Sheng Yong reported [1] that Android APEX images didn't work with commit
072a7c7cdb ("erofs: don't bother with s_stack_depth increasing for
now") because "EROFS-formatted APEX file images can be stored within an
EROFS-formatted Android system partition."
In response, I sent a quick fat-fingered [PATCH v3] to address the
report. Unfortunately, the updated condition was incorrect:
if (erofs_is_fileio_mode(sbi)) {
- sb->s_stack_depth =
- file_inode(sbi->dif0.file)->i_sb->s_stack_depth + 1;
- if (sb->s_stack_depth > FILESYSTEM_MAX_STACK_DEPTH) {
- erofs_err(sb, "maximum fs stacking depth exceeded");
+ inode = file_inode(sbi->dif0.file);
+ if ((inode->i_sb->s_op == &erofs_sops && !sb->s_bdev) ||
+ inode->i_sb->s_stack_depth) {
The condition `!sb->s_bdev` is always true for all file-backed EROFS
mounts, making the check effectively a no-op.
The real fix tested and confirmed by Sheng Yong [2] at that time was
[PATCH v3 RESEND], which correctly ensures the following EROFS^2 setup
works:
EROFS (on a block device) + EROFS (file-backed mount)
But sadly I screwed it up again by upstreaming the outdated [PATCH v3].
This patch applies the same logic as the delta between the upstream
[PATCH v3] and the real fix [PATCH v3 RESEND].

Pull erofs fix from Gao Xiang:
- Don't increase s_stack_depth which caused regressions in some
composefs mount setups (EROFS + ovl^2)
Instead just allow one extra unaccounted fs stacking level for
straightforward cases.
* tag 'erofs-for-6.19-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs:
erofs: don't bother with s_stack_depth increasing for now
Previously, commit d53cd891f0 ("erofs: limit the level of fs stacking
for file-backed mounts") bumped `s_stack_depth` by one to avoid kernel
stack overflow when stacking an unlimited number of EROFS on top of
each other.
This fix breaks composefs mounts, which need EROFS+ovl^2 sometimes
(and such setups are already used in production for quite a long time).
One way to fix this regression is to bump FILESYSTEM_MAX_STACK_DEPTH
from 2 to 3, but proving that this is safe in general is a high bar.
After a long discussion on GitHub issues [1] about possible solutions,
one conclusion is that there is no need to support nesting file-backed
EROFS mounts on stacked filesystems, because there is always the option
to use loopback devices as a fallback.
As a quick fix for the composefs regression for this cycle, instead of
bumping `s_stack_depth` for file backed EROFS mounts, we disallow
nesting file-backed EROFS over EROFS and over filesystems with
`s_stack_depth` > 0.
This works for all known file-backed mount use cases (composefs,
containerd, and Android APEX for some Android vendors), and the fix is
self-contained.
Essentially, we are allowing one extra unaccounted fs stacking level of
EROFS below stacking filesystems, but EROFS can only be used in the read
path (i.e. overlayfs lower layers), which typically has much lower stack
usage than the write path.
We can consider increasing FILESYSTEM_MAX_STACK_DEPTH later, after more
stack usage analysis or using alternative approaches, such as splitting
the `s_stack_depth` limitation according to different combinations of
stacking.

