Subject: [PATCH 5.15 62/72] drm/amdgpu: always reset the asic in suspend (v2)

From: Alex Deucher <[email protected]>

[ Upstream commit daf8de0874ab5b74b38a38726fdd3d07ef98a7ee ]

If the platform suspend happens to fail and the power rail
is not turned off, the GPU will be in an unknown state on
resume, so reset the asic so that it will be in a known
good state on resume even if the platform suspend failed.

v2: handle s0ix

Subject: [PATCH 5.15 32/72] md/raid1: fix missing bitmap update w/o WriteMostly devices

From: Song Liu <[email protected]>

commit 46669e8616c649c71c4cfcd712fd3d107e771380 upstream.

commit [1] causes missing bitmap updates when there isn't any WriteMostly
devices.

Detailed steps to reproduce by Norbert (which somehow didn't make to lore):

# setup md10 (raid1) with two drives (1 GByte sparse files)
dd if=/dev/zero of=disk1 bs=1024k seek=1024 count=0
dd if=/dev/zero of=disk2 bs=1024k seek=1024 count=0

losetup /dev/loop11 disk1
losetup /dev/loop12 disk2

mdadm --create /dev/md10 --level=1 --raid-devices=2 /dev/loop11 /dev/loop12

# add bitmap (aka write-intent log)
mdadm /dev/md10 --grow --bitmap=internal

echo check > /sys/block/md10/md/sync_action

root:# cat /sys/block/md10/md/mismatch_cnt
0
root:#

# remove member drive disk2 (loop12)
mdadm /dev/md10 -f loop12 ; mdadm /dev/md10 -r loop12

# modify degraded md device
dd if=/dev/urandom of=/dev/md10 bs=512 count=1

# no blocks recorded as out of sync on the remaining member disk1/loop11
root:# mdadm -X /dev/loop11 | grep Bitmap
Bitmap : 16 bits (chunks), 0 dirty (0.0%)
root:#

# re-add disk2, nothing synced because of empty bitmap
mdadm /dev/md10 --re-add /dev/loop12

# check integrity again
echo check > /sys/block/md10/md/sync_action

# disk1 and disk2 are no longer in sync, reads return differend data
root:# cat /sys/block/md10/md/mismatch_cnt
128
root:#

# clean up
mdadm -S /dev/md10
losetup -d /dev/loop11
losetup -d /dev/loop12
rm disk1 disk2

Fix this by moving the WriteMostly check to the if condition for
alloc_behind_master_bio().

From: Naveen N. Rao <[email protected]>

commit 823e670f7ed616d0ce993075c8afe0217885f79d upstream.

With the new osnoise tracer, we are seeing the below splat:

osnoise tracer on ppc64le is triggering osnoise_taint() for negative
duration in get_int_safe_duration() called from
trace_sched_switch_callback()->thread_exit().

The problem though is that the check for a valid trace_percpu_buffer is
incorrect in get_trace_buf(). The check is being done after calculating
the pointer for the current cpu, rather than on the main percpu pointer.
Fix the check to be against trace_percpu_buffer.

commit 4163cb3d1980383220ad7043002b930995dcba33 upstream.

This patch is not the full fix and still causes to call traces
during mlx5_ib_dereg_mr().

This reverts commit f0ae4afe3d35e67db042c58a52909e06262b740f.

Subject: [PATCH 5.15 06/72] ieee802154: atusb: fix uninit value in atusb_set_extended_addr

From: Pavel Skripkin <[email protected]>

commit 754e4382354f7908923a1949d8dc8d05f82f09cb upstream.

Alexander reported a use of uninitialized value in
atusb_set_extended_addr(), that is caused by reading 0 bytes via
usb_control_msg().

Fix it by validating if the number of bytes transferred is actually
correct, since usb_control_msg() may read less bytes, than was requested
by caller.

Fail log:

Subject: [PATCH 5.15 44/72] rndis_host: support Hytera digital radios

From: Thomas Toye <[email protected]>

commit 29262e1f773b4b6a43711120be564c57fca07cfb upstream.

