Yu reported on shortcoming nameling that the signal causing the coredump was available before the crashing process was reaped. The previous systemd coredump container interface requires the coredump file descriptor, and basic information including the signal number to be sent to the container. This means we need to have the signal number available before sending the coredump to the container. In general, the extension makes sense and fits with the rest of the coredump information. In addition to this extension this fixes a bunch of the tests that were failing and reworks the publication mechanism for exit and coredump info retrievable via the pidfd ioctl. * patches from https://patch.msgid.link/20251028-work-coredump-signal-v1-0-ca449b7b7aa0@kernel.org: (22 commits) selftests/coredump: add second PIDFD_INFO_COREDUMP_SIGNAL test selftests/coredump: add first PIDFD_INFO_COREDUMP_SIGNAL test selftests/coredump: ignore ENOSPC errors selftests/coredump: add debug logging to coredump socket protocol tests selftests/coredump: add debug logging to coredump socket tests selftests/coredump: add debug logging to test helpers selftests/coredump: handle edge-triggered epoll correctly selftests/coredump: fix userspace coredump client detection selftests/coredump: fix userspace client detection selftests/coredump: split out coredump socket tests selftests/coredump: split out common helpers selftests/pidfd: add second supported_mask test selftests/pidfd: add first supported_mask test selftests/pidfd: update pidfd header pidfs: expose coredump signal pidfs: drop struct pidfs_exit_info pidfs: prepare to drop exit_info pointer pidfd: add a new supported_mask field pidfs: add missing BUILD_BUG_ON() assert on struct pidfd_info pidfs: add missing PIDFD_INFO_SIZE_VER1 ...
