
Change the "pwmN" groups to support "led" function.
Remove "ledN_od" groups. This cannot break backwards compatibility with
older device trees: no device tree uses it since there is no PWM driver
for this SOC yet. Also "ledN_od" groups are not even documented.

From: Mark Rutland <[email protected]>
commit 90268574a3e8a6b883bd802d702a2738577e1006 upstream.
The `compute_indices` and `populate_entries` macros operate on inclusive
bounds, and thus the `map_memory` macro which uses them also operates
on inclusive bounds.
We pass `_end` and `_idmap_text_end` to `map_memory`, but these are
exclusive bounds, and if one of these is sufficiently aligned (as a
result of kernel configuration, physical placement, and KASLR), then:
* In `compute_indices`, the computed `iend` will be in the page/block *after*
the final byte of the intended mapping.
* In `populate_entries`, an unnecessary entry will be created at the end
of each level of table. At the leaf level, this entry will map up to
SWAPPER_BLOCK_SIZE bytes of physical addresses that we did not intend
to map.
As we may map up to SWAPPER_BLOCK_SIZE bytes more than intended, we may
violate the boot protocol and map physical address past the 2MiB-aligned
end address we are permitted to map. As we map these with Normal memory
attributes, this may result in further problems depending on what these
physical addresses correspond to.
The final entry at each level may require an additional table at that
level. As EARLY_ENTRIES() calculates an inclusive bound, we allocate
enough memory for this.
Avoid the extraneous mapping by having map_memory convert the exclusive
end address to an inclusive end address by subtracting one, and do
likewise in EARLY_ENTRIES() when calculating the number of required
tables. For clarity, comments are updated to more clearly document which
boundaries the macros operate on. For consistency with the other
macros, the comments in map_memory are also updated to describe `vstart`
and `vend` as virtual addresses.

[ Upstream commit f4abaa9eebde334045ed6ac4e564d050f1df3013 ]
The power supply states of discharging, charging, full, etc, represent
state of charging, not the capacity level of the battery (for which
we have a separate property). Current HID usage tables to not allow
for expressing charging state of the batteries found in generic
styli, so we should simply assume that the battery is discharging
even if current capacity is at 100% when battery strength reporting
is done via HID interface. In fact, we were doing just that before
commit 581c4484769e.
This change helps UIs to not mis-represent fully charged batteries in
styli as being charging/topping-off.

commit 87df7fb922d18e96992aa5e824aa34b2065fef59 upstream.
When new work is added, io_wqe_enqueue() checks if we need to wake or
create a new worker. But that check is done outside the lock that
otherwise synchronizes us with a worker going to sleep, so we can end
up in the following situation:
CPU0 CPU1
lock
insert work
unlock
atomic_read(nr_running) != 0
lock
atomic_dec(nr_running)
no wakeup needed
Hold the wqe lock around the "need to wakeup" check. Then we can also get
rid of the temporary work_flags variable, as we know the work will remain
valid as long as we hold the lock.

commit a8bd29bd49c4156ea0ec5a97812333e2aeef44e7 upstream.
The pciconfig_read() syscall reads PCI configuration space using
hardware-dependent config accessors.
If the read fails on PCI, most accessors don't return an error; they
pretend the read was successful and got ~0 data from the device, so the
syscall returns success with ~0 data in the buffer.
When the accessor does return an error, pciconfig_read() normally fills the
user's buffer with ~0 and returns an error in errno. But after
e4585da22ad0 ("pci syscall.c: Switch to refcounting API"), we don't fill
the buffer with ~0 for the EPERM "user lacks CAP_SYS_ADMIN" error.
Userspace may rely on the ~0 data to detect errors, but after e4585da22ad0,
that would not detect CAP_SYS_ADMIN errors.
Restore the original behaviour of filling the buffer with ~0 when the
CAP_SYS_ADMIN check fails.

commit 64f160e19e9264a7f6d89c516baae1473b6f8359 upstream.
In commit 6df6ba974a55 ("PCI: aardvark: Remove PCIe outbound window
configuration") was removed aardvark PCIe outbound window configuration and
commit description said that was recommended solution by HW designers.
But that commit completely removed support for configuring PCIe IO
resources without removing PCIe IO 'ranges' from DTS files. After that
commit PCIe IO space started to be treated as PCIe MEM space and accessing
it just caused kernel crash.
Moreover implementation of PCIe outbound windows prior that commit was
incorrect. It completely ignored offset between CPU address and PCIe bus
address and expected that in DTS is CPU address always same as PCIe bus
address without doing any checks. Also it completely ignored size of every
PCIe resource specified in 'ranges' DTS property and expected that every
PCIe resource has size 128 MB (also for PCIe IO range). Again without any
check. Apparently none of PCIe resource has in DTS specified size of 128
MB. So it was completely broken and thanks to how aardvark mask works,
configuration was completely ignored.
This patch reverts back support for PCIe outbound window configuration but
implementation is a new without issues mentioned above. PCIe outbound
window is required when DTS specify in 'ranges' property non-zero offset
between CPU and PCIe address space. To address recommendation by HW
designers as specified in commit description of 6df6ba974a55, set default
outbound parameters as PCIe MEM access without translation and therefore
for this PCIe 'ranges' it is not needed to configure PCIe outbound window.
For PCIe IO space is needed to configure aardvark PCIe outbound window.
This patch fixes kernel crash when trying to access PCIe IO space.

it directly. Otherwise we would get a call trace like this:

From: Evan Wang <[email protected]>
commit fcb461e2bc8b83b7eaca20cb2221e8b940f2189c upstream.
There is an issue that when PCIe switch is connected to an Armada 3700
board, there will be lots of warnings about PIO errors when reading the
config space. According to Aardvark PIO read and write sequence in HW
specification, the current way to check PIO status has the following
issues:
1) For PIO read operation, it reports the error message, which should be
avoided according to HW specification.
2) For PIO read and write operations, it only checks PIO operation complete
status, which is not enough, and error status should also be checked.
This patch aligns the code with Aardvark PIO read and write sequence in HW
specification on PIO status check and fix the warnings when reading config
space.

commit f985911b7bc75d5c98ed24d8aaa8b94c590f7c6a upstream.
Hit kernel warning like this, it can be reproduced by verifying 256
bytes datafile by keyctl command, run script:
RAWDATA=rawdata
SIGDATA=sigdata
modprobe pkcs8_key_parser
rm -rf *.der *.pem *.pfx
rm -rf $RAWDATA
dd if=/dev/random of=$RAWDATA bs=256 count=1
openssl req -nodes -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem \
-subj "/C=CN/ST=GD/L=SZ/O=vihoo/OU=dev/CN=xx.com/[email protected]"
KEY_ID=`openssl pkcs8 -in key.pem -topk8 -nocrypt -outform DER | keyctl \
padd asymmetric 123 @s`
keyctl pkey_sign $KEY_ID 0 $RAWDATA enc=pkcs1 hash=sha1 > $SIGDATA
keyctl pkey_verify $KEY_ID 0 $RAWDATA $SIGDATA enc=pkcs1 hash=sha1
Then the kernel reports:
WARNING: CPU: 5 PID: 344556 at crypto/rsa-pkcs1pad.c:540
pkcs1pad_verify+0x160/0x190
...
Call Trace:

entry_SYSCALL_64_after_hwframe+0x44/0xae
The reason of this issue, in function 'asymmetric_key_verify_signature':
'.digest_size(u8) = params->in_len(u32)' leads overflow of an u8 value,
so use u32 instead of u8 for digest_size field. And reorder struct
public_key_signature, it saves 8 bytes on a 64-bit machine.

commit a30dc6cf0dc51419021550152e435736aaef8799 upstream.
I got a NULL pointer dereference report when doing fuzz test:

When a queue pair is created by the following call, it will not
register the user memory if the page_store is NULL, and the
entry->state will be set to VMCIQPB_CREATED_NO_MEM.
vmci_host_unlocked_ioctl
vmci_host_do_alloc_queuepair
vmci_qp_broker_alloc
qp_broker_alloc
qp_broker_create // set entry->state = VMCIQPB_CREATED_NO_MEM;
When unmapping this queue pair, qp_host_unregister_user_memory() will
be called to unregister the non-existent user memory, which will
result in a null pointer reference. It will also change
VMCIQPB_CREATED_NO_MEM to VMCIQPB_CREATED_MEM, which should not be
present in this operation.
Only when the qp broker has mem, it can unregister the user
memory when unmapping the qp broker.
Only when the qp broker has no mem, it can register the user
memory when mapping the qp broker.

commit 1a10d7fdb6d0e235e9d230916244cc2769d3f170 upstream.
As warned by smatch:

drivers/media/usb/uvc/uvc_v4l2.c:943 uvc_ioctl_s_input() error: doing dma on the stack (&i)
those two functions call uvc_query_ctrl passing a pointer to
a data at the DMA stack. those are used to send URBs via
usb_control_msg(). Using DMA stack is not supported and should
not work anymore on modern Linux versions.
So, use a kmalloc'ed buffer.

commit de0a01f5296651d3a539f2d23d0db8f359483696 upstream.
Enable PCIe reference clock. There is no remove function that's why
this should be enough for simple operation.
Normally this clock is enabled by default by firmware but there are
usecases where this clock should be enabled by driver itself.
It is also good that PCIe clock is recorded in a clock framework.

[ Upstream commit 62004871e1fa7f9a60797595c03477af5b5ec36f ]
It is possible for the primary IPoIB network device associated with any
RDMA device to fail to join certain multicast groups preventing IPv6
neighbor discovery and possibly other network ULPs from working
correctly. The IPv4 broadcast group is not affected as the IPoIB network
device handles joining that multicast group directly.
This is because the primary IPoIB network device uses the pkey at ndex 0
in the associated RDMA device's pkey table. Anytime the pkey value of
index 0 changes, the primary IPoIB network device automatically modifies
it's broadcast address (i.e. /sys/class/net/[ib0]/broadcast), since the
broadcast address includes the pkey value, and then bounces carrier. This
includes initial pkey assignment, such as when the pkey at index 0
transitions from the opa default of invalid (0x0000) to some value such as
the OPA default pkey for Virtual Fabric 0: 0x8001 or when the fabric
manager is restarted with a configuration change causing the pkey at index
0 to change. Many network ULPs are not sensitive to the carrier bounce and
are not expecting the broadcast address to change including the linux IPv6
stack. This problem does not affect IPoIB child network devices as their
pkey value is constant for all time.
To mitigate this issue, change the default pkey in at index 0 to 0x8001 to
cover the predominant case and avoid issues as ipoib comes up and the FM
sweeps.
At some point, ipoib multicast support should automatically fix
non-broadcast addresses as it does with the primary broadcast address.

[ Upstream commit d4bf15a7ce172d186d400d606adf4f34a59130d6 ]
I recently found a case where de->name_len is 0 in f2fs_fill_dentries()
easily reproduced, and finally set the fsck flag.
Thread A Thread B
- f2fs_readdir
- f2fs_read_inline_dir
- ctx->pos = d.max
- f2fs_add_dentry
- f2fs_add_inline_entry
- do_convert_inline_dir
- f2fs_add_regular_entry
- f2fs_readdir
- f2fs_fill_dentries
- set_sbi_flag(sbi, SBI_NEED_FSCK)
Process A opens the folder, and has been reading without closing it.
During this period, Process B created a file under the folder (occupying
multiple f2fs_dir_entry, exceeding the d.max of the inline dir). After
creation, process A uses the d.max of inline dir to read it again, and
it will read that de->name_len is 0.
And Chao pointed out that w/o inline conversion, the race condition still
can happen as below:
dir_entry1: A
dir_entry2: B
dir_entry3: C
free slot: _
ctx->pos: ^
Thread A is traversing directory,
ctx-pos moves to below position after readdir() by thread A:
AAAABBBB___
^
Then thread B delete dir_entry2, and create dir_entry3.
Thread A calls readdir() to lookup dirents starting from middle
of new dirent slots as below:
AAAACCCCCC_
^
In these scenarios, the file system is not damaged, and it's hard to
avoid it. But we can bypass tagging FSCK flag if:
a) bit_pos (:= ctx->pos % d->max) is non-zero and
b) before bit_pos moves to first valid dir_entry.

[ Upstream commit 173735c346c412d9f084825ecb04f24ada0e2986 ]
Due to link order, dma_debug_init is called before debugfs has a chance
to initialize (via debugfs_init which also happens in the core initcall
stage), so the directories for dma-debug are never created.
Decouple dma_debug_fs_init from dma_debug_init and defer its init until
core_initcall_sync (after debugfs has been initialized) while letting
dma-debug initialization occur as soon as possible to catch any early
mappings, as suggested in [1].

[ Upstream commit 35b72573e977ed6b18b094136a4fa3e0ffb13603 ]
The current hash algorithm used for hashing cookie keys is really bad,
producing almost no dispersion (after a test kernel build, ~30000 files
were split over just 18 out of the 32768 hash buckets).
Borrow the full_name_hash() hash function into fscache to do the hashing
for cookie keys and, in the future, volume keys.
I don't want to use full_name_hash() as-is because I want the hash value to
be consistent across arches and over time as the hash value produced may
get used on disk.
I can also optimise parts of it away as the key will always be a padded
array of aligned 32-bit words.

The rk3036/rk3328 pll types were converted to checking the lock status
via the internal register in january 2020, so don't need the grf
reference since then.
But it was forgotten to remove grf check when deciding between the
pll rate ops (read-only vs. read-write), so a clock driver without
the needed grf reference might've been put into the read-only mode
just because the grf reference was missing.
This affected the rk356x that needs to reclock certain plls at boot.
Fix this by removing the check for the grf for selecting the utilized
operations.

[ Upstream commit b8b928030332a0ca16d42433eb2c3085600d8704 ]
lscpu() uses core_siblings to list the number of sockets in the
system. core_siblings is set using topology_core_cpumask.
While optimizing the powerpc bootup path, Commit 4ca234a9cbd7
("powerpc/smp: Stop updating cpu_core_mask"). it was found that
updating cpu_core_mask() ended up taking a lot of time. It was thought
that on Powerpc, cpu_core_mask() would always be same as
cpu_cpu_mask() i.e number of sockets will always be equal to number of
nodes. As an optimization, cpu_core_mask() was made a snapshot of
cpu_cpu_mask().
However that was found to be false with PowerPc KVM guests, where each
node could have more than one socket. So with Commit c47f892d7aa6
("powerpc/smp: Reintroduce cpu_core_mask"), cpu_core_mask was updated
based on chip_id but in an optimized way using some mask manipulations
and chip_id caching.
However on non-PowerNV and non-pseries KVM guests (i.e not
implementing cpu_to_chip_id(), continued to use a copy of
cpu_cpu_mask().
There are two issues that were noticed on such systems
1. lscpu would report one extra socket.
On a IBM,9009-42A (aka zz system) which has only 2 chips/ sockets/
nodes, lscpu would report
Architecture: ppc64le
Byte Order: Little Endian
CPU(s): 160
On-line CPU(s) list: 0-159
Thread(s) per core: 8
Core(s) per socket: 6
Socket(s): 3 <--------------
NUMA node(s): 2
Model: 2.2 (pvr 004e 0202)
Model name: POWER9 (architected), altivec supported
Hypervisor vendor: pHyp
Virtualization type: para
L1d cache: 32K
L1i cache: 32K
L2 cache: 512K
L3 cache: 10240K
NUMA node0 CPU(s): 0-79
NUMA node1 CPU(s): 80-159
2. Currently cpu_cpu_mask is updated when a core is
added/removed. However its not updated when smt mode switching or on
CPUs are explicitly offlined. However all other percpu masks are
updated to ensure only active/online CPUs are in the masks.
This results in build_sched_domain traces since there will be CPUs in
cpu_cpu_mask() but those CPUs are not present in SMT / CACHE / MC /
NUMA domains. A loop of threads running smt mode switching and core
add/remove will soon show this trace.
Hence cpu_cpu_mask has to be update at smt mode switch.
This will have impact on cpu_core_mask(). cpu_core_mask() is a
snapshot of cpu_cpu_mask. Different CPUs within the same socket will
end up having different cpu_core_masks since they are snapshots at
different points of time. This means when lscpu will start reporting
many more sockets than the actual number of sockets/ nodes / chips.
Different ways to handle this problem:
A. Update the snapshot aka cpu_core_mask for all CPUs whenever
cpu_cpu_mask is updated. This would a non-optimal solution.
B. Instead of a cpumask_var_t, make cpu_core_map a cpumask pointer
pointing to cpu_cpu_mask. However percpu cpumask pointer is frowned
upon and we need a clean way to handle PowerPc KVM guest which is
not a snapshot.
C. Update cpu_core_masks all PowerPc systems like in PowerPc KVM
guests using mask manipulations. This approach is relatively simple
and unifies with the existing code.
D. On top of 3, we could also resurrect get_physical_package_id which
could return a nid for the said CPU. However this is not needed at this
time.
Option C is the preferred approach for now.
While this is somewhat a revert of Commit 4ca234a9cbd7 ("powerpc/smp:
Stop updating cpu_core_mask").
1. Plain revert has some conflicts
2. For chip_id == -1, the cpu_core_mask is made identical to
cpu_cpu_mask, unlike previously where cpu_core_mask was set to a core
if chip_id doesn't exist.
This goes by the principle that if chip_id is not exposed, then
sockets / chip / node share the same set of CPUs.
With the fix, lscpu o/p would be

From: Dan Carpenter <[email protected]>
[ Upstream commit ccc89737aa6b9f248cf1623014038beb6c2b7f56 ]
This driver has some left over "return 1" on failure style code mixed with
"return negative error codes" style code. The caller doesn't care so we
should just convert everything to return negative error codes.
Then there was a problem that there were two variables used to store error
codes which just resulted in confusion. If qedf_alloc_bdq() returned a
negative error code, we accidentally returned success instead of
propagating the error code. So get rid of the "rc" variable and use
"status" every where.
Also remove the "status = 0" initialization so that these sorts of bugs
will be detected by the compiler in the future.

