Once upon a time it used to be much bigger, but these days there's no point whatsoever keeping it in fs/inode.c, especially since it's not even needed as initializer for ->drop_inode() - it's the default and leaving ->drop_inode NULL will do just as well.

2012-03-20exec: move de_thread()->setmax_mm_hiwater_rss() into exec_mmap()Oleg Nesterov
Minor cleanup. de_thread()->setmax_mm_hiwater_rss() looks a bit strange, move it into exec_mmap() which plays with old_mm. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-03-20exit_signal: fix the "parent has changed security domain" logicOleg Nesterov
exit_notify() changes ->exit_signal if the parent already did exec. This doesn't really work, we are not going to send the signal now if there is another live thread or the exiting task is traced. The parent can exec before the last dies or the tracer detaches. Move this check into do_notify_parent() which actually sends the signal. The user-visible change is that we do not change ->exit_signal, and thus the exiting task is still "clone children" for do_wait()->eligible_child(__WCLONE). Hopefully this is fine, the current logic is racy anyway. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-03-20exit_signal: simplify the "we have changed execution domain" logicOleg Nesterov
exit_notify() checks "tsk->self_exec_id != tsk->parent_exec_id" to handle the "we have changed execution domain" case. We can change do_thread() to always set ->exit_signal = SIGCHLD and remove this check to simplify the code. We could change setup_new_exec() instead, this looks more logical because it increments ->self_exec_id. But note that de_thread() already resets ->exit_signal if it changes the leader, let's keep both changes close to each other. Note that we change ->exit_signal lockless, this changes the rules. Thereafter ->exit_signal is not stable under tasklist but this is fine, the only possible change is OLDSIG -> SIGCHLD. This can race with eligible_child() but the race is harmless. We can race with reparent_leader() which changes our ->exit_signal in parallel, but it does the same change to SIGCHLD. The noticeable user-visible change is that the execing task is not "visible" to do_wait()->eligible_child(__WCLONE) right after exec. To me this looks more logical, and this is consistent with mt case. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-03-20CLONE_PARENT shouldn't allow to set ->exit_signalOleg Nesterov
The child must not control its ->exit_signal, it is the parent who decides which signal the child should use for notification. This means that CLONE_PARENT should not use "clone_flags & CSIGNAL", the forking task is the sibling of the new process and their parent doesn't control exit_signal in this case. This patch uses ->exit_signal of the forking process, but perhaps we should simply use SIGCHLD. We read group_leader->exit_signal lockless, this can race with the ORIGINAL_SIGNAL -> SIGCHLD transition, but this is fine. Potentially this change allows to kill self_exec_id/parent_exec_id.

2012-03-20Fix pppol2tp getsockname()Benjamin LaHaise
While testing L2TP functionality, I came across a bug in getsockname(). The IP address returned within the pppol2tp_addr's addr memember was not being set to the IP address in use. This bug is caused by using inet_sk() on the wrong socket (the L2TP socket rather than the underlying UDP socket), and was likely introduced during the addition of L2TPv3 support.
