[ Upstream commit 37f62c0d5822f631b786b29a1b1069ab714d1a28 ]
This is done in order not to trig the below warning in
ieee80211_rx_napi:
WARN_ON_ONCE(softirq_count() == 0);
ieee80211_rx_napi requires that softirq's are disabled during
execution.
The High latency bus drivers (SDIO and USB) sometimes call the wmi
ep_rx_complete callback from non softirq context, resulting in a trigger
of the above warning.
Calling ieee80211_rx_ni with softirq's already disabled (e.g., from
softirq context) should be safe as the local_bh_disable and
local_bh_enable functions (called from ieee80211_rx_ni) are fully
reentrant.

commit 8a38dacf87180738d42b058334c951eba15d2d47 upstream.
The Ethernet Switch core mask was set to 0, causing the switch core to
be not reset on BCM6368 on boot. Provide the proper mask so the switch
core gets reset to a known good state.
Fixes: 799faa626c71 ("MIPS: BCM63XX: add core reset helper")

[ Upstream commit f9d08f1e1939ad4d92e38bd3dee6842512f5bee6 ]
While registering a mad agent, a user space can trigger various errors
and flood the logs.
Therefore, decrease verbosity and rate limit such error messages.
While we are at it, use __func__ to print function name.

[ Upstream commit 142a9c287613560edf5a03c8d142c8b6ebc1995b ]
It is illegal to change MTU to a value lower than the minimum MTU
stated in ethernet spec. In addition to that we need to add 4 bytes
for encapsulation header (IPOIB_ENCAP_LEN).
Before "ifconfig ib0 mtu 0" command, succeeds while it obviously shouldn't.

Playback of 44.1Khz contents with HDMI plugged returns
"Invalid pipe config" because HDMI paths in the FW

This patch filters out sampling rates not supported

Tx99 is typically configured via a monitor mode interface, which does
not get added to the driver as a vif. Since the code currently expects
a configured virtual interface for tx99, enabling tx99 via debugfs fails.
Since the vif is not needed anyway, remove all checks for it.

Vendor defined U-Boot has changed the partition scheme a while ago:
* kernel partition 6MB
* file system partition uses the remainder up to end of the NAND
* increased size of the environment partition (to get an OneNAND compatible base address)
* shrink the U-Boot partition
Let's be compatible (e.g. Debian kernel built from upstream).

If the CPU DAI does not initialise rate_max, say if using
using KNOT or CONTINUOUS, then the rate_max field will be
initialised to 0. A value of zero in the rate_max field of
the hardware runtime will cause the sound card to support no
sample rates at all. Obviously this is not desired, just a
different mechanism is being used to apply the constraints. As
such update the setting of rate_max in dpcm_init_runtime_hw
to be consistent with the non-DPCM cases and set rate_max to
UINT_MAX if nothing is defined on the CPU DAI.

make the existing USB power GPIO code generic and use that.

2.20.1
From: Marek Szyprowski <[email protected]>
[ Upstream commit f8f3b7fc21b1cb59385b780acd9b9a26d04cb7b2 ]
Regulators, which are marked as 'on-in-suspend' seems to be critical for
board operation, thus they must not be disabled anytime. This can be
only assured by marking them as 'always-on', because otherwise some
actions of their clients might result in turning them off. This patch
restores suspend/resume operation on Peach-Pit Chromebook board. It
partially reverts 'always-on' property removal done by the commit
mentioned in the Fixes tag.
Fixes: 665c441eea3d ("ARM: dts: exynos: Remove unneded always-on for regulators on Peach boards")

include/trace/events/sched.h includes <linux/sched.h> (via
<linux/sched/numa_balancing.h>) and so knows about the TASK_* constants
used to interpret .prev_state. So instead of duplicating the magic
numbers make use of the defined macros to ease understanding the
mapping from state bits to letters which isn't completely intuitive for
an outsider.

The VIDEO_GET_EVENT and VIDEO_STILLPICTURE was added back in 2005 but
it never worked because the command number is wrong.
Using the right command number means we have a better chance of them
actually doing the right thing, though clearly nobody has ever tried
it successfully.
I noticed these while auditing the remaining users of compat_time_t
for y2038 bugs. This one is fine in that regard, it just never did
anything.

[ Upstream commit a993e0f583c7925adaa7721226ccd7a41e7e63d1 ]
In the DT binding, it is specified nowhere that 'vsc8531,vddmac' is an
u16, even though it's read as an u16 in the driver.
Let's update the driver to take into consideration that the
'vsc8531,vddmac' property is of the default type u32.

as same as other in-use kprobes.

hang. When firmware assertion happened, driver get notified with interrupt
vector updated in MPI configuration table. Then, the driver will read

There is no reason to block it here, kfree_rcu() should

regulator@b089000 unit address format error, expected "2089000"
The saw0 regulator reg value seems to be
copied and pasted from qcom-ipq8064.dtsi.
This patch fixes the reg value to match that of the
unit address which in turn silences the warning.
(There is no driver for qcom,saw2 right now.
So this went unnoticed)

From: Paolo Valente <[email protected]>
[ Upstream commit c8765de0adfcaaf4ffb2d951e07444f00ffa9453 ]
To reduce latency for interactive and soft real-time applications, bfq
privileges the bfq_queues containing the I/O of these
applications. These privileged queues, referred-to as weight-raised
queues, get a much higher share of the device throughput
w.r.t. non-privileged queues. To preserve this higher share, the I/O
of any non-weight-raised queue must be plugged whenever a sync
weight-raised queue, while being served, remains temporarily empty. To
attain this goal, bfq simply plugs any I/O (from any queue), if a sync
weight-raised queue remains empty while in service.
Unfortunately, this plugging typically lowers throughput with random
I/O, on devices with internal queueing (because it reduces the filling
level of the internal queues of the device).
This commit addresses this issue by restricting the cases where
plugging is performed: if a sync weight-raised queue remains empty
while in service, then I/O plugging is performed only if some of the
active bfq_queues are *not* weight-raised (which is actually the only
circumstance where plugging is needed to preserve the higher share of
the throughput of weight-raised queues). This restriction proved able
to boost throughput in really many use cases needing only maximum
throughput.

[ Upstream commit 83ef4fb7556b6a673f755da670cbacab7e2c7f1b ]
Func jz4780_dma_desc_residue() expects the index to the next hw
descriptor as its last parameter. Caller func jz4780_dma_tx_status(),
however, applied modulus before passing it. When the current hw
descriptor was last in the list, the index passed became zero.
The resulting excess of reported residue especially caused problems
with cyclic DMA transfer clients, i.e. ALSA AIC audio output, which
rely on this for determining current DMA location within buffer.
Combined with the recent and related residue-reporting fixes, spurious
ALSA audio underruns on jz4770 hardware are now fixed.

[ Upstream commit 4f36cb36c9d14340bb200d2ad9117b03ce992cfe ]
The GFS2_RDF_UPTODATE flag in the rgrp is used to determine when
a rgrp buffer is valid. It's cleared when the glock is invalidated,
signifying that the buffer data is now invalid. But before this
patch, function update_rgrp_lvb was setting the flag when it
determined it had a valid lvb. But that's an invalid assumption:
just because you have a valid lvb doesn't mean you have valid
buffers. After all, another node may have made the lvb valid,
and this node just fetched it from the glock via dlm.
Consider this scenario:
1. The file system is mounted with RGRPLVB option.
2. In gfs2_inplace_reserve it locks the rgrp glock EX, but thanks
to GL_SKIP, it skips the gfs2_rgrp_bh_get.
3. Since loops == 0 and the allocation target (ap->target) is
bigger than the largest known chunk of blocks in the rgrp
(rs->rs_rbm.rgd->rd_extfail_pt) it skips that rgrp and bypasses
the call to gfs2_rgrp_bh_get there as well.
4. update_rgrp_lvb sees the lvb MAGIC number is valid, so bypasses
gfs2_rgrp_bh_get, but it still sets sets GFS2_RDF_UPTODATE due
to this invalid assumption.
5. The next time update_rgrp_lvb is called, it sees the bit is set
and just returns 0, assuming both the lvb and rgrp are both
uptodate. But since this is a smaller allocation, or space has
been freed by another node, thus adjusting the lvb values,
it decides to use the rgrp for allocations, with invalid rd_free
due to the fact it was never updated.
This patch changes update_rgrp_lvb so it doesn't set the UPTODATE
flag anymore. That way, it has no choice but to fetch the latest
values.

On the error path of mxs_auart_request_gpio_irq() is performed
backward iterating with index i of enum type. Underline enum type
may be unsigned char. In this case check (--i >= 0) will be always
true and error handling goes into infinite loop.
The patch changes the check so that it is valid for signed and unsigned
types.

Commit d58e468b1112d ("flow_dissector: implements flow dissector BPF hook")
introduced struct bpf_flow_keys in include/uapi/linux/bpf.h and hence
caused the naming conflict with samples/bpf/sockex3_user.c.
The fix is to rename struct bpf_flow_keys in samples/bpf/sockex3_user.c
to flow_keys to avoid the conflict.

Sharing the same irqchip with multiple gpiochips is not a good
practice. For instance, when installing hooks, we change the state
of the irqchip. The initial state of the irqchip for the second
gpiochip to register is then disrupted.

If hv_synic_alloc() errors out, the state of the per-cpu context
for some CPUs is unknown since the zero'ing is done as each
CPU is iterated over. In such case, hv_synic_cleanup() may try to
free memory based on uninitialized values. Fix this by zero'ing
the per-cpu context for all CPUs before doing any memory
allocations that might fail.

The terminating NUL byte is only there because the buffer is
allocated with kzalloc(PAGE_SIZE, GFP_KERNEL), but since the
range-check is off-by-one, and PAGE_SIZE==PATH_MAX, the
returned string may not be zero-terminated if it is exactly
PATH_MAX characters long. Furthermore also the initial loop
may theoretically exceed PATH_MAX and cause a fault.

From: Peter Shih <[email protected]>
[ Upstream commit 00bca73bfca4fb0ab089b94cad0fc83d8b49c25f ]
Mediatek SPI driver modifies some fields (tx_buf, rx_buf, len, tx_dma,
rx_dma) of the spi_transfer* passed in when doing transfer_one and in
interrupt handler. This is somewhat unexpected, and there are some
caller (e.g. Cr50 spi driver) that reuse the spi_transfer for multiple
messages. Add a field to record how many bytes have been transferred,
and calculate the right len / buffer based on it instead.

Looking at logs from systems all over the place, it looks like tons
of broken systems exist that set the base address to zero. I can
only guess that is some sort of non-standard idea to mark the
interface as not being present. It can't be zero, anyway, so just
complain and ignore it.

From: Nathan Fontenot <[email protected]>
[ Upstream commit 85a88cabad57d26d826dd94ea34d3a785824d802 ]
When performing partition migrations all present CPUs must be online
as all present CPUs must make the H_JOIN call as part of the migration
process. Once all present CPUs make the H_JOIN call, one CPU is returned
to make the rtas call to perform the migration to the destination system.
During testing of migration and changing the SMT state we have found
instances where CPUs are offlined, as part of the SMT state change,
before they make the H_JOIN call. This results in a hung system where
every CPU is either in H_JOIN or offline.
To prevent this this patch disables CPU hotplug during the migration
process.

2.20.1
From: Felix Fietkau <[email protected]>
[ Upstream commit 6df0580be8bc30803c4d8b2ed9c2230a2740c795 ]
Various documented examples on how to set up tx99 with ath9k rely
on setting up a regular monitor interface for setting the channel.
My previous patch "ath9k: fix tx99 with monitor mode interface" made
it possible to set it up this way again. However, it was removing support
for using an active monitor interface, which is required for controlling
the bitrate as well, since the bitrate is not passed down with a regular
monitor interface.
This patch partially reverts the previous one, but keeps support for using
a regular monitor interface to keep documented steps working in cases
where the bitrate does not matter

[ Upstream commit bdae566d5d9733b6e32b378668b84eadf28a94d4 ]
During component_bind_all(), if bind() fails for any
particular component associated with a master, unbind()
should be called for all previous components in that
master's match array, whose bind() might have completed
successfully. As per the current logic, if bind() fails
for the component at position 'n' in the master's match
array, it would start calling unbind() from component in
'n'th position itself and work backwards, and will always
skip calling unbind() for component in 0th position in the
master's match array.
Fix this by updating the loop condition, and the logic to
refer to the components in master's match array, so that
unbind() is called for all components starting from 'n-1'st
position in the array, until (and including) component in
0th position.

[ Upstream commit a2df0984e73fd9e1dad5fc3f1c307ec3de395e30 ]
It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.
The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.

2.20.1
From: Julian Wiedmann <[email protected]>
[ Upstream commit 4d19db777a2f32c9b76f6fd517ed8960576cb43e ]
Calling napi_schedule() from process context does not ensure that the
NET_RX softirq is run in a timely fashion. So trigger it manually.
This is no big issue with current code. A call to ndo_open() is usually
followed by a ndo_set_rx_mode() call, and for qeth this contains a
spin_unlock_bh(). Except for OSN, where qeth_l2_set_rx_mode() bails out
early.
Nevertheless it's best to not depend on this behaviour, and just fix
the issue at its source like all other drivers do. For instance see
commit 83a0c6e58901 ("i40e: Invoke softirqs after napi_reschedule").

[ Upstream commit b860801e3237ec4c74cf8de0be4816996757ae5c ]
For non-VHE systems host kernel runs at EL1 and jumps to EL2 whenever
hypervisor code should be executed. In this case ETM4x driver must
restrict configuration to EL1 when it setups kernel tracing.
However, there is no separate hypervisor privilege level when VHE
is enabled, the host kernel runs at EL2.
This patch fixes configuration of TRCACATRn register for VHE systems
so that ETM_EXLEVEL_NS_HYP bit is used instead of ETM_EXLEVEL_NS_OS
to on/off kernel tracing. At the same time, it moves common code
to new helper.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

[ Upstream commit 32c7fbc8ffd752c6aa05d2dd7c13b0f0aa00ddaa ]
So far all the places calling hclge_tm_q_to_qs_map_cfg() are assigning
an u16 type value to "q_id", and in the processing of
hclge_tm_q_to_qs_map_cfg(), it also converts the "q_id" to le16.
The max tqp number for pf can be more than 256, we should use "u16" to
store the queue id, instead of "u8", which may cause data lost.

[ Upstream commit 23d9f5531c7c28546954b0bf332134a9b8a38c0a ]
NFP supports fairly enormous ring sizes (up to 256k descriptors).
In commit 466271703867 ("nfp: use kvcalloc() to allocate SW buffer
descriptor arrays") we have started using kvcalloc() functions to
make sure the allocation of software state arrays doesn't hit
the MAX_ORDER limit. Unfortunately, we can't use virtual mappings
for the DMA region holding HW descriptors. In case this allocation
fails instead of the generic (and fairly scary) warning/splat in
the logs print a helpful message explaining what happened and
suggesting how to fix it.

[ Upstream commit a9f36656b519a9a21309793c306941a3cd0eeb8f ]
With introduction of MC-aware mode to mlxsw, it became necessary to
configure TCs above 7 as well. There is now code in mlxsw to disable ETS
for these higher classes, but disablement of max shaper was neglected.
By default, max shaper is currently disabled to begin with, so the
problem is just cosmetic. However, for symmetry, do like we do for ETS
configuration, and call mlxsw_sp_port_ets_maxrate_set() for both TC i
and i + 8.

following commit:
commit d58e468b1112 ("flow_dissector: implements flow dissector BPF hook")
added struct bpf_flow_keys which conflicts with the struct with
same name in sockex2_kern.c and sockex3_kern.c
similar to commit:
commit 534e0e52bc23 ("samples/bpf: fix a compilation failure")
we tried the rename it "flow_keys" but it also conflicted with struct
having same name in include/net/flow_dissector.h. Hence renaming the
struct to "flow_key_record". Also, this commit doesn't fix the
compilation error completely because the similar struct is present in
sockex3_kern.c. Hence renaming it in both files sockex3_user.c and
sockex3_kern.c

From: Alex Williamson <[email protected]>
[ Upstream commit db04264fe9bc0f2b62e036629f9afb530324b693 ]
The SR-IOV spec requires that VFs must report zero for the INTx pin
register as VFs are precluded from INTx support. It's much easier for
the host kernel to understand whether a device is a VF and therefore
whether a non-zero pin register value is bogus than it is to do the
same in userspace. Override the INTx count for such devices and
virtualize the pin register to provide a consistent view of the device
to the user.
As this is clearly a spec violation, warn about it to support hardware
validation, but also provide a known whitelist as it doesn't do much
good to continue complaining if the hardware vendor doesn't plan to
fix it.

the DTS to just 3.0V because of the vmmc capability. This results in a
conflict from the mmc driver requesting an unsupportable voltage range
from 3.3V to 3.0V (min > max) as reported in dmesg. So, extend the
range up to 3.3V. The hw should be able to stand this 0.3V tolerance.
See mmc_regulator_set_vqmmc in drivers/mmc/core/core.c.
3.- The card detect signal is non-working. There is a known conflict
with jtag, but the workaround in drivers/soc/rockchip/grf.c does not
work. Adding the broken-cd attribute to the DTS fixes the issue.

From: Nava kishore Manne <[email protected]>
[ Upstream commit 4b9d33c6a30688344a3e95179654ea31b07f59b7 ]
The driver's suspend/resume functions were buggy.
If UART node contains any child node in the DT and
the child is established a communication path with
the parent UART. The relevant /dev/ttyPS* node will
be not available for other operations.
If the driver is trying to do any operations like
suspend/resume without checking the tty->dev status
it leads to the kernel crash/hang.
This patch fix this issue by call the device_may_wake()
with the generic parameter of type struct device.
in the uart suspend and resume paths.
It also fixes a race condition in the uart suspend
path(i.e uart_suspend_port() should be called at the
end of cdns_uart_suspend API this path updates the same)

[ Upstream commit 8dbf9c7abefd5c1434a956d5c6b25e11183061a3 ]
When USB requests for video data fail to be submitted, the driver
signals a problem to the host by halting the video streaming endpoint.
This is only valid in bulk mode, as isochronous transfers have no
handshake phase and can't thus report a stall. The usb_ep_set_halt()
call returns an error when using isochronous endpoints, which we happily
ignore, but some UDCs complain in the kernel log. Fix this by only
trying to halt the endpoint in bulk mode.

The IRQ is requested before the struct rtc is allocated and registered, but
this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.
Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
before requesting the IRQ.

The commit 391d4ee568b5 ("memfd: Fix locking when tagging pins")
introduces the following warning messages.
*WARNING: suspicious RCU usage in memfd_wait_for_pins*
It is because we still use radix_tree_deref_slot without read_rcu_lock.
We should use radix_tree_deref_slot_protected instead in the case.

[ Upstream commit 2893cc8ff892fa74972d8dc0e1d0dc65116daaa3 ]
Presently we check first if CPUID is enabled. If it is not already
enabled, then we next call identify_cpu_without_cpuid() and clear
X86_FEATURE_CPUID.
Unfortunately, identify_cpu_without_cpuid() is the function where CPUID
becomes _enabled_ on Cyrix 6x86/6x86L CPUs.
Reverse the calling sequence so that CPUID is first enabled, and then
check a second time to see if the feature has now been activated.

[ Upstream commit 79f25b10c9da3dbc953e47033d0494e51580ac3b ]
We can dump data from the firmware either when it crashes,
or when the firmware is alive.
Not all the data is available if the firmware is running
(like the Tx / Rx FIFOs which are available only when the
firmware is halted), so we first check that the firmware
is alive to compute the required size for the dump and then
fill the buffer with the data.
When we allocate the buffer, we test the STATUS_FW_ERROR
bit to check if the firmware is alive or not. This bit
can be changed during the course of the dump since it is
modified in the interrupt handler.
We hit a case where we allocate the buffer while the
firmware is sill working, and while we start to fill the
buffer, the firmware crashes. Then we test STATUS_FW_ERROR
again and decide to fill the buffer with data like the
FIFOs even if no room was allocated for this data in the
buffer. This means that we overflow the buffer that was
allocated leading to memory corruption.
To fix this, test the STATUS_FW_ERROR bit only once and
rely on local variables to check if we should dump fifos
or other firmware components.

