7b5ab04f03 timekeeping: Fix resource leak in tk_aux_sysfs_init() error paths
tk_aux_sysfs_init() returns immediately on error during the auxiliary clock
initialization loop without cleaning up previously allocated kobjects and
sysfs groups.

If kobject_create_and_add() or sysfs_create_group() fails during loop
iteration, the parent kobjects (tko and auxo) and any previously created
child kobjects are leaked.

Fix this by adding proper error handling with goto labels to ensure all
allocated resources are cleaned up on failure. kobject_put() on the
parent kobjects will handle cleanup of their children.

002541ef65 vsock: Ignore signal/timeout on connect() if already established
During connect(), acting on a signal/timeout by disconnecting an already
established socket leads to several issues:

1. connect() invoking vsock_transport_cancel_pkt() ->
   virtio_transport_purge_skbs() may race with sendmsg() invoking
   virtio_transport_get_credit(). This results in a permanently elevated
   `vvs->bytes_unsent`. Which, in turn, confuses the SOCK_LINGER handling.

2. connect() resetting a connected socket's state may race with socket
   being placed in a sockmap. A disconnected socket remaining in a sockmap
   breaks sockmap's assumptions. And gives rise to WARNs.

3. connect() transitioning SS_CONNECTED -> SS_UNCONNECTED allows for a
   transport change/drop after TCP_ESTABLISHED. Which poses a problem for
   any simultaneous sendmsg() or connect() and may result in a
   use-after-free/null-ptr-deref.

Do not disconnect socket on signal/timeout. Keep the logic for unconnected
sockets: they don't linger, can't be placed in a sockmap, are rejected by
sendmsg().

91842ed844 ata: libata-core: Set capacity to zero for a security locked drive
For Security locked drives (drives that have Security enabled, and have

  sd 4:0:0:0: [sda] tag#7 Add. Sense: No additional sense information

during boot, because most commands except for IDENTIFY will be aborted by
a Security locked drive.

For a Security locked drive, set capacity to zero, so that no automatic
partition scanning will happen.

If the user later unlocks the drive using e.g. hdparm, the close() by the
user space application should trigger a revalidation of the drive.

b118906833 ata: libata-scsi: Fix system suspend for a security locked drive
Commit cf3fc03762 ("ata: libata-scsi: Fix ata_to_sense_error() status
handling") fixed ata_to_sense_error() to properly generate sense key
ABORTED COMMAND (without any additional sense code), instead of the
previous bogus sense key ILLEGAL REQUEST with the additional sense code
UNALIGNED WRITE COMMAND, for a failed command.

However, this broke suspend for Security locked drives (drives that have
Security enabled, and have not been Security unlocked by boot firmware).

The reason for this is that the SCSI disk driver, for the Synchronize
Cache command only, treats any sense data with sense key ILLEGAL REQUEST
as a successful command (regardless of ASC / ASCQ).

After commit cf3fc03762 ("ata: libata-scsi: Fix ata_to_sense_error()
status handling") the code that treats any sense data with sense key
ILLEGAL REQUEST as a successful command is no longer applicable, so the
command fails, which causes the system suspend to be aborted:

  sd 1:0:0:0: PM: dpm_run_callback(): scsi_bus_suspend returns -5
  sd 1:0:0:0: PM: failed to suspend async: error -5
  PM: Some devices failed to suspend, or early wake event detected

To make suspend work once again, for a Security locked device only,
return sense data LOGICAL UNIT ACCESS NOT AUTHORIZED, the actual sense
data which a real SCSI device would have returned if locked.
The SCSI disk driver treats this sense data as a successful command.

d70b592551 l2tp: reset skb control buffer on xmit
The L2TP stack did not reset the skb control buffer before sending the
encapsulated package.

In a setup with an ath10k radio and batman-adv over an L2TP tunnel
massive fragmentations happen sporadically if the L2TP tunnel is
established over IPv4.

L2TP might reset some of the fields in the IP control buffer, but L2TP
assumes the type of the control buffer to be of an IPv4 packet.

In case the L2TP interface is used as a batadv hardif or the packet is
an IPv6 packet, this assumption breaks.

Clear the entire control buffer to avoid such mishaps altogether.

3ceb6ac211 net: dsa: microchip: lan937x: Fix RGMII delay tuning
Correct RGMII delay application logic in lan937x_set_tune_adj().

The function was missing `data16 &= ~PORT_TUNE_ADJ` before setting the
new delay value. This caused the new value to be bitwise-OR'd with the
existing PORT_TUNE_ADJ field instead of replacing it.

