-Subject: [PATCH] net: ipv4: fix regression in local-broadcast routes
-
-Commit 9e30ecf23b1b ("net: ipv4: fix incorrect MTU in broadcast routes")
-introduced a regression where local-broadcast packets would have their
-gateway set in __mkroute_output, which was caused by fi = NULL being
-removed.
-
-Fix this by resetting the fib_info for local-broadcast packets. This
-preserves the intended changes for directed-broadcast packets.
-
-Cc: stable@vger.kernel.org