[ Upstream commit 6b0e87a6aafe12d75c2bea6fc8e49e88b98b3083 ]
The SR_RST bit isn't latched. Hence, detecting a bus reset isn't reliable.
When it is detected, the right thing to do is to drop all connected and
disconnected commands. The code for that is already present so refactor it and
call it when SR_RST is set.

[ Upstream commit 45ddc1b24806cc8f1a09f23dd4e7b6e4a8ae36e1 ]
When NCR5380_abort() returns FAILED, the driver forgets that the target is
still busy. Hence, further commands may be sent to the target, which may fail
during selection and produce the error message, "reselection after won
arbitration?". Prevent this by leaving the busy flag set when NCR5380_abort()
fails.

[ Upstream commit 03b099bdcdf7125d4a63dc9ddeefdd454e05123d ]
There are comments in processor-cyrix.h advising you to _not_ make calls
using the deprecated macros in this style:
setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80);
This is because it expands the macro into a non-functioning calling
sequence. The calling order must be:
outb(CX86_CCR2, 0x22);
inb(0x23);
>From the comments:
* When using the old macros a line like
* setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
* gets expanded to:
* do {
* outb((CX86_CCR2), 0x22);
* outb((({
* outb((CX86_CCR2), 0x22);
* inb(0x23);
* }) | 0x88), 0x23);
* } while (0);
The new macros fix this problem, so use them instead.

[ Upstream commit 097f95d319f817e651bd51f8846aced92a55a6a1 ]
We configured iptables as below, which only allowed incoming data on
established connections:
iptables -t mangle -A PREROUTING -m state --state ESTABLISHED -j ACCEPT
iptables -t mangle -P PREROUTING DROP
When deleting a secondary address, current masquerade implements would
flush all conntracks on this device. All the established connections on
primary address also be deleted, then subsequent incoming data on the
connections would be dropped wrongly because it was identified as NEW
connection.
So when an address was delete, it should only flush connections related
with the address.

From: Stuart Hayes <[email protected]>
[ Upstream commit 6aecee6ad41cf97c0270f72da032c10eef025bf0 ]
The dell_rbu driver takes firmware update payloads and puts them in memory so
the system BIOS can find them after a reboot. This sometimes fails (though
rarely), because the memory containing the payload is in the CPU cache but
never gets written back to main memory before the system is rebooted (CPU
cache contents are lost on reboot).
With this patch, the payload memory will be changed to uncachable to ensure
that the payload is actually in main memory before the system is rebooted.

[ Upstream commit 32c850bf587f993b2620b91e5af8a64a7813f504 ]
If we went into sas_rediscover_dev() the attached_sas_addr was already insured
not to be zero. So it's unnecessary to check if the attached_sas_addr is zero.
And although if the sas address is not changed, we always have to unregister
the old device when we are going to register a new one. We cannot just leave
the device there and bring up the new.

[ Upstream commit e7753f3937610633a540f2be81be87531f96ff04 ]
>From the comment in the code, it claims the requirement for byte-address
alignment for RRP register: 'for 32-bit, 64-bit and 128-bit wide trace
memory, the four LSBs must be 0s. For 256-bit wide trace memory, the
five LSBs must be 0s'. This isn't consistent with the program, the
program sets five LSBs as zeros for 32/64/128-bit wide trace memory and
set six LSBs zeros for 256-bit wide trace memory.
After checking with the CoreSight Trace Memory Controller technical
reference manual (ARM DDI 0461B, section 3.3.4 RAM Read Pointer
Register), it proves the comment is right and the program does wrong
setting.
This patch fixes byte-address alignment for RRP by following correct
definition in the technical reference manual.

From: Suzuki K Poulose <[email protected]>
[ Upstream commit 5ecabe4a76e8cdb61fa3e24862d9ca240a1c4ddf ]
We create a coresight trace path for each online CPU when
we start the event. We rely on the number of online CPUs
and then go on to allocate an array matching the "number of
online CPUs" for holding the path and then uses normal
CPU id as the index to the array. This is problematic as
we could have some offline CPUs causing us to access beyond
the actual array size (e.g, on a dual SMP system, if CPU0 is
offline, CPU1 could be really accessing beyond the array).
The solution is to switch to per-cpu array for holding the path.

[ Upstream commit 070356513963be6196142acff56acc8359069fa1 ]
When sense data is valid, call set_driver_byte(cmd, DRIVER_SENSE). Otherwise
some callers of scsi_execute() will ignore sense data. Don't set DID_ERROR or
DID_RESET just because sense data is missing.

3. touch /mnt/file;
4. chown system /mnt/file; chgrp system /mnt/file;
5. xfs_io -f /mnt/file -c "fsync";
6. godown /mnt;
7. umount /mnt;
8. mount -t f2fs /dev/sdd /mnt;
After step 8) we will expect file's uid/gid are all system, but during
recovery, these two fields were not been recovered, fix it.

