From: Geliang Tang <tanggeliang(a)kylinos.cn> This patchset addresses Alexei's comment for commit "Handle SIGINT when creating netns" [1]. Export local helpers create_netns() and cleanup_netns() defined in mptcp.c into network_helpers.c as generic ones. For this another helper unshare_netns() is added to replace the existing local helpers create_netns().

[PATCH 6.6.y] kselftest: Add a ksft_perror() helper

by Edward Liaw

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 907f33028871fa7c9a3db1efd467b78ef82cce20 ] The standard library perror() function provides a convenient way to print an error message based on the current errno but this doesn't play nicely with KTAP output. Provide a helper which does an equivalent thing in a KTAP compatible format. nolibc doesn't have a strerror() and adding the table of strings required doesn't seem like a good fit for what it's trying to do so when we're using that only print the errno.

[PATCH v1 0/4] add tests to verify IFS (In Field Scan) driver functionality

by Pengfei Xu

To verify IFS (In Field Scan [1]) driver functionality, add the following 6 test cases: 1. Verify that IFS sysfs entries are created after loading the IFS module 2. Check if loading an invalid IFS test image fails and loading a valid one succeeds 3. Perform IFS scan test on each CPU using all the available image files 4. Perform IFS scan with first test image file on a random CPU for 3 rounds 5. Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU 6. Perform IFS ARRAY BIST test on a random CPU for 3 rounds These are not exhaustive, but some minimal test runs to check various parts of the driver. Some negative tests are also included.

