| | | | | | | | | | | | | This provides support for the new bridging attributes provided in IFLA_PROTINFO while maintaining backwards compatibility with older kernels. A set of new API functions are exported to access the bridging information. rtnl_link_bridge_has_ext_info() can be used to check whether a bridge object has been constructed based on the newly available attributes or the old message format.

* No longer install module API headersThomas Graf2013-01-231-6/+6
| | | | | | | | | | | | | | | Various header files providing an API to implement own cache and object types or implement link types have been available in the past. Their API is marked unstable in the documentation and nobody is using them so far. Technically they have been causing ABI breakages in at least two 3.2.x releases. In order to avoid future accidental breakage, no longer install these and require module developers to clone the git tree and build modules off the git tree directly to make sure that the API is unstable at this point.

* link af ops: Add new ao_compare op to compare link af_dataroopa2013-01-121-0/+13
| | | | | | | | | | | | | | This patch adds new operation to compare link af_data. ao_compare is similar to object oo_compare operation. This op can be used when two links are compared for their af data. It takes two link objects in question, an object specific bitmask defining which attributes should be compared and flags to control the behaviour. The function must return a bitmask with the relevant bit set for each attribute that mismatches. Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: Thomas Graf <tgraf@suug.ch>

* Bug Fix: Add new fill socket to cache managerroopa2012-11-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new socket to cache manager to request fill's on. cache manager today uses cm_sock to request dump from the kernel. It also listens to netlink async events on the same sock. The problem with this is that when libnl is waiting to process the response to get dump request sent to the kernel during fill, it may receive an async event, resulting in libnl complaining about unexpected msg This is usually reproducible when there is heavy netlink async event traffic during nl_cache_mngr_add. This patch adds a new cm_sync_sock to use for fill during cache manager add cache. The other option is to provide an api to set the cm_sync_sock. But since this is a bug fix its probably better to fix the cache manager add api like this patch does. Please suggest otherwise.

| | | | | | | | | | | | | | | | | | | | AF_BRIDGE neigh objects can be uniquely identified by the family, lladdr and bridge ifindex. This patch adds bridge ifindex to AF_BRIDGE neigh objects. Things will be ok even without this patch with just family and lladdr if we assume that we will have unique lladdr's accross bridges in a system. Kernel does not send the bridge ifindex in the AF_BRIDGE fdb/neigh message.

* New cache manager add cache apiroopa2012-11-121-0/+3
| | | | | | | | | | | | | | | | | | | This patch is an attempt to add a new nl_cache_mngr_add_cache api to allow adding an existing cache to cache manager. Since the new api is similar to nl_cache_mngr_add except for allocating the cache, the patch moves most of the nl_cache_mngr_add code to nl_cache_mngr_add_cache and changes nl_cache_mngr_add to call nl_cache_mngr_add_cache. One use case for this api as pointed out by thomas would be to set cache flags before associating the cache with a cache manager. nl_cache_alloc_name("route/link", &cache); nl_cache_set_flags(cache, NL_CACHE_AF_ITER); nl_cache_mngr_add_cache(mngr, cache, ...); Signed-off-by: Thomas Graf <tgraf@suug.ch>
