Fixed In:

Opened: Dec 03, 2015
Severity: 3-Major

Symptoms

iRules that contain strings matching a file name reference might be modified when upgrading to file objects.

Impact

Upgrade removes the quotes and slash. This modifies the behavior of the iRule, rendering it ineffective.

Conditions

This occurs when upgrading from 10.x to 11.0.0 through 12.0.0, when there is a file object with some name, for example, name.png, and in an iRule, there is a reference to the file object: "/name.png". After the upgrade, "/<name.png>" will be modified to name.png (that is, no quotes or slash).

Workaround

Make sure there are no file objects of the same name as those referenced with quotes and slash characters in any iRule.

Fix Information

Upgrades no longer removes quotes and slashes from iRule references when there are file objects of the same name.

Behavior Change
