Kuniyuki Iwashima 0e81cfd971 af_unix: Move SOCK_PASS{CRED,PIDFD,SEC} to struct sock. ... As explained in the next patch, SO_PASSRIGHTS would have a problem if we assigned a corresponding bit to socket->flags, so it must be managed in struct sock. Mixing socket->flags and sk->sk_flags for similar options will look confusing, and sk->sk_flags does not have enough space on 32bit system. Also, as mentioned in commit 16e5726269 ("af_unix: dont send SCM_CREDENTIALS by default"), SOCK_PASSCRED and SOCK_PASSPID handling is known to be slow, and managing the flags in struct socket cannot avoid that for embryo sockets. Let's move SOCK_PASS{CRED,PIDFD,SEC} to struct sock. While at it, other SOCK_XXX flags in net.h are grouped as enum. Note that assign_bit() was atomic, so the writer side is moved down after lock_sock() in setsockopt(), but the bit is only read once in sendmsg() and recvmsg(), so lock_sock() is not needed there.
