When two threads run proc_do_sync_threshold() in parallel,
data races could happen between the two memcpy():
Thread-1 Thread-2
memcpy(val, valp, sizeof(val));
memcpy(valp, val, sizeof(val));
This race might mess up the (struct ctl_table *) table->data,
so we add a mutex lock to serialize them.

In SCTP protocol, it is using the same timer (T2 timer) for SHUTDOWN and
SHUTDOWN_ACK retransmission. However in sctp conntrack the default timeout
value for SCTP_CONNTRACK_SHUTDOWN_ACK_SENT state is 3 secs while it's 300
msecs for SCTP_CONNTRACK_SHUTDOWN_SEND/RECV state.
As Paolo Valerio noticed, this might cause unwanted expiration of the ct
entry. In my test, with 1s tc netem delay set on the NAT path, after the
SHUTDOWN is sent, the sctp ct entry enters SCTP_CONNTRACK_SHUTDOWN_SEND
state. However, due to 300ms (too short) delay, when the SHUTDOWN_ACK is
sent back from the peer, the sctp ct entry has expired and been deleted,
and then the SHUTDOWN_ACK has to be dropped.
Also, it is confusing these two sysctl options always show 0 due to all
timeout values using sec as unit:
net.netfilter.nf_conntrack_sctp_timeout_shutdown_recd = 0
net.netfilter.nf_conntrack_sctp_timeout_shutdown_sent = 0
This patch fixes it by also using 3 secs for sctp shutdown send and recv
state in sctp conntrack, which is also RTO.initial value in SCTP protocol.
Note that the very short time value for SCTP_CONNTRACK_SHUTDOWN_SEND/RECV
was probably used for a rare scenario where SHUTDOWN is sent on 1st path
but SHUTDOWN_ACK is replied on 2nd path, then a new connection started
immediately on 1st path. So this patch also moves from SHUTDOWN_SEND/RECV
to CLOSE when receiving INIT in the ORIGINAL direction.

nftables selftests fail:
run-tests.sh testcases/sets/0044interval_overlap_0
Expected: 0-2 . 0-3, got:
W: [FAILED] ./testcases/sets/0044interval_overlap_0: got 1
Insertion must ignore duplicate but expired entries.
Moreover, there is a strange asymmetry in nft_pipapo_activate:
It refetches the current element, whereas the other ->activate callbacks
(bitmap, hash, rhash, rbtree) use elem->priv.
Same for .remove: other set implementations take elem->priv,
nft_pipapo_remove fetches elem->priv, then does a relookup,
remove this.
I suspect this was the reason for the change that prompted the
removal of the expired check in pipapo_get() in the first place,
but skipping exired elements there makes no sense to me, this helper
is used for normal get requests, insertions (duplicate check)
and deactivate callback.
In first two cases expired elements must be skipped.
For ->deactivate(), this gets called for DELSETELEM, so it
seems to me that expired elements should be skipped as well, i.e.
delete request should fail with -ENOENT error.

In the real workload, I encountered an issue which could cause the RTO
timer to retransmit the skb per 1ms with linear option enabled. The amount
of lost-retransmitted skbs can go up to 1000+ instantly.
The root cause is that if the icsk_rto happens to be zero in the 6th round
(which is the TCP_THIN_LINEAR_RETRIES value), then it will always be zero
due to the changed calculation method in tcp_retransmit_timer() as follows:
icsk->icsk_rto = min(icsk->icsk_rto << 1, TCP_RTO_MAX);
Above line could be converted to
icsk->icsk_rto = min(0 << 1, TCP_RTO_MAX) = 0
Therefore, the timer expires so quickly without any doubt.
I read through the RFC 6298 and found that the RTO value can be rounded
up to a certain value, in Linux, say TCP_RTO_MIN as default, which is
regarded as the lower bound in this patch as suggested by Eric.

r5l_flush_stripe_to_raid() will check if the list 'flushing_ios' is

Use tabs/spaces consistently: hard tabs for marking recipe lines only,
spaces for everything else.
Also, the OPTFLAGS declaration actually included the tabs preceding the
line comment, making compiler invocation lines unnecessarily long. As
the entire block of declarations are meant for ad-hoc customization
(otherwise they would probably make use of `?=` instead of `=`), move
the "Adjust as desired" comment above the block too to fix the long

After commit b39f35ebe86d ("md: don't quiesce in mddev_suspend()"),
'conf->barrier' will be leaked in the case that raid10 takeover raid0:
level_store
pers->takeover -> raid10_takeover
raid10_takeover_raid0
WRITE_ONCE(conf->barrier, 1)
mddev_suspend
// still raid0
mddev->pers = pers
// switch to raid10
mddev_resume
// resume without suspend
After the above commit, mddev_resume() will not decrease 'conf->barrier'
that is set in raid10_takeover_raid0().
Fix this problem by not setting 'conf->barrier' in raid10_takeover_raid0().
By the way, this problem is found while I'm trying to make
mddev_suspend/resume() to be independent from raid personalities. raid10
is the only personality to use reference count in the quiesce() callback
and this problem is only related to raid10.

