2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
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.
2015-01-18bus: use EUID over UID and fix unix-credsDavid Herrmann
Whenever a process performs an action on an object, the kernel uses the EUID of the process to do permission checks and to apply on any newly created objects. The UID of a process is only used if someone *ELSE* acts on the process. That is, the UID of a process defines who owns the process, the EUID defines what privileges are used by this process when performing an action. Process limits, on the other hand, are always applied to the real UID, not the effective UID. This is, because a process has a user object linked, which always corresponds to its UID. A process never has a user object linked for its EUID. Thus, accounting (and limits) is always done on the real UID. This commit fixes all sd-bus users to use the EUID when performing privilege checks and alike. Furthermore, it fixes unix-creds to be parsed as EUID, not UID (as the kernel always takes the EUID on UDS). Anyone using UID (eg., to do user-accounting) has to fall back to the EUID as UDS does not transmit the UID.
2015-01-07busctl: exit cleanly when the bus connection is severedLennart Poettering
2014-12-24sd-bus: rename sd_bus_open_system_container() to sd_bus_open_system_machine()Lennart Poettering
Pretty much everywhere else we use the generic term "machine" when referring to containers in API, so let's do though in sd-bus too. In particular, since the concept of a "container" exists in sd-bus too, but as part of the marshalling system.
2014-12-23busctl: when introspecting objects, optionally limit output by interface nameLennart Poettering
2014-12-23core: rearrange code so that libsystemd/sd-bus/ does not include header ↵Lennart Poettering
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!
2014-12-02busctl: fix 'command line' style output of propertiesLennart Poettering
2014-11-28sd-bus: add new sd_bus_get_address() for querying the current bus addressLennart Poettering
Also, update "busctl" to show this in its output.
2014-11-28sd-bus: rename sd_bus_get_owner_id() → sd_bus_get_bus_id()Lennart Poettering
The ID returned really doesn't identify the owner, but the bus instance, hence fix this misnaming. Also, update "busctl status" to show the ID in its output.
2014-11-28treewide: more log_*_errno + return simplificationsMichal Schmidt
2014-11-28sd-bus: add new call sd_bus_get_scope() for querying whether one is ↵Lennart Poettering
connected to a system or a user bus
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
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().
2014-11-26sd-bus: add suppot for renegotiating message credential attach flagsLennart Poettering
2014-11-25busctl: if no parameter is specified for "busctl status" show credentials of ↵Lennart Poettering
bus owner
2014-11-25busctl: add new --augment-creds= switch for controlling whether shown ↵Lennart Poettering
credential data shall be augment with data from /proc
2014-11-25busctl: improve readability a bitLennart Poettering
2014-11-21busctl: add --timeout= option to specify method call timeoutLennart Poettering
2014-11-21busctl: add options to control message header flags when invoking methodsLennart Poettering
2014-11-21busctl: show property values in "introspect" output, add "set-property" ↵Lennart Poettering
command, and support both a terse and a verbose output format
2014-11-21busctl: when --address is specified do not assume we connect to a full busLennart Poettering
2014-11-21busctl: use canned error message on parse failureLennart Poettering
2014-11-20busctl: pass error output to stdout (rather than stderr) when generate tree ↵Lennart Poettering
for all objects This is a ton more useful when some services fail, since we continue crawling then and output everything to a pager.
2014-11-20busctl: improve output of service credsLennart Poettering
2014-11-20busctl: add new "introspect" verb for introspecting objectsLennart Poettering
2014-11-20busctl: split out introspection parser from tree logic so that we can reuse ↵Lennart Poettering
it for a future "busctl introspect" command
2014-11-14busctl: introduce busctl "get-property" command for reading and dumping ↵Lennart Poettering
object properties
2014-11-14busctl: various tweaks to "busctl tree" outputLennart Poettering
2014-11-14busctl: add new "call" command to invoke methods on a serviceLennart Poettering
2014-11-10busctl: add "tree" command to explore object treesLennart Poettering
2014-11-04sd-bus: rename "connection name" to "description" for the sd-bus API tooLennart Poettering
kdbus recently renamed this concept, and so should we in what we expose in userspace.
2014-10-30busctl: add new "capture" verb to record bus messages in libpcap compatible ↵Lennart Poettering
files, for dissection with wireshark
2014-10-22sd-bus: rename sd_bus_get_owner_uid(), sd_bus_get_owner_machine_id() and ↵Daniel Mack
sd_bus_get_peer_creds() Clean up the function namespace by renaming the following: sd_bus_get_owner_uid() → sd_bus_get_name_creds_uid() sd_bus_get_owner_machine_id() → sd_bus_get_name_machine_id() sd_bus_get_peer_creds() → sd_bus_get_owner_creds()
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.
2014-08-04bus: always explicitly close bus from main programsLennart Poettering
Since b5eca3a2059f9399d1dc52cbcf9698674c4b1cf0 we don't attempt to GC busses anymore when unsent messages remain that keep their reference, when they otherwise are not referenced anymore. This means that if we explicitly want connections to go away, we need to close them. With this change we will no do so explicitly wherver we connect to the bus from a main program (and thus know when the bus connection should go away), or when we create a private bus connection, that really should go away after our use. This fixes connection leaks in the NSS and PAM modules.
2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.
2014-05-15sd-bus: introduce sd_bus_slot objects encapsulating callbacks or vtables ↵Lennart Poettering
attached to a bus connection This makes callback behaviour more like sd-event or sd-resolve, and creates proper object for unregistering callbacks. Taking the refernce to the slot is optional. If not taken life time of the slot will be bound to the underlying bus object (or in the case of an async call until the reply has been recieved).
2014-03-19busctl: when monitoring the bus, enable all credentialsLennart Poettering
2014-03-19sd-bus: add proper monitoring APILennart Poettering
2014-02-20api: in constructor function calls, always put the returned object pointer ↵Lennart Poettering
first (or second) Previously the returned object of constructor functions where sometimes returned as last, sometimes as first and sometimes as second parameter. Let's clean this up a bit. Here are the new rules: 1. The object the new object is derived from is put first, if there is any 2. The object we are creating will be returned in the next arguments 3. This is followed by any additional arguments Rationale: For functions that operate on an object we always put that object first. Constructors should probably not be too different in this regard. Also, if the additional parameters might want to use varargs which suggests to put them last. Note that this new scheme only applies to constructor functions, not to all other functions. We do give a lot of freedom for those. Note that this commit only changes the order of the new functions we added, for old ones we accept the wrong order and leave it like that.

2014-01-22busctl: include connection name in busctl outputLennart Poettering
2014-01-21libsystemd: split up into subdirsTom Gundersen
We still only produce on .so, but let's keep the sources separate to make things a bit less messy.