Hytera makes a range of digital (DMR) radios. These radios can be
programmed to a allow a computer to control them over Ethernet over USB,
either using NCM or RNDIS.

This commit adds support for RNDIS for Hytera radios. I tested with a
Hytera PD785 and a Hytera MD785G. When these radios are programmed to
set up a Radio to PC Network using RNDIS, an USB interface will be added
with class 2 (Communications), subclass 2 (Abstract Modem Control) and
an interface protocol of 255 ("vendor specific" - lsusb even hints "MSFT
RNDIS?").

This patch is similar to the solution of this StackOverflow user, but
that only works for the Hytera MD785:
https://stackoverflow.com/a/53550858

To use the "Radio to PC Network" functionality of Hytera DMR radios, the
radios need to be programmed correctly in CPS (Hytera's Customer
Programming Software). "Forward to PC" should be checked in "Network"
(under "General Setting" in "Conventional") and the "USB Network
Communication Protocol" should be set to RNDIS.

Subject: [PATCH 5.15 49/72] drm/amdgpu: disable runpm if we are the primary adapter

From: Alex Deucher <[email protected]>

commit b95dc06af3e683d6b7ddbbae178b2b2a21ee8b2b upstream.

If we are the primary adapter (i.e., the one used by the firwmare
framebuffer), disable runtime pm. This fixes a regression caused
by commit 55285e21f045 which results in the displays waking up
shortly after they go to sleep due to the device coming out of
runtime suspend and sending a hotplug uevent.

Subject: [PATCH 5.15 50/72] power: bq25890: Enable continuous conversion for ADC at charging

From: Yauhen Kharuzhy <[email protected]>

commit 80211be1b9dec04cc2805d3d81e2091ecac289a1 upstream.

Instead of one shot run of ADC at beginning of charging, run continuous
conversion to ensure that all charging-related values are monitored
properly (input voltage, input current, themperature etc.).

From: Chunfeng Yun <[email protected]>

[ Upstream commit e3d4621c22f90c33321ae6a6baab60cdb8e5a77c ]

Use the Interval value from isoc/intr endpoint descriptor, no need
minus one. The original code doesn't cause transfer error for
normal cases, but it may have side effect with respond time of ERDY
or tPingTimeout.

From: Zekun Shen <[email protected]>

[ Upstream commit 5f50153288452e10b6edd69ec9112c49442b054a ]

The function obtain the next buffer without boundary check.
We should return with I/O error code.

The bug is found by fuzzing and the crash report is attached.
It is an OOB bug although reported as use-after-free.

Subject: [PATCH 5.15 58/72] ip6_vti: initialize __ip6_tnl_parm struct in vti6_siocdevprivate

From: William Zhao <[email protected]>

[ Upstream commit c1833c3964d5bd8c163bd4e01736a38bc473cb8a ]

The "__ip6_tnl_parm" struct was left uninitialized causing an invalid
load of random data when the "__ip6_tnl_parm" struct was used elsewhere.
As an example, in the function "ip6_tnl_xmit_ctl()", it tries to access
the "collect_md" member. With "__ip6_tnl_parm" being uninitialized and
containing random data, the UBSAN detected that "collect_md" held a
non-boolean value.

The UBSAN issue is as follows:

Subject: [PATCH 5.15 36/72] cgroup: Allocate cgroup_file_ctx for kernfs_open_file->priv

From: Tejun Heo <[email protected]>

commit 0d2b5955b36250a9428c832664f2079cbf723bec upstream.

of->priv is currently used by each interface file implementation to store
private information. This patch collects the current two private data usages
into struct cgroup_file_ctx which is allocated and freed by the common path.
This allows generic private data which applies to multiple files, which will
be used to in the following patch.

Note that cgroup_procs iterator is now embedded as procs.iter in the new
cgroup_file_ctx so that it doesn't need to be allocated and freed
separately.

v2: union dropped from cgroup_file_ctx and the procs iterator is embedded in
cgroup_file_ctx as suggested by Linus.

v3: Michal pointed out that cgroup1's procs pidlist uses of->priv too.
Converted. Didn't change to embedded allocation as cgroup1 pidlists get
stored for caching.

