SBUS: Chown the sbus socket if needed

2014-10-22T13:44:17+00:00

When setting up the sbus server, we might need to chown the sbus socket
to make sure non-root peers, running as the SSSD user are able to access
the file.

SSSD: Add the options to specify a UID and GID to run as

2014-10-20T19:43:40+00:00

Adds new command line options --uid and --gid to all SSSD servers,
making it possible to switch to another user ID if needed.

So far all code still runs as root.

sbus: Add the sbus_request_parse_or_finish() method

2014-03-14T12:42:31+00:00

Some DBus types returned from dbus_message_get_args() require memory
to be released when done. We automatically attach these to the talloc
struct sbus_request memory context in this function.

This accepts varargs similar to dbus_message_get_args(), which are
rather awkward. However instead of reworking them completely, future
generated marshalling code will replace most uses of these varargs.

If parsing the dbus message fails, then it responds to the DBus caller
with an appropriate error such as o.f.D.Error.InvalidArgs. In these
cases (ie: when it returns FALSE) the sbus_request is finished.

Migrated some, but not all, uses of dbus_message_get_args() to the
new function. Some instances have uncommon semantics such as terminating
the connection upon failure to parse a message.

sbus: Refactor how we export DBus interfaces

2014-03-14T12:42:20+00:00

Most importantly, stop using per connection private data. This doesn't
scale when you have more than one thing exporting or exported on a
connection.

Remove struct sbus_interface and expand sbus_conn_add_interface()
function. Remove various struct sbus_interface args to connection
initialization functions and make callers use sbus_conn_add_interface()
directly. The old method was optimized for exporting one interface
on a connection. We'll have connections that export zero, one or more
interfaces.

To export an interface on a DBus server, call sbus_conn_add_interface()
from within the sbus_server_conn_init_fn. To export an interface on
a DBus client, call sbus_conn_add_interface() after sbus_new_connection()
returns.

As before struct sbus_interface represents an object exported via DBus.
However it is now talloc allocated. One can set instance data on the
struct sbus_interface. This instance data is passed to the various
handlers and used in their implementation.

However, we now have type safe interface exporting in the various
high level sss_process_init() sss_monitor_init() and so on.

Introspection support was not in use, and is now gone until we
implement it using the metadata (future patch).

sbus: Add struct sbus_request to represent a DBus invocation

2014-03-14T12:42:17+00:00

struct sbus_request represents a request from a dbus client
being handled by a dbus server implementation. The struct
contains the message, connection and method (and in the
future teh property) which is being requested.

In the future it will contain caller information as well.

sbus_request is a talloc memory context, and is a good place to
attach any allocations and memory specific to the request.

Each handler accepts an sbus_request. If a handler returns
EOK, it is assumed that the handler will finish the request.
Any of the sbus_request_*finish() methods can be used to
complete the request and send back a reply.

sbus_request_return_and_finish() uses the same argument
varargs syntax as dbus_message_append_args(), which isn't
a great syntax. Document it a bit, but don't try to redesign:
The marshalling work (will follow this patch set) will remove
the need to use varargs for most DBus implementation code.

This patch migrates the monitor and data provider dbus code
to use sbus_request, but does not try to rework the talloc
context's to use it.

sbus: Use constants to make dbus calls

This allows us to remove duplicated information, and have the
compiler check that when an method name is changed or removed
the callers are updated.

sbus: Rework sbus to use interface metadata and vtables

2014-02-24T10:14:59+00:00

Previous commits added support for interface metadata and
handler vtables. This commit ports sbus_dbus_connection to
use them.

Port the internal uses of dbus to use the new scheme in a
very minimal way. Further cleanup is possible here.

This commit provides basic definitions of the internal
dbus interfaces. The interfaces aren't fully defined, as the
handlers will continue to unpack manually, and often overload
DBus methods with different arguments (which is rather
unorthodox, but not the end of the world).
