aya: add feature probing for program and map type #1063

Open tyrone-wu opened 1 month ago

tyrone-wu commented 1 month ago

Add API for detecting whether kernel supports program type and map type.

Also add const fn bpf_insn::new(...) so that common bpf instructions are not re-computed every time from copy_instructions().

Assertions for LircMode2 and Lsm are disabled because they require certain kernel configs to be enabled, which are not by default in VM integration tests. Same with InodeStorage map assertion.

I tested the new integration tests against a ton of ubuntu mainline kernels. Basically on every version where the program/map type was introduced I was able to verify that they were passing as expected, except for ones below v4.4 since it gave errors on /sys/fs/bpf ENOENT: No such file or directory.
