6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
[ Upstream commit 826af7fa62e347464b1b4e0ba2fe19a92438084f ]
The PCM trigger callback of aloop driver tries to check the PCM state
and stop the stream of the tied substream in the corresponding cable.
Since both check and stop operations are performed outside the cable
lock, this may result in UAF when a program attempts to trigger
frequently while opening/closing the tied stream, as spotted by
fuzzers.
For addressing the UAF, this patch changes two things:
- It covers the most of code in loopback_check_format() with
cable->lock spinlock, and add the proper NULL checks. This avoids
already some racy accesses.
- In addition, now we try to check the state of the capture PCM stream
that may be stopped in this function, which was the major pain point
leading to UAF.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cássio Gabriel <cassiogabrielcontato@gmail.com>
[ Upstream commit e5c33cdc6f402eab8abd36ecf436b22c9d3a8aff ]
loopback_check_format() may stop the capture side when playback starts
with parameters that no longer match a running capture stream. Commit
826af7fa62e3 ("ALSA: aloop: Fix racy access at PCM trigger") moved
the peer lookup under cable->lock, but the actual snd_pcm_stop() still
runs after dropping that lock.
A concurrent close can clear the capture entry from cable->streams[] and
detach or free its runtime while the playback trigger path still holds a
stale peer substream pointer.
Keep a per-cable count of in-flight peer stops before dropping
cable->lock, and make free_cable() wait for those stops before
detaching the runtime. This preserves the existing behavior while
making the peer runtime lifetime explicit.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matt Turner <mattst88@gmail.com>
commit 49672d026cc4773608e1222b69b29fd70f41336b upstream.
ieee_swcr_to_fpcr() converts the software IEEE trap-enable and status
bits kept in thread_info.ieee_state into the hardware FPCR format. It
contained:
fp |= (~sw & IEEE_TRAP_ENABLE_DNO) << 41;
FPCR_DNOD (bit 47) disables denormal operand traps: with it set the
hardware handles a denormal operand itself, treating it as zero, instead
of trapping for software completion. The intent was to set DNOD when the
user has not asked for SIGFPE on denormal operands, but
IEEE_TRAP_ENABLE_DNO is clear by default, so ieee_swcr_to_fpcr(0) always
set DNOD.
Instructions built with the software completion suffix therefore never
trapped on a denormal operand. The hardware silently substituted zero
and produced wrong results, affecting every program compiled with -mieee
and default FPU settings, glibc included.
Set FPCR_DNOD only when IEEE_MAP_DMZ is requested, which is exactly the
case where flushing denormal inputs to zero is what the user asked for.
DNOD then encodes MAP_DMZ, which ieee_fpcr_to_swcr() already recovers
from FPCR_DNZ, so drop its attempt to recover IEEE_TRAP_ENABLE_DNO from
DNOD; the DNO trap enable lives solely in ieee_state.
Both functions are in a uapi header, so the encoding change is visible to
userspace, but nothing outside the kernel is known to depend on DNOD
carrying the DNO trap enable, and the kernel is the only writer of the
FPCR.
This must not be backported on its own. Re-enabling denormal operand
traps exposes a second bug, fixed in the following patch: those traps
usually find an exact result, and for an exact result the emulator did
not write the FPCR back, leaving hardware-fabricated exception bits
visible to user space. Taken alone this change would make spurious
exception flags more common.
The bug predates the git history, so there is no commit to reference in a
Fixes tag.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matt Turner <mattst88@gmail.com>
commit bcfe3187412e342b4619efb92c945f073855ebc0 upstream.
On EV6 and later the hardware records exception status bits in the FPCR
before delivering a software completion trap, and those bits can be wrong
for the instruction that trapped. Converting a double that is exactly
representable as a subnormal float sets FPCR_UNF even though the result
is exact, and an underflow trap additionally sets FPCR_INE even when the
emulated operation turns out to be exact.
alpha_fp_emul() only wrote the FPCR when soft-fp raised an exception, so
whenever it determined that the instruction was exact the fabricated bits
stayed in the FPCR and were reported to user space by fetestexcept().
Pass the exception summary register down from do_entArith() so the
handler can tell which exceptions the hardware attributed to the trapping
instruction, and always write the FPCR. Clear the exceptions that the
trap reported but that soft-fp did not raise. EXC_SUM reports only the
underflow or overflow when the hardware also set INE, so treat INE as a
candidate in that case, and treat a trap with no reported exception as a
denormal operand trap, for which the hardware can fabricate INE and UNF
as well. Bits that software has already confirmed in ieee_state belong
to this or an earlier instruction and are never cleared.
The imprecise path passes no summary. There the trap was taken somewhere
in the trap shadow, so EXC_SUM is not attribution for the instruction
being re-executed -- and only EV6, which traps precisely and so never
takes that path, has fabricated bits to clear. For the same reason the
clearing is guarded by implver(), matching swcr_update_status().
On an UP1500 (EV68) this takes the glibc math testsuite from 831 failures
to 28, the remainder being unrelated to exception status.
This belongs with the preceding fix to ieee_swcr_to_fpcr(), and should
not be backported without it -- nor it without this. That fix stops
FPCR_DNOD being set unconditionally, so denormal operand traps start
firing again. Those traps very often find an exact result, which is
precisely the case where the old code left the FPCR unwritten and the
fabricated bits visible. Applied alone it would make spurious exception
flags more common, not less.
One case cannot be resolved here: an inexact instruction without the
software completion suffix never traps, so its INE reaches the FPCR
without being recorded anywhere else. Such a bit is indistinguishable
from an INE the hardware fabricated for a trapping instruction, and is
lost if an underflow or overflow trap with an exact result follows it.
The FPCR is the only record of those instructions and it carries no
attribution.
The bug predates the git history, so there is no commit to reference in a
Fixes tag.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Yan <felixonmars@archlinux.org>
commit d21808328225ab8cee46885bf9a0dffcefbe630e upstream.
sun4i_clkevt_next_event() compensates for the timer stop/start
synchronization delay by programming evt - TIMER_SYNC_TICKS into the
hardware interval register. The clockevent device currently advertises
TIMER_SYNC_TICKS as min_delta_ticks, so the clockevents core is allowed
to call set_next_event() with evt == TIMER_SYNC_TICKS.
That programs a zero-tick interval. With oneshot/highres/nohz timer
operation this can leave the next event stuck, which was observed as a
boot hang on Allwinner D1 after the clockevents core started reusing
forced minimum-delta events.
Advertise one extra tick instead, so the smallest event accepted by the
core still programs at least one hardware tick after the synchronization
compensation.
Fixes: 12e1480bcb49 ("clocksource: sun4i: Report the minimum tick that we can program")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gaurav Batra <gbatra@linux.ibm.com>
commit 1304643a1c20badbb91b86a5084dd76cb7620c05 upstream.
In PowerPC (pseries) a non-virtualized adapter will have 2 DMA windows -
2GB default and a larger Dynamic DMA Window (DDW). DDW is large enough to
map total RAM to a device.
During normal functioning of OS, since RAM is pre-mapped, 2GB default
window is not used. The only scenario it might get used is when buffers in
pmemory are mapped to the device for DMA.
As of today, during kdump, during early device discovery, pci_dma_find()
finds that the device has 2 DMA windows. It selects to use DDW. This is a
kdump path and DMA window is needed for IO to the device.
Although commit 09a3c1e46142 ("powerpc/pseries/iommu: IOMMU table is not
initialized for kdump over SR-IOV") fixed an issue during kdump with SR-IOV
case, but this also made the kdump prefer DDW over the default DMA window
when both are present (dedicated adapter case). Since the DDW is fully
mapped by the previous kernel, iommu_table_clear() can free only
KDUMP_MIN_TCE_ENTRIES (2048) TCEs for use by kdump kernel.
This is not enough when the dump device is NVMe over Fibre Channel.
Because nvme-fc driver DMA-maps the cmds and resp IUs of every
pre-allocated request and each such mapping consumes roughly:
32 (IO queues, one per cpus = nr_cpus) *
64 (queue_depth, blk-mq kdump limit) *
2 (cmd+resp) = 4096
This is already double of what we have without counting admin queues and
lpfc driver's own allocations / mapping requirement. Hence this results
into iommu_alloc failures like -
lpfc 0153:70:00.0: iommu_alloc failed,
tbl 0000000034ebcf5e vaddr 00000000d814df0b npages 1
lpfc 0153:70:00.0: FCP Op failed - cmdiu dma mapping failed.
lpfc 0153:70:00.0: iommu_alloc failed,
tbl 0000000034ebcf5e vaddr 000000009779e4d2 npages 1

nvme_fc_connect_ctrl_work+0x85c/0xdac [nvme_fc]
process_one_work+0x1e4/0x5a0
worker_thread+0x1ec/0x3e0
Increasing the number of free TCE entries in iommu_table_clear() will
increase the probability of hitting EEH since there could still be some
active IOs from the previous life of the kernel.
Hence this patch partially reverts the previous fixes commit and
switches the kdump's default back to 2GB default DMA window instead of
DDW window. This window will mostly be empty. Or, could be slightly used
if buffers in pmemory were mapped for IO.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jérémy Jean <Jeremy.Jean@oss.cyber.gouv.fr>
commit 18c7d85864e554adc8fad1e8d2e9d2cb6c3911c8 upstream.
On native sparc64, struct __kernel_old_timeval contains a four-byte hole
after tv_usec because tv_sec is 64-bit while __kernel_suseconds_t is 32-bit.
put_itimerval() fills only the named fields in a stack-allocated
__kernel_old_itimerval and copies the entire object to userspace, so
getitimer() can expose the two padding holes.
Zero-initialize the aggregate before assigning the fields so implicit
padding is deterministic before it crosses the user/kernel boundary.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jordan R Abrahams-Whitehead <ajordanr@google.com>
commit 2780860eddecba9ffe210bb9436eee3cf22bfcdd upstream.
This commit resolves an issue where modpost section verification fails due
to section mismatches between list_add and its callers.
At present, list_add (and its internal __list_add) are called from both
.text and .init code sections. Since inlining can vary per call site,
list_add can be 4 different states:
list_add in text with arguments to non-.init.data values
list_add in init with arguments to static .init.data values
list_add in init with arguments to non-.init.data values
list_add in text with arguments to static .init.data values
It is last instance that ends up causing the section mismatch caused by
constant propagation of the address of static libs inside the `dir_add` as
seen below (with the dir_list being defined statically in initramfs.c,
resting in .init.data).
WARNING: modpost: vmlinux.o: section mismatch in reference: __list_add
(section: .text.unlikely.) -> dir_list (section: .init.data)
Because of these section matching requirements, semantically, __list_add
and list_add MUST be inlined. This will then ensure callers inside .init
will receive a list_add that exists and refers to only .init data, and
list_add code in .text sections will only refer to non-init data.
This issue manifests predominently in AutoFDO with clang, which is very
hesitant to inline cold functions such as list_add even when marked
`inline`. Marking them as `__always_inline` therefore matches the
existing semantic constraints imposed by modpost's section mismatch
checks.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Breno Leitao <leitao@debian.org>
commit efe8f86c0916f0f74eea74ae21a3b37f728c6bad upstream.
migrate_pages_batch() unmaps each folio before moving it, and every
unmap runs the mmu_notifier invalidate callbacks. On KVM hosts
try_to_migrate() ends up in kvm_mmu_notifier_invalidate_range_start() ->
tdp_mmu_zap_leafs(), which is expensive, so unmapping a large batch keeps
the CPU busy for a long time.
The loop already calls cond_resched(), but on PREEMPTION kernels that is
a no-op, and involuntary preemption is not a Tasks-RCU quiescent state.
A long batch therefore never reports a quiescent state, and the
migrating task (e.g. kcompactd) becomes a Tasks-RCU holdout, stalling the
Tasks-RCU grace period for minutes, which is common at Meta fleet:
INFO: rcu_tasks detected stalls on tasks:
0000000055349ecc: .. nvcsw: 1157401/1157401 holdout: 1 idle_cpu: -1/56 task:kcompactd0 state:R running task

Use cond_resched_tasks_rcu_qs() so a quiescent state is reported even
when cond_resched() does nothing.

