If a uaccess (e.g. get_user()) triggers a fault and there's a fault signal pending, the handler will return to the uaccess without having performed a uaccess fault fixup, and so the CPU will immediately execute the uaccess instruction again, whereupon it will livelock bouncing between that instruction and the fault handler. https://lore.kernel.org/lkml/20210121123140.GD48431@C02TD0UTHF1T.local/ Cc: stable@vger.kernel.org Reported-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> |