The encode_dma() function has some validation on in_trans->size but it
would be more clear to move those checks to find_and_map_user_pages().
The encode_dma() had two checks:
if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size)
return -EINVAL;
The in_trans->addr variable is the starting address. The in_trans->size
variable is the total size of the transfer. The transfer can occur in
parts and the resources->xferred_dma_size tracks how many bytes we have
already transferred.
This patch introduces a new variable "remaining" which represents the
amount we want to transfer (in_trans->size) minus the amount we have
already transferred (resources->xferred_dma_size).
I have modified the check for if in_trans->size is zero to instead check
if in_trans->size is less than resources->xferred_dma_size. If we have
already transferred more bytes than in_trans->size then there are negative
bytes remaining which doesn't make sense. If there are zero bytes
remaining to be copied, just return success.
The check in encode_dma() checked that "addr + size" could not overflow
and barring a driver bug that should work, but it's easier to check if
we do this in parts. First check that "in_trans->addr +
resources->xferred_dma_size" is safe. Then check that "xfer_start_addr +
remaining" is safe.
My final concern was that we are dealing with u64 values but on 32bit
systems the kmalloc() function will truncate the sizes to 32 bits. So
I calculated "total = in_trans->size + offset_in_page(xfer_start_addr);"
and returned -EINVAL if it were >= SIZE_MAX. This will not affect 64bit
systems.

The failure handling procedure destroys page pools for all queues,
including those that haven't had their page pool created yet. this patch
introduces necessary adjustments to prevent potential risks and
inconsistency with the error handling behavior.

====================
octeon_ep: fixes for error and remove paths
I have an Octeon card that's misconfigured in a way that exposes a
couple of bugs in the octeon_ep driver's error paths. It can reproduce
the issues that patches 1 & 4 are fixing. Patches 2 & 3 are a result of
reviewing the nearby code.

If it fails to get the devices's MAC address, octep_probe exits while
leaving the delayed work intr_poll_task queued. When the work later
runs, it's a use after free.
Move the cancelation of intr_poll_task from octep_remove into
octep_device_cleanup. This does not change anything in the octep_remove
flow, but octep_device_cleanup is called also in the octep_probe error
path, where the cancelation is needed.
Note that the cancelation of ctrl_mbox_task has to follow
intr_poll_task's, because the ctrl_mbox_task may be queued by
intr_poll_task.

intr_poll_task may queue ctrl_mbox_task. The function
octep_poll_non_ioq_interrupts_cn93_pf does this.
When removing the driver and canceling these two works, cancel
ctrl_mbox_task last to guarantee it does not run anymore.

tx_timeout_task is canceled too early when removing the driver. Nothing
prevents .ndo_tx_timeout from triggering and queuing the work again.
Better cancel it after the netdev is unregistered.
It's harmless for octep_tx_timeout_task to run in the window between the
unregistration and cancelation, because it checks netif_running.

The intention was to wait up to 500 ms for the mbox response.
The third argument to wait_event_interruptible_timeout() is supposed to
be the timeout duration. The driver mistakenly passed absolute time
instead.

On Zynq UltraScale+ MPSoC ubuntu platform when systemctl issues suspend,
network manager bring down the interface and goes into suspend. When it
wakes up it again enables the interface.
This leads to xilinx-psgtr "PLL lock timeout" on interface bringup, as
the power management controller power down the entire FPD (including
SERDES) if none of the FPD devices are in use and serdes is not
initialized on resume.
$ sudo rtcwake -m no -s 120 -v
$ sudo systemctl suspend <this does ifconfig eth1 down>
$ ifconfig eth1 up
xilinx-psgtr fd400000.phy: lane 0 (type 10, protocol 5): PLL lock timeout
phy phy-fd400000.phy.0: phy poweron failed --> -110
macb driver is called in this way:
1. macb_close: Stop network interface. In this function, it
reset MACB IP and disables PHY and network interface.
2. macb_suspend: It is called in kernel suspend flow. But because
network interface has been disabled(netif_running(ndev) is
false), it does nothing and returns directly;
3. System goes into suspend state. Some time later, system is
waken up by RTC wakeup device;
4. macb_resume: It does nothing because network interface has
been disabled;
5. macb_open: It is called to enable network interface again. ethernet
interface is initialized in this API but serdes which is power-off
by PMUFW during FPD-off suspend is not initialized again and so
we hit GT PLL lock issue on open.
To resolve this PLL timeout issue always do PS GTR initialization
when ethernet device is configured as non-wakeup source.

bio_iov_iter_get_pages() trims the IO based on the block size of the
block device the IO will be issued to.
However, bcachefs is a multi device filesystem; when we're creating the
bio we don't yet know which block device the bio will be submitted to -
we have to handle the alignment checks elsewhere.
Thus this is needed to avoid a null ptr deref.

iproc_i2c_rd_reg() and iproc_i2c_wr_reg() are called from both
interrupt context (e.g. bcm_iproc_i2c_isr) and process context
(e.g. bcm_iproc_i2c_suspend). Therefore, interrupts should be
disabled to avoid potential deadlock. To prevent this scenario,
use spin_lock_irqsave().

The current display probe is unable to differentiate between IVB Q and
IVB D GT2 server, as they both have the same device id, but different
subvendor and subdevice. This leads to the latter being misidentified as
the former, and should just end up not having a display. However, the no
display case returns a NULL as the display device info, and promptly
oopses.
As the IVB Q case is rare, and we're anyway moving towards GMD ID,
handle the identification requiring subvendor and subdevice as a special
case first, instead of unnecessarily growing the intel_display_ids[]
array with subvendor and subdevice.

Commit 3f9ffce5765d ("drm/i915: Do panel VBT init early if the VBT
declares an explicit panel type") started using -1 as the value for
unset panel_type. It gets initialized in intel_panel_init_alloc(), but
the SDVO code never calls it.
Call intel_panel_init_alloc() to initialize the panel, including the
panel_type.
