85286beb5b Address inconsistent-return-statements
Pylint warns about inconsistent return statements when some paths of a
function return None implicitly. Make all implicit returns either
explicit or raise a proper exception.

Block PyOpenSSL to prevent SELinux execmem in wsgi
Some dependencies like Dogtag's pki.client library and custodia use
python-requsts to make HTTPS connection. python-requests prefers
PyOpenSSL over Python's stdlib ssl module. PyOpenSSL is build on top
of python-cryptography which trigger a execmem SELinux violation
in the context of Apache HTTPD (httpd_execmem).

When requests is imported, it always tries to import pyopenssl glue
code from urllib3's contrib directory. The import of PyOpenSSL is
enough to trigger the SELinux denial.

Block any import of PyOpenSSL's SSL module in wsgi by raising an
ImportError. The block is compatible with new python-requests with
unbundled urllib3, too.

ab9d1e75fc logging: do not reference loggers in arguments and attributes
Remove logger arguments in all functions and logger attributes in all
objects, with the exception of API object logger, which is now deprecated.
Replace affected logger calls with module-level logger calls.

0562359f31 wsgi, oddjob: remove needless uses of Env
Do not use custom Env instance to determine the debug level to use for the
IPA API object - the IPA API object can properly determine the configured
debug level on its own.

1e6a204b43 Set explicit confdir option for global contexts
Some API contexts are used to modify global state (e.g. files in /etc
and /var). These contexts do not support confdir overrides. Initialize
the API with an explicit confdir argument to paths.ETC_IPA.

The special contexts are:

* backup
* cli_installer
* installer
* ipctl
* renew
* restore
* server
* updates

The patch also corrects the context of the ipa-httpd-kdcproxy script to
'server'.

9753fd4230 Tweak the session auth to reflect developer consensus.
* Increase the session ID from 48 random bits to 128.

* Implement the sesison_logout RPC command. It permits the UI to send
  a command that destroys the users credentials in the current
  session.

* Restores the original web URL's and their authentication
  protections. Adds a new URL for sessions /ipa/session/json. Restores
  the original Kerberos auth which was for /ipa and everything
  below. New /ipa/session/json URL is treated as an exception and
  turns all authenticaion off. Similar to how /ipa/ui is handled.

* Refactor the RPC handlers in rpcserver.py such that there is one
  handler per URL, specifically one handler per RPC and AuthMechanism
  combination.

* Reworked how the URL names are used to map a URL to a
  handler. Previously it only permitted one level in the URL path
  hierarchy. We now dispatch on more that one URL path component.

* Renames the api.Backend.session object to wsgi_dispatch. The use of
  the name session was historical and is now confusing since we've
  implemented sessions in a different location than the
  api.Backend.session object, which is really a WSGI dispatcher, hence
  the new name wsgi_dispatch.

* Bullet-proof the setting of the KRB5CCNAME environment
  variable. ldap2.connect already sets it via the create_context()
  call but just in case that's not called or not called early enough
  (we now have other things besides ldap which need the ccache) we
  explicitly set it early as soon as we know it.

* Rework how we test for credential validity and expiration. The
  previous code did not work with s4u2proxy because it assumed the
  existance of a TGT. Now we first try ldap credentials and if we
  can't find those fallback to the TGT. This logic was moved to the
  KRB5_CCache object, it's an imperfect location for it but it's the
  only location that makes sense at the moment given some of the
  current code limitations. The new methods are KRB5_CCache.valid()
  and KRB5_CCache.endtime().

* Add two new classes to session.py AuthManager and
  SessionAuthManager. Their purpose is to emit authication events to
  interested listeners. At the moment the logout event is the only
  event, but the framework should support other events as they arise.

* Add BuildRequires python-memcached to freeipa.spec.in

* Removed the marshaled_dispatch method, it was cruft, no longer
  referenced.

 * Change license blobs in source files to mention GPLv3+ not GPLv2 only
 * Add GPLv3+ license text
 * Package COPYING not LICENSE as the license blobs (even the old ones)

897b296a69 Make the server log level more configurable, not defaulting to debug.
This disables debug output in the Apache log by default. If you want
increased output create /etc/ipa/server.conf and set it to:

[global]
debug=True

If this is too much output you can select verbose output instead:

[global]
debug=False
verbose=True

ccaf537aa6 Handle errors raised by plugins more gracefully in mod_wsgi.
This started as an effort to display a more useful error message in the
Apache error log if retrieving the schema failed. I broadened the scope
a little to include limiting the output in the Apache error log
so errors are easier to find.

This adds a new configuration option, startup_traceback. Outside of
lite-server.py it is False by default so does not display the traceback
that lead to the StandardError being raised. This makes the mod_wsgi
error much easier to follow.
