BIG-IP LTM(all modules)

Known Affected Versions:
11.4.0, 11.4.1

Symptoms

When executing an ltm policy with a condition on http-uri, the tmm would emit ERR_ARG and the condition would not match if the URI is large (> 1450 bytes).

Impact

The policy does not work correctly and log messages are written into /var/log/tmm.

Conditions

This would happen with: - a virtual which uses a policy - that policy has a condition on http-uri - the request contains a large URI (larger than the MSS).

Workaround

None.

Fix Information

The tmm now correctly processes large URIs when evaluating conditions of type http-uri in an ltm policy.
