2021-02-09l2: crash on l2_input_is_xconnectSteven Luong1-10/+8
Running vpp without any interface configured and then invoking the binary-api l2_xconnect_dump causes vpp to crash in l2_input_is_xconnect due to l2input_main.configs has no memory allocated to it, not even for the local interface which exists all the times. The reason that l2input_main.configs has no memory allocated to it was due to gerrit patch 29232 which took out a line in l2input_init /* Create the config vector */ vec_validate (mp->configs, 100); The fix is to iterate through l2input_main.configs for each interface in l2 to call l2_input_is_xconnect when dumping l2_xconnect interfaces.

There no longer a need for a separate _test.c.

2020-10-12l2: mark l2 fib uninitialized after clearingMatthew Smith1-0/+2
Type: fix After clearing the l2fib with 'vppctl clear l2fib', a SEGV occurs the next time a MAC address is learned. In l2fib_clear_table(), the l2fib bihash is freed and then l2fib_table_init() is called to reinitialize it. l2fib_table_init() will not do anything if l2fib_main.mac_table_initialized is set to 1. Reset the value of l2fib_main.mac_table_initialized to 0 before calling l2fib_table_init(). Change-Id: I87f1a3f9a46c951f36c1c0a5ab795b0ec08c81a8 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2020-09-14l2: allocate l2fib only when neededDamjan Marion4-10/+90
Currently l2 fib allocates 512MB hash table unconditionally on startup. This patch postpones table creation up to the point where first interface is put into l2 mode or mac entry is added. In addition it reduces default table size to 128MB and increases number of buckets 4 times. This default setting should be enough to keep 1M mac entries. Also, new startup.conf section is added which allows user to change memory and bucket size. .i.e: l2fib { table-size 512M num-buckets 524288 } Type: improvement Change-Id: I2a29209aa3545181f0087544c97a54d8157b6ec5 Signed-off-by: Damjan Marion <damarion@cisco.com>

2020-09-09l2: check secondary macs on BVI interfaceMatthew Smith1-2/+35
Type: fix VRRP cannot be used on a BVI interface currently because packets sent to the virtual mac address of the VR fail the destination mac check in l2_to_bvi(). Apparently people want to use VRRP on BVI interfaces, so update the check in l2_to_bvi() so that it will check any secondary mac addresses which have been added to the ethernet interface if the destination mac address does not match the primary mac address for the interface. An equivalent check is already done in ethernet_input_inline() for L3 interfaces which are in promiscuous mode.
