Jakub Kicinski b1987f1e05 Merge branch 'netconsole-reuse-netpoll_parse_ip_addr-in-configfs-helpers'
Breno Leitao says:

====================
netconsole: reuse netpoll_parse_ip_addr in configfs helpers

This patchset refactors the IP address parsing logic in the netconsole
driver to eliminate code duplication and improve maintainability. The
changes centralize IPv4 and IPv6 address parsing into a single function
(netpoll_parse_ip_addr). For that, it needs to teach
netpoll_parse_ip_addr() to handle strings with newlines, which is the
type of string coming from configfs.

Background

The netconsole driver currently has duplicate IP address parsing logic
in both local_ip_store() and remote_ip_store() functions. This
duplication increases the risk of inconsistencies and makes the code
harder to maintain.

Benefits

* Reduced code duplication: ~40 lines of duplicate parsing logic
  eliminated
 * Improved robustness: Centralized parsing reduces the chance
   of inconsistencies
 * Easier to maintain: Code follow more the netdev way

Breno Leitao 4aeb452c23 netconsole: use netpoll_parse_ip_addr in local_ip_store
Replace manual IP address parsing with a call to netpoll_parse_ip_addr
in remote_ip_store(), simplifying the code and reducing the chance of
errors.

The error message got removed, since it is not a good practice to
pr_err() if used pass a wrong value in configfs.

Breno Leitao 364213b736 netconsole: add support for strings with new line in netpoll_parse_ip_addr
The current IP address parsing logic fails when the input string
contains a trailing newline character. This can occur when IP
addresses are provided through configfs, which contains newlines in
a const buffer.

Teach netpoll_parse_ip_addr() how to ignore newlines at the end of the
IPs. Also, simplify the code by:

 * No need to check for separators. Try to parse ipv4, if it fails try
   ipv6 similarly to ceph_pton()
 * If ipv6 is not supported, don't call in6_pton() at all.

Breno Leitao fa38524ca5 netconsole: move netpoll_parse_ip_addr() earlier for reuse
Move netpoll_parse_ip_addr() earlier in the file to be reused in
other functions, such as local_ip_store(). This avoids duplicate
address parsing logic and centralizes validation for both IPv4
and IPv6 string input.

No functional changes intended.

Commit 16f5dfbc85 ("gfp: include __GFP_NOWARN in GFP_NOWAIT") made
GFP_NOWAIT implicitly include __GFP_NOWARN.

Therefore, explicit __GFP_NOWARN combined with GFP_NOWAIT (e.g.,
`GFP_NOWAIT | __GFP_NOWARN`) is now redundant.  Let's clean up these
redundant flags across subsystems.

No functional changes.

Wake Liu bc4c0a48bd selftests/net: Ensure assert() triggers in psock_tpacket.c
The get_next_frame() function in psock_tpacket.c was missing a return
statement in its default switch case, leading to a compiler warning.

This was caused by a `bug_on(1)` call, which is defined as an
`assert()`, being compiled out because NDEBUG is defined during the
build.

Instead of adding a `return NULL;` which would silently hide the error
and could lead to crashes later, this change restores the original
author's intent. By adding `#undef NDEBUG` before including <assert.h>,
we ensure the assertion is active and will cause the test to abort if
this unreachable code is ever executed.

Wake Liu c36748e873 selftests/net: Replace non-standard __WORDSIZE with sizeof(long) * 8
The `__WORDSIZE` macro, defined in the non-standard `<bits/wordsize.h>`
header, is a GNU extension and not universally available with all
toolchains, such as Clang when used with musl libc.

This can lead to build failures in environments where this header is
missing.

The intention of the code is to determine the bit width of a C `long`.
Replace the non-portable `__WORDSIZE` with the standard and portable
`sizeof(long) * 8` expression to achieve the same result.

This change also removes the inclusion of the now-unused
`<bits/wordsize.h>` header.

Filipe Manana 0a32e4f002 btrfs: fix log tree replay failure due to file with 0 links and extents
If we log a new inode (not persisted in a past transaction) that has 0
links and extents, then log another inode with an higher inode number, we
end up with failing to replay the log tree with -EINVAL. The steps for
this are:

1) create new file A
2) write some data to file A
3) open an fd on file A
4) unlink file A
5) fsync file A using the previously open fd
6) create file B (has higher inode number than file A)
7) fsync file B
8) power fail before current transaction commits

Now when attempting to mount the fs, the log replay will fail with
-ENOENT at replay_one_extent() when attempting to replay the first
extent of file A. The failure comes when trying to open the inode for
file A in the subvolume tree, since it doesn't exist.

