2014-09-09udev: net_setup_link - open ethtool and rtnl connections lazilyTom Gundersen
2014-09-09udev: event - keep one rtnl per worker, rather than per eventTom Gundersen
Creating the rtnl context is cheap, but freeing it may not be, due to synchronous close(). Also drop some excessive logging. We now log about the changing ifname exactly once.

2014-09-08bus: add code to create custom endpoints and set their policyDaniel Mack
Custom endpoints are alternative connection points to a bus, allowing specific policy to be uploaded. Add two functions to bus-kernel. One to create such endpoints, and another one for setting a policy for them.
2014-09-08bus: factor out bus policy itemsDaniel Mack
In order to re-use the policy definitions, factor them out into their own files.

2014-08-28sd-event: simplify sd_event_source_set_name()David Herrmann
free_and_strdup() does exactly the same as sd_event_source_set_name(), use it!
2014-08-28sd-event: name event sources used in librariesTom Gundersen
This should help in debugging failing event sources.
2014-08-28sd-event: use event source name rather than address in debug messagesTom Gundersen

2014-08-28sd-rtnl: log if kernel buffer is overrun as we currently can't handle that caseTom Gundersen
2014-08-28bus: don't skip interfaces in bus_message_map_properties_changed()David Herrmann
Skipping interfaces randomly without the caller specifying it is nasty. Avoid this and let the caller do that themselves.
2014-08-28bus: fix use-after-free in slot-releaseDavid Herrmann
We must not access slot->floating after we possible dropped the last reference to it. Fix all callback-invocations to first check slot->floating and possible disconnect the slot, then release the last reference.
2014-08-27bus: split bus_map_all_properties into multiple helpersDavid Herrmann
The bus_map_all_properties() helper calls org.freedesktop.DBus.Properties.GetAll() on a given target and parses the result according to a given property-table. This simplifies dealing with DBus.Properties significantly. However, the function is blocking and thus not really useful in many situations. This patch extracts the core of this function and adds two new helpers which directly take dbus-messages as arguments. This way, you can issue asynchronous requests and parse the result via these helpers: bus_message_map_all_properties(): This is the same as bus_map_all_properties() but takes the result message from a GetAll() request as argument. You can thus issue an asynchronous GetAll() request and then use this helper once you got the result. bus_message_map_properties_changed(): This function takes a signal-message that was retrieved via a PropertiesChanged signal and then parses it like if you retrieved it via GetAll(). Furthermore, this function returns the number of matched properties that got invalidated by the PropertiesChanged signal, but didn't carry the new value. This way, the caller can issue a new GetAll() request and then parse the result. The old function bus_map_all_properties() is functionally unchanged, but now uses bus_message_map_all_properties() internally.

2014-08-26sd-event: sd_event_prepare - stay in PREPARED if sd_event_wait() indicates ↵Tom Gundersen
that no sources are pending
2014-08-25sd-event: split run into prepare/wait/dispatchTom Gundersen
This will allow sd-event to be integrated into an external event loop, which in turn will allow (say) glib-based applications to use our various libraries, without manually integrating each of them (bus, rtnl, dhcp, ...). The external event-loop should integrate sd-event int he following way: Every iteration must start with a call to sd_event_prepare(), which will return 0 if no event sources are ready to be processed, a positive value if they are and a negative value on error. sd_event_prepare() may only be called following sd_event_dispatch(); a call to sd_event_wait() indicating that no sources are ready to be dispatched; or a failed call to sd_event_dispatch() or sd_event_wait(). A successful call to sd_event_prepare() indicating that no event sources are ready to be dispatched must be followed by a call to sd_event_wait(), which will return 0 if it timed out without event sources being ready to be processed, a negative value on error and a positive value otherwise. sd_event_wait() may only be called following a successful call to sd_event_prepare() indicating that no event sources are ready to be dispatched. If sd_event_wait() indicates that some events sources are ready to be dispatched, it must be followed by a call to sd_event_dispatch(). This is the only time sd_event_dispatch() may be called.
2014-08-21bus: when terminating our bus-actviated services that exit-on-idle send ↵Lennart Poettering
STOPPING=1 via sd_notify() This should fix a race where a service thatis idle drops its name, and is immediately requested by another client, which causes dbus-daemon to ask systemd to activate it again, but since systemd still assumes it is running it won't do anything.
2014-08-20sd-event: add API to access epoll_fdTom Gundersen
This is a prerequisite for integrating sd-event into an external event loop.

