Thanks, Dave, and Eric. I ran into this 3 days ago doing some strange stuff -- I did not realize that I was compiling without -DWITHLIBSSL= where x is a positive number . Freely translated, I did not realize I was compiling ipsec_output.c with non-default options. That said, I see only one

Re: [vpp-dev] Packet loss on use of API & cmdline

With my current setup (a fairly modest 2Mpps of background traffic each way between a pair of 10G ports on an Intel X520 NIC, with baremetal Ubuntu 16, vpp 17.01 and a couple of cores per NIC), I observed a range of different packet loss scenarios: * 1K-80K packets lost if I issue any of

Re: [vpp-dev] Packet loss on use of API & cmdline

Hi Colin, Your comments were not taken as criticism ☺ constructive comments are always greatly appreciated. Apart from the non-MP safe APIs Florin mentioned, and the route add/del cases I covered, the consensus is certainly that packet loss should not occur during a ‘typical’ update and we

Re: [vpp-dev] Packet loss on use of API & cmdline

Hi neale, Thanks for the reply, and please don’t take my comments as a criticism of what I think is a great project. I’m just trying to understand whether the packet loss I’m observing when I do thinks like add new tunnels, setup routes, etc, is generally viewed as acceptable, or whether it’s

Re: [vpp-dev] Packet loss on use of API & cmdline

Hi Colin, The instances of barrier syncs you have correctly identified, occur only in the exceptional cases of route addition/deletion and not in the typical case. - adj_last_lock_gone () is called when that adjacency is no longer required, i.e. we are removing the last route, or

Which compiler are you using? Gcc-5.4 on x86_64, i686, and aarch64-le - as well as clang - are perfectly happy to compile that idiom. I don’t see it as an error. You might try combining the function declaration with the implementation, but be advised that there are numerous instances of a

Hi Florin, Thanks for the quick, and very useful reply. I’d been looking at the mp_safe flags, and had concluded that I’d need the calls I was interested in to be at least marked mp_safe. However, I was thinking that wasn’t sufficient, as it appeared that some calls marked as mp_safe invoke

Re: [vpp-dev] Packet loss on use of API & cmdline

Hi Colin, Your assumption was right. Most often than not, a binary API/CLI call results in a vlib_worker_thread_barrier_sync because most handlers and cli are not mp safe. As a consequence, vpp may experience packet loss. One way around this issue, for binary APIs, is to make sure the handler

Re: [vpp-dev] Packet loss on use of API & cmdline

I might have just missed it, but looking through the ongoing regression tests I can't see anything that explicitly tests for packet loss during CLI/API commands, so I'm wondering whether minimization of packet loss during configuration is viewed as a goal for vpp? Many/most of the real world