Subject: [PATCH 5.15 67/72] ipv6: raw: check passed optlen before reading

From: Tamir Duberstein <[email protected]>

[ Upstream commit fb7bc9204095090731430c8921f9e629740c110a ]

Add a check that the user-provided option is at least as long as the
number of bytes we intend to read. Before this patch we would blindly
read sizeof(int) bytes even in cases where the user passed
optlen<sizeof(int), which would potentially read garbage or fault.

Discovered by new tests in https://github.com/google/gvisor/pull/6957 .

The original get_user call predates history in the git repo.

Subject: [PATCH 5.15 38/72] Revert "i2c: core: support bus regulator controlling in adapter"

From: Wolfram Sang <[email protected]>

commit a19f75de73c220b4496d2aefb7a605dd032f7c01 upstream.

This largely reverts commit 5a7b95fb993ec399c8a685552aa6a8fc995c40bd. It
breaks suspend with AMD GPUs, and we couldn't incrementally fix it. So,
let's remove the code and go back to the drawing board. We keep the
header extension to not break drivers already populating the regulator.
We expect to re-add the code handling it soon.

Subject: [PATCH 5.15 37/72] cgroup: Use open-time cgroup namespace for process migration perm checks

From: Tejun Heo <[email protected]>

commit e57457641613fef0d147ede8bd6a3047df588b95 upstream.

cgroup process migration permission checks are performed at write time as
whether a given operation is allowed or not is dependent on the content of
the write - the PID. This currently uses current's cgroup namespace which is
a potential security weakness as it may allow scenarios where a less
privileged process tricks a more privileged one into writing into a fd that
it created.

This patch makes cgroup remember the cgroup namespace at the time of open
and uses it for migration permission checks instad of current's. Note that
this only applies to cgroup2 as cgroup1 doesn't have namespace support.

This also fixes a use-after-free bug on cgroupns reported in

https://lore.kernel.org/r/[email protected]

Note that backporting this fix also requires the preceding patch.

From: Jedrzej Jagielski <[email protected]>

commit e738451d78b2f8a9635d66c6a87f304b4d965f7a upstream.

There was a wrong queues representation in sysfs during
driver's reinitialization in case of online cpus number is
less than combined queues. It was caused by stopped
NetworkManager, which is responsible for calling vsi_open
function during driver's initialization.
In specific situation (ex. 12 cpus online) there were 16 queues
in /sys/class/net/<iface>/queues. In case of modifying queues with
value higher, than number of online cpus, then it caused write
errors and other errors.
Add updating of sysfs's queues representation during driver
initialization.

Subject: [PATCH 5.15 26/72] sctp: hold endpoint before calling cb in sctp_transport_lookup_process

From: Xin Long <[email protected]>

commit f9d31c4cf4c11ff10317f038b9c6f7c3bda6cdd4 upstream.

The same fix in commit 5ec7d18d1813 ("sctp: use call_rcu to free endpoint")
is also needed for dumping one asoc and sock after the lookup.

Fixes: 86fdb3448cc1 ("sctp: ensure ep is not destroyed before doing the dump")

Subject: [PATCH 5.15 52/72] ipv6: Do cleanup if attribute validation fails in multipath route

From: David Ahern <[email protected]>

[ Upstream commit 95bdba23b5b4aa75fe3e6c84335e638641c707bb ]

As Nicolas noted, if gateway validation fails walking the multipath
attribute the code should jump to the cleanup to free previously
allocated memory.

From: Steven Lee <[email protected]>

commit e5a7431f5a2d6dcff7d516ee9d178a3254b17b87 upstream.

Each aspeed sgpio bank has 64 gpio pins(32 input pins and 32 output pins).
The hwirq base for each sgpio bank should be multiples of 64 rather than
multiples of 32.

From: Jianguo Wu <[email protected]>

commit 5e75d0b215b868337e7a193f28a543ec00e858b1 upstream.

As Paolo pointed out, the result of ping IPv6 address depends on
the running distro. So explicitly checking the available ping feature,
as e.g. do the bareudp.sh self-tests.

