commit 4636e859eb upstream.
User Perspective:
When a user sets the phase value, the ad9832_write_phase() is called.
The phase register has a 12-bit resolution, so the valid range is 0 to
4095. If the phase offset value of 4096 is input, it effectively exactly
equals 0 in the lower 12 bits, meaning no offset.
Reasons for the Change:
1) Original Condition (phase > BIT(AD9832_PHASE_BITS)):
This condition allows a phase value equal to 2^12, which is 4096.
However, this value exceeds the valid 12-bit range, as the maximum valid
phase value should be 4095.
2) Modified Condition (phase >= BIT(AD9832_PHASE_BITS)):
Ensures that the phase value is within the valid range, preventing
invalid datafrom being written.
Impact on Subsequent Logic: st->data = cpu_to_be16(addr | phase):
If the phase value is 2^12, i.e., 4096 (0001 0000 0000 0000), and addr
is AD9832_REG_PHASE0 (1100 0000 0000 0000), then addr | phase results in
1101 0000 0000 0000, occupying DB12. According to the section of WRITING
TO A PHASE REGISTER in the datasheet, the MSB 12 PHASE0 bits should be
DB11. The original condition leads to incorrect DB12 usage, which
contradicts the datasheet and could pose potential issues for future
updates if DB12 is used in such related cases.

commit 7ed4e4a659 upstream.
The TongFang GM5HG0A is a TongFang barebone design which is sold under
various brand names.
The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.
At least on the SKIKK Vanaheim variant the DMI product- and board-name
strings have been replaced by the OEM with "Vanaheim" so checking that
board-name contains "GM5HG0A" as is usually done for TongFang barebones
quirks does not work.
The DMI OEM strings do contain "GM5HG0A". I have looked at the dmidecode
for a few other TongFang devices and the TongFang code-name string being
in the OEM strings seems to be something which is consistently true.
Add a quirk checking one of the DMI_OEM_STRING(s) is "GM5HG0A" in the hope
that this will work for other OEM versions of the "GM5HG0A" too.

Since commit 3feb70a617 ("gpio: loongson: add more gpio chip

However, according to the firmware development specification, the
Loongson-2K2000 ACPI GPIO register offsets in the driver do not match
the register base addresses in the firmware, resulting in the registers
not being accessed properly.
Now, we fix it to ensure the GPIO function works properly.

commit 344bac8f0d upstream.
Move mnt->mnt_node into the union with mnt->mnt_rcu and mnt->mnt_llist
instead of keeping it with mnt->mnt_list. This allows us to use
RB_CLEAR_NODE(&mnt->mnt_node) in umount_tree() as well as
list_empty(&mnt->mnt_node). That in turn allows us to remove MNT_ONRB.
This also fixes the bug reported in [1] where seemingly MNT_ONRB wasn't
set in @mnt->mnt_flags even though the mount was present in the mount
rbtree of the mount namespace.
The root cause is the following race. When a btrfs subvolume is mounted
a temporary mount is created:
btrfs_get_tree_subvol()
{
mnt = fc_mount()
// Register the newly allocated mount with sb->mounts:
lock_mount_hash();
list_add_tail(&mnt->mnt_instance, &mnt->mnt.mnt_sb->s_mounts);
unlock_mount_hash();
}
and registered on sb->s_mounts. Later it is added to an anonymous mount
namespace via mount_subvol():
-> mount_subvol()
-> mount_subtree()
-> alloc_mnt_ns()
mnt_add_to_ns()
vfs_path_lookup()
put_mnt_ns()
The mnt_add_to_ns() call raises MNT_ONRB in @mnt->mnt_flags. If someone
concurrently does a ro remount:
reconfigure_super()
-> sb_prepare_remount_readonly()
{
list_for_each_entry(mnt, &sb->s_mounts, mnt_instance) {
}
all mounts registered in sb->s_mounts are visited and first
MNT_WRITE_HOLD is raised, then MNT_READONLY is raised, and finally
MNT_WRITE_HOLD is removed again.
The flag modification for MNT_WRITE_HOLD/MNT_READONLY and MNT_ONRB race
so MNT_ONRB might be lost.

commit 20b1aa9123 upstream.
In some cases, when password2 becomes the working password, the
client swaps the two password fields in the root session struct, but
not in the smb3_fs_context struct in cifs_sb. DFS automounts inherit
fs context from their parent mounts. Therefore, they might end up
getting the passwords in the stale order.
The automount should succeed, because the mount function will end up
retrying with the actual password anyway. But to reduce these
unnecessary session setup retries for automounts, we can sync the
parent context's passwords with the root session's passwords before
duplicating it to the child's fs context.

