2015-08-27Revert "sd-bus: do not connect to dbus-1 socket when kdbus is available"David Herrmann
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.
2015-08-11 sd-bus: do not connect to dbus-1 socket when kdbus is availableKay Sievers
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: https://github.com/systemd/systemd/pull/886

busctl: make sure --address connects as bus-client
2015-07-31busctl: make sure --address connects as bus-clientDavid Herrmann
There is really no reason to use `busctl` to connect to legacy private bus endpoints. Fix this and make sure `busctl --address=unix:path=/foo` works!
2015-08-01busctl: fix assertion failure on --size optionNamhyung Kim
Using --size option triggers an assert failure below because parse_size() requires the second argument, base, being either 1000 or 1024. As it's for a packet size, it'd be better using IEC binary suffix (base 1024) IMHO. $ busctl --size 2048 Assertion 'base == 1000 || base == 1024' failed at src/basic/util.c:2222, function parse_size(). Aborting. Aborted (core dumped)
2015-08-01busctl: add missing description of --size optionNamhyung Kim
The size option was to specify maximum captured patch length but was missing its description in the command line help. Add it.
2015-08-01busctl: add and use strcmp_ptr()Namhyung Kim
In member_compare_func(), it compares interface, type and name of members. But as it can contain NULL pointer, it needs to check them before calling strcmp(). So make it as a separate strcmp_ptr function (named after streq_ptr) so that it can be used by others. Also let streq_ptr() to use it in order to make the code simpler.

sd-bus: introduce new sd_bus_flush_close_unref() call
2015-07-04busctl: flush stdout after dumping dataDavid Herrmann
Running `busctl monitor` currently buffers data for several seconds / kilobytes before writing stdout. This is highly confusing if you dump in a file, ^C busctl and then end up with a file with data of the last few _seconds_ missing. Fix this by explicitly flushing after each signal.
2015-07-03sd-bus: introduce new sd_bus_flush_close_unref() callLennart Poettering
sd_bus_flush_close_unref() is a call that simply combines sd_bus_flush() (which writes all unwritten messages out) + sd_bus_close() (which terminates the connection, releasing all unread messages) + sd_bus_unref() (which frees the connection). The combination of this call is used pretty frequently in systemd tools right before exiting, and should also be relevant for most external clients, and is hence useful to cover in a call of its own. Previously the combination of the three calls was already done in the _cleanup_bus_close_unref_ macro, but this was only available internally. Also see #327

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.
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.

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.

2014-12-23core: 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: 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().

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).
