In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally reading across neighboring array fields.
Add a wrapping struct to serve as the memcpy() source so the compiler
can perform appropriate bounds checking, avoiding this future warning:
In function '__fortify_memcpy',

Commit 5d1b1b3f492f ("ext4: fix BUG when calling ext4_error with locked
block group") introduces ext4_grp_locked_error to handle unlocking a
group in error cases. Otherwise, there is a possibility of a sleep while
atomic. However, since 43c73221b3b1 ("ext4: replace BUG_ON with WARN_ON

call while a group spinlock is held. Replace this with
ext4_grp_locked_error.

Pull clk updates from Stephen Boyd:
"This round has a diffstat dominated by Qualcomm clk drivers. Honestly
though that's just a bunch of data so the diffstat reflects that.
Looking beyond that there's just a bunch of updates all around in
various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors
that have a lot of patches in here.
Overall the driver changes look to be mostly enabling more clks and
non-critical fixes that we could hold until the next merge window.
I'm especially excited about the series from Arnd that graduates
clkdev to be the only implementation of clk_get() and clk_put().
That's a good step in the right direction to migreate eveerything over
to the common clk framework. Now we don't have to worry about clkdev
specific details, they're just part of the clk API now.
Core:
- clkdev is now the only option, i.e. clk_get()/clk_put() is
implemented in only one place in the kernel instead of in
drivers/clk/clkdev.c and in architectures that want their own
implementation
New Drivers:
- Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant
Clock Jitter Cleaner With Dual Loop PLLs
- Qualcomm MDM9607 GCC
- Qualcomm SC8180X display clks
- Qualcomm SM6125 GCC
- Qualcomm SM8250 CAMCC (camera)

The MPTCP receive path is hooked only into the TCP slow-path.
The DSS presence allows plain MPTCP traffic to hit that
consistently.
Since commit e1ff9e82e2ea ("net: mptcp: improve fallback to TCP"),
when an MPTCP socket falls back to TCP, it can hit the TCP receive
fast-path, and delay or stop triggering the event notification.
Address the issue explicitly disabling the header prediction
for MPTCP sockets.

Normally, if a reset fails due to failover or other communication error
there is another reset (eg: FAILOVER) in the queue and we would process
that reset. But if we are unable to communicate with PHYP or VIOS after
H_FREE_CRQ, there would be no other resets in the queue and the adapter
would be in an undefined state even though it was in the OPEN state
earlier. While starting the reset we set the carrier to off state so
we won't even get the timeout resets.
If the last queued reset fails, retry it as a hard reset (after the
usual 60 second settling time).

====================
ptp: support virtual clocks and timestamping
Current PTP driver exposes one PTP device to user which binds network
interface/interfaces to provide timestamping. Actually we have a way
utilizing timecounter/cyclecounter to virtualize any number of PTP
clocks based on a same free running physical clock for using.
The purpose of having multiple PTP virtual clocks is for user space
to directly/easily use them for multiple domains synchronization.
user
space: ^ ^
| SO_TIMESTAMPING new flag: | Packets with
| SOF_TIMESTAMPING_BIND_PHC | TX/RX HW timestamps

pclock: | ptp0 free running |
+--------------------------------------------+
The block diagram may explain how it works. Besides the PTP virtual
clocks, the packet HW timestamp converting to the bound PHC is also
done in sock driver. For user space, PTP virtual clocks can be
created via sysfs, and extended SO_TIMESTAMPING API (new flag
SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock
for timestamping.
The test tool timestamping.c (together with linuxptp phc_ctl tool) can
be used to verify:

SOF_TIMESTAMPING_BIND_PHC. When PTP virtual clocks are

- Setting the value can create corresponding number of ptp

Hariprasad Kelam says:
====================
DMAC based packet filtering
Each MAC block supports 32 DMAC filters which can be configured to accept
or drop packets based on address match This patch series adds mbox
handlers and extends ntuple filter callbacks to accomdate DMAC filters
such that user can install DMAC based filters on interface from ethtool.
Patch1 adds necessary mbox handlers such that mbox consumers like PF netdev
can add/delete/update DMAC filters and Patch2 adds debugfs support to dump
current list of installed filters. Patch3 adds support to call mbox
handlers upon receiving DMAC filters from ethtool ntuple commands.
Change-log:
v2 -
- fixed indentation issues.
v3 -
- fixed kdoc warnings

DMAC filtering can be achieved by either NPC MCAM rules or
CGX/RPM MAC filters. Currently we are achieving this by NPC
MCAM rules. This patch offloads DMAC filters to CGX/RPM MAC
filters instead of NPC MCAM rules. Offloading DMAC filter to
CGX/RPM block helps in reducing traffic to NPC block and
save MCAM rules

MAC block supports 32 dmac filters which are logically
divided among all attached LMACS.
For example MAC block0 having one LMAC then maximum supported
filters are 32 where as MAC block1 having 4 enabled LMACS
them maximum supported filteres are 8 for each LMAC.
This patch adds mbox handlers to add/delete/update mac entry
in DMAC filter table.

If one entered io_req_task_work_add() not seeing PF_EXITING, it will set
a ->task_state bit and try task_work_add(), which may fail by that
moment. If that happens the function would try to cancel the request.
However, in a meanwhile there might come other io_req_task_work_add()
callers, which will see the bit set and leave their requests in the
list, which will never be executed.
Don't propagate an error, but clear the bit first and then fallback
all requests that we can splice from the list. The callback functions
have to be able to deal with PF_EXITING, so poll and apoll was modified
via changing io_poll_rewait().

Since we don't really use req->task_work anymore, get rid of it together
with the nasty ->func aliasing between ->io_task_work and ->task_work,
and hide ->fallback_node inside of io_task_work.
Also, as task_work is gone now, replace the callback type from
task_work_func_t to a function taking io_kiocb to avoid casting and
simplify code.

When task_work_add() fails, we use ->exit_task_work to queue the work.
That will be run only in the cancellation path, which happens either
when the ctx is dying or one of tasks with inflight requests is exiting
or executing. There is a good chance that such a request would just get
stuck in the list potentially hodling a file, all io_uring rsrc
recycling or some other resources. Nothing terrible, it'll go away at
some point, but we don't want to lock them up for longer than needed.
Replace that hand made ->exit_task_work with delayed_work + llist
inspired by fput_many().

ASan reports a memory leak caused by evlist not being deleted on exit in
perf-report, perf-script and perf-data.
The problem is caused by evlist->session not being deleted, which is
allocated in perf_session__read_header, called in perf_session__new if
perf_data is in read mode.
In case of write mode, the session->evlist is filled by the caller.
This patch solves the problem by calling evlist__delete in
perf_session__delete if perf_data is in read mode.
Changes in v2:
- call evlist__delete from within perf_session__delete
v1: https://lore.kernel.org/lkml/20210621234317.235545-1-rickyman7@gmail.com/

In perf annotate, when 's' is pressed on a line containing source code,
it shows the message "Only available for assembly lines".
This patch gets rid of the error, moving the cursr to the next available
asm line (or the closest previous one if no asm line is found moving
forwards), before hiding source code lines.
Changes in v2:
- handle case of no asm line found in
annotate_browser__find_next_asm_line by returning NULL and
handling error in caller.
