This patch adds support to verifier tests to check for a succession of verifier log messages on program load failure. This makes the errstr field work uniformly across REJECT and VERBOSE_ACCEPT checks. This patch also increases the maximum size of a message in the series of messages to test from 80 chars to 200 chars. This is in order to keep existing tests working, which sometimes test for messages larger than 80 chars (which was accepted in the REJECT case, when testing for a single message, but not in the VERBOSE_ACCEPT case, when testing for possibly multiple messages). And example of such a long, checked message is in bounds.c: "R1 has unknown scalar with mixed signed bounds, pointer arithmetic with it prohibited for !root" Signed-off-by: Andrei Matei <andreimatei1@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Song Liu <songliubraving@fb.com> Link: https://lore.kernel.org/bpf/20210130220150.59305-1-andreimatei1@gmail.com
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.
