Comment 1 Frederic Heem 2002-07-01 12:38:25 UTC
Not sure whether it's a libc or kernel bug

Comment 2 Jakub Jelinek 2002-07-01 12:39:46 UTC
Nothing to do with glibc, it passes setsockopt stright to the kernel.

Comment 3 Frederic Heem 2002-07-01 12:41:36 UTC
This bug doesn't exist on a standard mandrake 8.2 with a kernel 2.4.18 and glic

Comment 4 Frederic Heem 2002-07-01 12:44:31 UTC
setsockopt is part of libc, so this problem may be due to glibc

Comment 5 Ulrich Drepper 2003-04-22 04:57:31 UTC
This has nothing to do with glibc.  setsockopt is a simple syscall wrapper.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
