-From: Philip Pettersson <philip.pettersson@gmail.com>
-
-When packet_set_ring creates a ring buffer it will initialize a
-struct timer_list if the packet version is TPACKET_V3. This value
-can then be raced by a different thread calling setsockopt to
-set the version to TPACKET_V1 before packet_set_ring has finished.
-
-This leads to a use-after-free on a function pointer in the
-struct timer_list when the socket is closed as the previously
-initialized timer will not be deleted.
-
-The bug is fixed by taking lock_sock(sk) in packet_setsockopt when
-changing the packet version while also taking the lock at the start
-of packet_set_ring.
-
-Fixes: f6fb8f100b80 ("af-packet: TPACKET_V3 flexible buffer implementation.")
