04e6ce8f06 ext4: mark fc as ineligible using an handle in ext4_xattr_set()
Calling ext4_fc_mark_ineligible() with a NULL handle is racy and may result
in a fast-commit being done before the filesystem is effectively marked as
ineligible.  This patch moves the call to this function so that an handle
can be used.  If a transaction fails to start, then there's not point in
trying to mark the filesystem as ineligible, and an error will eventually be
returned to user-space.

faab35a037 ext4: use handle to mark fc as ineligible in __track_dentry_update()
Calling ext4_fc_mark_ineligible() with a NULL handle is racy and may result
in a fast-commit being done before the filesystem is effectively marked as
ineligible.  This patch fixes the calls to this function in
__track_dentry_update() by adding an extra parameter to the callback used in
ext4_fc_track_template().

 - Force position-independent veneers - in some kernel configurations,
   the LLD linker generates position-dependent veneers for otherwise

622a3ed1ac Various fixes for tracing:
- Fix tp_printk command line option crashing the kernel
 
   With the code that can handle a buffer from a previous boot, the
   trace_check_vprintf() needed access to the delta of the address
   space used by the old buffer and the current buffer. To do so,
   the trace_array (tr) parameter was used. But when tp_printk is
   enabled on the kernel command line, no trace buffer is used and
   the trace event is sent directly to printk(). That meant the tr
   field of the iterator descriptor was NULL, and since tp_printk still
   uses trace_check_vprintf() it caused a NULL dereference.
 
 - Add ptrace.h include to x86 ftrace file for completeness
 
 - Fix rtla installation when done with out-of-tree build
 
 - Fix the help messages in rtla that were incorrect
 
 - Several fixes to fix races with the timerlat and hwlat code
 
   Several locking issues were discovered with the coordination
   between timerlat kthread creation and hotplug. As timerlat has
   callbacks from hotplug code to start kthreads when CPUs come online.
   There are also locking issues with grabbing the cpu_read_lock()
   and the locks within timerlat.

2f91ff27b0 sound fixes for 6.12-rc2
Slightly high amount of changes in this round, partly because of my
 vacation in the last weeks.  But all changes are small and nothing
 looks worrisome.
 
 The biggest LOCs is MAINTAINERS updates, and there is a core change
 for card-ID string creation for non-ASCII inputs.  Others are rather
 device-specific, such as new quirks and device IDs for ASoC, usual
 HD-audio and USB-audio quirks and fixes, as well as regression fixes
 in HD-audio HDMI audio and Conexant codec.

 - Fix an error path memory leak, if one part fails to allocate.
   Obviously not something that'll generally hit without error

 - Fix an io_req_flags_t cast to make sparse happier.

 - Improve the recv multishot termination. Not a bug now, but could be
   one in the future. This makes it do the same thing that recvmsg does
   in terms of when to terminate a request or not.

c5e3cdbf2a tomoyo: revert CONFIG_SECURITY_TOMOYO_LKM support
This patch reverts two TOMOYO patches that were merged into Linus' tree
during the v6.12 merge window:

8b985bbfab ("tomoyo: allow building as a loadable LSM module")
268225a1de ("tomoyo: preparation step for building as a loadable LSM module")

Together these two patches introduced the CONFIG_SECURITY_TOMOYO_LKM
Kconfig build option which enabled a TOMOYO specific dynamic LSM loading
mechanism (see the original commits for more details).  Unfortunately,
this approach was widely rejected by the LSM community as well as some
members of the general kernel community.  Objections included concerns
over setting a bad precedent regarding individual LSMs managing their
LSM callback registrations as well as general kernel symbol exporting
practices.  With little to no support for the CONFIG_SECURITY_TOMOYO_LKM
approach outside of Tetsuo, and multiple objections, we need to revert
these changes.

b3ebb00706 ALSA: hda/conexant: Fix conflicting quirk for System76 Pangolin
We received a regression report for System76 Pangolin (pang14) due to
the recent fix for Tuxedo Sirius devices to support the top speaker.
The reason was the conflicting PCI SSID, as often seen.

