2017-08-13default update adjacency function deos not return multicast adjacencyNeale Ranns1-6/+40
by not returning a multicast adjacency type when requested, but instead returning a nbr type, the mcast adj was never correctly deleted. hence when reused the adjacency object was not realocated from the pool and when it was freed a second time a crash occured.

2017-08-11acl-plugin: add the debug CLI to show macip ACLs and where they are applied ↵Andrew Yourtchenko1-0/+76
(VPP-936) When looking at resource utilisation, it is useful to understand the interactions between the acl-plugin and the rest of VPP. MACIP ACLs till now could only be dumped via API, which is tricky when debugging. Add the CLIs to see the MACIP ACLs and where they are applied.

2017-08-10acl-plugin: hash lookup bitmask not cleared when ACL is unapplied from ↵Andrew Yourtchenko3-4/+31
interface (VPP-935) The logic in hash ACL bitmask update was using the vector of ACLs applied to the interface to rebuild the hash lookup mask. However, in transient cases (like doing group manipulation with hash ACLs), that will not hold true. Thus, make a local copy of for which ACL indices the hash_acl_apply was called previously, and maintain that one local to the hash_lookup.c file logic.

As far as the svm fifo code is concerned, it's OK to set fifo->nitems anywhere in the interval: [0, 1<<(fifo->freelist_index) + FIFO_SEGMENT_MIN_FIFO_SIZE] It's unlikely that setting nitems below the path MTU will work out very well...

traffic (VPP-910/VPP-929) The commit fixing the VPP-910 and separating the memory operations into separate heaps has missed setting the MHEAP_FLAG_THREAD_SAFE, which quite obviously caused the issues in the multithread setup. Fix that. Also, add the debug CLIs "set acl-plugin heap {main|hash} {validate|trace} {1|0}" to toggle the memory instrumentation, in case we ever need it in the future.

2017-08-08acl-plugin: rework the optimization 7383, fortify acl-plugin memory behavior ↵Andrew Yourtchenko5-150/+289
(VPP-910) The further prolonged testing from testbed that reported VPP-910 has uncovered a couple of deeper issues with optimization from 7384, and the usage of subscripts rather than vec_elt_at_index() allowed to hide a couple of further errors in the code. Also, the current acl-plugin behavior of using the global heap for its dynamic data is problematic - it makes the troubleshooting much harder by potentially spreading the problem around. Based on this experience, this commits makes a few changes to fix the issues seen, also improving the serviceability of the acl-plugin code for the future: - Use separate mheaps for any ACL-related control plane operations and separate for the hash lookup datastructures, to compartmentalize any memory-related issues for the ACL plugin. - Ensure vec_elt_at_index() usage throughout the hash_lookup.c file. - Use vectors rather than raw memory for storing the "ordinary" ACL rules. - Rework the optimization from 7384 to use a separate tail pointer rather than overloading the "prev" field. - Make get_session_ptr() more conservative and adjust is_valid_session_ptr accordingly Change-Id: Ifda85193f361de5ed3782a4acd39622bd33c5830 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> (cherry picked from commit bd9c5ffe39e9ce61db95d74d150e07d738f24da1)

despite VPP DHCP client setting neither ciaddr nor giaddr and setting the broadcast bit (see RFC 2131 section 4.1) some DHCP servers will still send a unicast DCHPACK.

2017-08-03Add support for API client to receive L2 MAC eventsJohn Lo11-173/+605
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.
