173217bd73 smb3: retrying on failed server close
In the current implementation, CIFS close sends a close to the
server and does not check for the success of the server close.
This patch adds functionality to check for server close return
status and retries in case of an EBUSY or EAGAIN error.

This can help avoid handle leaks

de164a7f19 nios2: Only use built-in devicetree blob if configured to do so
Starting with commit 7b937cc243 ("of: Create of_root if no dtb provided
by firmware"), attempts to boot nios2 images with an external devicetree
blob result in a crash.

Kernel panic - not syncing: early_init_dt_alloc_memory_arch:
	Failed to allocate 72 bytes align=0x40

For nios2, a built-in devicetree blob always overrides devicetree blobs
provided by ROMMON/BIOS. This includes the new dummy devicetree blob.
Result is that the dummy devicetree blob is used even if an external
devicetree blob is provided. Since the dummy devicetree blob does not
include any memory information, memory allocations fail, resulting in
the crash.

To fix the problem, only use the built-in devicetree blob if
CONFIG_NIOS2_DTB_SOURCE_BOOL is enabled.

43f5ea4646 bcachefs: Topology repair now uses nodes found by scanning to fill holes
With the new btree node scan code, we can now recover from corrupt btree
roots - simply create a new fake root at depth 1, and then insert all
the leaves we found.

If the root wasn't corrupt but there's corruption elsewhere in the
btree, we can fill in holes as needed with the newest version of a given
node(s) from the scan; we also check if a given btree node is older than
what we found from the scan.

4409b8081d bcachefs: Repair pass for scanning for btree nodes
If a btree root or interior btree node goes bad, we're going to lose a
lot of data, unless we can recover the nodes that it pointed to by
scanning.

Fortunately btree node headers are fully self describing, and
additionally the magic number is xored with the filesytem UUID, so we
can do so safely.

This implements the scanning - next patch will rework topology repair to
make use of the found nodes.

drm/i915/mst: Limit MST+DSC to TGL+
The MST code currently assumes that glk+ already supports MST+DSC,
which is incorrect. We need to check for TGL+ actually. ICL does
support SST+DSC, but supposedly it can't do MST+FEC which will
also rule out MST+DSC.

Note that a straight TGL+ check doesn't work here because DSC
support can get fused out, so we do need to also check 'has_dsc'.

701b38995e security: Place security_path_post_mknod() where the original IMA call was
Commit 08abce60d6 ("security: Introduce path_post_mknod hook")
introduced security_path_post_mknod(), to replace the IMA-specific call
to ima_post_path_mknod().

For symmetry with security_path_mknod(), security_path_post_mknod() was
called after a successful mknod operation, for any file type, rather
than only for regular files at the time there was the IMA call.

However, as reported by VFS maintainers, successful mknod operation does
not mean that the dentry always has an inode attached to it (for
example, not for FIFOs on a SAMBA mount).

If that condition happens, the kernel crashes when
security_path_post_mknod() attempts to verify if the inode associated to
the dentry is private.

Move security_path_post_mknod() where the ima_post_path_mknod() call was,
which is obviously correct from IMA/EVM perspective. IMA/EVM are the only
in-kernel users, and only need to inspect regular files.

0e11073247 x86/retpoline: Do the necessary fixup to the Zen3/4 srso return thunk for !SRSO
The srso_alias_untrain_ret() dummy thunk in the !CONFIG_MITIGATION_SRSO
case is there only for the altenative in CALL_UNTRAIN_RET to have
a symbol to resolve.

However, testing with kernels which don't have CONFIG_MITIGATION_SRSO
enabled, leads to the warning in patch_return() to fire:

  missing return thunk: srso_alias_untrain_ret+0x0/0x10-0x0: eb 0e 66 66 2e
  WARNING: CPU: 0 PID: 0 at arch/x86/kernel/alternative.c:826 apply_returns (arch/x86/kernel/alternative.c:826

Put in a plain "ret" there so that gcc doesn't put a return thunk in
in its place which special and gets checked.

In addition:

  ERROR: modpost: "srso_alias_untrain_ret" [arch/x86/kvm/kvm-amd.ko] undefined!
  make[2]: *** [scripts/Makefile.modpost:145: Module.symvers] Chyba 1
  make[1]: *** [/usr/src/linux-6.8.3/Makefile:1873: modpost] Chyba 2
  make: *** [Makefile:240: __sub-make] Chyba 2

since !SRSO builds would use the dummy return thunk as reported by
petr.pisar@atlas.cz, https://bugzilla.kernel.org/show_bug.cgi?id=218679.

ena_rx_filtering to inner_vlan_ops in DVM mode.
This causes an error when rx_filtering cannot be enabled in legacy mode.

da781936e7 thermal: gov_power_allocator: Allow binding without trip points
IPA probe function was recently refactored to perform extra error checks
and make sure the thermal zone has trip points necessary for the IPA
operation. With this change, if a thermal zone is probed such that it
has no trip points that IPA can use, IPA will fail and the TZ won't be
created. This is the case if a platform defines a TZ without cooling
devices and only with "hot"/"critical" trip points, often found on some
Qualcomm devices [1].

Documentation across IPA code (notably get_governor_trips() kerneldoc)
suggests that IPA is supposed to handle such TZ even if it won't
actually do anything.

This commit partially reverts the previous change to allow IPA to bind
to such "empty" thermal zones.

1057c4c36e thermal: gov_power_allocator: Allow binding without cooling devices
IPA was recently refactored to split out memory allocation into a
separate funciton. That funciton was made to return -EINVAL if there is
zero power_actors and thus no memory to allocate. This causes IPA to
fail probing when the thermal zone has no attached cooling devices.

Since cooling devices can attach after the thermal zone is created and
the governer is attached to it, failing probe due to the lack of cooling
devices is incorrect.

Change the allocate_actors_buffer() to return success when there is no
cooling devices present.

b017a0cea6 arm64/ptrace: Use saved floating point state type to determine SVE layout
The SVE register sets have two different formats, one of which is a wrapped
version of the standard FPSIMD register set and another with actual SVE
register data. At present we check TIF_SVE to see if full SVE register
state should be provided when reading the SVE regset but if we were in a
syscall we may have saved only floating point registers even though that is
set.

Fix this and simplify the logic by checking and using the format which we
recorded when deciding if we should use FPSIMD or SVE format.
