Subject: [PATCH 4.4 0/7] fs/proc: Stop reporting eip and esp in
Date: Mon, 2 Dec 2019 16:35:12 +0800 [thread overview]
Message-ID: <20191202083519.23138-1-yi.zhang@huawei.com> (raw)
Reporting eip and esp fields on a non-current task is dangerous,
so backport this series for 4.4 to fix protential oops and info leak
problems. The first 3 patch are depended on the 6/7 patch.
Alexey Dobriyan (1):
proc: fix coredump vs read /proc/*/stat race
Andy Lutomirski (3):
sched/core: Allow putting thread_info into task_struct
sched/core: Add try_get_task_stack() and put_task_stack()
fs/proc: Stop reporting eip and esp in /proc/PID/stat
Heiko Carstens (1):
sched/core, x86: Make struct thread_info arch specific again
John Ogness (2):
fs/proc: Report eip/esp in /prod/PID/stat for coredumping
fs/proc/array.c: allow reporting eip/esp for all coredumping threads