Nothing promises direct reclaim returns in bounded time, and the scan loop
in shrink_lruvec() only calls cond_resched(), which is a no-op on
PREEMPTION kernels. Involuntary preemption is not a Tasks-RCU quiescent
state, so the reclaiming task never reports one and becomes a holdout.
Upgrade it to cond_resched_tasks_rcu_qs(), which reports a quiescent state
even when cond_resched() does nothing.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Guopeng Zhang <zhangguopeng@kylinos.cn>
commit 9477820c63cbf4d97114238f3d1ff10dfd6bee3f upstream.
kernfs serializes file operations only per open file, so separate open
files can update the same memory.high or memory.max file concurrently.
Both handlers store the new limit before synchronous reclaim, but continue
to use the writer's local target in the reclaim loop. If another writer
raises or removes the limit, the first writer can continue reclaiming
toward a stale target.
For memory.max, this can leave the writer looping indefinitely once
reclaim retries are exhausted. The OOM path sees sufficient margin under
the current limit and returns true without killing, while the writer still
compares usage against its stale target and records another OOM event.
Check the current limit at the start of each reclaim iteration and stop if
it no longer matches the writer's target.
Reproducer:
Populate a cgroup with anonymous memory and disable swapping. Lower
memory.max from one open file, then restore it to "max" through another
open file after the new limit becomes visible.
Without the patch, the first writer remains blocked and repeatedly
increments the OOM event counter. With the patch, it returns normally.
This was not motivated by a reported production workload. We found it
through automated randomized testing for our cgroup observability work
and reduced it to the reproducer above.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joy H.J. Lee <rkr0k0r@gmail.com>
commit 8700a4761beb219873956666cf91776a2c61e698 upstream.
glibc 2.42 added __attribute_const__ to sys/cdefs.h:
# define __attribute_const__ __attribute__ ((__const__))
GCC 15 warns when a macro is redefined to a different replacement list
(-Wbuiltin-macro-redefined). Since host tool Makefiles (resolve_btfids,
objtool) pass -Werror, this conflict becomes fatal.
The warning is suppressed on standard native builds because GCC treats
/usr/include as a system header path (-isystem), and macro-redefinition
warnings from system headers are silently suppressed by GCC. It fires
when glibc headers are on a regular include path (-I) instead, which
is the case in cross-compilation setups such as NixOS, where the
sysroot's glibc is passed explicitly via -I rather than -isystem.
Per (C11 6.10.3), identical replacement lists are accepted silently.
Match the glibc definition exactly, including the space before "((", so
the redefinition is accepted without warning regardless of whether
glibc headers are treated as system or non-system includes.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kiryl Shutsemau (Meta) <kas@kernel.org>
commit 0f63e656b1c679d32ac595de29d10c03efca6a25 upstream.
handle_in() and handle_out() in arch/x86/coco/tdx/tdx.c use:
u64 mask = GENMASK(BITS_PER_BYTE * size, 0);
GENMASK(h, l) includes bit h. For size=1 (INB), this produces
GENMASK(8, 0) = 0x1FF (9 bits) instead of GENMASK(7, 0) = 0xFF (8
bits). The mask is one bit too wide for all I/O sizes.
Fix the mask calculation.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kiryl Shutsemau (Meta) <kas@kernel.org>
commit 1fe104b048d77d6cb25bd938e6a67450fb50e61d upstream.
KVM's instruction emulator has a small helper, assign_register(), that
writes a value into a register following the x86 rules for writes to
general-purpose registers: an 8- or 16-bit write leaves the rest of the
register untouched, a 32-bit write zero-extends the result to 64 bits,
and a 64-bit write replaces the whole register.
The TDX guest #VE handler needs the same logic for port I/O emulation
to get 32-bit zero-extension right. Rather than add a third copy of
the same switch, move the helper verbatim to <asm/insn-eval.h>, rename
it to insn_assign_reg(), and route KVM's callers through it.
Add <asm/insn.h> to the header's includes so it builds standalone in
callers that have not pulled it in transitively.
No functional change.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sanman Pradhan <psanman@juniper.net>
commit 75d42d990335322852ed5f7ce324b701c0949d79 upstream.
hisi_ptt_wait_dma_reset_done() discards the return value of
readl_poll_timeout_atomic(). If the DMA engine does not complete its
reset within the timeout, hisi_ptt_trace_start() proceeds to start
tracing regardless.
Return a bool from hisi_ptt_wait_dma_reset_done(), consistent with the
other wait helpers in this driver. On timeout, log an error, de-assert
the reset bit, and return -ETIMEDOUT. Move ctrl->started to the
successful path so a failed start does not leave the trace marked as
active.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hui Su <sh_def@163.com>
commit 649bc7df3e5d7be6f7996a95084037dbf3cad1e5 upstream.
event_test_stuff() calls kthread_run() and unconditionally passes the
returned task_struct pointer to kthread_stop(). kthread_run() returns an
error pointer such as ERR_PTR(-ENOMEM) when kthread creation fails, for
example under memory pressure during the boot-time event self-test.
kthread_stop() then dereferences the invalid pointer, crashing the kernel.
Check the result of kthread_run() before passing it to kthread_stop(). Use
WARN_ON() so that a failure to create the self-test thread does not go
unnoticed, matching the ring-buffer self-test fix in commit
91542863abad ("ring-buffer: Fix crash passing ERR_PTR to kthread_stop()").

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hui Su <sh_def@163.com>
commit a7318172aa332a161fb9618286e64454c827f8fd upstream.
When two hist triggers on different events are registered with the same
name=, the second one reuses the first as named_data. Both are added to
tr->hist_vars by save_hist_vars() during event_hist_trigger_parse(),
because save_hist_vars() is called before event_trigger_register() while
the named reuse is only detected later, in hist_register_trigger().
In the named-data branch hist_register_trigger() then frees the second
histogram's hist_data via destroy_hist_data(), but never removes its
tr->hist_vars list entry, leaving a dangling pointer and leaking the
trace_array reference it holds.
A later hist trigger that references a variable makes find_var_file()
walk tr->hist_vars and dereference the freed hist_data. The bug is
reproducible from userspace by writing three hist triggers to tracefs:
cd /sys/kernel/tracing
echo 'hist:keys=common_pid:x=common_pid:name=mh' > events/sched/sched_switch/trigger
echo 'hist:keys=common_pid:x=common_pid:name=mh' > events/sched/sched_process_fork/trigger
echo 'hist:keys=common_pid:vals=$x' > events/sched/sched_process_exit/trigger
The third write panics the kernel:

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xu Yang <xu.yang_2@nxp.com>
commit 1900692555826753adab8799a1a8d50bb1ee200c upstream.
When iterate over children of a fwnode that has a secondary fwnode,
fwnode_get_next_child_node() can enter an infinite loop if the secondary
fwnode has more than one child.
Parent Child
(Primary fwnode) FWa: {FWa1, FWa2, FWa3}
(Secondary fwnode) FWb: {FWb1, FWb2}
In this case:
┌─> fwnode_get_next_child_node(FWa, FWa1)
│ - fwnode_call_ptr_op(FWa, get_next_child_node, FWa1) returns FWa2
│
│ ...
│
│ fwnode_get_next_child_node(FWa, FWa3)
│ - fwnode_call_ptr_op(FWa, get_next_child_node, FWa3) returns NULL
│ - fwnode_call_ptr_op(FWb, get_next_child_node, FWa3) returns FWb1
│
│ fwnode_get_next_child_node(FWa, FWb1)
│ - fwnode_call_ptr_op(FWa, get_next_child_node, FWb1) returns FWa1
└────┘
This cause fwnode_for_each_child_node() to loop indefinitely, reapeatedly
output {FWa1, FWa2, FWa3, FWb1, FWa1, ...}.
The root cause is that when the current child (FWb1) belongs to the
secondary fwnode, calling get_next_child_node() on the parimary fwnode
incorrectly returns the first child (FWa1) again instead of NULL.
Fix this by dynamically checking the parent fwnode of the current child
before calling get_next_child_node(). This approach follows the pattern
established in commit b5b41ab6b0c1 ("device property: Check
fwnode->secondary in fwnode_graph_get_next_endpoint()").
Fixes: 2692c614f8f0 ("device property: Allow secondary lookup in fwnode_get_next_child_node()")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>
commit bd0abfe6b013aeb2a1aebc5fbc7ceeb50355bda3 upstream.
Platform devices created with platform_device_alloc() call
platform_device_release() when the last reference to the device's
kobject is dropped. This function calls of_node_put() unconditionally.
This works fine for devices created with platform_device_register_full()
but users of the split approach (platform_device_alloc() +
platform_device_add()) must bump the reference of the of_node they
assign manually. Add the missing call to of_node_get().

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: James Kim <james010kim@gmail.com>
commit 5cbef379a94b161726c5f504598bf4791d45cedc upstream.
dma_req_free() acquires buf_mutex through req->map, drops the mapping
reference with kref_put(), and then dereferences req->map again to unlock
the mutex.
If kref_put() drops the last reference, mport_release_mapping() frees the
mapping, and the subsequent mutex_unlock() dereferences a freed object.
This is a use-after-free.
Fix this by caching map and md before kref_put(), clearing req->map while
holding buf_mutex, and using the cached md for mutex unlocking.
The bug is reachable from userspace via the RapidIO mport character device
interface.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans Verkuil <hverkuil+cisco@kernel.org>
commit e7600f5cee5de14065f950807931d6e6d40fb2d7 upstream.
This reverts commit 2a934fdb01db6458288fc9386d3d8ceba6dd551a.
The intentions of that patch were good, but it doesn't work.
The idea is that if device_register fails, you have to do a put_device
to let the ref counter release resources.
However, the V4L2 API says that if video_register_device() fails, then
you have to call video_device_release(), which kfree()s the video_device
struct.
But the put_device() will already have freed the struct, so you end
up in a double-free scenario.
There is not really a good way of fixing this without breaking
video_register_device() into two parts, one that initializes everything,
and one that does the actual device_register, and then converting all
V4L2 drivers to this new model.
That is a massive job, and it is very unlikely that device_register
will fail.
So rather than ending up in a double-free scenario, just revert this
patch, and in that case we'll have a small memory leak. Which is a lot
more robust.

