2018-03-14Improve l2_macs_events API to provide MAC move informationJohn Lo1-0/+1
Change mac_entry layout in l2_macs_event API message so the MAC entry can be either add, delete or move where the sw_if_index of an existing MAC entry changed. Also added a 8-bit flags field in mac_entry for any future expansion. Change-Id: I3bf9e1cf2556f2938202025a5d0772c2ce2fc99f Signed-off-by: John Lo <loj@cisco.com>
2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-0/+2
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-10-03Update L2FIB entry timestamp only if BD aging enabled (VPP-1002)John Lo1-3/+4
Change L2 learning path so it update stale timestamp in MAC entry only if aging is enabled on the BD for the MAC entry. Change-Id: I7babe986ceef3c030d8ef9185076c42b405f7b0f Signed-off-by: John Lo <loj@cisco.com>
2017-09-03Improve L2FIB PDR/NDR performance (VPP-963)John Lo1-15/+27
1. Limit MAC entry update per l2-learn call to reduce update burst when wall clock advance to the the next minute so all MAC time stamps are behind current time needing update. 2. Optimize l2-learn node fast path code sequence. 3. Invalidate cache_key when update MAC entry. 4. Change L2 learn hit counter to L2 learn hit-update counter. 5. Increase L2FIB table memory size to 512MB to fit 4M entries 6. Set MAC learn limit at 4M entries Change-Id: I3075ee8fb59645a56850126bac2e3e6d341cef4d Signed-off-by: John Lo <loj@cisco.com>
2017-08-22Increase default MAC learn limit and check it in learn-update pathJohn Lo1-0/+2
1. Increase default MAC learn limit from 1M to 8M entries. 2. Check MAC learn limit in MAC learning update path. 3. Allow disable of want_l2_macs_events to set MAC learn limit 4. Other minor cleanups Change-Id: I62438440937b5fa455e16f4a2e4d910277753395 Signed-off-by: John Lo <loj@cisco.com>
2017-08-03Add support for API client to receive L2 MAC eventsJohn Lo1-10/+20
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.

2017-07-23Improve L2 Input/Output Feature Infrastructure and UsageJohn Lo1-12/+2
Simplify L2 output feature infra to unify with L2 input feature infra using the newly improved feature bitmap mechanism. Updated all L2 features to use the more efficient infra functions. Change-Id: If8f463826b0af0717129befe92a27ea8cfc40449 Signed-off-by: John Lo <loj@cisco.com>
2017-06-27L2-LEARN:fix l2fib entry seq num not updated on hit (VPP-888)Eyal Bari1-64/+34
fixed instability in l2bd_multi_instnce test - sometimes failing with extra packets captured it appears l2-learn was not updating hit entries but rather a copy of them. if the ager did not have a chance to run before the test was running the learning cycle - entries were not updated with the packet's seq num - causing packets to flood when hitting the stale seq_num in l2-fwd - hence the extra packets fixed handling of filter entries revert workaround for instability in test Change-Id: I16d918e6310a5bf40bad5b7335b2140c2867cb71 Signed-off-by: Eyal Bari <ebari@cisco.com> (cherry picked from commit 25ff2ea3a31e422094f6d91eab46222a29a77c4b)
2017-06-19L2FWD:fix seq_num overwritten + validate l2fib entries when forwardingEyal Bari1-5/+8
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>

2017-03-28Implement MAC Flush for BD or Interface from the L2FIBJohn Lo1-1/+9
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>
