crypto: af_alg - fix backlog handling
...
If a request is backlogged, it's complete() handler will get called
twice: once with -EINPROGRESS, and once with the final error code.
af_alg's complete handler, unlike other users, does not handle the
-EINPROGRESS but instead always completes the completion that recvmsg()
is waiting on. This can lead to a return to user space while the
request is still pending in the driver. If userspace closes the sockets
before the requests are handled by the driver, this will lead to
use-after-frees (and potential crashes) in the kernel due to the tfm
having been freed.
The crashes can be easily reproduced (for example) by reducing the max
queue length in cryptod.c and running the following (from
http://www.chronox.de/libkcapi.html ) on AES-NI capable hardware:
$ while true; do kcapi -x 1 -e -c '__ecb-aes-aesni' \
-k 00000000000000000000000000000000 \
-p 00000000000000000000000000000000 >/dev/null & done
