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: -

In case if there some error happened better to know which exactly file failed on open, for example | Error (files-reg.c:535): Can't open file /lib64/libgcc_s-4.4.7-20120601.so.1 on restore: No such file or directory 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:
