2023-10-13ethernet: run callbacks for subifs too when mac changesAlexander Chernavin1-1/+10
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.

2022-08-30ethernet: refactor the redundant codeAndrew Yourtchenko1-8/+7
Following the discussion during the review of b46a4e69e5db18ef792415439d04a0ab22c59386, remove the redundant ei0. This resulted in realization that in order for this code to do anything useful, the ei must be always non-zero, so rewrite the logical condition for it. Also, make it a conjunction which seems simpler to understand. Type: improvement Change-Id: Ibd7b2a63e4aeaf97eb1a98af8e69aed2ff7dd577 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2022-08-29ethernet: fix mac address increment errorJieqiang Wang1-2/+2
Using "ip neighbor <ip-addr> <mac-addr> static count <count>" to add static ARP entries will output wrong mac addresses due to lack of big/little endian conversion. Fix this error by converting mac address from big endian to little endian before doing the self-increment.

Type: fix When the local MAC address of an interface changes the rewrite strings of all adjacency types need to be updated - this patch fixes the missing case of incomplete adjacencies. I moved the update of all adj types into the adj module, since if the complete adjs were done by the ip-neighbour module and incomplete ones by adj module, that would mean two walks of the adj DB, as it is not possible to walk only a specific type.

Fix and optimize DMAC check in ethernet-input node to utilize NIC or driver which support L3 DMAC-filtering mode so that DMAC check can be bypassed safely for interfaces/sub-interfaces in L3 mode. Checking of interface in L3-DMAC-filtering state to avoid DMAC check require the following: a) Fix interface driver init sequence for devices which supports L3 DMAC-filtering to indicate its capability and initialize interface to L3 DMAC-filtering state. b) Fix ethernet_set_flags() function and its associated callback flags_change() functions registered by various drivers in interface infra to provide proper L3 DMAC filtering status. Maintain interface/sub-interface L3 config count so DMAC checks can be bypassed if L3 forwarding is not setup on any main/sub-interfaces.

2019-11-26fib: Table ReplaceNeale Ranns2-37/+0
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.
