From 70a269e6c9c9b38b1a37dce068c59e9a912f8578 Mon Sep 17 00:00:00 2001 From: Benjamin Thery Date: Thu, 22 Jan 2009 04:56:15 +0000 Subject: netns: ipmr: allocate mroute_socket per-namespace. Preliminary work to make IPv4 multicast routing netns-aware. Make IPv4 multicast routing mroute_socket per-namespace, moves it into struct netns_ipv4. At the moment, mroute_socket is only referenced in init_net. Signed-off-by: Benjamin Thery Signed-off-by: David S.

Declare variable cache_resolve_queue_len per-namespace: move it into struct netns_ipv4. This variable counts the number of unresolved cache entries queued in the list mfc_unres_queue. This list is kept global to all netns as the number of entries per namespace is limited to 10 (hardcoded in routine ipmr_cache_unresolved). Entries belonging to different namespaces in mfc_unres_queue will be identified by matching the mfc_net member introduced previously in struct mfc_cache. Keeping this list global to all netns, also allows us to keep a single timer (ipmr_expire_timer) to handle their expiration. In some places cache_resolve_queue_len value was tested for arming or deleting the timer. These tests were equivalent to testing mfc_unres_queue value instead and are replaced in this patch. At the moment, cache_resolve_queue_len is only referenced in init_net. Signed-off-by: Benjamin Thery Signed-off-by: David S.