[ Upstream commit f99fa50880f5300fbbb3c0754ddc7f8738d24fe7 ]
The xprtrdma client code currently relies on the task that initiated the
connect to hold the XPRT_LOCK for the duration of the connection
attempt. If the task is woken early, due to some other event, then that
lock could get released early.
Avoid races by using the same mechanism that the socket code uses of
transferring lock ownership to the RDMA connect worker itself. That
frees us to call rpcrdma_xprt_disconnect() directly since we're now
guaranteed exclusion w.r.t. other callers.

[ Upstream commit 22e5fe2a2a279d9a6fcbdfb4dffe73821bef1c90 ]
userfaultfd assumes that the enabled features are set once and never
changed after UFFDIO_API ioctl succeeded.
However, currently, UFFDIO_API can be called concurrently from two
different threads, succeed on both threads and leave userfaultfd's
features in non-deterministic state. Theoretically, other uffd operations
(ioctl's and page-faults) can be dispatched while adversely affected by
such changes of features.
Moreover, the writes to ctx->state and ctx->features are not ordered,
which can - theoretically, again - let userfaultfd_ioctl() think that
userfaultfd API completed, while the features are still not initialized.
To avoid races, it is arguably best to get rid of ctx->state. Since there
are only 2 states, record the API initialization in ctx->features as the
uppermost bit and remove ctx->state.

[ Upstream commit 462ba66198a4a8ea996028915af10a698086e302 ]
Commit c49c33637802 ("HID: support for initialization of some Thrustmaster
wheels") messed up the Makefile and quirks during the refactoring of this
commit.
Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:
HID_TMINIT
Referencing files: drivers/hid/Makefile, drivers/hid/hid-quirks.c
Following the discussion (see Link), CONFIG_HID_THRUSTMASTER is the
intended config for CONFIG_HID_TMINIT and the file hid-tminit.c was
actually added as hid-thrustmaster.c.
So, clean up Makefile and adapt quirks to that refactoring.

[ Upstream commit 4dbe57d46d54a847875fa33e7d05877bb341585e ]
This function had some left over code that returned 1 on error instead
negative error codes. Convert everything to use negative error codes. The
caller treats all non-zero returns the same so this does not affect run
time.
A couple places set "rc" instead of "status" so those error paths ended up
returning success by mistake. Get rid of the "rc" variable and use
"status" everywhere.
Remove the bogus "status = 0" initialization, as a future proofing measure
so the compiler will warn about uninitialized error codes.

[ Upstream commit b43e2ec03b0de040d536591713ea9c875ff34ba9 ]
Replace vkms' prepare_fb and cleanup_fb functions with the generic
code for shadow-buffered planes. No functional changes.
This change also fixes a problem where IGT kms_flip tests would
create a segmentation fault within vkms. The driver's prepare_fb
function did not report an error if a BO's vmap operation failed.
The kernel later tried to operate on the non-mapped memory areas.
The shared shadow-plane helpers handle errors correctly, so that
the driver now avoids the segmantation fault.
v2:
* include paragraph about IGT tests in commit message (Melissa)

In below path, it will return ENOENT if filesystem is shutdown:
- f2fs_map_blocks
- f2fs_get_dnode_of_data
- f2fs_get_node_page
- __get_node_page
- read_node_page
- is_sbi_flag_set(sbi, SBI_IS_SHUTDOWN)
return -ENOENT
- force return value from ENOENT to 0
It should be fine for read case, since it indicates a hole condition,
and caller could use .m_next_pgofs to skip the hole and continue the
lookup.
However it may cause confusing for write case, since leaving a hole
there, and said nothing was wrong doesn't help.
There is at least one case from dax_iomap_actor() will complain that,
so fix this in prior to supporting dax in f2fs.

[ Upstream commit 14858dcc3b3587f4bb5c48e130ee7d68fc2b0a29 ]
Updating the current_state field of struct pci_dev the way it is done
in pci_enable_device_flags() before calling do_pci_enable_device() may
not work. For example, if the given PCI device depends on an ACPI
power resource whose _STA method initially returns 0 ("off"), but the
config space of the PCI device is accessible and the power state
retrieved from the PCI_PM_CTRL register is D0, the current_state
field in the struct pci_dev representing that device will get out of
sync with the power.state of its ACPI companion object and that will
lead to power management issues going forward.
To avoid such issues, make pci_enable_device_flags() call
pci_update_current_state() which takes ACPI device power management
into account, if present, to retrieve the current power state of the
device.

2.30.2
From: Martynas Pumputis <[email protected]>
[ Upstream commit 97eb31384af943d6b97eb5947262cee4ef25cb87 ]
When loading a BPF program with a pinned map, the loader checks whether
the pinned map can be reused, i.e. their properties match. To derive
such of the pinned map, the loader invokes BPF_OBJ_GET_INFO_BY_FD and
then does the comparison.
Unfortunately, on < 4.12 kernels the BPF_OBJ_GET_INFO_BY_FD is not
available, so loading the program fails with the following error:
libbpf: failed to get map info for map FD 5: Invalid argument
libbpf: couldn't reuse pinned map at
'/sys/fs/bpf/tc/globals/cilium_call_policy': parameter
mismatch"
libbpf: map 'cilium_call_policy': error reusing pinned map
libbpf: map 'cilium_call_policy': failed to create:
Invalid argument(-22)
libbpf: failed to load object 'bpf_overlay.o'
To fix this, fallback to derivation of the map properties via
/proc/$PID/fdinfo/$MAP_FD if BPF_OBJ_GET_INFO_BY_FD fails with EINVAL,
which can be used as an indicator that the kernel doesn't support
the latter.

From: Zheyu Ma <[email protected]>
[ Upstream commit 1520b4b7ba964f8eec2e7dd14c571d50de3e5191 ]
The userspace program could pass any values to the driver through
ioctl() interface. if the driver doesn't check the value of 'pixclock',
it may cause divide error because the value of 'lineclock' and
'frameclock' will be zero.
Fix this by checking whether 'pixclock' is zero in kyrofb_check_var().
The following log reveals it:

From: Johan Almbladh <[email protected]>
[ Upstream commit 2b7e9f25e590726cca76700ebdb10e92a7a72ca1 ]
Each test case can have a set of sub-tests, where each sub-test can
run the cBPF/eBPF test snippet with its own data_size and expected
result. Before, the end of the sub-test array was indicated by both
data_size and result being zero. However, most or all of the internal
eBPF tests has a data_size of zero already. When such a test also had
an expected value of zero, the test was never run but reported as
PASS anyway.
Now the test runner always runs the first sub-test, regardless of the
data_size and result values. The sub-test array zero-termination only
applies for any additional sub-tests.
There are other ways fix it of course, but this solution at least
removes the surprise of eBPF tests with a zero result always succeeding.

From: Geert Uytterhoeven <[email protected]>
[ Upstream commit 47956bc86ee4e8530cac386a04f62a6095f7afbe ]
As nwl_dsi.lanes is u32, and NSEC_PER_SEC is 1000000000L, the second
multiplication in
dsi->lanes * 8 * NSEC_PER_SEC
will overflow on a 32-bit platform. Fix this by making the constant
unsigned long long, forcing 64-bit arithmetic.
As iMX8 is arm64, this driver is currently used on 64-bit platforms
only, where long is 64-bit, so this cannot happen. But the issue will
start to happen when the driver is reused for a 32-bit SoC (e.g.
i.MX7ULP), or when code is copied for a new driver.

The return type of the function is bool and while NULL do evaluate to
false it's not very nice, fix this by explicitly returning false. There
is no functional change.

2.30.2
From: Arnd Bergmann <[email protected]>
[ Upstream commit dd98d2895de6485c884a9cb42de69fed02826fa4 ]
The ethtool compat ioctl handling is hidden away in net/socket.c,
which introduces a couple of minor oddities:
- The implementation may end up diverging, as seen in the RXNFC
extension in commit 84a1d9c48200 ("net: ethtool: extend RXNFC
API to support RSS spreading of filter matches") that does not work
in compat mode.
- Most architectures do not need the compat handling at all
because u64 and compat_u64 have the same alignment.
- On x86, the conversion is done for both x32 and i386 user space,
but it's actually wrong to do it for x32 and cannot work there.
- On 32-bit Arm, it never worked for compat oabi user space, since
that needs to do the same conversion but does not.
- It would be nice to get rid of both compat_alloc_user_space()
and copy_in_user() throughout the kernel.
None of these actually seems to be a serious problem that real
users are likely to encounter, but fixing all of them actually
leads to code that is both shorter and more readable.

ioctl() interface. If the driver doesn't check the value of 'pixclock',
it may cause divide error.
Fix this by checking whether 'pixclock' is zero first.

From: Juhee Kang <[email protected]>
[ Upstream commit 7d07006f05922b95518be403f08ef8437b67aa32 ]
The current behavior of 'tracex7' doesn't consist with other bpf samples
tracex{1..6}. Other samples do not require any argument to run with, but
tracex7 should be run with btrfs device argument. (it should be executed
with test_override_return.sh)
Currently, tracex7 doesn't have any description about how to run this
program and raises an unexpected error. And this result might be
confusing since users might not have a hunch about how to run this
program.
// Current behavior
# ./tracex7
sh: 1: Syntax error: word unexpected (expecting ")")
// Fixed behavior
# ./tracex7
ERROR: Run with the btrfs device argument!
In order to fix this error, this commit adds logic to report a message
and exit when running this program with a missing argument.
Additionally in test_override_return.sh, there is a problem with
multiple directory(tmpmnt) creation. So in this commit adds a line with
removing the directory with every execution.

2.30.2
From: Niklas Schnelle <[email protected]>
[ Upstream commit 3322ba0d7bea1e24ae464418626f6a15b69533ab ]
Kernel support for the newer PCI mio instructions can be toggled off
with the pci=nomio command line option which needs to integrate with
common code PCI option parsing. However this option then toggles static
branches which can't be toggled yet in an early_param() call.
Thus commit 9964f396f1d0 ("s390: fix setting of mio addressing control")
moved toggling the static branches to the PCI init routine.
With this setup however we can't check for mio support outside the PCI
code during early boot, i.e. before switching the static branches, which
we need to be able to export this as an ELF HWCAP.
Improve on this by turning mio availability into a machine flag that
gets initially set based on CONFIG_PCI and the facility bit and gets
toggled off if pci=nomio is found during PCI option parsing allowing
simple access to this machine flag after early init.

Last change to device managed APIs cleaned up error path to simple phy_exit()

is not a problem, but rather logical misconception: no need to free resource

These for-loops should test against v4l2_dv_timings_presets[i].bt.width,
not if i < v4l2_dv_timings_presets[i].bt.width. Luckily nothing ever broke,
since the smallest width is still a lot higher than the total number of
presets, but it is wrong.
The last item in the presets array is all 0, so the for-loop must stop
when it reaches that sentinel.

[ Upstream commit d7aff291d069c4418285f3c8ee27b0ff67ce5998 ]
Oxford Semiconductor 950 serial port devices have a 128-byte FIFO and in
the enhanced (650) mode, which we select in `autoconfig_has_efr' with
the ECB bit set in the EFR register, they support the receive interrupt
trigger level selectable with FCR bits 7:6 from the set of 16, 32, 112,
120. This applies to the original OX16C950 discrete UART[1] as well as
950 cores embedded into more complex devices.
For these devices we set the default to 112, which sets an excessively
high level of 112 or 7/8 of the FIFO capacity, unlike with other port
types where we choose at most 1/2 of their respective FIFO capacities.
Additionally we don't make the trigger level configurable. Consequently
frequent input overruns happen with high bit rates where hardware flow
control cannot be used (e.g. terminal applications) even with otherwise
highly-performant systems.
Lower the default receive interrupt trigger level to 32 then, and make
it configurable. Document the trigger levels along with other port
types, including the set of 16, 32, 64, 112 for the transmit interrupt
as well[2].

Semiconductor, Inc., DS-0031, Sep 05, Table 10: "Receiver Trigger
Levels", p. 22

When the system shuts down or warm reboots, the display may be active,
with the hardware accessing system memory. Upon reboot, the DDR will not
be accessible, which may cause issues.
Implement the platform_driver .shutdown() operation and shut down the
display to fix this.

When the stream fails to start, the first two buffers in the queue have
been moved to the active_vb2_buf array and are returned to vb2 by
imx7_csi_dma_unsetup_vb2_buf(). The function is called with the buffer
state set to VB2_BUF_STATE_ERROR unconditionally, which is correct when
stopping the stream, but not when the start operation fails. In that
case, the state should be set to VB2_BUF_STATE_QUEUED. Fix it.

and while it would be very difficult to get them to wrap as a negative

checking if the RPA has not been set (BDADDR_ANY), furthermore it was
clearing HCI_RPA_EXPIRED before the command completes and the RPA is
actually programmed which in case of failure would leave the expired
RPA still set.
Since advertising instance have a similar problem the clearing of
HCI_RPA_EXPIRED has been moved to hci_event.c after checking the random
address is in fact the hdev->rap and then proceed to set the expire

From: Desmond Cheong Zhi Xi <[email protected]>
[ Upstream commit ba316be1b6a00db7126ed9a39f9bee434a508043 ]
struct sock.sk_timer should be used as a sock cleanup timer. However,
SCO uses it to implement sock timeouts.
This causes issues because struct sock.sk_timer's callback is run in
an IRQ context, and the timer callback function sco_sock_timeout takes
a spin lock on the socket. However, other functions such as
sco_conn_del and sco_conn_ready take the spin lock with interrupts
enabled.
This inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} lock usage could
lead to deadlocks as reported by Syzbot [1]:
CPU0
----
lock(slock-AF_BLUETOOTH-BTPROTO_SCO);
<Interrupt>
lock(slock-AF_BLUETOOTH-BTPROTO_SCO);
To fix this, we use delayed work to implement SCO sock timouts
instead. This allows us to avoid taking the spin lock on the socket in
an IRQ context, and corrects the misuse of struct sock.sk_timer.
As a note, cancel_delayed_work is used instead of
cancel_delayed_work_sync in sco_sock_set_timer and
sco_sock_clear_timer to avoid a deadlock. In the future, the call to
bh_lock_sock inside sco_sock_timeout should be changed to lock_sock to
synchronize with other functions using lock_sock. However, since
sco_sock_set_timer and sco_sock_clear_timer are sometimes called under
the locked socket (in sco_connect and __sco_sock_close),
cancel_delayed_work_sync might cause them to sleep until an
sco_sock_timeout that has started finishes running. But
sco_sock_timeout would also sleep until it can grab the lock_sock.
Using cancel_delayed_work is fine because sco_sock_timeout does not
change from run to run, hence there is no functional difference
between:
1. waiting for a timeout to finish running before scheduling another
timeout
2. scheduling another timeout while a timeout is running.

The alloc_tty_driver failure is handled gracefully in hvsi_init. But
tty_register_driver is not. panic is called if that one fails.
So handle the failure of tty_register_driver gracefully too. This will
keep at least the console functional as it was enabled earlier by
console_initcall in hvsi_console_init. Instead of shooting down the
whole system.
This means, we disable interrupts and restore hvsi_wait back to
poll_for_state().

[ Upstream commit 23411c720052ad860b3e579ee4873511e367130a ]
While alloc_tty_driver failure in rs_init would mean we have much bigger
problem, there is no reason to panic when tty_register_driver fails
there. It can fail for various reasons.
So handle the failure gracefully. Actually handle them both while at it.
This will make at least the console functional as it was enabled earlier
by console_initcall in iss_console_init. Instead of shooting down the
whole system.
We move tty_port_init() after alloc_tty_driver(), so that we don't need
to destroy the port in case the latter function fails.

[ Upstream commit 0fd75f5760b6a7a7f35dff46a6cdc4f6d1a86ee8 ]
Three interconnects are defined for IPA version 4.9, but there
should only be two. They should also use names that match what's
used for other platforms (and specified in the Device Tree binding).

In error handling branch "if (WARN_ON(node == NUMA_NO_NODE))", the
previously allocated memories are not released. Doing this before
allocating memory eliminates memory leaks.
tj: Note that the condition only occurs when the arch code is pretty broken
and the WARN_ON might as well be BUG_ON().

