selftests/nolibc: add static assertions around time types handling

2026-01-06T11:08:08+00:00

The nolibc system call wrappers expect the libc types to be compatible to the kernel types. Make sure these expectations hold at compile-time.

tools/nolibc: remove time conversions

2026-01-06T11:08:06+00:00

Now that 'struct timespec' and 'struct __kernel_timespec' are compatible, the conversions are not necessary anymore. The same holds true for 'struct itimerspec' and 'struct __kernel_itimerspec'. Remove the conversions. Signed-off-by: Thomas Weißschuh Acked-by: Willy Tarreau Reviewed-by: Arnd Bergmann Link: https://patch.msgid.link/20251220-nolibc-uapi-types-v3-11-c662992f75d7@weissschuh.net

tools/nolibc: prefer explicit 64-bit time-related system calls

2026-01-04T09:29:00+00:00

Make sure to always use the 64-bit safe system calls in preparation for 64-bit time_t on 32-bit architectures. Also prevent issues on kernels which disable CONFIG_COMPAT_32BIT_TIME and therefore don't provide the 32-bit system calls anymore.

tools/nolibc: remove more __nolibc_enosys() fallbacks

2025-11-20T18:47:11+00:00

Commit e6366101ce1f ("tools/nolibc: remove __nolibc_enosys() fallback from time64-related functions") removed many of these fallbacks but forgot a few. Finish the job. Signed-off-by: Thomas Weißschuh Acked-by: Willy Tarreau

tools/nolibc: remove __nolibc_enosys() fallback from time64-related functions

2025-09-01T18:47:51+00:00

These fallbacks where added when no explicit fallbacks for time64 was implemented. Now that these fallbacks are in place, the additional fallback to __nolibc_enosys() is superfluous.

tools/nolibc: fix error return value of clock_nanosleep()

2025-08-17T09:42:09+00:00

clock_nanosleep() returns a positive error value. Unlike other libc functions it *does not* return -1 nor set errno. Fix the return value and also adapt nanosleep().
