Module DataFlow
Provides a library for local (intra-procedural) and global (inter-procedural) data flow analysis: deciding whether data can flow from a source to a sink.
Unless configured otherwise, flow means that the exact value of
the source may reach the sink. We do not track flow across pointer
dereferences or array indexing. To track these types of flow, where the
exact value may not be preserved, import
semmle.code.go.dataflow.TaintTracking.
To use global (interprocedural) data flow, extend the class
DataFlow::Configuration as documented on that class. To use local
(intraprocedural) data flow, invoke DataFlow::localFlow or
DataFlow::LocalFlowStep with arguments of type DataFlow::Node.