Pull vfs fixes from Christian Brauner:
- Remove incorrect __user annotation from struct xattr_args::value
- Documentation fix: Add missing kernel-doc description for the @isnew
parameter in ilookup5_nowait() to silence Sphinx warnings
- Documentation fix: Fix kernel-doc comment for __start_dirop() - the
function name in the comment was wrong and the @state parameter was
undocumented
- Replace dynamic folio_batch allocation with stack allocation in
iomap_zero_range(). The dynamic allocation was problematic for
ext4-on-iomap work (didn't handle allocation failure properly) and
triggered lockdep complaints. Uses a flag instead to control batch
usage
- Re-add #ifdef guards around PIDFD_GET_<ns-type>_NAMESPACE ioctls.
When a namespace type is disabled, ns->ops is NULL, causes crashes
during inode eviction when closing the fd. The ifdefs were removed in
a recent simplification but are still needed
- Fixe a race where a folio could be unlocked before the trailing zeros
(for EOF within the page) were written
- Split out a dedicated lease_dispose_list() helper since lease code
paths always know they're disposing of leases. Removes unnecessary
runtime flag checks and prepares for upcoming lease_manager
enhancements
- Fix userland delegation requests succeeding despite conflicting
opens. Previously, FL_LAYOUT and FL_DELEG leases bypassed conflict
checks (a hack for nfsd). Adds new ->lm_open_conflict() lease_manager
operation so userland delegations get proper conflict checking while
nfsd can continue its own conflict handling
- Fix LOOKUP_CACHED path lookups incorrectly falling through to the
slow path. After legitimize_links() calls were conditionally elided,
the routine would always fail with LOOKUP_CACHED regardless of
whether there were any links. Now the flag is checked at the two
callsites before calling legitimize_links()
- Fix bug in media fd allocation in media_request_alloc()
- Fix mismatched API calls in ecryptfs_mknod(): was calling
end_removing() instead of end_creating() after
ecryptfs_start_creating_dentry()

The __alloc_percpu() fails when the number of IDs are greater than 959
because size parameter of __alloc_percpu() must be less than 32768 (aka
PCPU_MIN_UNIT_SIZE). This failure is observed with KVMTOOL when AIA is
trap-n-emulated by in-kernel KVM because in this case KVM guest has 2047
interrupt IDs.
To address this issue, don't embed vector array in struct imsic_local_priv
until __alloc_percpu() support size parameter greater than 32768.
This reverts commit 79eaabc61d ("irqchip/riscv-imsic: Embed the vector
array in lpriv").

A race condition exists between the async partition scan work and device
teardown that can lead to a use-after-free of ub->ub_disk:
1. ublk_ctrl_start_dev() schedules partition_scan_work after add_disk()
2. ublk_stop_dev() calls ublk_stop_dev_unlocked() which does:
- del_gendisk(ub->ub_disk)
- ublk_detach_disk() sets ub->ub_disk = NULL
- put_disk() which may free the disk
3. The worker ublk_partition_scan_work() then dereferences ub->ub_disk
leading to UAF
Fix this by using ublk_get_disk()/ublk_put_disk() in the worker to hold
a reference to the disk during the partition scan. The spinlock in
ublk_get_disk() synchronizes with ublk_detach_disk() ensuring the worker
either gets a valid reference or sees NULL and exits early.
Also change flush_work() to cancel_work_sync() to avoid running the
partition scan work unnecessarily when the disk is already detached.

sched_mm_cid_after_execve() is called in bprm_execve()'s cleanup path even
when exec_binprm() fails. For the init task's first execve(), this causes a
problem:
1. current->mm is NULL (kernel threads don't have an mm)
2. sched_mm_cid_before_execve() exits early because mm is NULL
3. exec_binprm() fails (e.g., ENOENT for missing script interpreter)
4. sched_mm_cid_after_execve() is called with mm still NULL
5. sched_mm_cid_fork() is called unconditionally, triggering WARN_ON
This is easily reproduced by booting with an init that is a shell script
(#!/bin/sh) where the interpreter doesn't exist in the initramfs.
Fix this by checking if t->mm is NULL before calling sched_mm_cid_fork(),
matching the behavior of sched_mm_cid_before_execve() which already
handles this case via sched_mm_cid_exit()'s early return.

TCR2_ELx.E0POE is set during smp_init().
However, this bit is not reprogrammed when the CPU enters suspension and
later resumes via cpu_resume(), as __cpu_setup() does not re-enable E0POE
and there is no save/restore logic for the TCR2_ELx system register.
As a result, the E0POE feature no longer works after cpu_resume().
To address this, save and restore TCR2_EL1 in the cpu_suspend()/cpu_resume()
path, rather than adding related logic to __cpu_setup(), taking into account
possible future extensions of the TCR2_ELx feature.

