"If both tv_nsec fields are set to UTIME_OMIT, no ownership or permissions check shall be performed for the file, but other error conditions may still be detected (including [EACCES] errors related to the path prefix)." Note the "may". However, under ERRORS, there are "shall fail" errors that would apply under the condition where both times are UTIME_OMIT. Desired Action: Clarify whether these errors are required if both times are UTIME_OMIT. Either add exceptions to the error conditions (e.g. "and not both tv_nsec fields are set to UTIME_OMIT") or replace the "may" in the description with appropriate wording not to imply that these errors are optional. Note: Linux kernel does not detect any errors in the case where both are UTIME_OMIT. I'm not aware of what other implementations do. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2019-08-16 22:45 dalias New Issue 2019-08-16 22:45 dalias Name => Rich Felker 2019-08-16 22:45 dalias Organization => musl libc 2019-08-16 22:45 dalias Section => utimensat/futimens 2019-08-16 22:45 dalias Page Number => ? 2019-08-16 22:45 dalias Line Number => ? ======================================================================
