This is usefull if one needs to do some final action before checkpoint is complete. For example in case of online migration one may provide a script which would check the restore procedure on remote note ended without errors, thus the script returns zero code and criu simply kills running instance of application. In turn, if migration failed, the script can return nonzero code and criu won't kill the application but continue its execution instead. https://bugzilla.openvz.org/show_bug.cgi?id=2583Signed-off-by:

PTRACE_SETSIGMASK takes pointer on mask of blocked signals, but sigmask is already pointer. Signed-off-by:
-
Andrey Vagin authored
If a kernel supports PTRACE_SETSIGMASK, criu don't need to execute PARASITE_CMD_INIT and PARASITE_CMD_DAEMONIZE, because the frist command is used only for blocking signals. If criu crashes between these commands, a process state will be corrupted, because all signals remain blocked. Signed-off-by:

We use two commands to get task registers safely. The first command blocked signals, then crtools dumped registers and all per-thread data and the the second command unblocks signals. Currently signals can be blocked with help SETSIGMASK, so we need only one command to dump per-thread data. Signed-off-by:

Currenly we can restore blocking signals with help ptrace, so if registers are restored after command, a process state will not be corrupted if criu crashes. Same as with previous patch -- at the end there will be only two trap commands, so this is OK. Signed-off-by:

Andrey Vagin authored
Pending signals should be saved, so signals should be blocked. Signals are blocked for EACH command, because a chance of destroying a process state should be a small as possible. At the end there will only two "trapped" commands -- to dump thread and to start daemon in parasite, so this doesn't add significant overheads. If crtools is killed between two commands, a dumped process will run continue. Signed-off-by:

tcp_repair_off implicitly modifies SO_REUSEADDR option inside the kernel (thanks avagin@ for pointing this feature out) thus if we are to rollback and restore the former settings of socket -- don't forget to repair this particular one. Signed-off-by:
