This change fixes a potential denial-of-service bug with the
server, setting a default timeout for all server sockets. This
allows the server to drop hung connections without blocking
forever. The interrupt triggered during accept calls is expected
and is now handled appropriately. Server unit tests have been
updated to reflect this change.
Closes#430
This change updates the server, adding in support for customizing
the backend storage file used to store all server data. The server
currently uses a simple SQLite database for storage. Prior versions
of the server kept this database file in /tmp, to emphasize the
testing focus of the server. This change loosens that restriction,
now allowing users to customize where the database file lives. A
new configuration option, 'database_path', has been added that will
override the default /tmp location for the database file. This
value can also be passed in if invoking the server via script using
the '-d' flag.
This change updates the server, integrating policy file monitoring
and restructuring the engine. The top-level server entity now
handles loading policy files using the PolicyDirectoryMonitor
subprocess. A shared memory dictionary is used to share newly
modified policy data across the session threads managed by the
server and used by the engine. The legacy policy loading code in
the engine has been removed.
Unit tests have been added and modified for both the server and
engine to verify the functionality of these modifications.
This change fixes violations of E722, the use of except without
specifying an exception type. For now the high-level Exception
class is used as a generic catchall. In the future these cases
will be updated to handle the specific exceptions expected.
This change adds a logging level configuration option for the
server, allowing the admin to control what server activity gets
collected for logging. Unit tests have been added and updated to
cover this new configuration setting.
This change adds a server configuration option, tls_cipher_suites,
allowing the server admin to specify a list of cipher suites to be
used when establishing TLS connections with clients. The custom
list supports both cipher suite specification and OpenSSL suite
naming conventions. The list is filtered through a KMIP-approved
set of cipher suites, and then through a set of cipher suites
suitable for the configured authentication suite. Additional debug
logging has been added to the server to provide transparency on
this process.
This change adds a server configuration option to control the
enforcement of TLS certificate client authentication. Before,
client TLS certificates had to include the extended key usage
extension with the clientAuth bit set to be used as sources of
client identity. The new configuration option,
enable_tls_client_auth, allows server admins to enable/disable
this requirement. The configuration setting is optional and the
server defaults to the original enforcing behavior if it is not
set. Admins must explicitly set the option to False to disable
enforcement.
This change fixes a bug introduced with the addition of Python3.5
support. In Python3.5, SIGINT is silently ignored for system calls
(e.g., socket.accept) if the SIGINT signal handler does not raise
an exception. This causes the server to delay shutdown when
receiving SIGINT until after a new connection has been made. This
change updates the server's SIGINT signal handler to raise the
correct exception and updates the error handling code while serving
connections to account for this change in SIGINT processing. This
allows the server to shutdown immediately upon receiving SIGINT.
The server unit tests are updated to account for this change.
This change updates how the built-in open function is mocked in
the PyKMIP server test suite. On some platforms the old approach
was insufficient. This change explicitly references the builtins
module for Python3+, removing the old module-based mock.
This change fixes a bug with the server where the server would
prematurely shutdown upon receiving a client connection using an
invalid certificate. The server will now withstand bad client
connections. The impacted server unit tests have been updated to
reflect the bug fix.
This change adds support for dynamic operation policy loading.
The server config file now supports a 'policy_path' option that
points to a filesystem directory. Each file in the directory
should contain a JSON policy object. The KMIP server will scan
this directory and attempt to load all valid policies it finds.
The results of this process will be logged.
This change adds the KmipServer, the front-end of the KMIP software
server. The KmipServer is in charge of loading configuration settings,
creating all major server components, and serving and managing client
connections. A KmipServerConfig tool is included to handle configuration
settings. Test cases for all new code are included.
