-Known differences between dbus1 and kdbus:
-
-- NameAcquired/NameLost is gone entirely on kdbus backends if
- libsystemd is used. It is still added in by systemd-bus-proxyd
- for old dbus1 clients, and it is available if libsystemd is used
- against the classic dbus1 daemon. If you want to write compatible
- code with libsystem-bus you need to explicitly subscribe to
- NameOwnerChanged signals and just ignore NameAcquired/NameLost
-
-- Applications have to deal with spurious signals they didn't expect,
- due to the probabilistic bloom filters. They need to handle this
- anyway, given that any client can send anything to arbitrary clients
- anyway, even in dbus1, so not much changes.
-
-- clients of the system bus when kdbus is used must roll their own
- security. Only legacy dbus1 clients get the old XML policy enforced,
- which is implemented by systemd-bus-proxyd.
-
-- Serial numbers of synthesized messages are always (uint32_t) -1.
-
-- NameOwnerChanged is a synthetic message, generated locally and not
- by the driver. On dbus1 only the Disconnected message was
- synthesized like this.
-
-- There's no standard per-session bus anymore. Only a per-user bus.

-How we use GVariant for serializing D-Bus messages
---------------------------------------------------
-
-We stay close to the original dbus1 framing as possible, but make
-certain changes to adapt for GVariant. dbus1 has the following
-framing:
-
- 1. A fixed header of "yyyyuu"
- 2. Additional header fields of "a(yv)"
- 3. Padding with NUL bytes to pad up to next 8byte boundary
- 4. The body
-
-Note that the body is not padded at the end, the complete message
-hence might have a non-aligned size. Reading multiple messages at once
-will hence result in possibly unaligned messages in memory.
-
-The header consists of the following:
-
- y Endianness, 'l' or 'B'
- y Message Type
- y Flags
- y Protocol version, '1'
- u Length of the body, i.e. the length of part 4 above
- u 32bit Serial number
-
- = 12 bytes
-
-This header is then followed by the fields array, whose first value is
-a 32bit array size.
-
-When using GVariant we keep the basic structure in place, only
-slightly alter the header, and define protocol version '2'. The new
-header:
-
- y Endianness, 'l' or 'B'
- y Message Type
- y Flags
- y Protocol version, '2'
- u Reserved, must be 0
- t 64bit Cookie
-
- = 16 bytes
-
-This is then followed by the GVariant fields array ("a{tv}"), and
-finally the actual body as variant (v). Putting this altogether a
-packet on dbus2 hence qualifies as a fully compliant GVariant
-structure of (yyyyuta{tv}v).
-
-For details on gvariant, see:
-
-https://people.gnome.org/~desrt/gvariant-serialisation.pdf
-
-Regarding the framing of dbus2, also see:
-
-https://wiki.gnome.org/Projects/GLib/GDBus/Version2
-
-The first four bytes of the header are defined the same way for dbus1
-and dbus2. The first bytes contain the endianess field and the
-protocol version, so that the remainder of the message can be safely
-made sense of just by looking at the first 32bit.
-
-Note that the length of the body is no longer included in the header
-on dbus2! In fact, the message size must be known in advance, from the
-underlying transport in order to parse dbus2 messages, while it is
-directly included in dbus1 message headers. This change of semantics
-is an effect of GVariant's basic design.
-
-The serial number has been renamed cookie and has been extended from
-32bit to 64bit. It is recommended to avoid the higher 32bit of the
-cookie field though, to simplify compatibility with dbus1 peers. Note
-that not only the cookie/serial field in the fixed header, but also
-the reply_cookie/reply_serial additional header field has been
-increased from 32bit to 64bit, too!
-
-The header field identifiers have been extended from 8bit to
-64bit. This has been done to simplify things (as kdbus otherwise uses
-exclusively 64bit types, unless there is a strong reason not to), and
-has no effect on the serialization size, as due to alignment for each
-8bit header field identifier 56 bits of padding had to be added.
-
-Note that the header size changed, due to these changes. However,
-consider that on dbus1 the beginning of the fields array contains the
-32bit array size (since that is how arrays are encoded on dbus1),
-thus, if one considers that size part of the header, instead of the
-array, the size of the header on dbus1 and dbus2 stays identical, at
-16 bytes.
