[SRU][J][PULL] Fixes for CVE-2024-2658{3,4,5}

[Juerg Haefliger]

[ Impact ]

CVE-2024-26583 (https://ubuntu.com/security/CVE-2024-26583)
CVE-2024-26584 (https://ubuntu.com/security/CVE-2024-26584)
CVE-2024-26585 (https://ubuntu.com/security/CVE-2024-26585)

[ Test case ]

1) Enable async crypto:
    $ modprobe tcrypt alg="pcrypt(generic-gcm-aesni)" type=3
2) Enable TLS function tracing:
    $ echo function_graph > /sys/kernel/tracing/current_tracer
    $ echo 'tls_*:mod:tls' > /sys/kernel/tracing/set_ftrace_filter
3) Run TLS kernel selftests from v6.8:
    $ ./linux-6.8/tools/testing/selftests/net/tls
4) Verify:
    - No call traces in the kernel log
    - All modified TLS functions were called
    - No additional unexpected TLS test failures

[ Where problems could occur ]

Modifications are all limited to the tls module so only applications
that use kernel TLS might suffer.

[ Notes ]

1) 5.15 is not vulnerable to CVE-2024-26582
2) All CVEs are fixed by a single upstream patches so the fixes are
   all rolled into a single PR as well
3) The first 19 patches are stable patches from linux-5.15.y