[ Upstream commit a2a3374c47 ]
With the consolidation of put_prev_task/set_next_task(), see
commit 436f3eed5c ("sched: Combine the last put_prev_task() and the
first set_next_task()"), we are now skipping the transition between
these two functions when the previous and the next tasks are the same.
As a result, the scx idle state of a CPU is updated only when
transitioning to or from the idle thread. While this is generally
correct, it can lead to uneven and inefficient core utilization in
certain scenarios [1].
A typical scenario involves proactive wake-ups: scx_bpf_pick_idle_cpu()
selects and marks an idle CPU as busy, followed by a wake-up via
scx_bpf_kick_cpu(), without dispatching any tasks. In this case, the CPU
continues running the idle thread, returns to idle, but remains marked
as busy, preventing it from being selected again as an idle CPU (until a
task eventually runs on it and releases the CPU).
For example, running a workload that uses 20% of each CPU, combined with
an scx scheduler using proactive wake-ups, results in the following core
utilization:
CPU 0: 25.7%
CPU 1: 29.3%
CPU 2: 26.5%
CPU 3: 25.5%
CPU 4: 0.0%
CPU 5: 25.5%
CPU 6: 0.0%
CPU 7: 10.5%
To address this, refresh the idle state also in pick_task_idle(), during
idle-to-idle transitions, but only trigger ops.update_idle() on actual
state changes to prevent unnecessary updates to the scx scheduler and
maintain balanced state transitions.
With this change in place, the core utilization in the previous example
becomes the following:
CPU 0: 18.8%
CPU 1: 19.4%
CPU 2: 18.0%
CPU 3: 18.7%
CPU 4: 19.3%
CPU 5: 18.9%
CPU 6: 18.7%
CPU 7: 19.3%

This warning is caused by 'kernfs_break_active_protection' when it is
writing to cpuset.cpus, and the cgroup is removed concurrently.
The commit 3a5a6d0c2b ("cpuset: don't nest cgroup_mutex inside
get_online_cpus()") made cpuset_hotplug_workfn asynchronous, This change
involves calling flush_work(), which can create a multiple processes
circular locking dependency that involve cgroup_mutex, potentially leading
to a deadlock. To avoid deadlock. the commit 76bb5ab8f6 ("cpuset: break
kernfs active protection in cpuset_write_resmask()") added
'kernfs_break_active_protection' in the cpuset_write_resmask. This could
lead to this warning.
After the commit 2125c0034c ("cgroup/cpuset: Make cpuset hotplug
processing synchronous"), the cpuset_write_resmask no longer needs to
wait the hotplug to finish, which means that concurrent hotplug and cpuset
operations are no longer possible. Therefore, the deadlock doesn't exist
anymore and it does not have to 'break active protection' now. To fix this
warning, just remove kernfs_break_active_protection operation in the
'cpuset_write_resmask'.

scx_ops_bypass() iterates all CPUs to re-enqueue all the scx tasks.
For each CPU, it acquires a lock using rq_lock() regardless of whether
a CPU is offline or the CPU is currently running a task in a higher
scheduler class (e.g., deadline). The rq_lock() is supposed to be used
for online CPUs, and the use of rq_lock() may trigger an unnecessary
warning in rq_pin_lock(). Therefore, replace rq_lock() to
raw_spin_rq_lock() in scx_ops_bypass().
Without this change, we observe the following warning:
===== START =====

[ Upstream commit 9b496a8bbe ]
Isolated CPUs are not allowed to be used in a non-isolated partition.
The only exception is the top cpuset which is allowed to contain boot
time isolated CPUs.
Commit ccac8e8de9 ("cgroup/cpuset: Fix remote root partition creation
problem") introduces a simplified scheme of including only partition
roots in sched domain generation. However, it does not properly account
for this exception case. This can result in leakage of isolated CPUs
into a sched domain.
Fix it by making sure that isolated CPUs are excluded from the top
cpuset before generating sched domains.
Also update the way the boot time isolated CPUs are handled in
test_cpuset_prs.sh to make sure that those isolated CPUs are really
isolated instead of just skipping them in the tests.

commit 7f5611cbc4 upstream.
As mentioned in a previous commit of this series, using the 'net'
structure via 'current' is not recommended for different reasons:
- Inconsistency: getting info from the reader's/writer's netns vs only
from the opener's netns.
- current->nsproxy can be NULL in some cases, resulting in an 'Oops'
(null-ptr-deref), e.g. when the current task is exiting, as spotted by
syzbot [1] using acct(2).
The per-netns structure can be obtained from the table->data using
container_of(), then the 'net' one can be retrieved from the listen
socket (if available).

