According to Oleg the PTRACE_KILL doesn't and was-not-supposed-to work. Thus, kill tasks to final state explicitly and just detach from them. Signed-off-by:

Since we need to operate with sysctls pretty heavy, better to add some common engine for all handlers. Based-on-patch-from: Pavel Emelyanov <xemul@parallels.com> Signed-off-by:

I added two mechanism of synchronization. The second one is better. This patch deletes the first one. Before we had an entry (pid and lock) for each tasks and all this entries were shared between all processes. Now we don't need "lock" and we use pids from crtools to kill all processes if someone failed. v2: s/malloc/xmalloc Signed-off-by:

When creating zombies we must wait for them to appear to test that we do support zombies, but not some transient state. But the thing is that we cannot use wait() or any other synchronous call here, thus we have to suck and use sleep(1) :( Signed-off-by:

Strange fact, but a task seems to live for some time after PTRACE_KILL :( Don't know yet why this happens, I'm poking Oleg on that, but this one makes it die right at once. The streaming file read test passes after this. Signed-off-by:

This commit brings the former "Rewrite task/threads stopping engine" commit back. Handling it separately is too complex so better try to handle it in-place. Note some tests might fault, it's expected. --- Stopping tasks with STOP and proceeding with SEIZE is actually excessive -- the SEIZE if enough. Moreover, just killing a task with STOP is also racy, since task should be given some time to come to sleep before its proc can be parsed. Rewrite all this code to SEIZE task and all its threads from the very beginning. With this we can distinguish stopped task state and migrate it properly (not supported now, need to implement). This thing however has one BIG problem -- after we SEIZE-d a task we should seize it's threads, but we should do it in a loop -- reading /proc/pid/task and seizing them again and again, until the contents of this dir stops changing (not done now). Besides, after we seized a task and all its threads we cannot scan it's children list once -- task can get reparented to init and any task's child can call clone with CLONE_PARENT flag thus repopulating the children list of the already seized task (not done also) This patch is ugly, yes, but splitting it doesn't help to review it much, sorry :( Signed-off-by:
