* neigh: add function to look up neighbour (fdb) by ifindex, mac and vlanJonas Johansson2016-05-291-0/+26
| | | | | | | | | | | | | | | | | The rtnl_neigh_get() function can not be used to look up a fdb entry in the neigh cache. This is due to that the function searches among destination addresses (NDA_DST) and not among link layer addresses (NDA_LLADDR), which is used by fdb entries. A fdb entry can also exist in several vlans, so a vlan id parameter is also needed to find a unique entry. This commit adds a function, rtnl_neigh_get_by_vlan() which searches the neigh cache for a specific neighbour (fdb) entry by interface index, link layer address and vlan id.

* lib: update ce-mask to uint64_tDavid Ahern2016-02-121-3/+3
| | | | | | | | | | | | | | | | | | | | lib/route/link.c already defines 32 attributes which fills the current uint32_t used for ce_mask. To accommodate more attributes the mask needs to be expanded. This patch updates the definition to uint64_t. The nl_object_diff API is maintained for ABI with existing users. A new nl_object_diff64 API is added for the expanded attribute list. The MSB of the 32-bit API is used to indicate if higher order attributes had a mismatch. (Suggested by Thomas). Note that LINK_ATTR_LINK_NETNSID changes. But since the attribute flags are not public API it shouldn't be a problem. http://lists.infradead.org/pipermail/libnl/2015-December/002078.html http://lists.infradead.org/pipermail/libnl/2015-December/002083.html Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: Thomas Haller <thaller@redhat.com>
* bridge: add support for VLANsDavid Ahern2015-12-071-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | Add operation for requesting VLAN data for AF_BRIDGE and parsing of IFLA_AF_SPEC for AF_BRIDGE. VLANs are saved in a bitmap. Also add dumping of vlan info to link list and neigh list. For example: $ nl-link-list --details --family=bridge br1 ether 8e:6e:0e:86:e5:86 master br1 <broadcast,multicast,up,running,lowerup> mtu 1500 txqlen 0 weight 0 index 18 mode default carrier down bridge: pvid 1 all vlans: 1 301-400 601-610 untagged vlans: 1 bond1 ether 46:ef:e1:c9:46:fe <broadcast,multicast,master> mtu 1500 txqlen 0 weight 0 index 20 state down mode default carrier down bridge: Signed-off-by: Wilson Kok <wkok@cumulusnetworks.com> Signed-off-by: David Ahern <dsa@cumulusnetworks.com> [thaller@redhat.com: modified original patch to use ao_parse_af_full().

* link/neigh: add flags option to link and neighbor cachesDavid Ahern2015-11-191-0/+32
| | | | | | | | | | | | | Both link and neighbor cache support specify multiple groups (nl_af_group), but the alloc_cache functions for both do not set the NL_CACHE_AF_ITER flag before populating the cache so only the first group is used by default. This patch adds an API to pass in flags to make that happen and updates the nl-neigh-list command to make use of it. http://lists.infradead.org/pipermail/libnl/2015-October/001996.html Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: Thomas Haller <thaller@redhat.com>

* neigh: Remove check for AF_UNSPEC in rtnl_neigh_get()Thomas Graf2013-02-011-2/+2
| | | | | | | | | | | | | This check was introduces to not accidently return AF_BRIDGE objects to unaware API users as they do differ in structure. However, such objects are only available if explicitely requests using the NL_CACHE_AF_ITER flag or by using arg1 == AF_BRIDGE for the cache. Therefore remove this check and allow rtnl_neigh_get() to be used to fetch any neighbor object of a cache. Reported-by: Maxime Bizon <mbizon@freebox.fr> Signed-off-by: Thomas Graf <tgraf@suug.ch>

* Add master support to rtnl_neigh for AF_BRIDGE objectsroopa2012-11-151-2/+22
| | | | | | | | | | | | | | | | | | | | 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. This patch tries to get that info by a link cache lookup and adds it to the bridge neigh object Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Reviewed-by: Nolan Leake <nolan@cumulusnetworks.com> Reviewed-by: Shrijeet Mukherjee <shm@cumulusnetworks.com> Reviewed-by: Wilson Kok <wkok@cumulusnetworks.com> Signed-off-by: Thomas Graf <tgraf@suug.ch>

* Thread-safe error handlingThomas Graf2008-05-141-59/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for the interface to become more thread safe, the error handling was revised to no longer depend on a static errno and error string buffer. This patch converts all error paths to return a libnl specific error code which can be translated to a error message using nl_geterror(int error). The functions nl_error() and nl_get_errno() are therefore obsolete. This change required various sets of function prototypes to be changed in order to return an error code, the most prominent are: struct nl_cache *foo_alloc_cache(...); changed to: int foo_alloc_cache(..., struct nl_cache **); struct nl_msg *foo_build_request(...); changed to: int foo_build_request(..., struct nl_msg **); struct foo *foo_parse(...); changed to: int foo_parse(..., struct foo **); This pretty much only leaves trivial allocation functions to still return a pointer object which can still return NULL to signal out of memory. This change is a serious API and ABI breaker, sorry!
* Big routing code rework (API/ABI BREAK!)Thomas Graf2008-04-291-1/+1
| | | | | | | | | | Adds all missing routing attributes and brings the routing related code to a working state. In the process the API was broken several times with the justification that nobody is using this code yet. The changes include new example code which is also a prototype for how plain CLI tools could look like to control routes.

* Export interface to define cachesThomas Graf2007-09-171-2/+1
| | | | | | | | | | This interface was internal so far which required all code defining caches to be compiled with the sources available. In order to simplify the interface, the co_msg_parser prototype was changed to take the struct nl_parser_param directly instead of a void *. It used to be void * because the co_msg_parser was directly passed as the NL_CB_VALID callback function.
