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>
2020-09-11l2: fix null deref in l2_to_bvi()Matthew Smith1-1/+1
Type: fix Static analysis identified a possible null pointer dereference. It was introduced by a recent patch which expanded the DMAC comparison on inbound packets on a BVI interface to include any secondary MAC addresses which were added to an interface. Check if the pointer is null before dereferencing. Change-Id: Ic2afe2b062eda32977e05bf3f98d82c1fe64620c Signed-off-by: Matthew Smith <mgsmith@netgate.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.

2020-06-27l2: performance enhancement in l2inputZhiyong Yang1-80/+69
Short Load/Stores combined with prefetching in the beginning of the loop place too much pressure on AGUs and memory accesses. The patch interleaves load/store operations with computational operations to alleviate the pain point. vlib_get_buffers is also leveraged. Redefine u8 dst_and_src[12] instead of dst[6] and src[6] in struct l2input_trace_t in order to merge two copys into one.

2019-07-23api: binary api cleanupDave Barach2-5/+6
Multiple API message handlers call vnet_get_sup_hw_interface(...) without checking the inbound sw_if_index. This can cause a pool_elt_at_index ASSERT in a debug image, and major disorder in a production image. Given that a number of places are coded as follows, add an "api_visible_or_null" variant of vnet_get_sup_hw_interface, which returns NULL given an invalid sw_if_index, or a hidden sw interface: - hw = vnet_get_sup_hw_interface (vnm, sw_if_index); + hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index); if (hw == NULL || memif_device_class.index != hw->dev_class_index) return clib_error_return (0, "not a memif interface"); Rename two existing xxx_safe functions -> xxx_or_null to make it obvious what they return.

2019-07-02gbp: add anonymous l3-out external interfacesBenoît Ganne2-0/+2
So far, GBP l3-out packets classification & policy relied on programmed EP. All traffic to/from l3-out must go through a known EP. This patch introduces a new feature where l3-out next-hops are only known by their subnets (l3-out prefixes). As there are no longer known EPs to program, an interface must be configured as external anonymous l3-out. Packets classification & policy on this interface will rely on the external subnets programmed in the BD VRF. Note that contrary to all other interfaces in a GBP BD, external anonymous l3-out interfaces have BD L2 learning turned on and rely on ARP/ND.