[ Upstream commit 1fe0e1fa3209ad8e9124147775bd27b1d9f04bd4 ]
Handle optional overrun-throttle-ms property as done for 8250_fsl in commit
6d7f677a2afa ("serial: 8250: Rate limit serial port rx interrupts during
input overruns"). This can be used to rate limit the UART interrupts on
noisy lines that end up producing messages like the following:
ttyS ttyS2: 4 input overrun(s)
At least on droid4, the multiplexed USB and UART port is left to UART mode
by the bootloader for a debug console, and if a USB charger is connected
on boot, we get noise on the UART until the PMIC related drivers for PHY
and charger are loaded.
With this patch and overrun-throttle-ms = <500> we avoid the extra rx

The 'required-opps' property is considered optional, hence remove
the pr_err() in of_parse_required_opp() when we find the property is
missing.
While at it, also fix the return value of
of_get_required_opp_performance_state() when of_parse_required_opp()
fails, return a -ENODEV instead of the -EINVAL.

2.30.2
From: Martynas Pumputis <[email protected]>
[ Upstream commit 043c5bb3c4f43670ab4fea0b847373ab42d25f3e ]
When loading in parallel multiple programs which use the same to-be
pinned map, it is possible that two instances of the loader will call
bpf_object__create_maps() at the same time. If the map doesn't exist
when both instances call bpf_object__reuse_map(), then one of the
instances will fail with EEXIST when calling bpf_map__pin().
Fix the race by retrying reusing a map if bpf_map__pin() returns
EEXIST. The fix is similar to the one in iproute2: e4c4685fd6e4 ("bpf:
Fix race condition with map pinning").
Before retrying the pinning, we don't do any special cleaning of an
internal map state. The closer code inspection revealed that it's not
required:
- bpf_object__create_map(): map->inner_map is destroyed after a
successful call, map->fd is closed if pinning fails.
- bpf_object__populate_internal_map(): created map elements is
destroyed upon close(map->fd).
- init_map_slots(): slots are freed after their initialization.

In tb_switch_default_link_ports(), while linking of ports,
only odd-numbered ports (1,3,5..) are considered and even-numbered
ports are not considered.
AMD host router has lane adapters at 2 and 3 and link ports at adapter 2
is not considered due to which lane bonding gets disabled.
Hence added a fix such that all ports are considered during
linking of ports.

[ Upstream commit 4367355dd90942a71641c98c40c74589c9bddf90 ]
When compiling with clang in certain configurations, an objtool warning
appears:
drivers/net/ethernet/stmicro/stmmac/dwmac-ipq806x.o: warning: objtool:
ipq806x_gmac_probe() falls through to next function phy_modes()
This happens because the unreachable annotation in the third switch
statement is not eliminated. The compiler should know that the first
default case would prevent the second and third from being reached as
the comment notes but sanitizer options can make it harder for the
compiler to reason this out.
Help the compiler out by eliminating the unreachable() annotation and
unifying the default case error handling so that there is no objtool
warning, the meaning of the code stays the same, and there is less
duplication.

other info that might help us debug this:
Chain exists of:
sk_lock-AF_BLUETOOTH-BTPROTO_SCO --> &hdev->lock --> hci_cb_list_lock
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(hci_cb_list_lock);
lock(&hdev->lock);
lock(hci_cb_list_lock);
lock(sk_lock-AF_BLUETOOTH-BTPROTO_SCO);
*** DEADLOCK ***
The issue is that the lock hierarchy should go from &hdev->lock -->
hci_cb_list_lock --> sk_lock-AF_BLUETOOTH-BTPROTO_SCO. For example,
one such call trace is:
hci_dev_do_close():
hci_dev_lock();
hci_conn_hash_flush():
hci_disconn_cfm():
mutex_lock(&hci_cb_list_lock);
sco_disconn_cfm():
sco_conn_del():
lock_sock(sk);
However, in sco_sock_connect, we call lock_sock before calling
hci_dev_lock inside sco_connect, thus inverting the lock hierarchy.
We fix this by pulling the call to hci_dev_lock out from sco_connect.

The kernel test robot reports undefined reference after we report wakeup
reason to mac80211. This is because CONFIG_PM is not defined in the testing
configuration file. In fact, functions within wow.c are used if CONFIG_PM
is defined, so use CONFIG_PM to decide whether we build this file or not.
The reported messages are:

The TX A-MPDU aggregation is not handled in the driver since the

Start and stop the TX BA session by tracking the TX aggregation

Locks have two sets of op arrays, fl_lmops for the lock manager (lockd
or nfsd), fl_ops for the filesystem. The server-side lockd code has
been setting its own fl_ops, which leads to confusion (and crashes) in
the reexport case, where the filesystem expects to be the only one
setting fl_ops.
And there's no reason for it that I can see-the lm_get/put_owner ops do
the same job.

The PAC tests check to see if the system supports the relevant PAC features
but instead of skipping the tests if they can't be executed they fail the
tests which makes things look like they're not working when they are.

[ Upstream commit 79f5962baea74ce1cd4e5949598944bff854b166 ]
The maximum MTU was set to 2304, which is the maximum MSDU size. While
this is valid for normal WLAN interfaces, it is too low for monitor
interfaces. A monitor interface may receive and inject MPDU frames, and
the maximum MPDU frame size is larger than 2304. The MPDU may also
contain an A-MSDU frame, in which case the size may be much larger than
the MTU limit. Since the maximum size of an A-MSDU depends on the PHY
mode of the transmitting STA, it is not possible to set an exact MTU
limit for a monitor interface. Now the maximum MTU for a monitor
interface is unrestricted.

[ Upstream commit d1340f80f0b8066321b499a376780da00560e857 ]
In the gfs2 withdraw sequence, the dlm protocol is unmounted with a call
to lm_unmount. After a withdraw, users are allowed to unmount the
withdrawn file system. But at that point we may still have glocks left
over that we need to free via unmount's call to gfs2_gl_hash_clear.
These glocks may have never been completed because of whatever problem
caused the withdraw (IO errors or whatever).
Before this patch, function gdlm_put_lock would still try to call into
dlm to unlock these leftover glocks, which resulted in dlm returning
-EINVAL because the lock space was abandoned. These glocks were never
freed because there was no mechanism after that to free them.
This patch adds a check to gdlm_put_lock to see if the locking protocol
was inactive (DFL_UNMOUNT flag) and if so, free the glock and not
make the invalid call into dlm.
I could have combined this "if" with the one that follows, related to
leftover glock LVBs, but I felt the code was more readable with its own
if clause.

[ Upstream commit 11c4b3e264d68ba6dcd52d12dbcfd3f564f2f137 ]
qfprom_disable_fuse_blowing() disables a bunch of resources,
and then does a few register writes in the 'conf' address
space.
It works perhaps because the resources are needed only for the
'raw' register space writes, and that the 'conf' space allows
read/writes regardless.
However that makes the code look confusing, so just move the
register writes before turning off the resources in the
function.

[ Upstream commit a19effb6dbe5bd1be77a6d68eba04dba8993ffeb ]
The Runtime PM subsystem will force the device "fd4a0000.zynqmp-display"
to enter suspend state while booting if the following conditions are met:
- the usage counter is zero (pm_runtime_get_sync hasn't been called yet)
- no 'active' children (no zynqmp-dp-snd-xx node under dpsub node)
- no other device in the same power domain (dpdma node has no
"power-domains = <&zynqmp_firmware PD_DP>" property)
So there is a scenario as below:
1) DP device enters suspend state <- call zynqmp_gpd_power_off
2) zynqmp_disp_crtc_setup_clock <- configurate register VPLL_FRAC_CFG
3) pm_runtime_get_sync <- call zynqmp_gpd_power_on and clear previous
VPLL_FRAC_CFG configuration
4) clk_prepare_enable(disp->pclk) <- enable failed since VPLL_FRAC_CFG
configuration is corrupted
>From above, we can see that pm_runtime_get_sync may clear register
VPLL_FRAC_CFG configuration and result the failure of clk enabling.
Putting pm_runtime_get_sync at the very beginning of the function
zynqmp_disp_crtc_atomic_enable can resolve this issue.

The GW71xx has a USB Type-C connector with USB 2.0 signaling. GPIO1_12
is the power-enable to the TPS25821 Source controller and power switch
responsible for monitoring the CC pins and enabling VBUS. Therefore
GPIO1_12 must always be enabled and the vbus output enable from the
IMX8MM can be ignored.
To fix USB OTG VBUS enable a pull-up on GPIO1_12 to always power the
TPS25821 and change the regulator output to GPIO1_10 which is
unconnected.

[ Upstream commit 74fc4f828769cca1c3be89ea92cb88feaa27ef52 ]
Currently, when creating an ingress qdisc on an indirect device before
the driver registered for callbacks, the driver will not have a chance
to register its filter configuration callbacks.
To fix that, modify the code such that it keeps track of all the ingress
qdiscs that call flow_indr_dev_setup_offload(). When a driver calls
flow_indr_dev_register(), go through the list of tracked ingress qdiscs
and call the driver callback entry point so as to give it a chance to
register its callback.

In current wow flow, driver calls rtw_wow_fw_start and sleep for 100ms,
to wait firmware finish preliminary work and then update the value of
WOWLAN_WAKE_REASON register to zero. But later firmware will start wow
function with power-saving mode, in which mode the value of
WOWLAN_WAKE_REASON register is 0xea. So driver may get 0xea value and
return fail. We use read_poll_timeout instead to check the value to avoid
this issue.

[ Upstream commit 66cce9e73ec61967ed1f97f30cee79bd9a2bb7ee ]
When a remote usb device is attached to the local Virtual USB
Host Controller Root Hub port, the bound device driver may send
a port reset command.
vhci_hcd accepts port resets only when the device doesn't have
port address assigned to it. When reset happens device is in
assigned/used state and vhci_hcd rejects it leaving the port in
a stuck state.
This problem was found when a blue-tooth or xbox wireless dongle
was passed through using usbip.
A few drivers reset the port during probe including mt76 driver
specific to this bug report. Fix the problem with a change to
honor reset requests when device is in used state (VDEV_ST_USED).

Currently, outgoing packets larger than 1496 bytes are dropped when
tagged VLAN is used on a switch port.
Add the frame check sequence length to the value of the register
GSWIP_MAC_FLEN to fix this. This matches the lantiq_ppa vendor driver,
which uses a value consisting of 1518 bytes for the MAC frame, plus the
lengths of special tag and VLAN tags.

In line 849 (#1), "mlx5dr_htbl_put(cur_htbl);" drops the reference to
cur_htbl and may cause cur_htbl to be freed.
However, cur_htbl is subsequently used in the next line, which may result
in an use-after-free bug.
Fix this by calling mlx5dr_err() before the cur_htbl is put.

[ Upstream commit deedf9b97cd4ef45da476c9bdd2a5f3276053956 ]
The scan request processing populated the direct SSIDs
in the FW scan request command also for 6GHz scan, which is not
needed and might result in unexpected behavior.
Fix the code to add the direct SSIDs only in case the scan
is not a 6GHz scan.

[ Upstream commit 258c81b341c8025d79073ce2d6ce19dcdc7d10d2 ]
In vhci_device_unlink_cleanup(), the URBs for unsent unlink requests are
not given back. This sometimes causes usb_kill_urb to wait indefinitely
for that urb to be given back. syzbot has reported a hung task issue [1]
for this.
To fix this, give back the urbs corresponding to unsent unlink requests
(unlink_tx list) similar to how urbs corresponding to unanswered unlink
requests (unlink_rx list) are given back.

From: Mikulas Patocka <[email protected]>
commit 030f653078316a9cc9ca6bd1b0234dcf858be35d upstream.
I was debugging some crashes on parisc and I found out that there is a
crash possibility if a function using alloca is interrupted by a signal.
The reason for the crash is that the gcc alloca implementation leaves
garbage in the upper 32 bits of the sp register. This normally doesn't
matter (the upper bits are ignored because the PSW W-bit is clear),
however the signal delivery routine in the kernel uses full 64 bits of sp
and it fails with -EFAULT if the upper 32 bits are not zero.
I created this program that demonstrates the problem:
#include <stdlib.h>
#include <unistd.h>
#include <signal.h>
#include <alloca.h>
static __attribute__((noinline,noclone)) void aa(int *size)
{
void * volatile p = alloca(-*size);
while (1) ;
}
static void handler(int sig)
{
write(1, "signal delivered\n", 17);
_exit(0);
}
int main(void)
{
int size = -0x100;
signal(SIGALRM, handler);
alarm(1);
aa(&size);
}
If you compile it with optimizations, it will crash.
The "aa" function has this disassembly:
000106a0 <aa>:
106a0: 08 03 02 41 copy r3,r1
106a4: 08 1e 02 43 copy sp,r3
106a8: 6f c1 00 80 stw,ma r1,40(sp)
106ac: 37 dc 3f c1 ldo -20(sp),ret0
106b0: 0c 7c 12 90 stw ret0,8(r3)
106b4: 0f 40 10 9c ldw 0(r26),ret0 ; ret0 = 0x00000000FFFFFF00
106b8: 97 9c 00 7e subi 3f,ret0,ret0 ; ret0 = 0xFFFFFFFF0000013F
106bc: d7 80 1c 1a depwi 0,31,6,ret0 ; ret0 = 0xFFFFFFFF00000100
106c0: 0b 9e 0a 1e add,l sp,ret0,sp ; sp = 0xFFFFFFFFxxxxxxxx
106c4: e8 1f 1f f7 b,l,n 106c4 <aa+0x24>,r0
This patch fixes the bug by truncating the "usp" variable to 32 bits.

commit 7cf209ba8a86410939a24cb1aeb279479a7e0ca6 upstream.
Patch series "mm/memory_hotplug: preparatory patches for new online policy and memory"
These are all cleanups and one fix previously sent as part of [1]:
[PATCH v1 00/12] mm/memory_hotplug: "auto-movable" online policy and memory
groups.
These patches make sense even without the other series, therefore I pulled
them out to make the other series easier to digest.
[1] https://lkml.kernel.org/r/[email protected]
This patch (of 4):
Checkpatch complained on a follow-up patch that we are using "unsigned"
here, which defaults to "unsigned int" and checkpatch is correct.
As we will search for a fitting zone using the wrong pfn, we might end
up onlining memory to one of the special kernel zones, such as ZONE_DMA,
which can end badly as the onlined memory does not satisfy properties of
these zones.
Use "unsigned long" instead, just as we do in other places when handling
PFNs. This can bite us once we have physical addresses in the range of
multiple TB.

commit 92bd92c44d0d9be5dcbcda315b4be4b909ed9740 upstream.
Commit 2f015ec6eab6 ("drm/dp_mst: Add sideband down request tracing +
selftests") added some debug code for sideband message tracing. But
it seems to have unintentionally changed the behavior on sideband message
failure. It catches and returns failure only if DRM_UT_DP is enabled.
Otherwise it ignores the error code and returns success. So on an MST
unplug, the caller is unaware that the clear payload message failed and
ends up waiting for 4 seconds for the response. Fixes the issue by
returning the proper error code.
Changes in V2:
-- Revise commit text as review comment
-- add Fixes text
Changes in V3:
-- remove "unlikely" optimization

commit 7fdc48cc63a30fa3480d18bdd8c5fff2b9b15212 upstream.
Jobs can be in-flight when the file descriptor is closed (either because
the process did not terminate properly, or because it didn't wait for
all GPU jobs to be finished), and apparently panfrost_job_close() does
not cancel already running jobs. Let's refcount the MMU context object
so it's lifetime is no longer bound to the FD lifetime and running jobs
can finish properly without generating spurious page faults.

[ Upstream commit f657f8eef3ff870552c9fd2839e0061046f44618 ]
NFS implements blocking locks by blocking inside its lock method. In
the reexport case, this blocks the nfs server thread, which could lead
to deadlocks since an nfs server thread might be required to unlock the
conflicting lock. It also causes a crash, since the nfs server thread
assumes it can free the lock when its lm_notify lock callback is called.
Ideal would be to make the nfs lock method return without blocking in
this case, but for now it works just not to attempt blocking locks. The
difference is just that the original client will have to poll (as it
does in the v4.0 case) instead of getting a callback when the lock's
available.

commit 32b2397c1e56f33b0b1881def965bb89bd12f448 upstream.
There is a use after free crash when the pmem driver tears down its
mapping while I/O is still inbound.
This is triggered by driver unbind, "ndctl destroy-namespace", while I/O
is in flight.
Fix the sequence of blk_cleanup_queue() vs memunmap().
The crash signature is of the form:

[ Upstream commit 0c75fc7193387776c10f7c7b440d93496e3d5e21 ]
When more than one FE is connected to a BE, e.g. in a mixing use case,
the BE can be triggered multiple times when the FE are opened/started
concurrently. This race condition is problematic in the case of
SoundWire BE dailinks, and this is not desirable in a general
case. The code carefully checks when the BE can be stopped or
hw_free'ed, but the trigger code does not use any mutual exclusion.
Fix by using the same spinlock already used to check FE states, and
set the state before the trigger. In case of errors, the initial
state will be restored.
This patch does not change how the triggers are handled, it only makes
sure the states are handled in critical sections.

