2018-09-11L2-learn; cache prefetch fixNeale Ranns1-4/+4
the header is written (STORE) the data is only read (LOAD) Change-Id: Ia3ac0c81224a0db736c329ed3e2e55b7417f08a0 Signed-off-by: Neale Ranns <nranns@cisco.com>

2018-05-31Improve L2FIB delete entry handling and "show l2fib" CLI optionsJohn Lo1-1/+1
Improve deletion of L2FIB MAC entry using l2fib_add_del API. If sw_if_index param specified in th API is non-zero, check that its value match that of the MAC entry to proceed with deletion. Improve "show l2fib" CLI to allow display of all entries, learned entries only, or added ovia CLI/API entries only. For added entry, show "no" under the age column to indicate entry does not age.

2018-03-14Improve l2_macs_events API to provide MAC move informationJohn Lo1-1/+10
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>
2017-11-03silence l2fib_init() invalid read of size 2 found by address-sanitizerGabriel Ganne1-1/+6
l2fib_make_key() casts and reads the input 6-Bytes mac_address as u64, therefore if the mac_address is declared with 6 Bytes only, address-sanitizer rightly triggers an invalid read on the last two Bytes. However, l2fib_make_key() does a 16 bits shift to discard those 2 values, therefore, this invalid read is of no consequence (and so can be silenced safely).

2017-10-31l2fib: MAC: Fix uint64 to u8 byte arrayMohsin Kazmi1-4/+4
As per proposal on the mailing list, this patch fixes the represntation of MAC address in VPP API calls for · L2fib_add_del · L2_fib_table_details Change-Id: I31e17efd1a6314cded69666e693cb8fc33158d02 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>
2017-09-03Improve L2FIB PDR/NDR performance (VPP-963)John Lo1-1/+1
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>
2017-08-03Add support for API client to receive L2 MAC eventsJohn Lo1-6/+31
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.

2017-06-27L2-LEARN:fix l2fib entry seq num not updated on hit (VPP-888)Eyal Bari1-0/+13
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 Bari1-0/+24
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 Lo1-16/+23
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>
