https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v4.13.72017-08-16T23:28:47Zptr_ring: use kmalloc_array()2017-08-16T23:28:47ZEric Dumazetedumazet@google.com2017-08-16T17:36:47Zurn:sha1:81fbfe8adaf38d4f5a98c19bebfd41c5d6acaee8
As found by syzkaller, malicious users can set whatever tx_queue_len
on a tun device and eventually crash the kernel.
Lets remove the ALIGN(XXX, SMP_CACHE_BYTES) thing since a small
ring buffer is not fast anyway.
Fixes: 2e0ab8ca83c1 ("ptr_ring: array based FIFO for pointers")

skbs for type safety. Implemented as a set of wrappers around ptr_ring.
