Hi Akshaya, Yes it is, via app namespaces. You can configure application namespaces via binary api or “app ns” cli. For instance: app ns id secret sw_if_index The secret is a shared secret between vpp and the app while the sw_if_index is the index of an interface that ‘supports’ the names

Re: [vpp-dev] VLIB_BUFFER_TOTAL_LENGTH_VALID set but invalid total_length_not_including_first_buffer

Hi Yoann, Shouldn’t the clone code only read s->total_length_not_including_first_buffer only if VLIB_BUFFER_NEXT_PRESENT flag is set for s? I’m thinking about this line in particular: d->total_length_not_including_first_buffer = s->total_length_not_including_first_buffer + s->cur

Re: [vpp-dev] ONE topology not working #vnet #vpp

Hi Saurabh, Glad to see you’re interested in LISP! As the error lower suggests, you first need to enable the lisp code. You can achieve this by doing: “one enable". Note that although “lisp enable” would also have the same result, going forward we plan to deprecate the “lisp” apis in favor of

Re: [vpp-dev] vcl error

Hi Terry, From the errors you’re seeing, I can only guess you have configured vcl to attach to the host stack using a local scope. Do you have vcl.conf configured with “app-scope-local” or have you exported VCL_APP_SCOPE_LOCAL environment variable? If yes, try disabling them. If neither global

Re: [vpp-dev] Regarding VPP TCP Stack usage

Prashant, Dave is exactly right. If you still want to try out the LDP layer, I wouldn’t set a global LD_PRELOAD variable because that will end up preloading all the applications and, inevitably, to some unsupported usage patterns and crashes. Instead, start only your app with LD_PRELOAD set, s

Re: [vpp-dev] Control TCP_NODELAY and TCP_QUICKACK per session

Hi Tomasz, We actually have both hardwired to “on" in the the stack. The reason why they’re on VCL’s list is because we don’t have APIs to inspect/modify them. There’s no plan to support Nagle’s algorithm but we should support at some point adaptive acks. Also, in case you haven’t been follo

Re: [vpp-dev] About the vppcom_epoll_wait function in vcl

Hi Yalei, Are you testing with master latest? Yes, blocking mode will be properly supported. The reason it won’t block now is because we need to poll multiple message queues (vpp’s and cut-through sessions) and -1 is not interpreted as a large number. This will be fixed once we switch from con

Hi Yalei, I guess there’s two solutions to that. Set min_chunk to something like clib_min (16 << 10, fifo_size/2) or remove min_chunk entirely. I’m fine with either of those. Feel free to push a patch! Thanks, Florin > On Aug 8, 2018, at 12:17 AM, 汪亚雷 wrote: > > Hi Florin, > > These days

Hi Yalei, You have an example of how to write a vcl.conf file in vcl/vcl_test.conf. It’s just an example, so if you want to try out eventfd, here’s what I’ve been recently using: vcl { rx-fifo-size 400 tx-fifo-size 400 app-scope-local app-scope-global api-socket-name /run/vpp

Hi Ping, Just from this, I can’t tell precisely what the issue is. Once the test hangs, do “show session verbose 2” and you should get the detailed status of the sessions that froze. I’ll take a look at those once I’m back in the office. Retransmissions should work fine but one never knows. On
