From f6ec29a42d7ac3b309a9cef179b686d23986ab98 Mon Sep 17 00:00:00 2001 From: KaiGai Kohei Date: Sun, 25 Jun 2006 05:49:25 -0700 Subject: [PATCH] pacct: avoidance to refer the last thread as a representation of the process When pacct facility generate an 'ac_flag' field in accounting record, it refers a task_struct of the thread which died last in the process. But any other task_structs are ignored. Therefore, pacct facility drops ASU flag even if root-privilege operations are used by any other threads except the last one. In addition, AFORK flag is always set when the thread of group-leader didn't die last, although this process has called execve() after fork(). We have a same matter in ac_exitcode. The recorded ac_exitcode is an exit code of the last thread in the process. There is a possibility this exitcode is not the group leader's one. --- kernel/exit.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'kernel/exit.c') diff --git a/kernel/exit.c b/kernel/exit.c index 819d82c..e76bd02 100644 --- a/kernel/exit.c +++ b/kernel/exit.c @@ -894,8 +894,8 @@ fastcall NORET_TYPE void do_exit(long code) if (group_dead) { hrtimer_cancel(&tsk->signal->real_timer); exit_itimers(tsk->signal); - acct_collect(); } + acct_collect(code, group_dead); if (unlikely(tsk->robust_list)) exit_robust_list(tsk); #if defined(CONFIG_FUTEX) && defined(CONFIG_COMPAT) @@ -907,7 +907,7 @@ fastcall NORET_TYPE void do_exit(long code) exit_mm(tsk); if (group_dead) - acct_process(code); + acct_process(); exit_sem(tsk); __exit_files(tsk); __exit_fs(tsk); -- cgit v1.1
