[release-4.17] OCPBUGS-51116: update resolv.conf every time on bootstrap node #9504
base: release-4.17
Are you sure you want to change the base?
Conversation
Currently, /etc/resolv.conf on bootstrap node is updated only once. Because of this, /etc/resolv.conf may be incorrect due to timing issues. By this change, /etc/resolv.conf is updtaed at all "up", "dhcp4-update", "dhcp6-update" events.
Currently, /etc/resolv.conf on bootstrap node is updated only once. Because of this, /etc/resolv.conf may be incorrect due to timing issues. By this change, /etc/resolv.conf is updtaed at all "up", "dhcp4-update", "dhcp6-update", "dns-change" events. "dns-change" event is supposed to be enough if it works, but "dns-change" is a new function[1] of NetworkManager. Other events, "up", "dhcp4-update" and "dhcp6-update", are kept for environments where "dns-change" doesn't works. [1] NetworkManager starting from 1.42.2-12.el9_2 and 1.36.0-17.el8_6 adds a new event `dns-change` which is fired whenever a change to the DNS configuration happens.
