[PATCH 5.10 01/54] nilfs2: fix NULL pointer dereference at nilfs_bmap_lookup_at_level()

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit 21a87d88c2253350e115029f14fe2a10a7e6c856 upstream.

If the i_mode field in inode of metadata files is corrupted on disk, it
can cause the initialization of bmap structure, which should have been
called from nilfs_read_inode_common(), not to be called.  This causes a
lockdep warning followed by a NULL pointer dereference at
nilfs_bmap_lookup_at_level().

This patch fixes these issues by adding a missing sanitiy check for the
i_mode field of metadata file's inode.

[PATCH 5.10 02/54] nilfs2: fix use-after-free bug of struct nilfs_root

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit d325dc6eb763c10f591c239550b8c7e5466a5d09 upstream.

If the beginning of the inode bitmap area is corrupted on disk, an inode
with the same inode number as the root inode can be allocated and fail
soon after.  In this case, the subsequent call to nilfs_clear_inode() on
that bogus root inode will wrongly decrement the reference counter of
struct nilfs_root, and this will erroneously free struct nilfs_root,
causing kernel oopses.

This fixes the problem by changing nilfs_new_inode() to skip reserved
inode numbers while repairing the inode bitmap.

[PATCH 5.10 03/54] nilfs2: fix leak of nilfs_root in case of writer thread creation failure

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit d0d51a97063db4704a5ef6bc978dddab1636a306 upstream.

If nilfs_attach_log_writer() failed to create a log writer thread, it
frees a data structure of the log writer without any cleanup.  After
commit e912a5b66837 ("nilfs2: use root object to get ifile"), this causes
a leak of struct nilfs_root, which started to leak an ifile metadata inode
and a kobject on that struct.

In addition, if the kernel is booted with panic_on_warn, the above
ifile metadata inode leak will cause the following panic when the
nilfs2 kernel module is removed:

[PATCH 5.10 04/54] nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure

[Greg Kroah-Hartman]

From: Ryusuke Konishi <konishi.ryusuke@gmail.com>

commit 723ac751208f6d6540191689cfbf6c77135a7a1b upstream.

If creation or finalization of a checkpoint fails due to anomalies in the
checkpoint metadata on disk, a kernel warning is generated.

This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted
with panic_on_warn, does not panic.  A nilfs_error is appropriate here to
handle the abnormal filesystem condition.

This also replaces the detected error codes with an I/O error so that
neither of the internal error codes is returned to callers.

[PATCH 5.10 05/54] ceph: dont truncate file in atomic_open

[Greg Kroah-Hartman]

From: Hu Weiwen <sehuww@mail.scut.edu.cn>

commit 7cb9994754f8a36ae9e5ec4597c5c4c2d6c03832 upstream.

Clear O_TRUNC from the flags sent in the MDS create request.

`atomic_open' is called before permission check. We should not do any
modification to the file here. The caller will do the truncation
afterward.

[PATCH 5.10 06/54] Makefile.extrawarn: Move -Wcast-function-type-strict to W=1

[Greg Kroah-Hartman]

From: Sami Tolvanen <samitolvanen@google.com>

commit 2120635108b35ecad9c59c8b44f6cbdf4f98214e upstream.

We enable -Wcast-function-type globally in the kernel to warn about
mismatching types in function pointer casts. Compilers currently
warn only about ABI incompability with this flag, but Clang 16 will
enable a stricter version of the check by default that checks for an
exact type match. This will be very noisy in the kernel, so disable
-Wcast-function-type-strict without W=1 until the new warnings have
been addressed.

[PATCH 5.10 10/54] ALSA: pcm: oss: Fix race at SNDCTL_DSP_SYNC

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 8423f0b6d513b259fdab9c9bf4aaa6188d054c2d upstream.

There is a small race window at snd_pcm_oss_sync() that is called from
OSS PCM SNDCTL_DSP_SYNC ioctl; namely the function calls
snd_pcm_oss_make_ready() at first, then takes the params_lock mutex
for the rest.  When the stream is set up again by another thread
between them, it leads to inconsistency, and may result in unexpected
results such as NULL dereference of OSS buffer as a fuzzer spotted
recently.

