In case of SMBUS byte read with PEC enabled, the whole transfer
is split into two commands. A first write command, followed by
a read command. The write command does not have any PEC byte
and a PEC byte is appended at the end of the read command.
(cf Read byte protocol with PEC in SMBUS specification)
Within the STM32 I2C controller, handling (either sending
or receiving) of the PEC byte is done via the PECBYTE bit in
register CR2.
Currently, the PECBYTE is set at the beginning of a transfer,
which lead to sending a PEC byte at the end of the write command
(hence losing the real last byte), and also does not check the
PEC byte received during the read command.
This patch corrects the function stm32f7_i2c_smbus_xfer_msg
in order to only set the PECBYTE during the read command.

the maximum number of tx and rx queues. When the user changes the
tx queues to single queue, the MAC should be capable of supporting Half

The fpga core currently assumes that all manager, bridge, and region
devices have a parent device associated with a driver that can be used
to take the module's refcount. This behavior causes the fpga test suites
to crash with a null-ptr-deref since parent fake devices do not have a
driver. This patch disables all fpga KUnit test suites when loadable
module support is enabled until the fpga core is fixed. Test suites
can still be run using the KUnit default UML kernel.

When a programming status desc is encountered on the rx_ring,
next_to_process is bumped along with cleaned_count but next_to_clean is
not. This causes I40E_DESC_UNUSED() macro to misbehave resulting in
overwriting whole ring with new buffers.
Update next_to_clean to point to next_to_process on seeing a programming
status desc if not in the middle of handling a multi-frag packet. Also,
bump cleaned_count only for such case as otherwise next_to_clean buffer

Under memory stress conditions, tcp_sendmsg_locked()
might call sk_stream_wait_memory(), thus releasing the socket lock.
If a fresh skb has been allocated prior to this,
we should not leave it in the write queue otherwise
tcp_write_xmit() could panic.
This apparently does not happen often, but a future change
in __sk_mem_raise_allocated() that Shakeel and others are
considering would increase chances of being hurt.
Under discussion is to remove this controversial part:
/* Fail only if socket is _under_ its sndbuf.
* In this case we cannot block, so that we have to fail.
*/
if (sk->sk_wmem_queued + size >= sk->sk_sndbuf) {
/* Force charge with __GFP_NOFAIL */
if (memcg_charge && !charged) {
mem_cgroup_charge_skmem(sk->sk_memcg, amt,
gfp_memcg_charge() | __GFP_NOFAIL);
}
return 1;
}

Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.
The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.
To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.
A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.
Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.
Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.
The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

When a kprobe is attached to a function that's name is not unique (is
static and shares the name with other functions in the kernel), the
kprobe is attached to the first function it finds. This is a bug as the
function that it is attaching to is not necessarily the one that the
user wants to attach to.
Instead of blindly picking a function to attach to what is ambiguous,
error with EADDRNOTAVAIL to let the user know that this function is not
unique, and that the user must use another unique function with an
address offset to get to the function they want to attach to.

It is not safe to initialize the waitqueues after queueing the

The chance of this causing a real problem is very small, because
there will be some sleeping before any of the waitqueues get used.
I got a crash only after inserting an artificial sleep in iavf_probe.
Queue the watchdog_task as the last step in iavf_probe. Add a comment to
prevent repeating the mistake.

==================================================================
The write side of drivers/net/ethernet/realtek/r8169_main.c is:
==================
4251 /* rtl_tx needs to see descriptor changes before updated tp->cur_tx */
4252 smp_wmb();
4253
→ 4254 WRITE_ONCE(tp->cur_tx, tp->cur_tx + frags + 1);
4255
4256 stop_queue = !netif_subqueue_maybe_stop(dev, 0, rtl_tx_slots_avail(tp),
4257 R8169_TX_STOP_THRS,
4258 R8169_TX_START_THRS);
The read side is the function rtl_tx():
4355 static void rtl_tx(struct net_device *dev, struct rtl8169_private *tp,
4356 int budget)
4357 {
4358 unsigned int dirty_tx, bytes_compl = 0, pkts_compl = 0;
4359 struct sk_buff *skb;
4360
4361 dirty_tx = tp->dirty_tx;
4362
4363 while (READ_ONCE(tp->cur_tx) != dirty_tx) {
4364 unsigned int entry = dirty_tx % NUM_TX_DESC;
4365 u32 status;
4366
4367 status = le32_to_cpu(tp->TxDescArray[entry].opts1);
4368 if (status & DescOwn)
4369 break;
4370
4371 skb = tp->tx_skb[entry].skb;
4372 rtl8169_unmap_tx_skb(tp, entry);
4373
4374 if (skb) {
4375 pkts_compl++;
4376 bytes_compl += skb->len;
4377 napi_consume_skb(skb, budget);
4378 }
4379 dirty_tx++;
4380 }
4381
4382 if (tp->dirty_tx != dirty_tx) {
4383 dev_sw_netstats_tx_add(dev, pkts_compl, bytes_compl);
4384 WRITE_ONCE(tp->dirty_tx, dirty_tx);
4385
4386 netif_subqueue_completed_wake(dev, 0, pkts_compl, bytes_compl,
4387 rtl_tx_slots_avail(tp),
4388 R8169_TX_START_THRS);
4389 /*
4390 * 8168 hack: TxPoll requests are lost when the Tx packets are
4391 * too close. Let's kick an extra TxPoll request when a burst
4392 * of start_xmit activity is detected (if it is not detected,
4393 * it is slow enough). -- FR
4394 * If skb is NULL then we come here again once a tx irq is

4396 */
→ 4397 if (tp->cur_tx != dirty_tx && skb)
4398 rtl8169_doorbell(tp);
4399 }
4400 }
Obviously from the code, an earlier detected data-race for tp->cur_tx was fixed in the
line 4363:
4363 while (READ_ONCE(tp->cur_tx) != dirty_tx) {
but the same solution is required for protecting the other access to tp->cur_tx:
→ 4397 if (READ_ONCE(tp->cur_tx) != dirty_tx && skb)
4398 rtl8169_doorbell(tp);
The write in the line 4254 is protected with WRITE_ONCE(), but the read in the line 4397
might have suffered read tearing under some compiler optimisations.
The fix eliminated the KCSAN data-race report for this bug.
It is yet to be evaluated what happens if tp->cur_tx changes between the test in line 4363
and line 4397. This test should certainly not be cached by the compiler in some register
for such a long time, while asynchronous writes to tp->cur_tx might have occurred in line
4254 in the meantime.
