Description Peter Bieringer 2010-04-26 20:11:05 UTC
Final RHEL6 should be also have fixed this issue because of: http://www.redhat.com/rhel/beta/ Next generation networking: comprehensive IPv6 support # rpm -qf `which ping6` iputils-20071127-9.1.el6.i686 # ping6 -c 1000 -f ::1 -F 12345 Flow labels are not supported. LC_ALL=C ping6 -c 1 ::1 ::1 PING ::1(::1) 56 data bytes ping: sendmsg: Invalid argument +++ This bug was initially created as a clone of Bug #583976 +++ Description of problem: ping6 does not support -F flowlabel option Version-Release number of selected component (if applicable): # rpm -qf `which ping6` iputils-20071127-10.fc12.i686 How reproducible: always Steps to Reproduce: # ping6 -c 1000 -f ::1 -F 12345 Actual results: Flow labels are not supported. (no ping) Expected results: Supported Flow Labels Additional info: Kernel 220.127.116.11-70.fc12.i686 # ping6 -c 1000 -f ::1 PING ::1(::1) 56 data bytes --- ::1 ping statistics --- 1000 packets transmitted, 1000 received, 0% packet loss, time 45ms rtt min/avg/max/mdev = 0.007/0.019/5.680/0.193 ms, ipg/ewma 0.045/0.008 ms --- Additional comment from firstname.lastname@example.org on 2010-04-22 13:21:59 EDT --- Perhaps related: https://bugzilla.redhat.com/show_bug.cgi?id=583985 --- Additional comment from email@example.com on 2010-04-23 10:03:51 EDT --- This isn't related to traceroute issue. The flowlabel functionality is disabled by default therefore "Flow labels are not supported" message is printed. Simple enabling doesn't fix it due to problems with headers. I have to investigate it a bit. --- Additional comment from firstname.lastname@example.org on 2010-04-24 06:45:11 EDT --- During investigation, would be nice if you can also look into the next hop option (source routing), which is not working for IPv6 at all: # ping6 -c 1 2001:xxxx:xxxx:65::1 2001:xxxx:xxxx:66:5054:ff:fexx:xxxx PING ipv6-client-b(ipv6-client-b) 56 data bytes ping: sendmsg: Invalid argument IPv4 works (after enabling accept IPv4 source routing on all participating nodes): # ping 10.0.65.1 ipv4-client-b PING ipv4-client-b (10.0.66.2) 56(124) bytes of data. 64 bytes from ipv4-client-b (10.0.66.2): icmp_seq=1 ttl=63 time=2.78 ms LSRR: ipv4-router-c-65 (10.0.65.1)
Comment 2 RHEL Product and Program Management 2010-04-26 21:27:00 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion.
Comment 3 Jiri Skala 2010-04-29 20:08:44 UTC
Flowlabel functionality is disabled using ifdef. This state is probably intentionally because there is no definition of flowlabel structure in glibc. Kernel headers containing necessary definition conflicts with glib. I've asked glibc package owner about future support of flowlabel structure in the original bug (#583976). Currently no answer. I've sent an inquiry to upstream if disabling flowlabel relates to kernel/glibc headers conflicting. I prefer enabling flowlabel if there is sufficient support in glibc.

Red Hat Enterprise Linux 6.0 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you.
