  "message": "signals: check_kill_permission: check session under tasklist_lock\n\nThis wasn\u0027t documented, but as Atsushi Tsuji pointed out\ncheck_kill_permission() needs tasklist_lock for task_session_nr().  I missed\nthis fact when removed tasklist from the callers.\n\nChange check_kill_permission() to take tasklist_lock for the SIGCONT case.\nRe-order security checks so that we take tasklist_lock only if/when it is\nactually needed.  This is a minimal fix for now, tasklist will be removed\nlater.\n\nAlso change the code to use task_session() instead of task_session_nr().\n\nAlso, remove the SIGCONT check from cap_task_kill(), it is bogus (and the\nwhole function is bogus.  Serge, Eric, why it is still alive?).\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Atsushi Tsuji \u003ca-tsuji@bk.jp.nec.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
