Pull networking fixes from David Miller:

 1) Fix sk_psock reference count leak on receive, from Xiyu Yang.

 2) CONFIG_HNS should be invisible, from Geert Uytterhoeven.

 3) Don't allow locking route MTUs in ipv6, RFCs actually forbid this,
    from Maciej Żenczykowski.

 4) ipv4 route redirect backoff wasn't actually enforced, from Paolo
    Abeni.

 5) Fix netprio cgroup v2 leak, from Zefan Li.

 6) Fix infinite loop on rmmod in conntrack, from Florian Westphal.

 7) Fix tcp SO_RCVLOWAT hangs, from Eric Dumazet.

 8) Various bpf probe handling fixes, from Daniel Borkmann.

consideration the effect of compiler optimisations which may occur
when tail-calls are used and marked with the noreturn GCC attribute.
Probed Pointers from BPF / tracing
----------------------------------
::
%pks kernel string
%pus user string
The ``k`` and ``u`` specifiers are used for printing prior probed memory from
either kernel memory (k) or user memory (u). The subsequent ``s`` specifier
results in printing a string. For direct use in regular vsnprintf() the (k)
and (u) annotation is ignored, however, when used out of BPF's bpf_trace_printk(),
for example, it reads the memory it is pointing to without faulting.