The fix is simply to cover snd_pcm_oss_make_ready() call into the same
params_lock mutex with snd_pcm_oss_make_ready_locked() variant.

[PATCH 5.10 11/54] mm: gup: fix the fast GUP race against THP collapse

[Greg Kroah-Hartman]

From: Yang Shi <shy828301@gmail.com>

commit 70cbc3cc78a997d8247b50389d37c4e1736019da upstream.

Since general RCU GUP fast was introduced in commit 2667f50e8b81 ("mm:
introduce a general RCU get_user_pages_fast()"), a TLB flush is no longer
sufficient to handle concurrent GUP-fast in all cases, it only handles
traditional IPI-based GUP-fast correctly.  On architectures that send an
IPI broadcast on TLB flush, it works as expected.  But on the
architectures that do not use IPI to broadcast TLB flush, it may have the
below race:

   CPU A                                          CPU B
THP collapse                                     fast GUP
                                              gup_pmd_range() <-- see valid pmd
                                                  gup_pte_range() <-- work on pte
pmdp_collapse_flush() <-- clear pmd and flush
__collapse_huge_page_isolate()
    check page pinned <-- before GUP bump refcount
                                                      pin the page
                                                      check PTE <-- no change
__collapse_huge_page_copy()
    copy data to huge page
    ptep_clear()
install huge pmd for the huge page
                                                      return the stale page
discard the stale page

The race can be fixed by checking whether PMD is changed or not after
taking the page pin in fast GUP, just like what it does for PTE.  If the
PMD is changed it means there may be parallel THP collapse, so GUP should
back off.

Also update the stale comment about serializing against fast GUP in
khugepaged.

[PATCH 5.10 12/54] powerpc/64s/radix: dont need to broadcast IPI for radix pmd collapse flush

[Greg Kroah-Hartman]

From: Yang Shi <shy828301@gmail.com>

commit bedf03416913d88c796288f9dca109a53608c745 upstream.

The IPI broadcast is used to serialize against fast-GUP, but fast-GUP will
move to use RCU instead of disabling local interrupts in fast-GUP.  Using
an IPI is the old-styled way of serializing against fast-GUP although it
still works as expected now.

And fast-GUP now fixed the potential race with THP collapse by checking
whether PMD is changed or not.  So IPI broadcast in radix pmd collapse
flush is not necessary anymore.  But it is still needed for hash TLB.

[PATCH 5.10 13/54] fs: fix UAF/GPF bug in nilfs_mdt_destroy

[Greg Kroah-Hartman]

From: Dongliang Mu <mudongliangabcd@gmail.com>

commit 2e488f13755ffbb60f307e991b27024716a33b29 upstream.

In alloc_inode, inode_init_always() could return -ENOMEM if
security_inode_alloc() fails, which causes inode->i_private
uninitialized. Then nilfs_is_metadata_file_inode() returns
true and nilfs_free_inode() wrongly calls nilfs_mdt_destroy(),
which frees the uninitialized inode->i_private
and leads to crashes(e.g., UAF/GPF).

Fix this by moving security_inode_alloc just prior to
this_cpu_inc(nr_inodes)

[PATCH 5.10 14/54] compiler_attributes.h: move __compiletime_{error|warning}

[Greg Kroah-Hartman]

From: Nick Desaulniers <ndesaulniers@google.com>

commit b83a908498d68fafca931e1276e145b339cac5fb upstream.

Clang 14 will add support for __attribute__((__error__(""))) and
__attribute__((__warning__(""))). To make use of these in
__compiletime_error and __compiletime_warning (as used by BUILD_BUG and
friends) for newer clang and detect/fallback for older versions of
clang, move these to compiler_attributes.h and guard them with
__has_attribute preprocessor guards.