[ Upstream commit 8678fd31f2d3eb14f2b8b39c9bc266f16fa24b22 ]
When receiving a beacon or probe response, we should update the
boottime_ns field which is the timestamp the frame was received at.
(cf mac80211.h)
This fixes a scanning issue with Android since it relies on this
timestamp to determine when the AP has been seen for the last time
(via the nl80211 BSS_LAST_SEEN_BOOTTIME parameter).

[ Upstream commit 2847c46c61486fd8bca9136a6e27177212e78c69 ]
This reverts commit 5d5323a6f3625f101dbfa94ba3ef7706cce38760.
That commit effectively disabled Intel host initiated U1/U2 lpm for devices
with periodic endpoints.
Before that commit we disabled host initiated U1/U2 lpm if the exit latency
was larger than any periodic endpoint service interval, this is according
to xhci spec xhci 1.1 specification section 4.23.5.2
After that commit we incorrectly checked that service interval was smaller
than U1/U2 inactivity timeout. This is not relevant, and can't happen for
Intel hosts as previously set U1/U2 timeout = 105% * service interval.
Patch claimed it solved cases where devices can't be enumerated because of
bandwidth issues. This might be true but it's a side effect of accidentally
turning off lpm.
exit latency calculations have been revised since then

commit f34ee9cb2c5ac5af426fee6fa4591a34d187e696 upstream.
In the numa=off kernel command-line configuration init_chip_info() loops
around the number of chips and attempts to copy the cpumask of that node
which is NULL for all iterations after the first chip.
Hence, store the cpu mask for each chip instead of derving cpumask from
node while populating the "chips" struct array and copy that to the
chips[i].mask

If IRQ occurs between calling devm_request_threaded_irq() and
initializing dwc3_imx->dwc3, then null pointer dereference occurs
since dwc3_imx->dwc3 is used in dwc3_imx8mp_interrupt().
The patch puts registration of the interrupt handler after
initializing of neccesery data.

Upon further examination, it was discovered that the css structure was
associated with hugetlb reservations.
For private hugetlb mappings the vma points to a reserve map that
contains a pointer to the css. At mmap time, reservations are set up
and a reference to the css is taken. This reference is dropped in the
vma close operation; hugetlb_vm_op_close. However, if a vma is split no
additional reference to the css is taken yet hugetlb_vm_op_close will be
called twice for the split vma resulting in an underflow.
Fix by taking another reference in hugetlb_vm_op_open. Note that the
reference is only taken for the owner of the reserve map. In the more
common fork case, the pointer to the reserve map is cleared for
non-owning vmas.

[ Upstream commit 5ac49f3c2702f269d31cc37eb9308bc557953c4d ]
As follow-up to the discussion with Jakub Kicinski about iavf locking
being insufficient [1] convert iavf to use mutexes instead of bitops.
The locking logic is kept as is, just a drop-in replacement of
enum iavf_critical_section_t with separate mutexes.
The only difference is that the mutexes will be destroyed before the
module is unloaded.

From: Filipe Manana <[email protected]>
[ Upstream commit cceaa89f02f15f232391ae4be214137b0a0285c0 ]
When using the NO_HOLES feature and expanding the size of an inode, we
update the inode's last_trans, last_sub_trans and last_log_commit fields
at maybe_insert_hole() so that a fsync does know that the inode needs to
be logged (by making sure that btrfs_inode_in_log() returns false). This
happens for expanding truncate operations, buffered writes, direct IO
writes and when cloning extents to an offset greater than the inode's
i_size.
However the way we do it is racy, because in between setting the inode's
last_sub_trans and last_log_commit fields, the log transaction ID that was
assigned to last_sub_trans might be committed before we read the root's
last_log_commit and assign that value to last_log_commit. If that happens
it would make a future call to btrfs_inode_in_log() return true. This is
a race that should be extremely unlikely to be hit in practice, and it is
the same that was described by commit bc0939fcfab0d7 ("btrfs: fix race
between marking inode needs to be logged and log syncing").
The fix would simply be to set last_log_commit to the value we assigned
to last_sub_trans minus 1, like it was done in that commit. However
updating these two fields plus the last_trans field is pointless here
because all the callers of btrfs_cont_expand() (which is the only
caller of maybe_insert_hole()) always call btrfs_set_inode_last_trans()
or btrfs_update_inode() after calling btrfs_cont_expand(). Calling either
btrfs_set_inode_last_trans() or btrfs_update_inode() guarantees that the
next fsync will log the inode, as it makes btrfs_inode_in_log() return
false.
So just remove the code that explicitly sets the inode's last_trans,
last_sub_trans and last_log_commit fields.

commit f9addd85fbfacf0d155e83dbee8696d6df5ed0c7 upstream.
H_GetPerformanceCounterInfo (0xF080) hcall returns the counter data in
the result buffer. Result buffer has specific format defined in the PAPR
specification. One of the fields is counter offset and width of the
counter data returned.
Counter data are returned in a unsigned char array in big endian byte
order. To get the final counter data, the values must be left shifted
byte at a time. But commit 220a0c609ad17 ("powerpc/perf: Add support for
the hv gpci (get performance counter info) interface") made the shifting
bitwise and also assumed little endian order. Because of that, hcall
counters values are reported incorrectly.
In particular this can lead to counters go backwards which messes up the
counter prev vs now calculation and leads to huge counter value
reporting:

Fix the shifting logic to correct match the format, ie. read bytes in

commit 4b511d5bfa74b1926daefd1694205c7f1bcf677f upstream.
Xen PV guests are specifying the highest used PFN via the max_pfn
field in shared_info. This value is used by the Xen tools when saving
or migrating the guest.
Unfortunately this field is misnamed, as in reality it is specifying
the number of pages (including any memory holes) of the guest, so it
is the highest used PFN + 1. Renaming isn't possible, as this is a
public Xen hypervisor interface which needs to be kept stable.
The kernel will set the value correctly initially at boot time, but
when adding more pages (e.g. due to memory hotplug or ballooning) a
real PFN number is stored in max_pfn. This is done when expanding the
p2m array, and the PFN stored there is even possibly wrong, as it
should be the last possible PFN of the just added P2M frame, and not
one which led to the P2M expansion.
Fix that by setting shared_info->max_pfn to the last possible PFN + 1.

commit 732b33d0dbf17e9483f0b50385bf606f724f50a2 upstream.
This patch addresses the following problems:
- priv can never be NULL, so this part of the check is useless
- if the loop ran through the whole list, priv->client is invalid and
it is more appropriate and sufficient to check for the end of
list_for_each_entry loop condition.

btrfs_add_ordered_extent_*() add num_bytes to fs_info->ordered_bytes.
Then, splitting an ordered extent will call btrfs_add_ordered_extent_*()
again for split extents, leading to double counting of the region of
a split extent. These leaked bytes are finally reported at unmount time
as follow:
BTRFS info (device dm-1): at unmount dio bytes count 364544
Fix the double counting by subtracting split extent's size from
fs_info->ordered_bytes.

commit 6f93e834fa7c5faa0372e46828b4b2a966ac61d7 upstream.
The mount option max_inline ranges from 0 to the sectorsize (which is
now equal to page size). But we parse the mount options too early and
before the actual sectorsize is read from the superblock. So the upper
limit of max_inline is unaware of the actual sectorsize and is limited
by the temporary sectorsize 4096, even on a system where the default
sectorsize is 64K.
Fix this by reading the superblock sectorsize before the mount option
parse.

commit b12d93e9958e028856cbcb061b6e64728ca07755 upstream.
The ASMedia ASM1062 SATA controller advertises Max_Payload_Size_Supported
of 512, but in fact it cannot handle incoming TLPs with payload size of
512.
We discovered this issue on PCIe controllers capable of MPS = 512 (Aardvark
and DesignWare), where the issue presents itself as an External Abort.
Bjorn Helgaas says:
Probably ASM1062 reports a Malformed TLP error when it receives a data
payload of 512 bytes, and Aardvark, DesignWare, etc convert this to an
arm64 External Abort. [1]
To avoid this problem, limit the ASM1062 Max Payload Size Supported to 256
bytes, so we set the Max Payload Size of devices that may send TLPs to the
ASM1062 to 256 or less.

The commit 97f9ac3db6612 ("crypto: ccp - Add support for SEV-ES to the
PSP driver") added support to allocate Trusted Memory Region (TMR)
used during the SEV-ES firmware initialization. The TMR gets locked
during the firmware initialization and unlocked during the shutdown.
While the TMR is locked, access to it is disallowed.
Currently, the CCP driver does not shutdown the firmware during the
kexec reboot, leaving the TMR memory locked.
Register a callback to shutdown the SEV firmware on the kexec boot.

[ Upstream commit 50741b70b0cbbafbd9199f5180e66c0c53783a4a ]
Commit d947fb4c965c ("cpuidle: pseries: Fixup exit latency for
CEDE(0)") sets the exit latency of CEDE(0) based on the latency values
of the Extended CEDE states advertised by the platform
On POWER9 LPARs, the firmwares advertise a very low value of 2us for
CEDE1 exit latency on a Dedicated LPAR. The latency advertized by the
PHYP hypervisor corresponds to the latency required to wakeup from the
underlying hardware idle state. However the wakeup latency from the
LPAR perspective should include
1. The time taken to transition the CPU from the Hypervisor into the
LPAR post wakeup from platform idle state
2. Time taken to send the IPI from the source CPU (waker) to the idle
target CPU (wakee).
1. can be measured via timer idle test, where we queue a timer, say
for 1ms, and enter the CEDE state. When the timer fires, in the timer
handler we compute how much extra timer over the expected 1ms have we
consumed. On a a POWER9 LPAR the numbers are
CEDE latency measured using a timer (numbers in ns)
N Min Median Avg 90%ile 99%ile Max Stddev
400 2601 5677 5668.74 5917 6413 9299 455.01
1. and 2. combined can be determined by an IPI latency test where we
send an IPI to an idle CPU and in the handler compute the time
difference between when the IPI was sent and when the handler ran. We
see the following numbers on POWER9 LPAR.
CEDE latency measured using an IPI (numbers in ns)
N Min Median Avg 90%ile 99%ile Max Stddev
400 711 7564 7369.43 8559 9514 9698 1200.01
Suppose, we consider the 99th percentile latency value measured using
the IPI to be the wakeup latency, the value would be 9.5us This is in
the ballpark of the default value of 10us.
Hence, use the exit latency of CEDE(0) based on the latency values
advertized by platform only from POWER10 onwards. The values
advertized on POWER10 platforms is more realistic and informed by the
latency measurements. For earlier platforms stick to the default value
of 10us. The fix was suggested by Michael Ellerman.

commit d212dcee27c1f89517181047e5485fcbba4a25c2 upstream.
irq_mask and irq_unmask callbacks need to be properly guarded by raw spin
locks as masking/unmasking procedure needs atomic read-modify-write
operation on hardware register.

commit 8a6430ab9c9c87cb64c512e505e8690bbaee190b upstream.
Commit ca6bfcb2f6d9 ("libata: Enable queued TRIM for Samsung SSD 860")
limited the existing ATA_HORKAGE_NO_NCQ_TRIM quirk from "Samsung SSD 8*",
covering all Samsung 800 series SSDs, to only apply to "Samsung SSD 840*"
and "Samsung SSD 850*" series based on information from Samsung.
But there is a large number of users which is still reporting issues
with the Samsung 860 and 870 SSDs combined with Intel, ASmedia or
Marvell SATA controllers and all reporters also report these problems
going away when disabling queued trims.
Note that with AMD SATA controllers users are reporting even worse
issues and only completely disabling NCQ helps there, this will be
addressed in a separate patch.

commit 94ffb0a282872c2f4b14f757fa1aef2302aeaabb upstream.
The attempt to find and activate a free worker for new work is currently
combined with creating a new one if we don't find one, but that opens
io-wq up to a race where the worker that is found and activated can
put itself to sleep without knowing that it has been selected to perform
this new work.
Fix this by moving the activation into where we add the new work item,
then we can retain it within the wqe->lock scope and elimiate the race
with the worker itself checking inside the lock, but sleeping outside of
it.

commit 02bcec3ea5591720114f586960490b04b093a09e upstream.
Measurements in different conditions showed that aardvark hardware PIO
response can take up to 1.44s. Increase wait timeout from 1ms to 1.5s to
ensure that we do not miss responses from hardware. After 1.44s hardware
returns errors (e.g. Completer abort).
The previous two patches fixed checking for PIO status, so now we can use
it to also catch errors which are reported by hardware after 1.44s.
After applying this patch, kernel can detect and print PIO errors to dmesg:
[ 6.879999] advk-pcie d0070000.pcie: Non-posted PIO Response Status: CA, 0xe00 @ 0x100004
[ 6.896436] advk-pcie d0070000.pcie: Posted PIO Response Status: COMP_ERR, 0x804 @ 0x100004

[ 6.929663] advk-pcie d0070000.pcie: Non-posted PIO Response Status: CA, 0xe00 @ 0x100010

[ 6.994328] advk-pcie d0070000.pcie: Posted PIO Response Status: COMP_ERR, 0x804 @ 0x100004
Without this patch kernel prints only a generic error to dmesg:

[ Upstream commit d6236a98b3bab07c0a1455fd1ab46f79c3978cdc ]
The intention of the layout barrier is to ensure that we do not update
the layout to match an older value than the current expectation. Fix the
test in pnfs_layout_stateid_blocked() to reflect that it is legal for
the seqid of the stateid to match that of the barrier.

(since seqid '0' is an illegal value), so we should always allow it to

commit 210f9df02611cbe641ced3239122b270fd907d86 upstream.
The selftest for ftrace checks some features by checking if the README has
text that states the feature is supported by that kernel. Unfortunately,
this check gives false positives because it many not be checked if there's
spaces in the string to check. This is due to the compare between the
required variable with the ":README" string stripped, because neither has
quotes around them.

The ingenic_set_bias() function's "bias" argument is not a

This should fix the bias config not working on the X2000(E) SoCs.

commit 1b73e588f47397dee6e4bdfd953e0306c60b5fe5 upstream.
Casting a small array of u8 to an unsigned long is *never* OK:
- it does funny thing when the array size is less than that of a long,
as it accesses random places in the stack
- it makes everything even more fun with a BE kernel
Fix this by building the unsigned long used as a bitmap byte by byte,
in a way that works across endianess and has no undefined behaviours.
An extra BUILD_BUG_ON() catches the unlikely case where the array
would be larger than a single unsigned long.

commit e16460707e94c3d4c1b5418cb68b28b8efa903b2 upstream.
I've been debugging an early ENOSPC problem in production and finally
root caused it to this problem. When we switched to the per-inode in
38d715f494f2 ("btrfs: use btrfs_start_delalloc_roots in
shrink_delalloc") I pulled out the async extent handling, because we
were doing the correct thing by calling filemap_flush() if we had async
extents set. This would properly wait on any async extents by locking
the page in the second flush, thus making sure our ordered extents were
properly set up.
However when I switched us back to page based flushing, I used
sync_inode(), which allows us to pass in our own wbc. The problem here
is that sync_inode() is smarter than the filemap_* helpers, it tries to
avoid calling writepages at all. This means that our second call could
skip calling do_writepages altogether, and thus not wait on the pagelock
for the async helpers. This means we could come back before any ordered
extents were created and then simply continue on in our flushing
mechanisms and ENOSPC out when we have plenty of space to use.
Fix this by putting back the async pages logic in shrink_delalloc. This
allows us to bulk write out everything that we need to, and then we can
wait in one place for the async helpers to catch up, and then wait on
any ordered extents that are created.

commit b49a0e69a7b1a68c8d3f64097d06dabb770fec96 upstream.
The check mixes pages (vm_pgoff) with bytes (vm_start, vm_end) on one
side of the comparison, and uses resource address (rather than just the
resource size) on the other side of the comparison.
This can allow malicious userspace to easily bypass the boundary check and
map pages that are located outside memory-region reserved by the driver.

