The order of parameters can be traced back all the way to 6ac99e8

In v6.10-rc1, a different commit 2c321f3 ("mm: change inlined
allocation helpers to account at the call site") however exposed the
order of args in a way that gcc-14 has enough visibility to start
warning about it, because (in !CONFIG_MEMCG case) bpf_map_kvcalloc is
then a macro alias for kvcalloc instead of a static inline wrapper.

To sum up the warning happens when the following conditions are all met:

- gcc-14 is used (didn't see it with gcc-13)
- commit 2c321f3 is present
- CONFIG_MEMCG is not enabled in .config
- CONFIG_WERROR turns this from a compiler warning to error

Given a schedule:

timer1 cb			timer2 cb

bpf_timer_cancel(timer2);	bpf_timer_cancel(timer1);

Both bpf_timer_cancel calls would wait for the other callback to finish
executing, introducing a lockup.

Add an atomic_t count named 'cancelling' in bpf_hrtimer. This keeps
track of all in-flight cancellation requests for a given BPF timer.
Whenever cancelling a BPF timer, we must check if we have outstanding
cancellation requests, and if so, we must fail the operation with an
error (-EDEADLK) since cancellation is synchronous and waits for the
callback to finish executing. This implies that we can enter a deadlock
situation involving two or more timer callbacks executing in parallel
and attempting to cancel one another.

Note that we avoid incrementing the cancelling counter for the target
timer (the one being cancelled) if bpf_timer_cancel is not invoked from
a callback, to avoid spurious errors. The whole point of detecting
cur->cancelling and returning -EDEADLK is to not enter a busy wait loop
(which may or may not lead to a lockup). This does not apply in case the
caller is in a non-callback context, the other side can continue to
cancel as it sees fit without running into errors.

Background on prior attempts:

Earlier versions of this patch used a bool 'cancelling' bit and used the
following pattern under timer->lock to publish cancellation status.

lock(t->lock);
t->cancelling = true;
mb();
if (cur->cancelling)
	return -EDEADLK;
unlock(t->lock);
hrtimer_cancel(t->timer);
t->cancelling = false;

The store outside the critical section could overwrite a parallel
requests t->cancelling assignment to true, to ensure the parallely
executing callback observes its cancellation status.

It would be necessary to clear this cancelling bit once hrtimer_cancel
is done, but lack of serialization introduced races. Another option was
explored where bpf_timer_start would clear the bit when (re)starting the
timer under timer->lock. This would ensure serialized access to the
cancelling bit, but may allow it to be cleared before in-flight
hrtimer_cancel has finished executing, such that lockups can occur
again.

Thus, we choose an atomic counter to keep track of all outstanding
cancellation requests and use it to prevent lockups in case callbacks
attempt to cancel each other while executing in parallel.

Currently, the same case as previous patch (two timer callbacks trying
to cancel each other) can be invoked through bpf_map_update_elem as
well, or more precisely, freeing map elements containing timers. Since
this relies on hrtimer_cancel as well, it is prone to the same deadlock
situation as the previous patch.

It would be sufficient to use hrtimer_try_to_cancel to fix this problem,
as the timer cannot be enqueued after async_cancel_and_free. Once
async_cancel_and_free has been done, the timer must be reinitialized
before it can be armed again. The callback running in parallel trying to
arm the timer will fail, and freeing bpf_hrtimer without waiting is
sufficient (given kfree_rcu), and bpf_timer_cb will return
HRTIMER_NORESTART, preventing the timer from being rearmed again.

However, there exists a UAF scenario where the callback arms the timer
before entering this function, such that if cancellation fails (due to
timer callback invoking this routine, or the target timer callback
running concurrently). In such a case, if the timer expiration is
significantly far in the future, the RCU grace period expiration
happening before it will free the bpf_hrtimer state and along with it
the struct hrtimer, that is enqueued.

Hence, it is clear cancellation needs to occur after
async_cancel_and_free, and yet it cannot be done inline due to deadlock
issues. We thus modify bpf_timer_cancel_and_free to defer work to the
global workqueue, adding a work_struct alongside rcu_head (both used at
_different_ points of time, so can share space).

Update existing code comments to reflect the new state of affairs.

Kumar Kartikeya Dwivedi says:

====================
Fixes for BPF timer lockup and UAF

The following patches contain fixes for timer lockups and a
use-after-free scenario.

