Description

Hello everyone,
I am trying to attach two xdp programs to the same interface with BCC.
The two programs stay attached but only the last one loaded works.

Does BCC not support multiple attachments?
If so, would there be another way to use BCC and attach multiple programs to the same interface?

I am using kernel version 6.1.65-1
Thanks!

Research direction

Start by reviewing BCC's XDP attachment behavior and the kernel 6.1.65-1 environment described in the report. Reproduce attaching two XDP programs to one interface and determine whether multiple attachments are supported; done means documenting the behavior and identifying a supported usage path or a clearly scoped implementation need.
