3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mathias Krause <minipli@xxxxxxxxxxxxxx> [ Upstream commit 6865d1e834be84ddd5808d93d5035b492346c64a ] When filling the netlink message we miss to wipe the pad field, therefore leak one byte of heap memory to userland. Fix this by setting pad to 0. Signed-off-by: Mathias Krause <minipli@xxxxxxxxxxxxxx> Signed-off-by: David S.
