Subject: Fix: filter validator: refuse string and star glob input to bitwise operation
X-Git-Url: http://git.efficios.com/?p=deliverable%2Flttng-modules.git;a=commitdiff_plain;h=4ac5fbb7966e7a6ee4a0cb68c49713bc8c05206c

Fix: filter validator: refuse string and star glob input to bitwise operation

The validator refuses input ax=string,bx=unknown, but accepts input
ax=unknown,bx=string. Both inputs should be refused.

The same goes for the error glob input.
