From 76e87306c2de2a581ec939cf9c97cd18d053f90e Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Tue, 19 Feb 2008 16:12:08 -0800 Subject: [RTNL]: Add missing link netlink attribute policy definitions IFLA_LINK is no longer a write-only attribute on the kernel side and must thus be validated. Same goes for the newly introduced IFLA_LINKINFO. Fixes undefined behaviour if either of the attributes are not well formed. Signed-off-by: Thomas Graf Signed-off-by: David S.
