io: replace local_isatty() with a proper function __isatty_nostatus()

2025-06-17T12:11:38+00:00

Replace local_isatty() inlined in libio with a proper function
__isatty_nostatus(). This allows simpler system-specific
implementations that don't need to touch errno at all.

Note: I left the prototype in include/unistd.h (the internal header
file.) It didn't much make sense to me to put it in a different header
(not-cancel.h), but perhaps someone can elucidate the need.

Add such an implementation for Linux, with a generic fallback.

Do not use -Wp to disable fortify (BZ 31928)

2024-10-01T11:44:40+00:00

The -Wp does not work properly if the compiler is configured to enable
fortify by default, since it bypasses the compiler driver (which defines
the fortify flags in this case).

This patch is similar to the one used on Ubuntu [1].

I checked with a build for x86_64-linux-gnu, i686-linux-gnu,
aarch64-linux-gnu, s390x-linux-gnu, and riscv64-linux-gnu with
gcc-13 that enables the fortify by default.

io: Add error tests for fchmod

2024-08-30T19:12:01+00:00

On Linux most descriptors that do not correspond to file system
entities (such as anonymous pipes and sockets) have file permissions
that can be changed.  While it is possible to create a custom file
system that returns (say) EINVAL for an fchmod attempt, testing this
does not appear to be useful.

cdefs: Drop access attribute for _FORTIFY_SOURCE=3 (BZ #31383)

2024-02-28T13:35:10+00:00

When passed a pointer to a zero-sized struct, the access attribute
without the third argument misleads -Wstringop-overflow diagnostics to
think that a function is writing 1 byte into the zero-sized structs.
The attribute doesn't add that much value in this context, so drop it
completely for _FORTIFY_SOURCE=3.
