debug: Add fortify wprintf tests

2023-12-29T13:57:27Z

Similar to other printf-like ones. It requires to be in a different process so we can change the orientation of stdout. Checked on aarch64, armhf, x86_64, and i686.

debug: Add fortify syslog tests

2023-12-29T13:57:03Z

It requires to be in a container tests to avoid logging bogus information on the system. The syslog also requires to be checked in a different process because the internal printf call will abort with the internal syslog lock taken (which makes subsequent syslog calls deadlock). Checked on aarch64, armhf, x86_64, and i686. Reviewed-by: Siddhesh Poyarekar

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.

Add the wcslcpy, wcslcat functions

2023-06-14T16:10:24Z

These functions are about to be added to POSIX, under Austin Group issue 986. Reviewed-by: Siddhesh Poyarekar

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

debug: Reformat Makefile.

2023-05-16T11:17:19Z

Fix list terminator whitspace. Sort using scripts/sort-makefile-lines.py. No code generation changes observed in binary artifacts. No regressions on x86_64 and i686.

stdio-common: Handle -1 buffer size in __sprintf_chk & co (bug 30039)

2023-01-25T07:01:00Z

This shows up as an assertion failure when sprintf is called with a specifier like "%.8g" and libquadmath is linked in: Fatal glibc error: printf_buffer_as_file.c:31 (__printf_buffer_as_file_commit): assertion failed: file->stream._IO_write_ptr <= file->next->write_end Fix this by detecting pointer wraparound in __vsprintf_internal and saturate the addition to the end of the address space instead.
