Question on PBR daemon
by Atul Chowdhry 26 Mar '21

26 Mar '21

Hi Guys, I was looking at PBR daemon code and looks like in current code, the whole pbr-policy (struct pbr_map) is considered to invalid if any one of the contained rules (struct pbr_map_sequence) inside the policy becomes invalid. I cannot figure the reason for this design choice. To me it looks like policy rules are pretty much independent and policy is just a container for these rules. What am I missing? I will really appreciate it if anyone can reply to my query. Thanks a lot in advance. Rgds Atul
