From b597ca6e8312937450dbae945f9d58c6eb35da0e Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Fri, 21 Jun 2019 17:45:21 +0200 Subject: [PATCH] ipv4/fib_frontend: Allow RTM_F_CLONED flag to be used for filtering This functionally reverts the check introduced by commit e8ba330ac0c5 ("rtnetlink: Update fib dumps for strict data checking") as modified by commit e4e92fb160d7 ("net/ipv4: Bail early if user only wants prefix entries"). As we are preparing to fix listing of IPv4 cached routes, we need to give userspace a way to request them. Signed-off-by: Stefano Brivio Reviewed-by: David Ahern Signed-off-by: David S.
