  "message": "posix-timers: fix creation race\n\nsys_timer_create() sets -\u003eit_process and unlocks -\u003esiglock, then checks\ntmr-\u003eit_sigev_notify to define if get_task_struct() is needed.\n\nWe already passed -\u003eit_id to the caller, another thread can delete this timer\nand free its memory in between.\n\nAs a minimal fix, move this code under -\u003esiglock, sys_timer_delete() takes it\ntoo before calling release_posix_timer().  A proper serialization would be to\ntake -\u003eit_lock, we add a partly initialized timer on posix_timers_id, not\ngood.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
