Subject: [PATCH 2/2] packet: fix race condition in packet_set_ring
|
||||
|
||||
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.")
