ifup-post: always update nameserver & search entries in /etc/resolv.conf

2017-10-31T12:11:59+00:00

  This is complete rework of how we generate the /etc/resolv.conf.

  Fixes:
   * always update 'nameserver' & 'search' entries when DNS* & DOMAIN
     options (respectively) were updated in ifcfg-* files
   * always update the order of 'nameserver' entries when the order of
     DNS* options was updated
   * always keep /etc/resolv.conf.save as a proper backup - do not
     overwrite it everytime when updating 'nameserver' or 'search'

  Enhancements:
   * added support for DNS3 option (equals to MAXNS value in GLIBC)
   * added logic to process duplicate DNS* options
   * added logic to process randomly omitted DNS* options (e.g. omitting
     DNS1 while specifying DNS2 and/or DNS3 will still work now)

  This work was based on these two RHEL-7.5 BZs:

Fix calling of firewall-cmd in ifup-post/ifdown-post.

2012-10-08T19:47:57+00:00

firewall-cmd has been using combined longopts since 0.2.6

Add quotes to device/zone in the firewalld support.

2012-03-16T13:59:56+00:00

Add support for firewalld zones. (#802415, from )

2012-03-13T21:26:07+00:00

ZONE in an ifcfg file describes the zone an interface should belong to.
Zones can be configured in the firewalld configuration file.

When interfaces are brought up, tell firewalld, if running, to add them
to the proper zone. Similarly, remove them when they're brought down.

Modified from a patch from Jiri Popelka.
