[LTP] [PATCH v3] gethostname02: Accept EOVERFLOW on alpha

[panzhe]

Hi Cyril,

Thanks for your review.

The ENAMETOOLONG note in man describes the mainstream glibc implementation based on uname(2), but alpha has its own arch-specific implementation calling raw gethostname syscall and returning EOVERFLOW.
Alpha glibc source:
https://codebrowser.dev/glibc/glibc/sysdeps/unix/sysv/linux/alpha/gethostname.c.html

POSIX does not specify required errno here, this is existing upstream glibc behavior. I suggest accepting both errnos to resolve alpha test failures.


Regards,