-
- 0 4 8 12 16
- Common: | E | T | F | V | ...
-
- dbus1: | (as above) | Body Length | Serial | Fields Length | Fields array ...
-
- gvariant: | (as above) | Reserved | Cookie | Fields array ...
-
-And that's already it.
-
-Note: to simplify parsing, valid kdbus/dbus2 messages must include the
-entire fixed header and additional header fields in a single non-memfd
-message part. Also, the signature string of the body variant all the
-way to the end of the message must be in a single non-memfd part
-too. The parts for this extended header and footer can be the same
-one, and can also continue any amount of additional body bytes.
-
-Note: on kdbus only native endian messages marshalled in gvariant may
- be sent. If a client receives a message in non-native endianness
- or in dbus1 marshalling it shall ignore the message.
-
-Note: The GVariant "MAYBE" type is not supported, so that messages can
- be fully converted forth and back between dbus1 and gvariant
- representations.

-A few hints on supporting kdbus as backend in your favorite D-Bus library.
-
-~~~
-
-Before you read this, have a look at the DIFFERENCES and
-GVARIANT_SERIALIZATION texts you find in the same directory where you
-found this.
-
-We invite you to port your favorite D-Bus protocol implementation
-over to kdbus. However, there are a couple of complexities
-involved. On kdbus we only speak GVariant marshaling, kdbus clients
-ignore traffic in dbus1 marshaling. Thus, you need to add a second,
-GVariant compatible marshaler to your library first.
-
-After you have done that: here's the basic principle how kdbus works:
-
-You connect to a bus by opening its bus node in /sys/fs/kdbus/. All
-buses have a device node there, it starts with a numeric UID of the
-owner of the bus, followed by a dash and a string identifying the
-bus. The system bus is thus called /sys/fs/kdbus/0-system, and for user
-buses the device node is /sys/fs/kdbus/1000-user (if 1000 is your user
-id).
-
-(Before we proceed, please always keep a copy of libsystemd next
-to you, ultimately that's where the details are, this document simply
-is a rough overview to help you grok things.)
-
-CONNECTING
-
-To connect to a bus, simply open() its device node and issue the
-KDBUS_CMD_HELLO call. That's it. Now you are connected. Do not send
-Hello messages or so (as you would on dbus1), that does not exist for
-kdbus.
-
-The structure you pass to the ioctl will contain a couple of
-parameters that you need to know, to operate on the bus.
-
-There are two flags fields, one indicating features of the kdbus
-kernel side ("conn_flags"), the other one ("bus_flags") indicating
-features of the bus owner (i.e. systemd). Both flags fields are 64bit
-in width.
-
-When calling into the ioctl, you need to place your own supported
-feature bits into these fields. This tells the kernel about the
-features you support. When the ioctl returns, it will contain the
-features the kernel supports.
-
-If any of the higher 32bit are set on the two flags fields and your
-client does not know what they mean, it must disconnect. The upper
-32bit are used to indicate "incompatible" feature additions on the bus
-system, the lower 32bit indicate "compatible" feature additions. A
-client that does not support a "compatible" feature addition can go on
-communicating with the bus, however a client that does not support an
-"incompatible" feature must not proceed with the connection. When a
-client encountes such an "incompatible" feature it should immediately
-try the next bus address configured in the bus address string.
-
-The hello structure also contains another flags field "attach_flags"
-which indicates metadata that is optionally attached to all incoming
-messages. You probably want to set KDBUS_ATTACH_NAMES unconditionally
-in it. This has the effect that all well-known names of a sender are
-attached to all incoming messages. You need this information to
-implement matches that match on a message sender name correctly. Of
-course, you should only request the attachment of as little metadata
-fields as you need.
-
-The kernel will return in the "id" field your unique id. This is a
-simple numeric value. For compatibility with classic dbus1 simply
-format this as string and prefix ":1.".
-
-The kernel will also return the bloom filter size and bloom filter
-hash function number used for the signal broadcast bloom filter (see
-below).
-
-The kernel will also return the bus ID of the bus in a 128bit field.
-
-The pool size field specifies the size of the memory mapped buffer.
-After the calling the hello ioctl, you should memory map the kdbus
-fd. In this memory mapped region, the kernel will place all your incoming
-messages.