This set proposes to fix the following lockup situation for BPF timers.

CPU 1					CPU 2

bpf_timer_cb				bpf_timer_cb
  timer_cb1				  timer_cb2
    bpf_timer_cancel(timer_cb2)		    bpf_timer_cancel(timer_cb1)
      hrtimer_cancel			      hrtimer_cancel

In this case, both callbacks will continue waiting for each other to
finish synchronously, causing a lockup.

The proposed fix adds support for tracking in-flight cancellations
*begun by other timer callbacks* for a particular BPF timer.  Whenever
preparing to call hrtimer_cancel, a callback will increment the target
timer's counter, then inspect its in-flight cancellations, and if
non-zero, return -EDEADLK to avoid situations where the target timer's
callback is waiting for its completion.

This does mean that in cases where a callback is fired and cancelled, it
will be unable to cancel any timers in that execution. This can be
alleviated by maintaining the list of waiting callbacks in bpf_hrtimer
and searching through it to avoid interdependencies, but this may
introduce additional delays in bpf_timer_cancel, in addition to
requiring extra state at runtime which may need to be allocated or
reused from bpf_hrtimer storage. Moreover, extra synchronization is
needed to delete these elements from the list of waiting callbacks once
hrtimer_cancel has finished.

The second patch is for a deadlock situation similar to above in
bpf_timer_cancel_and_free, but also a UAF scenario that can occur if
timer is armed before entering it, if hrtimer_running check causes the
hrtimer_cancel call to be skipped.

As seen above, synchronous hrtimer_cancel would lead to deadlock (if
same callback tries to free its timer, or two timers free each other),
therefore we queue work onto the global workqueue to ensure outstanding
timers are cancelled before bpf_hrtimer state is freed.

Further details are in the patches.

If a TCP socket is using TCP_USER_TIMEOUT, and the other peer
retracted its window to zero, tcp_retransmit_timer() can
retransmit a packet every two jiffies (2 ms for HZ=1000),
for about 4 minutes after TCP_USER_TIMEOUT has 'expired'.

The fix is to make sure tcp_rtx_probe0_timed_out() takes
icsk->icsk_user_timeout into account.

Before blamed commit, the socket would not timeout after
icsk->icsk_user_timeout, but would use standard exponential
backoff for the retransmits.

Also worth noting that before commit e89688e ("net: tcp:

nft_chain_validate already performs loop detection because a cycle will
result in a call stack overflow (ctx->level >= NFT_JUMP_STACK_SIZE).

It also follows maps via ->validate callback in nft_lookup, so there
appears no reason to iterate the maps again.

nf_tables_check_loops() and all its helper functions can be removed.
This improves ruleset load time significantly, from 23s down to 12s.

This also fixes a crash bug. Old loop detection code can result in
unbounded recursion:

I can't see any actual reason to attempt to check for this from
nft_validate_register_store(), at this point the transaction is still in

For nf-next it might make sense to either remove it or make this depend

In udp_v[46]_early_demux() and sk_lookup(), we do not touch the refcount

Currently, SOCK_RCU_FREE is flagged for a bound socket after being put

The amount of TX space in the hardware buffer is tracked in the tx_space
variable. The initial value is currently only set during driver probing.

After closing the interface and reopening it the tx_space variable has
the last value it had before close. If it is smaller than the size of
the first send packet after reopeing the interface the queue will be
stopped. The queue is woken up after receiving a TX interrupt but this
will never happen since we did not send anything.

This commit moves the initialization of the tx_space variable to the
ks8851_net_open function right before starting the TX queue. Also query
the value from the hardware instead of using a hard coded value.

Only the SPI chip variant is affected by this issue because only this
driver variant actually depends on the tx_space variable in the xmit
function.

The ct may be dropped if a clash has been resolved but is still passed to
the tcf_ct_flow_table_process_conn function for further usage. This issue
can be fixed by retrieving ct from skb again after confirming conntrack.

…p_socket

When using a BPF program on kernel_connect(), the call can return -EPERM. This
causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing
the kernel to potentially freeze up.

Neil suggested:

  This will propagate -EPERM up into other layers which might not be ready
  to handle it. It might be safer to map EPERM to an error we would be more
  likely to expect from the network system - such as ECONNREFUSED or ENETDOWN.

