Please consider pulling these changes from the signed vfs-7.4-rc1.shared.net-next.pidfd tag. Thanks!

SO_PASSPIDFD and SO_PEERPIDFD hand out a pidfd for the thread-group leader. A coredump server on the coredump socket can't get a handle on the thread that took the signal and is writing the dump, and anything doing per-thread authentication has the same problem. The sending and the connecting thread are recorded in addition to the thread-group leader and sk_peer_pid becomes an array indexed by pid type. SO_PASSPIDFD_THREAD works like SO_PASSPIDFD but delivers an SCM_PIDFD_THREAD cmsg for the sending thread. Both options are independent so a receiver can ask for both. On SOCK_STREAM sockets recvmsg() only stops merging data at a thread boundary when the receiver asked for a thread pidfd. SO_PEERPIDFD_THREAD returns a pidfd for the thread that called connect(), listen() or socketpair(). pidfs records the coredump on the dumping thread's struct pid too so its pidfd reports it like the leader's does. Selftests for af_unix and the coredump socket are included" * tag 'vfs-7.4-rc1.shared.net-next.pidfd' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: selftests/coredump: check the dumping thread's pidfd pidfs: record the coredump on the dumping thread's pid too selftests/net: SO_PEERPIDFD_THREAD net: add SO_PEERPIDFD_THREAD to get a thread-specific pidfd af_unix: record the pid of the connecting thread net: turn sk_peer_pid into an array indexed by pid type selftests/net: SO_PASSPIDFD_THREAD net: add SO_PASSPIDFD_THREAD to get a thread-specific SCM_PIDFD af_unix: record the pid of the sending thread pid: add helpers to operate on a struct pid array |