From: Hao-Qun Huang <alvinhuang0603@gmail.com>
commit 6d45195a9626d8aaaaed212c55638829a9c624a3 upstream.
__gb_hid_output_raw_report() stores the result of gb_hid_set_report()
in ret and even adjusts it to account for the report ID byte, but then
always returns 0.
This hides Greybus transport errors from HID_REQ_SET_REPORT callers,
and makes hidraw report zero bytes written to user space on success,
although hid_hw_raw_request() is expected to return the number of
bytes transferred or a negative errno. The sibling GET_REPORT path,
__gb_hid_get_raw_report(), already follows this convention.
Return ret like the other HID transport drivers do.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Francesco Lavra <flavra@baylibre.com>
commit bf1e90189a98ca4a824fd64b4f3c6043d13c98ea upstream.
When a USB host suspends a connected device, the DWC2 USB device controller
enters a partial power down state where controller registers are not
accessible. If the USB gadget is then disconnected or deactivated
(e.g. when a gadget function is unbound from the controller), the `pullup`
callback in struct usb_gadget_ops is invoked; if the controller is kept in
partial power down, the register write in dwc2_hsotg_core_disconnect() does
not take effect; as a result, the USB host keeps seeing the device as
connected, even though the device is disabled.
Properly exit partial power down state in the pullup callback, so that the
USB host detects a device disconnection as intended.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 80574c40598aedbc1751c528e414d7e224bc6313 upstream.
A recent change enabling compile testing of a Freescale dual-role
controller indirectly enabled a USB PHY driver to be built. That driver
in turn is missing a bunch of static keywords which results in warnings
like:
drivers/usb/phy/phy-fsl-usb.c:105:5: error: no previous prototype for 'write_ulpi' [-Werror=missing-prototypes]
105 | int write_ulpi(u8 addr, u8 data)
| ^~~~~~~~~~
which consequently breaks -Werror builds.
Add the missing static keywords.
Fixes: 0807c500a1a6 ("USB: add Freescale USB OTG Transceiver driver")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sonali Pradhan <sonalipradhan@google.com>
commit 858965947081d10d41d9a1010a540d3d5eea958b upstream.
g_audio_cleanup() invokes snd_card_free_when_closed() to initiate sound
card teardown and immediately frees the underlying struct snd_uac_chip
context. However, snd_card_free_when_closed() returns asynchronously
while ALSA control elements (kctls) remain open in userspace.
When userspace control applications access or close these open file
descriptors, kctl callbacks attempt to dereference kctl->private_data
pointing to &uac->c_prm or &uac->p_prm within the freed uac structure,
resulting in a use-after-free (UAF) memory corruption.
Fix this issue by deferring the destruction of struct snd_uac_chip until
all references to the ALSA sound card are released. Register a custom
card->private_free callback (u_audio_card_free) during g_audio_setup()
that frees uac and its associated playback/capture request and ring
buffers only when the sound card reference count drops to zero.
Fixes: 6c67ed9ad9b8 ("usb: gadget: u_audio: don't let userspace block driver unbind")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Myeonghun Pak <mhun512@gmail.com>
commit 886338ea7d40e4ba5123c58204d7f7e53d825825 upstream.
When the referenced extcon device has not registered yet,
extcon_get_edev_by_phandle() returns -EPROBE_DEFER after the driver has
initialized and powered on the PHY. The direct return bypasses the common
cleanup path and leaves both operations unbalanced.
Store the lookup error first and route deferred probing through exit_phy,
while retaining the existing behavior of suppressing the error message for
deferral.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yun Zhou <yun.zhou@windriver.com>
commit 9dbf74f4022f80f7669d2b3c22c5deb46c1b5674 upstream.
usbg_make_tpg() held dep_lock while calling
configfs_depend_item_unlocked(), which acquires the configfs root
inode lock when operating across subsystems. This creates a circular
lock dependency with configfs_rmdir():
dep_lock -> configfs root inode lock -> su_mutex -> dep_lock
In usbg_make_tpg(), dep_lock only serialized the read of opts->ready,
which is a monotonic flag that transitions from false to true exactly
once (in tcm_set_name()) and never reverts. Remove dep_lock from
usbg_make_tpg() entirely and use READ_ONCE/WRITE_ONCE to access
opts->ready locklessly instead.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeffin Philip <jeffinphilip14@gmail.com>
commit bdab5605259ba5d6ff927c1a85cc83eb3ecfdacc upstream.
In uvc_function_bind() error path, we use usb_ep_free_request which
uses uvc->control_req but does not set it to NULL afterwards. Thus,
uvc->control_req is a dangling pointer causing a UAF. Also we do not set
the uvc->control_buf pointer to NULL after freeing it, which is another
dangling pointer. Fix it by setting uvc->control_req to NULL after we run
usb_ep_free_request() and uvc->control_buf to NULL after kfree. Do the
same for uvc_function_unbind().

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Neill Kapron <nkapron@google.com>
commit 569dd7e5dcffe1e1c6b26ca2cd3be57eb433e082 upstream.
Currently, ffs_ep0_read() holds ffs->mutex when it prepares to go to
sleep waiting for an event. When no setup events are pending, it calls
wait_event_interruptible_exclusive_locked_irq() with the mutex still
held. The wait macro deliberately drops the waitqueue spinlock before
sleeping but does not drop the mutex.
If a userspace daemon is polling ep0 via read() and the gadget is
asynchronously torn down via configfs (e.g., echo "" > UDC), a
deadlock can occur:
1. The configfs teardown calls functionfs_unbind(), which queues a
FUNCTIONFS_UNBIND event.
2. The daemon wakes up, consumes the event, and drops the mutex.
3. However, if the daemon loops and immediately issues another read()
before exiting, it reacquires ffs->mutex and again goes into an
interruptible sleep.
4. Meanwhile, functionfs_unbind() continues execution and attempts to
acquire ffs->mutex to tear down ep0req.
5. The kernel deadlocks because the configfs thread is stuck in an
uninterruptible sleep waiting for the mutex, while the userspace
daemon is in an interruptible sleep holding the mutex forever
because no more events will arrive.
To fix this, we drop both the waitqueue spinlock and ffs->mutex before
going to sleep, and use wait_event_interruptible_exclusive() instead.
Upon waking up, we jump back to the `retry` label to safely reacquire
the mutex and re-evaluate the state machine. By not sleeping with
ffs->mutex held, we natively decouple gadget teardowns (which require
the mutex) from userspace polling.

------------------
From: Daisuke Matsuda <matsuda@preferred.jp>
commit 9da70a43b5fea60d758137f7f0ccfe19356cb5bb upstream.
The trailing byte path in altera_cvp_send_block() dereferences a u32
pointer even when only 1-3 bytes remain in the input buffer. If the buffer
ends at a page or scatterlist boundary, this can read past the valid image
data and fault.
Copy the remaining bytes into a zero-initialized u32 before writing the
final word so only valid bytes are read from the input buffer.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xingrui Li <baka9@bakabaka9.tech>
commit c92693f3ed099401d0383ef35ca1fe1e6ba033de upstream.
sensor_hub_get_feature() clamps its return value to the caller's buffer
size, but the copy loop still copies field->report_size / 8 bytes for
each report value. A malicious HID descriptor can advertise a large
feature field size while an IIO caller supplies a small stack buffer,
such as a single s32, causing an out-of-bounds write.
HID core stores parsed report values in __s32 slots and clamps extracted
values to 32 bits. Reject feature fields that require more than one slot
per value, guard the total byte count calculation, and clamp each
per-value copy to the remaining caller buffer.

------------------
From: Vincent Mailhol <mailhol@kernel.org>
commit cec0d03fe785380540dc1b4d07c80f67ae2ffc78 upstream.
Patch series "lib/ucs2_string.c: fix out-of-bounds read in
ucs2_strnlen()", v2.
This series fixes an off-by-one out-of-bounds read in ucs2_strnlen().
The first patch is the real fix, the second patch comes as a bonus and
fixes the code indentation.
This patch (of 2):
ucs2_strnlen() checks the current character before checking whether the
caller-provided maximum length has been reached. If the input is not
NUL-terminated within that bound, the loop can read one ucs2_char_t past
the limit.
Test the length before dereferencing to prevent an off-by-one
out-of-bounds read.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Weigang He <geoffreyhe2@gmail.com>
commit fb9dda38d4b9e90db07ed9a0ee2d35bf85494035 upstream.
stm32_rx_done() appends each received CEC byte to rx_msg.msg[] using
rx_msg.len as the write index, incrementing it on every RXBR
(receive-byte-ready) interrupt without checking it against the buffer
size:
cec->rx_msg.msg[cec->rx_msg.len++] = val & 0xFF;
rx_msg.msg[] is a fixed CEC_MAX_MSG_SIZE (16) byte array in struct
cec_msg, and rx_msg.len is only reset on RXACKE/RXOVR or after a
completed message (RXEND). The number of bytes received before RXEND is
decided by the remote CEC device (it sets EOM), not by the driver. A
peer that keeps sending bytes without ending the message drives RXBR
repeatedly, pushing rx_msg.len past 16 and writing peer-controlled bytes
out of bounds into the surrounding memory. This is reachable in normal
operation once the driver has probed and receiving is enabled, from the
IRQ thread, without any local privilege.
The length check in the CEC core runs on the consumer side, after the
byte has been stored, so it does not prevent the overflow. Bound the
index in the driver before the store, as the other platform CEC drivers
already do (e.g. tegra_cec), dropping the excess bytes of an overlong
frame.
Found by static analysis tool CodeQL.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Junrui Luo <moonafterrain@outlook.com>
commit cf4500ebf6fb57bf4ab83c3dd349a40257dbe2a9 upstream.
vidioc_s_fmt_vid_out() sizes the encoder CAPTURE buffer from the
compressed descriptor pixfmt_fwht, whose sizeimage_mult is 3:
coded_w * coded_h * 3 + sizeof(struct fwht_cframe_hdr). fwht_encode_frame()
encodes one plane per component, and an incompressible plane takes the
FWHT_FRAME_UNENCODED path in encode_plane(), copying the plane verbatim.
For a 4-component pixel format all four planes are full resolution
(width_div == height_div == 1), so a frame that forces every plane
through the unencoded fallback writes
sizeof(struct fwht_cframe_hdr) + 4 * coded_w * coded_h bytes, overrunning
the plane by coded_w * coded_h, which can result in corruption
of adjacent kernel heap memory.
Bump pixfmt_fwht.sizeimage_mult from 3 to 4, matching the largest
components_num among the supported raw formats, so the capture buffer is
always large enough for the unencoded fallback.
Fixes: 16ecf6dff97c ("media: vicodec: Add support for 4 planes formats")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
commit 45662dedb8f272ef7f16e69f13424c4bd0399240 upstream.
Shuangpeng Bai reported that KASAN detected a slab-out-of-bounds error
in nilfs_direct_propagate() during testing.
Analysis revealed that after truncating a file, a node block immediately
below the B-tree root was not deleted. Instead, it remained in the B-tree
node cache in a dirty state. The log writer subsequently detected this
block and incorrectly invoked nilfs_direct_propagate() on it, which is
designed to handle only data blocks in direct mapping.
B-tree nodes in the cache are managed by virtual block numbers, and their
logical keys typically exceed the range expected by direct mapping.
Consequently, processing such a node as a direct mapping entry triggers
a slab-out-of-bounds access.
The root cause is that when a B-tree mapping collapses into a direct
mapping during truncation, an intermediate node block pointed to by the
root node is left behind as garbage instead of being explicitly deleted.
This resolves the issue by adding a nilfs_btree_discard() operation
to delete the remaining intermediate node block during the conversion.
A 'deform' flag is added to the bop_delete interface to explicitly signal
that the deletion is part of a mapping transformation. This allows the
B-tree mapping implementation to perform the necessary cleanup and
discarding of the residual node structure that would be otherwise be left
orphaned after the transition.

commit 5bb01c657ff9fc807c2c592ca18af34c4fc3bc6f upstream.
The stem parser tests isdigit(*(end - 1)) before checking end > start
and so reads one byte before the property name when the name is empty
or all digits. Check the bound first.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ibrahim Hashimov <security@auditcode.ai>
commit 95d27c1708bb6e8823c8e7c623f9abc2a91bf4bf upstream.
ubifs_sb_verify_signature() bounds the on-disk ubifs_sig_node->len field
before handing the signature payload to verify_pkcs7_signature(), but the
check has the wrong sign:
if (le32_to_cpu(signode->len) > snod->len + sizeof(struct ubifs_sig_node))
The signature bytes start sizeof(struct ubifs_sig_node) (UBIFS_SIG_NODE_SZ,
64 bytes) into the node, so the payload is at most
snod->len - sizeof(struct ubifs_sig_node)
bytes long. Adding the header size instead of subtracting it accepts a
declared length up to 2 * UBIFS_SIG_NODE_SZ larger than the node actually
holds -- past the end of c->sbuf, which is vmalloc(c->leb_size).
verify_pkcs7_signature() -> pkcs7_parse_message() -> asn1_ber_decoder()
is then handed that inflated length and reads beyond the allocation while
walking the DER headers. The node length comes straight from the mounted
image, so a crafted signed UBIFS image reaches this via
ubifs_read_superblock() before the signature is cryptographically checked.
snod->len is guaranteed to be >= UBIFS_SIG_NODE_SZ by the node scanner
(c->ranges[UBIFS_SIG_NODE].min_len == UBIFS_SIG_NODE_SZ), so the corrected
subtraction cannot underflow. Legitimately signed images are unaffected: a
correct superblock never declares a signature longer than the node it is
embedded in.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuck Lever <cel@kernel.org>
commit ed4edddad19babf76b56882ad9600f5646b167a0 upstream.
The NFSv2 ACL GETACL reply is a union that carries file attributes
and ACL data only when the status is NFS_OK. All error cases are
void results. However, currently the NFSv2 ACL GETACL result encoder
decides whether to append the "OK" body by testing only whether the
file handle resolved to a positive dentry, not the actual reply
status.
A GETACL request that resolves its file handle but then fails for
another reason (an unsupported mask value, a getattr failure, or an
ACL retrieval error) therefore appends file attributes and ACL data
after the error status on the wire. Worse, when the mask is
rejected, fh_getattr() hasn't been called at all, so those
attributes are serialized from a zero-filled kstat and are junk.
The logic before the xdr_stream conversion used the reply status.
Revert to that approach (but keep the xdr_stream conversion in
place).

