* ipv6: ip6mr: support multiple tablesPatrick McHardy2010-05-111-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: remove net pointer from struct mfc6_cachePatrick McHardy2010-05-111-15/+0
| | | | | | | | Now that cache entries in unres_queue don't need to be distinguished by their network namespace pointer anymore, we can remove it from struct mfc6_cache add pass the namespace as function argument to the functions that need it. Signed-off-by: Patrick McHardy <kaber@trash.net>

* net: Make setsockopt() optlen be unsigned.David S. Miller2009-09-301-2/+2
| | | | | | | | | | | | This provides safety against negative optlen at the type level instead of depending upon (sometimes non-trivial) checks against this sprinkled all over the the place, in each and every implementation. Based upon work done by Arjan van de Ven and feedback from Linus Torvalds. Signed-off-by: David S. Miller <davem@davemloft.net>
* make exported headers use strict posix typesArnd Bergmann2009-03-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | A number of standard posix types are used in exported headers, which is not allowed if __STRICT_KERNEL_NAMES is defined. In order to get rid of the non-__STRICT_KERNEL_NAMES part and to make sane headers the default, we have to change them all to safe types. There are also still some leftovers in reiserfs_fs.h, elfcore.h and coda.h, but these files have not compiled in user space for a long time. This leaves out the various integer types ({u_,u,}int{8,16,32,64}_t), which we take care of separately.

* netns: ip6mr: enable namespace support in ipv6 multicast forwarding codeBenjamin Thery2008-12-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This last patch makes the appropriate changes to use and propagate the network namespace where needed in IPv6 multicast forwarding code. This consists mainly in replacing all the remaining init_net occurences with current netns pointer retrieved from sockets, net devices or mfc6_caches depending on the routines' contexts. Some routines receive a new 'struct net' parameter to propagate the current netns: * ip6mr_get_route * ip6mr_cache_report * ip6mr_cache_find * ip6mr_cache_unresolved * mif6_add/mif6_delete * ip6mr_mfc_add/ip6mr_mfc_delete * ip6mr_reg_vif All the IPv6 multicast forwarding variables moved to struct netns_ipv6 by the previous patches are now referenced in the correct namespace. Changelog: ========== * Take into account the net associated to mfc6_cache when matching entries in mfc_unres_queue list. * Call mroute_clean_tables() in ip6mr_net_exit() to free memory allocated per-namespace. * Call dev_net_set() in ip6mr_reg_vif() to initialize dev->nd_net correctly.

* netns: ip6mr: store netns in struct mfc6_cacheBenjamin Thery2008-12-101-0/+15
| | | | | | | | | | | | | | | | | | | | This patch stores into struct mfc6_cache the network namespace each mfc6_cache belongs to. The new member is mfc6_net. mfc6_net is assigned at cache allocation and doesn't change during the rest of the cache entry life. This will help to retrieve the current netns around the IPv6 multicast forwarding code. At the moment, all mfc6_cache are allocated in init_net. Changelog: ========== * Use write_pnet()/read_pnet() to set and get mfc6_net. Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* netns: ip6mr: allocate mroute6_socket per-namespace.Benjamin Thery2008-12-101-2/+6
| | | | | | | | | | | | Preliminary work to make IPv6 multicast forwarding netns-aware. Make IPv6 multicast forwarding mroute6_socket per-namespace, moves it into struct netns_ipv6. At the moment, mroute6_socket is only referenced in init_net. Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Unbreak userspace usage of linux/mroute.hDavid S. Miller2008-08-291-0/+1
| | | | | | | | | | | | | | | | | Nothing in linux/pim.h should be exported to userspace. This should fix the XORP build failure reported by Jose Calhariz, the debain package maintainer. Nothing originally in linux/mroute.h was exported to userspace ever, but some of this stuff started to be when it was moved into this new linux/pim.h, and that was wrong. If we didn't provide these definitions for 10 years we can reasonably expect that applications defined this stuff locally or used GLIBC headers providing the protocol definitions. And as such the only result of this can be conflict and userland build breakage. Signed-off-by: David S. Miller <davem@davemloft.net>
