This reverts commit d4d00020d6ad855d65d31020fefa5003e1bb477f. The idea of
the commit is broken and needs to be reworked. We really cannot reduce
the bus-addresses to a single address. We always will have systemd with
native clients and legacy clients at the same time, so we also need both
addresses at the same time.
|
|
We use dashes in our bloom-tags. Make sure the newly introduced arg0has
tag uses the same style.
Note that the external dbus-tags don't use dashes, though. They are
defined in the spec and we need to keep compatibility there.
|
|
Previously, sd-bus inofficially already supported bus matches that
tested a string against an array of strings ("as"). This was done via an
enhanced way to interpret "arg0=" matches. This is problematic however,
since clients have no way to determine if their respective
implementation understood strv matches or not, thus allowing invalid
matches to be installed without a way to detect that.
This patch changes the logic to only allow such matches with a new
"arg0has=" syntax. This has the benefit that non-conforming
implementations will return a parse error and a client application may
thus efficiently detect support for the match type.
Matches of this type are useful for "udev"-like systems that "tag" objects
with a number of strings, and clients need to be able to match against
any of these "tags".
The name "has" takes inspiration from Python's ".has_key()" construct.

We should not fall back to dbus-1 and connect to the proxy when kdbus
returns an error that indicates that kdbus is running but just does not
accept new connections because of quota limits or something similar.
Using is_kdbus_available() in libsystemd/ requires it to move from
shared/ to libsystemd/.
Based on a patch from David Herrmann:

The kernel nowadays sends these along, and that's OK, hence don't even
debug log about it, but completely ignore it.
|
|
|
|
In bus_kernel_translate_message(), we print a DEBUG message on unknown
items. But right now, we also print this message for KDBUS_ITEM_TIMESTAMP
despite parsing it properly. Fix this!
|
|
When we get notifications from the kernel, we always turn them into
synthetic dbus1 messages. This means, we do *not* consume the kdbus
message, and as such have to free the offset.
Right now, the translation-helpers told the caller that they consumed the
message, which is wrong. Fix this by explicitly releasing all kernel
messages that are translated.

XDG refers to X Desktop Group, a former name for freedesktop.org.
This group is responsible for specifications like basedirs,
.desktop files and icon naming, but as far as I know, it has never
tried to redefine basename().
I think these references were meant to say XPG (X/Open Portability
Guide), a precursor of POSIX. POSIX is better-known and less easily
confused with XDG, and is how the basename(3) man page describes
the libgen.h version of basename().
The other version of basename() is glibc-specific and is described
in basename(3) as "the GNU version"; specifically mention that
version, to disambiguate.

use it anymore

Right now we always pass KDBUS_ITEM_ATTACH_FLAGS_RECV to
KDBUS_CMD_BUS_MAKE, effectively forcing every bus connection to do the
same during KDBUS_CMD_HELLO. This used to be a workaround to make sure all
metadata is always present. However, we refrained from that approach and
intend to make all metadata collection solely rely on /proc access
restrictions. Therefore, there is no need to force the send-flags mask on
newly created buses.

As perparation for future incompatible kdbus kernel API changes.

A number of fields do not apply to all processes, including: there a
processes without a controlling tty, without parent process, without
service, user services or session. To distuingish these cases from the
case where we simply don't have the data, always return ENXIO for them,
while returning ENODATA for the case where we really lack the
information.
Also update the credentials dumping code to show this properly. Fields
that are known but do not apply are now shown as "n/a".
Note that this also changes some of the calls in process-util.c and
cgroup-util.c to return ENXIO for these cases.
|
|
kdbus has been passing us the ppid file for a while, actually make use
of it.
|
|
|
|
Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.
|
|
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.
|
|
This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.
|
|
Pull in new kdbus changes, namely:
- EOVERFLOW is replaces by KDBUS_RECV_RETURN_DROPPED_MSGS
- ENOMSG is merged with EAGAIN for consistency

their entirety as gvariant objects""
This reverts commit 954871d8ba15911d014f76ed2c7a9492953cf39d.
|
|
Another slice logic rework in kdbus made KDBUS_ITEM_PAYLOAD_OFF items
relative to the message header again. Catch up with that in sd-bus.
|
|
Also, document in adjacent comments and in CODING_STYLE why we do that.

entirety as gvariant objects"
This breaks booting with kdbus.
This reverts commit b381de4197157748ed96e469fcc372c23f842ae1.

as gvariant objects
Previously, we only minimally altered the dbus1 framing for kdbus, and
while the header and its fields where compliant Gvariant objects, and so
was the body, the entire message together was not.
As result of discussions with Ryan Lortie this is now changed, so that
the messages in there entirely are fully compliant GVariants. This
follows the framing description described here:
https://wiki.gnome.org/Projects/GLib/GDBus/Version2
Note that this change changes the framing of *all* messages sent via
kdbus, this means you have to reboot your kdbus system, after compiling
and installing this new version.

There is no reason to provide our own attach_flags_mask. We can simply
rely on kdbus.attach_flags_mask= which is read by the kernel *and* kmod.
If it's set, we assume the user wants to override our setting, so we
simply skip setting it.
|
|
Just a simple variable rename, and a dropped flag that sd-bus didn't make
use of.
|
|
Make sure to append bloom-filters to all signal-messages, not only
broadcasts.
|
|
|
|
|
|
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
|

The kernel provides capabilities as a u32 array, sd-bus uses an u8 array.
This works fine on little-endian as both are encoded the same way.
However, this fails on big-endian if we do not perform sufficient
byte-swapping on each u32 entry.
This patch makes sd-bus use u32, too. We avoid changing any kernel
provided data so we can keep pointing into kdbus pool buffers which
contain u32 arrays.
|
|
The number of available caps can be read from
/proc/sys/kernel/cap_last_cap during runtime. Our helper cap_last_cap()
does that, so there's no reason to remember the size of any capability
cache. We can just pre-allocate arrays with a suitable size for all
available caps and reject any higher caps.
The kernel capability API uses u32 as base so make sure we do the same.
Note that this is specified by POSIX, so it's unlikely to change.

Drop spurious 'we'.

files from core
Stuff in src/shared or src/libsystemd should *never* include code from
src/core or any of the tools, so don't do that here either. It's not OK!
|
|
Kernel notifications carry a timestamp now, so make sure
bus_kernel_translate_message() doesn't complain when it stumbles across
them.
|
|
Make sure to set send-attach-flags on BUS_MAKE. These control which
information is revealed about the bus-owner.
|
|
Make sure we don't call into any bus_kernel_*() functions before
b->is_kernel is set to true. Hard-code the CMD_FREE just like the other
helpers do.
|
|
Changes:
* bloom parameters are returned in an offset via HELLO
* FREE now takes items just like any other ioctl
|
|
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.
|
|
kdbus is not available
|
|
As kdbus no longer exports this, remove all traces from sd-bus too
|
|
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.
|
|
Implement a recent change in the kdbus pool logic:
PAYLOAD_VEC_OFF items are now referencing offsets relative to the
connection's pool, not to the item itself. Follow this change in
sd-bus.