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Bommarito <michael.bommarito@gmail.com>
commit 036c1b182f4da65363e79ec0ac276edc6b7296e5 upstream.
nfsd4_ssc_expire_umount() walks nn->nfsd_ssc_mount_list with
list_for_each_entry_safe(ni, tmp, ...). For each expired entry it
sets nsui_busy = true, drops nfsd_ssc_lock to run mntput() on the
source vfsmount, then reacquires the lock to list_del + kfree the
entry and continue iterating via the macro's saved tmp pointer.
The nsui_busy flag protects the current ni from concurrent
nfsd4_ssc_setup_dul() finders during the lock-drop window, but it
does not pin tmp. Another nfsd RPC thread that fails its source-
server mount and reaches nfsd4_ssc_cancel_dul() will, during that
same window, take nfsd_ssc_lock, list_del + kfree its own ssc_umount
item, and release the lock. If that item is the saved tmp of the
expire walk, the next iteration dereferences a freed
nfsd4_ssc_umount_item.
Restart the walk from the head after the mntput() unlock window so
no saved next pointer survives the lock-drop. The list is bounded
by the number of active inter-server source mounts (typically small)
and the expire delayed-work runs periodically rather than per-IO,
so the restart is cheap.
Fixes: f4e44b393389 ("NFSD: delay unmount source's export after inter-server copy completed.")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mike Snitzer <snitzer@kernel.org>
commit aa0cf48a448c5a9fe1a1e880899ecd589ce39e6e upstream.
The header for commit e75b23f9e323 ("nfsd: check d_can_lookup in
fh_verify of directories") details the assumption that justified
adding the WARN_ON_ONCE to nfsd_mode_check(), that assumption is
invalid (in the case of NFS reexport).
When NFSD exports an NFS filesystem it is very possible for
nfsd_mode_check() to encounter a @dentry that doesn't have
i_op->lookup (see nfs_fhget()'s NFS_ATTR_FATTR_MOUNTPOINT and
NFS_ATTR_FATTR_V4_REFERRAL handling, and d_flags_for_inode()).
So remove nfsd_mode_check()'s WARN_ON_ONCE(). The nfserr_notdir
return on that branch must stay. It guards the subsequent
lookup_one_unlocked() -> __lookup_slow() path, which calls
inode->i_op->lookup() with no NULL check, so returning nfserr_notdir
is what keeps a client LOOKUP into such a @dentry from dereferencing
a NULL method pointer.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Junrui Luo <moonafterrain@outlook.com>
commit ee5a386cfe60f3f8286de16a9db8e1a08f0bc124 upstream.
When the server returns a new layout stateid while a valid one is still
held, pnfs_layout_process() calls pnfs_mark_matching_lsegs_return() on
the on-stack free_me list and jumps to out_forget. Segments whose
reference count drops to zero are unlinked from lo->plh_segs and moved
to free_me by mark_lseg_invalid(); for an idle cached segment the layout
header holds the only reference, so this happens on the first decrement.
out_forget never drains free_me -- only the success path calls
pnfs_free_lseg_list().
Commit 814b84971388 ("pNFS/NFSv4: Fix a layout segment leak in
pnfs_layout_process()") added the drain; commit 08bd8dbe8882
("pNFS/NFSv4: Try to return invalid layout in pnfs_layout_process()")
removed it while switching the destination to lo->plh_return_segs, which
is drained elsewhere. Commit fb700ef02676 ("NFSv4.1: Simplify layout
return in pnfs_layout_process()") switched the destination back to
free_me without restoring the drain.
Restore the pnfs_free_lseg_list() call.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuck Lever <chuck.lever@oracle.com>
commit f5cb2276954cb80987a93ef9f9dfbfdbfc0f10b9 upstream.
Async COPY captures nn->writeverf at request time and reports it to
the client via CB_OFFLOAD after the worker kthread completes. When
the post-copy vfs_fsync_range() or filemap_check_wb_err() in
_nfsd_copy_file_range() reports an error, the worker correctly
leaves NFSD4_COPY_F_COMMITTED clear so that CB_OFFLOAD encodes
wr_stable_how as NFS_UNSTABLE, but the server's write verifier is
not rotated.
A client that receives NFS_UNSTABLE in CB_OFFLOAD follows up with
COMMIT to make the copied data durable. With the verifier
unchanged, COMMIT returns the same value the client just received
via CB_OFFLOAD, and the client concludes the copy is durable --
silently dropping the data whose writeback in fact failed. This
violates the UNSTABLE+COMMIT durability contract (RFC 7862 section
15.1, RFC 8881 section 18.32) and matches the bug just fixed in
nfsd_vfs_write() and nfsd_commit().
Rotate nn->writeverf at the writeback-failure site. The async COPY
worker has no svc_rqst, so commit_reset_write_verifier() is not
available here; calling nfsd_reset_write_verifier() directly
mirrors the trace-less reset already used by
nfsd_file_check_write_error() for the same purpose. Filter out
-EAGAIN and -ESTALE, matching commit_reset_write_verifier(), since
neither indicates a durable-storage failure.

commit 45b06a75086f331f52cbb81223a59421d43f8809 upstream.
nfsd4_decode_nl4_server() handled only NL4_NETADDR and returned
nfserr_bad_xdr for NL4_NAME and NL4_URL. Those forms are well-formed XDR,
so BADXDR is misleading -- the request is unsupported, not malformed.
Decode and discard the utf8str_cis for NL4_NAME and NL4_URL to keep the
stream consistent, and return nfserr_notsupp. nfsd4_proc_compound() honors
a decode-time op->status, so the op fails without executing.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuck Lever <chuck.lever@oracle.com>
commit 20a67a7d18221af736f124770c2c5e859b479046 upstream.
_nfsd_copy_file_range() samples dst->f_wb_err into "since"
after the copy loop, then uses it to detect writeback errors
via filemap_check_wb_err() once vfs_fsync_range() returns.
Because the nfsd_file cache reuses a single struct file
across requests targeting the same inode, a concurrent
COMMIT or stable WRITE on dst advances dst->f_wb_err to the
current mapping->wb_err via file_check_and_advance_wb_err()
during its own vfs_fsync_range(). If that advancement lands
between the writeback error appearing in mapping->wb_err
and the COPY worker sampling "since", the worker captures
the already-advanced cursor, errseq_check() sees cur ==
since and returns zero, and NFSD4_COPY_F_COMMITTED is set
even though writeback failed. CB_OFFLOAD then encodes
wr_stable_how = FILE_SYNC4, the client treats the copied
data as durable, and the failure becomes silent data loss.
Sample since once at the start of the function. The cursor
then reflects state in effect before this COPY issues any
writes, and filemap_check_wb_err() detects any error that
occurs during the copy regardless of which thread first
observes it. This matches the pattern used by
nfsd_vfs_write() and nfsd4_clone_file_range().

commit 041f57056e5fb9c80adc088269322d2c61074406 upstream.
nfsd4_decode_create() accepts an unbounded cr_datalen from the wire for
NF4LNK symlink targets, allowing a client to force a kmalloc of up to
the maximum RPC payload size (several MiB) per COMPOUND op that persists
until compound teardown. The VFS rejects oversized targets with
ENAMETOOLONG, but the allocation has already occurred.
Reject cr_datalen == 0 early with nfserr_inval and cr_datalen greater
than NFS4_MAXPATHLEN (PATH_MAX) with nfserr_nametoolong to bound the
allocation.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jlayton@kernel.org>
commit 4e475be769aa9f7a2c1ce55a2b8592cfccacddcc upstream.
The BOTH_TIME_SET branch calls fh_verify() early so setattr_prepare()
can inspect the dentry. This causes nfsd_setattr() to skip
fh_want_write(), so notify_change() runs without a mount write
reference.
Add the missing fh_want_write() call after the early fh_verify().

From: Jeff Layton <jlayton@kernel.org>
commit 04cce9d79f2b1a114f7128e08bf60a473e10f1ec upstream.
nfsd4_delegreturn() is the only stateful NFSv4 operation that does
not call nfs4_check_fh() to verify the delegation's file matches
cstate->current_fh. A client can DELEGRETURN with a mismatched
filehandle, destroying the correct delegation but waking the wrong
inode's waiters.
Add the missing nfs4_check_fh() call after the generation check.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jlayton@kernel.org>
commit c59738a00aa51b16adc1b5ceb7c80877168efb4d upstream.
When CONFIG_NFSD_V4_2_INTER_SSC is enabled, nfsd4_putfh() can return
success with fh_dentry and fh_export both NULL if fh_verify() returns
nfserr_stale and putfh->no_verify is true. The NFSD4_FH_FOREIGN flag
is set, but the compound dispatch loop only uses this flag to bypass
the nfserr_nofilehandle check -- it does not prevent subsequent ops
from running with a NULL fh_dentry.
A remote client can exploit this by crafting a COMPOUND that includes
an inter-SSC COPY (which causes check_if_stalefh_allowed() to set
no_verify=true on the saved PUTFH) with an additional op inserted
between the source PUTFH and SAVEFH. For example, SETATTR calls
fh_want_write() which dereferences fh_export->ex_path.mnt without
calling fh_verify() first, causing a NULL pointer dereference in the
nfsd kthread.
Fix this by gating the dispatch loop: when NFSD4_FH_FOREIGN is set
and fh_dentry is NULL, only OP_SAVEFH (needed for the inter-SSC flow)
and ops with ALLOWED_WITHOUT_FH (which don't need a resolved
filehandle) may proceed. All other ops receive nfserr_stale, per
RFC 7862 Section 15.2.3 which specifies that foreign filehandle
validation is deferred to the consuming operation and NFS4ERR_STALE
returned at that point.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jlayton@kernel.org>
commit 6bdbfab96e0cf25e5f57dac5c09dc1749751a4bf upstream.
On the OFFLOAD_CANCEL path (clp != NULL), manage_cpntf_state() freed the
target cpntf state without checking ownership. The lookup key
st->si_opaque.so_id is allocated cyclically (guessable) and the embedded
clientid is the fixed per-net nn->s2s_cp_cl_id, so any authenticated
NFSv4.2 client could cancel and free another client's copy-notify
stateid.
Compare the creating clientid recorded in state->cp_p_clid against the
requesting client's cl_clientid and return nfserr_bad_stateid on a
mismatch instead of freeing the entry.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chris Mason <clm@meta.com>
commit be3a5c1d857b0dcbc11796cea603ef25834f75b2 upstream.
nfs4_alloc_init_cpntf_state() published the new cpntf entry into the
s2s_cp_stateids IDR (with cs_type set) in one s2s_cp_lock section, then
took the lock again to list_add() it onto p_stid->sc_cp_list. In the gap
the entry is reachable by so_id but cp_list is still {NULL,NULL} from
kzalloc. A racing OFFLOAD_CANCEL (so_id is echoed to the client as
cnr_stateid, so any NFSv4.2 client can drive it) reaches
manage_cpntf_state() -> _free_cpntf_state_locked() and does list_del() on
the zeroed list_head, oopsing the server.
Fold the cs_type assignment and the list_add() into the same critical
section as idr_alloc_cyclic(), so a concurrent lookup either misses the
entry or sees a fully linked cp_list. INIT_LIST_HEAD() the entry after
allocation and switch _free_cpntf_state_locked() to list_del_init() so a
stale unlink is a no-op. nfs4_init_copy_state() passes NULL p_stid and
skips the list_add, preserving NFS4_COPY_STID semantics.

commit 9bc761051dcd9a4a8b59e64b2b185172d13c716d upstream.
The loops that compute the supported version range for PROG_MISMATCH
test nfsd_support_acl_version(rqstp->rq_vers) instead of
nfsd_support_acl_version(i), so every iteration fails and the
function returns rpc_prog_unavail instead of rpc_prog_mismatch.
Replace rqstp->rq_vers with the loop variable i, matching the
pattern used by the sibling nfsd_init_request() function.

