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/poll: drop __NR_poll fallback

2026-01-04T09:28:58+00:00

This fallback is never used, remove it.

tools/nolibc/poll: use kernel types for system call invocations

2026-01-04T09:28:57+00:00

The system calls expect 'struct __kernel_old_timespec'. While currently 'struct __kernel_old_timespec' and 'struct timespec' are compatible, this is confusing. Especially as future patches will change the definition of 'struct timespec'. Use the correct kernel type instead.

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: use poll-related definitions from UAPI headers

2025-05-21T13:32:00+00:00

The UAPI headers already provide definitions for these symbols. Using them makes the code shorter, more robust and compatible with applications using linux/poll.h directly.