[PATCH 5.10 15/54] firmware: arm_scmi: Add SCMI PM driver remove routine

[Greg Kroah-Hartman]

From: Cristian Marussi <cristian.marussi@arm.com>

[ Upstream commit dea796fcab0a219830831c070b8dc367d7e0f708 ]

Currently, when removing the SCMI PM driver not all the resources
registered with genpd subsystem are properly de-registered.

As a side effect of this after a driver unload/load cycle you get a
splat with a few warnings like this:

 | debugfs: Directory 'BIG_CPU0' with parent 'pm_genpd' already present!
 | debugfs: Directory 'BIG_CPU1' with parent 'pm_genpd' already present!
 | debugfs: Directory 'LITTLE_CPU0' with parent 'pm_genpd' already present!
 | debugfs: Directory 'LITTLE_CPU1' with parent 'pm_genpd' already present!
 | debugfs: Directory 'LITTLE_CPU2' with parent 'pm_genpd' already present!
 | debugfs: Directory 'LITTLE_CPU3' with parent 'pm_genpd' already present!
 | debugfs: Directory 'BIG_SSTOP' with parent 'pm_genpd' already present!
 | debugfs: Directory 'LITTLE_SSTOP' with parent 'pm_genpd' already present!
 | debugfs: Directory 'DBGSYS' with parent 'pm_genpd' already present!
 | debugfs: Directory 'GPUTOP' with parent 'pm_genpd' already present!

Add a proper scmi_pm_domain_remove callback to the driver in order to
take care of all the needed cleanups not handled by devres framework.

[PATCH 5.10 19/54] ARM: dts: fix Moxa SDIO compatible, remove sdhci misnomer

From: Sergei Antonov <saproj@gmail.com>

[ Upstream commit 02181e68275d28cab3c3f755852770367f1bc229 ]

Driver moxart-mmc.c has .compatible = "moxa,moxart-mmc".

But moxart .dts/.dtsi and the documentation file moxa,moxart-dma.txt
contain compatible = "moxa,moxart-sdhci".

Change moxart .dts/.dtsi files and moxa,moxart-dma.txt to match the driver.

Replace 'sdhci' with 'mmc' in names too, since SDHCI is a different
controller from FTSDC010.

[PATCH 5.10 20/54] scsi: qedf: Fix a UAF bug in __qedf_probe()

[Greg Kroah-Hartman]

From: Letu Ren <fantasquex@gmail.com>

[ Upstream commit fbfe96869b782364caebae0445763969ddb6ea67 ]

In __qedf_probe(), if qedf->cdev is NULL which means
qed_ops->common->probe() failed, then the program will goto label err1, and
scsi_host_put() will free lport->host pointer. Because the memory qedf
points to is allocated by libfc_host_alloc(), it will be freed by
scsi_host_put(). However, the if statement below label err0 only checks
whether qedf is NULL but doesn't check whether the memory has been freed.
So a UAF bug can occur.

There are two ways to reach the statements below err0. The first one is
described as before, "qedf" should be set to NULL. The second one is goto
"err0" directly. In the latter scenario qedf hasn't been changed and it has
the initial value NULL. As a result the if statement is not reachable in
any situation.

The KASAN logs are as follows:

[PATCH 5.10 21/54] net/ieee802154: fix uninit value bug in dgram_sendmsg

[Greg Kroah-Hartman]

From: Haimin Zhang <tcs.kernel@gmail.com>

[ Upstream commit 94160108a70c8af17fa1484a37e05181c0e094af ]

There is uninit value bug in dgram_sendmsg function in
net/ieee802154/socket.c when the length of valid data pointed by the
msg->msg_name isn't verified.

We introducing a helper function ieee802154_sockaddr_check_size to
check namelen. First we check there is addr_type in ieee802154_addr_sa.
Then, we check namelen according to addr_type.

Also fixed in raw_bind, dgram_bind, dgram_connect.

[PATCH 5.10 22/54] ALSA: hda/hdmi: Fix the converter reuse for the silent stream

[Greg Kroah-Hartman]

From: Jaroslav Kysela <perex@perex.cz>

[ Upstream commit 5f80d6bd2b01de4cafac3302f58456bf860322fc ]

When the user space pcm stream uses the silent stream converter,
it is no longer allocated for the silent stream. Clear the appropriate
flag in the hdmi_pcm_open() function. The silent stream setup may
be applied in hdmi_pcm_close() (and the error path - open fcn) again.

