A Dprog_cgroup_sysctl.rst8 provides cgroup-bpf hook for sysctl.
11 process inside that cgroup tries to read from or write to sysctl knob in proc.
33 * ``file_pos`` indicates file position sysctl is being accessed at, read
42 ``0``. See also ``kernel.sysctl_writes_strict`` sysctl.
52 * ``0`` means "reject access to sysctl";
61 Since sysctl knob is represented by a name and a value, sysctl specific BPF
64 * ``bpf_sysctl_get_name()`` to get sysctl name as it is visible in
69 ``read(2)`` from and ``write(2)`` to sysctl;
76 written to sysctl before actual write happens. Sysctl value will be
100 the result to make decision whether to allow or deny access to sysctl.