This happens when close_ctree is called while a dev_replace hasn't
completed. In close_ctree, we suspend the dev_replace, but keep the
replace target around so that we can resume the dev_replace procedure
when we mount the root again. This is the call trace:
close_ctree():
btrfs_dev_replace_suspend_for_unmount();
btrfs_close_devices():
btrfs_close_fs_devices():
btrfs_close_one_device():
ASSERT(!test_bit(BTRFS_DEV_STATE_REPLACE_TGT,
&device->dev_state));
However, since the replace target sticks around, there is a device
with BTRFS_DEV_STATE_REPLACE_TGT set on close, and we fail the
assertion in btrfs_close_one_device.
To fix this, if we come across the replace target device when
closing, we should properly reset it back to allocation state. This
fix also ensures that if a non-target device has a corrupted state and
has the BTRFS_DEV_STATE_REPLACE_TGT bit set, the assertion will still
catch the error.

commit b30d0289de72c62516df03fdad8d53f552c69839 upstream.
The merge_fdt_bootargs() function by definition consumes more than 1024
bytes of stack because it has a 1024 byte command line on the stack,
meaning that we always get a warning when building this file:
arch/arm/boot/compressed/atags_to_fdt.c: In function 'merge_fdt_bootargs':
arch/arm/boot/compressed/atags_to_fdt.c:98:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]
However, as this is the decompressor and we know that it has a very shallow
call chain, and we do not actually risk overflowing the kernel stack
at runtime here.
This just shuts up the warning by disabling the warning flag for this
file.
Tested on Nexus 7 2012 builds.

commit 00823dcbdd415c868390feaca16f0265101efab4 upstream.
Previously we assumed that all Root Ports and Switch Downstream Ports
supported Link Bandwidth Notification. Per spec, this is only required
for Ports supporting Links wider than x1 and/or multiple Link speeds
(PCIe r5.0, sec 7.5.3.6).
Because we assumed all Ports supported it, we tried to set up a Bandwidth
Notification IRQ, which failed for devices that don't support IRQs at all,
which meant pcieport didn't attach to the Port at all.
Check the Link Bandwidth Notification Capability bit and enable the service
only when the Port supports it.

commit d195d7aac09bddabc2c8326fb02fcec2b0a2de02 upstream.
If the operating channel is the first in the scan list, it was seen that
a finish scan request would be sent before a start scan request was
sent, causing the firmware to fail all future scans. Track the current
channel being scanned to avoid requesting the scan finish before it
starts.

io_try_cancel_userdata() can be called from io_async_cancel() executing
in the io-wq context, so the warning fires, which is there to alert
anyone accessing task->io_uring->io_wq in a racy way. However,
io_wq_put_and_exit() always first waits for all threads to complete,
so the only detail left is to zero tctx->io_wq after the context is
removed.
note: one little assumption is that when IO_WQ_WORK_CANCEL, the executor
won't touch ->io_wq, because io_wq_destroy() might cancel left pending
requests in such a way.

commit 528b16bfc3ae5f11638e71b3b63a81f9999df727 upstream.
On systems with many cores using dm-crypt, heavy spinlock contention in
percpu_counter_compare() can be observed when the page allocation limit
for a given device is reached or close to be reached. This is due
to percpu_counter_compare() taking a spinlock to compute an exact
result on potentially many CPUs at the same time.
Switch to non-exact comparison of allocated and allowed pages by using
the value returned by percpu_counter_read_positive() to avoid taking
the percpu_counter spinlock.
This may over/under estimate the actual number of allocated pages by at
most (batch-1) * num_online_cpus().
Currently, batch is bounded by 32. The system on which this issue was
first observed has 256 CPUs and 512GB of RAM. With a 4k page size, this
change may over/under estimate by 31MB. With ~10G (2%) allowed dm-crypt
allocations, this seems an acceptable error. Certainly preferred over
running into the spinlock contention.
This behavior was reproduced on an EC2 c5.24xlarge instance with 96 CPUs
and 192GB RAM as follows, but can be provoked on systems with less CPUs
as well.
* Disable swap
* Tune vm settings to promote regular writeback
$ echo 50 > /proc/sys/vm/dirty_expire_centisecs
$ echo 25 > /proc/sys/vm/dirty_writeback_centisecs
$ echo $((128 * 1024 * 1024)) > /proc/sys/vm/dirty_background_bytes
* Create 8 dmcrypt devices based on files on a tmpfs
* Create and mount an ext4 filesystem on each crypt devices
* Run stress-ng --hdd 8 within one of above filesystems
Total %system usage collected from sysstat goes to ~35%. Write throughput
on the underlying loop device is ~2GB/s. perf profiling an individual
kworker kcryptd thread shows the following profile, indicating spinlock
contention in percpu_counter_compare():

After applying this patch and running the same test, %system usage is
lowered to ~7% and write throughput on the loop device increases
to ~2.7GB/s. perf report shows mempool_alloc() as ~8% rather than ~62%
in the profile and not hitting the percpu_counter() spinlock anymore.

[ Upstream commit d04691d373e75c83424b85c0e68e4a3f9370c10d ]
After commit 7cbd631d4dec ("cpuidle: pseries: Fixup CEDE0 latency only
for POWER10 onwards"), pseries_idle_probe() is no longer inlined when
compiling with clang, which causes a modpost warning:
WARNING: modpost: vmlinux.o(.text+0xc86a54): Section mismatch in
reference from the function pseries_idle_probe() to the function
.init.text:fixup_cede0_latency()
The function pseries_idle_probe() references
the function __init fixup_cede0_latency().
This is often because pseries_idle_probe lacks a __init
annotation or the annotation of fixup_cede0_latency is wrong.
pseries_idle_probe() is a non-init function, which calls
fixup_cede0_latency(), which is an init function, explaining the
mismatch. pseries_idle_probe() is only called from
pseries_processor_idle_init(), which is an init function, so mark
pseries_idle_probe() as __init so there is no more warning.

[ Upstream commit 9c7248bb8de31f51c693bfa6a6ea53b1c07e0fa8 ]
When a LPAR is migratable, we should consider the maximum possible NUMA
node instead of the number of NUMA nodes from the actual system.
The DT property 'ibm,current-associativity-domains' defines the maximum
number of nodes the LPAR can see when running on that box. But if the
LPAR is being migrated on another box, it may see up to the nodes
defined by 'ibm,max-associativity-domains'. So if a LPAR is migratable,
that value should be used.
Unfortunately, there is no easy way to know if an LPAR is migratable or
not. The hypervisor exports the property 'ibm,migratable-partition' in
the case it set to migrate partition, but that would not mean that the
current partition is migratable.
Without this patch, when a LPAR is started on a 2 node box and then
migrated to a 3 node box, the hypervisor may spread the LPAR's CPUs on
the 3rd node. In that case if a CPU from that 3rd node is added to the
LPAR, it will be wrongly assigned to the node because the kernel has
been set to use up to 2 nodes (the configuration of the departure node).
With this patch applies, the CPU is correctly added to the 3rd node.

Commit 1abd18d1a51a ("pinctrl: samsung: Register pinctrl before GPIO")
changes the order of GPIO and pinctrl registration: now pinctrl is
registered before GPIO. That means gpio_chip->ngpio is not set when
samsung_pinctrl_register() called, and one cannot rely on that value
anymore. Use `pin_bank->nr_pins' instead of `pin_bank->gpio_chip.ngpio'
to fix mentioned inconsistency.

[ Upstream commit b763f3bedc2da2edf81bba550430847f561eae0e ]
Restruct f2fs page private layout for below reasons:
There are some cases that f2fs wants to set a flag in a page to
indicate a specified status of page:
a) page is in transaction list for atomic write
b) page contains dummy data for aligned write
c) page is migrating for GC
d) page contains inline data for inline inode flush
e) page belongs to merkle tree, and is verified for fsverity
f) page is dirty and has filesystem/inode reference count for writeback
g) page is temporary and has decompress io context reference for compression
There are existed places in page structure we can use to store
f2fs private status/data:
- page.flags: PG_checked, PG_private
- page.private
However it was a mess when we using them, which may cause potential
confliction:
page.private PG_private PG_checked page._refcount (+1 at most)
a) -1 set +1
b) -2 set
c), d), e) set
f) 0 set +1
g) pointer set
The other problem is page.flags has no free slot, if we can avoid set
zero to page.private and set PG_private flag, then we use non-zero value
to indicate PG_private status, so that we may have chance to reclaim
PG_private slot for other usage. [1]
The other concern is f2fs has bad scalability in aspect of indicating
more page status.
So in this patch, let's restructure f2fs' page.private as below to
solve above issues:
Layout A: lowest bit should be 1
| bit0 = 1 | bit1 | bit2 | ... | bit MAX | private data .... |
bit 0 PAGE_PRIVATE_NOT_POINTER
bit 1 PAGE_PRIVATE_ATOMIC_WRITE
bit 2 PAGE_PRIVATE_DUMMY_WRITE
bit 3 PAGE_PRIVATE_ONGOING_MIGRATION
bit 4 PAGE_PRIVATE_INLINE_INODE
bit 5 PAGE_PRIVATE_REF_RESOURCE
bit 6- f2fs private data
Layout B: lowest bit should be 0
page.private is a wrapped pointer.
After the change:
page.private PG_private PG_checked page._refcount (+1 at most)
a) 11 set +1
b) 101 set +1
c) 1001 set +1
d) 10001 set +1
e) set
f) 100001 set +1
g) pointer set +1

2.30.2
From: Ahmad Fatoum <[email protected]>
[ Upstream commit d36207b848a6490e14664e2197a1c8ab51d8148e ]
On the i.MX8M*, the TF-A exposes a SiP (Silicon Provider) service
for DDR frequency scaling. The imx8m-ddrc-devfreq driver calls the
SiP and then does clk_set_parent on the DDR muxes to synchronize
the clock tree.
Since 936c383673b9 ("clk: imx: fix composite peripheral flags"),
these TF-A managed muxes have SET_PARENT_GATE set, which results
in imx8m-ddrc-devfreq's clk_set_parent after SiP failing with -EBUSY:
echo 25000000 > userspace/set_freq
imx8m-ddrc-devfreq 3d400000.memory-controller: failed to set
dram_apb parent: -16
Fix this by adding a new i.MX composite flag for firmware managed
clocks, which clears SET_PARENT_GATE.
This is safe to do, because updating the Linux clock tree to reflect
reality will always be glitch-free.

[ Upstream commit 3c69a5f22223fa3e312689ec218b5059784d49d7 ]
Incase of random sampling, there can be scenarios where
Sample Instruction Address Register(SIAR) may not latch
to the sampled instruction and could result in
the value of 0. In these scenarios it is preferred to
return regs->nip. These corner cases are seen in the
previous generation (p9) also.
Patch adds the check for SIAR value along with regs_use_siar
and siar_valid checks so that the function will return
regs->nip incase SIAR is zero.
Patch drops the code under PPMU_P10_DD1 flag check
which handles SIAR 0 case only for Power10 DD1.

[ Upstream commit c16edf5ff8ece9c4135175da4103cee1bec360be ]
'clk_init_data' for gates is setting up 'CLK_IS_CRITICAL'
flag for all of them. This was being doing because some
drivers of this SoC might not be ready to use the clock
and we don't wanted the kernel to disable them since default
behaviour without clock driver was to set all gate bits to
enabled state. After a bit more testing and checking driver
code it is safe to remove this flag and just let the kernel
to disable those gates that are not in use. No regressions
seems to appear.

[ Upstream commit 1d78dfde33a02da1d816279c2e3452978b7abd39 ]
Since commit e1a1ef84cd07 ("KVM: PPC: Book3S: Allocate guest TCEs on
demand too"), pages for TCE tables for KVM guests are allocated only
when needed. This allows skipping any update when clearing TCEs. This
works mostly fine as TCE updates are handled when the MMU is enabled.
The realmode handlers fail with H_TOO_HARD when pages are not yet
allocated, except when clearing a TCE in which case KVM prints a warning
and proceeds to dereference a NULL pointer, which crashes the host OS.
This has not been caught so far as the change in commit e1a1ef84cd07 is
reasonably new, and POWER9 runs mostly radix which does not use realmode
handlers. With hash, the default TCE table is memset() by QEMU when the
machine is reset which triggers page faults and the KVM TCE device's
kvm_spapr_tce_fault() handles those with MMU on. And the huge DMA
windows are not cleared by VMs which instead successfully create a DMA
window big enough to map the VM memory 1:1 and then VMs just map
everything without clearing.
This started crashing now as commit 381ceda88c4c ("powerpc/pseries/iommu:
Make use of DDW for indirect mapping") added a mode when a dymanic DMA
window not big enough to map the VM memory 1:1 but it is used anyway,
and the VM now is the first (i.e. not QEMU) to clear a just created
table. Note that upstream QEMU needs to be modified to trigger the VM to
trigger the host OS crash.
This replaces WARN_ON_ONCE_RM() with a check and return, and adds
another warning if TCE is not being cleared.

After the L1 saves its PMU SPRs but before loading the L2's PMU SPRs,
switch the pmcregs_in_use field in the L1 lppaca to the value advertised
by the L2 in its VPA. On the way out of the L2, set it back after saving
the L2 PMU registers (if they were in-use).
This transfers the PMU liveness indication between the L1 and L2 at the
points where the registers are not live.
This fixes the nested HV bug for which a workaround was added to the L0
HV by commit 63279eeb7f93a ("KVM: PPC: Book3S HV: Always save guest pmu
for guest capable of nesting"), which explains the problem in detail.
That workaround is no longer required for guests that include this bug
fix.

From: Fabiano Rosas <[email protected]>
[ Upstream commit 5d7d6dac8fe99ed59eee2300e4a03370f94d5222 ]
The __kvmhv_copy_tofrom_guest_radix function was introduced along with
nested HV guest support. It uses the platform's Radix MMU quadrants to
provide a nested hypervisor with fast access to its nested guests
memory (H_COPY_TOFROM_GUEST hypercall). It has also since been added
as a fast path for the kvmppc_ld/st routines which are used during
instruction emulation.
The commit def0bfdbd603 ("powerpc: use probe_user_read() and
probe_user_write()") changed the low level copy function from
raw_copy_from_user to probe_user_read, which adds a check to
access_ok. In powerpc that is:
static inline bool __access_ok(unsigned long addr, unsigned long size)
{
return addr < TASK_SIZE_MAX && size <= TASK_SIZE_MAX - addr;
}
and TASK_SIZE_MAX is 0x0010000000000000UL for 64-bit, which means that
setting the two MSBs of the effective address (which correspond to the
quadrant) now cause access_ok to reject the access.
This was not caught earlier because the most common code path via
kvmppc_ld/st contains a fallback (kvm_read_guest) that is likely to
succeed for L1 guests. For nested guests there is no fallback.
Another issue is that probe_user_read (now __copy_from_user_nofault)
does not return the number of bytes not copied in case of failure, so
the destination memory is not being cleared anymore in
kvmhv_copy_from_guest_radix:
ret = kvmhv_copy_tofrom_guest_radix(vcpu, eaddr, to, NULL, n);
if (ret > 0) <-- always false!
memset(to + (n - ret), 0, ret);
This patch fixes both issues by skipping access_ok and open-coding the
low level __copy_to/from_user_inatomic.

[ Upstream commit 1822b4dedc4d8cab96fd1d87bf8ff98194e29d9b ]
The mux in the clkout path needs the current selected parent to
be enabled for the switch to work. Use the correct mux type
to have the clk framework take care of this requirement.

A quirk was recently added for Elan devices that has same device match
as an entry earlier in the list. The i2c_hid_lookup_quirk function will
always return the last match in the list, so the new entry shadows the
old entry. The quirk in the previous entry, I2C_HID_QUIRK_BOGUS_IRQ,
silenced a flood of messages which have reappeared in the 5.13 kernel.
This change moves the two quirk flags into the same entry.

[ Upstream commit f4919ff59c2828064b4156e3c3600a169909bcf4 ]
Currently, when userspace reads a datagram with a buffer that is
smaller than this datagram, the data will be truncated and only
part of it can be received by users. It doesn't seem right that
users don't know the datagram size and have to use a huge buffer
to read it to avoid the truncation.
This patch to fix it by keeping the skb in rcv queue until the
whole data is read by users. Only the last msg of the datagram
will be marked with MSG_EOR, just as TCP/SCTP does.
Note that this will work as above only when MSG_EOR is set in the
flags parameter of recvmsg(), so that it won't break any old user
applications.

[ Upstream commit 5eff9585de220cdd131237f5665db5e6c6bdf590 ]
Inside drm_clients_info, the rcu_read_lock is held to lock
pid_task()->comm. However, within this protected section, a call to
drm_is_current_master is made, which involves a mutex lock in a future
patch. However, this is illegal because the mutex lock might block
while in the RCU read-side critical section.
Since drm_is_current_master isn't protected by rcu_read_lock, we avoid
this by moving it out of the RCU critical section.

From: Desmond Cheong Zhi Xi <[email protected]>
[ Upstream commit 0b0860a3cf5eccf183760b1177a1dcdb821b0b66 ]
Currently, drm_file.master pointers should be protected by
drm_device.master_mutex when being dereferenced. This is because
drm_file.master is not invariant for the lifetime of drm_file. If
drm_file is not the creator of master, then drm_file.is_master is
false, and a call to drm_setmaster_ioctl will invoke
drm_new_set_master, which then allocates a new master for drm_file and
puts the old master.
Thus, without holding drm_device.master_mutex, the old value of
drm_file.master could be freed while it is being used by another
concurrent process.
However, it is not always possible to lock drm_device.master_mutex to
dereference drm_file.master. Through the fbdev emulation code, this
might occur in a deep nest of other locks. But drm_device.master_mutex
is also the outermost lock in the nesting hierarchy, so this leads to
potential deadlocks.
To address this, we introduce a new spin lock at the bottom of the
lock hierarchy that only serializes drm_file.master. With this change,
the value of drm_file.master changes only when both
drm_device.master_mutex and drm_file.master_lookup_lock are
held. Hence, any process holding either of those locks can ensure that
the value of drm_file.master will not change concurrently.
Since no lock depends on the new drm_file.master_lookup_lock, when
drm_file.master is dereferenced, but drm_device.master_mutex cannot be
held, we can safely protect the master pointer with
drm_file.master_lookup_lock.

