Biederman <ebiederm@xmission.com> # Date: Thu Jun 10 15:11:11 2021 -0500 # # coredump: Limit what can interrupt coredumps # # Olivier Langlois has been struggling with coredumps being incompletely written in # processes using io_uring. # # Olivier Langlois <olivier@trillion01.com> writes: # > io_uring is a big user of task_work and any event that io_uring made a # > task waiting for that occurs during the core dump generation will # > generate a TIF_NOTIFY_SIGNAL. # > # > Here are the detailed steps of the problem: # > 1. io_uring calls vfs_poll() to install a task to a file wait queue # > with io_async_wake() as the wakeup function cb from io_arm_poll_handler() # > 2. wakeup function ends up calling task_work_add() with TWA_SIGNAL # > 3. task_work_add() sets the TIF_NOTIFY_SIGNAL bit by calling # > set_notify_signal() # # The coredump code deliberately supports being interrupted by SIGKILL, # and depends upon prepare_signal to filter out all other signals. Now # that signal_pending includes wake ups for TIF_NOTIFY_SIGNAL this hack # in dump_emitted by the coredump code no longer works. # # Make the coredump code more robust by explicitly testing for all of # the wakeup conditions the coredump code supports. This prevents # new wakeup conditions from breaking the coredump code, as well # as fixing the current issue. # # The filesystem code that the coredump code uses already limits # itself to only aborting on fatal_signal_pending. So it should # not develop surprising wake-up reasons either. # # v2: Don't remove the now unnecessary code in prepare_signal. # # Cc: stable@vger.kernel.org # Fixes: 12db8b690010 ("entry: Add support for TIF_NOTIFY_SIGNAL") # Reported-by: Olivier Langlois <olivier@trillion01.com> # Signed-off-by: "Eric W.
