| D | prog_cgroup_sysctl.rst | 8 provides cgroup-bpf hook for sysctl.
11 process inside that cgroup tries to read from or write to sysctl knob in proc.
30 * ``write`` indicates whether sysctl value is being read (``0``) or written
33 * ``file_pos`` indicates file position sysctl is being accessed at, read
35 position in sysctl proc file ``read(2)`` will be reading from or ``write(2)``
37 whole sysctl value by ``bpf_sysctl_set_new_value()`` on ``write(2)`` even
39 value to the field can be used to access part of sysctl value starting from
40 specified ``file_pos``. Not all sysctl support access with ``file_pos !=
41 0``, e.g. writes to numeric sysctl entries must always be at file position
42 ``0``. See also ``kernel.sysctl_writes_strict`` sysctl.