If the flag is not cleared, the reuse conditions for the silent
stream converter in hdmi_choose_cvt() may improperly share
this converter.

[PATCH 5.10 25/54] arch: um: Mark the stack non-executable to fix a binutils warning

[Greg Kroah-Hartman]

From: David Gow <davidgow@google.com>

[ Upstream commit bd71558d585ac61cfd799db7f25e78dca404dd7a ]

Since binutils 2.39, ld will print a warning if any stack section is
executable, which is the default for stack sections on files without a
.note.GNU-stack section.

This was fixed for x86 in commit ffcf9c5700e4 ("x86: link vdso and boot with -z noexecstack --no-warn-rwx-segments"),
but remained broken for UML, resulting in several warnings:

/usr/bin/ld: warning: arch/x86/um/vdso/vdso.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms1 has a LOAD segment with RWX permissions
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms1.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms2 has a LOAD segment with RWX permissions
/usr/bin/ld: warning: .tmp_vmlinux.kallsyms2.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
/usr/bin/ld: warning: vmlinux has a LOAD segment with RWX permissions

Link both the VDSO and vmlinux with -z noexecstack, fixing the warnings
about .note.GNU-stack sections. In addition, pass --no-warn-rwx-segments
to dodge the remaining warnings about LOAD segments with RWX permissions
in the kallsyms objects. (Note that this flag is apparently not
available on lld, so hide it behind a test for BFD, which is what the
x86 patch does.)

[PATCH 5.10 26/54] net: atlantic: fix potential memory leak in aq_ndev_close()

[Greg Kroah-Hartman]

From: Jianglei Nie <niejianglei2021@163.com>

[ Upstream commit 65e5d27df61283e5390f04b09dc79cd832f95607 ]

If aq_nic_stop() fails, aq_ndev_close() returns err without calling
aq_nic_deinit() to release the relevant memory and resource, which
will lead to a memory leak.

We can fix it by deleting the if condition judgment and goto statement to
call aq_nic_deinit() directly after aq_nic_stop() to fix the memory leak.

[ Upstream commit 52bb21499cf54fa65b56d97cd0d68579c90207dd ]

[Why]
The desktop plane and full-screen game plane may have different
gamut remap coefficients, if switching between desktop and
full-screen game without updating the gamut remap will cause
incorrect color.

[How]
Update gamut remap if planes change.

From: zhikzhai <zhikai.zhai@amd.com>

[ Upstream commit 65fbfb02c2734cacffec5e3f492e1b4f1dabcf98 ]

[why]
We have minimal pipe split transition method to avoid pipe
allocation outage.However, this method will invoke audio setup
which cause audio output stuck once pipe reallocate.

[how]
skip audio setup for pipelines which audio stream has been enabled

[PATCH 5.10 30/54] mmc: core: Terminate infinite loop in SD-UHS voltage switch

[Greg Kroah-Hartman]

From: Brian Norris <briannorris@chromium.org>

[ Upstream commit e9233917a7e53980664efbc565888163c0a33c3f ]

This loop intends to retry a max of 10 times, with some implicit
termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the
termination condition depends on the value reported by the SD card
(*rocr), which may or may not correctly reflect what we asked it to do.

Needless to say, it's not wise to rely on the card doing what we expect;
we should at least terminate the loop regardless. So, check both the
input and output values, so we ensure we will terminate regardless of
the SD card behavior.

Note that SDIO learned a similar retry loop in commit 0797e5f1453b
("mmc: core: Fixup signal voltage switch"), but that used the 'ocr'
result, and so the current pre-terminating condition looks like:

    rocr & ocr & R4_18V_PRESENT

(i.e., it doesn't have the same bug.)

This addresses a number of crash reports seen on ChromeOS that look
like the following:

    ... // lots of repeated: ...