For example, when setting the RGMII 2 TX delay on port 4, the
intended TUNE_ADJUST value of 0 (RGMII_2_TX_DELAY_2NS) was
incorrectly OR'd with the default 0x1B (from register value 0xDA3),
leaving the delay at the wrong setting.

This patch adds the missing mask to clear the field, ensuring the
correct delay value is written. Physical measurements on the RGMII TX
lines confirm the fix, showing the delay changing from ~1ns (before
change) to ~2ns.

While testing on i.MX 8MP showed this was within the platform's timing
tolerance, it did not match the intended hardware-characterized value.

 ==================================================================

On further analysis, I realized that the second parameter to min() is
not correct.  xfs_ifork::if_bytes is the size of the xfs_ifork::if_data
buffer.  if_bytes can be smaller than the data fork size because:

(a) the forkoff code tries to keep the data area as large as possible
(b) for symbolic links, if_bytes is the ondisk file size + 1
(c) forkoff is always a multiple of 8.

Case in point: for a single-byte symlink target, forkoff will be
8 but the buffer will only be 2 bytes long.

In other words, the logic here is wrong and we walk off the end of the
incore buffer.  Fix that.

f1f96511b1 perf: Fix 0 count issue of cpu-clock
Currently cpu-clock event always returns 0 count, e.g.,

perf stat -e cpu-clock -- sleep 1

 Performance counter stats for 'sleep 1':
                 0      cpu-clock                        #    0.000 CPUs utilized
       1.002308394 seconds time elapsed

The root cause is the commit 'bc4394e5e79c ("perf: Fix the throttle
 error of some clock events")' adds PERF_EF_UPDATE flag check before
calling cpu_clock_event_update() to update the count, however the
PERF_EF_UPDATE flag is never set when the cpu-clock event is stopped in
counting mode (pmu->dev() -> cpu_clock_event_del() ->
cpu_clock_event_stop()). This leads to the cpu-clock event count is
never updated.

To fix this issue, force to set PERF_EF_UPDATE flag for cpu-clock event
just like what task-clock does.

7e4d9120cf cifs: fix memory leak in smb3_fs_context_parse_param error path
Add proper cleanup of ctx->source and fc->source to the
cifs_parse_mount_err error handler. This ensures that memory allocated
for the source strings is correctly freed on all error paths, matching
the cleanup already performed in the success path by
smb3_cleanup_fs_context_contents().
Pointers are also set to NULL after freeing to prevent potential
double-free issues.

This change fixes a memory leak originally detected by syzbot. The
leak occurred when processing Opt_source mount options if an error
happened after ctx->source and fc->source were successfully
allocated but before the function completed.

The specific leak sequence was:
1. ctx->source = smb3_fs_context_fullpath(ctx, '/') allocates memory
2. fc->source = kstrdup(ctx->source, GFP_KERNEL) allocates more memory
3. A subsequent error jumps to cifs_parse_mount_err
4. The old error handler freed passwords but not the source strings,
causing the memory to leak.

This issue was not addressed by commit e8c73eb7db ("cifs: client:
fix memory leak in smb3_fs_context_parse_param"), which only fixed
leaks from repeated fsconfig() calls but not this error path.

Patch updated with minor change suggested by kernel test robot

kref_put_lock() to avoid recursive locking when dropping references.

While the existing code works if the refcount >= 2 invariant holds,

677e6123e3 LoongArch: BPF: Disable trampoline for kernel module function trace
The current LoongArch BPF trampoline implementation is incompatible
with tracing functions in kernel modules. This causes several severe
and user-visible problems:

* The `bpf_selftests/module_attach` test fails consistently.
* Kernel lockup when a BPF program is attached to a module function [1].
* Critical kernel modules like WireGuard experience traffic disruption
  when their functions are traced with fentry [2].

Given the severity and the potential for other unknown side-effects, it
is safest to disable the feature entirely for now. This patch prevents
the BPF subsystem from allowing trampoline attachments to kernel module
functions on LoongArch.

This is a temporary mitigation until the core issues in the trampoline
code for kernel module handling can be identified and fixed.

0e4ec14dc1 selftests: mptcp: join: userspace: longer timeout
In rare cases, when the test environment is very slow, some userspace
tests can fail because some expected events have not been seen.

Because the tests are expecting a long on-going connection, and they are
not waiting for the end of the transfer, it is fine to have a longer
timeout, and even go over the default one. This connection will be
killed at the end, after the verifications: increasing the timeout
doesn't change anything, apart from avoiding it to end before the end of
the verifications.