The XDR buffer size calculation in nfsd4_ff_encode_layoutget() has
multiple errors that can result in either an out-of-bounds write or
leaking uninitialized kernel memory to the client:
- fh_len doesn't account for XDR padding on the file handle data
- uid and gid lengths use "8 + len" but xdr_encode_opaque() actually
writes "4 + xdr_align_size(len)" bytes
- ds_len omits the flags and stats_collect_hint fields (8 bytes),
while len's header constant overestimates by 8 bytes -- these
partially cancel but leave a net mismatch
The worst case occurs with short strings (e.g. uid=0, gid=0 with an
odd-sized file handle), where the function writes up to 5 bytes past
the reserved XDR buffer. Conversely, when string lengths happen to be
4-byte aligned, the reservation is too large and stale buffer content
is sent to the client.
Fix this by breaking out every encoded field explicitly in the ds_len
calculation, using xdr_align_size() for all variable-length opaque
fields, and correcting the header constants.

------------------
From: Jeff Layton <jlayton@kernel.org>
commit 8b989aaec85e1293a871d602590c951fe44b8647 upstream.
nfsd4_ff_encode_getdeviceinfo() computes the da_addr_body reservation
as 16 + netid_len + addr_len, but the subsequent xdr_encode_opaque()
calls emit 8 + round_up(netid_len, 4) + round_up(addr_len, 4) bytes.
The mismatch means the declared da_addr_body length exceeds the actual
encoded data by 2-8 bytes on every flexfile GETDEVICEINFO reply,
leaking stale reply-page content to the client and mis-aligning the
subsequent version list decode.
Use xdr_align_size() for each string length to match what
xdr_encode_opaque() actually writes.

------------------
From: Jeff Layton <jlayton@kernel.org>
commit 129643893b79f8a3c6b72045f933fbab5ee424ca upstream.
nfsd4_copy_notify() finished initializing the cpntf state after
nfs4_alloc_init_cpntf_state() had already linked it into the
s2s_cp_stateids IDR and the parent's sc_cp_list, with cs_count == 1 (the
membership reference) and none held for the caller. A racing
OFFLOAD_CANCEL (crafted cl_id == nn->s2s_cp_cl_id plus the guessable
so_id) could reach manage_cpntf_state() and free the entry, turning the
caller's subsequent cpn_cnr_stateid read and cp_p_stateid/cp_p_clid
writes into use-after-free. The owning clientid was also only recorded
after publication, so it could not gate an ownership check in that window.
Record cp_p_stateid and cp_p_clid inside nfs4_alloc_init_cpntf_state()
before nfs4_init_cp_state() publishes the entry, and return it with an
extra reference. The caller reads the stateid under that reference and
drops it with nfs4_put_cpntf_state(); on a late error the laundromat
reaps the entry.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robbie Ko <robbieko@synology.com>
commit 26709c8ffe73772eb69e68d553ac71d91228dccc upstream.
The NFSv2 sattr decoder converts the wire useconds to nanoseconds in
svcxdr_decode_sattr():
iap->ia_atime.tv_nsec = tmp2 * NSEC_PER_USEC;
tmp2 is a u32 and NSEC_PER_USEC is 1000, so the product is computed in
unsigned long. On ILP32 that is 32 bits, and an out-of-range useconds
value such as 4294968 wraps to tv_nsec == 704. The corruption therefore
happens during decode, before any proc function can inspect the value,
and a later range check on tv_nsec would see an in-range result and
accept it. Rejecting in the decoder yields an RPC GARBAGE_ARGS reply.
NFSv2 defines no NFSERR_INVAL, so there is no NFS-level status to return
for a malformed time argument, and the check cannot move to the proc
function the way the v3/v4 nsec range checks do.
Guard the raw useconds before the multiplication and reject values
greater than 1000000. useconds == 1000000 is kept: it is the Sun
convention for "set to the current server time", and the in-tree Linux
NFSv2 client emits it in both the atime and the mtime field for a plain
touch / utimes(file, NULL) (see encode_sattr() and
xdr_encode_current_server_time() in fs/nfs/nfs2xdr.c). Rejecting 1000000
would turn that common operation into a hard decode failure for both
SETATTR and CREATE. 1000000 * NSEC_PER_USEC is 10^9, which does not wrap
on ILP32, so the Sun convention value passes through safely. Only
genuinely out-of-range values (> 1000000) are rejected. The atime and
mtime guards are therefore symmetric.
The decoder only applied the Sun convention in the mtime block, which
clears ATTR_ATIME_SET|ATTR_MTIME_SET when mtime useconds == 1000000. If a
client puts 1000000 in the atime field but not in the mtime field, the
atime block stored an out-of-range tv_nsec (10^9) and left ATTR_ATIME_SET
set, so the bogus value reached the filesystem. Apply the convention in
the atime block as well, clearing ATTR_ATIME_SET so the server uses its
current time and ignores the value. Only ATTR_ATIME_SET is cleared there.
The mtime block keeps its existing behavior, where 1000000 means "set
both atime and mtime to now".

------------------
From: Jeff Layton <jlayton@kernel.org>
commit 2327ba1d9546727a35b17888777e991f68a9b305 upstream.
nfsd4_lock() only checks the namespace-wide grace flag when deciding
whether to accept a reclaim LOCK. It does not check the per-client
NFSD4_CLIENT_RECLAIM_COMPLETE bit. An NFSv4.1+ client that has
already sent RECLAIM_COMPLETE can submit lk_reclaim=1 while grace is
still active (e.g. lockd holds the grace list open), and the server
accepts it instead of returning NFS4ERR_NO_GRACE as required by
RFC 8881 section 18.51.3.
The OPEN path already enforces both tiers: the grace check plus the
per-client RECLAIM_COMPLETE check in nfs4_check_open_reclaim(). Add
the equivalent per-client check to the LOCK path.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jlayton@kernel.org>
commit 3b0c3595db99bb4bebd7c8aa8a36f3c50e411bb7 upstream.
Copy-notify stateids live in the s2s_cp_stateids IDR and on their parent
stid's sc_cp_list, pinned by a single membership reference.
_free_cpntf_state_locked() only unlinks an entry once its refcount reaches
zero, so any revoke path that runs while a concurrent
find_cpntf_state()/manage_cpntf_state() holder has elevated cs_count drops
the reference without unlinking, leaving the entry discoverable with its
membership reference already consumed. A second revoke or a laundromat tick
then frees it while the reader still holds the pointer -- a
KASAN-detectable use-after-free at the reader's nfs4_put_cpntf_state().
This affected all three revoke paths:
- The parent-stid drain (nfs4_free_cpntf_statelist()) repeatedly called
_free_cpntf_state_locked() on the first list entry; a holder that had
bumped cs_count made it return early, so the next iteration
re-decremented and burned the holder's reference.
- OFFLOAD_CANCEL (manage_cpntf_state()) and laundromat expiry likewise
used _free_cpntf_state_locked() and could drop 2->1 without unlinking.
Add revoke_cpntf_state_locked(), which unhashes the entry from the IDR and
sc_cp_list first (deferring the final free to any holder), and use it from
all three revoke paths. The drain now walks with list_for_each_entry_safe()
and revokes each entry unconditionally, so it terminates in one pass per
entry regardless of cs_count. The unhash is gated on
!list_empty(&cps->cp_list); the idr_remove() gate matters because
idr_alloc_cyclic() may have recycled the so_id by then. Keep
_free_cpntf_state_locked() for the reference-holder put path only, where a
concurrent revoke may already have unlinked the entry (its list_del_init()
then a no-op).

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuck Lever <cel@kernel.org>
commit 5e2fa29d223a9a1e6a948e40b109d09081d1decd upstream.
__destroy_client() releases a client's open owners, but a lock owner
whose only reference is a blocked lock (nbl) stays on
cl_ownerstr_hashtbl. client_has_state() does not count a bare owner,
so DESTROY_CLIENTID can reach __destroy_client() with such owners
present.
__destroy_client() then walks the table, calling remove_blocked_locks()
on each owner without a reference. Freeing a blocked lock drops the
owner reference held via flc_owner. The per-net laundromat reaps
blocked locks from nn->blocked_locks_lru independently of client state.
The two paths share blocked_locks_lock only for the list splice, not
the owner's lifetime. The laundromat therefore frees the owner as
__destroy_client() dereferences it, a NULL dereference in
remove_blocked_locks().
nfsd4_release_lockowner() holds a reference across the same call;
__destroy_client() does not. Hold cl_lock across the walk, taking a
reference and unhashing each owner, then drop it before
remove_blocked_locks() and nfs4_put_stateowner(), which take
blocked_locks_lock and cl_lock.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jérémy Jean <Jeremy.Jean@oss.cyber.gouv.fr>
commit 3cde4a8302301679937474a5f7a851394cc1bd11 upstream.
crush_decode() stores bucket data by array slot, and the mapper later
derives the per-bucket workspace index from the decoded bucket id. A
malformed map can therefore make one bucket reuse another bucket's
workspace by encoding an id different from -1 - slot.
For uniform buckets, the second replica selection expands the source
bucket's permutation into that aliased workspace buffer. If the source
bucket is larger than the aliased bucket, the write runs past the smaller
permutation array and can escape the kvmalloc'd CRUSH workspace. KASAN
reports a slab OOB write of 4 bytes in bucket_perm_choose().
Reject buckets whose encoded id does not match their array slot. Valid
CRUSH maps already use the canonical negative id corresponding to the
bucket slot, so this restores the invariant expected by
work->work[-1 - in->id] without changing valid map behavior.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xiubo Li <xiubo.li@clyso.com>
commit 7af4c4f01305b0935adf6d4301b1ec407025485d upstream.
list_for_each_entry() iterates ci->i_cap_flush_list but drops
i_ceph_lock to send cap messages. During the unlock window,
handle_cap_flush_ack() can acquire i_ceph_lock, detach cf entries
with tid <= flush_tid from the list, release i_ceph_lock, and free
them via ceph_free_cap_flush() outside any lock. When the original
thread reacquires i_ceph_lock and the for-loop macro advances via
cf = list_next_entry(cf, i_list), it dereferences cf->i_list.next
on freed memory.
The race timeline:
__kick_flushing_caps() handle_cap_flush_ack()
----------------------- -----------------------
holds i_ceph_lock <---
iterates to cf (tid=10)
prepares FLUSH message
drops i_ceph_lock <---
__send_cap() ── FLUSH(tid=10)
MDS sends FLUSH_ACK(tid=10)
---> acquires i_ceph_lock
cf->tid(10) <= flush_tid(10),
detaches cf from i_cap_flush_list
drops i_ceph_lock
ceph_free_cap_flush(cf) <- frees it!
acquires i_ceph_lock <---
for-loop advances:
cf = list_next_entry(cf, i_list)
-- UAF on freed cf->i_list.next
The cf was just sent by __kick_flushing_caps itself via __send_cap().
The MDS may respond with FLUSH_ACK quickly enough that
handle_cap_flush_ack() frees cf before __kick_flushing_caps can
finish the iteration.
Fix by converting to a manual while loop: save the next pointer
under i_ceph_lock before dropping it, then use the saved pointer
after reacquiring, so the potentially-freed cf is never accessed again.