[PATCH 5.10 31/54] usb: mon: make mmapped memory read only

[Greg Kroah-Hartman]

From: Tadeusz Struk <tadeusz.struk@linaro.org>

commit a659daf63d16aa883be42f3f34ff84235c302198 upstream.

Syzbot found an issue in usbmon module, where the user space client can
corrupt the monitor's internal memory, causing the usbmon module to
crash the kernel with segfault, UAF, etc.

The reproducer mmaps the /dev/usbmon memory to user space, and
overwrites it with arbitrary data, which causes all kinds of issues.

Return an -EPERM error from mon_bin_mmap() if the flag VM_WRTIE is set.
Also clear VM_MAYWRITE to make it impossible to change it to writable
later.

[PATCH 5.10 33/54] rpmsg: qcom: glink: replace strncpy() with strscpy_pad()

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

commit 766279a8f85df32345dbda03b102ca1ee3d5ddea upstream.

The use of strncpy() is considered deprecated for NUL-terminated
strings[1]. Replace strncpy() with strscpy_pad(), to keep existing
pad-behavior of strncpy, similarly to commit 08de420a8014 ("rpmsg:
glink: Replace strncpy() with strscpy_pad()").  This fixes W=1 warning:

[PATCH 5.10 35/54] random: restore O_NONBLOCK support

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit cd4f24ae9404fd31fc461066e57889be3b68641b upstream.

Prior to 5.6, when /dev/random was opened with O_NONBLOCK, it would
return -EAGAIN if there was no entropy. When the pools were unified in
5.6, this was lost. The post 5.6 behavior of blocking until the pool is
initialized, and ignoring O_NONBLOCK in the process, went unnoticed,
with no reports about the regression received for two and a half years.
However, eventually this indeed did break somebody's userspace.

So we restore the old behavior, by returning -EAGAIN if the pool is not
initialized. Unlike the old /dev/random, this can only occur during
early boot, after which it never blocks again.

In order to make this O_NONBLOCK behavior consistent with other
expectations, also respect users reading with preadv2(RWF_NOWAIT) and
similar.

Fixes: 30c08efec888 ("random: make /dev/random be almost like /dev/urandom")

[PATCH 5.10 36/54] random: clamp credited irq bits to maximum mixed

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit e78a802a7b4febf53f2a92842f494b01062d85a8 upstream.

Since the most that's mixed into the pool is sizeof(long)*2, don't
credit more than that many bytes of entropy.

[PATCH 5.10 37/54] ALSA: hda: Fix position reporting on Poulsbo

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 56e696c0f0c71b77fff921fc94b58a02f0445b2c upstream.

Hans reported that his Sony VAIO VPX11S1E showed the broken sound
behavior at the start of the stream for a couple of seconds, and it
turned out that the position_fix=1 option fixes the issue.  It implies
that the position reporting is inaccurate, and very likely hitting on
all Poulsbo devices.

The patch applies the workaround for Poulsbo generically to switch to
LPIB mode instead of the default position buffer.

[PATCH 5.10 38/54] efi: Correct Macmini DMI match in uefi cert quirk

[Greg Kroah-Hartman]

From: Orlando Chamberlain <redecorating@protonmail.com>

commit bab715bdaa9ebf28d99a6d1efb2704a30125e96d upstream.

It turns out Apple doesn't capitalise the "mini" in "Macmini" in DMI, which
is inconsistent with other model line names.

Correct the capitalisation of Macmini in the quirk for skipping loading
platform certs on T2 Macs.

Currently users get:

[PATCH 5.10 39/54] scsi: stex: Properly zero out the passthrough command structure

[Greg Kroah-Hartman]

From: Linus Torvalds <torvalds@linux-foundation.org>

commit 6022f210461fef67e6e676fd8544ca02d1bcfa7a upstream.

The passthrough structure is declared off of the stack, so it needs to be
set to zero before copied back to userspace to prevent any unintentional
data leakage.  Switch things to be statically allocated which will fill the
unused fields with 0 automatically.

