Rather than using svc_get() and svc_put() to hold a stable reference to
the nfsd_svc for netlink lookups, simply hold the mutex for the entire
time.
The "entire" time isn't very long, and the mutex is not often contented.
This makes way for us to remove the refcounts of svc, which is more
confusing than useful.

If write_ports_addfd or write_ports_addxprt fail, they call nfsd_put()
without calling nfsd_last_thread(). This leaves nn->nfsd_serv pointing
to a structure that has been freed.
So remove 'static' from nfsd_last_thread() and call it when the
nfsd_serv is about to be destroyed.

As the ring buffer recording requires cmpxchg() to work, if the
architecture does not support cmpxchg in NMI, then do not do any recording
within an NMI.

The rb_time_cmpxchg() on 32-bit architectures requires setting three
32-bit words to represent the 64-bit timestamp, with some salt for
synchronization. Those are: msb, top, and bottom
The issue is, the rb_time_cmpxchg() did not properly salt the msb portion,
and the msb that was written was stale.

The following race can cause rb_time_read() to observe a corrupted time
stamp:
rb_time_cmpxchg()
[...]
if (!rb_time_read_cmpxchg(&t->msb, msb, msb2))
return false;
if (!rb_time_read_cmpxchg(&t->top, top, top2))
return false;
<interrupted before updating bottom>
__rb_time_read()
[...]
do {
c = local_read(&t->cnt);
top = local_read(&t->top);
bottom = local_read(&t->bottom);
msb = local_read(&t->msb);
} while (c != local_read(&t->cnt));
*cnt = rb_time_cnt(top);
/* If top and msb counts don't match, this interrupted a write */
if (*cnt != rb_time_cnt(msb))
return false;
^ this check fails to catch that "bottom" is still not updated.
So the old "bottom" value is returned, which is wrong.
Fix this by checking that all three of msb, top, and bottom 2-bit cnt
values match.
The reason to favor checking all three fields over requiring a specific
update order for both rb_time_set() and rb_time_cmpxchg() is because
checking all three fields is more robust to handle partial failures of
rb_time_cmpxchg() when interrupted by nested rb_time_set().

Mathieu Desnoyers pointed out an issue in the rb_time_cmpxchg() for 32 bit
architectures. That is:
static bool rb_time_cmpxchg(rb_time_t *t, u64 expect, u64 set)
{
unsigned long cnt, top, bottom, msb;
unsigned long cnt2, top2, bottom2, msb2;
u64 val;
/* The cmpxchg always fails if it interrupted an update */
if (!__rb_time_read(t, &val, &cnt2))
return false;
if (val != expect)
return false;
<<<< interrupted here!
cnt = local_read(&t->cnt);
The problem is that the synchronization counter in the rb_time_t is read
*after* the value of the timestamp is read. That means if an interrupt
were to come in between the value being read and the counter being read,
it can change the value and the counter and the interrupted process would
be clueless about it!
The counter needs to be read first and then the value. That way it is easy
to tell if the value is stale or not. If the counter hasn't been updated,
then the value is still good.

When filtering is enabled, a temporary buffer is created to place the
content of the trace event output so that the filter logic can decide
from the trace event output if the trace event should be filtered out or
not. If it is to be filtered out, the content in the temporary buffer is
simply discarded, otherwise it is written into the trace buffer.
But if an interrupt were to come in while a previous event was using that
temporary buffer, the event written by the interrupt would actually go
into the ring buffer itself to prevent corrupting the data on the
temporary buffer. If the event is to be filtered out, the event in the
ring buffer is discarded, or if it fails to discard because another event
were to have already come in, it is turned into padding.
The update to the write_stamp in the rb_try_to_discard() happens after a
fix was made to force the next event after the discard to use an absolute
timestamp by setting the before_stamp to zero so it does not match the
write_stamp (which causes an event to use the absolute timestamp).
But there's an effort in rb_try_to_discard() to put back the write_stamp
to what it was before the event was added. But this is useless and
wasteful because nothing is going to be using that write_stamp for
calculations as it still will not match the before_stamp.
Remove this useless update, and in doing so, we remove another
cmpxchg64()!
Also update the comments to reflect this change as well as remove some
extra white space in another comment.

If an update to an event is interrupted by another event between the time
the initial event allocated its buffer and where it wrote to the
write_stamp, the code try to reset the write stamp back to the what it had
just overwritten. It knows that it was overwritten via checking the
before_stamp, and if it didn't match what it wrote to the before_stamp
before it allocated its space, it knows it was overwritten.
To put back the write_stamp, it uses the before_stamp it read. The problem
here is that by writing the before_stamp to the write_stamp it makes the
two equal again, which means that the write_stamp can be considered valid
as the last timestamp written to the ring buffer. But this is not
necessarily true. The event that interrupted the event could have been
interrupted in a way that it was interrupted as well, and can end up
leaving with an invalid write_stamp. But if this happens and returns to
this context that uses the before_stamp to update the write_stamp again,
it can possibly incorrectly make it valid, causing later events to have in
correct time stamps.
As it is OK to leave this function with an invalid write_stamp (one that
doesn't match the before_stamp), there's no reason to try to make it valid
again in this case. If this race happens, then just leave with the invalid
write_stamp and the next event to come along will just add a absolute
timestamp and validate everything again.
Bonus points: This gets rid of another cmpxchg64!

