Comment 1 Frederic Heem 2002-07-01 08:38:25 EDT
Not sure whether it's a libc or kernel bug
Comment 2 Jakub Jelinek 2002-07-01 08:39:46 EDT
Nothing to do with glibc, it passes setsockopt stright to the kernel.
Comment 3 Frederic Heem 2002-07-01 08:41:36 EDT
This bug doesn't exist on a standard mandrake 8.2 with a kernel 2.4.18 and glic
2.2.4
Comment 4 Frederic Heem 2002-07-01 08:44:31 EDT
setsockopt is part of libc, so this problem may be due to glibc
Comment 5 Ulrich Drepper 2003-04-22 00:57:31 EDT
This has nothing to do with glibc.  setsockopt is a simple syscall wrapper.
Comment 6 Bugzilla owner 2004-09-30 11:39:43 EDT
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
persists.

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/
