^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) drgn scripts is a convenient and easy to use mechanism to retrieve arbitrary
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) kernel data structures. drgn is not relying on kernel UAPI to read the data.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) Instead it's reading directly from ``/proc/kcore`` or vmcore and pretty prints
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) the data based on DWARF debug information from vmlinux.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) ===========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) `bpf_inspect.py`_ is a tool intended to inspect BPF programs and maps. It can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) iterate over all programs and maps in the system and print basic information
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) about these objects, including id, type and name.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) The main use-case `bpf_inspect.py`_ covers is to show BPF programs of types
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) ``BPF_PROG_TYPE_EXT`` and ``BPF_PROG_TYPE_TRACING`` attached to other BPF
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) programs via ``freplace``/``fentry``/``fexit`` mechanisms, since there is no
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) user-space API to get this information.