As a workaround, now the codec SSID is checked and the quirk is
applied conditionally only to Sirius devices.

3840cbe24c sched: psi: fix bogus pressure spikes from aggregation race
Brandon reports sporadic, non-sensical spikes in cumulative pressure
time (total=) when reading cpu.pressure at a high rate. This is due to
a race condition between reader aggregation and tasks changing states.

While it affects all states and all resources captured by PSI, in
practice it most likely triggers with CPU pressure, since scheduling
events are so frequent compared to other resource events.

The race context is the live snooping of ongoing stalls during a
pressure read. The read aggregates per-cpu records for stalls that
have concluded, but will also incorporate ad-hoc the duration of any
active state that hasn't been recorded yet. This is important to get
timely measurements of ongoing stalls. Those ad-hoc samples are
calculated on-the-fly up to the current time on that CPU; since the
stall hasn't concluded, it's expected that this is the minimum amount
of stall time that will enter the per-cpu records once it does.

The problem is that the path that concludes the state uses a CPU clock
read that is not synchronized against aggregators; the clock is read
outside of the seqlock protection. This allows aggregators to race and
snoop a stall with a longer duration than will actually be recorded.

With the recorded stall time being less than the last snapshot
remembered by the aggregator, a subsequent sample will underflow and
observe a bogus delta value, resulting in an erratic jump in pressure.

Fix this by moving the clock read of the state change into the seqlock
protection. This ensures no aggregation can snoop live stalls past the
time that's recorded when the state concludes.

fcd1ec9cb5 KVM: x86/mmu: fix KVM_X86_QUIRK_SLOT_ZAP_ALL for shadow MMU
As was tried in commit 4e103134b8 ("KVM: x86/mmu: Zap only the relevant
pages when removing a memslot"), all shadow pages, i.e. non-leaf SPTEs,
need to be zapped.  All of the accounting for a shadow page is tied to the
memslot, i.e. the shadow page holds a reference to the memslot, for all
intents and purposes.  Deleting the memslot without removing all relevant
shadow pages, as is done when KVM_X86_QUIRK_SLOT_ZAP_ALL is disabled,
results in NULL pointer derefs when tearing down the VM.

