[PATCH v3 1/3] selftests: net: .gitignore the scratch directory of bpf

by Andrei Gherzan

The net/bpf Makefile uses a similar build infrastructure to BPF[1] while building libbpf as a dependency of nat6to4. This change adds a .gitignore entry for SCRATCH_DIR where libbpf and its headers end up built/installed.

[PATCH v2 1/2] selftests: net: Fix missing nat6to4.o when running udpgro_frglist.sh

by Andrei Gherzan

The udpgro_frglist.sh uses nat6to4.o which is tested for existence in bpf/nat6to4.o (relative to the script). This is where the object is compiled. Even so, the script attempts to use it as part of tc with a different path (../bpf/nat6to4.o). As a consequence, this fails the script: Error opening object ../bpf/nat6to4.o: No such file or directory Cannot initialize ELF context! Unable to load program This change refactors these references to use a variable for consistency and also reformats two long lines.

[RFC PATCH v2] kunit: Add "hooks" to call into KUnit when it's built as a module

by David Gow

KUnit has several macros and functions intended for use from non-test code. These hooks, currently the kunit_get_current_test() and kunit_fail_current_test() macros, didn't work when CONFIG_KUNIT=m. In order to support this case, the required functions and static data need to be available unconditionally, even when KUnit itself is not built-in. The new 'hooks.c' file is therefore always included, and has both the static key required for kunit_get_current_test(), and a function pointer to the real implementation of __kunit_fail_current_test(), which is populated when the KUnit module is loaded. A new header, kunit/hooks-table.h, contains a table of all hooks, and is repeatedly included with different definitions of the KUNIT_HOOK() in order to automatically generate the needed function pointer tables. When KUnit is disabled, or the module is not loaded, these function pointers are all NULL. This shouldn't be a problem, as they're all used behind wrappers which check kunit_running and/or that the pointer is non-NULL. This can then be extended for future features which require similar "hook" behaviour, such as static stubs: https://lore.kernel.org/all/20221208061841.2186447-1-davidgow@google.com/ Signed-off-by: David Gow <davidgow(a)google.com> --- This is basically a prerequisite for the stub features working when KUnit is built as a module, and should nicely make a few other tests work then, too. v2 adds a slightly-excessive macro-based system for defining hooks. This made adding the static stub hooks absolutely trivial, and the complexity is totally hidden from the user (being an internal KUnit implementation detail), so I'm more comfortable with this than some other macro magic. It does however result in a huge number of checkpatch.pl errors, as we're using macros in unconventional ways, and checkpatch just can't work out the syntax. These are mostly "Macros with complex values should be enclosed in parentheses", "Macros with multiple statements should be enclosed in a do - while loop", and similar, which don't apply due to the macros not being expressions: they are mostly declarations or assignment statements. There are a few others where checkpatch thinks that the return value is the function name and similar, so complains about the style. Open questions: - Is this macro-based system worth it, or was v1 better? - Should we rename test-bug.h to hooks.h or similar. (I think so, but would rather do it in a separate patch, to make it easier to review. There are a few includes of it scattered about.) - Is making these NULL when KUnit isn't around sensible, or should we auto-generate a "default" implementation. This is a pretty easy extension to the macros here. (I think NULL is good for now, as we have wrappers for these anyway. If we want to change our minds later as we add more hooks, it's easy.) - Any other thoughts? Cheers, -- David Changes since RFC v1: https://lore.kernel.org/all/20230117142737.246446-1-davidgow@google.com/ - Major refit to auto-generate the hook code using macros. - (Note that previous Reviewed-by tags have not been added, as this is a big enough change it probably needs a re-reviews.

[PATCH v3] lib/hashtable_test.c: add test for the hashtable structure

by Rae Moar

Add a KUnit test for the kernel hashtable implementation in include/linux/hashtable.h. Note that this version does not yet test each of the rcu alternative versions of functions. Signed-off-by: Rae Moar <rmoar(a)google.com> Reviewed-by: David Gow <davidgow(a)google.com> --- Changes since v2: - Remove extraneous hash_init() calls when using DEFINE_HASHTABLE. - Change up the size of the hashtables in different tests. - Change formatting to group lines regarding the same hashtable_test_entry. - Use KUNIT_ASSERT_LEQ() and KUNIT_ASSERT_GEQ() instead of a few if statements. Changes since v1: - Change Kconfig.debug message to be more succinct. - Directly increment current element's visited field rather than looking up corresponding element. - Use KUNIT_ASSERT_... statements to check the keys are within range rather than using if statements. - Change hash_for_each_possible test to check buckets using a hash_for_each method instead of calculating the bucket number using hash_min. Note: The check patch script is outputting open brace errors on lines 152, 185, 239 of lib/hashtable_test.c. However, I think these errors are a mistake as the format of the braces on those lines is consistent with the Linux Kernel style guide. As David Gow commented on the last version, "This is a known issue with checkpatch and function names with "for_each" in them.
