Hi,
I am using VPP21.06
In vlib_buffer_advance there is the following assert --
ASSERT ((b->flags & VLIB_BUFFER_NEXT_PRESENT) == 0 ||
b->current_length >= VLIB_BUFFER_MIN_CHAIN_SEG_SIZE);
The above is problematic as I have a usecase where I construct a chained packet.
The first packet in the chain is containing just an ip4/udp/gtp header
and the second packet in the chain is an IP4 packet of arbitrary
length -- you can see that I am trying to wrap the packet into gtp via
chaining.
As a result this assert hits and brings the house down.
My usecase works fine when I use the non-debug build of VPP.
Perhaps this assert should be removed ?
Regards
-Prashant
