Description of problem:
IPv6 stateless autoconfig ("Automatic neighbor discovery") doesn't work when
setting up TCP/IP for a network install of Fedora 7 test 2 (either i386 or
X86_64). It looks like it is trying to do DHCPv6 instead; selecting DHCPv6 gives
identical results. There is no DHCP/DHCPv6 or IPv4 connectivity on this
interface. Here's the relevant anaconda log:
14:20:35 INFO : need to set up networking
14:20:35 INFO : going to pick interface
14:20:41 INFO : going to do getNetConfig
14:20:41 INFO : eth1 is not a wireless adapter
14:20:55 INFO : DHCP eth1 - bringing link UP - 11043 65
14:20:55 INFO : DHCPv6: NIC: 0x93e5a0 eth1 0x93e3f0
14:21:41 INFO : DHCPv6 eth1 - state: DHC_TIMEDOUT
14:21:41 ERROR : DHCPv6 eth1 - TIMED OUT - failure.
(I also tried with eth0 and got the same result)
Version-Release number of selected component (if applicable):
Fedora 7 test 2
Steps to Reproduce:
1. Start anaconda from CD (boot.iso)
2. Choose HTTP install source
3. Choose network interface
4. At "Configure TCP/IP" dialog, uncheck "Enable IPv4 support"
5. Leave IPv6 and "Automatic neighbor discovery" enabled, and select "OK"
Box appears that says "Sending request for IP information for eth1". The box
disappears after a minute, and the "Configure TCP/IP" dialog is still there.
Should automatically get network prefix from radvd server
I should also mention that stateless autoconfig ultimately does seem to work,
but only if I choose "Manual configuration" and enter an arbitrary address
within my /64. See Bug 230949 for more info.
Fixed in rawhide. Thanks. (reassigned back to anaconda since that's where the
*** Bug 231502 has been marked as a duplicate of this bug. ***
I tried the boot.iso from this morning's build and it's still broken. When I hit
OK at the "Configure TCP/IP" dialog, I see a messagebox appear for an instant
and then I'm back at the same dialog. This is what appears in anaconda's log
when I do that:
CRITICAL: dhcp_nic: both DISABLE_DHCPv6 and DISABLE_DHCv4 (sic) set.
Corner case I wasn't trapping in doDhcp() in net.c in loader. If we reach
doDhcp() and the user has caused both DHCP clients to be disabled, I return and
push you to the manual network configuration screens (if appropriate).
Fixed now in rawhide. Thanks for the feedback.
