Commit Message

Geliang Tang July 6, 2023, 8:19 a.m. UTC 
The arguments of socket() need to be changed sometimes like the MPTCP
case in the next commits.

It's too late to add the BPF hooks in BPF_CGROUP_RUN_PROG_INET_SOCK()
in inet_create(). So this patch invokes BPF_CGROUP_RUN_PROG_SOCKINIT()
in __socket_create() to change the arguments.
