2013-12-13event: when unreffing an event source from its own handler, detach fd from epollLennart Poettering
The pattern of unreffing an IO event source and then closing its fd is frequently seen in even source callbacks. Previously this likely resultet in us removing the fd from the epoll after it was closed which is problematic, since while we were dispatching we always kept an extra reference to event source objects because we might still need it later.
2013-12-13event: rework sd-event exit logicLennart Poettering
With this change a failing event source handler will not cause the entire event loop to fail. Instead, we just disable the specific event source, log a message at debug level and go on. This also introduces a new concept of "exit code" which can be stored in the event loop and is returned by sd_event_loop(). We also rename "quit" to "exit" everywhere else. Altogether this should make things more robus and keep errors local while still providing a way to return event loop errors in a clear way.

2013-12-11journal: add ability to browse journals of running OS containersLennart Poettering
This adds the new library call sd_journal_open_container() and a new "-M" switch to journalctl. Particular care is taken that journalctl's "-b" switch resolves to the current boot ID of the container, not the host.
2013-12-11journald: port to sd-event and enable watchdog supportLennart Poettering
2013-12-11event: hook up sd-event with the service watchdog logicLennart Poettering
Adds a new call sd_event_set_watchdog() that can be used to hook up the event loop with the watchdog supervision logic of systemd. If enabled and $WATCHDOG_USEC is set the event loop will ping the invoking systemd daemon right after coming back from epoll_wait() but not more often than $WATCHDOG_USEC/4. The epoll_wait() will sleep no longer than $WATCHDOG_USEC/4*3, to make sure the service manager is called in time. This means that setting WatchdogSec= in a .service file and calling sd_event_set_watchdog() in your daemon is enough to hook it up with the watchdog logic.

event source That way the even source callback is run with the zombie process still around so that it can access /proc/$PID/ and similar, and so that it can be sure that the PID has not been reused yet.

2013-12-10bus: introduce "trusted" bus concept and encode access control in object vtablesLennart Poettering
Introduces a new concept of "trusted" vs. "untrusted" busses. For the latter libsystemd-bus will automatically do per-method access control, for the former all access is automatically granted. Per-method access control is encoded in the vtables: by default all methods are only accessible to privileged clients. If the SD_BUS_VTABLE_UNPRIVILEGED flag is set for a method it is accessible to unprivileged clients too. By default whether a client is privileged is determined via checking for its CAP_SYS_ADMIN capability, but this can be altered via the SD_BUS_VTABLE_CAPABILITY() macro that can be ORed into the flags field of the method. Writable properties are also subject to SD_BUS_VTABLE_UNPRIVILEGED and SD_BUS_VTABLE_CAPABILITY() for controlling write access to them. Note however that read access is unrestricted, as PropertiesChanged messages might send out the values anyway as an unrestricted broadcast. By default the system bus is set to "untrusted" and the user bus is "trusted" since per-method access control on the latter is unnecessary. On dbus1 busses we check the UID of the caller rather than the configured capability since the capability cannot be determined without race. On kdbus the capability is checked if possible from the attached meta-data of a message and otherwise queried from the sending peer. This also decorates the vtables of the various daemons we ship with these flags.
2013-12-10test: rework run_qemuRonny Chevalier
It tries to find a suitable QEMU binary and will use KVM if present. We can now configure QEMU from outside with 4 variables : - $QEMU_BIN : path to QEMU's binary - $KERNEL_APPEND : arguments appended to kernel cmdline - $KERNEL_BIN : path to a kernel Default /boot/vmlinuz-$KERNEL_VER - $INITRD : path to an initramfs Default /boot/initramfs-${KERNEL_VER}.img - $QEMU_SMP : number of CPU simulated by QEMU. Default 1 (from Alexander Graf's script: http://www.spinics.net/lists/kvm/msg72389.html)

2013-11-30bus: do kdbus only if this is enabled on the configure switchLennart Poettering
Since we want to retain the ability to break kernel ←→ userspace ABI after the next release, let's not make use by default of kdbus, so that people with future kernels will not suddenly break with current systemd versions. kdbus support is left in all builds but must now be explicitly requested at runtime (for example via setting $DBUS_SESSION_BUS). Via a configure switch the old behaviour can be restored. In fact, we change autogen.sh to do this, so that git builds (which run autogen.sh) get kdbus by default, but tarball builds (which ue the configure defaults) do not get it, and hence this stays out of the distros by default.

2013-11-21bus: rework message handlers to always take an error argumentLennart Poettering
Message handler callbacks can be simplified drastically if the dispatcher automatically replies to method calls if errors are returned. Thus: add an sd_bus_error argument to all message handlers. When we dispatch a message handler and it returns negative or a set sd_bus_error we send this as message error back to the client. This means errors returned by handlers by default are given back to clients instead of rippling all the way up to the event loop, which is desirable to make things robust. As a side-effect we can now easily turn the SELinux checks into normal function calls, since the method call dispatcher will generate the right error replies automatically now. Also, make sure we always pass the error structure to all property and method handlers as last argument to follow the usual style of passing variables for return values as last argument.

2013-11-20core: convert PID 1 to libsystemd-busLennart Poettering
This patch converts PID 1 to libsystemd-bus and thus drops the dependency on libdbus. The only remaining code using libdbus is a test case that validates our bus marshalling against libdbus' marshalling, and this dependency can be turned off. This patch also adds a couple of things to libsystem-bus, that are necessary to make the port work: - Synthesizing of "Disconnected" messages when bus connections are severed. - Support for attaching multiple vtables for the same interface on the same path. This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus calls which used an inappropriate signature. As a side effect we will now generate PropertiesChanged messages which carry property contents, rather than just invalidation information.
