  "message": "[PATCH] send_sigqueue: simplify and fix the race\n\nsend_sigqueue() checks PF_EXITING, then locks p-\u003esighand-\u003esiglock.  This is\nunsafe: \u0027p\u0027 can exit in between and set -\u003esighand \u003d NULL.  The race is\ntheoretical, the window is tiny and irqs are disabled by the caller, so I\ndon\u0027t think we need the fix for -stable tree.\n\nConvert send_sigqueue() to use lock_task_sighand() helper.\n\nAlso, delete \u0027p-\u003eflags \u0026 PF_EXITING\u0027 re-check, it is unneeded and the\ncomment is wrong.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
