* ipv6: ip6mr: support multiple tablesPatrick McHardy2010-05-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT6_TABLE. The table number is stored in the raw socket data and affects all following ip6mr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT) is created with a default routing rule pointing to it. Newly created pim6reg devices have the table number appended ("pim6regX"), with the exception of devices created in the default table, which are named just "pim6reg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip -6 mrule add iif eth0 lookup 123 # ip -6 mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net>

* ipv6: ip6mr: move unres_queue and timer to per-namespace dataPatrick McHardy2010-05-111-0/+2
| | | | | | | | | | | | | The unres_queue is currently shared between all namespaces. Following patches will additionally allow to create multiple multicast routing tables in each namespace. Having a single shared queue for all these users seems to excessive, move the queue and the cleanup timer to the per-namespace data to unshare it. As a side-effect, this fixes a bug in the seq file iteration functions: the first entry returned is always from the current namespace, entries returned after that may belong to any namespace.

* netns: embed ip6_dst_ops directlyAlexey Dobriyan2009-09-011-1/+2
| | | | | | | | | | | | | | | | | struct net::ipv6.ip6_dst_ops is separatedly dynamically allocated, but there is no fundamental reason for it. Embed it directly into struct netns_ipv6. For that: * move struct dst_ops into separate header to fix circular dependencies I honestly tried not to, it's pretty impossible to do other way * drop dynamical allocation, allocate together with netns For a change, remove struct dst_ops::dst_net, it's deducible by using container_of() given dst_ops pointer.

* netns: ip6mr: declare counter cache_resolve_queue_len per-namespaceBenjamin Thery2008-12-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Preliminary work to make IPv6 multicast forwarding netns-aware. Declare variable cache_resolve_queue_len per-namespace: moves it into struct netns_ipv6. 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 ip6mr_cache_unresolved). Entries belonging to different namespaces in mfc_unres_queue will be identified by matching the mfc_net member introduced previously in struct mfc6_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 <benjamin.thery@bull.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* [NETNS][FRAGS]: Isolate the secret interval from namespaces.Pavel Emelyanov2008-01-281-1/+0
| | | | | | | | | | | | Since we have one hashtable to lookup the fragment, having different secret_interval-s for hash rebuild doesn't make sense, so move this one to inet_frags.

| | | | | | | | | | | | | | | | Since fragment management code is consolidated, we cannot have the pointer from inet_frag_queue to struct net, since we must know what king of fragment this is. So, I introduce the netns_frags structure. This one is currently empty, but will be eventually filled with per-namespace attributes. Each inet_frag_queue is tagged with this one. The conntrack_reasm is not "netns-izated", so it has one static netns_frags instance to keep working in init namespace. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | This is the core. Declare and register the pernet subsys for addrconf. The init callback the will create the devconf-s. The init_net will reuse the existing statically declared confs, so that accessing them from inside the ipv6 code will still work. The register_pernet_subsys() is moved above the ipv6_add_dev() call for loopback, because this function will need the net->devconf_dflt pointer to be already set.

| | | | | | | | | | | | | The ip6_frags is moved to the network namespace structure.