[PATCH v3] kunit: Cover 'assert.c' with tests

by Ivan Orlov

There are multiple assertion formatting functions in the `assert.c` file, which are not covered with tests yet. Implement the KUnit test for these functions. The test consists of 11 test cases for the following functions: 1) 'is_literal' 2) 'is_str_literal' 3) 'kunit_assert_prologue', test case for multiple assert types 4) 'kunit_assert_print_msg' 5) 'kunit_unary_assert_format' 6) 'kunit_ptr_not_err_assert_format' 7) 'kunit_binary_assert_format' 8) 'kunit_binary_ptr_assert_format' 9) 'kunit_binary_str_assert_format' 10) 'kunit_assert_hexdump' 11) 'kunit_mem_assert_format' The test aims at maximizing the branch coverage for the assertion formatting functions. As you can see, it covers some of the static helper functions as well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT' and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the corresponding definitions to `assert.h`. Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to how it is done for the string stream test. Signed-off-by: Ivan Orlov <ivan.orlov0322(a)gmail.com> --- V1 -> V2: - Check the output from the string stream for containing the key parts instead of comparing the results with expected strings char by char, as it was suggested by Rae Moar <rmoar(a)google.com>. Define two macros to make it possible (ASSERT_TEST_EXPECT_CONTAIN and ASSERT_TEST_EXPECT_NCONTAIN). - Mark the static functions in `assert.c` as VISIBLE_IF_KUNIT and export them conditionally if kunit is enabled instead of including the `assert_test.c` file in the end of `assert.c`. This way we will decouple the test from the implementation (SUT). - Update the kunit_assert_hexdump test: now it checks for presense of the brackets '<>' around the non-matching bytes, instead of comparing the kunit_assert_hexdump output char by char. V2 -> V3: - Make test case array and test suite definitions static - Change the condition in `assert.h`: we should declare VISIBLE_IF_KUNIT functions in the header file when CONFIG_KUNIT is enabled, not CONFIG_KUNIT_TEST. Otherwise, if CONFIG_KUNIT_TEST is disabled, VISIBLE_IF_KUNIT functions in the `assert.c` are not static, and prototypes for them can't be found. - Add MODULE_LICENSE and MODULE_DESCRIPTION macros include/kunit/assert.h | 11 ++ lib/kunit/Makefile | 1 + lib/kunit/assert.c | 24 ++- lib/kunit/assert_test.c | 391 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 419 insertions(+), 8 deletions(-) create mode 100644 lib/kunit/assert_test.c diff --git a/include/kunit/assert.h b/include/kunit/assert.h index 24c2b9fa61e8..7e7490a74b13 100644 --- a/include/kunit/assert.h +++ b/include/kunit/assert.h @@ -218,4 +218,15 @@ void kunit_mem_assert_format(const struct kunit_assert *assert, const struct va_format *message, struct string_stream *stream); +#if IS_ENABLED(CONFIG_KUNIT) +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream); +bool is_literal(const char *text, long long value); +bool is_str_literal(const char *text, const char *value); +void kunit_assert_hexdump(struct string_stream *stream, + const void *buf, + const void *compared_buf, + const size_t len); +#endif + #endif /* _KUNIT_ASSERT_H */ diff --git a/lib/kunit/Makefile b/lib/kunit/Makefile index 309659a32a78..be7c9903936f 100644 --- a/lib/kunit/Makefile +++ b/lib/kunit/Makefile @@ -18,6 +18,7 @@ endif obj-y += hooks.o obj-$(CONFIG_KUNIT_TEST) += kunit-test.o +obj-$(CONFIG_KUNIT_TEST) += assert_test.o # string-stream-test compiles built-in only. ifeq ($(CONFIG_KUNIT_TEST),y) diff --git a/lib/kunit/assert.c b/lib/kunit/assert.c index dd1d633d0fe2..382eb409d34b 100644 --- a/lib/kunit/assert.c +++ b/lib/kunit/assert.c @@ -7,6 +7,7 @@ */ #include <kunit/assert.h> #include <kunit/test.h> +#include <kunit/visibility.h> #include "string-stream.h" @@ -30,12 +31,14 @@ void kunit_assert_prologue(const struct kunit_loc *loc, } EXPORT_SYMBOL_GPL(kunit_assert_prologue); -static void kunit_assert_print_msg(const struct va_format *message, - struct string_stream *stream) +VISIBLE_IF_KUNIT +void kunit_assert_print_msg(const struct va_format *message, + struct string_stream *stream) { if (message->fmt) string_stream_add(stream, "\n%pV", message); } +EXPORT_SYMBOL_IF_KUNIT(kunit_assert_print_msg); void kunit_fail_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -89,7 +92,7 @@ void kunit_ptr_not_err_assert_format(const struct kunit_assert *assert, EXPORT_SYMBOL_GPL(kunit_ptr_not_err_assert_format); /* Checks if `text` is a literal representing `value`, e.g. "5" and 5 */ -static bool is_literal(const char *text, long long value) +VISIBLE_IF_KUNIT bool is_literal(const char *text, long long value) { char *buffer; int len; @@ -110,6 +113,7 @@ static bool is_literal(const char *text, long long value) return ret; } +EXPORT_SYMBOL_IF_KUNIT(is_literal); void kunit_binary_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -166,7 +170,7 @@ EXPORT_SYMBOL_GPL(kunit_binary_ptr_assert_format); /* Checks if KUNIT_EXPECT_STREQ() args were string literals. * Note: `text` will have ""s where as `value` will not. */ -static bool is_str_literal(const char *text, const char *value) +VISIBLE_IF_KUNIT bool is_str_literal(const char *text, const char *value) { int len; @@ -178,6 +182,7 @@ static bool is_str_literal(const char *text, const char *value) return strncmp(text + 1, value, len - 2) == 0; } +EXPORT_SYMBOL_IF_KUNIT(is_str_literal); void kunit_binary_str_assert_format(const struct kunit_assert *assert, const struct va_format *message, @@ -208,10 +213,11 @@ EXPORT_SYMBOL_GPL(kunit_binary_str_assert_format); /* Adds a hexdump of a buffer to a string_stream comparing it with * a second buffer.

Hi Linus, Please pull the kselftest update for Linux 6.10-rc1. This kselftest update for Linux 6.10-rc1 consists of: - changes to make framework and tests reporting KTAP compliant - changes to make ktap_helpers and power_supply test POSIX compliant - adds ksft_exit_fail_perror() to include errono in string form - fixes to avoid clang reporting false positive static analysis errors about functions that exit and never return. ksft_exit* functions are marked __noreturn to address this problem - adds mechanism for reporting a KSFT_ result code - fixes to build warnings related missing headers and unused variables - fixes to clang build failures - cleanups to resctrl test - adds host arch for LLVM builds Please note that Stepen found the following conflict in tools/testing/selftests/mm/soft-dirty.c in next and fixed it up. between commit: 258ff696db6b ("selftests/mm: soft-dirty should fail if a testcase fails") from the mm-unstable branch of the mm tree and commit: e6162a96c81d ("selftests/mm: ksft_exit functions do not return") from the kselftest tree.