[ Upstream commit 6c5c659dfe3f02e08054a6c20019e3886618b512 ]
On a config (such as arch/sh/) which does not set HAS_DMA when MMU
is not set, several ATMEL ASoC drivers select symbols that cause
kconfig warnings. There is one "depends on HAS_DMA" which is no longer
needed. Dropping it eliminates the kconfig warnings and still builds
with no problems reported.
Fix the following kconfig warnings:

[ Upstream commit 892c37f8a3d673b945e951a8754695c119a2b1b0 ]
When starting streaming the driver currently programs the buffer
address to the CAL base-address register and assigns the buffer pointer
to ctx->dma.pending. This is not correct, as the buffer is not
"pending", but active, and causes the first buffer to be needlessly
written twice.
Fix this by assigning the buffer pointer to ctx->dma.active.

of_genpd_add_device() is called before platform_device_register(), as it
needs to attach the genpd before the device is probed. But the spinlock
is only initialized when the device is registered.
Fix this by open-coding the spinlock initialization, cfr.
device_pm_init_common() in the internal drivers/base code, and in the
SuperH early platform code.

[ Upstream commit 61136a12cbed234374ec6f588af57c580b20b772 ]
mv_ehci_enable() did not disable and unprepare clocks in case of
failures of phy_init(). Besides, it did not take into account failures
of ehci_clock_enable() (in effect, failures of clk_prepare_enable()).
The patch fixes both issues and gets rid of redundant wrappers around
clk_prepare_enable() and clk_disable_unprepare() to simplify this a bit.

In f2fs_write_multi_pages(), f2fs_compress_pages() allocates pages for
compression work in cc->cpages[]. Then, f2fs_write_compressed_pages() initiates
bio submission. But, if there's any error before submitting the IOs like early
f2fs_cp_error(), previously it didn't free cpages by f2fs_compress_free_page().
Let's fix memory leak by putting that just before deallocating cc->cpages.

From: Jaegeuk Kim <[email protected]>
[ Upstream commit 9605f75cf36e0bcc0f4ada07b5be712d30107607 ]
The prepare_compress_overwrite() gets/locks a page to prepare a read, and calls
f2fs_read_multi_pages() which checks EOF first. If there's any page beyond EOF,
we unlock the page and set cc->rpages[i] = NULL, which we can't put the page
anymore. This makes page leak, so let's fix by putting that page.

When CONFIG_TRIM_UNUSED_KSYMS is enabled, I see some warnings like this:
nm: arch/x86/entry/vdso/vdso32/note.o: no symbols
$NM (both GNU nm and llvm-nm) warns when no symbol is found in the
object. Suppress the stderr.
Fangrui Song mentioned binutils>=2.37 `nm -q` can be used to suppress
"no symbols" [1], and llvm-nm>=13.0.0 supports -q as well.
We cannot use it for now, but note it as a TODO.

| commit 79edff12060fe7772af08607eff50c0e2486c5ba
| Author: Rob Herring <[email protected]>
| scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9
The reason is the alignment test added to the fdt_ro_probe_(). To fix
this issue, we need to make sure that fdt_buf is aligned.
Since the dtc patch was designed to uncover potential issue, I handle
initial MIPS Malta patch as initial bug.

[ Upstream commit 1698ecb218eb82587dbfc71a2e26ded66e5ecf59 ]
Symptom is random switching of speakers when using multichannel.
Repeatedly running speakertest -c8 occasionally starts with
channels jumbled. This is fixed with HD_CTL_WHOLSMP.
The other bit looks beneficial and apears harmless in testing so
I'd suggest adding it too.
Documentation says: HD_CTL_WHILSMP_SET
Wait for whole sample. When this bit is set MAI transmit will start
only when there is at least one whole sample available in the fifo.
Documentation says: HD_CTL_CHALIGN_SET
Channel Align When Overflow. This bit is used to realign the audio
channels in case of an overflow.
If this bit is set, after the detection of an overflow, equal
amount of dummy words to the missing words will be written to fifo,
filling up the broken sample and maintaining alignment.

[ Upstream commit c445535c3efbfb8cb42d098e624d46ab149664b7 ]
Marking TSC as unstable has a side effect of marking sched_clock as
unstable when TSC is still being used as the sched_clock. This is not
desirable. Hyper-V ultimately uses a paravirtualized clock source that
provides a stable scheduler clock even on systems without TscInvariant
CPU capability. Hence, mark_tsc_unstable() call should be called _after_
scheduler clock has been changed to the paravirtualized clocksource. This
will prevent any unwanted manipulation of the sched_clock. Only TSC will
be correctly marked as unstable.

[ Upstream commit 22c8fd71d3a5e6fe584ccc2c1e8760e5baefd5aa ]
The iavf watchdog task overrides adapter->state to __IAVF_RESETTING
when it detects a pending reset. Then schedules iavf_reset_task() which
takes care of the reset.
The reset task is capable of handling the reset without changing
adapter->state. In fact we lose the state information when the watchdog
task prematurely changes the adapter state. This may lead to a crash if
instead of the reset task the iavf_remove() function gets called before
the reset task.
In that case (if we were in state __IAVF_RUNNING previously) the
iavf_remove() function triggers iavf_close() which fails to close the
device because of the incorrect state information.
This may result in a crash due to pending interrupts.
kernel BUG at drivers/pci/msi.c:357!

The solution is to not touch the adapter->state in iavf_watchdog_task()
and let the reset task handle the state transition.

From: Stefan Assmann <[email protected]>
[ Upstream commit 226d528512cfac890a1619aea4301f3dd314fe60 ]
To avoid races between iavf_init_task(), iavf_reset_task(),
iavf_watchdog_task(), iavf_adminq_task() as well as the shutdown and
remove functions more locking is required.
The current protection by __IAVF_IN_CRITICAL_TASK is needed in
additional places.
- The reset task performs state transitions, therefore needs locking.
- The adminq task acts on replies from the PF in
iavf_virtchnl_completion() which may alter the states.
- The init task is not only run during probe but also if a VF gets stuck
to reinitialize it.
- The shutdown function performs a state transition.
- The remove function performs a state transition and also free's
resources.
iavf_lock_timeout() is introduced to avoid waiting infinitely
and cause a deadlock. Rather unlock and print a warning.

2.30.2
From: Desmond Cheong Zhi Xi <[email protected]>
[ Upstream commit 56f0729a510f92151682ff6c89f69724d5595d6e ]
drm_file->master pointers should be protected by
drm_device.master_mutex or drm_file.master_lookup_lock when being
dereferenced.
However, in drm_lease.c, there are multiple instances where
drm_file->master is accessed and dereferenced while neither lock is
held. This makes drm_lease.c vulnerable to use-after-free bugs.
We address this issue in 2 ways:
1. Add a new drm_file_get_master() function that calls drm_master_get
on drm_file->master while holding on to
drm_file.master_lookup_lock. Since drm_master_get increments the
reference count of master, this prevents master from being freed until
we unreference it with drm_master_put.
2. In each case where drm_file->master is directly accessed and
eventually dereferenced in drm_lease.c, we wrap the access in a call
to the new drm_file_get_master function, then unreference the master
pointer once we are done using it.

[ Upstream commit 97683c851f9cdbd3ea55697cbe2dcb6af4287bbd ]
The naming of the regulator is problematic. VCC is usually a supply
voltage whereas these devices have a separate VREF pin.
Secondly, the regulator core might have provided a stub regulator if
a real regulator wasn't provided. That would in turn have failed to
provide a voltage when queried. So reality was that there was no way
to use the internal reference.
In order to avoid breaking any dts out in the wild, make sure to fallback
to the original vcc naming if vref is not available.

[ Upstream commit f34bf652d680cf65783e7c57d61c94ee87f092bd ]
[Bug][AST2500]
V1:
When AST2500 acts as stand-alone VGA so that DRAM and DVO initialization
have to be achieved by VGA driver with P2A (PCI to AHB) enabling.
However, HW suggests disable Fast reset mode after DRAM initializaton,
because fast reset mode is mainly designed for ARM ICE debugger.
Once Fast reset is checked as enabling, WDT (Watch Dog Timer) should be
first enabled to avoid system deadlock before disable fast reset mode.
V2:
Use to_pci_dev() to get revision of PCI configuration.
V3:
If SCU00 is not unlocked, just enter its password again.
It is unnecessary to clear AHB lock condition and restore WDT default
setting again, before Fast-reset clearing.
V4:
repatch after "error : could not build fake ancestor" resolved.
V5:
Since CVE_2019_6260 item3, Most of AST2500 have disabled P2A(PCIe to AMBA).
However, for backward compatibility, some patches about P2A, such as items
of v5.2 and v5.3, are considered to be upstreamed with comments.
1. Add define macro to improve source readability.
ast_drv.h, ast_main.c, ast_post.c
2. Add comment about "Fast restet" is enabled for ARM-ICE debugger
ast_post.c
3. Add comment about Reset USB port to patch USB unknown device issue

Currently three interconnects are defined for the Qualcomm SC7280
SoC, but this was based on a misunderstanding. There should only be
two interconnects defined: one between the IPA and system memory;
and another between the AP and IPA config space. The bandwidths
defined for the memory and config interconnects do not match what I
understand to be proper values, so update these.

[ Upstream commit fed31a4dd3adb5455df7c704de2abb639a1dc1c0 ]
This commit fixes several typos where CONFIG_TASKS_RCU_TRACE should
instead be CONFIG_TASKS_TRACE_RCU. Among other things, these typos
could cause CONFIG_TASKS_TRACE_RCU_READ_MB=y kernels to suffer from
memory-ordering bugs that could result in false-positive quiescent
states and too-short grace periods.

[ Upstream commit c2e898764245c852bc8ee4857613ba4f3a6d761d ]
Now that usb_endpoint_maxp() only returns the lowest
11 bits from wMaxPacketSize, we should make use of the
usb_endpoint_* helpers instead and remove the unnecessary
max_packet()/hb_mult() macro.

[ Upstream commit 8ae01239609b29ec2eff55967c8e0fe3650cfa09 ]
f_ncm tx timeout can call us with null skb to flush
a pending frame. In this case skb is NULL to begin
with but ceases to be null after dev->wrap() completes.
In such a case in->maxpacket will be read, even though
we've failed to check that 'in' is not NULL.
Though I've never observed this fail in practice,
however the 'flush operation' simply does not make sense with
a null usb IN endpoint - there's nowhere to flush to...
(note that we're the gadget/device, and IN is from the point
of view of the host, so here IN actually means outbound...)

[ Upstream commit 8db11aebdb8f93f46a8513c22c9bd52fa23263aa ]
The logic at dib8000_get_init_prbs() has a few issues:
1. the tables used there has an extra unused value at the beginning;
2. the dprintk() message doesn't write the right value when
transmission mode is not 8K;
3. the array overflow validation is done by the callers.
Rewrite the code to fix such issues.
This should also shut up those smatch warnings:

From: Peter Ujfalusi <[email protected]>
[ Upstream commit bbdd3f4dbe81e19b9123bc54e23ed54517615524 ]
The DIT mode support has not been tested due to lack of platform where it
can be tested.
To be able to use the McASP on OMAP4/5 (only supporting DIT mode) we need
to have DIT mode working in the McASP driver on a know platform.
After hacking around (on BBW, mcasp1.axr1 can be routed out for this) it
appeared that DIT mode is broken.
This patch fixes it up and 16/24 bit audio works along with passthrough,
but I have only tested with DTS example and test files.

[ Upstream commit 6321c7acb82872ef6576c520b0e178eaad3a25c0 ]
Fix the following out-of-bounds warning:
In function 'ip_copy_addrs',
inlined from '__ip_queue_xmit' at net/ipv4/ip_output.c:517:2:
net/ipv4/ip_output.c:449:2: warning: 'memcpy' offset [40, 43] from the object at 'fl' is out of the bounds of referenced subobject 'saddr' with type 'unsigned int' at offset 36 [-Warray-bounds]
449 | memcpy(&iph->saddr, &fl4->saddr,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
450 | sizeof(fl4->saddr) + sizeof(fl4->daddr));
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The problem is that the original code is trying to copy data into a
couple of struct members adjacent to each other in a single call to
memcpy(). This causes a legitimate compiler warning because memcpy()
overruns the length of &iph->saddr and &fl4->saddr. As these are just
a couple of struct members, fix this by using direct assignments,
instead of memcpy().
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

people might think driver is loading VCN firmware. Actually when this

hw_init. Fix the printing message

[ Upstream commit f2c1dac0abcfa93e8b20065b8d6b4b2b6f9990aa ]
Stop supporting different sizes for hashed and non-hashed filter or
route tables. Add BUILD_BUG_ON() calls to verify the sizes of the
fields in the filter/route table initialization immediate command
are the same.
Add a check to ipa_cmd_table_valid() to ensure the size of the
memory region being checked fits within the immediate command field
that must hold it.
Remove two Boolean parameters used only for error reporting. This
actually fixes a bug that would only show up if IPA_VALIDATE were
defined. Define ipa_cmd_table_valid() unconditionally (no longer
dependent on IPA_VALIDATE).

[ Upstream commit 28b6a003bcdfa1fc4603b9185b247ecca7af9bef ]
The virtual machine monitor (QEMU) exposes the pvpanic-pci
device to the guest. On guest side the module exists but
currently isn't loaded automatically. So the driver fails
to be probed and does not its job of handling guest panic
events.
Instead of requiring manual modprobe, let's include a device
database using the MODULE_DEVICE_TABLE macro and let the

[ Upstream commit 8990f96a012f42543005b07d9e482694192e9309 ]
Some versions of the MC firmware wrongly report 0 for register base
address of the DPMCP associated with child DPRC objects thus rendering
them unusable. This is particularly troublesome in ACPI boot scenarios
where the legacy way of extracting this base address from the device
tree does not apply.
Given that DPMCPs share the same base address, workaround this by using
the base address extracted from the root DPRC container.

[ Upstream commit 22414cade8dfec25ab94df52b3a4f7aa8edb6120 ]
The default SOF topology enables SSP capture and DMICs, even though
both of these hardware capabilities are not always available in
hardware (specific versions of HiFiberry and DMIC kit needed).
For the SSP capture, this leads to annoying "SP5-Codec: ASoC: no
backend capture" and "streamSSP5-Codec: ASoC: no users capture at
close - state 0" errors.
Update the quirks to match what the topology needs, which also allows
for the ability to remove SSP capture and DMIC support.

routes to the intmic_*_map[] / *_spk_map[] arrays.

We must not call gfs2_consist (which does a file system withdraw) from
the freeze glock's freeze_go_xmote_bh function because the withdraw
will try to use the freeze glock, thus causing a glock recursion error.
This patch changes freeze_go_xmote_bh to call function
gfs2_assert_withdraw_delayed instead of gfs2_consist to avoid recursion.

[ Upstream commit 92fe24a7db751b80925214ede43f8d2be792ea7b ]
Syzbot reported a corrupted list in kobject_add_internal [1]. This
happens when multiple HCI_EV_SYNC_CONN_COMPLETE event packets with
status 0 are sent for the same HCI connection. This causes us to
register the device more than once which corrupts the kset list.
As this is forbidden behavior, we add a check for whether we're
trying to process the same HCI_EV_SYNC_CONN_COMPLETE event multiple
times for one connection. If that's the case, the event is invalid, so
we report an error that the device is misbehaving, and ignore the
packet.

[ Upstream commit 51f93add3669f1b1f540de1cf397815afbd4c756 ]
The frame_length_lines (0x0340) registers are hard-coded as follows:
- 4208x3118
frame_length_lines = 0x0c50
- 2104x1560
frame_length_lines = 0x0638
- 1048x780
frame_length_lines = 0x034c
The driver exposes the V4L2_CID_VBLANK control in read-only mode and
sets its value to vts_def - height, where vts_def is a mode-dependent
value coming from the supported_modes array. It is set using one of
the following macros defined in the driver:
#define IMX258_VTS_30FPS 0x0c98
#define IMX258_VTS_30FPS_2K 0x0638
#define IMX258_VTS_30FPS_VGA 0x034c
There's a clear mismatch in the value for the full resolution mode i.e.
IMX258_VTS_30FPS. Fix it by rectifying the macro with the value set for
the frame_length_lines register as stated above.

[ Upstream commit f809665ee75fff3f4ea8907f406a66d380aeb184 ]
The range for analog gain mentioned in the datasheet is [0, 480].
The real gain formula mentioned in the datasheet is:
Gain = 512 / (512 – X)
Hence, values larger than 511 clearly makes no sense. The gain
register field is also documented to be of 9-bits in the datasheet.
Certainly, it is enough to infer that, the kernel driver currently
advertises an arbitrary analog gain max. Fix it by rectifying the
value as per the data sheet i.e. 480.