Subject: [PATCH 5.15 14/72] mac80211: mesh: embedd mesh_paths and mpp_paths into ieee80211_if_mesh

From: Pavel Skripkin <[email protected]>

commit 8b5cb7e41d9d77ffca036b0239177de123394a55 upstream.

Syzbot hit NULL deref in rhashtable_free_and_destroy(). The problem was
in mesh_paths and mpp_paths being NULL.

mesh_pathtbl_init() could fail in case of memory allocation failure, but
nobody cared, since ieee80211_mesh_init_sdata() returns void. It led to
leaving 2 pointers as NULL. Syzbot has found null deref on exit path,
but it could happen anywhere else, because code assumes these pointers are
valid.

Since all ieee80211_*_setup_sdata functions are void and do not fail,
let's embedd mesh_paths and mpp_paths into parent struct to avoid
adding error handling on higher levels and follow the pattern of others
setup_sdata functions

Subject: [PATCH 5.15 53/72] auxdisplay: charlcd: checking for pointer reference before dereferencing

From: Luiz Sampaio <[email protected]>

[ Upstream commit 4daa9ff89ef27be43c15995412d6aee393a78200 ]

Check if the pointer lcd->ops->init_display exists before dereferencing it.
If a driver called charlcd_init() without defining the ops, this would
return segmentation fault, as happened to me when implementing a charlcd
driver. Checking the pointer before dereferencing protects from
segmentation fault.

Subject: [PATCH 5.15 19/72] ftrace/samples: Add missing prototypes direct functions

From: Jiri Olsa <[email protected]>

commit 0daf5cb217a9ca8ae91b8f966ddae322699fb71d upstream.

There's another compilation fail (first here [1]) reported by kernel
test robot for W=1 clang build:

>> samples/ftrace/ftrace-direct-multi-modify.c:7:6: warning: no previous
prototype for function 'my_direct_func1' [-Wmissing-prototypes]
void my_direct_func1(unsigned long ip)

Direct functions in ftrace direct sample modules need to have prototypes
defined. They are already global in order to be visible for the inline
assembly, so there's no problem.

The kernel test robot reported just error for ftrace-direct-multi-modify,
but I got same errors also for the rest of the modules touched by this patch.

Subject: [PATCH 5.15 07/72] i40e: Fix to not show opcode msg on unsuccessful VF MAC change

From: Mateusz Palczewski <[email protected]>

commit 01cbf50877e602e2376af89e4a51c30bc574c618 upstream.

Hide i40e opcode information sent during response to VF in case when
untrusted VF tried to change MAC on the VF interface.

This is implemented by adding an additional parameter 'hide' to the
response sent to VF function that hides the display of error
information, but forwards the error code to VF.

Previously it was not possible to send response with some error code
to VF without displaying opcode information.

Subject: [PATCH 5.15 27/72] batman-adv: mcast: dont send link-local multicast to mcast routers

From: Linus Lüssing <[email protected]>

commit 938f2e0b57ffe8a6df71e1e177b2978b1b33fe5e upstream.

The addition of routable multicast TX handling introduced a
bug/regression for packets with a link-local multicast destination:
These packets would be sent to all batman-adv nodes with a multicast
router and to all batman-adv nodes with an old version without multicast
router detection.

This even disregards the batman-adv multicast fanout setting, which can
potentially lead to an unwanted, high number of unicast transmissions or
even congestion.

Fixing this by avoiding to send link-local multicast packets to nodes in
the multicast router list.

A wrong request id received from the device is a sign that
something is wrong with it, therefore trigger a device reset.

Also add some debug info to the "Page is NULL" print to make
it easier to debug.

Subject: [PATCH 5.15 35/72] cgroup: Use open-time credentials for process migraton perm checks

From: Tejun Heo <[email protected]>

commit 1756d7994ad85c2479af6ae5a9750b92324685af upstream.

cgroup process migration permission checks are performed at write time as
whether a given operation is allowed or not is dependent on the content of
the write - the PID. This currently uses current's credentials which is a
potential security weakness as it may allow scenarios where a less
privileged process tricks a more privileged one into writing into a fd that
it created.

