This can lead to problems when there is intermittent connectivity to an NTP server over a given IP protocol. This changes DHCP update processing such that it only overwrites server addresses for the same protocol. It also does the same for IPv4 NTP server addresses when processing a DHCPv6 update. The logging for processing DHCP and DHCPv6 updates are now a bit more useful. Tests: - On a network with DHCP and DHCPv6 configure differing numbers (0-3) of NTP servers on each protocol. Ensure that as updates are processed the list of 3 LWIP NTP servers is updated as expected. - On a network with intermittent IPv6 connectivity ensure that with both IPv4 and IPv6 servers configured via DHCP that NTP updates are requested over IPv4 even if it is not listed first. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Sun 29 Sep 2019 05:00:29 PM UTC Name: 0001-sntp-Don-t-over-write-IPv6-NTP-server-when-processin.patch Size: 4KiB By: davefiddes <http://savannah.nongnu.org/patch/download.php?file_id=47586> _______________________________________________________ Reply to this item at: <https://savannah.nongnu.org/patch/?9856> _______________________________________________ Message sent via Savannah https://savannah.nongnu.org/
