From 011f175428d46461f94a65dacb9a416529d08dda Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sun, 28 Jul 2019 00:37:26 +0100 Subject: [PATCH] rocker: fix memory leaks of fib_work on two error return paths Currently there are two error return paths that leak memory allocated to fib_work. Fix this by kfree'ing fib_work before returning. Addresses-Coverity: ("Resource leak") Fixes: 19a9d136f198 ("ipv4: Flag fib_info with a fib_nh using IPv6 gateway") Fixes: dbcc4fa718ee ("rocker: Fail attempts to use routes with nexthop objects") Signed-off-by: Colin Ian King Reviewed-by: David Ahern Acked-by: Jiri Pirko Signed-off-by: David S.