commit 6df90c02ba upstream.
This patch fixes an issue that was fixed in the commit
df7b59ba92 ("dm verity: fix FEC for RS roots unaligned to block size")
but later broken again in the commit
8ca7cab82b ("dm verity fec: fix misaligned RS roots IO")
If the Reed-Solomon roots setting spans multiple blocks, the code does not
use proper parity bytes and randomly fails to repair even trivial errors.
This bug cannot happen if the sector size is multiple of RS roots
setting (Android case with roots 2).
The previous solution was to find a dm-bufio block size that is multiple
of the device sector size and roots size. Unfortunately, the optimization
in commit 8ca7cab82b ("dm verity fec: fix misaligned RS roots IO")
is incorrect and uses data block size for some roots (for example, it uses
4096 block size for roots = 20).
This patch uses a different approach:
- It always uses a configured data block size for dm-bufio to avoid
possible misaligned IOs.
- and it caches the processed parity bytes, so it can join it
if it spans two blocks.
As the RS calculation is called only if an error is detected and
the process is computationally intensive, copying a few more bytes
should not introduce performance issues.
The issue was reported to cryptsetup with trivial reproducer
https://gitlab.com/cryptsetup/cryptsetup/-/issues/923
Reproducer (with roots=20):
# create verity device with RS FEC
dd if=/dev/urandom of=data.img bs=4096 count=8 status=none
veritysetup format data.img hash.img --fec-device=fec.img --fec-roots=20 | \
awk '/^Root hash/{ print $3 }' >roothash
# create an erasure that should always be repairable with this roots setting
dd if=/dev/zero of=data.img conv=notrunc bs=1 count=4 seek=4 status=none
# try to read it through dm-verity
veritysetup open data.img test hash.img --fec-device=fec.img --fec-roots=20 $(cat roothash)
dd if=/dev/mapper/test of=/dev/null bs=4096 status=noxfer
Even now the log says it cannot repair it:
: verity-fec: 7:1: FEC 0: failed to correct: -74
: device-mapper: verity: 7:1: data block 0 is corrupted
...
With this fix, errors are properly repaired.
: verity-fec: 7:1: FEC 0: corrected 4 errors

commit 974e3fe0ac upstream.
Encoding file handles is usually performed by a filesystem >encode_fh()
method that may fail for various reasons.
The legacy users of exportfs_encode_fh(), namely, nfsd and
name_to_handle_at(2) syscall are ready to cope with the possibility
of failure to encode a file handle.
There are a few other users of exportfs_encode_{fh,fid}() that
currently have a WARN_ON() assertion when ->encode_fh() fails.
Relax those assertions because they are wrong.
The second linked bug report states commit 16aac5ad1f ("ovl: support
encoding non-decodable file handles") in v6.6 as the regressing commit,
but this is not accurate.
The aforementioned commit only increases the chances of the assertion
and allows triggering the assertion with the reproducer using overlayfs,
inotify and drop_caches.
Triggering this assertion was always possible with other filesystems and
other reasons of ->encode_fh() failures and more particularly, it was
also possible with the exact same reproducer using overlayfs that is
mounted with options index=on,nfs_export=on also on kernels < v6.6.
Therefore, I am not listing the aforementioned commit as a Fixes commit.
Backport hint: this patch will have a trivial conflict applying to
v6.6.y, and other trivial conflicts applying to stable kernels < v6.6.

commit 7bac656875 upstream.
PHY might already be powered on during ufs_qcom_power_up_sequence() in a
couple of cases:
1. During UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH quirk
2. Resuming from spm_lvl = 5 suspend
In those cases, it is necessary to call phy_power_off() and phy_exit() in
ufs_qcom_power_up_sequence() function to power off the PHY before calling
phy_init() and phy_power_on().
Case (1) is doing it via ufs_qcom_reinit_notify() callback, but case (2) is
not handled. So to satisfy both cases, call phy_power_off() and phy_exit()
if the phy_count is non-zero. And with this change, the reinit_notify()
callback is no longer needed.
This fixes the below UFS resume failure with spm_lvl = 5:

commit 80f130bfad upstream.
The documentation in rculist.h explains the absence of list_empty_rcu()
and cautions programmers against relying on a list_empty() ->
list_first() sequence in RCU safe code. This is because each of these
functions performs its own READ_ONCE() of the list head. This can lead
to a situation where the list_empty() sees a valid list entry, but the
subsequent list_first() sees a different view of list head state after a
modification.
In the case of dm-thin, this author had a production box crash from a GP
fault in the process_deferred_bios path. This function saw a valid list
head in get_first_thin() but when it subsequently dereferenced that and
turned it into a thin_c, it got the inside of the struct pool, since the
list was now empty and referring to itself. The kernel on which this
occurred printed both a warning about a refcount_t being saturated, and
a UBSAN error for an out-of-bounds cpuid access in the queued spinlock,
prior to the fault itself. When the resulting kdump was examined, it
was possible to see another thread patiently waiting in thin_dtr's
synchronize_rcu.
The thin_dtr call managed to pull the thin_c out of the active thins
list (and have it be the last entry in the active_thins list) at just
the wrong moment which lead to this crash.
Fortunately, the fix here is straight forward. Switch get_first_thin()
function to use list_first_or_null_rcu() which performs just a single
READ_ONCE() and returns NULL if the list is already empty.
This was run against the devicemapper test suite's thin-provisioning