After scanning the devicetree, we remove all entries that have only one
reference, while creating GPIO shared proxies for the remaining, shared
entries. However: for the reset-gpio corner-case, we will have two
references for a "reset-gpios" pin that's not really shared. In this
case one will come from the actual consumer fwnode and the other from
the potential auxiliary reset-gpio device. This causes the GPIO core to
create unnecessary GPIO shared proxy devices for pins that are not
really shared.
Add a function that can detect this situation and remove entries that
have exactly two references but one of them is a reset-gpio.

# vmalloc_helpers_tags: try faulted
not ok 67 vmalloc_helpers_tags
Commit a06494adb7 ("arm64: mm: use untagged address to calculate page index")
fixed a KASAN warning in the BPF subsystem by adding kasan_reset_tag() to
the index calculation. In the execmem flow:
bpf_prog_pack_alloc()
-> bpf_jit_alloc_exec()
-> execmem_alloc()
The returned address from execmem_vmalloc/execmem_cache_alloc is passed
through kasan_reset_tag(), so start has no tag while area->addr still
retains the original tag. The fix correctly handled this case by resetting
the tag on area->addr:
(start - (unsigned long)kasan_reset_tag(area->addr)) >> PAGE_SHIFT
However, in normal vmalloc paths, both start and area->addr have matching
tags(or no tags). Resetting only area->addr causes a mismatch when
subtracting a tagged address from an untagged one, resulting in an
incorrect index.
Fix this by resetting tags on both addresses in the index calculation.
This ensures correct results regardless of the tag state of either address.
Tested with KASAN KUnit tests under CONFIG_KASAN_GENERIC,
CONFIG_KASAN_SW_TAGS, and CONFIG_KASAN_HW_TAGS - all pass. Also verified
the original BPF KASAN warning from [1] is still fixed.

On my development machine the generic, memcpy()-only implementation of
polyval_preparekey() is too fast for the IRQ workers to actually fire.
The test fails.
Increase the iterations to make the test more robust.
The test will run for a maximum of one second in any case.
[EB: This failure was already fixed by commit c31f4aa8fe ("kunit:
Enforce task execution in {soft,hard}irq contexts"). I'm still applying
this patch too, since the iteration count in this test made its running

Pull tracing fixes from Steven Rostedt:
- Remove useless assignment of soft_mode variable
The function __ftrace_event_enable_disable() sets "soft_mode" in one
of the branch paths but doesn't use it after that. Remove the setting
of that variable.
- Add a cond_resched() in ring_buffer_resize()
The resize function that allocates all the pages for the ring buffer
was causing a soft lockup on PREEMPT_NONE configs when allocating
large buffers on machines with many CPUs. Hopefully this is the last
cond_resched() needed to be added as PREEMPT_LAZY becomes the norm in
the future.
- Make ftrace_graph_ent depth field signed
The "depth" field of struct ftrace_graph_ent was converted from "int"
to "unsigned long" for alignment reasons to work with being embedded
in other structures. The conversion from a signed to unsigned caused
integrity checks to always pass as they were comparing "depth" to
less than zero. Make the field signed long.
- Add recursion protection to stack trace events
A infinite recursion was triggered by a stack trace event calling RCU
which internally called rcu_read_unlock_special(), which triggered an
event that was also doing stacktraces which cause it to trigger the
same RCU lock that called rcu_read_unlock_special() again.
Update the trace_test_and_set_recursion() to add a set of context
checks for events to use, and have the stack trace event use that for
recursion protection.
- Make the variable ftrace_dump_on_oops static
The cleanup of sysctl that moved all the updates to the files that
use them moved the reference of ftrace_dump_on_oops to where it is
used. It is no longer used outside of the trace.c file. Make it
