seq_buf: Introduce KUnit tests Add KUnit tests for the seq_buf API to ensure its correctness and prevent future regressions, covering the following functions: - seq_buf_init() - DECLARE_SEQ_BUF() - seq_buf_clear() - seq_buf_puts() - seq_buf_putc() - seq_buf_printf() - seq_buf_get_buf() - seq_buf_commit() $ tools/testing/kunit/kunit.py run seq_buf =================== seq_buf (9 subtests) =================== [PASSED] seq_buf_init_test [PASSED] seq_buf_declare_test [PASSED] seq_buf_clear_test [PASSED] seq_buf_puts_test [PASSED] seq_buf_puts_overflow_test [PASSED] seq_buf_putc_test [PASSED] seq_buf_printf_test [PASSED] seq_buf_printf_overflow_test [PASSED] seq_buf_get_buf_commit_test ===================== [PASSED] seq_buf ===================== Link: https://lore.kernel.org/r/20250717085156.work.363-kees@kernel.org Reviewed-by: David Gow <davidgow@google.com> Signed-off-by: Kees Cook <kees@kernel.org>

seq_buf: Export seq_buf_putmem_hex() and add KUnit tests The seq_buf KUnit suite does not exercise seq_buf_putmem_hex(). Add one test for the len > 8 chunking path and one overflow test where a later chunk no longer fits in the buffer. Export seq_buf_putmem_hex() as well so SEQ_BUF_KUNIT_TEST=m links cleanly. Without the export, modpost reports seq_buf_putmem_hex as undefined when seq_buf_kunit is built as a module.
