static
Arrays aesni_simd_skciphers and aesni_simd_skciphers2 are local to the
source and do not need to be in global scope, so make them static.
Cleans up sparse warnings:
symbol 'aesni_simd_skciphers' was not declared. Should it be static?
symbol 'aesni_simd_skciphers2' was not declared. Should it be static?

When two adjacent TX SGL are processed and parts of both TX SGLs
are pulled into the per-request TX SGL, the wrong per-request
TX SGL entries were updated.
This fixes a NULL pointer dereference when a cipher implementation walks

When built using multi_v7_defconfig, driver does not work on LS1021A:
[...]
caam 1700000.crypto: can't identify CAAM ipg clk: -2

It turns out we have to detect at runtime whether driver is running

Today, md5sum fails with error -ENOKEY because a setkey
function is set for non hmac hashing algs, see strace output below:
mmap(NULL, 378880, PROT_READ, MAP_SHARED, 6, 0) = 0x77f50000
accept(3, 0, NULL) = 7
vmsplice(5, [{"bin/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 378880}], 1, SPLICE_F_MORE|SPLICE_F_GIFT) = 262144

write(2, "Generation of hash for file kcap"..., 50) = 50

This patch ensures that setkey() function is set only

Using RBP as a temporary register breaks frame pointer convention and

Use R13 instead of RBP. Both are callee-saved registers, so the
substitution is straightforward.

Using RBP as a temporary register breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.
Mix things up a little bit to get rid of the RBP usage, without hurting
performance too much. Use RDI instead of RBP for the TBL pointer. That
will clobber CTX, so spill CTX onto the stack and use R12 to read it in
the outer loop. R12 is used as a non-persistent temporary variable
elsewhere, so it's safe to use.
Also remove the unused y4 variable.

Using RBP as a temporary register breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.
There's no need to use RBP as a temporary register for the TBL value,
because it always stores the same value: the address of the K256 table.
Instead just reference the address of K256 directly.

Use RSI instead of RBP for RT1. Since RSI is also used as a the 'dst'

Using RBP as a temporary register breaks frame pointer convention and

Use R15 instead of RBP. R15 can't be used as the RID1 register because
of x86 instruction encoding limitations. So use R15 for CTX and RDI for
CTX. This means that CTX is no longer an implicit function argument.
Instead it needs to be explicitly copied from RDI.

During the change to use aligned buffers, the deallocation code path was
not updated correctly. The current code tries to free the aligned buffer
pointer and not the original buffer pointer as it is supposed to.
Thus, the code is updated to free the original buffer pointer and set
the aligned buffer pointer that is used throughout the code to NULL.

EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

The driver doesn't support events from address families other than IPv4
and IPv6, so ignore them. Otherwise, we risk queueing a work item before
it's initialized.
This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES

IPMR family.

sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill
returns err, in which case it shouldn't mark sk dumped by setting
cb->args[3] as 1 in sctp_sock_dump().
Otherwise, it could cause some asocs to have no parent's sk dumped
in 'ss --sctp'.
So this patch is to not set cb->args[3] when inet_sctp_diag_fill()
returns err in sctp_sock_dump().

Commit 86fdb3448cc1 ("sctp: ensure ep is not destroyed before doing the
dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep
with holding sock and sock lock.
But Paolo noticed that endpoint could be destroyed in sctp_rcv without
sock lock protection. It means the use-after-free issue still could be
triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks
!ep, although it's pretty hard to reproduce.
I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close
and sctp_sock_dump long time.
This patch is to add another param cb_done to sctp_for_each_transport
and dump ep->assocs with holding tsp after jumping out of transport's
traversal in it to avoid this issue.
It can also improve sctp diag dump to make it run faster, as no need
to save sk into cb->args[5] and keep calling sctp_for_each_transport
any more.
This patch is also to use int * instead of int for the pos argument
in sctp_for_each_transport, which could make postion increment only
in sctp_for_each_transport and no need to keep changing cb->args[2]
in sctp_sock_filter and sctp_sock_dump any more.

liujian reported a problem in TCP_USER_TIMEOUT processing with a patch
in tcp_probe_timer() :
https://www.spinics.net/lists/netdev/msg454496.html
After investigations, the root cause of the problem is that we update
skb->skb_mstamp of skbs in write queue, even if the attempt to send a
clone or copy of it failed. One reason being a routing problem.
This patch prevents this, solving liujian issue.
It also removes a potential RTT miscalculation, since
__tcp_retransmit_skb() is not OR-ing TCP_SKB_CB(skb)->sacked with
TCPCB_EVER_RETRANS if a failure happens, but skb->skb_mstamp has
been changed.
A future ACK would then lead to a very small RTT sample and min_rtt
would then be lowered to this too small value.
Tested:

rt_iif is only set to the actual egress device for the output path. The
recent change to consider the l3slave flag when returning IP_PKTINFO
works for local traffic (the correct device index is returned), but it
broke the more typical use case of packets received from a remote host
always returning the VRF index rather than the original ingress device.
Update the fixup to consider l3slave and rt_iif actually getting set.

If the network interface is kept running during suspend, the net core
may call net_device_ops.ndo_start_xmit() while the Ethernet device is
still suspended, which may lead to a system crash.
E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is
driven by a PM controlled clock. If the Ethernet registers are accessed
while the clock is not running, the system will crash with an imprecise
external abort.
As this is a race condition with a small time window, it is not so easy
to trigger at will. Using pm_test may increase your chances:
# echo 0 > /sys/module/printk/parameters/console_suspend
# echo platform > /sys/power/pm_test
# echo mem > /sys/power/state
To fix this, make sure the network interface is quietened during
suspend.

We can enter a deadlock situation because there is no sufficient protection
when ndo_get_stats64() runs in process context to guard against RX or TX NAPI
contexts running in softirq, this can lead to the following lockdep splat and
actual deadlock was experienced as well with an iperf session in the background
and a while loop doing ifconfig + ethtool.
