From 222e83d2e0aecb6a5e8d42b1a8d51332a1eba960 Mon Sep 17 00:00:00 2001 From: Hannes Frederic Sowa Date: Sat, 19 Oct 2013 21:48:58 +0200 Subject: tcp: switch tcp_fastopen key generation to net_get_random_once Changed key initialization of tcp_fastopen cookies to net_get_random_once. If the user sets a custom key net_get_random_once must be called at least once to ensure we don't overwrite the user provided key when the first cookie is generated later on.