-
-SENDING MESSAGES
-
-Use the MSG_SEND ioctl to send a message to another peer. The ioctl
-takes a structure that contains a variety of fields:
-
-The flags field corresponds closely to the old dbus1 message header
-flags field, though the DONT_EXPECT_REPLY field got inverted into
-EXPECT_REPLY.
-
-The dst_id/src_id field contains the unique id of the destination and
-the sender. The sender field is overridden by the kernel usually, hence
-you shouldn't fill it in. The destination field can also take the
-special value KDBUS_DST_ID_BROADCAST for broadcast messages. For
-messages intended to a well-known name set the field to
-KDBUS_DST_ID_NAME, and attach the name in a special "items" entry to
-the message (see below).
-
-The payload field indicates the payload. For all dbus traffic it
-should carry the value 0x4442757344427573ULL. (Which encodes
-'DBusDBus').
-
-The cookie field corresponds with the "serial" field of classic
-dbus1. We simply renamed it here (and extended it to 64bit) since we
-didn't want to imply the monotonicity of the assignment the way the
-word "serial" indicates it.
-
-When sending a message that expects a reply, you need to set the
-EXPECT_REPLY flag in the message flag field. In this case you should
-also fill out the "timeout_ns" value which indicates the timeout in
-nsec for this call. If the peer does not respond in this time you will
-get a notification of a timeout. Note that this is also used for
-security purposes: a single reply messages is only allowed through the
-bus as long as the timeout has not ended. With this timeout value you
-hence "open a time window" in which the peer might respond to your
-request and the policy allows the response to go through.
-
-When sending a message that is a reply, you need to fill in the
-cookie_reply field, which is similar to the reply_serial field of
-dbus1. Note that a message cannot have EXPECT_REPLY and a reply_serial
-at the same time!
-
-This pretty much explains the ioctl header. The actual payload of the
-data is now referenced in additional items that are attached to this
-ioctl header structure at the end. When sending a message, you attach
-items of the type PAYLOAD_VEC, PAYLOAD_MEMFD, FDS, BLOOM_FILTER,
-DST_NAME to it:
-
- KDBUS_ITEM_PAYLOAD_VEC: contains a pointer + length pair for
- referencing arbitrary user memory. This is how you reference most
- of your data. It's a lot like the good old iovec structure of glibc.
-
- KDBUS_ITEM_PAYLOAD_MEMFD: for large data blocks it is preferable
- to send prepared "memfds" (see below) over. This item contains an
- fd for a memfd plus a size.
-
- KDBUS_ITEM_FDS: for sending over fds attach an item of this type with
- an array of fds.
-
- KDBUS_ITEM_BLOOM_FILTER: the calculated bloom filter of this message,
- only for undirected (broadcast) message.
-
- KDBUS_ITEM_DST_NAME: for messages that are directed to a well-known
- name (instead of a unique name), this item contains the well-known
- name field.
-
-A single message may consists of no, one or more payload items of type
-PAYLOAD_VEC or PAYLOAD_MEMFD. D-Bus protocol implementations should
-treat them as a single block that just happens to be split up into
-multiple items. Some restrictions apply however:
-
- The message header in its entirety must be contained in a single
- PAYLOAD_VEC item.
-
- You may only split your message up right in front of each GVariant
- contained in the payload, as well is immediately before framing of a
- Gvariant, as well after as any padding bytes if there are any. The
- padding bytes must be wholly contained in the preceding
- PAYLOAD_VEC/PAYLOAD_MEMFD item. You may not split up basic types
- nor arrays of fixed types. The latter is necessary to allow APIs
- to return direct pointers to linear arrays of numeric
- values. Examples: The basic types "u", "s", "t" have to be in the
- same payload item. The array of fixed types "ay", "ai" have to be
- fully in contained in the same payload item. For an array "as" or
- "a(si)" the only restriction however is to keep each string
- individually in an uninterrupted item, to keep the framing of each
- element and the array in a single uninterrupted item, however the
- various strings might end up in different items.
-
-Note again, that splitting up messages into separate items is up to the
-implementation. Also note that the kdbus kernel side might merge
-separate items if it deems this to be useful. However, the order in
-which items are contained in the message is left untouched.