[ Upstream commit e00d93ac9a189673028ac125a74b9bc8ae73eebc ]
This re-applies commit b91c1e3e7a6f ("powerpc: Fix duplicate const
clang warning in user access code") (Jun 2015) which was undone in
commits:
f2ca80905929 ("powerpc/sparse: Constify the address pointer in __get_user_nosleep()") (Feb 2017)
d466f6c5cac1 ("powerpc/sparse: Constify the address pointer in __get_user_nocheck()") (Feb 2017)
f84ed59a612d ("powerpc/sparse: Constify the address pointer in __get_user_check()") (Feb 2017)
We see a large number of duplicate const errors in the user access
code when building with llvm/clang:
include/linux/pagemap.h:576:8: warning: duplicate 'const' declaration specifier [-Wduplicate-decl-specifier]
ret = __get_user(c, uaddr);
The problem is we are doing const __typeof__(*(ptr)), which will hit
the warning if ptr is marked const.
Removing const does not seem to have any effect on GCC code
generation.

The IRQ is requested before the struct rtc is allocated and registered, but
this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.
Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
before requesting the IRQ.

From: Qiuxu Zhuo <[email protected]>
[ Upstream commit dcc960b225ceb2bd66c45e0845d03e577f7010f9 ]
Users of the mce_register_decode_chain() are called for every logged
error. EDAC drivers should check:
1) Is this a memory error? [bit 7 in status register]
2) Is there a valid address? [bit 58 in status register]
3) Is the address a system address? [bitfield 8:6 in misc register]
The sb_edac driver performed test "1" twice. Waited far too long to
perform check "2". Didn't do check "3" at all.
Fix it by moving the test for valid address from
sbridge_mce_output_error() into sbridge_mce_check_error() and add a test
for the type immediately after. Delete the redundant check for the type
of the error from sbridge_mce_output_error().

[ Upstream commit 86b62e5cd8965d3056f9e9ccdec51631c37add81 ]
lpss_iosf_enter_d3_state() checks if all hw-blocks using the DMA
controllers are in d3 before powering down the DMA controllers.
But on devices, where the I2C bus connected to the PMIC is shared by
the PUNIT, the controller for that bus will never reach d3 since it has
an effectively empty _PS3 method. Instead it appears to automatically
power-down during S0i3 and we never see it as being in d3.
This causes the DMA controllers to never be powered-down on these devices,
causing them to never reach S0i3. This commit uses the ACPI _SEM method
to detect if an I2C bus is shared with the PUNIT and if it is, it removes
it from the mask of devices which lpss_iosf_enter_d3_state() checks for.
This fixes these devices never reaching any S0ix states.

From: Alan Modra <[email protected]>
[ Upstream commit 56d20861c027498b5a1112b4f9f05b56d906fdda ]
Call Frame Information is used by gdb for back-traces and inserting
breakpoints on function return for the "finish" command. This failed
when inside __kernel_clock_gettime. More concerning than difficulty
debugging is that CFI is also used by stack frame unwinding code to
implement exceptions. If you have an app that needs to handle
asynchronous exceptions for some reason, and you are unlucky enough to
get one inside the VDSO time functions, your app will crash.
What's wrong: There is control flow in __kernel_clock_gettime that
reaches label 99 without saving lr in r12. CFI info however is
interpreted by the unwinder without reference to control flow: It's a
simple matter of "Execute all the CFI opcodes up to the current
address". That means the unwinder thinks r12 contains the return
address at label 99. Disabuse it of that notion by resetting CFI for
the return address at label 99.
Note that the ".cfi_restore lr" could have gone anywhere from the
"mtlr r12" a few instructions earlier to the instruction at label 99.
I put the CFI as late as possible, because in general that's best
practice (and if possible grouped with other CFI in order to reduce
the number of CFI opcodes executed when unwinding). Using r12 as the
return address is perfectly fine after the "mtlr r12" since r12 on
that code path still contains the return address.
__get_datapage also has a CFI error. That function temporarily saves
lr in r0, and reflects that fact with ".cfi_register lr,r0". A later
use of r0 means the CFI at that point isn't correct, as r0 no longer
contains the return address. Fix that too.

The "has_config" variable is either uninitialized or true. The
"num_pins" variable is unsigned and we verified that it is non-zero on

just check "num_configs" directly and remove the "has_config" variable.

[ Upstream commit c71369de02b285d9da526a526d8f2affc7b17c59 ]
The coresight components could be operated either in sysfs mode or in perf
mode. For some of the components, the mode of operation doesn't matter as
they simply relay the data to the next component in the trace path. But for
sinks, they need to be able to provide the trace data back to the user.
Thus we need to make sure that "mode" is handled appropriately. e.g,
the sysfs mode could have multiple sources driving the trace data, while
perf mode doesn't allow sharing the sink.
The coresight_enable_sink() however doesn't really allow this check to
trigger as it skips the "enable_sink" callback if the component is
already enabled, irrespective of the mode. This could cause mixing
of data from different modes or even same mode (in perf), if the
sources are different. Also, if we fail to enable the sink while
enabling a path (where sink is the first component enabled),
we could end up in disabling the components in the "entire"
path which were not enabled in this trial, causing disruptions
in the existing trace paths.

