Hello, strace community!
Project: Advanced syscall filtering syntax.
Accomplishments: this week I've added implementation of path filtering
and began writing tests for filtering.
Next week I am going to refactor v3 implementation of advanced filtering
according to its reviews. Also I am going to
It was too bad last week, it seem did nothing.
I fixed some code, merged some patch.
This week, I will fix packet_diag_msg, smc_diag_msg and inet_diag_req
attribute decode, and extend the macro in tests/test_nlattr.h,
make it suit for more case, because now I can not use them in
tests/nlattr_inet_

My bad, didn't notice that filter_actions is invalid in that case, thanks!