commit aedc9053d909508a5f56c3f49f885fc030df4730 upstream.
MDSMap export_targets entries are monitor controlled. check_new_map()
uses each entry as a bit number in a fixed stack bitmap, so a rank
outside the protocol namespace can make set_bit() write past the end of
the array.
Reject ranks outside CEPH_MAX_MDS while decoding the map. Do not
validate against possible_max_rank here because maps may legitimately
reference ranks beyond a temporarily reduced max_mds.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Bommarito <michael.bommarito@gmail.com>
commit a3eb169ee297aa99670ba927c659990bd1e453f3 upstream.
ceph_mdsmap_decode() in fs/ceph/mdsmap.c reads num_export_targets from
each per-mds info record and advances the decode cursor by
num_export_targets * sizeof(u32) without first checking that many bytes
remain. The only upper-bound check that catches a runaway cursor
(*p > info_end) is gated on info_v >= 4, because info_end is left NULL
for info_v 2 and 3. When the monitor sends an MDS map whose per-mds
info version is 2 or 3 with an oversized num_export_targets, the cursor
moves past the message front buffer and the later export-targets loop
calls the unchecked ceph_decode_32() on out-of-bounds memory.
A kernel client processes CEPH_MSG_MDS_MAP from its monitor session
(net/ceph/mon_client.c dispatches it; fs/ceph/super.c routes it to
ceph_mdsc_handle_mdsmap(), which sets end to the front buffer bound and
calls ceph_mdsmap_decode()). A malicious or compromised monitor, or an
on-path attacker on an unsigned/unencrypted messenger session, can
therefore drive an out-of-bounds read in the client kernel; on x86_64
with KASAN it is reported as a slab-out-of-bounds read in
ceph_mdsmap_decode(). The decoded values land in the internal
info->export_targets[] array, so the consequence is a kernel
out-of-bounds read, not an information leak to the attacker.
Impact: a malicious or compromised Ceph monitor sending an MDS map with
a per-mds info version of 2 or 3 and an oversized num_export_targets
field triggers an out-of-bounds read in the CephFS client kernel.
Add a ceph_decode_need() for the export-targets array before advancing
the cursor, so the bound is enforced for every info_v >= 2, not only
info_v >= 4. This mirrors the count-then-need idiom already used for
m_data_pg_pools later in the same function.
Compute the export-targets byte count with size_mul() and reuse that
checked length when advancing the cursor, so the attacker-controlled
num_export_targets multiplication fails closed on overflow rather than
relying on the later kcalloc() guard.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Bommarito <michael.bommarito@gmail.com>
commit 68d541754d6cd3bb98d1fd8314f57e5eb533557d upstream.
__build_xattrs() decodes the MDS-supplied xattr blob one attribute at a
time. For each attribute it reads a 32-bit name length, advances past the
name bytes, reads a 32-bit value length, records the value pointer, and
advances past the value bytes. The two length fields are read with
ceph_decode_32_safe(), but the value bytes themselves are advanced over
with a bare "p += len" and no ceph_decode_need() check that "len" bytes
remain in the blob.
For every attribute except the last, the next iteration's
ceph_decode_32_safe() on the following name length implicitly verifies
that the previous value did not run past the blob end. The final
attribute has no successor, so its decoded value length is never checked
against the blob bounds. A malicious or compromised metadata server can
set the last attribute's value length larger than the bytes actually
present in the blob.
The blob is a dedicated kvmalloc() allocation sized to the wire length
(ceph_buffer_new() in ceph_fill_inode()). __set_xattr() records the
oversized length in xattr->val_len verbatim, and a later getxattr(2) runs
memcpy(value, xattr->val, xattr->val_len) into a user-supplied buffer,
copying bytes past the end of the allocation back to user space.
Impact: a malicious metadata server discloses adjacent kernel heap bytes
to a local user via getxattr(2) on a CephFS file. Add the missing
ceph_decode_need() so an out-of-bounds value length on the final
attribute fails the decode and returns -EIO instead of being stored.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jérémy Jean <Jeremy.Jean@oss.cyber.gouv.fr>
commit 783f0f0974c156aca630f4ffff248671082a098d upstream.
audit_del_rule() is used for both netlink deletion templates and internal
fsnotify autoremove. The former passes a parsed template which owns a
temporary tree reference; the latter passes the installed entry itself.
The unconditional audit_put_tree() at the end of audit_del_rule() assumes
the template case. For mixed AUDIT_DIR plus AUDIT_EXE rules, an fsnotify
autoremove event therefore drops the installed rule's live tree reference.
Repeating this across rules sharing the same tree can free the tree while
another rule still references it, and a later autoremove dereferences the
freed pathname while comparing rules.
Move the temporary-tree put to audit_rule_change(), the caller that owns
deletion templates. Keep it in the AUDIT_DEL_RULE cleanup so both
successful deletion and -ENOENT still release the parser-owned tree.

------------------
From: Frank Sorenson <sorenson@redhat.com>
commit 6c322f5cf7476ded7a9a20f7be72462065a03c68 upstream.
With len == 0 (clone to EOF), the effective length is computed as:
len = src_inode->i_size - off;
If off > i_size, this is a negative loff_t, corrupting the ByteCount
in the FSCTL_DUPLICATE_EXTENTS_TO_FILE request and inverting the range
in filemap_write_and_wait_range(). The existing off >= i_size check
fires only after the ioctl has already been sent.
Snapshot i_size_read() once for both the bounds check and the length
calculation, eliminating the TOCTOU and 32-bit torn-read risk. Reject
off > src_size with -EINVAL. Treat off == src_size as a no-op,
consistent with __generic_remap_file_range_prep().

From: Fredric Cover <fredric.cover.lkernel@gmail.com>
commit b1b741cf8e7ce1b91d937e23decd3d3358748700 upstream.
When free_tgts() frees all structures in ce->tlist, ce->tgthint
is left pointing to one of the freed cache_dfs_tgt structures.
If ce->tgthint is not reset before it is used later, it results
in a use-after-free.
Set ce->tgthint to NULL in free_tgts() after the elements are
freed to reflect that no elements remain.

------------------
From: Frank Sorenson <sorenson@redhat.com>
commit 62656b024efc21c3230eade1a847f25871c3d2bb upstream.
The check added by commit 7d9a7f1f96cd ("smb/client: fix possible
infinite loop and oob read in symlink_data()") compared the post-ALIGN
length against the remaining buffer, but ALIGN() itself can overflow:
for ErrorDataLength near UINT32_MAX (e.g. 0xFFFFFFF9), ALIGN(x, 8)
wraps to 0, so the subsequent bounds check passes, and the loop
advances by zero bytes leaving 'p' pointing into stale data.
Fix by checking the raw ErrorDataLength against the remaining space
before applying ALIGN(), then checking again after. Since raw_len is
bounded by the buffer, raw_len + 7 cannot overflow, so the second check
is an exact post-alignment bounds guard.

Currently, get_tgt_name() returns ERR_PTR(-ENOENT) when ce->tgthint is

In preparation for clearing ce->tgthint in free_tgts(), harden callers
of get_tgt_name() against ERR_PTR results and harden
dfs_cache_noreq_update_tgthint() against NULL pointer dereferences.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ibrahim Hashimov <security@auditcode.ai>
commit e9c667395ac1f8024f623250b32bae4c7af9caa0 upstream.
picolcd_debug_eeprom_read() trusts resp->raw_data[2] -- a length byte
supplied by the device in its REPORT_EE_DATA reply -- clamped only to
the caller's read() count:
ret = resp->raw_data[2];
if (ret > s)
ret = s;
if (copy_to_user(u, resp->raw_data+3, ret))
It never checks resp->raw_size, the number of bytes picolcd_raw_event()
actually copied into the 64-byte raw_data[] of the kmalloc'd struct
picolcd_pending. A device (or a spoofed picoLCD) returning a length byte
of 0xff, read with a count >= 255, makes copy_to_user() read past
raw_data[] into adjacent slab memory and return it to userspace through
the debugfs "eeprom" file:
BUG: KASAN: slab-out-of-bounds in _copy_to_user
Read of size 255 ... picolcd_debug_eeprom_read+0x214/0x2f0 [hid_picolcd]
The debug-dump path in the same file already validates the device length
byte against the received size before trusting it; this read does not.
The file is created S_IRUSR (root-only) and a crafted device is needed,
so it is neither unprivileged- nor remotely-triggerable.
Clamp the copy length to resp->raw_size - 3 (the payload actually
received, minus the 3-byte header), floored at 0 for short replies.

commit bbff0ccbff360a5498075525005f6a913239a3d7 upstream.
roccat_report_event() duplicates each report with kmemdup() and stores
the allocation in a circular-buffer slot. The allocation is released only
when that slot is reused.
The device destruction paths free struct roccat_device without releasing
reports still stored in cbuf[]. This makes those allocations unreachable
and leaks up to ROCCAT_CBUF_SIZE report buffers per device.
Add a small destructor that frees every buffered report before freeing the
device, and use it in both paths that can destroy a registered device.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Haoxiang Li <haoxiang_li2024@163.com>
commit 3789d0802ddb4b3be04062caf4bfadd23496e9a7 upstream.
hid_sensor_custom_add_attributes() creates one sysfs group for each
custom sensor field. If sysfs_create_group() fails after some groups
have already been created, the function returns the error without
removing the previously created groups.
Add a local unwind path to remove the groups that were already created.
With enable_sensor exposed only after the field attributes are ready,
this path can free sensor_inst->fields without leaving enable_sensor
able to access pointers into that array.

