Gregory Bell says: ==================== Fix verifier test failures in verbose mode This patch series fixes two issues that cause false failures in the BPF verifier test suite when run with verbose output (`-v`). The following tests fail only when running the test_verifier in verbose. This leads to inconsistent results across verbose and non-verbose runs. Patch 1 addresses an issue where the verbose flag (`-v`) unintentionally overrides the `opts.log_level`, leading to incorrect contents when checking bpf_vlog in tests with `expected_ret == VERBOSE_ACCEPT`. This occurs when running verbose with `-v` but not `-vv` Patch 2 increases the size of the `bpf_vlog[]` buffer to prevent truncation of large verifier logs, which was causing failures in several scale and 64-bit immediate tests. Before patches: ./test_verifier | grep FAIL Summary: 790 PASSED, 0 SKIPPED, 0 FAILED ./test_verifier -v | grep FAIL Summary: 782 PASSED, 0 SKIPPED, 8 FAILED ./test_verifier -vv | grep FAIL Summary: 787 PASSED, 0 SKIPPED, 3 FAILED After patches: ./test_verifier -v | grep FAIL Summary: 790 PASSED, 0 SKIPPED, 0 FAILED ./test_verifier -vv | grep FAIL Summary: 790 PASSED, 0 SKIPPED, 0 FAILED These fixes improve test reliability and ensure consistent behavior across verbose and non-verbose runs. ==================== Tested-by: Eduard Zingerman <eddyz87@gmail.com> Link: https://patch.msgid.link/cover.1747058195.git.grbell@redhat.com Signed-off-by: Alexei Starovoitov <ast@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 reStructuredText 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.
