Opened: Jan 30, 2017
Severity: 3-Major

Symptoms

When you upgrade from an affected version, the config gets saved before moving to the new version, thus dropping the enclosing quotes and causing a load failure when booting into the new version.

Impact

Configuration fails to load.

Conditions

Configuration where monitor string contains \" (backslash double-quote) but does not contain one of the following characters: ' (single quote), | (pipe), { (open brace), } (close brace), ; (semicolon), # (hashtag), literal newline, or literal space.

Workaround

Manually edit each string in the BIG-IP_gtm.conf to include enclosing quotes in order to get the config to load the first time.

Fix Information

Configs load successfully after upgrade. Surrounding quotes, if missing, are added to strings in the BIG-IP_gtm.conf file after upgrade. For example: \"service_status\":\"on\".+\"maintenance\":\"off\" in the recv, send recv-disable and username fields. Output of list gtm monitor and bigip.conf match. Reloading the same config via tmsh does not cause unintentional changes, such as losing a level of escape in monitor strings.