[ Upstream commit 2bc5da528dd570c5ecabc107e6fbdbc55974276f ]
drm_file.master should be protected by either drm_device.master_mutex
or drm_file.master_lookup_lock when being dereferenced. However,
drm_master_get is called on unprotected file_priv->master pointers in
vmw_surface_define_ioctl and vmw_gb_surface_define_internal.
This is fixed by replacing drm_master_get with drm_file_get_master.

2.30.2
From: Yufeng Mo <[email protected]>
[ Upstream commit 220ade77452c15ecb1ab94c3f8aaeb6d033c3582 ]
Some time ago, I reported a calltrace issue
"did not find a suitable aggregator", please see[1].
After a period of analysis and reproduction, I find
that this problem is caused by concurrency.
Before the problem occurs, the bond structure is like follows:
bond0 - slaver0(eth0) - agg0.lag_ports -> port0 - port1
\
port0
\
slaver1(eth1) - agg1.lag_ports -> NULL
\
port1
If we run 'ifenslave bond0 -d eth1', the process is like below:
excuting __bond_release_one()
|
bond_upper_dev_unlink()[step1]
| | |
| | bond_3ad_lacpdu_recv()
| | ->bond_3ad_rx_indication()
| | spin_lock_bh()
| | ->ad_rx_machine()
| | ->__record_pdu()[step2]
| | spin_unlock_bh()
| | |
| bond_3ad_state_machine_handler()
| spin_lock_bh()
| ->ad_port_selection_logic()
| ->try to find free aggregator[step3]
| ->try to find suitable aggregator[step4]
| ->did not find a suitable aggregator[step5]
| spin_unlock_bh()
| |
| |
bond_3ad_unbind_slave() |
spin_lock_bh()
spin_unlock_bh()
step1: already removed slaver1(eth1) from list, but port1 remains
step2: receive a lacpdu and update port0
step3: port0 will be removed from agg0.lag_ports. The struct is
"agg0.lag_ports -> port1" now, and agg0 is not free. At the
same time, slaver1/agg1 has been removed from the list by step1.
So we can't find a free aggregator now.
step4: can't find suitable aggregator because of step2
step5: cause a calltrace since port->aggregator is NULL
To solve this concurrency problem, put bond_upper_dev_unlink()
after bond_3ad_unbind_slave(). In this way, we can invalid the port
first and skip this port in bond_3ad_state_machine_handler(). This
eliminates the situation that the slaver has been removed from the
list but the port is still valid.

2.30.2
From: Kuogee Hsieh <[email protected]>
[ Upstream commit 2e0adc765d884cc080baa501e250bfad97035b09 ]
Initialize both pre-emphasis and voltage swing level to 0 before
start link training and do not end link training until video is
ready to reduce the period between end of link training and video
start to meet Link Layer CTS requirement. Some dongle main link
symbol may become unlocked again if host did not end link training
soon enough after completion of link training 2. Host have to re
train main link if loss of symbol locked detected before end link
training so that the coming video stream can be transmitted to sink
properly. This fixes Link Layer CTS cases 4.3.2.1, 4.3.2.2, 4.3.2.3
and 4.3.2.4.
Changes in v3:
-- merge retrain link if loss of symbol locked happen into this patch
-- replace dp_ctrl_loss_symbol_lock() with dp_ctrl_channel_eq_ok()

[ Upstream commit 70e740ad55e5f93a19493720f4105555fade4a73 ]
The configuration of USB VBUS regulators was borrowed from downstream
kernel, which is incorrect because the corresponding GPIOs are connected
to PROX_EN (A501 3G model) and LED_EN pins in accordance to the board
schematics. USB works fine with both GPIOs being disabled, so remove the
bogus USB VBUS regulators. The USB VBUS of USB3 is supplied from the fixed
5v system regulator and device-mode USB1 doesn't have VBUS switches.

[ Upstream commit a211260c34cfadc6068fece8c9e99e0fe1e2a2b6 ]
The variable val is declared without initialization, and its address is
passed to amdgpu_i2c_get_byte(). In this function, the value of val is
accessed in:
DRM_DEBUG("i2c 0x%02x 0x%02x read failed\n",
addr, *val);
Also, when amdgpu_i2c_get_byte() returns, val may remain uninitialized,
but it is accessed in:
val &= ~amdgpu_connector->router.ddc_mux_control_pin;
To fix this possible uninitialized-variable access, initialize val to 0 in
amdgpu_i2c_router_select_ddc_port().

The variable dc->clk_mgr is checked in:
if (dc->clk_mgr && dc->clk_mgr->funcs->get_clock)
This indicates dc->clk_mgr can be NULL.
However, it is dereferenced in:

To fix this null-pointer dereference, check dc->clk_mgr and the function
pointer dc->clk_mgr->funcs->get_clock earlier, and return if one of them
is NULL.

aborted on SCIF serial consoles:
- a NUL character remains in the RX queue after a break has been detected,
which is then passed on to uart_handle_sysrq_char()
- the break interrupt is handled twice on controllers with multiplexed ERI

[ Upstream commit e7006de6c23803799be000a5dcce4d916a36541a ]
We cannot detect a (perhaps buggy) controller that is sending us
a completion for a request that was already completed (for example
sending a completion twice), this phenomenon was seen in the wild
a few times.
So to protect against this, we use the upper 4 msbits of the nvme sqe
command_id to use as a 4-bit generation counter and verify it matches
the existing request generation that is incrementing on every execution.
The 16-bit command_id structure now is constructed by:
| xxxx | xxxxxxxxxxxx |
gen request tag
This means that we are giving up some possible queue depth as 12 bits
allow for a maximum queue depth of 4095 instead of 65536, however we
never create such long queues anyways so no real harm done.

From: Darrick J. Wong <[email protected]>
[ Upstream commit b69eea82d37d9ee7cfb3bf05103549dd4ed5ffc3 ]
Modern-day mapping_set_error has the ability to squash the usual
negative error code into something appropriate for long-term storage in
a struct address_space -- ENOSPC becomes AS_ENOSPC, and everything else
becomes EIO. iomap squashes /everything/ to EIO, just as XFS did before
that, but this doesn't make sense.
Fix this by making it so that we can pass ENOSPC to userspace when
writeback fails due to space problems.

Current flow will lead to null ptr access because of trying
to get the size of freed probe-request packets. We store the
information of packet size into rsvd page instead and also fix
the size error issue, which will cause unstable behavoir of
sending probe request by wow firmware.

The problem is that the original code is trying to copy data into a
couple of struct members adjacent to each other in a single call to
memcpy(). So, the compiler legitimately complains about it. As these
are just a couple of members, fix this by copying each one of them in
separate calls to memcpy().
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

[why]
The units of the time_per_pixel variable were incorrect, this had to be
changed for the code to properly function.
[how]
The change was very straightforward, only required one line of code to

When the VP8 decoders can't find a reference frame,
the driver falls back to the current output frame.
This will probably produce some undesirable results,
leading to frame corruption, but shouldn't cause
noisy warnings.

From: Jack Pham <[email protected]>
[ Upstream commit bcacbf06c891374e7fdd7b72d11cda03b0269b43 ]
Currently the composite driver encodes the MaxPower field of
the configuration descriptor by reading the c->MaxPower of the
usb_configuration only if it is non-zero, otherwise it falls back
to using the value hard-coded in CONFIG_USB_GADGET_VBUS_DRAW.
However, there are cases when a configuration must explicitly set
bMaxPower to 0, particularly if its bmAttributes also has the
Self-Powered bit set, which is a valid combination.
This is specifically called out in the USB PD specification section
9.1, in which a PDUSB device "shall report zero in the bMaxPower
field after negotiating a mutually agreeable Contract", and also
verified by the USB Type-C Functional Test TD.4.10.2 Sink Power
Precedence Test.
The fix allows the c->MaxPower to be used for encoding the bMaxPower
even if it is 0, if the self-powered bit is also set. An example
usage of this would be for a ConfigFS gadget to be dynamically
updated by userspace when the Type-C connection is determined to be
operating in Power Delivery mode.

When insmod zynqmp-dpsub.ko after rmmod it, system will hang with the
error log as below:

[ 94.023404] Console: switching to colour dummy device 80x25
root@xilinx-zynqmp:~# insmod zynqmp-dpsub.ko
<hang here>
This is because that in zynqmp_dp_probe it tries to access some DP
registers while the DP controller is still in the reset state. When
running "rmmod zynqmp_dpsub", zynqmp_dp_reset(dp, true) in
zynqmp_dp_phy_exit is called to force the DP controller into the reset
state. Then insmod will call zynqmp_dp_probe to program the DP registers,
but at this moment the DP controller hasn't been brought out of the reset
state yet since the function zynqmp_dp_reset(dp, false) is called later and
this will result the system hang.
Releasing the reset to DP controller before any read/write operation to it
will fix this issue. And for symmetry, move zynqmp_dp_reset() call from
zynqmp_dp_phy_exit() to zynqmp_dp_remove().

[ Upstream commit 95413846cca37f20000dd095cf6d91f8777129d7 ]
The program type cannot be deduced from 'tx' which causes an invalid
argument error when trying to load xdp_tx.o using the skeleton.
Rename the section name to "xdp" so that libbpf can deduce the type.

[ Upstream commit 3736127a3aa805602b7a2ad60ec9cfce68065fbb ]
Function btrfs_lookup_data_extent calls btrfs_search_slot to verify if
the EXTENT_ITEM exists in the extent tree. btrfs_search_slot can return
values bellow zero if an error happened.
Function replay_one_extent currently checks if the search found
something (0 returned) and increments the reference, and if not, it
seems to evaluate as 'not found'.
Fix the condition by checking if the value was bellow zero and return
early.

Sometimes kernel is trying to probe Fingerprint MCU (FPMCU) when it
hasn't initialized SPI yet. This can happen because FPMCU is restarted
during system boot and kernel can send message in short window
eg. between sysjump to RW and SPI initialization.

This is because in cipso_v4_doi_free() there is no check
on 'doi_def->map.std' when 'doi_def->type' equal 1, which
is possibe, since netlbl_cipsov4_add_std() haven't initialize
it before alloc 'doi_def->map.std'.
This patch just add the check to prevent panic happen for similar

abs() returns signed long, which could not convert the type
as unsigned, and it may cause a mismatch type warning from
static tools. To fix it, this patch uses an variable to save
the abs()'s result and does a explicit conversion.

From: Johannes Berg <[email protected]>
[ Upstream commit c6ce1c74ef2923b8ffd85f7f8b486f804f343b39 ]
When TVQM is enabled (iwl_mvm_has_new_tx_api() is true), then
queue numbers are just sequentially assigned 0, 1, 2, ...
Prior to TVQM, in DQA, there were some statically allocated
queue numbers:
* IWL_MVM_DQA_AUX_QUEUE == 1,
* both IWL_MVM_DQA_INJECT_MONITOR_QUEUE and
IWL_MVM_DQA_P2P_DEVICE_QUEUE == 2, and
* IWL_MVM_DQA_AP_PROBE_RESP_QUEUE == 9.
Now, these values are assigned to the members mvm->aux_queue,
mvm->snif_queue, mvm->probe_queue and mvm->p2p_dev_queue by
default. Normally, this doesn't really matter, and if TVQM is
in fact available we override them to the real values after
allocating a queue for use there.
However, this allocation doesn't always happen. For example,
for mvm->p2p_dev_queue (== 2) it only happens when the P2P
Device interface is started, if any. If it's not started, the
value in mvm->p2p_dev_queue remains 2. This wouldn't really
matter all that much if it weren't for iwl_mvm_is_static_queue()
which checks a queue number against one of those four static
numbers.
Now, if no P2P Device or monitor interface is added then queue
2 may be dynamically allocated, yet alias mvm->p2p_dev_queue or
mvm->snif_queue, and thus iwl_mvm_is_static_queue() erroneously
returns true for it. If it then gets full, all interface queues
are stopped, instead of just backpressuring against the one TXQ
that's really the only affected one.
This clearly can lead to issues, as everything is stopped even
if just a single TXQ filled its corresponding HW queue, if it
happens to have an appropriate number (2 or 9, AUX is always
reassigned.) Due to a mac80211 bug, this also led to a situation
in which the queues remained stopped across a deauthentication
and then attempts to connect to a new AP started failing, but
that's fixed separately.
Fix all of this by simply initializing the queue numbers to
the invalid value until they're used, if TVQM is enabled, and
also setting them back to that value when the queues are later
freed again.

We already have the option to attach a callback to an interrupt
to retrieve its pending state. As we are planning to expand this
facility, move this callback into its own data structure.
This will limit the size of individual interrupts as the ops
structures can be shared across multiple interrupts.

From: Thomas Zimmermann <[email protected]>
commit 147696720eca12ae48d020726208b9a61cdd80bc upstream.
Put the clock-selection code into each of the PLL-update functions to
make them select the correct pixel clock. Instead of copying the code,
introduce a new helper WREG_MISC_MASKED, which does masked writes into
<MISC>. Use it from each individual PLL update function.
The pixel clock for video output was not actually set before programming
the clock's values. It worked because the device had the correct clock
pre-set.
v2:
* don't duplicate <MISC> update code (Sam)

[ Upstream commit 7c75bde329d7e2a93cf86a5c15c61f96f1446cdc ]
If IRQ occurs between calling dsps_setup_optional_vbus_irq()
and dsps_create_musb_pdev(), then null pointer dereference occurs
since glue->musb wasn't initialized yet.
The patch puts initializing of neccesery data before registration
of the interrupt handler.

From: Zekun Shen <[email protected]>
[ Upstream commit 23151b9ae79e3bc4f6a0c4cd3a7f355f68dad128 ]
Bad header can have large length field which can cause OOB.
cptr is the last bytes for read, and the eeprom is parsed
from high to low address. The OOB, triggered by the condition
length > cptr could cause memory error with a read on
negative index.
There are some sanity check around length, but it is not
compared with cptr (the remaining bytes). Here, the
corrupted/bad EEPROM can cause panic.
I was able to reproduce the crash, but I cannot find the
log and the reproducer now. After I applied the patch, the
bug is no longer reproducible.

The check for count appears to be incorrect since a non-zero count
check occurs a couple of statements earlier. Currently the check is
always false and the dev->port->irq != PARPORT_IRQ_NONE part of the
check is never tested and the if statement is dead-code. Fix this
by removing the check on count.
Note that this code is pre-git history, so I can't find a sha for
it.

[ Upstream commit ea6942dad4b2a7e1735aa0f10f3d0b04b847750f ]
The power down sequence sets the link_up flag as false outside of the
mutex_lock. This is potentially unsafe.
In additional the flow in that sequence can be improved by first
testing if the link was powered, setting the link_up flag as false and
proceeding with the power down. In case the CPA bits cannot be
cleared, we only flag an error since we cannot deal with interrupts
any longer.

Previously, we noticed the one rpma example was failed[1] since commit
36f30e486dce ("IB/core: Improve ODP to use hmm_range_fault()"), where it
will use ODP feature to do RDMA WRITE between fsdax files.
After digging into the code, we found hmm_vma_handle_pte() will still
return EFAULT even though all the its requesting flags has been
fulfilled. That's because a DAX page will be marked as (_PAGE_SPECIAL |
PAGE_DEVMAP) by pte_mkdevmap().

commit 32d4f4b782bb8f0ceb78c6b5dc46eb577ae25bf7 upstream.
Commit f56ce412a59d ("mm: memcontrol: fix occasional OOMs due to
proportional memory.low reclaim") introduced a divide by zero corner
case when oomd is being used in combination with cgroup memory.low
protection.
When oomd decides to kill a cgroup, it will force the cgroup memory to
be reclaimed after killing the tasks, by writing to the memory.max file
for that cgroup, forcing the remaining page cache and reclaimable slab
to be reclaimed down to zero.
Previously, on cgroups with some memory.low protection that would result
in the memory being reclaimed down to the memory.low limit, or likely
not at all, having the page cache reclaimed asynchronously later.
With f56ce412a59d the oomd write to memory.max tries to reclaim all the
way down to zero, which may race with another reclaimer, to the point of
ending up with the divide by zero below.
This patch implements the obvious fix.

