Filtee Processing

The runtime linker's processing of a filter defers loading a filtee until a filter symbol is referenced. This implementation is analogous to the filter performing a dlopen(3C), using mode RTLD_LOCAL, on each of its filtees as the filtee is required. This implementation accounts for differences in dependency reporting that can be produced by tools such as ldd(1).

The link-editor's –z loadfltr option can be used when creating a filter to cause the immediate processing of its filtees at runtime. In addition, the immediate processing of all filtees within a process, can be triggered by setting the LD_LOADFLTR environment variable to any value.
