From d30045a0bcf144753869175dd9d840f7ceaf4aba Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 23 Mar 2007 11:37:48 -0700 Subject: [NETLINK]: introduce NLA_BINARY type This patch introduces a new NLA_BINARY attribute policy type with the verification of simply checking the maximum length of the payload. It also fixes a small typo in the example. Signed-off-by: Johannes Berg Signed-off-by: Thomas Graf Signed-off-by: David S.
