Herbert Xu 0f6bb83cb1 crypto: algif_skcipher - Fixed overflow when sndbuf is page aligned 
When sk_sndbuf is not a multiple of PAGE_SIZE, the limit tests
in sendmsg fail as the limit variable becomes negative and we're
using an unsigned comparison.

The same thing can happen if sk_sndbuf is lowered after a sendmsg
call.

This patch fixes this by always taking the signed maximum of limit
and 0 before we perform the comparison.

It also rounds the value of sk_sndbuf down to a multiple of PAGE_SIZE
so that we don't end up allocating a page only to use a small number
of bytes in it because we're bound by sk_sndbuf.
