Cong Wang 69139d2919 vsock: fix recursive ->recvmsg calls ... After a vsock socket has been added to a BPF sockmap, its prot->recvmsg has been replaced with vsock_bpf_recvmsg(). Thus the following recursiion could happen: vsock_bpf_recvmsg() -> __vsock_recvmsg() -> vsock_connectible_recvmsg() -> prot->recvmsg() -> vsock_bpf_recvmsg() again We need to fix it by calling the original ->recvmsg() without any BPF sockmap logic in __vsock_recvmsg(). Fixes: 634f1a7110 ("vsock: support sockmap") Reported-by: syzbot+bdb4bd87b5e22058e2a4@syzkaller.appspotmail.com Tested-by: syzbot+bdb4bd87b5e22058e2a4@syzkaller.appspotmail.com Cc: Bobby Eshleman <bobby.eshleman@bytedance.com> Cc: Michael S.
