      "message": "Remove the global thread list.\n\nAnother release, another attempt to fix this bug.\n\nThis change affects pthread_detach, pthread_getcpuclockid,\npthread_getschedparam/pthread_setschedparam, pthread_join, and pthread_kill:\ninstead of returning ESRCH when passed an invalid pthread_t, they\u0027ll now SEGV.\n\nNote that this doesn\u0027t change behavior as much as you might think: the old\nlookup only held the global thread list lock for the duration of the lookup,\nso there was still a race between that and the dereference in the caller,\ngiven that callers actually need the tid to pass to some syscall or other,\nand sometimes update fields in the pthread_internal_t struct too.\n\nWe can\u0027t check thread-\u003etid against 0 to see whether a pthread_t is still\nvalid because a dead thread gets its thread struct unmapped along with its\nstack, so the dereference isn\u0027t safe.\n\nTaking the affected functions one by one:\n\n* pthread_getcpuclockid and pthread_getschedparam/pthread_setschedparam\n  should be fine. Unsafe calls to those seem highly unlikely.\n\n* Unsafe pthread_detach callers probably want to switch to\n  pthread_attr_setdetachstate instead, or using pthread_detach(pthread_self())\n  from the new thread\u0027s start routine rather than doing the detach in the\n  parent.\n\n* pthread_join calls should be safe anyway, because a joinable thread won\u0027t\n  actually exit and unmap until it\u0027s joined. If you\u0027re joining an\n  unjoinable thread, the fix is to stop marking it detached. If you\u0027re\n  joining an already-joined thread, you need to rethink your design.\n\n* Unsafe pthread_kill calls aren\u0027t portably fixable. (And are obviously\n  inherently non-portable as-is.) The best alternative on Android is to\n  use pthread_gettid_np at some point that you know the thread to be alive,\n  and then call kill/tgkill directly. That\u0027s still not completely safe\n  because if you\u0027re too late, the tid may have been reused, but then your\n  code is inherently unsafe anyway.\n\nIf we find too much code is still broken, we can come back and disable\nthe global thread list lookups for anything targeting \u003e\u003d O and then have\nanother go at really removing this in P...\n\nBug: http://b/19636317\nTest: N6P boots, bionic tests pass\nChange-Id: Ia92641212f509344b99ee2a9bfab5383147fcba6\n"
