[vpp-dev] Forwarding packet from kernel interface to VPP srv6 policy

Hi, We have a use case where on a VPP machine, we want to generate ping request from kernel, which is then forwarded to VPP and then according to the policy configured, VPP add SRH into it and act on that packet accordingly. Can anyone please suggest how we can can achieve this?

Re: [vpp-dev] NAT ED empty users dump #nat #nat44

ED NAT no longer has “user” concept and it doesn’t differentiate one session from another. (So technically the API works just fine). Even if we wanted to recreate that information it means to build a hash of “users” on the fly for API purpose, do the dump and then throw it away. I don’t see any

Re: [vpp-dev] NAT ED empty users dump #nat #nat44

Klement, I would prefer the existing API working. I expect millions of sessions and it's clear that dumping them all is a blocker but during debug, there are not so many of them. Thanks, Alexander -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. View/Reply Online

Re: [vpp-dev] min_log2 abuse

Thanks for the patch. Anyway your code reads much more easily than the original. [Jenkins is screwed up at the moment, Dave Wallace is working on it.] We could do something like this to track down min_log2(0) calls: #if defined (count_leading_zeros) always_inline uword min_log2 (uword x) {

Re: [vpp-dev] NAT ED empty users dump #nat #nat44

Alexander, It seems that fixing existing API is a huge pain. What we could do is implement an API which dumps all the sessions and the client app could sort it out. How many sessions do you typically have? As by default APIs run in a stop-the-world state, having millions of sessions will stop

Re: [vpp-dev] NAT ED empty users dump #nat #nat44

Hello Klement, I want to list all NAT sessions. In order to do that I used to call VL_API_NAT44_USER_DUMP. After that, I had all users, and I could call VL_API_NAT44_USER_SESSION_DUMP to get sessions for every user. Now VL_API_NAT44_USER_DUMP returns nothing in ED mode and I don't know what

Re: [vpp-dev] NAT ED empty users dump #nat #nat44

Hi Alexander, thanks for your feedback. The concept of user was really used for quickly re-using existing sessions in NAT. With port-overloading, ports are no longer a precious resource and dropping “users” means not having to maintain an extra hash table. To better understand your problem,

[vpp-dev] NAT ED empty users dump #nat #nat44

Hello, As I understand the "users" concept has been removed from NAT ED and now vl_api_nat44_user_dump_t returns nothing in ED mode. vl_api_nat44_user_session_dump_t returns sessions only if you know the user you are requesting sessions for. But you can't get the user list. Therefore this

[vpp-dev] min_log2 abuse

Hi, There are few places in VPP (most notable when trying to convert a netmask into a length) that can pass 0 (zero) into min_log2 and expect to get a meaningful result. Obviously log2(0) is undefined. It turns out that this also applies to the return of min_log2. Under the hood the function