[PATCH 5.10 41/54] random: avoid reading two cache lines on irq randomness

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit 9ee0507e896b45af6d65408c77815800bce30008 upstream.

In order to avoid reading and dirtying two cache lines on every IRQ,
move the work_struct to the bottom of the fast_pool struct. add_
interrupt_randomness() always touches .pool and .count, which are
currently split, because .mix pushes everything down. Instead, move .mix
to the bottom, so that .pool and .count are always in the first cache
line, since .mix is only accessed when the pool is full.

[PATCH 5.10 42/54] random: use expired timer rather than wq for mixing fast pool

[Greg Kroah-Hartman]

From: Jason A. Donenfeld <Jason@zx2c4.com>

commit 748bc4dd9e663f23448d8ad7e58c011a67ea1eca upstream.

Previously, the fast pool was dumped into the main pool periodically in
the fast pool's hard IRQ handler. This worked fine and there weren't
problems with it, until RT came around. Since RT converts spinlocks into
sleeping locks, problems cropped up. Rather than switching to raw
spinlocks, the RT developers preferred we make the transformation from
originally doing:

    do_some_stuff()
    spin_lock()
    do_some_other_stuff()
    spin_unlock()

to doing:

    do_some_stuff()
    queue_work_on(some_other_stuff_worker)

This is an ordinary pattern done all over the kernel. However, Sherry
noticed a 10% performance regression in qperf TCP over a 40gbps
InfiniBand card. Quoting her message:

> MT27500 Family [ConnectX-3] cards:

> phys state: 5: LinkUp
> rate: 40 Gb/sec (4X QDR)
> link_layer: InfiniBand
>
> Cards are configured with IP addresses on private subnet for IPoIB
> performance testing.
> Regression identified in this bug is in TCP latency in this stack as reported
> by qperf tcp_lat metric:
>
> We have one system listen as a qperf server:
> [root@yourQperfServer ~]# qperf

> Have the other system connect to qperf server as a client (in this

Rather than incur the scheduling latency from queue_work_on, we can
instead switch to running on the next timer tick, on the same core. This
also batches things a bit more -- once per jiffy -- which is okay now
that mix_interrupt_randomness() can credit multiple bits at once.

[PATCH 5.10 43/54] wifi: cfg80211: fix u8 overflow in cfg80211_update_notlisted_nontrans()

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit aebe9f4639b13a1f4e9a6b42cdd2e38c617b442d upstream.

In the copy code of the elements, we do the following calculation
to reach the end of the MBSSID element:

	/* copy the IEs after MBSSID */
	cpy_len = mbssid[1] + 2;

This looks fine, however, cpy_len is a u8, the same as mbssid[1],
so the addition of two can overflow. In this case the subsequent
memcpy() will overflow the allocated buffer, since it copies 256
bytes too much due to the way the allocation and memcpy() sizes
are calculated.

Fix this by using size_t for the cpy_len variable.

This fixes CVE-2022-41674.

[PATCH 5.10 44/54] wifi: cfg80211/mac80211: reject bad MBSSID elements

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream.

Per spec, the maximum value for the MaxBSSID ('n') indicator is 8,
and the minimum is 1 since a multiple BSSID set with just one BSSID
doesn't make sense (the # of BSSIDs is limited by 2^n).

Limit this in the parsing in both cfg80211 and mac80211, rejecting
any elements with an invalid value.

This fixes potentially bad shifts in the processing of these inside
the cfg80211_gen_new_bssid() function later.

I found this during the investigation of CVE-2022-41674 fixed by the
previous patch.

Longer term, we should rewrite this code using the type-safe

[PATCH 5.10 46/54] wifi: cfg80211: fix BSS refcounting bugs

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit 0b7808818cb9df6680f98996b8e9a439fa7bcc2f upstream.

There are multiple refcounting bugs related to multi-BSSID:
 - In bss_ref_get(), if the BSS has a hidden_beacon_bss, then
   the bss pointer is overwritten before checking for the
   transmitted BSS, which is clearly wrong. Fix this by using
   the bss_from_pub() macro.

