Andrii Nakryiko says: ==================== Teach veristat how to deal with freplace BPF programs. As they can't be directly loaded by veristat without custom user-space part that sets correct target program FD, veristat always fails freplace programs. This patch set teaches veristat to guess target program type that will be inherited by freplace program itself, and subtitute it for BPF_PROG_TYPE_EXT (freplace) one for the purposes of BPF verification. Patch #1 fixes bug in libbpf preventing overriding freplace with specific program type. Patch #2 adds convenient -d flag to request veristat to emit libbpf debug logs. It help debugging why a specific BPF program fails to load, if the problem is not due to BPF verification itself. v3->v4: - fix optional kern_name check when guessing prog type (Alexei); v2->v3: - fix bpf_obj_id selftest that uses legacy bpf_prog_test_load() helper, which always sets program type programmatically; teach the helper to do it only if actually necessary (Stanislav); v1->v2: - fix compilation error reported by old GCC (my GCC v11 doesn't produce even a warning) and Clang (see CI failure at [0]): GCC version: veristat.c: In function ‘fixup_obj’: veristat.c:908:1: error: label at end of compound statement 908 | skip_freplace_fixup: | ^~~~~~~~~~~~~~~~~~~ Clang version: veristat.c:909:1: error: label at end of compound statement is a C2x extension [-Werror,-Wc2x-extensions] } ^ 1 error generated.

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.
