Longest to sh
Added support for calling a subset of socket setsockopts from
BPF_PROG_TYPE_SOCKET_OPS programs. The code was duplicated rather
than making the changes to call the socket setsockopt function because
the changes required would have been larger.
The ops supported are:
SO_RCVBUF
SO_SNDBUF
SO_MA
