However, the control paths are serialised by the global per-table lock. This series converts arp_tbl and nd_tbl to per-netns table. Patch 1 ~ 2 are misc cleanup. Patch 3 ~ 6 store arp_tbl/nd_tbl to net->neigh_tables[] and remove the global neigh_tables[]. Patch 7 ~ 8 replaces the direct access to arp_tbl/nd_tbl to net->neigh_tables[] using new helpers. Patch 9 ~ 10 finally replaces the global table with per-netns table. Patch 11 cleans up unnecessary net_eq(). Note that some buggy drivers access nd_tbl without checking disable_ipv6_mod, so nd_tbl's extern definition is still left.Hi! Looks like test_neigh.sh is failing with this
Oh sorry, I had to namespacify "ntable change" for GC attributes. ip -n $ns1 ntable change Thanks !
