Description of problem:
When setsockopt is called with IP_DROP_MEMBERSHIP, it should send an igmp leave
message to the router group (220.127.116.11) but it doesn't.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.run ntpd with multicast enabled
2.start a network analyser (e.g: ethereal) and filter on the router group
multicast address 18.104.22.168
3.type "service ntpd stop"
Actual Results: nothing
Expected Results: it should send an igmp leave message
Not sure whether it's a libc or kernel bug
Nothing to do with glibc, it passes setsockopt stright to the kernel.
This bug doesn't exist on a standard mandrake 8.2 with a kernel 2.4.18 and glic
setsockopt is part of libc, so this problem may be due to glibc
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
