      The files that make up the socket module make use of types like SSLManagerInterface and SSLConnectionInterface that are defined in the library ssl_manager module. However, the socket library doesn't link to the ssl_manager.

      For static builds, this isn't a problem. And for a number of dynamic builds, we happen to get away with it. But not for all builds. In particular, for the "!{A,UB}SAN Enterprise Ubuntu 18.04 DEBUG" build with the "--link-model=dynamic" flag, we find that some tests (such as transport_test) fail to link, presumably because their link graph include socket but not ssl_manager.

      The goal of this task is to clarify the relationship between these two modules, and to make changes to scons and do whatever code movement/refactoring is needed to get the "!{A,UB}SAN Enterprise Ubuntu 18.04 DEBUG" build with the "--link-model=dynamic" flag working.

      Take a look at SERVER-48736 to see an example of a similar issue involving the query_exec module and the index_access_methods module and how the issue was fixed.

      It looks like this might be the last issue blocking SERVER-48892 .
