tcp: md5: use sock_kmalloc() to limit md5 keys There is no limit on number of MD5 keys an application can attach to a tcp socket. This patch adds a per tcp socket limit based on /proc/sys/net/core/optmem_max With current default optmem_max values, this allows about 150 keys on 64bit arches, and 88 keys on 32bit arches.
