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.

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:
BUG: TASK stack guard page was hit at ....
Oops: stack guard page: 0000 [#1] PREEMPT SMP KASAN

with a suitable ruleset during validation of register stores.
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
progress, so we don't have a full picture of the rule graph.
For nf-next it might make sense to either remove it or make this depend
on table->validate_state in case we could catch an error earlier
(for improved error reporting to userspace).

we hit a condition where both run in parallel and cancel each other.

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 e89688e3e9 ("net: tcp:

would last 2 minutes instead of 4.

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.

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.

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.

The order of parameters can be traced back all the way to 6ac99e8f23
("bpf: Introduce bpf sk local storage") accross several refactorings,
and that's why the commit is used as a Fixes: tag.
In v6.10-rc1, a different commit 2c321f3f70 ("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 2c321f3f70 is present
- CONFIG_MEMCG is not enabled in .config
- CONFIG_WERROR turns this from a compiler warning to error

Pull VFIO fix from Alex Williamson:
- Recent stable backports are exposing a bug introduced in the v6.10
development cycle where a counter value is uninitialized. This leads
to regressions in userspace drivers like QEMU where where the kernel
might ask for an arbitrary buffer size or return out of memory itself
based on a bogus value. Zero initialize the counter. (Yi Liu)

Pull thermal control fixes from Rafael Wysocki:
"These fix a possible NULL pointer dereference in a thermal governor,
fix up the handling of thermal zones enabled before their temperature
can be determined and fix list sorting during thermal zone temperature
updates.
Specifics:
- Prevent the Power Allocator thermal governor from dereferencing a
NULL pointer if it is bound to a tripless thermal zone (Nícolas
Prado)
- Prevent thermal zones enabled too early from staying effectively
dormant forever because their temperature cannot be determined
initially (Rafael Wysocki)
- Fix list sorting during thermal zone temperature updates to ensure
the proper ordering of trip crossing notifications (Rafael
Wysocki)"
