Linux kernel source tree

Quentin Monnet says: ==================== At runtime, bpftool may run its own BPF programs to get the pids of processes referencing BPF programs, or to profile programs. The skeletons for these programs rely on a vmlinux.h header and may fail to compile when building bpftool on hosts running older kernels, where some structs or enums are not defined. In this set, we address this issue by using local definitions for struct perf_event, struct bpf_perf_link, BPF_LINK_TYPE_PERF_EVENT (pids.bpf.c) and struct bpf_perf_event_value (profiler.bpf.c). This set contains patches 1 to 3 from Alexander Lobakin's series, "bpf: random unpopular userspace fixes (32 bit et al)" (v2) [0], from April 2022. An additional patch defines a local version of BPF_LINK_TYPE_PERF_EVENT in bpftool's pids.bpf.c. [0] https://lore.kernel.org/bpf/20220421003152.339542-1-alobakin@pm.me/ v2: Fixed description (CO-RE for container_of()) in patch 2. Cc: Alexander Lobakin <aleksander.lobakin@intel.com> Cc: Michal Suchánek <msuchanek@suse.de> Alexander Lobakin (3): bpftool: use a local copy of perf_event to fix accessing ::bpf_cookie bpftool: define a local bpf_perf_link to fix accessing its fields bpftool: use a local bpf_perf_event_value to fix accessing its fields ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org> |

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.