[ Upstream commit 86989c41b5ea08776c450cb759592532314a4ed6 ]
If the first process started (aka /sbin/init) receives a SIGKILL it
will panic the system if it is delivered. Making the system unusable
and undebugable. It isn't much better if the first process started
receives SIGSTOP.
So always ignore SIGSTOP and SIGKILL sent to init.
This is done in a separate clause in sig_task_ignored as force_sig_info
can clear SIG_UNKILLABLE and this protection should work even then.

Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
the RX and TX path. These filtered channel can in theory still be used by
the hardware but the signal strength is reduced so much that it makes no
sense.
There is already a DT property to limit the available channels but ath10k
has to manually call this functionality to limit the currrently set wiphy
channels further.

[ Upstream commit 4a63c1ffd384ebdce40aac9c997dab68379137be ]
For userspace to tell the difference between an random signal
and an exception, the exception must include siginfo information.
Using SEND_SIG_FORCED for SIGSEGV is thus wrong, and it will result in
userspace seeing si_code == SI_USER (like a random signal) instead of
si_code == SI_KERNEL or a more specific si_code as all exceptions
deliver.
Therefore replace force_sig_info(SIGSEGV, SEND_SIG_FORCE, current)
with force_sig(SIG_SEGV, current) which gets this right and is shorter
and easier to type.

[ Upstream commit 030e46e495af855a13964a0aab9753ea82a96edc ]
When a read request is retried for the remaining partial
data, the response may restart from read response first
or read response only. So support those cases.
Do not advance the comp psn beyond the current wqe's last_psn
as that could skip over an entire read wqe and will cause the
req_retry() logic to set an incorrect req psn.
An example sequence is as follows:
Write PSN 40 -- this is the current WQE.
Read request PSN 41
Write PSN 42
Receive ACK PSN 42 -- this will complete the current WQE
for PSN 40, and set the comp psn to 42 which is a problem
because the read request at PSN 41 has been skipped over.
So when req_retry() tries to retransmit the read request,
it sets the req psn to 42 which is incorrect.
When retrying a read request, calculate the number of psns
completed based on the dma resid instead of the wqe first_psn.
The wqe first_psn could have moved if the read request was
retried multiple times.
Set the reth length to the dma resid to handle read retries for
the remaining partial data.

The clock controller registers are not 0x460 wide because the reset
controller starts at CBUS 0x4404. This currently overlaps with the
clock controller (which is at CBUS 0x4000).
There is no public documentation available on the actual size of the
clock controller's register area (also called "HHI"). However, in
Amlogic's GPL kernel sources the last "HHI" register is
HHI_HDMI_PHY_CNTL2 at CBUS + 0x43a8. 0x400 was chosen because that size
doesn't seem unlikely.

To prevent VF from deleting MAC address that was assigned by the
PF we need to check for that scenario when we try to delete a MAC
address from a VF.

commit 73ce9aec65b17433e18163d07eb5cb6bf114bd6c upstream.
IMC_MAX_PMU is used for static storage (per_nest_pmu_arr) which holds
nest pmu information. Current value for the macro is 32 based on
the initial number of nest pmu units supported by the nest microcode.
But going forward, microcode could support more nest units. Instead
of static storage, patch to fix the code to dynamically allocate an
array based on the number of nest imc units found in the device tree.

[ Upstream commit f7f9da89bc4f61e33f7b9f5c75c4efdc1f0455d8 ]
The clock controller registers are not 0x460 wide because the reset
controller starts at CBUS 0x4404. This currently overlaps with the
clock controller (which is at CBUS 0x4000).
There is no public documentation available on the actual size of the
clock controller's register area (also called "HHI"). However, in
Amlogic's GPL kernel sources the last "HHI" register is
HHI_HDMI_PHY_CNTL2 at CBUS + 0x43a8. 0x400 was chosen because that size
doesn't seem unlikely.

commit 762c69685ff7ad5ad7fee0656671e20a0c9c864d upstream.
We need to get the underlying dentry of parent; sure, absent the races
it is the parent of underlying dentry, but there's nothing to prevent
losing a timeslice to preemtion in the middle of evaluation of
lower_dentry->d_parent->d_inode, having another process move lower_dentry
around and have its (ex)parent not pinned anymore and freed on memory
pressure. Then we regain CPU and try to fetch ->d_inode from memory
that is freed by that point.
dentry->d_parent *is* stable here - it's an argument of ->lookup() and
we are guaranteed that it won't be moved anywhere until we feed it
to d_add/d_splice_alias. So we safely go that way to get to its
underlying dentry.

[ Upstream commit 55a3235fc71bf34303e34a95eeee235b2d2a35dd ]
For userspace to tell the difference between a random signal and an
exception, the exception must include siginfo information.
Using SEND_SIG_FORCED for SIGILL is thus wrong, and it will result
in userspace seeing si_code == SI_USER (like a random signal) instead
of si_code == SI_KERNEL or a more specific si_code as all exceptions
deliver.
Therefore replace force_sig_info(SIGILL, SEND_SIG_FORCE, current)
with force_sig(SIG_ILL, current) which gets this right and is
shorter and easier to type.

