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 out allocation calls into alloc-util.[ch]

src/basic: rename audit.[ch] → audit-util.[ch] and capability.[ch] → capability-util.[ch] The files are named too generically, so that they might conflict with the upstream project headers. Hence, let's add a "-util" suffix, to clarify that this are just our utility headers and not any official upstream headers.

util-lib: move more locale-related calls to locale-util.[ch]

util-lib: move more file I/O related calls into fileio.[ch]

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.

cgtop: underline table header Let's underline the header line of the table shown by cgtop, how it is customary for tables. In order to do this, let's introduce new ANSI underline macros, and clean up the existing ones as side effect.

tree-wide: port everything over to fflush_and_check() Some places invoked fflush() directly with their own manual error checking, let's unify all that by using fflush_and_check(). This also unifies the general error paths of fflush()+rename() file writers.

sd-bus,sd-login: add api for querying the slice within the the user systemd instance of a process units are organized in slice trees, not only for the system instance, but also for user systemd instances, expose this properly.

sd-bus: properly handle creds that are known but undefined for a process 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.

sd-bus: add controlling tty field to sd_creds object This is useful to print wall messages from logind with the right client tty. (to be added in a later patch)

sd-bus: expose ppid field kdbus has been passing us the ppid file for a while, actually make use of it.

shared: add terminal-util.[ch]

shared: add formats-util.h

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.

util: rework strappenda(), and rename it strjoina() After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.

bus-dump: fix two minor memory leaks

Assorted format fixes Types used for pids and uids in various interfaces are unpredictable. Too bad.

sd-bus: tell Coverity that it's OK not to care for return values in some cases

util: introduce our own gperf based capability list This way, we can ensure we have a more complete, up-to-date list of capabilities around, always.

sd-bus: get rid of PID starttime concept As kdbus no longer exports this, remove all traces from sd-bus too

treewide: more log_*_errno + return simplifications

treewide: no need to negate errno for log_*_errno() It corrrectly handles both positive and negative errno values.

treewide: auto-convert the simple cases to log_*_errno() As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().

sd-bus: add supplementary groups list to creds object

sd-bus: update to current kernel version, by splitting off the extended 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

bus: change creds dumping order to be more close to internal storage order

busctl: improve output of service creds

busctl: introduce busctl "get-property" command for reading and dumping object properties

sd-bus: rename "connection name" to "description" for the sd-bus API too kdbus recently renamed this concept, and so should we in what we expose in userspace.

busctl: add new "capture" verb to record bus messages in libpcap compatible files, for dissection with wireshark

Remove unnecessary casts in printfs No functional change expected :)

delta: draw arrows with draw_special_char() Let's unify generation of unicode chars at one place. Also, don't add an extra space into chars we print, except for the tree chars where this is really necessary.

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

busctl: include connection name in busctl output

bus: include connection name in credentials structure

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.
