2014-11-11sd-bus: add sd_bus_message.verify_destination_id and .destination_ptrDaniel Mack
kdbus learned to accept both a numerical destination ID as well as a well-known-name. In that case, kdbus makes sure that the numerical ID is in fact the owner of the provided name and fails otherwise. This allows for race-free assertion of a bus name owner while sending a message, which is a requirement for bus-proxyd. Add two new fields to sd_bus_message, and set the numerical ID to verify_destination_id if bus_message_setup_kmsg() is called for a message with a well-known name. Also, set the destination's name in the kdbus item to .destination_ptr if it is non-NULL. Normal users should not touch these fields, and they're not publicy accessible.

2014-11-05sd-bus: sync up with new kdbus metadata attachment logic (ABI break)Daniel Mack
The metadata logic in kdbus has seen a rework, and the only mandatory change we have to follow for now is that attach_flags in kdbus_cmd_hello is now split into two parts, attach_flags_send and attach_flags_recv.
2014-11-04sd-bus: rename sd_bus_get_server_id() to sd_bus_get_owner_id()Lennart Poettering
In kdbus a "server id" is mostly a misnomer, as there isn't any "server" involved anymore. Let's rename this to "owner" id hence, since it is an ID that is picked by the owner of a bus or direct connection. This matches nicely the sd_bus_get_owner_creds() call we already have.
2014-11-04sd-bus,sd-event: unify error handling of object descriptionsLennart Poettering
a) When getting the description return ENXIO if none is set b) Allow setting a description to NULL c) return ECHILD on fork() like for other calls

2014-11-04sd-event: rename sd_event_source_set_name() to sd_event_source_get_name()Lennart Poettering
To mirror the recent name change of the concept for sd_bus objects, follow the same logic for sd_event_source objects, too.
2014-11-04sd-bus: rename "connection name" to "description" for the sd-bus API tooLennart Poettering
kdbus recently renamed this concept, and so should we in what we expose in userspace.
2014-11-04sd-bus: sync kdbus.h (ABI break)Daniel Mack
Catch up with some changes in kdbus.h: * KDBUS_{ITEM,ATTACH}_CONN_NAME were renamed to KDBUS_{ITEM,ATTACH}_CONN_DESCRIPTION, so the term 'name' is not overloaded as much. * The item types were re-ordered a little so they are lined up to the order of the corresponding KDBUS_ATTACH flags * A new item type KDBUS_ITEM_OWNED_NAME was introduced, designated to store a struct kdbus_name in item->name. KDBUS_ITEM_NAME soley stores data in item->str now * Some kerneldoc fixes
2014-10-31Make bus errno mappings non-staticZbigniew Jędrzejewski-Szmek
__attribute__((used)) is not enough to force static variables to be carried over to a compiled program from a library. Mappings defined in libsystemd-shared.a were not visible in the compiled binaries. To ensure that the mappings are present in the final binary, the tables are made non-static and are given a real unique name by which they can be referenced. To use a mapping defined not in the local compilation unit (e.g. in a library) a reference to the mapping table is added. This is done by including a declaration in the header file. Expected values in test-engine are fixed to reflect the new mappings.
2014-10-31bus: do not segfault on zeros in errno mapping tableZbigniew Jędrzejewski-Szmek
Depending on the link order, holes might appear in the body of the sd_bus_errnomap section. Ignore them. Adds a simple test to print the table to help with debugging such issues in the future.

2014-10-29sd-rtnl: mark nested attributes with the NLA_F_NESTED flagTom Gundersen
The kernel mostly does not check this, but let's be consisntent and allways set it anyway. Based on patch from Susant Sahani.

2014-10-27Revert "sd-bus: check return value of asprintf()"Lennart Poettering
This reverts commit b1543c4c93855b61b40118e9f14a0423dac2e078. We check b->address anyway, no need to check the return value, especially given that the other #ifdef branch don't get the same treatment.
2014-10-24sd-bus: if we don't manage to properly allocate the error message for an ↵Lennart Poettering
sd_bus_error, just go on sd_bus_error_setfv() must initialize the sd_bus_error value to some sensible value and then return a good errno code matching that. If it cannot work at all it should set the error statically to the OOM error. But if it can work half-way (i.e. initialize the name, but not the message) it should do so and still return the correct errno number for it. This effectively reverts 8bf13eb1e02b9977ae1cd331ae5dc7305a305a09
2014-10-23sd-bus: make sd_bus::reply_callbacks a OrderedHashmapMichal Schmidt
The way process_closing() picks the first entry from reply_callbacks and works with it makes it likely that it cares about the order.
2014-10-23sd-daemon,man: ignore missing $WATCHDOG_PIDZbigniew Jędrzejewski-Szmek
Systemd 209 started setting $WATCHDOG_PID, and sd-daemon watch was modified to check for this variable. This means that sd_watchdog_enabled() stopped working with previous versions of systemd. But sd-event is a public library and API and we must keep it working even when a program compiled with a newer version of the libary is used on a system running an older version of the manager. getenv() and unsetenv() are fairly expensive calls, so optimize sd_watchdog_enabled() by not calling them when unnecessary. man: centralize the description of $WATCHDOG_PID and $WATCHDOG_USEC in the sd_watchdog_enabled manpage. It is better not to repeat the same stuff in two places.

