Description Andrei Tatar 2013-11-11 10:41:11 EST
Description of problem:

When specifying an nfs path containing an ipv6 address, either on the kernel cmdline as


or in the kickstart file as the path for stage2:

nfs --server [fc00::xxxx:xxxx] --dir /opt/opsware/boot/kickstart/rhel60x64

the nfs address is parsed wrong.

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

anaconda 13.21.195 , possibly earlier as well

How reproducible:


Steps to Reproduce:
1. Boot RHEL 6.4 install cd with kernel argument "ks=nfs:[ipv6address]:/path/to/ks"
2. Wait for anaconda to load
3. Anaconda complains of not being able to load the kickstart file, and logs show malformed parsing of the url

Actual results:

For an example ipv6 address of [fc00:123:1:0:250:56ff:fe00:1234]

The NFS url gets parsed as:

Expected results:

Same example address:


Additional info:

The most likely culprit is
void parseNfsHostPathOpts (char *url, char **host, char **path, char **opts)
from loader/nfsinstall.c in the anaconda source tree. The parsing doesn't take into consideration the case in which host is an ipv6 address.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

I can confirm this is a parsing bug (see screenshot) and minor issue.  I can be reproduce with nfs-over-ipv6 but not http-over-ipv6 or https-over-ipv6.
