Solution: use check_basic_command_structure in curve_client_t::decode, also prepare other client mechanisms to use that method by rearranging inheritance hierarchy
Problem: GSSAPI DRAFT code was made conditional on
ZMQ_BUILD_DRAFT_API, but zmq_draft.h duplicates the DRAFT
symbols definitions from zmq.h so this is unnecessary.
Solution: drop the extra ifdefs
Problem: The new GSSAPI NAMESPACE options should have been
added to the DRAFT section of the API so they can be changed
until stabilized.
Solution:
- Move defines to the DRAFT section of zmq.h
- Duplicate them in zmq_draft.h, as is the local custom
- Compile only if defined (ZMQ_BUILD_DRAFT_API)
- Refactor internals slightly to avoid #ifdef hell
Problem: principals are looked up unconditionally
with the GSS_C_NT_HOSTBASED_SERVICE name type.
Solution: Add two new socket options to set the name type
for ZMQ_GSSAPI_PRINCIPAL and ZMQ_GSSAPI_SERVICE_PRINCIPAL:
ZMQ_GSSAPI_PRINCIPAL_NAMETYPE
ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE
They take an integer argument which must be one of
ZMQ_GSSAPI_NT_HOSTBASED (0) - default
ZMQ_GSSAPI_NT_USER_NAME (1)
ZMQ_GSSAPI_NT_KRB5_PRINCIPAL (2)
These correspond to GSSAPI name types of:
GSS_C_NT_HOSTBASED_SERVICE
GSS_C_NT_USER_NAME
GSS_KRB5_NT_PRINCIPAL_NAME

Problem: one call to gss_import_name() includes the terminating
NULL in a gss_buffer_desc.length, and one doesn't.
According to the examples at:
http://docs.oracle.com/cd/E19253-01/816-4863/overview-22/index.html
the NULL should be included in the length.
Solution: Fix one case to include the terminating NULL in the length.
Problem: if client sets ZMQ_GSSAPI_PRINCIPAL to a name
for which credentials cannot be obtained, authentication
proceeds with default credentials.
Solution: Before initializing the security context, check
whether there was a failed attempt to acquire credentials
for a specific principal and bail out if so.
Fixes#2531
Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.
Solution: specify these grants in the header of each source file.
