This will result in more sane error in case restore is launched on such semi-complete images. Signed-off-by: -

Andrey Vagin authored
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:
