tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

util-lib: split our string related calls from util.[ch] into its own file string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.

sd-bus: introduce new match type "arg0has=" for matching arrays of strings 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.

sd-bus: remove ucred parameter from bus_message_from_header() since we don't use it anymore

sd-bus, shared: fix includes Include <sys/socket.h> from util.h and bus-message.h in order to build errors like the ones below on kdbus enabled systems. ./src/shared/util.h:976:32: warning: its scope is only this definition or declaration, which is probably not what you want In file included from src/libsystemd/sd-bus/bus-kernel.c:37:0: ./src/shared/util.h:1081:28: warning: 'struct msghdr' declared inside parameter list void cmsg_close_all(struct msghdr *mh); ^ CC src/libsystemd/sd-bus/libsystemd_la-bus-creds.lo In file included from src/libsystemd/sd-bus/bus-creds.c:25:0: ./src/shared/util.h:976:32: warning: 'struct ucred' declared inside parameter list int getpeercred(int fd, struct ucred *ucred); ^

remove unused includes 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.

Revert "Revert "sd-bus: change serialization of kdbus messages to qualify in their entirety as gvariant objects"" This reverts commit 954871d8ba15911d014f76ed2c7a9492953cf39d.

Revert "sd-bus: change serialization of kdbus messages to qualify in their entirety as gvariant objects" This breaks booting with kdbus. This reverts commit b381de4197157748ed96e469fcc372c23f842ae1.

sd-bus: change serialization of kdbus messages to qualify in their entirety 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.

sd-bus: unify how we set the sender of synthetic messages

sd-bus: properly support passing memfds around with offset/size parameters

bus: sync with kdbus-git (ABI break) 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.

sd-bus: move packet header definition to bus-protocol.h

sd-bus: add support for matches against arrays of strings in messages

sd-bus: add sd_bus_message.verify_destination_id and .destination_ptr 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.

sd-bus: don't look for a 64bit value when we only have 32bit value on reply cookie hash table access This broke hashtable lookups for the message cookies on s390x, which is a 64bit BE machine where accessing 32bit values as 64bit and vice versa will explode. Also, while we are at it, be a bit more careful when dealing with the 64bit cookies we expose and the 32bit serial numbers dbus uses in its payload. Problem identified by Fridrich Strba.

bus: expose priority field of messages, in preparation for prioq support

bus: add API for querying the kdbus message sequence number

libsystemd: split up into subdirs We still only produce on .so, but let's keep the sources separate to make things a bit less messy.