When lockdep is enabled, the for_each_sibling_event(sibling, event)
macro checks that event->ctx->mutex is held. When creating a new group
leader event, we call perf_event_validate_size() on a partially
initialized event where event->ctx is NULL, and so when
for_each_sibling_event() attempts to check event->ctx->mutex, we get a
splat, as reported by Lucas De Marchi:
WARNING: CPU: 8 PID: 1471 at kernel/events/core.c:1950 __do_sys_perf_event_open+0xf37/0x1080
This only happens for a new event which is its own group_leader, and in
this case there cannot be any sibling events. Thus it's safe to skip the
check for siblings, which avoids having to make invasive and ugly
changes to for_each_sibling_event().
Avoid the splat by bailing out early when the new event is its own
group_leader.

Turns out we made a silly mistake when coming up with OR inheritance on
nouveau. On pre-DCB 4.1, iors are statically routed to output paths via the
DCB. On later generations iors are only routed to an output path if they're
actually being used. Unfortunately, it appears with NVIF_OUTP_INHERIT_V0 we
make the mistake of assuming the later is true on all generations, which is
currently leading us to return bogus ior -> head assignments through nvif,
which causes WARN_ON().
So - fix this by verifying that we actually know that there's a head
assigned to an ior before allowing it to be inherited through nvif. This
-should- hopefully fix the WARN_ON on GT218 reported by Borislav.

Commit 12c9b05da918 ("drm/nouveau/imem: support allocations not
preserved across suspend") uses container_of() to cast from struct
nvkm_memory to struct nvkm_instobj, assuming that all instance objects
are derived from struct nvkm_instobj. For the gk20a family that's not
the case and they are derived from struct nvkm_memory instead. This
causes some subtle data corruption (nvkm_instobj.preserve ends up
mapping to gk20a_instobj.vaddr) that causes a NULL pointer dereference
in gk20a_instobj_acquire_iommu() (and possibly elsewhere) and also
prevents suspend/resume from working.
Fix this by making struct gk20a_instobj derive from struct nvkm_instobj
instead.

In 8e9fad0e70b7 "io_uring: Add io_uring command support for sockets"
you've got an include of asm-generic/ioctls.h done in io_uring/uring_cmd.c.
That had been done for the sake of this chunk -
+ ret = prot->ioctl(sk, SIOCINQ, &arg);
+ if (ret)
+ return ret;
+ return arg;
+ case SOCKET_URING_OP_SIOCOUTQ:
+ ret = prot->ioctl(sk, SIOCOUTQ, &arg);
SIOC{IN,OUT}Q are defined to symbols (FIONREAD and TIOCOUTQ) that come from
ioctls.h, all right, but the values vary by the architecture.
FIONREAD is
0x467F on mips
0x4004667F on alpha, powerpc and sparc
0x8004667F on sh and xtensa
0x541B everywhere else
TIOCOUTQ is
0x7472 on mips
0x40047473 on alpha, powerpc and sparc
0x80047473 on sh and xtensa
0x5411 everywhere else
->ioctl() expects the same values it would've gotten from userland; all
places where we compare with SIOC{IN,OUT}Q are using asm/ioctls.h, so
they pick the correct values. io_uring_cmd_sock(), OTOH, ends up
passing the default ones.