To play it safe, all userspace tests not waiting for the end of the
transfer are now having a longer timeout: 2 minutes.

The Fixes commit was making the connection longer, but still, the
default timeout would have stopped it after 1 minute, which might not be
enough in very slow environments.

ae15506024 mptcp: fix duplicate reset on fastclose
The CI reports sporadic failures of the fastclose self-tests. The root
cause is a duplicate reset, not carrying the relevant MPTCP option.
In the failing scenario the bad reset is received by the peer before
the fastclose one, preventing the reception of the latter.

Indeed there is window of opportunity at fastclose time for the
following race:

  mptcp_do_fastclose
    __mptcp_close_ssk
      __tcp_close()
        tcp_set_state() [1]
        tcp_send_active_reset() [2]

After [1] the stack will send reset to in-flight data reaching the now
closed port. Such reset may race with [2].

Address the issue explicitly sending a single reset on fastclose before
explicitly moving the subflow to close status.

Formally decouple the two steps, ensuring that mptcp explicitly closes

17393fa7b7 mptcp: fix premature close in case of fallback
I'm observing very frequent self-tests failures in case of fallback when
running on a CONFIG_PREEMPT kernel.

The root cause is that subflow_sched_work_if_closed() closes any subflow
as soon as it is half-closed and has no incoming data pending.

That works well for regular subflows - MPTCP needs bi-directional
connectivity to operate on a given subflow - but for fallback socket is
race prone.

When TCP peer closes the connection before the MPTCP one,
subflow_sched_work_if_closed() will schedule the MPTCP worker to
gracefully close the subflow, and shortly after will do another schedule
to inject and process a dummy incoming DATA_FIN.

On CONFIG_PREEMPT kernel, the MPTCP worker can kick-in and close the
fallback subflow before subflow_sched_work_if_closed() is able to create
the dummy DATA_FIN, unexpectedly interrupting the transfer.

Address the issue explicitly avoiding closing fallback subflows on when
the peer is only half-closed.

Note that, when the subflow is able to create the DATA_FIN before the
worker invocation, the worker will change the msk state before trying to
close the subflow and will skip the latter operation as the msk will not
match anymore the precondition in __mptcp_close_subflow().

4f102d747c mptcp: avoid unneeded subflow-level drops
The rcv window is shared among all the subflows. Currently, MPTCP sync
the TCP-level rcv window with the MPTCP one at tcp_transmit_skb() time.

The above means that incoming data may sporadically observe outdated
TCP-level rcv window and being wrongly dropped by TCP.

Address the issue checking for the edge condition before queuing the
data at TCP level, and eventually syncing the rcv window as needed.

Note that the issue is actually present from the very first MPTCP
implementation, but backports older than the blamed commit below will
range from impossible to useless.

Before:

  $ nstat -n; sleep 1; nstat -z TcpExtBeyondWindow
  TcpExtBeyondWindow              14                 0.0

5e15395f6d mptcp: fix ack generation for fallback msk
mptcp_cleanup_rbuf() needs to know the last most recent, mptcp-level
rcv_wnd sent, and such information is tracked into the msk->old_wspace
field, updated at ack transmission time by mptcp_write_options().

Fallback socket do not add any mptcp options, such helper is never
invoked, and msk->old_wspace value remain stale. That in turn makes
ack generation at recvmsg() time quite random.

Address the issue ensuring mptcp_write_options() is invoked even for
fallback sockets, and just update the needed info in such a case.

The issue went unnoticed for a long time, as mptcp currently overshots
the fallback socket receive buffer autotune significantly. It is going
to change in the near future.

e837b9091b wifi: rtw89: hw_scan: Don't let the operating channel be last
Scanning can be offloaded to the firmware. To that end, the driver
prepares a list of channels to scan, including periodic visits back to
the operating channel, and sends the list to the firmware.

When the channel list is too long to fit in a single H2C message, the
driver splits the list, sends the first part, and tells the firmware to
scan. When the scan is complete, the driver sends the next part of the
list and tells the firmware to scan.

When the last channel that fit in the H2C message is the operating
channel something seems to go wrong in the firmware. It will
acknowledge receiving the list of channels but apparently it will not
do anything more. The AP can't be pinged anymore. The driver still
receives beacons, though.

One way to avoid this is to split the list of channels before the
operating channel.

Affected devices:

* RTL8851BU with firmware 0.29.41.3
* RTL8832BU with firmware 0.29.29.8
* RTL8852BE with firmware 0.29.29.8

The commit 57a5fbe39a ("wifi: rtw89: refactor flow that hw scan handles channel list")
is found by git blame, but it is actually to refine the scan flow, but not
a culprit, so skip Fixes tag.