2014-08-19memfd: simplify APILennart Poettering
Now, that the memfd stuff is not exported anymore, we can simplify a few things: Use assert() instead of assert_return(), since this is used internally only, and we should be less permissive then. No need to pass an allocated fd back by call-by-reference, we can just directly return it.
2014-08-18bus: map sealed memfds as MAP_PRIVATEDavid Herrmann
Mapping files as MAP_SHARED is handled by the kernel as 'writable' mapping. Always! Even with PROT_READ. Reason for that is, mprotect(PROT_WRITE) could change the mapping underneath and currently there is no kernel infrastructure to add protection there. This might change in the future, but until then, map sealed files as MAP_PRIVATE so we don't get EPERM.
2014-08-18bus-control: Fix cgroup handlingDenis Kenzior
On systems without properly setup systemd, cg_get_root_path returns -ENOENT. This means that busctl doesn't display much information. busctl monitor also fails whenever it intercepts messages. This fix fakes creates a fake "/" root cgroup which lets busctl work on such systems.

2014-08-18bus-util: simplify bus_verify_polkit_async() a bitLennart Poettering
First, let's drop the "bus" argument, we can determine it from the message anyway. Secondly, determine the right callback/userdata pair automatically from what is currently is being dispatched. This should simplify things a lot for us, since it makes it unnecessary to pass pointers through the original handlers through all functions when we process messages, which might require authentication.
2014-08-18sd-bus: add API to query which handler/callback is currently being dispatchedLennart Poettering
2014-08-18memfd: internalize functions, drop sd_memfd typeDaniel Mack
Remove the sd_ prefix from internal functions and get rid of the sd_memfd type. As a memfd is now just a native file descriptor, we can get rid of our own wrapper type, and also use close() and dup() on them directly.
2014-08-18memfd: fix memfd_create() syscall wrapperDaniel Mack
Unlike earlier versions, the syscall only takes 2 arguments in its final version, not 3.
2014-08-18memfd: move code from public library to src/sharedDaniel Mack
Don't expose generic kernel API via libsystemd, but keep the code internal for our own usage.

2014-08-15sd-bus: add API to check if a client has privilegesLennart Poettering
This is a generalization of the vtable privilege check we already have, but exported, and hence useful when preparing for a polkit change. This will deal with the complexity that on dbus1 one cannot trust the capability field we retrieve via the bus, since it is read via /proc/$$/stat (and thus might be out-of-date) rather than directly from the message (like on kdbus) or bus connection (as for uid creds on dbus1). Also, port over all code to this new API.

2014-08-14sd-network: add sd_network_linkg_get_domains()Tom Gundersen
For now this only exposes the domain name (DHCP Option 15), and not the search string (DHCP Option 119), which will be implemented in a follow-up patch.
2014-08-14sd-event: drop _likely_()Tom Gundersen
This is not certain to be likely. Lennart says: a frequent usecase is invoking some function regularly in intervals in such a case every single iteration we'll have to rearm
2014-08-14sd-event: do not arm timers unnecessarilyTom Gundersen
Rather than recalculating the next timeout on every loop, we only do it when something changed.
2014-08-13sd-networkd: rename link_get_state to link_get_setup_stateTom Gundersen
Suggested by Kay and Lennart.
2014-08-13sd-network: /_get_link_/_link_get_/Tom Gundersen
The link is the 'object', so make this in line with our usual naming convention. Suggested by Kay and Lennart.
2014-08-13bus-bloom: Fix bloom filter calculationDenis Kenzior
i is being used incorrectly. It is used to refer to the number of indexes calculated so far (out of k). However, it is also incremented when a new hash key is being used. This means that the results are inconsistent with the desired behavior described in PORTING-DBUS1 document. The expected result is that for the default values of m and k (512, 8) the 1st hash key should produce 4 indexes. The second hash key is used for the next 4 and overall 8 indexes into m are calculated. The current behavior results in 6 indexes being calculated, 4 coming from hash key 1 and 2 others from hash key 5.
2014-08-13sd-network: rename state INITALIZING to PENDING and expose as any other stateTom Gundersen
This is the state when we are waiting for udev to initialize the device, and waiting for libudev and rtnl to be in sync. In the future we probably will also be waiting for nl80211. At this point we do not yet have enough information to know whether or not networkd should be handling the device.
