## Description

In the Linux kernel, the following vulnerability has been resolved:
net, neigh: Do not trigger immediate probes on NUD\_FAILED from
neigh\_managed\_work
syzkaller was able to trigger a deadlock for NTF\_MANAGED entries [0]:
kworker/0:16/14617 is trying to acquire lock:
ffffffff8d4dd370 (&tbl->lock){++-.}-{2:2}, at:
\_\_\_neigh\_create+0x9e1/0x2990 net/core/neighbour.c:652
[...]
but task is already holding lock:
ffffffff8d4dd370 (&tbl->lock){++-.}-{2:2}, at:
neigh\_managed\_work+0x35/0x250 net/core/neighbour.c:1572
The neighbor entry turned to NUD\_FAILED state, where \_\_neigh\_event\_send()
triggered an immediate probe as per commit cd28ca0a3dd1 ("neigh: reduce
arp latency") via neigh\_probe() given table lock was held.
One option to fix this situation is to defer the neigh\_probe() back to
the neigh\_timer\_handler() similarly as pre cd28ca0a3dd1. For the case
of NTF\_MANAGED, this deferral is acceptable given this only happens on
actual failure state and regular / expected state is NUD\_VALID with the
entry already present.
The fix adds a parameter to \_\_neigh\_event\_send() in order to communicate
whether immediate probe is allowed or disallowed. Existing call-sites
of neigh\_event\_send() default as-is to immediate probe. However, the
neigh\_managed\_work() disables it via use of neigh\_event\_send\_probe().