295fe8406a spi: cadence-quadspi: Fix cqspi_probe() error handling for runtime pm
Commit f1eb4e792b ("spi: spi-cadence-quadspi: Enable pm runtime earlier
to avoid imbalance") relocated code but missed updating the error handling
path associated with it.

Prior to the relocation, runtime pm was enabled after the code-block
associated with 'cqspi_request_mmap_dma()', due to which, the error
handling for the same didn't require invoking 'pm_runtime_disable()'.

Post refactoring, runtime pm has been enabled before the code-block and
when an error is encountered, jumping to 'probe_dma_failed' doesn't
invoke 'pm_runtime_disable()'. This leads to a race condition wherein
'cqspi_runtime_suspend()' is invoked while the error handling path executes
in parallel. The resulting error is the following:

  clk:103:0 already disabled
  WARNING: drivers/clk/clk.c:1188 at clk_core_disable+0x80/0xa0, CPU#1: kworker/u8:0/12
  [TRIMMED]
  pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--)
  pc : clk_core_disable+0x80/0xa0
  lr : clk_core_disable+0x80/0xa0
  [TRIMMED]
  Call trace:
   clk_core_disable+0x80/0xa0 (P)
   clk_core_disable_lock+0x88/0x10c
   clk_disable+0x24/0x30
   cqspi_probe+0xa3c/0xae8
  [TRIMMED]

The error is due to the second invocation of 'clk_disable_unprepare()' on
'cqspi->clk' in the error handling within 'cqspi_probe()', with the first
invocation being within 'cqspi_runtime_suspend()'.

Fix this by correcting the error handling.

21f46f5476 drm/amdgpu/ttm: Fix crash when handling MMIO_REMAP in PDE flags
The MMIO_REMAP BO is a special 4K IO page that does not have a ttm_tt
behind it. However, amdgpu_ttm_tt_pde_flags() was treating it like
normal TT/doorbell/preempt memory and unconditionally accessed
ttm->caching. For the MMIO_REMAP BO, ttm is NULL, so this leads to a
NULL pointer dereference when computing PDE flags.

Fix this by checking that ttm is non-NULL before reading ttm->caching.
This prevents the crash for MMIO_REMAP and also makes the code more
defensive if other BOs ever come through without a ttm_tt.

80d8a9ad15 drm/amdgpu: Skip emit de meta data on gfx11 with rs64 enabled
[Why]
Accoreding to CP updated to RS64 on gfx11,
WRITE_DATA with PREEMPTION_META_MEMORY(dst_sel=8) is illegal for CP FW.
That packet is used for MCBP on F32 based system.
So it would lead to incorrect GRBM write and FW is not handling that
extra case correctly.

[How]
With gfx11 rs64 enabled, skip emit de meta data.

During the suspend sequence VPE is already going to be power gated
as part of vpe_suspend().  It's unnecessary to call during calls to

It actually can expose a race condition with the firmware if s0i3

807e0d187d tick/sched: Fix bogus condition in report_idle_softirq()
In commit 0345691b24 ("tick/rcu: Stop allowing RCU_SOFTIRQ in idle") the
new function report_idle_softirq() was created by breaking code out of the
existing can_stop_idle_tick() for kernels v5.18 and newer.

In doing so, the code essentially went from this form:

	if (A) {
		static int ratelimit;
		if (ratelimit < 10 && !C && A&D) {
                       pr_warn("NOHZ tick-stop error: ...");
		       ratelimit++;
		}
		return false;
	}

to a new function:

static bool report_idle_softirq(void)
{
       static int ratelimit;

       if (likely(!A))
               return false;

       if (ratelimit < 10)
               return false;
...
       pr_warn("NOHZ tick-stop error: local softirq work is pending, handler #%02x!!!\n",
               pending);
       ratelimit++;

       return true;
}

commit a7e282c777 ("tick/rcu: Fix bogus ratelimit condition") realized
ratelimit was essentially set to zero instead of ten, and hence *no*
softirq pending messages would ever be issued, but "fixed" it as:

-       if (ratelimit < 10)
+       if (ratelimit >= 10)
                return false;

However, this fix introduced another issue:

When ratelimit is greater than or equal 10, even if A is true, it will
directly return false. While ratelimit in the original code was only used
to control printing and will not affect the return value.

Restore the original logic and restrict ratelimit to control the printk and
not the return value.
