e576e7843c ALSA: ctxfi: Simplify dao_clear_{left,right}_input() functions
There was a lote of code duplication in the dao_clear_left_input() and
dao_clear_right_input() functions. A new function, dao_clear_input(),
was created and now the left and right functions call it instead of
repeating themselves.

69146a8c89 ubi: ubi_get_ec_info: Fix compiling error 'cast specifies array type'
On risc V platform, there is a type conversion for the return value
(unsigned long type) of __untagged_addr_remote() in function
untagged_addr(). The compiler will complain when the parameter 'addr'
is an array type:
  arch/riscv/include/asm/uaccess.h:33:9: error: cast specifies array type
  (__force  __typeof__(addr))__untagged_addr_remote(current->mm, __addr)

Fix it by converting the input parameter as a pointer.

5293b5f97e Merge branch 'vsnprintf'
This merges the vsnprintf internal cleanups I did, which were triggered
by a combination of performance issues (see for example commit
f9ed1f7c2e: "genirq/proc: Use seq_put_decimal_ull_width() for decimal
values") and discussion about tracing abusing the vsnprintf code in odd
ways.

The intent was to improve code generation, but also to possibly
eventually expose the cleaned-up printf format decoding state machine.

It certainly didn't get to the point where we'd want to expose the
format decoding to external users, but it's an improvement over what we
used to have.  Several of the complex case statements have been
simplified, or removed entirely to be replaced by simple table lookups.

* branch 'vsnprintf':
  vsnprintf: fix the number base for non-numeric formats
  vsnprintf: fix up kerneldoc for argument name changes
  vsprintf: don't make the 'binary' version pack small integer arguments
  vsnprintf: collapse the number format state into one single state
  vsnprintf: mark the indirect width and precision cases unlikely
  vsnprintf: inline skip_atoi() again
  vsprintf: deal with format specifiers with a lookup table
  vsprintf: deal with format flags with a simple lookup table
  vsprintf: associate the format state with the format pointer
  vsprintf: fix calling convention for format_decode()
  vsprintf: avoid nested switch statement on same variable
  vsprintf: simplify number handling

b489e79466 PM / OPP: Add reference counting helpers for Rust implementation
To ensure that resources such as OPP tables or OPP nodes are not freed
while in use by the Rust implementation, it is necessary to increment
their reference count from Rust code.

This commit introduces a new helper function,
dev_pm_opp_get_opp_table_ref(), to increment the reference count of an
OPP table and declares the existing helper dev_pm_opp_get() in pm_opp.h.

10e6fe53d9 cifs: Do not attempt to call CIFSGetSrvInodeNumber() without CAP_INFOLEVEL_PASSTHRU
CIFSGetSrvInodeNumber() uses SMB_QUERY_FILE_INTERNAL_INFO (0x3ee) level
which is SMB PASSTHROUGH level (>= 0x03e8). SMB PASSTHROUGH levels are
supported only when server announce CAP_INFOLEVEL_PASSTHRU.

So add guard in cifs_query_file_info() function which is the only user of
CIFSGetSrvInodeNumber() function and returns -EOPNOTSUPP when server does
not announce CAP_INFOLEVEL_PASSTHRU.

6d08851c60 cifs: Fix printing Status code into dmesg
NT Status code is 32-bit number, so for comparing two NT Status codes is
needed to check all 32 bits, and not just low 24 bits.

Before this change kernel printed message:
"Status code returned 0x8000002d NT_STATUS_NOT_COMMITTED"

It was incorrect as because NT_STATUS_NOT_COMMITTED is defined as
0xC000002d and 0x8000002d has defined name NT_STATUS_STOPPED_ON_SYMLINK.

With this change kernel prints message:
"Status code returned 0x8000002d NT_STATUS_STOPPED_ON_SYMLINK"

215b7f9ecb smb: client: correctly handle ErrorContextData as a flexible array
The `smb2_symlink_err_rsp` structure was previously defined with
`ErrorContextData` as a single `__u8` byte. However, the `ErrorContextData`
field is intended to be a variable-length array based on `ErrorDataLength`.
This mismatch leads to incorrect pointer arithmetic and potential memory
access issues when processing error contexts.

Updates the `ErrorContextData` field to be a flexible array
(`__u8 ErrorContextData[]`). Additionally, it modifies the corresponding
casts in the `symlink_data()` function to properly handle the flexible
array, ensuring correct memory calculations and data handling.

These changes improve the robustness of SMB2 symlink error processing.

