Merge branch 'net-tls-fix-scatter-gather-list-issues'

Jakub Kicinski says:

====================
net: tls: fix scatter-gather list issues

This series kicked of by a syzbot report fixes three issues around
scatter gather handling in the TLS code. First patch fixes a use-
-after-free situation which may occur if record was freed on error.
This could have already happened in BPF paths, and patch 2 now makes
the same condition occur in non-BPF code.

Patch 2 fixes the problem spotted by syzbot. If encryption failed
we have to clean the end markings from scatter gather list. As
suggested by John the patch frees the record entirely and caller
may retry copying data from user space buffer again.

Third patch fixes a bug in the TLS 1.3 code spotted while working
on patch 2. TLS 1.3 may effectively overflow the SG list which
leads to the BUG() in sg_page() being triggered.

Patch 4 adds a test case which triggers this bug reliably.

Next two patches are small cleanups of dead code and code which
makes dangerous assumptions.

Last but not least two minor improvements to the sockmap tests.

Tested:
- bpf/test_sockmap
- net/tls
- syzbot repro (which used error injection, hence no direct
selftest is added to preserve it).

Merge branch 'net-tls-add-a-TX-lock'

Jakub Kicinski says:

====================
net/tls: add a TX lock

Some time ago Pooja and Mallesham started reporting crashes with
an async accelerator. After trying to poke the existing logic into
shape I came to the conclusion that it can't be trusted, and to
preserve our sanity we should just add a lock around the TX side.

First patch removes the sk_write_pending checks from the write
space callbacks. Those don't seem to have a logical justification.

Patch 2 adds the TX lock and patch 3 associated test (which should
hang with current net).

Mallesham reports that even with these fixes applied the async
accelerator workload still occasionally hangs waiting for socket
memory. I suspect that's strictly related to the way async crypto
is integrated in TLS, so I think we should get these into net or
net-next and move from there.