 - In cfg80211_bss_update() we copy the transmitted_bss pointer
   from tmp into new, but then if we release new, we'll unref
   it erroneously. We already set the pointer and ref it, but
   need to NULL it since it was copied from the tmp data.

 - In cfg80211_inform_single_bss_data(), if adding to the non-
   transmitted list fails, we unlink the BSS and yet still we
   return it, but this results in returning an entry without
   a reference. We shouldn't return it anyway if it was broken
   enough to not get added there.

This fixes CVE-2022-42720.

[PATCH 5.10 47/54] wifi: cfg80211: avoid nontransmitted BSS list corruption

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit bcca852027e5878aec911a347407ecc88d6fff7f upstream.

If a non-transmitted BSS shares enough information (both
SSID and BSSID!) with another non-transmitted BSS of a
different AP, then we can find and update it, and then
try to add it to the non-transmitted BSS list. We do a
search for it on the transmitted BSS, but if it's not
there (but belongs to another transmitted BSS), the list
gets corrupted.

Since this is an erroneous situation, simply fail the
list insertion in this case and free the non-transmitted
BSS.

This fixes CVE-2022-42721.

[PATCH 5.10 48/54] wifi: mac80211_hwsim: avoid mac80211 warning on bad rate

From: Johannes Berg <johannes.berg@intel.com>

commit 1833b6f46d7e2830251a063935ab464256defe22 upstream.

If the tool on the other side (e.g. wmediumd) gets confused
about the rate, we hit a warning in mac80211. Silence that
by effectively duplicating the check here and dropping the
frame silently (in mac80211 it's dropped with the warning).

[PATCH 5.10 49/54] wifi: mac80211: fix crash in beacon protection for P2P-device

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit b2d03cabe2b2e150ff5a381731ea0355459be09f upstream.

If beacon protection is active but the beacon cannot be
decrypted or is otherwise malformed, we call the cfg80211
API to report this to userspace, but that uses a netdev
pointer, which isn't present for P2P-Device. Fix this to
call it only conditionally to ensure cfg80211 won't crash
in the case of P2P-Device.

This fixes CVE-2022-42722.

[PATCH 5.10 50/54] wifi: cfg80211: update hidden BSSes to avoid WARN_ON

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

commit c90b93b5b782891ebfda49d4e5da36632fefd5d1 upstream.

When updating beacon elements in a non-transmitted BSS,
also update the hidden sub-entries to the same beacon
elements, so that a future update through other paths
won't trigger a WARN_ON().

The warning is triggered because the beacon elements in
the hidden BSSes that are children of the BSS should
always be the same as in the parent.

commit a17b9841152e7f4621619902b347e2cc39c32996 upstream.

Suspending and resuming the system can sometimes cause the out
URB to get hung after a reset_resume. This causes LED setting
and force feedback to break on resume. To avoid this, just drop
the reset_resume callback so the USB core rebinds xpad to the
wireless pads on resume if a reset happened.

A nice side effect of this change is the LED ring on wireless
controllers is now set correctly on system resume.

[PATCH 5.10 53/54] misc: pci_endpoint_test: Aggregate params checking for xfer

[Greg Kroah-Hartman]

From: Shunsuke Mie <mie@igel.co.jp>

commit 3e42deaac06567c7e86d287c305ccda24db4ae3d upstream.

Each transfer test functions have same parameter checking code. This patch
unites those to an introduced function.

[PATCH 5.10 54/54] misc: pci_endpoint_test: Fix pci_endpoint_test_{copy,write,read}() panic

[Greg Kroah-Hartman]

From: Shunsuke Mie <mie@igel.co.jp>

commit 8e30538eca016de8e252bef174beadecd64239f0 upstream.

The dma_map_single() doesn't permit zero length mapping. It causes a follow
panic.

A panic was reported on arm64:

Just a note: I am debugging drm issue from a previous rc (5.10.146) and
I will let you know once I bisect and figure the offending patch.

This is not related to this rc - doesn't stop from releasing this one.
