Description Lawrence Lim 2008-03-31 21:59:54 EDT
Description of problem:
Attempt to run dhcp6c in debug mode will experience the application going into
an infinite loop. Similar experience has been observed in F-9 as well.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. create /tmp/dhcp6c.conf

interface eth1 {
 send rapid-commit;
 request domain-name-servers;
 iaid 1111;
 address {

2. dhcp6c -dDf -c tmp/dhcp6c.conf eth1
Actual results:

Apr/01/2008 09:56:08 found an interface eth1 harware 00:1d:0f:19:59:fc
Apr/01/2008 09:56:08 saved generated DUID to /var/lib/dhcpv6/dhcp6c_duid
Apr/01/2008 09:56:08 set client ID
Apr/01/2008 09:56:08 set opt_8
Apr/01/2008 09:56:08 set rapid commit
Apr/01/2008 09:56:08 set IA_NA iaidinfo: iaid 420420864 renewtime 0 rebindtime 0
Apr/01/2008 09:56:08 set opt_3
Apr/01/2008 09:56:08 set option request
Apr/01/2008 09:56:08 send dst if eth1 addr is ff02::1:2%eth1 scope id is 3
Apr/01/2008 09:56:08 send solicit to ff02::1:2%eth1
Apr/01/2008 09:56:08 DUID is 00:01:00:01:47:f1:96:30:10:b1:eb:39:ff:7f, DUID_LEN
is 14
Apr/01/2008 09:56:08 removing ID (ID: 00:01:00:01:47:f1:96:30:10:b1:eb:39:ff:7f)
Apr/01/2008 09:56:08 DUID is , DUID_LEN is 0
Apr/01/2008 09:56:08 reset a timer on eth1, state=SOLICIT, timeo=3, retrans=8268

Expected results:
Should not be stuck in a loop

Comment 4 Lawrence Lim 2008-05-30 01:43:14 EDT
Debug mode in client has been fixed with the test build dhcpv6-1.0.10-5.el5.
Would you like to include this bug in z-stream update?
Comment 9 David Cantrell 2008-07-23 17:22:49 EDT
You're passing the -f switch, which keeps dhcp6c running in the foreground.  Is that the intention?  I am 
running it here using your command line and it's working fine, except dhcp6c stays in the foreground 
rather than going to the background.