[ Upstream commit bd1d395070cca4f42a93e520b0597274789274a4 ]
When continuously running wifi up/down sequence, the napi poll
can be scheduled after the CE buffers being freed by ath10k_pci_flush
Steps:
In a certain condition, during wifi down below scenario might occur.
ath10k_stop->ath10k_hif_stop->napi_schedule->ath10k_pci_flush->napi_poll(napi_synchronize).
In the above scenario, CE buffer entries will be freed up and become NULL in
ath10k_pci_flush. And the napi_poll has been invoked after the flush process
and it will try to get the skb from the CE buffer entry and perform some action on that.
Since the CE buffer already cleaned by pci flush this action will create NULL
pointer dereference and trigger below kernel panic.
Unable to handle kernel NULL pointer dereference at virtual address 0000005c

After finding a reasonable gain, the function converts the configured
gain to a gain configuration option selector enum max9611_csa_gain.
Make the conversion clearly visible by using an explicit cast. This
also avoids a warning seen with clang:

commit e72b9dd6a5f17d0fb51f16f8685f3004361e83d0 upstream.
lower_dentry can't go from positive to negative (we have it pinned),
but it *can* go from negative to positive. So fetching ->d_inode
into a local variable, doing a blocking allocation, checking that
now ->d_inode is non-NULL and feeding the value we'd fetched
earlier to a function that won't accept NULL is not a good idea.

[ Upstream commit fd8133148eb6a733f9cfdaecd4d99f378e21d582 ]
The function of genphy_read_status is that reading phy information
from HW and using these information to update SW variable. If user
is using ethtool to setting the speed of phy and service task is calling
by hclge_get_mac_phy_link, the result of speed setting is uncertain.
Because ethtool cmd will modified phydev and hclge_get_mac_phy_link also
will modified phydev.
Because phy state machine will update phy link periodically, we can
just use phydev->link to check the link status. This patch removes
function call of genphy_read_status. To ensure accuracy, this patch
adds a phy state check. If phy state is not PHY_RUNNING, we consider
link is down. Because in some scenarios, phydev->link may be link up,
but phy state is not PHY_RUNNING. This is just an intermediate state.
In fact, the link is not ready yet.

[ Upstream commit 6b58859419554fb824e09cfdd73151a195473cbc ]
We observe an oops in the skx_edac module during boot:
EDAC MC0: Giving out device to module skx_edac controller Skylake Socket#0 IMC#0
EDAC MC1: Giving out device to module skx_edac controller Skylake Socket#0 IMC#1
EDAC MC2: Giving out device to module skx_edac controller Skylake Socket#1 IMC#0
...
EDAC MC13: Giving out device to module skx_edac controller Skylake Socket#0 IMC#1
EDAC MC14: Giving out device to module skx_edac controller Skylake Socket#1 IMC#0
EDAC MC15: Giving out device to module skx_edac controller Skylake Socket#1 IMC#1
Too many memory controllers: 16
EDAC MC: Removed device 0 for skx_edac Skylake Socket#0 IMC#0
We observe there are two memory controllers per socket, with a limit
of 16. Raise the maximum number of memory controllers from 16 to 2 *
MAX_NUMNODES (1024).
[ bp: This is just a band-aid fix until we've sorted out the whole issue
with the bus_type association and handling in EDAC and can get rid of
this arbitrary limit. ]

commit 003f01c780020daa9a06dea1db495b553a868c29 upstream.
The video buffer used by the queue is a vb2_v4l2_buffer, not a plain
vb2_buffer. Using the wrong type causes the allocation of the buffer
storage to be too small, causing a out of bounds write when
__init_vb2_v4l2_buffer initializes the buffer.

commit 167beb1756791e0806365a3f86a0da10d7a327ee upstream.
A check of the return value from get_cur_mix_raw() is missing at the
resolution test code in get_min_max_with_quirks(), which may leave the
variable untouched, leading to a random uninitialized value, as
detected by syzkaller fuzzer.
Add the missing return error check for fixing that.

When initializing the USB subsystem before starting the kernel,
OTG overcurrent detection is disabled. In case the OTG polarity of
overcurrent is low active, the overcurrent detection is never enabled
again and events cannot be reported as expected. Because imx usb
overcurrent polarity is low active by default, only detection needs
to be enable in usbmisc init function.

[ Upstream commit 6c7103aa026094a4ee2c2708ec6977a6dfc5331d ]
When runtime is not enabled, pm_runtime_get_sync() returns -EACCESS,
the counter will be incremented but the resume callback not called,
so enumeration and charging will not start properly.
To avoid that happen, disable irq on suspend and recheck on resume.
Practically this happens when the device is woken up from suspend by
plugging in usb.

We tried to revert commit d9c52fd17cb4 ("ath9k: fix tx99 with monitor
mode interface") but accidentally missed part of the locking change.
The lock has to be held earlier so that we're holding it when we do
"sc->tx99_vif = vif;" and also there in the current code there is a
stray unlock before we have taken the lock.
