core,network: major per-object logging rework

This changes log_unit_info() (and friends) to take a real Unit* object
insted of just a unit name as parameter. The call will now prefix all
logged messages with the unit name, thus allowing the unit name to be
dropped from the various passed romat strings, simplifying invocations
drastically, and unifying log output across messages. Also, UNIT= vs.
USER_UNIT= is now derived from the Manager object attached to the Unit
object, instead of getpid(). This has the benefit of correcting the
field for --test runs.

Also contains a couple of other logging improvements:

- Drops a couple of strerror() invocations in favour of using %m.

- Not only .mount units now warn if a symlinks exist for the mount
  point already, .automount units do that too, now.

- A few invocations of log_struct() that didn't actually pass any
  additional structured data have been replaced by simpler invocations
  of log_unit_info() and friends.

- For structured data a new LOG_UNIT_MESSAGE() macro has been added,
  that works like LOG_MESSAGE() but prefixes the message with the unit
  name. Similar, there's now LOG_LINK_MESSAGE() and
  LOG_NETDEV_MESSAGE().

- For structured data new LOG_UNIT_ID(), LOG_LINK_INTERFACE(),
  LOG_NETDEV_INTERFACE() macros have been added that generate the
  necessary per object fields. The old log_unit_struct() call has been
  removed in favour of these new macros used in raw log_struct()
  invocations. In addition to removing one more function call this
  allows generated structured log messages that contain two object
  fields, as necessary for example for network interfaces that are
  joined into another network interface, and whose messages shall be
  indexed by both.

- The LOG_ERRNO() macro has been removed, in favour of
  log_struct_errno(). The latter has the benefit of ensuring that %m in
  format strings is properly resolved to the specified error number.

- A number of logging messages have been converted to use
  log_unit_info() instead of log_info()

- The client code in sysv-generator no longer #includes core code from
  src/core/.

- log_unit_full_errno() has been removed, log_unit_full() instead takes
  an errno now, too.

- log_unit_info(), log_link_info(), log_netdev_info() and friends, now
  avoid double evaluation of their parameters

btrfs-util: be more careful when invoking btrfs file system ioctls

directory, we should not issue btrfs ioctls on it, since it might end up
in a device driver or similar (note that DRM for example uses the same

better to be safe than sorry.

2 years agobus: implement bus_path_{en,de}code_unique()
David Herrmann [Fri, 10 Apr 2015 15:44:30 +0000 (17:44 +0200)]
bus: implement bus_path_{en,de}code_unique()

Whenever we provide a bus API that allows clients to create and manage
server-side objects, we need to provide a unique name for these objects.
There are two ways to provide them:
  1) Let the server choose a name and return it as method reply.
  2) Let the client pass its name of choice in the method arguments.

The first method is the easiest one to implement. However, it suffers from
a race condition: If a client creates an object asynchronously, it cannot
destroy that object until it received the method reply. It cannot know the
name of the new object, thus, it cannot destroy it. Furthermore, this
method enforces a round-trip. If the client _depends_ on the method call
to succeed (eg., it would close() the connection if it failed), the client
usually has no reason to wait for the method reply. Instead, the client
can immediately schedule further method calls on the newly created object
(in case the API guarantees in-order method-call handling).

The second method fixes both problems: The client passes an object name
with the method-call. The server uses it to create the object. Therefore,
the client can schedule object destruction even if the object-creation
hasn't finished, yet (again, requiring in-order method-call handling).
Furthermore, the client can schedule further method calls on the newly
created object, before the constructor returned.

There're two problems to solve, though:
  1) Object names are usually defined via dbus object paths, which are
     usually globally namespaced. Therefore, multiple clients must be able
     to choose unique object names without interference.
  2) If multiple libraries share the same bus connection, they must be
     able to choose unique object names without interference.

The first problem is solved easily by prefixing a name with the
unique-bus-name of a connection. The server side must enforce this and
reject any other name.
The second problem is solved by providing unique suffixes from within
sd-bus. As long as sd-bus always returns a fresh new ID, if requested,
multiple libraries will never interfere. This implementation re-uses
bus->cookie as ID generator, which already provides unique IDs for each
bus connection.

This patch introduces two new helpers:
  bus_path_encode_unique(sd_bus *bus,
                         const char *prefix,
                         const char *sender_id,
                         const char *external_id,
                         char **ret_path);
    This creates a new object-path via the template
    '/prefix/sender_id/external_id'. That is, it appends two new labels to
    the given prefix. If 'sender_id' is NULL, it will use
    bus->unique_name, if 'external_id' is NULL, it will allocate a fresh,
    unique cookie from bus->cookie.

  bus_path_decode_unique(const char *path,
                         const char *prefix,
                         char **ret_sender,
                         char **ret_external);
    This reverses what bus_path_encode_unique() did. It parses 'path' from
    the template '/prefix/sender/external' and returns both suffix-labels
    in 'ret_sender' and 'ret_external'. In case the template does not
    match, 0 is returned and both output arguments are set to NULL.
    Otherwise, 1 is returned and the output arguments contain the decoded
    labels.

Note: Client-side allocated IDs are inspired by the Wayland protocol
      (which itself was inspired by X11). Wayland uses those IDs heavily
      to avoid round-trips. Clients can create server-side objects and
      send method calls without any round-trip and waiting for any object
      IDs to be returned. But unlike Wayland, DBus uses gobally namespaced
      object names. Therefore, we have to add the extra step by adding the
      unique-name of the bus connection.