The current Atmel SPI controller driver (v2) behaves incorrectly when
using two SPI devices with different clock polarities and GPIO CS.
When switching from one device to another, the controller driver first
enables the CS and then applies whatever configuration suits the targeted
device (typically, the polarities). The side effect of such order is the
apparition of a spurious clock edge after enabling the CS when the clock
polarity needs to be inverted wrt. the previous configuration of the
controller.
This parasitic clock edge is problematic when the SPI device uses that edge
for internal processing, which is perfectly legitimate given that its CS
was asserted. Indeed, devices such as HVS8080 driven by driver gpio-sr in
the kernel are shift registers and will process this first clock edge to
perform a first register shift. In this case, the first bit gets lost and
the whole data block that will later be read by the kernel is all shifted
by one.
Current behavior:
The actual switching of the clock polarity only occurs after the CS
when the controller sends the first message:
CLK ------------\ /-\ /-\
| | | | | . . .
\---/ \-/ \
CS -----\
|
\------------------
^ ^ ^
| | |
| | Actual clock of the message sent
| |
| Change of clock polarity, which occurs with the first
| write to the bus. This edge occurs when the CS is
| already asserted, and can be interpreted as
| the first clock edge by the receiver.
|
GPIO CS toggle
This issue is specific to this controller because while the SPI core
performs the operations in the right order, the controller however does
not. In practice, the controller only applies the clock configuration right
before the first transmission.
So this is not a problem when using the controller's dedicated CS, as the
controller does things correctly, but it becomes a problem when you need to
change the clock polarity and use an external GPIO for the CS.
One possible approach to solve this problem is to send a dummy message
before actually activating the CS, so that the controller applies the clock
polarity beforehand.
New behavior:
CLK ------\ /-\ /-\ /-\ /-\
| | | ... | | | | ... | |
\------/ \- -/ \------/ \- -/ \------
CS -\/-----------------------\
|| |
\/ \---------------------
^ ^ ^ ^ ^
| | | | |
| | | | Expected clock cycles when
| | | | sending the message
| | | |
| | | Actual GPIO CS activation, occurs inside
| | | the driver
| | |
| | Dummy message, to trigger clock polarity
| | reconfiguration. This message is not received and
| | processed by the device because CS is low.
| |
| Change of clock polarity, forced by the dummy message. This
| time, the edge is not detected by the receiver.
|
This small spike in CS activation is due to the fact that the
spi-core activates the CS gpio before calling the driver's
set_cs callback, which deactivates this gpio again until the
clock polarity is correct.
To avoid having to systematically send a dummy packet, the driver keeps
track of the clock's current polarity. In this way, it only sends the dummy
packet when necessary, ensuring that the clock will have the correct
polarity when the CS is toggled.
There could be two hardware problems with this patch:
1- Maybe the small CS activation peak can confuse SPI devices
2- If on a design, a single wire is used to select two devices depending
on its state, the dummy message may disturb them.

But these values are used by the host drivers internally for controller
configuration. When the OPP support is enabled in devicetree, these values
will be 0, causing boot issues on the respective platforms.
So add support to parse the min_freq and max_freq of all clocks while
parsing the OPP table.

Starting with commit 4e51bf44a03a ("net: bridge: move the switchdev
object replay helpers to "push" mode") the switchdev_bridge_port_offload()
helper was extended with the intention to provide switchdev drivers easy
access to object addition and deletion replays. This works by calling
the replay helpers with non-NULL notifier blocks.
In the same commit, the dpaa2-switch driver was updated so that it
passes valid notifier blocks to the helper. At that moment, no
regression was identified through testing.
In the meantime, the blamed commit changed the behavior in terms of
which ports get hit by the replay. Before this commit, only the initial
port which identified itself as offloaded through
switchdev_bridge_port_offload() got a replay of all port objects and
FDBs. After this, the newly joining port will trigger a replay of
objects on all bridge ports and on the bridge itself.
This behavior leads to errors in dpaa2_switch_port_vlans_add() when a
VLAN gets installed on the same interface multiple times.
The intended mechanism to address this is to pass a non-NULL ctx to the
switchdev_bridge_port_offload() helper and then check it against the
port's private structure. But since the driver does not have any use for
the replayed port objects and FDBs until it gains support for LAG
offload, it's better to fix the issue by reverting the dpaa2-switch
driver to not ask for replay. The pointers will be added back when we
are prepared to ignore replays on unrelated ports.

Once again syzbot is able to crash the kernel in skb_segment() [1]
GSO_BY_FRAGS is a forbidden value, but unfortunately the following
computation in skb_segment() can reach it quite easily :
mss = mss * partial_segs;
65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to
a bad final result.
Make sure to limit segmentation so that the new mss value is smaller
than GSO_BY_FRAGS.

When freeing PD/PT with shadows it can happen that the shadow
destruction races with detaching the PD/PT from the VM causing a NULL
pointer dereference in the invalidation code.
Fix this by detaching the the PD/PT from the VM first and then
freeing the shadow instead.

commit 751e293f2c99 ("drm/amd: Move microcode init from sw_init to
early_init for SDMA v2.4") made a fateful mistake in
`adev->sdma.num_instances` wasn't declared when sdma_v2_4_init_microcode()
was run. This caused probing to fail.
Move the declaration to right before sdma_v2_4_init_microcode().

Add begin/end_use ring callbacks to disallow GFXOFF when
SDMA work is submitted and allow it again afterward.
This should avoid corner cases where GFXOFF is erroneously
entered when SDMA is still active. For now just allow/disallow
GFXOFF in the begin and end helpers until we root cause the
issue. This should not impact power as SDMA usage is pretty
minimal and GFXOSS should not be active when SDMA is active
anyway, this just makes it explicit.
v2: move everything into sdma5.2 code. No reason for this
to be generic at this point.
v3: Add comments in new code

There are some wrong return values check in sign-file when call OpenSSL
API. The ERR() check cond is wrong because of the program only check the
return value is < 0 which ignored the return val is 0. For example:
1. CMS_final() return 1 for success or 0 for failure.
2. i2d_CMS_bio_stream() returns 1 for success or 0 for failure.
3. i2d_TYPEbio() return 1 for success and 0 for failure.
4. BIO_free() return 1 for success and 0 for failure.