This patch makes both cgroup2 and cgroup1 process migration interfaces to
use the credentials saved at the time of open (file->f_cred) instead of
current's.

This happened because we would overrun the i2c->msgs array on the final
interrupt for the I2C STOP. This didn't happen if the last message was a
read because there is no interrupt in that case. Ensure that we only
access the current message if we are not processing a I2C STOP
condition.

commit 983d8e60f50806f90534cc5373d0ce867e5aaf79 upstream.

The old ALLOCSP/FREESP ioctls in XFS can be used to preallocate space at
the end of files, just like fallocate and RESVSP. Make the behavior
consistent with the other ioctls.

Subject: [PATCH 5.15 70/72] Input: zinitix - make sure the IRQ is allocated before it gets enabled

From: Nikita Travkin <[email protected]>

[ Upstream commit cf73ed894ee939d6706d65e0cd186e4a64e3af6d ]

Since irq request is the last thing in the driver probe, it happens
later than the input device registration. This means that there is a
small time window where if the open method is called the driver will
attempt to enable not yet available irq.

Fix that by moving the irq request before the input device registration.

Currently, userfaultfd selftest for hugetlb as run from run_vmtests.sh
or any environment where there are 'just enough' hugetlb pages will
always fail with:

testing events (fork, remap, remove):
ERROR: UFFDIO_COPY error: -12 (errno=12, line=616)

The ENOMEM error code implies there are not enough hugetlb pages.
However, there are free hugetlb pages but they are all reserved. There
is a basic problem with the way the test allocates hugetlb pages which
has existed since the test was originally written.

Due to the way 'cleanup' was done between different phases of the test,
this issue was masked until recently. The issue was uncovered by commit
8ba6e8640844 ("userfaultfd/selftests: reinitialize test context in each
test").

For the hugetlb test, src and dst areas are allocated as PRIVATE
mappings of a hugetlb file. This means that at mmap time, pages are
reserved for the src and dst areas. At the start of event testing (and
other tests) the src area is populated which results in allocation of
huge pages to fill the area and consumption of reserves associated with
the area. Then, a child is forked to fault in the dst area. Note that
the dst area was allocated in the parent and hence the parent owns the
reserves associated with the mapping. The child has normal access to
the dst area, but can not use the reserves created/owned by the parent.
Thus, if there are no other huge pages available allocation of a page
for the dst by the child will fail.

Fix by not creating reserves for the dst area. In this way the child
can use free (non-reserved) pages.

Also, MAP_PRIVATE of a file only makes sense if you are interested in
the contents of the file before making a COW copy. The test does not do
this. So, just use MAP_ANONYMOUS | MAP_HUGETLB to create an anonymous
hugetlb mapping. There is no need to create a hugetlb file in the
non-shared case.

From: Phil Elwell <[email protected]>

[ Upstream commit c8013355ead68dce152cf426686f8a5f80d88b40 ]

Since [1], added in 5.7, the absence of a gpio-ranges property has
prevented GPIOs from being restored to inputs when released.
Add those properties for BCM283x and BCM2711 devices.

Subject: [PATCH 5.15 42/72] power: reset: ltc2952: Fix use of floating point literals

From: Nathan Chancellor <[email protected]>

commit 644106cdb89844be2496b21175b7c0c2e0fab381 upstream.

A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).

drivers/power/reset/ltc2952-poweroff.c:162:28: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
data->wde_interval = 300L * 1E6L;
^
drivers/power/reset/ltc2952-poweroff.c:162:21: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
data->wde_interval = 300L * 1E6L;
^
drivers/power/reset/ltc2952-poweroff.c:163:41: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
data->trigger_delay = ktime_set(2, 500L*1E6L);
^
3 errors generated.

This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.

There is no visible reason for floating point values in this driver, as
the values are only assigned to integer types. Use NSEC_PER_MSEC, which
is the same integer value as '1E6L', to avoid changing functionality but
fix the error.
