2017-08-03Add support for API client to receive L2 MAC eventsJohn Lo1-31/+6
Added APIs want_l2_macs_events and l2_macs_event to allow an API client to receive notification events from VPP for MAC learned or aged in L2FIB. Only one API client is allowed for L2 MAC events. The want_l2_macs_events API allow caller to specify MAC learn limit, event scan delay and max number of MACs that can be included in a event message. These parameters should be choosen properly as to not have too many MAC events sent by VPP and overwhelm the API share memory. They can all be left as 0's so VPP will setup reasonable defaults which are: 1000 learn limit, 100 msec scan delay and 100 MACs per event message. If want_l2_macs_events is never called, VPP learning and aging should behave as before except that MAC entries provisioned by API or CLI will not be aged, even if it is not set as static_mac. These non static MACs, however, can be overwritten by MAC learning on a MAC move as a leared MAC. Only learned MACs are subject to aging.

2017-06-19L2FWD:fix seq_num overwritten + validate l2fib entries when forwardingEyal Bari1-3/+2
l2_classify memeber table_index was overlaid over l2.l2fib_seq_num which over written when table_index gets initialized in l2_input_classify solved by overlaying both table_index and opaque_index as only one is used seperated l2fib seq num from l2_input configs for better handling of theoretical ABA issue where an entry for a deleted interface is considered valid by the ager because a different interface with same sw_if_index and seq_num was created before the ager got a chance to delete Change-Id: I7b0eeded971627406f1c80834d7e02c0ebe62136 Signed-off-by: Eyal Bari <ebari@cisco.com>
2017-05-19Enforce Bridge Domain ID range to match 24-bit VNI rangeJohn Lo1-6/+11
Enforce bridge domain ID range to allow a maximum value of 16M which matches the range of 24-bit VNI used for virtual overlay network ID. Fix "show bridge-domain" output to allow full 16M BD ID range to be displayed using 8-digit spaces. Change-Id: I80d9c76ea7c001bcccd3c19df1f3e55d2970f01c Signed-off-by: John Lo <loj@cisco.com>
2017-05-05Fix L2FIB learn counter and memory cleanup of mac_by_ip6 hash tableJohn Lo1-2/+11
Fix global_learn_count to be incremented or decremented by add and deletion of non-static MAC entries from L2FIB only. Without this fix, the counter may reach the threshold of 1M and stop MAC leanring even though number of MAC entries in L2FIB is less than the threshold. Cleanup indirect hash key memory used by mac_by_ip6 hash table on BD deletion. Change-Id: I13986c4e6304c7956122520dd3f83d6bb6e65a15 Signed-off-by: John Lo <loj@cisco.com>

2017-05-02Prevent Bridge Domain operations on BD 0.Jon Loeliger1-1/+44
The default bridge domain, 0, is created automatically with static features. It should be modified by neither the CLI nor the API. So add tests for, and reject any operation on BD 0. The new API error message BD_NOT_MODIFIABLE is returned in such cases. Change-Id: Iaf3dd80c4f43cf41689ca55756a0a3525420cd12 Signed-off-by: Jon Loeliger <jdl@netgate.com>

2017-03-28Implement MAC Flush for BD or Interface from the L2FIBJohn Lo1-15/+26
Allow non-static MACs in the L2FIB which is associated with an interface or a bridge domain (BD) be flushed. MAC flush are initiated automatically when an interface is removed from a BD or when a BD is deleted. MAC flush can also be invoked manually via the following CLI: l2fib mac-flush interface <if-name> l2fib mac-flush bridge-domain <bd-id> Change-Id: Ie33243622834810a765f48ebcd22bdb8e8fc87a4 Signed-off-by: John Lo <loj@cisco.com>
2017-03-02bridge domain: fix members reordered when removingEyal Bari1-1/+1
since adding support for multicast vxlan flooding (flood class tunnel master) correct flood functionality depends on the order of the memebers vector solved by using vec_delete instead of vec_del1 which swaps members before deleting the last element Change-Id: I234f218d49172b4142c567db9699a5cb274e4a66 Signed-off-by: Eyal Bari <ebari@cisco.com>
