Dmitrii Dolgov cbdaf71f7e bpftool: Add bpf_cookie to link output Commit `82e6b1eee6` ("bpf: Allow to specify user-provided bpf_cookie for BPF perf links") introduced the concept of user specified bpf_cookie, which could be accessed by BPF programs using bpf_get_attach_cookie(). For troubleshooting purposes it is convenient to expose bpf_cookie via bpftool as well, so there is no need to meddle with the target BPF program itself. Implemented using the pid iterator BPF program to actually fetch bpf_cookies, which allows constraining code changes only to bpftool. $ bpftool link 1: type 7 prog 5 bpf_cookie 123 pids bootstrap(81) Signed-off-by: Dmitrii Dolgov <9erthalion6@gmail.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Yonghong Song <yhs@fb.com> Acked-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/bpf/20220309163112.24141-1-9erthalion6@gmail.com		2022-03-15 15:07:27 -07:00

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