-
-PAYLOAD_MEMFD items allow zero-copy data transfer (see below regarding
-the memfd concept). Note however that the overhead of mapping these
-makes them relatively expensive, and only worth the trouble for memory
-blocks > 512K (this value appears to be quite universal across
-architectures, as we tested). Thus we recommend sending PAYLOAD_VEC
-items over for small messages and restore to PAYLOAD_MEMFD items for
-messages > 512K. Since while building up the message you might not
-know yet whether it will grow beyond this boundary a good approach is
-to simply build the message unconditionally in a memfd
-object. However, when the message is sealed to be sent away check for
-the size limit. If the size of the message is < 512K, then simply send
-the data as PAYLOAD_VEC and reuse the memfd. If it is >= 512K, seal
-the memfd and send it as PAYLOAD_MEMFD, and allocate a new memfd for
-the next message.
-
-RECEIVING MESSAGES
-
-Use the MSG_RECV ioctl to read a message from kdbus. This will return
-an offset into the pool memory map, relative to its beginning.
-
-The received message structure more or less follows the structure of
-the message originally sent. However, certain changes have been
-made. In the header the src_id field will be filled in.
-
-The payload items might have gotten merged and PAYLOAD_VEC items are
-not used. Instead, you will only find PAYLOAD_OFF and PAYLOAD_MEMFD
-items. The former contain an offset and size into your memory mapped
-pool where you find the payload.
-
-If during the HELLO ioctl you asked for getting metadata attached to
-your message, you will find additional KDBUS_ITEM_CREDS,
-KDBUS_ITEM_PID_COMM, KDBUS_ITEM_TID_COMM, KDBUS_ITEM_TIMESTAMP,
-KDBUS_ITEM_EXE, KDBUS_ITEM_CMDLINE, KDBUS_ITEM_CGROUP,
-KDBUS_ITEM_CAPS, KDBUS_ITEM_SECLABEL, KDBUS_ITEM_AUDIT items that
-contain this metadata. This metadata will be gathered from the sender
-at the point in time it sends the message. This information is
-uncached, and since it is appended by the kernel, trustable. The
-KDBUS_ITEM_SECLABEL item usually contains the SELinux security label,
-if it is used.
-
-After processing the message you need to call the KDBUS_CMD_FREE
-ioctl, which releases the message from the pool, and allows the kernel
-to store another message there. Note that the memory used by the pool
-is ordinary anonymous, swappable memory that is backed by tmpfs. Hence
-there is no need to copy the message out of it quickly, instead you
-can just leave it there as long as you need it and release it via the
-FREE ioctl only after that's done.
-
-BLOOM FILTERS
-
-The kernel does not understand dbus marshaling, it will not look into
-the message payload. To allow clients to subscribe to specific subsets
-of the broadcast matches we employ bloom filters.
-
-When broadcasting messages, a bloom filter needs to be attached to the
-message in a KDBUS_ITEM_BLOOM item (and only for broadcasting
-messages!). If you don't know what bloom filters are, read up now on
-Wikipedia. In short: they are a very efficient way how to
-probabilistically check whether a certain word is contained in a
-vocabulary. It knows no false negatives, but it does know false
-positives.
-
-The parameters for the bloom filters that need to be included in
-broadcast message is communicated to userspace as part of the hello
-response structure (see above). By default it has the parameters m=512
-(bits in the filter), k=8 (nr of hash functions). Note however, that
-this is subject to change in later versions, and userspace
-implementations must be capable of handling m values between at least
-m=8 and m=2^32, and k values between at least k=1 and k=32. The
-underlying hash function is SipHash-2-4. It is used with a number of
-constant (yet originally randomly generated) 128bit hash keys, more
-specifically:
-
- b9,66,0b,f0,46,70,47,c1,88,75,c4,9c,54,b9,bd,15,
- aa,a1,54,a2,e0,71,4b,39,bf,e1,dd,2e,9f,c5,4a,3b,
- 63,fd,ae,be,cd,82,48,12,a1,6e,41,26,cb,fa,a0,c8,
- 23,be,45,29,32,d2,46,2d,82,03,52,28,fe,37,17,f5,
- 56,3b,bf,ee,5a,4f,43,39,af,aa,94,08,df,f0,fc,10,
- 31,80,c8,73,c7,ea,46,d3,aa,25,75,0f,9e,4c,09,29,
- 7d,f7,18,4b,7b,a4,44,d5,85,3c,06,e0,65,53,96,6d,
- f2,77,e9,6f,93,b5,4e,71,9a,0c,34,88,39,25,bf,35
-
-When calculating the first bit index into the bloom filter, the
-SipHash-2-4 hash value is calculated for the input data and the first
-16 bytes of the array above as hash key. Of the resulting 8 bytes of
-output, as many full bytes are taken for the bit index as necessary,
-starting from the output's first byte. For the second bit index the
-same hash value is used, continuing with the next unused output byte,
-and so on. Each time the bytes returned by the hash function are
-depleted it is recalculated with the next 16 byte hash key from the
-array above and the same input data.
