From 71944eb54288509c7c19ac54b485ac774c8253fe Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Wed, 17 Oct 2018 22:34:34 +0300 Subject: [PATCH] net: ipmr: fix unresolved entry dumps [ Upstream commit eddf016b910486d2123675a6b5fd7d64f77cdca8 ] If the skb space ends in an unresolved entry while dumping we'll miss some unresolved entries. The reason is due to zeroing the entry counter between dumping resolved and unresolved mfc entries. We should just keep counting until the whole table is dumped and zero when we move to the next as we have a separate table counter.
