From c501bf55c88b834adefda870c7c092ec9052a437 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 2 Mar 2023 09:42:59 -1000 Subject: bpf: Make bpf_get_current_[ancestor_]cgroup_id() available for all program types These helpers are safe to call from any context and there's no reason to restrict access to them. Remove them from bpf_trace and filter lists and add to bpf_base_func_proto() under perfmon_capable(). v2: After consulting with Andrii, relocated in bpf_base_func_proto() so that they require bpf_capable() but not perfomon_capable() as it doesn't read from or affect others on the system.
