[vpp-dev] UDP multithreading error

[nengjie wang]

The attachment is my server program.

My VPP version is 22.06. When I start this server by LDP and send a request
to this server, the server will have a direct segment error. Two threads
share an event queue, resulting in an event queue crash. Can you tell me if
LDP does not support this use?

In addition, I noticed that there is a configuration item called ‘muti
thread workers’ in the VCL configuration file. When this configuration is
turned on, the program can not receive RPC response. Is it suitable for me
to use this configuration item in this case?

Hi Laszlo,

Thanks but the link points to gerrit.nordix.org which is not fd.io gerrit. If 
we want us to review/merge something, please submit a patch on 
https://gerrit.fd.io/ 😊

Best
ben

Hello devs,

It's just a notice, that I reworked a minor fix for build on openSUSE. Excuse 
me if I confused the reviewer with my updates on this commit.

[vpp-dev] lpm table api?

[hemant via lists.fd.io]

I see vpp uses a lpm table for fib_entry_t. Is any api available to create a
lpm table in a plugin?

Hi, 

Just tested on master and this seems to work fine after a few app fixes. Having 
said that, I would recommend you build vcl native apps and register multiple 
workers for better performance.

Comments:
- make sure sockets are not blocking otherwise there’s a good change that only 
one of the threads will output something
- only print a message if data was received

See diff here [1].  

Example output, with 2 clients (c1 and c2) and updated ips.