-
-For each message to send across the bus we populate the bloom filter
-with all possible matchable strings. If a client then wants to
-subscribe to messages of this type, it simply tells the kernel to test
-its own calculated bit mask against the bloom filter of each message.
-
-More specifically, the following strings are added to the bloom filter
-of each message that is broadcasted:
-
- The string "interface:" suffixed by the interface name
-
- The string "member:" suffixed by the member name
-
- The string "path:" suffixed by the path name
-
- The string "path-slash-prefix:" suffixed with the path name, and
- also all prefixes of the path name (cut off at "/"), also prefixed
- with "path-slash-prefix".
-
- The string "message-type:" suffixed with the strings "signal",
- "method_call", "error" or "method_return" for the respective message
- type of the message.
-
- If the first argument of the message is a string, "arg0:" suffixed
- with the first argument.
-
- If the first argument of the message is a string, "arg0-dot-prefix"
- suffixed with the first argument, and also all prefixes of the
- argument (cut off at "."), also prefixed with "arg0-dot-prefix".
-
- If the first argument of the message is a string,
- "arg0-slash-prefix" suffixed with the first argument, and also all
- prefixes of the argument (cut off at "/"), also prefixed with
- "arg0-slash-prefix".
-
- Similar for all further arguments that are strings up to 63, for the
- arguments and their "dot" and "slash" prefixes. On the first
- argument that is not a string, addition to the bloom filter should be
- stopped however.
-
-(Note that the bloom filter does not contain sender nor receiver
-names!)
-
-When a client wants to subscribe to messages matching a certain
-expression, it should calculate the bloom mask following the same
-algorithm. The kernel will then simply test the mask against the
-attached bloom filters.
-
-Note that bloom filters are probabilistic, which means that clients
-might get messages they did not expect. Your bus protocol
-implementation must be capable of dealing with these unexpected
-messages (which it needs to anyway, given that transfers are
-relatively unrestricted on kdbus and people can send you all kinds of
-non-sense).
-
-If a client connects to a bus whose bloom filter metrics (i.e. filter
-size and number of hash functions) are outside of the range the client
-supports it must immediately disconnect and continue connection with
-the next bus address of the bus connection string.
-
-INSTALLING MATCHES
-
-To install matches for broadcast messages, use the KDBUS_CMD_ADD_MATCH
-ioctl. It takes a structure that contains an encoded match expression,
-and that is followed by one or more items, which are combined in an
-AND way. (Meaning: a message is matched exactly when all items
-attached to the original ioctl struct match).
-
-To match against other user messages add a KDBUS_ITEM_BLOOM item in
-the match (see above). Note that the bloom filter does not include
-matches to the sender names. To additionally check against sender
-names, use the KDBUS_ITEM_ID (for unique id matches) and
-KDBUS_ITEM_NAME (for well-known name matches) item types.
-
-To match against kernel generated messages (see below) you should add
-items of the same type as the kernel messages include,
-i.e. KDBUS_ITEM_NAME_ADD, KDBUS_ITEM_NAME_REMOVE,
-KDBUS_ITEM_NAME_CHANGE, KDBUS_ITEM_ID_ADD, KDBUS_ITEM_ID_REMOVE and
-fill them out. Note however, that you have some wildcards in this
-case, for example the .id field of KDBUS_ITEM_ID_ADD/KDBUS_ITEM_ID_REMOVE
-structures may be set to 0 to match against any id addition/removal.
