Hi All,

Can you please run utimes01 test? I see there on x86 and Microblaze this fault.
There is different errno value.

Thanks,
Michal

Michal,

This is a known issue. If you look at the manpages it states the following under the BUGS section:

Linux is not careful to distinguish between the EACCES and EPERM
error returns. On the other hand, POSIX.1-2001 is buggy in its error description for utimes().

utimes01 passes on 2.6.28-13 kernel (Ubuntu 9.04) as well as the 2.6.18 kernel in CentOS 4.

I found that in source code is that second return value too. But anyway thanks for explanation.

Michal,

My x86_32 behaves fine with this Syscall test, may be because it is 2.6.18 kernel as henry said.

Can you send across a patch to update include the above information in the test case itself ?

if POSIX allows for both, then so should LTP