------------------
From: Jiangshan Yi <yijiangshan@kylinos.cn>
commit 2c9a6998c19503626c57a2267bf279e204113079 upstream.
mcp2221_raw_event() never validates the size of incoming HID reports.
In the MCP2221_I2C_GET_DATA path it trusts the device-supplied data[3]
as the copy length without checking that 4 + data[3] bytes actually
exist in the received report. A malicious or misbehaving USB device can
send a short report with a large data[3], causing the memcpy to read
past the valid report data in the HID transfer buffer and leak
uninitialized kernel memory back to userspace through the I2C/SMBus
read path.
Add a minimum size check at entry and validate that the source range
fits within the received report before the copy.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xiang Mei <xmei5@asu.edu>
commit 006cb7713dec10368e699abc4367e5faa334c9a5 upstream.
Each DIR_PAGE_ENTRY ends in a page_lcns[] array whose length is the on-disk
lcns_follow field. check_rstbl() validates the table bookkeeping but never
checks that this array fits in the entry, so a crafted lcns_follow lets the
v0->v1 conversion memmove and later replay passes run off the entry.
Add check_dp_table() to reject, right after check_rstbl(), any entry larger
than its size claims via struct_size() (the same expression used to allocate
these entries, so the check is overflow-safe by construction). All consumers
can then trust lcns_follow as the real capacity. This covers every
page_lcns[] access whose index is bounded by the entry itself (the
conversion memmove, the HotFix store via find_dp(), and the self-bounded
scan loops). Accesses whose index comes from the log record need a separate
bound and are handled in a follow-up patch.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Samuel Page <sam@bynar.io>
commit 35d1ea92c7d946e2ebdbe36cdb2c969c8704bebd upstream.
ni_read_frame() decompresses an LZNT $DATA frame into the vmapped target
pages and then trusts decompress_lznt()'s return value:
unc_size = decompress_lznt(frame_ondisk, ondisk_size, frame_mem,
frame_size);
if ((ssize_t)unc_size < 0) err = unc_size;
else if (!unc_size || unc_size > frame_size) err = -EINVAL;
decompress_lznt() stops as soon as the compressed stream is exhausted
(e.g. a zero chunk header) and returns the number of bytes it actually
wrote, which may be far less than frame_size. The bytes between unc_size
and frame_size are never written. The only memset() that follows zeroes
the region beyond i_valid; when the frame lies entirely within the file's
valid size that memset() does not run, so the gap retains whatever was in
the just-vmapped pages. All pages are then marked uptodate and returned
to userspace, disclosing uninitialized (recently-freed) kernel page
memory. A crafted compressed file whose stream decompresses to only a few
bytes leaks the remainder of every frame on a plain read(2), which is
enough to recover kernel pointers and defeat KASLR.
Zero the [unc_size, frame_size) tail immediately after a successful LZNT
decompress so the remainder reads back as zero.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
commit 6f7b9dbdc1b7520206abce0049bdd143eb536e75 upstream.
The copy_lcns loop and the redo shorten loop index page_lcns[] at j + i,
where i runs up to the log record's lcns_follow. That count is checked only
against the record's own length, not the target entry, so check_dp_table()
(which validates the entry's lcns_follow) does not cover it: the copy_lcns
entry may even be freshly allocated after that check, and find_dp() bounds j
but not i. A crafted record thus overflows page_lcns[] of an otherwise valid
entry.
Add dp_range_ok() and reject, before each loop, any record whose run does
not fit the entry. These are the only two page_lcns[] accesses indexed by
the record rather than the entry, so together with the entry validation
every access is now bounded.

commit 95540462e630edbc8504e9537d16453d6942d143 upstream.
ecryptfs_miscdev_write() accepts the minimum one-byte packet-length
encoding, but always copies the maximum two-byte encoding from userspace
before parsing it. A six-byte message therefore reads one byte beyond the
submitted user buffer.
Zero-initialize the peek buffer and copy only the packet-length bytes
present. The existing exact packet-size check still rejects truncated
two-byte encodings after the parser determines their encoded length.

parse_tag_11_packet() rejects a packet when the already-consumed tag and
length bytes plus the packet body exceed the caller supplied maximum

*packet_size already includes the tag byte before the length is parsed.
Remove the extra byte so a tag 11 packet that exactly fits the available

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yichong Chen <chenyichong@uniontech.com>
commit 779972513c2fa8c7938e54976f686091dafff22f upstream.
ecryptfs_exorcise_daemon() drops queued messages from a dying daemon
without holding ecryptfs_msg_ctx_lists_mux, but
ecryptfs_msg_ctx_alloc_to_free() requires that lock.
Take the list lock while moving the queued contexts back to the free
list to avoid racing with other global msg ctx list users.

------------------
From: Yichong Chen <chenyichong@uniontech.com>
commit 2602b79c5b3e2f6fce12e38a670f8e3fda4e46a2 upstream.
ecryptfs_parse_packet_set() receives a pointer into the file header, but
it calculates the remaining packet buffer size from PAGE_SIZE - 8. For
version 1 headers the packet set starts later in the header, so this can
overstate the available buffer.
Pass the actual packet set buffer length from the caller and calculate
per-packet limits from the remaining bytes in that buffer. Recompute the
remaining length after consuming a tag 3 packet before parsing the
following tag 11 packet.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: HanQuan <eilaimemedsnaimel@gmail.com>
commit 5babe9c177c364521e3e682b949c5a8c47f4a441 upstream.
parse_tag_3_packet() set encrypted_key_size from the Tag 3 packet body
without bounding it against ECRYPTFS_MAX_KEY_BYTES (64). When
encrypted_key_size > 64, decrypt_passphrase_encrypted_session_key()
sets decrypted_key_size = encrypted_key_size and performs two
out-of-bounds writes:
1. crypto_skcipher_decrypt() writes encrypted_key_size bytes into
decrypted_key[64] via scatterlist, overflowing into the parent
ecryptfs_auth_tok struct.
2. memcpy(crypt_stat->key, decrypted_key, decrypted_key_size) writes
into crypt_stat->key[64], corrupting root_iv, keysig_list, and
mutexes in ecryptfs_crypt_stat.
Only AES-192 (cipher code 0x08) enables this because it sets
crypt_stat->key_size = 24 independently of encrypted_key_size,
allowing crypto_skcipher_setkey() to succeed while encrypted_key_size
exceeds ECRYPTFS_MAX_KEY_BYTES.
The PKI decryption path (parse_tag_65_packet) already validates
decrypted_key_size <= ECRYPTFS_MAX_KEY_BYTES; the passphrase path
omits this check.
Bound encrypted_key_size against ECRYPTFS_MAX_KEY_BYTES (64) rather
than ECRYPTFS_MAX_ENCRYPTED_KEY_BYTES (512). The 64-byte limit also
protects the 512-byte encrypted_key[] buffer, so the former 512-byte
check is removed as redundant.

From: Yichong Chen <chenyichong@uniontech.com>
commit e97bbe1b2bd82ec2ae37ad2e4965b4d3e78bbf7f upstream.
ecryptfs_parse_tag_70_packet() subtracts fixed metadata fields from the
parsed packet body size to derive the encrypted filename size. A
malformed packet with a body smaller than those fixed fields can underflow
that size calculation.
Reject tag 70 packets before the subtraction unless the body contains the
signature, cipher code, and at least one byte of encrypted filename data.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel <ardb@kernel.org>
commit b2326338dc683e8c1067c0cbf7a47986c4190902 upstream.
Ravi reports that statfs() may be called by unprivileged users on the
efivarfs mount point, which may result in a flood of calls to the
QueryVariableInfo() runtime service. These calls are disproportionately
costly on x86 systems where the variable store is backed by SMM, as each
SMM entry requires a rendez-vous of all the CPUs.
So rate limit the calls to QueryVariableInfo() at twice per second, and
return the most recently obtained value for calls that are elided.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yemu Lu <prcups@krgm.moe>
commit 64d9183203eebe33de6188b70a8c1e91f52885db upstream.
fat_ent_write() may have committed the new link to the primary FAT but
then failed on the mirror copy, leaving the chain pointing to new_dclus
even though the caller will free it. Restore the original value to keep
the chain consistent.

From: Runyu Xiao <runyu.xiao@seu.edu.cn>
commit f8e43fe0f22b7137ce456e6fe3581d3098174f74 upstream.
dsicm_probe() registers the display before initializing ddata->lock.
Once omapdss_register_display() publishes the display, another consumer
can reach a dsicm callback that takes this mutex while it is still
uninitialized.
Initialize the mutex before registering the display so the published
callbacks always see a valid lock.

From: Myeonghun Pak <mhun512@gmail.com>
commit de8db23aa7c337e606fca9faf48b3ba72968597a upstream.
uvesafb_init() registers the v86d connector callback before registering
the platform driver. If platform_driver_register() fails, the function
returns the error directly and leaves the connector callback registered.
The later platform-device failure path already unregisters the callback.
Add the same cleanup before the final return when platform-driver
registration fails.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Czernohous <marek@czernohous.de>
commit 9393f1d656a79693e0c123ff7bc7c5c0f708046d upstream.
nv_suspend() and nv_resume() walk the non-PCI configuration space with
for (i = 0; i <= np->register_size/sizeof(u32); i++)
which runs one iteration too many. saved_config_space is declared as
u32 saved_config_space[NV_PCI_REGSZ_MAX/4];
and NV_PCI_REGSZ_VER3 is equal to NV_PCI_REGSZ_MAX (0x604), so on a VER3
device register_size/sizeof(u32) is exactly the array length and the last
iteration addresses one element past the end.
The element it lands on is np->name_rx[0..3]: saved_config_space[] is
followed immediately by char name_rx[IFNAMSIZ + 3], and char needs no
padding. Nothing observable is corrupted by that, because nv_request_irq()
rewrites name_rx with sprintf() before it is ever passed to request_irq().
The bug is the out-of-bounds access itself, which UBSAN reports and which
CONFIG_UBSAN_TRAP=y turns into a trap that aborts the running kernel code,
plus an MMIO read and, on resume, an MMIO writel() to base + 0x604, one
dword past the range the driver mapped:
np->base = ioremap(addr, np->register_size);
VER1 and VER2 devices stay inside the array, but they too get the stray
read and the stray write one dword past their own window.
Caught by UBSAN on an Apple Macmini3,1 (MCP79) during a deep S3 cycle.
The splat below is trimmed: the build path in the file name, the CPU
and taint lines, the Workqueue line, the "?" hint frames, and the
frames below device_suspend are all cut. The kernel was tainted, with
an out-of-tree nouveau and CPU_OUT_OF_SPEC; forcedeth itself was the
stock module.
UBSAN: array-index-out-of-bounds in drivers/net/ethernet/nvidia/forcedeth.c:6225:25
index 385 is out of range for type 'u32 [385]'
Call Trace:
dump_stack_lvl+0x5d/0x80
ubsan_epilogue+0x5/0x2b
__ubsan_handle_out_of_bounds.cold+0x54/0x59
__this_module+0xe398c/0xe9010 [forcedeth]
pci_pm_suspend+0x80/0x170
dpm_run_callback+0x51/0x160
device_suspend+0x1a2/0x4a0
...
Both loops are hit. UBSAN reports each source location only once per module
load (__ubsan_handle_out_of_bounds() calls suppress_report(), which does
test_and_set_bit(REPORTED_BIT, ...) on the struct source_location), so the
two splats land in the first S3 cycle after the module is loaded and later
cycles are silent even though the access still runs off the end every time.
In that first cycle line 6225 is reported from pci_pm_suspend and line 6240
from pci_pm_resume.
The same off-by-one was fixed in nv_get_regs() by commit ba9aa134287f
("forcedeth: fix buffer overflow") in 2012; these two loops were missed.
The suspend and resume side was reported on LKML in September 2013 by Marc
Weber, with the same analysis and the same one-character fix, but the patch
was attached rather than sent inline and the thread ended there.
Use < instead of <=, which saves and restores exactly register_size bytes.

