Could @alindima @roypat @rbradford take a look when convenient 🙂

LGTM, but the syscall table validation is failing in the CI for aarch64. is there something wrong with the script? Looks like it's comparing syscall tables of different architectures

Yes, tools/generate_syscall_tables.sh does work with recent kernel anymore, I'm working converting this script as a part of header-gen (a tiny program going to be integrated in rust-vmm-ci) since in other repos we are doing something similar.

Can we merge this now @alindima 🙂 for works to be finished in rust-vmm-ci could take a while

[alindima]

Hmm, but if you're saying that the script does not for recent kernel versions, how did you generate the tables in the first place? which script did you use?

Can you detail a bit what is the problem with the new kernel? Is there a relevant PR in rust-vmm-ci?

Noted, let me re-organize my code and raise a PR to rust-vmm-ci. Then I'll get back to you

@alindima A prototype is available here: rust-vmm/rust-vmm-ci#177, you can verify the generated code through command:

rustvmm_gen/rustvmm_gen.py --arch arm64 --version 6.12.8 generate_syscall

Since the validation could take a while to resolve, can I propose to release 0.5.0 of seccompiler as it is now 🤔

It's blocking our downstream from launching RISC-V support 🥹

[alindima]

LGTM, just some nits. Thanks for updating the scripts

[RuoqingHe]

@alindima Thanks for going through the lines, can we merge it and release with 0.5.0 🙂, I will form a release PR later

Sounds good to me, merged it
