733299 – Rescan and show network devices after clearing blacklist in linuxrc

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jan Stodola 2011-08-25 11:58:23 UTC

Created attachment 519825 [details]
proposed patch

Description of problem:
When one is running installation with the "cio_ignore=all,!0.0.0009" kernel parameter and CMS config file is not used to configure devices, linuxrc offers the choice to clear blacklist. But after clearing the blacklist, user has to manually enter all values to configure the device.
It would be nice to rescan and show devices discovered after clearing the blacklist.

With anaconda-13.21.134-1.el6, user see following:
...
Scanning for available network devices... 
Autodetection found 0 devices. 
Note: There is a device blacklist active! (Clearing might take long)
c) clear blacklist, m) manual config, r) rescan, s) shell: 
c
Clearing device blacklist... 
/init: line 491: nettable: bad array subscript 
 
* NOTE: To enter default or empty values press enter twice. * 
 
Network type (qeth, lcs, ctc, ? for help). Default is qeth:

With modified linuxrc script showing devices after clearing the blacklist:

Proposed patch is included in attachment.
The patch also fixes following error message:
...
/init: line 491: nettable: bad array subscript 
...

Version-Release number of selected component (if applicable):
anaconda-13.21.134-1.el6

How reproducible:
always

Steps to Reproduce:
1. do not provide any CMS config file for z/VM guest
2. start the installation with the "cio_ignore=all,!0.0.0009" kernel parameter
3. clear blacklist when asked
4. configure network device
  
Actual results:
user has to enter network type and device numbers manually

Expected results:
rescan network devices and display list of found devices
