[ Upstream commit 3c44d31cb34ce4eb8311a2e73634d57702948230 ]
Algorithm registration is usually carried out during module init,
where as little work as possible should be carried out. The SIMD
code violated this rule by allocating a tfm, this then triggers a
full test of the algorithm which may dead-lock in certain cases.
SIMD is only allocating the tfm to get at the alg object, which is
in fact already available as it is what we are registering. Use
that directly and remove the crypto_alloc_tfm call.
Also remove some obsolete and unused SIMD API.

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tc is always in the range 0 - cfg->tcs. And as cfg->tcs is a u8,
the range is 0 - 255. Further, on inspecting the code, it seems
that cfg->tcs will never be more than AQ_CFG_TCS_MAX (8), so
the range is actually 0 - 8.
So, it seems that the condition that GCC flags will not occur.
But, nonetheless, it would be nice if it didn't emit the warning.
It seems that this can be achieved by changing the format specifier
from %d to %u, in which case I believe GCC recognises an upper bound
on the range of tc of 0 - 255. After some experimentation I think
this is due to the combination of the use of %u and the type of
cfg->tcs (u8).
Empirically, updating the type of the tc variable to unsigned int
has the same effect.
As both of these changes seem to make sense in relation to what the code
is actually doing - iterating over unsigned values - do both.

The NETLINK_FIB_LOOKUP netlink family can be used to perform a FIB
lookup according to user provided parameters and communicate the result
back to user space.
However, unlike other users of the FIB lookup API, the upper DSCP bits
and the ECN bits of the DS field are not masked, which can result in the
wrong result being returned.
Solve this by masking the upper DSCP bits and the ECN bits using
IPTOS_RT_MASK.
The structure that communicates the request and the response is not
exported to user space, so it is unlikely that this netlink family is
actually in use [1].

Coverity reported that u8 rx_mask << 24 will become signed 32 bits, which
casting to unsigned 64 bits will do sign extension. For example,
putting 0x80000000 (signed 32 bits) to a u64 variable will become
0xFFFFFFFF_80000000.
The real case we meet is:
rx_mask[0...3] = ff ff 00 00
ra_mask = 0xffffffff_ff0ff000
After this fix:
rx_mask[0...3] = ff ff 00 00
ra_mask = 0x00000000_ff0ff000
Fortunately driver does bitwise-AND with incorrect ra_mask and supported
rates (1ss and 2ss rate only) afterward, so the final rate mask of
original code is still correct.

It is not particularly useful to release locks (the EC mutex and the
ACPI global lock, if present) and re-acquire them immediately thereafter
during EC address space accesses in acpi_ec_space_handler().
First, releasing them for a while before grabbing them again does not
really help anyone because there may not be enough time for another
thread to acquire them.
Second, if another thread successfully acquires them and carries out
a new EC write or read in the middle if an operation region access in
progress, it may confuse the EC firmware, especially after the burst
mode has been enabled.
Finally, manipulating the locks after writing or reading every single
byte of data is overhead that it is better to avoid.
Accordingly, modify the code to carry out EC address space accesses
entirely without releasing the locks.

Occasionally when the system goes into pm_suspend, the suspend might fail
due to a PHY access error on the network adapter. Previously, this would
have caused the whole system to fail to go to a low power state.
An example of this was reported in the following Bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=205015
[ 1663.694828] e1000e 0000:00:19.0 eth0: Failed to disable ULP

[22909.393861] PM: Device 0000:00:1f.6 failed to suspend async: error -2
This can be avoided by changing the return values of __e1000_shutdown and
e1000e_pm_suspend functions so that they always return 0 (success). This
is consistent with what other drivers do.
If the e1000e driver encounters a hardware error during suspend, potential
side effects include slightly higher power draw or non-working wake on
LAN. This is preferred to a system-level suspend failure, and a warning
message is written to the system log, so that the user can be aware that
the LAN controller experienced a problem during suspend.