2014-10-22sd-bus: fix transition left-overs in sd_bus_get_owner_creds()Daniel Mack
sd_bus_get_owner_creds() was only halfly ported over to _cleanup_bus_creds_unref_.
2014-10-22sd-bus: implement sd_bus_get_owner_creds() for kdbusDaniel Mack
kdbus learned a new ioctl to tell userspace about a bus creator's credentials, which is what we need to implement sd_bus_get_owner_creds() for kdbus. Move the function from sd-bus.c to bus-control.c to be able to reuse the bus_populate_creds_from_items() helper.
2014-10-22sd-bus: rename sd_bus_get_owner_uid(), sd_bus_get_owner_machine_id() and ↵Daniel Mack
sd_bus_get_peer_creds() Clean up the function namespace by renaming the following: sd_bus_get_owner_uid() → sd_bus_get_name_creds_uid() sd_bus_get_owner_machine_id() → sd_bus_get_name_machine_id() sd_bus_get_peer_creds() → sd_bus_get_owner_creds()
2014-10-22sd-bus: factor out creds item iteratorDaniel Mack
We will re-use the code to walk items in order to populate a creds object, so let's factor it out first.
2014-10-22sd-bus: sync kdbus.hDaniel Mack
kdbus learned a new command to query a bus creator's credentials. Sync kdbus.h first, which also renames some struct to more generic terms. That is, however, not an ABI break this time.
2014-10-22sd-bus: assert clock_gettime()'s return valueDaniel Mack
Don't handle clock_gettime() errors gracefully but use assert_se().
2014-10-21sd-bus: sync kdbus.h (API change: switch to absolute timeouts)Daniel Mack
kdbus_msg.timeout_ns now takes an absolute value, based on CLOCK_MONOTONIC, in order to eventually support automatically restarted syscalls. Signed-off-by: Daniel Mack <daniel@zonque.org>
2014-10-21sd-bus: sync kdbus.h (ABI break)Daniel Mack
In kdbus.h, the following details changed: * All commands gained a 'kernel_flags' field to report the flags supported by the driver. Before, this was done in the 'flags' field in a bidirectional way, which turned out to be a problem for the code in sd-bus, as many parts of it reuse the same ioctl struct more than once and consider them to be owned by userspace. * Name listings are now returned by a new struct instead of reusing struct kdbus_cmd_name for that matter. This way, we don't add more unneeded fields to it and make the API cleaner. * 'conn_flags' was renamed to 'flags' in struct kdbus_cmd_hello to make the API a bit more unified.
2014-10-20kdbus: free returned buffer when the memory is no longer neededLukasz Skalski
2014-10-20sd-bus: sync kdbus.h (ABI break)Daniel Mack
kdbus.h now has KDBUS_ATTACH_COMM split into KDBUS_ATTACH_TID_COMM and KDBUS_ATTACH_PID_COMM. The items were split already, so the change in systemd is easy.
2014-10-18sd-bus: sync kdbus.h (ABI break)Daniel Mack
In kdbus.h, the 'features' field has been dropped again. Instead of negotiating features that way, we decided to make the kernel return the set of supported flags in each ioctl struct's .flags field, in both the success and error cases.
2014-10-17Revert "sd-bus: sync kdbus.h (ABI break)"Kay Sievers
This reverts commit 1a2409e262da65a4b0ca8ab18fcf5eabd2d404ca. Support from the kdbus interface was removed. We require memfds to be supported by all clients.
2014-10-14sd-bus: sync kdbus.h (ABI break)Daniel Mack
kdbus learned KDBUS_HELLO_ACCEPT_MEMFD as new connection negotiation flag. Set it by default in systemd for now.
