2024-05-08ethernet: check destination mac for L3 in ethernet-input nodeSteven Luong1-0/+1
When the NIC does not support mac filter, we rely on ethernet-input node to do the destination mac check, ie, when the interface is in L3, the mac address for the packet must be the mac address of the interface where the packet arrives. This works fine in ethernet-input node when all packets in the frame might have different interfaces, ie, ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is not set in the frame. However, when all packets are having the same interface, ETH_INPUT_FRAME_F_SINGLE_SW_IF_ID is set, ethernet-input node goes through the optimized routine eth_input_single_int -> eth_input_process_frame. That is where dmac check has a bug when all packets in the frame are either, ip4, ip6, or mpls without vlan tags. Because without vlan tags, the code handles all packets in fast path and ignores dmac check. With vlan tags, the code goes to slow path where dmac check is handled properly. The fix is to check if we have a bad dmac in the fast path and force the code to go to slow path which will handle dmac check properly. Also do a wholesale correction on all the testcases which do not use the proper dmac when sending L3 packets.

2023-10-25fib: only update glean for interface if necessaryMatthew Smith1-9/+12
Type: improvement If an interface address is added, the glean adjacency for it's covering prefix is updated with that address. In the case of multiple addresses within the same prefix being added, the most recently added one will end up being used as the sender protocol address for ARP requests. Similar behavior occurs when an interface address is deleted. The glean adjacency is updated to some appropriate entry under it's covering prefix. If there were multiple interface addresses configured, we may update the address on the adjacency even though the address currently in use is not the one being deleted. Add a new value PROVIDES_GLEAN to fib_entry_src_flag_t. The flag identifies whether a source interface entry is being used as the address for the glean adjacency for the covering prefix. Update logic so that the glean is only updated on adding an interface address if there is not already a sibling entry in use which has the flag set. Also, only update the glean on deleting an interface address if the address being deleted has the flag set. Also update unit test which validates expected behavior in the case where multiple addresses within a prefix are configured on an interface.

2023-10-13ethernet: run callbacks for subifs too when mac changesAlexander Chernavin1-3/+103
When MAC address changes for an interface, address change callbacks are executed for it. In turn adjacencies register a callback for MAC address changes to be able to update their rewrite strings accordingly. Subinterfaces inherit MAC address from the parent interface. When MAC address of the parent interface changes, it also implies MAC address change for its subinterfaces. The problem is that this is currently not considered when address change callbacks are executed. After MAC address change on the parent interface, packets sent from subinterfaces might have wrong source MAC address as the result of stale adjacencies. For example, ARP messages might be sent with the wrong (previous) MAC address and address resolution will fail. With this fix, when address change callbacks are executed for an interface, they will be also executed for its subinterfaces. And adjacencies will be able to update accordingly.

2022-05-10tests: replace pycodestyle with blackKlement Sekera1-1000/+1215
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.

2019-06-18fib: fib api updatesNeale Ranns1-7/+7
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
