From 586c31f3bf04c290dc0a0de7fc91d20aa9a5ee53 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Thu, 7 Feb 2013 00:55:37 +0000 Subject: net: sctp: sctp_auth_key_put: use kzfree instead of kfree For sensitive data like keying material, it is common practice to zero out keys before returning the memory back to the allocator. Thus, use kzfree instead of kfree. Signed-off-by: Daniel Borkmann Acked-by: Neil Horman Acked-by: Vlad Yasevich Signed-off-by: David S.