Before commit 5f61b96159 ("btrfs: fix inode lookup error handling
during log replay"), the returned error was -EIO instead of -ENOENT,
since we converted any errors when attempting to read an inode during
log replay to -EIO.

The reason for this is that the log replay procedure fails to ignore
the current inode when we are at the stage LOG_WALK_REPLAY_ALL, our
current inode has 0 links and last inode we processed in the previous
stage has a non 0 link count. In other words, the issue is that at
replay_one_extent() we only update wc->ignore_cur_inode if the current
replay stage is LOG_WALK_REPLAY_INODES.

Fix this by updating wc->ignore_cur_inode whenever we find an inode item
regardless of the current replay stage. This is a simple solution and easy
to backport, but later we can do other alternatives like avoid logging
extents or inode items other than the inode item for inodes with a link
count of 0.

The problem with the wc->ignore_cur_inode logic has been around since
commit f2d72f42d5 ("Btrfs: fix warning when replaying log after fsync
of a tmpfile") but it only became frequent to hit since the more recent
commit 5e85262e54 ("btrfs: fix fsync of files with no hard links not
persisting deletion"), because we stopped skipping inodes with a link
count of 0 when logging, while before the problem would only be triggered
if trying to replay a log tree created with an older kernel which has a
logged inode with 0 links.

A test case for fstests will be submitted soon.

   environments because of the error that is now returned when writing

a crash when OPP tables are not present in device tree.

Unable to handle kernel access to user memory outside uaccess routines

...
pc : dev_pm_opp_put+0x1c/0x4c
lr : core_clks_enable+0x4c/0x16c [venus_core]

Add IS_ERR() checks before calling dev_pm_opp_put() to avoid
dereferencing error pointers.

Linus Torvalds adf12a394c Merge tag 'perf-fixes-27504' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git
Pull perf fixes from Thomas Gleixner:
 "Perf fixes for perf_mmap() reference counting to prevent potential
  reference count leaks which are caused by:

   - VMA splits, which change the offset or size of a mapping, which
     causes perf_mmap_close() to ignore the unmap or unmap the wrong
     buffer.

   - Several internal issues of perf_mmap(), which can cause reference
     count leaks in the perf mmap, corrupt accounting or cause leaks in
     perf drivers.

  The main fix is to prevent VMA splits by implementing the
  [may_]split() callback for vm operations.

  The other issues are addressed by rearranging code, early returns on
  failure and invocation of cleanups.

  Also provide a selftest to validate the fixes.

  The reference counting should be converted to refcount_t, but that
  requires larger refactoring of the code and will be done once these
  fixes are upstream"

Ammar Faizi 8466d39370 net: usbnet: Fix the wrong netif_carrier_on() call
The commit referenced in the Fixes tag causes usbnet to malfunction
(identified via git bisect). Post-commit, my external RJ45 LAN cable
fails to connect. Linus also reported the same issue after pulling that
commit.

The code has a logic error: netif_carrier_on() is only called when the
link is already on. Fix this by moving the netif_carrier_on() call
outside the if-statement entirely. This ensures it is always called
when EVENT_LINK_CARRIER_ON is set and properly clears it regardless
of the link state.

Masahiro Yamada 8d6841d5cb MAINTAINERS: hand over Kbuild maintenance
I'm stepping down as the maintainer of Kbuild/Kconfig.
It was enjoyable to refactor and improve the kernel build system,
but due to personal reasons, I believe it's difficult for me to
continue in this role any further.

I discussed this off-list with Nathan and Nicolas, and they have
kindly agreed to take over the maintenance of Kbuild with Odd Fixes.
I'm grateful to them for stepping in.

As for Kconfig, there are currently no designated reviewers, so the
maintainer position will remain vacant for now. I hope someone will
step up to take on the role.

Michał Górny 73d210e9fa kheaders: make it possible to override TAR
Commit 86cdd2fdc4 ("kheaders: make headers archive reproducible")
introduced a number of options specific to GNU tar to the `tar`
invocation in `gen_kheaders.sh` script. This causes the script to fail
to work on systems where `tar` is not GNU tar. This can occur e.g.
on recent Gentoo Linux installations that support using bsdtar from
libarchive instead.

Add a `TAR` make variable to make it possible to override the tar
executable used, e.g. by specifying:

  make TAR=gtar