Reintroduce from that commit the code that walks the whole memslot when
there are active shadow MMU pages.

```

After tracing the scheduling event, it was discovered that the migration
of the "timerlat/1" thread was performed during thread creation. Further
analysis confirmed that it is because the CPU online processing for
osnoise is implemented through workers, which is asynchronous with the
offline processing. When the worker was scheduled to create a thread, the
CPU may has already been removed from the cpu_online_mask during the offline
process, resulting in the inability to select the right CPU:

T1                       | T2
[CPUHP_ONLINE]           | cpu_device_down()
osnoise_hotplug_workfn() |
                         |     cpus_write_lock()
                         |     takedown_cpu(1)

    cpus_read_lock()     |
    start_kthread(1)     |
    cpus_read_unlock()   |

To fix this, skip online processing if the CPU is already offline.

b484a02c9c tracing/timerlat: Drop interface_lock in stop_kthread()
stop_kthread() is the offline callback for "trace/osnoise:online", since
commit 5bfbcd1ee5 ("tracing/timerlat: Add interface_lock around clearing
of kthread in stop_kthread()"), the following ABBA deadlock scenario is
introduced:

T1                            | T2 [BP]               | T3 [AP]
osnoise_hotplug_workfn()      | work_for_cpu_fn()     | cpuhp_thread_fun()
                              |   _cpu_down()         |   osnoise_cpu_die()
  mutex_lock(&interface_lock) |                       |     stop_kthread()
                              |     cpus_write_lock() |       mutex_lock(&interface_lock)
  cpus_read_lock()            |     cpuhp_kick_ap()   |

As the interface_lock here in just for protecting the "kthread" field of
the osn_var, use xchg() instead to fix this issue. Also use
for_each_online_cpu() back in stop_per_cpu_kthreads() as it can take
cpu_read_lock() again.

offline repeatedly and is invoked for multiple times after a certain
online.

This will lead to kthread leak and timer corruption. Add a check
in start_kthread() to prevent this situation.

50a3242d84 tracing: Fix trace_check_vprintf() when tp_printk is used
When the tp_printk kernel command line is used, the trace events go
directly to printk(). It is still checked via the trace_check_vprintf()
function to make sure the pointers of the trace event are legit.

The addition of reading buffers from previous boots required adding a
delta between the addresses of the previous boot and the current boot so
that the pointers in the old buffer can still be used. But this required
adding a trace_array pointer to acquire the delta offsets.

The tp_printk code does not provide a trace_array (tr) pointer, so when
the offsets were examined, a NULL pointer dereference happened and the
kernel crashed.

If the trace_array does not exist, just default the delta offsets to zero,
as that also means the trace event is not being read from a previous boot.

7b99b5ab88 gpiolib: Fix potential NULL pointer dereference in gpiod_get_label()
In `gpiod_get_label()`, it is possible that `srcu_dereference_check()` may
return a NULL pointer, leading to a scenario where `label->str` is accessed
without verifying if `label` itself is NULL.

This patch adds a proper NULL check for `label` before accessing
`label->str`. The check for `label->str != NULL` is removed because
`label->str` can never be NULL if `label` is not NULL.

This fixes the issue where the label name was being printed as `(efault)`
when dumping the sysfs GPIO file when `label == NULL`.

a1d402abf8 KVM: arm64: Fix kvm_has_feat*() handling of negative features
Oliver reports that the kvm_has_feat() helper is not behaviing as
expected for negative feature. On investigation, the main issue
seems to be caused by the following construct:

 #define get_idreg_field(kvm, id, fld)				\
 	(id##_##fld##_SIGNED ?					\
	 get_idreg_field_signed(kvm, id, fld) :			\
	 get_idreg_field_unsigned(kvm, id, fld))

where one side of the expression evaluates as something signed,
and the other as something unsigned. In retrospect, this is totally
braindead, as the compiler converts this into an unsigned expression.
When compared to something that is 0, the test is simply elided.

Epic fail. Similar issue exists in the expand_field_sign() macro.

The correct way to handle this is to chose between signed and unsigned
comparisons, so that both sides of the ternary expression are of the
same type (bool).

In order to keep the code readable (sort of), we introduce new
comparison primitives taking an operator as a parameter, and
rewrite the kvm_has_feat*() helpers in terms of these primitives.

d3a49f6091 cifs: Do not convert delimiter when parsing NFS-style symlinks
NFS-style symlinks have target location always stored in NFS/UNIX form
where backslash means the real UNIX backslash and not the SMB path
separator.

So do not mangle slash and backslash content of NFS-style symlink during
readlink() syscall as it is already in the correct Linux form.

This fixes interoperability of NFS-style symlinks with backslashes created
by Linux NFS3 client throw Windows NFS server and retrieved by Linux SMB
client throw Windows SMB server, where both Windows servers exports the
same directory.

e2a8910af0 cifs: Fix buffer overflow when parsing NFS reparse points
ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.

Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract
variable len.

Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.

Major and minor rdev values are present also only when reparse buffer is
large enough. Check for reparse buffer size before calling reparse_mkdev().

Otherwise, next time when calling sctp_inet_listen(), if sctp_sk(sk)->reuse
is already set via setsockopt(SCTP_REUSE_PORT), sctp_sk(sk)->bind_hash will
be dereferenced as sk_state is LISTENING, which causes a crash as bind_hash

There is a bug in schema, current examples contain 64-bit
addressing as well as 32-bit addressing. The schema validation
does pass incidentally considering one 64-bit reg address as
two 32-bit reg address entries. If we change axi_ethernet_eth1
example node reg addressing to 32-bit schema validation reports:

Documentation/devicetree/bindings/net/xlnx,axi-ethernet.example.dtb:
ethernet@40000000: reg: [[1073741824, 262144]] is too short

To fix it add missing reg minItems constraints and to make things clearer
stick to 32-bit addressing in examples.