-
-Note that dbus match strings do no map 1:1 to these ioctl() calls. In
-many cases (where the match string is "underspecified") you might need
-to issue up to six different ioctl() calls for the same match. For
-example, the empty match (which matches against all messages), would
-translate into one KDBUS_ITEM_BLOOM ioctl, one KDBUS_ITEM_NAME_ADD,
-one KDBUS_ITEM_NAME_CHANGE, one KDBUS_ITEM_NAME_REMOVE, one
-KDBUS_ITEM_ID_ADD and one KDBUS_ITEM_ID_REMOVE.
-
-When creating a match, you may attach a "cookie" value to them, which
-is used for deleting this match again. The cookie can be selected freely
-by the client. When issuing KDBUS_CMD_REMOVE_MATCH, simply pass the
-same cookie as before and all matches matching the same "cookie" value
-will be removed. This is particularly handy for the case where multiple
-ioctl()s are added for a single match strings.
-
-MEMFDS
-
-memfds may be sent across kdbus via KDBUS_ITEM_PAYLOAD_MEMFD items
-attached to messages. If this is done, the data included in the memfd
-is considered part of the payload stream of a message, and are treated
-the same way as KDBUS_ITEM_PAYLOAD_VEC by the receiving side. It is
-possible to interleave KDBUS_ITEM_PAYLOAD_MEMFD and
-KDBUS_ITEM_PAYLOAD_VEC items freely, by the reader they will be
-considered a single stream of bytes in the order these items appear in
-the message, that just happens to be split up at various places
-(regarding rules how they may be split up, see above). The kernel will
-refuse taking KDBUS_ITEM_PAYLOAD_MEMFD items that refer to memfds that
-are not sealed.
-
-Note that sealed memfds may be unsealed again if they are not mapped
-you have the only fd reference to them.
-
-Alternatively to sending memfds as KDBUS_ITEM_PAYLOAD_MEMFD items
-(where they are just a part of the payload stream of a message) you can
-also simply attach any memfd to a message using
-KDBUS_ITEM_PAYLOAD_FDS. In this case, the memfd contents is not
-considered part of the payload stream of the message, but simply fds
-like any other, that happen to be attached to the message.
-
-MESSAGES FROM THE KERNEL
-
-A couple of messages previously generated by the dbus1 bus driver are
-now generated by the kernel. Since the kernel does not understand the
-payload marshaling, they are generated by the kernel in a different
-format. This is indicated with the "payload type" field of the
-messages set to 0. Library implementations should take these messages
-and synthesize traditional driver messages for them on reception.
-
-More specifically:
-
- Instead of the NameOwnerChanged, NameLost, NameAcquired signals
- there are kernel messages containing KDBUS_ITEM_NAME_ADD,
- KDBUS_ITEM_NAME_REMOVE, KDBUS_ITEM_NAME_CHANGE, KDBUS_ITEM_ID_ADD,
- KDBUS_ITEM_ID_REMOVE items are generated (each message will contain
- exactly one of these items). Note that in libsystemd we have
- obsoleted NameLost/NameAcquired messages, since they are entirely
- redundant to NameOwnerChanged. This library will hence only
- synthesize NameOwnerChanged messages from these kernel messages,
- and never generate NameLost/NameAcquired. If your library needs to
- stay compatible to the old dbus1 userspace, you possibly might need
- to synthesize both a NameOwnerChanged and NameLost/NameAcquired
- message from the same kernel message.
-
- When a method call times out, a KDBUS_ITEM_REPLY_TIMEOUT message is
- generated. This should be synthesized into a method error reply
- message to the original call.
-
- When a method call fails because the peer terminated the connection
- before responding, a KDBUS_ITEM_REPLY_DEAD message is
- generated. Similarly, it should be synthesized into a method error
- reply message.
-
-For synthesized messages we recommend setting the cookie field to
-(uint32_t) -1 (and not (uint64_t) -1!), so that the cookie is not 0
-(which the dbus1 spec does not allow), but clearly recognizable as
-synthetic.
-
-Note that the KDBUS_ITEM_NAME_XYZ messages will actually inform you
-about all kinds of names, including activatable ones. Classic dbus1
-NameOwnerChanged messages OTOH are only generated when a name is
-really acquired on the bus and not just simply activatable. This means
-you must explicitly check for the case where an activatable name
-becomes acquired or an acquired name is lost and returns to be
-activatable.
