This is useful for directly looking up a task based on class id rather than
having to scan through all open file descriptors.

ifr name is assumed to be a valid string by the kernel, but nothing
was forcing username to pass a valid string.
In turn, this would cause panics as we tried to access the string
past it's valid memory.

Hi all,
On the latest linux-next I'm seeing issues that look like an icmp
socket destruction racing with poll(). It manifests in two ways, first:
BUG: KASAN: slab-out-of-bounds in skb_queue_empty include/linux/skbuff.h:1197
[inline]
BUG: KASAN: slab-out-of-bounds in udp_poll+0x5fb/0x6f0 net/ipv4
16 matches
