[ Upstream commit 16f6458f2478b55e2b628797bc81a4455045c74e ]

The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.

But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.

The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.

Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

a limited lifetime.

Without previous fix, this triggers following crash on net-next:

[ Upstream commit 941ff6f11c020913f5cddf543a9ec63475d7c082 ]

Fix two issues in the reuseport_bpf selftests that were
reported by Linaro CI:

  [...]
  + ./reuseport_bpf
  ---- IPv4 UDP ----
  Testing EBPF mod 10...
  Reprograming, testing mod 5...
  ./reuseport_bpf: ebpf error. log:
  0: (bf) r6 = r1
  1: (20) r0 = *(u32 *)skb[0]
  2: (97) r0 %= 10
  3: (95) exit
  processed 4 insns
  : Operation not permitted
  + echo FAIL
  [...]
  ---- IPv4 TCP ----
  Testing EBPF mod 10...
  ./reuseport_bpf: failed to bind send socket: Address already in use
  + echo FAIL
  [...]

For the former adjust rlimit since this was the cause of
failure for loading the BPF prog, and for the latter add
SO_REUSEADDR.

[ Upstream commit d36f45e5b46723cf2d4147173e18c52d4143176d ]

Address/port initialization should work correctly regardless
of the order in which command line arguments are supplied,
E.g, cfg_port should be used to connect to the remote host
even if it is processed after -D, src/dst address initialization
should not require that [-4|-6] be specified before
the -S or -D args, receiver should be able to bind to *.&lt;cfg_port&gt;

Achieve this by making sure that the address/port structures
are initialized after all command line options are parsed.

Store cfg_port in host-byte order, and use htons()
to set up the sin_port/sin6_port before bind/connect,
so that the network system calls get the correct values
in network-byte order.

[ Upstream commit d36f45e5b46723cf2d4147173e18c52d4143176d ]

Address/port initialization should work correctly regardless
of the order in which command line arguments are supplied,
E.g, cfg_port should be used to connect to the remote host
even if it is processed after -D, src/dst address initialization
should not require that [-4|-6] be specified before
the -S or -D args, receiver should be able to bind to *.&lt;cfg_port&gt;

Achieve this by making sure that the address/port structures
are initialized after all command line options are parsed.

Store cfg_port in host-byte order, and use htons()
to set up the sin_port/sin6_port before bind/connect,
so that the network system calls get the correct values
in network-byte order.
