Problem with close_range (util-linux)

[Lukasz Majewski]

Hi Adhmerval,

I'm now trying to integrate the -master glibc to Yocto/OE, to build the
Y2038 distribution (previously I had the DUT glibc installed in /opt).

I've found some problem with close_range syscall on util-linux.

It detects if the close_range is available (with autotools) and then
tries to use it in lib/fileutils.c

The problem is that it has different signature:
-       close_range(STDERR_FILENO + 1, ~0U);
+       close_range(STDERR_FILENO + 1, ~0U, 0);

than the one from glibc.

I've also noted that close_range has the GLIBC symbol version from 2.34
release, so this is not yet a big issue, but:

1. Shall we handle this case in glibc at all?

or

2. Wait for 2.34 release and then util-linux shall also adjust to the
new, proper signature of close_range?

Those are just my lose thoughts, as the fix for now is pretty
straightforward. However, I would like to fix as much things as
possible until we release the 2.34.

Thanks in advance for any input :-)

Best regards,

Lukasz Majewski