This shouldn't happen at all, since in station mode all MMPDUs
go through the TXQ for the STA, and not this function. There
may or may not be a race in mac80211 through which this might
happen for some frames while a station is being added, but in
that case we can also just drop the frame and pretend the STA
didn't exist yet.
Also, the code is simply wrong since it uses deflink, and it's
not easy to fix it since the mvmvif->ap_sta pointer cannot be
used without the mutex, and perhaps the right link might not
even be known.
Just drop the frame at that point instead of trying to fix it

When the upper layer requests to cancel an ongoing scan, a race
is possible in which by the time the driver starts to handle the
upper layers scan cancel flow, the FW already completed handling
the scan request and the driver received the scan complete
notification but still did not handle the notification. In such a
case the FW will simply ignore the scan abort request coming from
the driver, no notification would arrive from the FW and the entire
abort flow would be considered a failure.
To better handle this, check the status code returned by the FW for
the scan abort command. In case the status indicates that
no scan was aborted, complete the scan abort flow with success, i.e.,
the scan was aborted, as the flow is expected to consume the scan
complete notification.

'ice_sched_node' structure. But incorrect types are used as sizeof()
arguments in these calls (structures instead of pointers) which leads to
over allocation of memory.
Adjust over allocation of memory by correcting types in devm_kcalloc()
sizeof() arguments.

Use the generic crypto_authenc_extractkeys helper instead of custom
parsing code that is slightly broken. Also fix a number of memory
leaks by moving memory allocation from setkey to init_tfm (setkey
can be called multiple times over the life of a tfm).
Finally accept all hash key lengths by running the digest over
extra-long keys.

The macros FOUR_ROUNDS_AND_SCHED and DO_4ROUNDS rely on an
unexpected/undocumented behavior of the GNU assembler, which might
change in the future
(https://sourceware.org/bugzilla/show_bug.cgi?id=32073).
M (1) (2) // 1 arg !? Future: 2 args
M 1 + 2 // 1 arg !? Future: 3 args
M 1 2 // 2 args
Add parentheses around the single arguments to support future GNU
assembler and LLVM integrated assembler (when the IsOperator hack from
the following link is dropped).

Syzbot points out that skb_trim() has a sanity check on the existing length of
the skb, which can be uninitialised in some error paths. The intent here is
clearly just to reset the length to zero before resubmitting, so switch to
calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length()
already contains a call to skb_reset_tail_pointer(), so remove the redundant
call.
The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar
usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

NFS-style symlinks have target location always stored in NFS/UNIX form
where backslash means the real UNIX backslash and not the SMB path
separator.
So do not mangle slash and backslash content of NFS-style symlink during
readlink() syscall as it is already in the correct Linux form.
This fixes interoperability of NFS-style symlinks with backslashes created
by Linux NFS3 client throw Windows NFS server and retrieved by Linux SMB
client throw Windows SMB server, where both Windows servers exports the
same directory.

ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.
Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract
variable len.
Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.
Major and minor rdev values are present also only when reparse buffer is
large enough. Check for reparse buffer size before calling reparse_mkdev().

In most Linux distribution kernels, the SND is set to m, in such a
case, when booting the kernel on i.MX8MP EVK board, there is a
warning calltrace like below:
Call trace:
snd_card_init+0x484/0x4cc [snd]
snd_card_new+0x70/0xa8 [snd]
snd_soc_bind_card+0x310/0xbd0 [snd_soc_core]
snd_soc_register_card+0xf0/0x108 [snd_soc_core]
devm_snd_soc_register_card+0x4c/0xa4 [snd_soc_core]
That is because the card.owner is not set, a warning calltrace is
raised in the snd_card_init() due to it.

[ Upstream commit 1c801e7f77445bc56e5e1fec6191fd4503534787 ]
Some time ago, we introduced the obey_preferred_dacs flag for choosing
the DAC/pin pairs specified by the driver instead of parsing the
paths. This works as expected, per se, but there have been a few
cases where we forgot to set this flag while preferred_dacs table is
already set up. It ended up with incorrect wiring and made us
wondering why it doesn't work.
Basically, when the preferred_dacs table is provided, it means that
the driver really wants to wire up to follow that. That is, the
presence of the preferred_dacs table itself is already a "do-it"
flag.
In this patch, we simply replace the evaluation of obey_preferred_dacs
flag with the presence of preferred_dacs table for fixing the
misbehavior. Another patch to drop of the obsoleted flag will
follow.
