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.

2019-03-21BVI InterfaceNeale Ranns1-0/+5
a new dedicated BVI interface as opposed to [re]using a loopback. benefits: - removes ambiguity over the purpose of a loopback interface - TX node dedicated to BVI only functions. Change-Id: I749d6b38440d450ac5b909a28053c75ec9df946a Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-01-30Use IP and MAC API types for neighborsNeale Ranns1-1/+1
use address_t and mac_address_t for IPv6 and ARP entries and all other API calls in ip.api aprat from the route ones, that will follow in a separate commit Change-Id: I67161737c2184d3f8fc1e79ebd2b55121c5b0191 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-07-14Introduce l{2,3,4}_hdr_offset fields in the buffer metadataDamjan Marion1-1/+1
To save space in the first cacheline following is changed: - total_length_not_including_first_buffer moved to the 2nd cacheline. This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists. In case we need more we can store index in the 2nd cachelin Change-Id: Ic8521350819391af470d31d3fa1013e67ecb7681 Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-04-06Use thread local storage for thread indexDamjan Marion1-1/+1
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
