We sometimes need to compare whole structures in an assert. It is possible to use the existing macros on each field, but when the whole structure has to be checked, it is more convenient to simply compare the whole structure memory Add a dedicated assert macro, ASSERT_MEMEQ, to allow bare memory comparision The output generated by this new macro looks like the following: [...] run_tests_skb_less:FAIL:returned flow keys unexpected memory mismatch actual: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 expected: 0E 00 3E 00 DD 86 01 01 00 06 86 DD 50 00 90 1F 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 [...] Acked-by: Stanislav Fomichev <sdf@fomichev.me> Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com> Link: https://lore.kernel.org/r/20241120-flow_dissector-v3-1-45b46494f937@bootlin.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.
