[PATCH v8] fat: Add KUnit tests for checksums and timestamps

by David Gow

Add some basic sanity-check tests for the fat_checksum() function and the fat_time_unix2fat() and fat_time_fat2unix() functions. These unit tests verify these functions return correct output for a number of test inputs. These tests were inspored by -- and serve a similar purpose to -- the timestamp parsing KUnit tests in ext4[1]. Note that, unlike fat_time_unix2fat, fat_time_fat2unix wasn't previously exported, so this patch exports it as well. This is required for the case where we're building the fat and fat_test as modules. [1]: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/fs/… Signed-off-by: David Gow <davidgow(a)google.com> Acked-by: OGAWA Hirofumi <hirofumi(a)mail.parknet.co.jp> --- It's been a while, but this hopefully is a final version of the FAT KUnit patchset. It has a number of changes to keep it up-to-date with current KUnit standards, notably the use of parameterised tests and the addition of a '.kunitconfig' file to allow for easy testing. It also fixes an endianness tagging issue picked up by the kernel test robot under sparse on pa-risc. Cheers, -- David Changes since v7: https://lore.kernel.org/linux-kselftest/20201028064631.3774908-1-davidgow@g… - Make the two timestamp tests parameterised: this means that the KUnit runtime and tooling are aware of the different testcases (and print a nice list of them to the TAP log when the test is run). - Fix some issues sparse picked up with __le32 tagged integers. - Add an fs/fat/.kunitconfig file which contains all the Kconfig entries needed to run the test. The test can now be run with: ./tools/testing/kunit/kunit.py run --kunitconfig fs/fat/.kunitconfig Changes since v6: https://lore.kernel.org/linux-kselftest/20201024060558.2556249-1-davidgow@g… - Make CONFIG_FAT_DEFAULT_CODEPAGE depend on FAT_FS, rather than either VFAT_FS or MSDOS_FS. - This means that FAT_KUNIT_TEST can now also just depend of FAT_FS - Fix a few warnings that KUnit tool was eating: - KUnit's type checking needs a specific cast for the fat_checksum() expected results. - The time test cases shouldn't be 'const' - The fake superblock is now static, as otherwise it increased the stack size too much. Changes since v4/5: https://lore.kernel.org/linux-kselftest/20201024052047.2526780-1-davidgow@g… - Fix a typo introduced in the Kconfig. It builds now. Changes since v3: https://lore.kernel.org/linux-kselftest/20201021061713.1545931-1-davidgow@g… - Update the Kconfig entry to use "depends on" rather than "select", as discussed in [2]. - Depend on "MSDOS_FS || VFAT_FS", rather than "FAT_FS", as we need the CONFIG_FAT_DEFAULT_CODEPAGE symbol to be defined. Changes since v2: https://lore.kernel.org/linux-kselftest/20201020055856.1270482-1-davidgow@g… - Comment that the export for fat_time_fat2unix() function is for KUnit tests. Changes since v1: https://lore.kernel.org/linux-kselftest/20201017064107.375174-1-davidgow@go… - Now export fat_time_fat2unix() so that the test can access it when built as a module.

[PATCH] kbuild: replace LANG=C with LC_ALL=C

by Masahiro Yamada

LANG gives a weak default to each LC_* in case it is not explicitly defined. LC_ALL, if set, overrides all other LC_* variables. LANG < LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, ... < LC_ALL This is why documentation such as [1] suggests to set LC_ALL in build scripts to get the deterministic result. LANG=C is not strong enough to override LC_* that may be set by end users.

[PATCH AUTOSEL 5.10 78/85] selftests: mlxsw: Fix mausezahn invocation in ERSPAN scale test

by Sasha Levin

From: Petr Machata <petrm(a)nvidia.com> [ Upstream commit 1233898ab758cbcf5f6fea10b8dd16a0b2c24fab ] The mirror_gre_scale test creates as many ERSPAN sessions as the underlying chip supports, and tests that they all work. In order to determine that it issues a stream of ICMP packets and checks if they are mirrored as expected. However, the mausezahn invocation missed the -6 flag to identify the use of IPv6 protocol, and was sending ICMP messages over IPv6, as opposed to ICMP6. It also didn't pass an explicit source IP address, which apparently worked at some point in the past, but does not anymore. To fix these issues, extend the function mirror_test() in mirror_lib by detecting the IPv6 protocol addresses, and using a different ICMP scheme. Fix __mirror_gre_test() in the selftest itself to pass a source IP address. Signed-off-by: Petr Machata <petrm(a)nvidia.com> Signed-off-by: David S.
