crypto: algif - avoid excessive use of socket buffer in skcipher
commit e2cffb5f493a8b431dc87124388ea59b79f0bccb upstream.
On archs with PAGE_SIZE >= 64 KiB the function skcipher_alloc_sgl()
fails with -ENOMEM no matter what user space actually requested.
This is caused by the fact sock_kmalloc call inside the function tried
to allocate more memory than allowed by the default kernel socket buffer
size (kernel param net.core.optmem_max).
