…7) (#18416) Currently, whenever isc-dhcp-relay forwards a packet upstream, internally, it will try to send it on a "fallback" interface. My understanding is that this isn't meant to be a real interface, but instead is basically saying to use Linux's regular routing stack to route the packet appropriately (rather than having isc-dhcp-relay specify specifically which interface to use). The problem is that on systems with a weak CPU, a large number of interfaces, and many upstream servers specified, this can introduce a noticeable delay in packets getting sent. The delay comes from trying to get the ifindex of the fallback interface. In one test case, it got to the point that only 2 packets could be processed per second. Because of this, dhcrelay will easily get backlogged and likely get to a point where packets get dropped in the kernel. Fix this by adding a check saying if we're using the fallback interface, then don't try to get the ifindex of this interface. We're never going to have an interface named this in SONiC.

Why I did it deb11u1 is deprecated. Use deb11u2 instead. Other branches are not impacted, because their reproducible build version files are up to date. Work item tracking Microsoft ADO (number only): 26964185 How I did it How to verify it
