Enhanced test coverage for strncmp, wcsncmp

2024-08-01T07:08:32Z

Add string/test-strncmp-nonarray and wcsmbs/test-wcsncmp-nonarray. This is the test that uncovered bug 31934. Test run time is more than one minute on a fairly current system, so turn these into xtests that do not run automatically. Reviewed-by: Noah Goldstein

string: Disable stack protector for memset in early static initialization

2024-01-23T13:22:59Z

For ports that use the default memset, the compiler might generate early calls before the stack protector is initialized (for instance, riscv with -fstack-protector-all on _dl_aux_init). Checked on riscv64-linux-gnu-rv64imafdc-lp64d. Reviewed-by: Florian Weimer

string: Add internal memswap implementation

2023-10-31T17:17:33Z

The prototype is: void __memswap (void *restrict p1, void *restrict p2, size_t n) The function swaps the content of two memory blocks P1 and P2 of len N. Memory overlap is NOT handled. It will be used on qsort optimization. Checked on x86_64-linux-gnu and aarch64-linux-gnu. Reviewed-by: Noah Goldstein

Add strlcat/wcslcat testcase.

Exclude routines from fortification

2023-07-05T14:59:48Z

Since the _FORTIFY_SOURCE feature uses some routines of Glibc, they need to be excluded from the fortification. On top of that: - some tests explicitly verify that some level of fortification works appropriately, we therefore shouldn't modify the level set for them. - some objects need to be build with optimization disabled, which prevents _FORTIFY_SOURCE to be used for them. Assembler files that implement architecture specific versions of the fortified routines were not excluded from _FORTIFY_SOURCE as there is no C header included that would impact their behavior.

string: strerror must not return NULL (bug 30555)

2023-06-15T17:54:09Z

For strerror, this fixes commit 28aff047818eb1726394296d27b ("string: Implement strerror in terms of strerror_l"). This commit avoids returning NULL for strerror_l as well, although POSIX allows this behavior for strerror_l. Reviewed-by: Arjun Shankar

Implement strlcpy and strlcat [BZ #178]

2023-06-14T16:10:08Z

These functions are about to be added to POSIX, under Austin Group issue 986. The fortified strlcat implementation does not raise SIGABRT if the destination buffer does not contain a null terminator, it just inherits the non-failing regular strlcat behavior. Reviewed-by: Siddhesh Poyarekar
