2015-03-02sd-bus: sync kdbus.h (ABI break)Daniel Mack
After some reconsideration, we decided to move the binary protocol back to 64-bit wide UIDs and GIDs. After all, it should be possible to redefine [gu]id_t to uint64_t and things should continue to work. As we want to avoid such data types in kdbus.h, let's move back to 64-bit values and be safe. In sd-bus, we have to do a translation between uint64_t and gid_t now for supplementary gids. Some inline comments have also been updated in kdbus upstream.

Follow two small changes in the kdbus API: * Flags are now returned in cmd->return_flags by KDBUS_CMD_NAME_ACQUIRE * struct kdbus_item_list has been dropped. The information stored in this struct was redundant since awhile already, as all commands report their returned slice size anyway.
2015-02-19bus: sync with kdbus.git (ABI break)David Herrmann
This syncs up the new KDBUS_CMD_CONN_INFO behavior: - attach-flags are passed in .attach_flags, instead of directly merged with the command flags.
2015-02-17bus: sync with kdbusDavid Herrmann
Pull in new kdbus changes, namely: - EOVERFLOW is replaces by KDBUS_RECV_RETURN_DROPPED_MSGS - ENOMSG is merged with EAGAIN for consistency

Just a simple variable rename, and a dropped flag that sd-bus didn't make use of.

2015-01-05sd-bus: sync kdbus.hDaniel Mack
Catch up with latest changes in kdbus.ko: * Signals can be sent as unicast now, hence they need to be marked as such with the KDBUS_MSG_SIGNAL in the message flags. * Follow ioctl number change for KDBUS_CMD_FREE
2014-12-20sd-bus: sync kdbus.h (ABI break)Daniel Mack
Sync kdbus.h with upstream changes: * Two optional cancellation points where added for synchronously blocking KDBUS_CMD_SEND commands: A sigmask to change the mask of accepted signals before the task is put to sleep, and a generic file descriptor that can be written to, in order to cancel the command. Both methods are currently unused. * The KDBUS_CMD_CANCEL ioctl was removed. sd-bus was never using that command, so there's no change needed. * Some kerneldoc fixes
2014-12-11bus: sync with kdbus.gitDavid Herrmann
Changes: * bloom parameters are returned in an offset via HELLO * FREE now takes items just like any other ioctl
2014-12-11bus: sync with kdbus.gitDavid Herrmann
Sync up with recent kdbus changed: * several ioctls gained .size and .items members (but still unused) * CMD_SEND gained its own ioctl structure * several members of kdbus_msg were dropped as they were only used during SEND, not during RECV etc. * CMD_RECV and CMD_SEND now share a kdbus_reply member which contains the offset and size of the returned message.
2014-12-09sd-bus: get rid of PID starttime conceptLennart Poettering
As kdbus no longer exports this, remove all traces from sd-bus too
2014-12-09bus: sync with kdbus-git (ABI break)David Herrmann
kdbus-git gained two new features: * memfd offsets: This allows to specify a 'start' offset in kdbus_memfd so you can send partial memfd hunks instead of always the full memfd * KDBUS_HELLO_UNPRIVILEGED: If passed during HELLO, the client will be treated as unprivileged.

2014-11-26bus: update kdbus.h (ABI break)David Herrmann
We changed creds to u32, so fix systemd sd-bus to acknowledge that.

2014-11-25kdbus: update header file to current upstream versionLennart Poettering
2014-11-25sd-bus: update to current kernel version, by splitting off the extended ↵Lennart Poettering
KDBUS_ITEM_PIDS structure from KDBUS_ITEM_CREDS Also: - adds support for euid, suid, fsuid, egid, sgid, fsgid fields. - makes augmentation of creds with data from /proc explicitly controllable to give apps better control over this, given that this is racy. - enables augmentation for kdbus connections (previously we only did it for dbus1). This is useful since with recent kdbus versions it is possible for clients to control the metadata they want to send. - changes sd_bus_query_sender_privilege() to take the euid of the client into consideration, if known - when we don't have permissions to read augmentation data from /proc, don't fail, just don't add the data in
2014-11-13sd-bus: sync with kdbus upstream (ABI break)Daniel Mack
kdbus has seen a larger update than expected lately, most notably with kdbusfs, a file system to expose the kdbus control files: * Each time a file system of this type is mounted, a new kdbus domain is created. * The layout inside each mount point is the same as before, except that domains are not hierarchically nested anymore. * Domains are therefore also unnamed now. * Unmounting a kdbusfs will automatically also detroy the associated domain. * Hence, the action of creating a kdbus domain is now as privileged as mounting a filesystem. * This way, we can get around creating dev nodes for everything, which is last but not least something that is not limited by 20-bit minor numbers. The kdbus specific bits in nspawn have all been dropped now, as nspawn can rely on the container OS to set up its own kdbus domain, simply by mounting a new instance. A new set of mounts has been added to mount things *after* the kernel modules have been loaded. For now, only kdbus is in this set, which is invoked with mount_setup_late().
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: 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
2014-10-27sd-bus: sync kdbus.h (ABI break)Daniel Mack
Some comment fixes and header cleanups in kdbus.h, and the task capability meta information has been factored out to its own struct.
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.
2014-10-21sd-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.
2014-10-20sd-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.
2014-10-08sd-bus: sync kdbus.h (ABI break)Daniel Mack
Sync kdbus.h once again. Two thing have changed: a) KDBUS_CMD_EP_* was renamed to KDBUS_CMD_ENDPOINT_* b) struct kdbus_cmd_hello and struct kdbus_cmd_make gained a 'features' bitfield (which is currently unused)
2014-10-06sd-bus: sync kdbus.h (ABI break)Daniel Mack
The KDBUS_CMD_FREE ioctl now uses a struct rather than a direct pointer to the offset to free. The KDBUS_CMD_MSG_CANCEL ioctl has also changes, but there's no user of it yet in systemd.
2014-10-02sd-bus: sync kdbus.h (ABI break!)Daniel Mack
struct kdbus_cmd_match got a flags field, which systemd currently makes no use of.
2014-10-02sd-bus: sync kdbus.h (ABI break)Daniel Mack
struct kdbus_cmd_conn_info takes a list of items now instead of a string. Fix the only user in SD of that ioctl.

2014-09-23sd-bus: sync kdbus.h (API break)Daniel Mack
Just a rename of two struct members to make the header file c++ compatible.
2014-09-22sd-bus: sync kdbus.h (API+ABI break)Daniel Mack
The kdbus logic name registry logic was changed to transport the actual name to acquire, release or report in a kdbus item. This brings the name API a little more in line with other calls, and allows for later augmentation. Follow that change on the systemd side.

Bring kdbus.h in sync with recent policy related changes. Most notably, KDBUS_MAKE_POLICY_OPEN is now gone. The rest doesn't matter for systemd at this point, as the policy functionality was not yet used.