ECONNREFUSED as error seems reasonable. For programs setting a different error
can be out of reach (see handling in 4fbac77) in particular on kernels
which do not have f10d059 ("bpf: Make BPF_PROG_RUN_ARRAY return -err
instead of allow boolean"), thus given that it is better to simply remap for
consistent behavior. UDP does handle EPERM in xs_udp_send_request().

These warnings are generated because the prologue comment for
crush_choose_indep() uses the kernel-doc prefix, but the actual
comment is a very brief description that is not in kernel-doc
format. Since this is a static function there is no need to fully
document the function, so replace the kernel-doc comment prefix with a
standard comment prefix to remove these warnings.

When putting an inode during extent map shrinking we're doing a standard
iput() but that may take a long time in case the inode is dirty and we are
doing the final iput that triggers eviction - the VFS will have to wait
for writeback before calling the btrfs evict callback (see
fs/inode.c:evict()).

This slows down the task running the shrinker which may have been
triggered while updating some tree for example, meaning locks are held
as well as an open transaction handle.

Also if the iput() ends up triggering eviction and the inode has no links
anymore, then we trigger item truncation which requires flushing delayed
items, space reservation to start a transaction and that may trigger the
space reclaim task and wait for it, resulting in deadlocks in case the
reclaim task needs for example to commit a transaction and the shrinker
is being triggered from a path holding a transaction handle.

Syzbot reported such a case with the following stack traces:

The extent map shrinker can be called in a variety of contexts where we
are under memory pressure, and of them is when a task is trying to
allocate memory. For this reason the shrinker is typically called with a
value of struct shrink_control::nr_to_scan that is much smaller than what
we return in the nr_cached_objects callback of struct super_operations
(fs/btrfs/super.c:btrfs_nr_cached_objects()), so that the shrinker does
not take a long time and cause high latencies. However we can still take
a lot of time in the shrinker even for a limited amount of nr_to_scan:

1) When traversing the red black tree that tracks open inodes in a root,
   as for example with millions of open inodes we get a deep tree which
   takes time searching for an inode;

2) Iterating over the extent map tree, which is a red black tree, of an
   inode when doing the rb_next() calls and when removing an extent map
   from the tree, since often that requires rebalancing the red black
   tree;

3) When trying to write lock an inode's extent map tree we may wait for a
   significant amount of time, because there's either another task about
   to do IO and searching for an extent map in the tree or inserting an
   extent map in the tree, and we can have thousands or even millions of
   extent maps for an inode. Furthermore, there can be concurrent calls
   to the shrinker so the lock might be busy simply because there is
   already another task shrinking extent maps for the same inode;

4) We often reschedule if we need to, which further increases latency.

So improve on this by stopping the extent map shrinking code whenever we
need to reschedule and make it skip an inode if we can't immediately lock
its extent map tree.

We store the progress (root and inode numbers) of the extent map shrinker
in fs_info without any synchronization but we can have multiple tasks
calling into the shrinker during memory allocations when there's enough
memory pressure for example.

This can result in a task A reading fs_info->extent_map_shrinker_last_ino
after another task B updates it, and task A reading
fs_info->extent_map_shrinker_last_root before task B updates it, making
task A see an odd state that isn't necessarily harmful but may make it
skip certain inode ranges or do more work than necessary by going over
the same inodes again. These unprotected accesses would also trigger
warnings from tools like KCSAN.

So add a lock to protect access to these progress fields.

ASoC: Fixes for v6.10

A few fairly small fixes for ASoC, there's a relatively large set of
hardening changes for the cs_dsp firmware file parsing and a couple of
other small device specific fixes.

blk_queue_max_segment_size() ensured:

	if (max_size < PAGE_SIZE)
		max_size = PAGE_SIZE;

whereas:

blk_validate_limits() makes it an error:

	if (WARN_ON_ONCE(lim->max_segment_size < PAGE_SIZE))
		return -EINVAL;

The change from one to the other, exposed sdhci which was setting maximum
segment size too low in some circumstances.

Fix the maximum segment size when it is too low.

   - After withdrawing a fscache_cache via FSCACHE_CACHE_IS_WITHDRAWN

   - Only increment the nr_dentry_negative counter for dentries that are

When user submits a rxfh set command without touching XFRM_SYM_XOR,
rxfh.input_xfrm is set to RXH_XFRM_NO_CHANGE, which is equal to 0xff.

