All info about bound sockets are got via socket diag interface. All connected sockets are automatically bound. For other sockets only protocol must be dumped, which is got with help getsockopt. A netlink sockets with pending data are not supported yet and probably will not be supported in a near future. Signed-off-by:

Each zombie sends SIGCHLD to parent. crtools restores all pending signals, so all other signals should be collected. Here is a problems, that signals SIGCHLD can be merged, but crtools should be sure, that all signals are collected. For that a zombie locks a global zombie_lock, which is released by parent. This operation should be done between CR_STATE_RESTORE and CR_STATE_RESTORE_SIGCHLD. Here is one more CR_STATE_RESTORE_ZOMBIES, whic is used for waiting all zombies. v2: clean up v3: rework synchronization v4: rework without additional CR_STATE-s Signed-off-by:

Alexander, could you help me with ARM? I found in glibc sources, that sa_restoer should look like this: ports/sysdeps/unix/sysv/linux/arm/sigrestorer.S .... ENTRY(__cr_restore_rt) CFI mov r7, $SYS_ify(rt_sigreturn) swi 0x0 .fnend END(__cr_restore_rt) v2: Move architecture-dependent code in the proper place v3: Don't add a separate handler for collecting zombies Cc: Alexander Kartashov <alekskartashov@parallels.com> Signed-off-by: -

If a master point has sid, it doesn't mean, that all slave points will have sid. Look at tty03 for example: PID SID TT COMMAND 26748 26748 ? tty03 26749 26749 pts/2 \_ tty03 26750 26750 ? \_ tty03 The second process has not a file descriptor for the ctl tty, but this tty is opened in tty03. v2: If a slave point with sid has not a master point, the option --shell-job must be set and sid isn't restored for such terminals.

The system call open can add O_LARGEFILE. A point is reopend for unsharing a file descriptor. So here are two types of points. One is returned by pipe() and all other ones are got via opening /proc/PID/fd. Currently I know only one difference between these types, it's O_LARGEFILE. Signed-off-by:

I'm really lucky. prepare_ctl_tty: e->fd = get_service_fd(CTL_TTY_OFF); // -1 as fd is not set send_fd_to_self: if (dup2(fd, dfd) != dfd) { // tries to install sfd, but -1 == -1 tty_restore_ctl_terminal: if (!is_service_fd(fd, CTL_TTY_OFF)) return fd == get_service_fd(type); // -1 = -1 Signed-off-by: -