-
-NAME REGISTRY
-
-To acquire names on the bus, use the KDBUS_CMD_NAME_ACQUIRE ioctl(). It
-takes a flags field similar to dbus1's RequestName() bus driver call,
-however the NO_QUEUE flag got inverted into a QUEUE flag instead.
-
-To release a previously acquired name use the KDBUS_CMD_NAME_RELEASE
-ioctl().
-
-To list acquired names use the KDBUS_CMD_CONN_INFO ioctl. It may be
-used to list unique names, well known names as well as activatable
-names and clients currently queuing for ownership of a well-known
-name. The ioctl will return an offset into the memory pool. After
-reading all the data you need, you need to release this via the
-KDBUS_CMD_FREE ioctl(), similar how you release a received message.
-
-CREDENTIALS
-
-kdbus can optionally attach various kinds of metadata about the sender at
-the point of time of sending ("credentials") to messages, on request
-of the receiver. This is both supported on directed and undirected
-(broadcast) messages. The metadata to attach is selected at time of
-the HELLO ioctl of the receiver via a flags field (see above). Note
-that clients must be able to handle that messages contain more
-metadata than they asked for themselves, to simplify implementation of
-broadcasting in the kernel. The receiver should not rely on this data
-to be around though, even though it will be correct if it happens to
-be attached. In order to avoid programming errors in applications, we
-recommend though not passing this data on to clients that did not
-explicitly ask for it.
-
-Credentials may also be queried for a well-known or unique name. Use
-the KDBUS_CMD_CONN_INFO for this. It will return an offset to the pool
-area again, which will contain the same credential items as messages
-have attached. Note that when issuing the ioctl, you can select a
-different set of credentials to gather, than what was originally requested
-for being attached to incoming messages.
-
-Credentials are always specific to the sender's domain that was
-current at the time of sending, and of the process that opened the
-bus connection at the time of opening it. Note that this latter data
-is cached!
-
-POLICY
-
-The kernel enforces only very limited policy on names. It will not do
-access filtering by userspace payload, and thus not by interface or
-method name.
-
-This ultimately means that most fine-grained policy enforcement needs
-to be done by the receiving process. We recommend using PolicyKit for
-any more complex checks. However, libraries should make simple static
-policy decisions regarding privileged/unprivileged method calls
-easy. We recommend doing this by enabling KDBUS_ATTACH_CAPS and
-KDBUS_ATTACH_CREDS for incoming messages, and then discerning client
-access by some capability, or if sender and receiver UIDs match.
-
-BUS ADDRESSES
-
-When connecting to kdbus use the "kernel:" protocol prefix in DBus
-address strings. The device node path is encoded in its "path="
-parameter.
-
-Client libraries should use the following connection string when
-connecting to the system bus:
-
- kernel:path=/sys/fs/kdbus/0-system/bus;unix:path=/var/run/dbus/system_bus_socket
-
-This will ensure that kdbus is preferred over the legacy AF_UNIX
-socket, but compatibility is kept. For the user bus use:
-
- kernel:path=/sys/fs/kdbus/$UID-user/bus;unix:path=$XDG_RUNTIME_DIR/bus
-
-With $UID replaced by the callers numer user ID, and $XDG_RUNTIME_DIR
-following the XDG basedir spec.
-
-Of course the $DBUS_SYSTEM_BUS_ADDRESS and $DBUS_SESSION_BUS_ADDRESS
-variables should still take precedence.
-
-DBUS SERVICE FILES
-
-Activatable services for kdbus may not use classic dbus1 service
-activation files. Instead, programs should drop in native systemd
-.service and .busname unit files, so that they are treated uniformly
-with other types of units and activation of the system.
-
-Note that this results in a major difference to classic dbus1:
-activatable bus names can be established at any time in the boot process.
-This is unlike dbus1 where activatable names are unconditionally available
-as long as dbus-daemon is running. Being able to control when
-activatable names are established is essential to allow usage of kdbus
-during early boot and in initrds, without the risk of triggering
-services too early.
-
-DISCLAIMER
-
-This all is so far just the status quo. We are putting this together, because
-we are quite confident that further API changes will be smaller, but
-to make this very clear: this is all subject to change, still!
-
-We invite you to port over your favorite dbus library to this new
-scheme, but please be prepared to make minor changes when we still
-change these interfaces!