Testing if (rxfh.input_xfrm & RXH_XFRM_SYM_XOR &&
	    !ops->cap_rss_sym_xor_supported)
		return -EOPNOTSUPP;

Will always be true on devices that don't set cap_rss_sym_xor_supported,
since rxfh.input_xfrm & RXH_XFRM_SYM_XOR is always true, if input_xfrm
was not set, i.e RXH_XFRM_NO_CHANGE=0xff, which will result in failure
of any command that doesn't require any change of XFRM, e.g RSS context
or hash function changes.

To avoid this breakage, test if rxfh.input_xfrm != RXH_XFRM_NO_CHANGE
before testing other conditions. Note that the problem will only trigger
with XFRM-aware userspace, old ethtool CLI would continue to work.

Remove wrong EIO to EGAIN conversion and pass all errors as is.

After commit 230f3d5 ("i40e: remove i40e_status"), which should only
replace F/W specific error codes with Linux kernel generic, all EIO errors
suddenly started to be converted into EAGAIN which leads nvmupdate to retry
until it timeouts and sometimes fails after more than 20 minutes in the
middle of NVM update, so NVM becomes corrupted.

The bug affects users only at the time when they try to update NVM, and
only F/W versions that generate errors while nvmupdate. For example, X710DA2
with 0x8000ECB7 F/W is affected, but there are probably more...

Command for reproduction is just NVM update:
 ./nvmupdate64

In the log instead of:
 i40e_nvmupd_exec_aq err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENOMEM)
appears:
 i40e_nvmupd_exec_aq err -EIO aq_err I40E_AQ_RC_ENOMEM
 i40e: eeprom check failed (-5), Tx/Rx traffic disabled

The problematic code did silently convert EIO into EAGAIN which forced
nvmupdate to ignore EAGAIN error and retry the same operation until timeout.
That's why NVM update takes 20+ minutes to finish with the fail in the end.

There are many generations of omaps to maintain, and I will be only active
as a hobbyist with time permitting. Let's add more maintainers to ensure
continued Linux support.

TI is interested in maintaining the active SoCs such as am3, am4 and
dra7. And the hobbyists are interested in maintaining some of the older
devices, mainly based on omap3 and 4 SoCs.

Kevin and Roger have agreed to maintain the active TI parts. Both Kevin
and Roger have been working on the omap variants for a long time, and
have a good understanding of the hardware.

Aaro and Andreas have agreed to maintain the community devices. Both Aaro
and Andreas have long experience on working with the earlier TI SoCs.

While at it, let's also change me to be a reviewer for the omap1, and
drop the link to my old omap web page.

 "Fix a regression in extent map shrinker behaviour.

  In the past weeks we got reports from users that there are huge

  of extent maps (it was added to fix a build up of the structures in
  memory).

  I'm assuming that the freezes would happen to many users after release
  so I'd like to get it merged now so it's in 6.10. Although the diff
  size is not small the changes are relatively straightforward, the
  reporters verified the fixes and we did testing on our side.

  The fixes:

   - adjust behaviour under memory pressure and check lock or scheduling
     conditions, bail out if needed

   - synchronize tracking of the scanning progress so inode ranges are
     not skipped or work duplicated

   - do a delayed iput when scanning a root so evicting an inode does
     not slow things down in case of lots of dirty data, also fix
     lockdep warning, a deadlock could happen when writing the dirty
     data would need to start a transaction"

…inux/kernel/git/andi.shyti/linux into i2c/for-current

This tag includes three fixes for the Renesas R-Car driver:

 1. Ensures the device is in a known state after probing.
 2. Allows clearing the NO_RXDMA flag after a reset.
 3. Forces a reset before any transfer on Gen3+ platforms to
    prevent disruption of the configuration during parallel
    transfers.

If you try to set /proc/fs/cifs/SecurityFlags to 1 it
will set them to CIFSSEC_MUST_NTLMV2 which no longer is
relevant (the less secure ones like lanman have been removed
from cifs.ko) and is also missing some flags (like for
signing and encryption) and can even cause mount to fail,
so change this to set it to Kerberos in this case.

Also change the description of the SecurityFlags to remove mention
of flags which are no longer supported.