48aa99523e smb: client: don't retry DFS targets on server shutdown
If TCP Server is about to be destroyed (e.g. CifsExiting was set) and
it is reconnecting, stop retrying DFS targets from cached DFS referral
as this would potentially delay server shutdown in several seconds.

retry same link referral on a different root server.  Set an end

ad46faff1a smb: client: fix DFS mount against old servers with NTLMSSP
Old Windows servers will return not fully qualified DFS targets by
default as specified in

  MS-DFSC 3.2.5.5 Receiving a Root Referral Request or Link Referral
  Request

    | Servers SHOULD<30> return fully qualified DNS host names of
    | targets in responses to root referral requests and link referral
    | requests.
    | ...
    | <30> Section 3.2.5.5: By default, Windows Server 2003, Windows
    | Server 2008, Windows Server 2008 R2, Windows Server 2012, and
    | Windows Server 2012 R2 return DNS host names that are not fully
    | qualified for targets.

Fix this by converting all NetBIOS host names from DFS targets to
FQDNs and try resolving them first if DNS domain name was provided in
NTLMSSP CHALLENGE_MESSAGE message from previous SMB2_SESSION_SETUP.
This also prevents the client from translating the DFS target
hostnames to another domain depending on the network domain search
order.

361cb056e2 wifi: rtw89: Correct immediate cfg_len calculation for scan_offload_be
Ensures the correct calculation of `cfg_len` prior to the allocation of
the skb in the `rtw89_fw_h2c_scan_offload_be` function, particularly when
the `SCAN_OFFLOAD_BE_V0` firmware feature is enabled. It addresses an
issue where an incorrect skb size might be allocated due to a delayed
setting of `cfg_len`, potentially leading to memory inefficiencies.

By moving the conditional check and assignment of `cfg_len` before skb
allocation, the patch guarantees that `len`, which depends on `cfg_len`,
is accurately computed, ensuring proper skb size and preventing any
unnecessary memory reservation for firmware operations not supporting
beyond the `w8` member of the command data structure.

This correction helps to optimize memory usage and maintain consistent
behavior across different firmware versions.

ccb7276a6d batman-adv: fix panic during interface removal
Reference counting is used to ensure that
batadv_hardif_neigh_node and batadv_hard_iface
are not freed before/during
batadv_v_elp_throughput_metric_update work is
finished.

But there isn't a guarantee that the hard if will
remain associated with a soft interface up until
the work is finished.

This fixes a crash triggered by reboot that looks
like this:

Call trace:
 batadv_v_mesh_free+0xd0/0x4dc [batman_adv]
 batadv_v_elp_throughput_metric_update+0x1c/0xa4
 process_one_work+0x178/0x398
 worker_thread+0x2e8/0x4d0
 kthread+0xd8/0xdc
 ret_from_fork+0x10/0x20

(the batadv_v_mesh_free call is misleading,
and does not actually happen)

I was able to make the issue happen more reliably
by changing hardif_neigh->bat_v.metric_work work
to be delayed work. This allowed me to track down
and confirm the fix.

The cpumask_any*() APIs comment states that it returns a "random" cpu
within the given cpumask. However it's not actually random as random
itself stands a meaning for uniform distribution.

cpumask_any*() APIs are a naming convention for the caller to states that
it doesn't care which CPU it gets, so change "random" to "arbitrary" would
be more appropriate.

drm/vc4: Remove BOs seqnos
`bo->seqno`, `bo->write_seqno`, and `exec->bin_dep_seqno` are leftovers
from a time when VC4 didn't support DMA Reservation Objects. Before DMA
Resv was introduced, tracking the correspondence between BOs and jobs
through the job's seqno made sense.

However, this is no longer needed, as VC4 now supports DMA Reservation
Objects and attaches the "job done" fence to the BOs. Therefore, remove
the BOs seqnos in favor of using DMA Resv Objects.

 - Do not adjust the weight of empty group entities and avoid
   scheduling artifacts

 - Avoid scheduling lag by computing lag properly and thus address
   an EEVDF entity placement issue

fd3aa3d5e5 selftests/efivarfs: fix tests for failed write removal
The current self tests expect the zero size remnants that failed
variable creation leaves.  Update the tests to verify these are now
absent.

908af31f48 efivarfs: fix error on write to new variable leaving remnants
Make variable cleanup go through the fops release mechanism and use
zero inode size as the indicator to delete the file.  Since all EFI
variables must have an initial u32 attribute, zero size occurs either
because the update deleted the variable or because an unsuccessful
write after create caused the size never to be set in the first place.
In the case of multiple racing opens and closes, the open is counted
to ensure that the zero size check is done on the last close.

Even though this fixes the bug that a create either not followed by a
write or followed by a write that errored would leave a remnant file
for the variable, the file will appear momentarily globally visible
until the last close of the fd deletes it.  This is safe because the
normal filesystem operations will mediate any races; however, it is
still possible for a directory listing at that instant between create
and close contain a zero size variable that doesn't exist in the EFI
table.

a58e954464 efivarfs: remove unused efivarfs_list
Remove all function helpers and mentions of the efivarfs_list now that
all consumers of the list have been removed and entry management goes
exclusively through the inode.
