From: Harald Welte Date: Sun, 31 Jul 2005 00:44:07 +0000 (-0700) Subject: [NETFILTER] Inherit masq_index to slave connections X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1f494c0e040b001cf844280910d04ba7ebdc2898;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [NETFILTER] Inherit masq_index to slave connections masq_index is used for cleanup in case the interface address changes (such as a dialup ppp link with dynamic addreses). Without this patch, slave connections are not evicted in such a case, since they don't inherit masq_index. Signed-off-by: Harald Welte Signed-off-by: David S.