Pull scheduler fixes from Borislav Petkov:

 - Fix a performance regression when measuring the CPU time of a thread
   (clock_gettime(CLOCK_THREAD_CPUTIME_ID,...)) due to the addition of
   PSI IRQ time accounting in the hotpath

 - Fix a task_struct leak due to missing to decrement the refcount when
   the task is enqueued before the timer which is supposed to do that,
   expires

 - Revert an attempt to expedite detaching of movable tasks, as finding
   those could become very costly. Turns out the original issue wasn't
   even hit by anyone

After [1] in upstream LLVM, ld.lld's version output became slightly
different when the cmake configuration option LLVM_APPEND_VC_REV is
disabled.

Before:

  Debian LLD 19.0.0 (compatible with GNU linkers)

After:

  Debian LLD 19.0.0, compatible with GNU linkers

This results in ld-version.sh failing with

  scripts/ld-version.sh: 18: arithmetic expression: expecting EOF: "10000 * 19 + 100 * 0 + 0,"

because the trailing comma is included in the patch level part of the
expression. While [1] has been partially reverted in [2] to avoid this
breakage (as it impacts the configuration stage and it is present in all
LTS branches), it would be good to make ld-version.sh more robust
against such miniscule changes like this one.

Use POSIX shell parameter expansion [3] to remove the largest suffix
after just numbers and periods, replacing of the current removal of
everything after a hyphen. ld-version.sh continues to work for a number
of distributions (Arch Linux, Debian, and Fedora) and the kernel.org
toolchains and no longer errors on a version of ld.lld with [1].

After 8d1001f (kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n),
the following warning "warning: File listed twice: *.dtb" is appearing for
every dtb file that is included.
The reason is that the commented commit already adds the folder
/lib/modules/%{KERNELRELEASE} in kernel.list file so the folder
/lib/modules/%{KERNELRELEASE}/dtb is no longer necessary, just remove it.

When a software KASAN mode is enabled, the fortify tests emit warnings
on some architectures.

For example, for ARCH=arm, the combination of CONFIG_FORTIFY_SOURCE=y
and CONFIG_KASAN=y produces the following warnings:

    TEST    lib/test_fortify/read_overflow-memchr.log
  warning: unsafe memchr() usage lacked '__read_overflow' warning in lib/test_fortify/read_overflow-memchr.c
    TEST    lib/test_fortify/read_overflow-memchr_inv.log
  warning: unsafe memchr_inv() usage lacked '__read_overflow' symbol in lib/test_fortify/read_overflow-memchr_inv.c
    TEST    lib/test_fortify/read_overflow-memcmp.log
  warning: unsafe memcmp() usage lacked '__read_overflow' warning in lib/test_fortify/read_overflow-memcmp.c
    TEST    lib/test_fortify/read_overflow-memscan.log
  warning: unsafe memscan() usage lacked '__read_overflow' symbol in lib/test_fortify/read_overflow-memscan.c
    TEST    lib/test_fortify/read_overflow2-memcmp.log
  warning: unsafe memcmp() usage lacked '__read_overflow2' warning in lib/test_fortify/read_overflow2-memcmp.c
     [ more and more similar warnings... ]

Commit 9c2d132 ("kbuild: provide reasonable defaults for tool
coverage") removed KASAN flags from non-kernel objects by default.
It was an intended behavior because lib/test_fortify/*.c are unit
tests that are not linked to the kernel.

As it turns out, some architectures require -fsanitize=kernel-(hw)address
to define __SANITIZE_ADDRESS__ for the fortify tests.

Without __SANITIZE_ADDRESS__ defined, arch/arm/include/asm/string.h
defines __NO_FORTIFY, thus excluding <linux/fortify-string.h>.

This issue does not occur on x86 thanks to commit 4ec4190
("kasan, x86: don't rename memintrinsics in uninstrumented files"),
but there are still some architectures that define __NO_FORTIFY
in such a situation.

Set KASAN_SANITIZE=y explicitly to the fortify tests.

Commit 3a93da2 ("power: supply: rt5033: Use devm_power_supply_register() helper")
reworked the driver to use devm. While at it, the i2c_set_clientdata
was dropped along with the remove callback. Unfortunately other parts
of the driver also rely on i2c clientdata so this causes kernel oops.

Bring the call back to fix the driver.
