crypto/sleep.c: avoid returning early due to signal

2025-08-09T19:52:24Z

On POSIX systems, sleep/usleep/nanosleep may return early due to arrival of a signal, and OSSL_sleep does not report that, so it is assumed that it cannot return early. Fix that by introducing a loop that checks the remaining time and sleep some more if the time has not passed; that also solves the issue of limited sleeping time on some systems.

For Unix, refactor OSSL_sleep() to use nanosleep() instead of usleep()

2024-05-22T07:59:32Z

usleep() is obsolete since POSIX.1-2001 and removed in POSIX.1-2008, in favor of nanosleep(), which has been present since POSIX.1-2001. The exceptions for DJGPP and TANDEM are preserved. Also, just in case nanosleep() turns out to be unavailable on any Unix machinery that we are unaware of, we allow a revert to using usleep() by defining OPENSSL_USE_USLEEP.

NonStop: Do not call sleep() with a 0 value

This change ensures that sleep(0) is not invoked to cause unexpected duplicate thread context switches when _REENTRANT is specified. Fixes: #24009 Signed-off-by: Randall S.

Correct OSSL_sleep for NonStop PUT model by introducing sleep().

This fix also removes SPT model support as it was previously deprecated. Upcoming threading models on the platform should be supportable without change to this method.