From: Masahiro Yamada <[email protected]>
commit 5f6e0fe01b6b33894cf6f61b359ab5a6d2b7674e upstream.
Commit 23243c1ace9f ("arch: use cross_compiling to check whether it is
a cross build or not") broke 64-bit parisc builds on 32-bit parisc
systems.
Helge mentioned:
- 64-bit parisc userspace is not supported yet [1]
- hppa gcc does not support "-m64" flag [2]
That means, parisc developers working on a 32-bit parisc machine need
to use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bit
parisc kernel.
After the offending commit, gcc is used in such a case because
both $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling is
unset.
A correct way is to introduce ARCH=parisc64 because building the 64-bit
parisc kernel on a 32-bit parisc system is not exactly a native build,
but rather a semi-cross build.

commit 5bccb945f38b2aff334619b23b50bb0a6a9995a5 upstream.
Add safe lut configuration for all the targets in dpu
driver as per QOS recommendation.
Issue reported on SC7280:
With wait-for-safe feature in smmu enabled, RT client
buffer levels are checked to be safe before smmu invalidation.
Since display was always set to unsafe it was delaying the
invalidaiton process thus impacting the performance on NRT clients
such as eMMC and NVMe.
Validated this change on SC7280, With this change eMMC performance
has improved significantly.
Changes in v2:
- Add fixes tag (Sai)
- CC stable kernel (Dimtry)
Changes in v3:
- Correct fixes tag with appropriate hash (stephen)
- Resend patch adding reviewed by tag
- Resend patch adding correct format for pushing into stable tree (Greg)
Fixes: 591e34a091d1 ("drm/msm/disp/dpu1: add support for display for SC7280 target")

[ Upstream commit e3faa49bcecdfcc80e94dd75709d6acb1a5d89f6 ]
Since the original TFO server code was implemented in commit
168a8f58059a22feb9e9a2dcc1b8053dbbbc12ef ("tcp: TCP Fast Open Server -
main code path") the TFO server code has supported the sysctl bit flag
TFO_SERVER_COOKIE_NOT_REQD. Currently, when the TFO_SERVER_ENABLE and
TFO_SERVER_COOKIE_NOT_REQD sysctl bit flags are set, a server connection
will accept a SYN with N bytes of data (N > 0) that has no TFO cookie,
create a new fast open connection, process the incoming data in the SYN,
and make the connection ready for accepting. After accepting, the
connection is ready for read()/recvmsg() to read the N bytes of data in
the SYN, ready for write()/sendmsg() calls and data transmissions to
transmit data.
This commit changes an edge case in this feature by changing this
behavior to apply to (N >= 0) bytes of data in the SYN rather than only
(N > 0) bytes of data in the SYN. Now, a server will accept a data-less
SYN without a TFO cookie if TFO_SERVER_COOKIE_NOT_REQD is set.
Caveat! While this enables a new kind of TFO (data-less empty-cookie
SYN), some firewall rules setup may not work if they assume such packets
are not legit TFOs and will filter them.

From: Halil Pasic <[email protected]>
commit 93ebb6828723b8aef114415c4dc3518342f7dcad upstream.
Since commit 903cd0f315fe ("swiotlb: Use is_swiotlb_force_bounce for
swiotlb data bouncing") if code sets swiotlb_force it needs to do so
before the swiotlb is initialised. Otherwise
io_tlb_default_mem->force_bounce will not get set to true, and devices
that use (the default) swiotlb will not bounce despite switolb_force
having the value of SWIOTLB_FORCE.
Let us restore swiotlb functionality for PV by fulfilling this new
requirement.
This change addresses what turned out to be a fragility in
commit 64e1f0c531d1 ("s390/mm: force swiotlb for protected
virtualization"), which ain't exactly broken in its original context,
but could give us some more headache if people backport the broken
change and forget this fix.

commit 13db8c50477d83ad3e3b9b0ae247e5cd833a7ae4 upstream.
After fork, the child process will get incorrect (2x) hugetlb_usage. If
a process uses 5 2MB hugetlb pages in an anonymous mapping,
HugetlbPages: 10240 kB
and then forks, the child will show,
HugetlbPages: 20480 kB
The reason for double the amount is because hugetlb_usage will be copied
from the parent and then increased when we copy page tables from parent
to child. Child will have 2x actual usage.
Fix this by adding hugetlb_count_init in mm_init.

commit fab827dbee8c2e06ca4ba000fa6c48bcf9054aba upstream.
Commit 5d097056c9a0 ("kmemcg: account certain kmem allocations to memcg")
enabled memcg accounting for pids allocated from init_pid_ns.pid_cachep,
but forgot to adjust the setting for nested pid namespaces. As a result,
pid memory is not accounted exactly where it is really needed, inside
memcg-limited containers with their own pid namespaces.
Pid was one the first kernel objects enabled for memcg accounting.
init_pid_ns.pid_cachep marked by SLAB_ACCOUNT and we can expect that any
new pids in the system are memcg-accounted.
Though recently I've noticed that it is wrong. nested pid namespaces
creates own slab caches for pid objects, nested pids have increased size
because contain id both for all parent and for own pid namespaces. The
problem is that these slab caches are _NOT_ marked by SLAB_ACCOUNT, as a
result any pids allocated in nested pid namespaces are not
memcg-accounted.
Pid struct in nested pid namespace consumes up to 500 bytes memory, 100000
such objects gives us up to ~50Mb unaccounted memory, this allow container
to exceed assigned memcg limits.

commit 81d0885d68ec427e62044cf46a400c9958ea0092 upstream.
tx_done is not used for napi_complete_done(). Thus, NAPI busy polling
mechanism by gro_flush_timeout and napi_defer_hard_irqs will not able
be triggered after a packet is transmitted when there is no receive
packet.
Fix this by taking the maximum value between tx_done and rx_done as
overall budget completed by the rxtx NAPI poll to ensure XDP Tx ZC
operation is continuously polling for next Tx frame. This gives
benefit of lower packet submission processing latency and jitter
under XDP Tx ZC mode.
Performance of tx-only using xdp-sock on Intel ADL-S platform is
the same with and without this patch.

[ Upstream commit 7c48662b9d56666219f526a71ace8c15e6e12f1f ]
The problem is that gpio_free() can sleep and the cfg_soc() can be
called with spinlocks held. One problematic call tree is:
--> ath_reset_internal() takes &sc->sc_pcu_lock spin lock
--> ath9k_hw_reset()
--> ath9k_hw_gpio_request_in()
--> ath9k_hw_gpio_request()
--> ath9k_hw_gpio_cfg_soc()
Remove gpio_free(), use error message instead, so we should make sure
there is no GPIO conflict.
Also remove ath9k_hw_gpio_free() from ath9k_hw_apply_gpio_override(),
as gpio_mask will never be set for SOC chips.

[ Upstream commit 6ac5720086c8b176794eb74c5cc09f8b79017f38 ]
When switching op-modes, or more generally when reconfiguring,
we might switch the RB size. In _iwl_pcie_rx_init() we have a
comment saying we must free all RBs since we might switch the
size, but this is actually too late: the switch has been done
and we'll free the buffers with the wrong size.
Fix this by always freeing the buffers, if any, at the start
of configure, instead of only after the size may have changed.

[ Upstream commit 1ec06c2dee679e9f089e78ed20cb74ee90155f61 ]
On systems with multiple SH per SE compute_static_thread_mgmt_se#
is split into independent masks, one for each SH, in the upper and
lower 16 bits. We need to detect this and apply cu masking to each
SH. The cu mask bits are assigned first to each SE, then to
alternate SHs, then finally to higher CU id. This ensures that
the maximum number of SPIs are engaged as early as possible while
balancing CU assignment to each SH.
v2: Use max SH/SE rather than max SH in cu_per_sh.
v3: Fix comment blocks, ensure se_mask is initially zero filled,
and correctly assign se.sh.cu positions to unset bits in cu_mask.

commit c8fadf019964d0eb1da410ba8b629494d3339db9 upstream.
The first invocation of function find_first_zero_bit will return 0 and
queue_id gets set to 0.
An index of queue_pair_map also gets set to 0.
qpair_id = find_first_zero_bit(ha->qpair_qid_map, ha->max_qpairs);
set_bit(qpair_id, ha->qpair_qid_map);
ha->queue_pair_map[qpair_id] = qpair;
In the alloc_queue callback driver checks the map, if queue is already
allocated:
ha->queue_pair_map[qidx]
This works fine as long as max_qpairs is greater than nvme_max_hw_queues(8)
since the size of the queue_pair_map is equal to max_qpair. In case nr_cpus
is less than 8, max_qpairs is less than 8. This creates wrong value
returned as qpair.

commit 11e4b63abbe23872b45f325a7c6c8b7f9ff42cad upstream.
The standard printk() tries to flush the message to the console
immediately. It tries to take the console lock. If the lock is
already taken then the current owner is responsible for flushing
even the new message.
There is a small race window between checking whether a new message is
available and releasing the console lock. It is solved by re-checking
the state after releasing the console lock. If the check is positive
then console_unlock() tries to take the lock again and process the new
message as well.
The commit 996e966640ddea7b535c ("printk: remove logbuf_lock") causes that
console_seq is not longer read atomically. As a result, the re-check might
be done with an inconsistent 64-bit index.
Solve it by using the last sequence number that has been checked under
the console lock. In the worst case, it will take the lock again only
to realized that the new message has already been proceed. But it
was possible even before.
The variable next_seq is marked as __maybe_unused to call down compiler
warning when CONFIG_PRINTK is not defined.

commit a052096bdd6809eeab809202726634d1ac975aa1 upstream.
The cpu hotplug notifiers are called without updating the core/thread
masks when a new CPU is added. This causes problems with code setting
up data structures in a cpu hotplug notifier, and relying on that later
in normal code.
This caused a crash in the new core scheduling code (SCHED_CORE),
where rq->core was set up in a notifier depending on cpu masks.
To fix this, add a cpu_setup_mask which is used in update_cpu_masks()
instead of the cpu_online_mask to determine whether the cpu masks should
be set for a certain cpu. Also move update_cpu_masks() to update the
masks before calling notify_cpu_starting() so that the notifiers are
seeing the updated masks.

From: Alyssa Rosenzweig <[email protected]>
commit b5fab345654c603c07525100d744498f28786929 upstream.
In lock_region, simplify the calculation of the region_width parameter.
This field is the size, but encoded as ceil(log2(size)) - 1.
ceil(log2(size)) may be computed directly as fls(size - 1). However, we
want to use the 64-bit versions as the amount to lock can exceed
32-bits.
This avoids undefined (and completely wrong) behaviour when locking all
memory (size ~0). In this case, the old code would "round up" ~0 to the
nearest page, overflowing to 0. Since fls(0) == 0, this would calculate
a region width of 10 + 0 = 10. But then the code would shift by
(region_width - 11) = -1. As shifting by a negative number is undefined,
UBSAN flags the bug. Of course, even if it were defined the behaviour is
wrong, instead of locking all memory almost none would get locked.
The new form of the calculation corrects this special case and avoids
the undefined behaviour.

-------------------
Since this test will be scheduled by 0Day to a random host that could have
only a few cpus(2-8), enlarge the timeout to avoid a false NG report.
In practice, i tried to pin it to only one cpu by 'taskset 0x01 ./test_maps',
and knew 10S is likely enough, but i still perfer to a larger value 30.

2.30.2
From: Juhee Kang <[email protected]>
[ Upstream commit c0e9422c4e6ca9abd4bd6e1598400c7231eb600b ]
Currently, most pktgen samples print the execution result when the
program is terminated normally. However, sample03 doesn't work
appropriately.
This is results of samples:
# DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 1
Running... ctrl^C to stop
Device: eth0@0
Result: OK: 19(c5+d13) usec, 1 (60byte,0frags)
51762pps 24Mb/sec (24845760bps) errors: 0
# DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample03_burst_single_flow.sh -n 1
Running... ctrl^C to stop
The reason why it doesn't print the execution result when the program is
terminated usually is that sample03 doesn't call the function which
prints the result, unlike other samples.
So, this commit solves this issue by calling the function before
termination. Also, this commit changes control_c function to
print_result to maintain consistency with other samples.

From: Alyssa Rosenzweig <[email protected]>
commit bd7ffbc3ca12629aeb66fb9e28cf42b7f37e3e3b upstream.
When locking a region, we currently clamp to a PAGE_SIZE as the minimum
lock region. While this is valid for Midgard, it is invalid for Bifrost,
where the minimum locking size is 8x larger than the 4k page size. Add a
hardware definition for the minimum lock region size (corresponding to
KBASE_LOCK_REGION_MIN_SIZE_LOG2 in kbase) and respect it.

[ Upstream commit b16ac5bf732a5e23d164cf908ec7742d6a6120d3 ]
libbpf CI has reported send_signal test is flaky although
I am not able to reproduce it in my local environment.
But I am able to reproduce with on-demand libbpf CI ([1]).
Through code analysis, the following is possible reason.
The failed subtest runs bpf program in softirq environment.
Since bpf_send_signal() only sends to a fork of "test_progs"
process. If the underlying current task is
not "test_progs", bpf_send_signal() will not be triggered
and the subtest will fail.
To reduce the chances where the underlying process is not
the intended one, this patch boosted scheduling priority to
-20 (highest allowed by setpriority() call). And I did
10 runs with on-demand libbpf CI with this patch and I
didn't observe any failures.

SD standard speed timing was met only at 19MHz and not 25 MHz, that's
why changing driver to 19MHz. The reason for this is when a level shifter
is used on the board, timing was met for standard speed only at 19MHz.
Since this level shifter is commonly required for high speed modes,
the driver is modified to use standard speed of 19Mhz.

As far as I can tell, this is a bug with the m68kmmu architecture, not
with my driver:
The CONFIG_ISA_DMA_API option is provided for coldfire, which implements it,
but dragonball also sets the option as a side-effect, without actually
implementing
the interfaces. The patch below should fix it.

commit a77b58825d7221d4a45c47881c35a47ba003aa73 upstream.
Mali virtual addresses are 48-bit. Use a u64 instead of size_t to ensure
we can express the "lock everything" condition as ~0ULL without
overflow. This code was silently broken on any platform where a size_t
is less than 48-bits; in particular, it was broken on 32-bit armv7
platforms which remain in use with panfrost. (Mainly RK3288)

[ Upstream commit e72a55f2e5ddcfb3dce0701caf925ce435b87682 ]
When a read/write command is sent via ioctl to the kernel,
and the command fails, the actual error response of the emmc
is not sent to the user.
IOCTL read/write tests are carried out using commands
17 (Single BLock Read), 24 (Single Block Write),
18 (Multi Block Read), 25 (Multi Block Write)
The tests are carried out on a 64Gb emmc device. All of these
tests try to access an "out of range" sector address (0x09B2FFFF).
It is seen that without the patch the response received by the user
is not OUT_OF_RANGE error (R1 response 31st bit is not set) as per
JEDEC specification. After applying the patch proper response is seen.
This is because the function returns without copying the response to
the user in case of failure. This patch fixes the issue.
Hence, this memcpy is required whether we get an error response or not.
Therefor it is moved up from the current position up to immediately
after we have called mmc_wait_for_req().
The test code and the output of only the CMD17 is included in the
commit to limit the message length.
CMD17 (Test Code Snippet):
==========================
printf("Forming CMD%d\n", opt_idx);
/* single block read */
cmd.blksz = 512;
cmd.blocks = 1;
cmd.write_flag = 0;
cmd.opcode = 17;
//cmd.arg = atoi(argv[3]);
cmd.arg = 0x09B2FFFF;
/* Expecting response R1B */
cmd.flags = MMC_RSP_SPI_R1 | MMC_RSP_R1 | MMC_CMD_ADTC;
memset(data, 0, sizeof(__u8) * 512);
mmc_ioc_cmd_set_data(cmd, data);
printf("Sending CMD%d: ARG[0x%08x]\n", opt_idx, cmd.arg);
if(ioctl(fd, MMC_IOC_CMD, &cmd))
perror("Error");
printf("\nResponse: %08x\n", cmd.response[0]);
CMD17 (Output without patch):
=============================
test@test-LIVA-Z:~$ sudo ./mmc cmd_test /dev/mmcblk0 17
Entering the do_mmc_commands:Device: /dev/mmcblk0 nargs:4
Entering the do_mmc_commands:Device: /dev/mmcblk0 options[17, 0x09B2FFF]

In skip_account(), test->skip_cnt is set to 0 at the end, this makes next print
statement never display SKIP status for the subtest. This patch moves the
accounting logic after the print statement, fixing the issue.
This patch also added SKIP status display for normal tests.

From: Thomas Hebb <[email protected]>
[ Upstream commit 3ac5e45291f3f0d699a721357380d4593bc2dcb3 ]
For unexplained reasons, the prescaler register for this device needs to
be cleared (set to 1) while performing a data read or else the command
will hang. This does not appear to affect the real clock rate sent out
on the bus, so I assume it's purely to work around a hardware bug.
During normal operation, the prescaler is already set to 1, so nothing
needs to be done. However, in "initial mode" (which is used for sub-MHz
clock speeds, like the core sets while enumerating cards), it's set to
128 and so we need to reset it during data reads. We currently fail to
do this for long reads.
This has no functional affect on the driver's operation currently
written, as the MMC core always sets a clock above 1MHz before
attempting any long reads. However, the core could conceivably set any
clock speed at any time and the driver should still work, so I think
this fix is worthwhile.
I personally encountered this issue while performing data recovery on an
external chip. My connections had poor signal integrity, so I modified
the core code to reduce the clock speed. Without this change, I saw the
card enumerate but was unable to actually read any data.
Writes don't seem to work in the situation described above even with
this change (and even if the workaround is extended to encompass data
write commands). I was not able to find a way to get them working.

As I replied to Sasha earlier, I don't see a good reason to backport
this, as it doesn't improve anything on its own. Unless there is a
compelling reason to get this backported, I'd rather see it dropped.

Yes, I'll drop it. I originally brought it as a dependency for a patch
