[vpp-dev] Regarding assert in vlib_buffer_advance

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

Yes we are aware of it, still working on the correct fix though. In the meantime you can try to apply https://gerrit.fd.io/r/c/vpp/+/32765 which should workaround that for now. Best ben > -Original Message- > From: chetan bhasin > Sent: lundi 6 septembre 2021 14:21 > To: Benoit Ganne

Hi, I am using VPP21.06. I have successfully created an IPSec tunnel between VPP and a Strong Swan peer. Packets from VPP are going into ESP towards the peer, the peer is responding back with ESP as well (inner cleartext packets are ICMP) Now then, I have a node of my own which is sitting on the
