bpf: Sync asm-generic/socket.h to tools/ SO_DETACH_REUSEPORT_BPF is needed for the test in the next patch. It is defined in the socket.h. Signed-off-by: Martin KaFai Lau <kafai@fb.com> Reviewed-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

net: SO_RCVMARK socket option for SO_MARK with recvmsg() Adding a new socket option, SO_RCVMARK, to indicate that SO_MARK should be included in the ancillary data returned by recvmsg(). Renamed the sock_recv_ts_and_drops() function to sock_recv_cmsgs().

scm: add SO_PASSPIDFD and SCM_PIDFD Implement SCM_PIDFD, a new type of CMSG type analogical to SCM_CREDENTIALS, but it contains pidfd instead of plain pid, which allows programmers not to care about PID reuse problem. We mask SO_PASSPIDFD feature if CONFIG_UNIX is not builtin because it depends on a pidfd_prepare() API which is not exported to the kernel modules. Idea comes from UAPI kernel group: https://uapi-group.org/kernel-features/ Big thanks to Christian Brauner and Lennart Poettering for productive discussions about this. Cc: "David S.

net: core: add getsockopt SO_PEERPIDFD Add SO_PEERPIDFD which allows to get pidfd of peer socket holder pidfd. This thing is direct analog of SO_PEERCRED which allows to get plain PID. Cc: "David S.