commit c14a8b15c87b49efc3ef898cec8ac7c30336a080 upstream.
Fix incorrect stratix10_svc_done() usage during FPGA reconfiguration.
Do not call stratix10_svc_done() at the end of write_init() on success, so
the SVC session remains active through write() and write_complete(). Call
stratix10_svc_done() on failure in write_init() and write() so the shared
SVC mailbox is released when reconfiguration aborts, allowing coexistence
with other SVC clients such as soc64-hwmon.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ivaylo Dimitrov <ivo.g.dimitrov.75@gmail.com>
commit e81250ec6b69248b00d38c523dc6a13efaf38aab upstream.
The OMAP SSI driver uses a synthetic HSI controller device allocated via
hsi_alloc_controller(), which does not go through the normal OF/platform
device initialization path.
As a result, the embedded struct device does not have a DMA mask
initialized by default.
After recent DMA API hardening changes, dma_map_sg() and related helpers
now require a valid dma_mask to be present, otherwise the driver may
crash or trigger warnings when attempting DMA mapping operations.
Fix this by explicitly initializing the DMA mask for the SSI controller
device and setting a 32-bit DMA mask, which matches the hardware
capabilities.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anirudh Prasad <icarus@a0rg.com>
commit ced45be0073a8a31b30b4a7f68cd3a15734515de upstream.
query_capability() copies four ACPI buffer objects returned by the
firmware _DSM into fixed-size u8[16] fields in struct
pfru_update_cap_info using memcpy with the firmware-supplied length:
memcpy(&cap_hdr->code_type,
elements[CAP_CODE_TYPE_IDX].buffer.pointer,
elements[CAP_CODE_TYPE_IDX].buffer.length);
The same pattern repeats for drv_type, platform_id, and oem_id.
If the firmware returns buffer.length > 16 for any of these fields,
memcpy writes past the destination array.
struct pfru_update_cap_info is stack-allocated in pfru_ioctl().
Confirmed with KASAN on 7.2-rc6: three stack-out-of-bounds reports
are generated when a DSM returns 64-byte buffers, with writes reaching
44 bytes past the end of cap_hdr's [64, 156) frame window into
adjacent stack redzones.
Introduce a helper pointer to out_obj->package.elements and use it
to validate each buffer length against its destination field size
before copying, returning -EINVAL if the firmware supplies an
oversized buffer.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Krzysztof Wilczyński <kwilczynski@kernel.org>
commit 651fb94aaf245430590216d497fb8b02dd73d5f9 upstream.
pci_legacy_write() in arch/alpha/kernel/pci-sysfs.c passes its arguments to
outb(), outw() and outl() in the wrong order:
outb(port, val);
The Alpha I/O accessors in arch/alpha/include/asm/io.h take the value first
and the port second:
extern void outb(u8 b, unsigned long port);
So the port number is written as data to the I/O address taken from the
user-supplied value, and the intended write to the requested port never
happens.
The arguments have been reversed since the file was added, and the function
returns the access size regardless, so the caller sees success while the
requested port is left untouched.

Pass base + i to irq_set_status_flags() to match the IRQ number
used in irq_set_chip_and_handler(). Previously, IRQ_LEVEL was set
on the wrong (low-numbered) IRQ descriptors rather than the IO7
IRQs at base + i.

------------------
From: Matt Turner <mattst88@gmail.com>
commit 24d68db713d63dfe3660c56b50e887784844baea upstream.
Move irq_set_chip_and_handler() and irq_set_status_flags() calls
outside the io7->irq_lock raw spinlock. These functions take
sparse_irq_lock, which is a mutex, and taking a sleeping lock while
holding a raw spinlock is invalid. The raw spinlock only needs to
protect the hardware CSR accesses.
This fixes the following lockdep splat during boot:

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ethan Nelson-Moore <enelsonmoore@gmail.com>
commit 7e8ee82e69fde9d589272ec5e6f702358903be1f upstream.
The eBPF JIT unconditionally generates ldrh/strh instructions, which do
not function correctly on the Risc PC because its bus is unable to
signal half-word accesses. Work around this issue by disabling the eBPF
JIT when building for ARMv3 (the Risc PC is the only currently
supported machine whose kernel is built for ARMv3).
Comments from Ethan Nelson-Moore:
From LKML: https://lore.kernel.org/all/CAD++jL=0qYGoygUwGEXQL7C_ROnC7kfpRv8RA+H5tNWwYu+pQA@mail.gmail.com/
The commit message has been updated slightly relative to the version on LKML to clarify that the Risc PC is not actually ARMv3.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Niklas Cassel <cassel@kernel.org>
commit 79cce911e623c0baa0fde307ce3a434e084b881a upstream.
ata_scsi_write_same_xlat() translates a SCSI WRITE SAME command with the
UNMAP bit set into an ATA DATA SET MANAGEMENT TRIM command. The TRIM
descriptor is built by ata_format_dsm_trim_descr() into the 2048-byte
ata_scsi_rbuf staging buffer, and the number of bytes copied is compared
against the logical sector size by the caller:
size = ata_format_dsm_trim_descr(scmd, trmax, block, n_block);
if (size != len) /* len == sdp->sector_size */
goto invalid_param_len;
ata_format_dsm_trim_descr() clamps the copy length to ATA_SCSI_RBUF_SIZE
(2048). On a device whose logical sector size exceeds that (e.g. a 4Kn
device, where sector_size == 4096) the function can never return more than
2048, while the caller expects it to return sector_size. The comparison
therefore always fails, so every TRIM is rejected with "Parameter list
length error" and WARN_ON() splats on each attempt. TRIM / discard is
thus completely broken on such devices.
The descriptor was incorrectly sized from the logical sector size. A DSM
TRIM payload is a list of 512-byte pages, each holding up to
ATA_MAX_TRIM_RNUM (64) LBA Range Entries, and is independent of the logical
sector size. The Block Limits VPD page already advertises a single such
page as the maximum WRITE SAME length (65535 * ATA_MAX_TRIM_RNUM logical
blocks), so the block layer never sends a request that needs more than one
page.
Emit exactly one 512-byte page, independent of the logical sector size,
and transfer only that page (COUNT == 1). For a 512-byte-sector device
this is unchanged; devices with larger logical sectors now work instead of
failing every TRIM.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hongyan Xu <getshell@seu.edu.cn>
commit e3e3bf40916c1e810df03958cfa7ba6883cdce79 upstream.
With CONFIG_CHARLCD_BL_FLASH, charlcd_init() schedules bl_work before
charlcd_register() calls misc_register(). If registration fails, the
caller frees the charlcd object while delayed work still contains its
address.
Add charlcd_deinit() to cancel the delayed work and turn the backlight
off. Use it for both registration rollback and normal unregistration.
Fixes: 39f8ea46724e ("auxdisplay: charlcd: Extract character LCD core from misc/panel")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Zwerschke <cito@online.de>
commit 980084de4d9b25193398d89a1c0430ba3501b683 upstream.
Add the vendor/product ID (0x0b05, 0x1bef) to the usb_device_id table for
the Realtek RTL8761CU-based ASUS USB-BT540 adapter. It binds via the
generic Bluetooth class today, so BTUSB_REALTEK is never set and the
rtl8761cu firmware is not loaded, leaving the controller non-functional.
With the entry the driver loads rtl_bt/rtl8761cu_fw.bin (already shipped by
linux-firmware) and the adapter works (tested: A2DP and ASHA).
Similar to commit bc597f0cc44f
("Bluetooth: btusb: Add TP-Link UB600 for Realtek 8761BUV").

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: HyeongJun An <sammiee5311@gmail.com>
commit 4beb198bc59b242404a47c21990bc84165052c8a upstream.
eir_get_service_data() walks the advertising data for a Service Data
field with a matching UUID. On a mismatch it advances:
eir += dlen;
eir_len -= dlen;
eir_get_data() reports dlen as the field's data length, but the field
spans dlen + 2 bytes once its length and type bytes count, and more
when non-Service-Data fields were skipped to reach it. The pointer
lands correctly on the next field. eir_len does not, and the shortfall
compounds across fields until eir_get_data() reads the length and type
bytes of a "field" past the end of the buffer.
For an ISO broadcast sink that buffer is hcon->le_per_adv_data[], filled
from the periodic advertising reports of a remote broadcaster. A PA
payload packed with mismatching Service Data fields walks off the array
into the rest of struct hci_conn. A drifted field that matches the BAA
UUID puts those bytes in iso_pi(sk)->base, where user space reads them
back with getsockopt(BT_ISO_BASE).
Recompute eir_len from the end of the buffer each iteration.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiangshan Yi <yijiangshan@kylinos.cn>
commit d2796ffe38cb4155afe0eab23636295b096c27a5 upstream.
bnx2x_init_firmware() frees bp->init_ops, bp->init_data and
bp->init_ops_offsets in its error path without setting them to NULL.
The cleanup function bnx2x_release_firmware() frees the same three
pointers unconditionally, so if init_firmware fails and
release_firmware is later called (e.g. from __bnx2x_remove or through
the function state machine), all three are freed a second time.
Set each pointer to NULL after kfree() in the error path so that the
subsequent kfree(NULL) in bnx2x_release_firmware() is a safe no-op.
Fixes: 94a78b79cb5f ("bnx2x: Separated FW from the source.")

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jérémy Jean <Jeremy.Jean@oss.cyber.gouv.fr>
commit 11c1e836710dcba03e50454a4eedfdbaf8d3050e upstream.
bloom_map_alloc() has two 32-bit-specific problems when the computed
bitmap reaches the U32_MAX fallback case.
First, BITS_TO_BYTES(U32_MAX) is evaluated with 32-bit arithmetic. The
addition performed by DIV_ROUND_UP wraps, so the map allocates only the
fixed-size bloom filter object while keeping bitset_mask == U32_MAX.
Subsequent updates can then write past the allocated object.
Second, fixing only the allocation size is not sufficient. The bloom hash
is a u32, but set_bit() takes a signed long bit number and x86 test_bit()
eventually feeds the index to variable_test_bit(long, ...). On 32-bit
kernels, hashes in [0x80000000, U32_MAX] therefore become negative bit
offsets. x86 bt/bts with a memory operand interpret those offsets relative
to the supplied base, so a map with bitset_mask == U32_MAX can read or
write before bloom->bitset even after allocating the full 512 MiB bitmap.
Keep the U32_MAX fallback, but split each hash into a word pointer and an
in-word bit number before calling test_bit() or set_bit(). The bitops
argument is then always in [0, BITS_PER_LONG - 1], while BIT_WORD(h) still
selects the intended word in the full bitmap.
Compute the bitset size from (u64)bitset_mask + 1 before passing the final
size to bpf_map_area_alloc(). This fixes the original under-allocation and
keeps the allocated storage consistent with the addressable bitset.
Exploitation note: local privilege escalation is possible on a 32-bit x86
kernel using the under-allocation bug from a binary with CAP_BPF.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: liyouhong <liyouhong@kylinos.cn>
commit 39c5aa3bd8ec3912d2cd0b3fe092642b0d2b0713 upstream.
metadata_take_snap() bumps the live superblock refcount and then
dm_tm_shadow_block() allocates a new block for the metadata snapshot.
If the subsequent dm_sm_inc_block() of writeset_tree_root or
era_array_root fails, the function only unlocks the clone and
returns. The newly allocated shadow block is never returned to the
metadata space map, so each failed take-snap permanently leaks one
metadata block.
Free the clone with dm_sm_dec_block() on those error paths, matching
the final step of metadata_drop_snap().

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bryam Vargas <hexlabsecurity@proton.me>
commit 4538a287bdf5d0f9a379c678e5262b9f5783f547 upstream.
array_block_check() can only compare the header against itself, so a block
with value_size 4 and max_entries 1018 is internally consistent and passes.
dm-cache keeps two arrays -- mappings at 8 bytes and hints at 4 -- and the
roots for both live in the superblock. Point the mappings root at a hint
block and __load_mappings() walks it through an info whose value size is 8,
so element_at() strides 8 bytes over 4-byte entries and reaches offset 8160
of a 4096-byte block.
get_ablock() and __shadow_ablock() are the two places that hold the block
and the caller at once. Reject there when the two value sizes disagree.
Arrays only ever read their own blocks, so this fires on crafted metadata
only.

6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hui Su <sh_def@163.com>
commit 3bff8f8e95fdc6ad19c8a1a8f87029094747e4bf upstream.
rate_limit_us is an unsigned int, while NSEC_PER_USEC is defined as
1000L. On 32-bit systems, the multiplication is therefore performed
using 32-bit unsigned arithmetic before the result is assigned to
freq_update_delay_ns.
For example, writing 4294968 to rate_limit_us wraps the delay from
4294968000 ns to 704 ns. This makes schedutil update far more often
than configured.
Add sugov_update_rate_limit_us() to widen rate_limit_us to s64 before
converting it to nanoseconds. Use the helper when updating the tunable
through sysfs and when starting the governor, so both paths perform the
conversion without overflow.
