2014-12-30systemctl: do not repeat hibernate/sleep attemptsZbigniew Jędrzejewski-Szmek
If some sleep operation was not possible (e.g. because swap is missing), we would try twice: once through logind, which would result in a clean error: Failed to execute operation: Sleep verb not supported and then second time by starting the appropriate unit directly, which is more messy. If logind tells us that something is not possible (or already in progress), report that to the user and quit. If logind is present and working we should not try to work around it. Loosely based on https://bugs.freedesktop.org/show_bug.cgi?id=87832.
2014-12-30bus: replace ENOSYS return codes with EBADR/ENOTSUPZbigniew Jędrzejewski-Szmek
ENOSYS is used to signify compiled-out functionality. Using it for different kinds of error is misleading. For BUS_ERROR_SLEEP_VERB_NOT_SUPPORTED, logind-action.c uses ENOTSUP already, so changing it to ENOTSUP makes the dbus and action paths behave the same.

2014-12-30bus: add sd_bus_emit_object_{added/removed}()David Herrmann
This implements two new helpers, discussed on systemd-devel about 1 year ago: sd_bus_emit_object_added() sd_bus_emit_object_removed() Both calls are equivalent to their respective counterpart sd_bus_emit_interfaces_{added/removed}(), but can figure out the list of interfaces themselves, instead of requiring the caller to provide them. Furthermore, both calls properly deal with builtin interfaces provided via org.freedesktop.DBus.* and alike. Both calls simply traverse a node and all its parent nodes to figure out a list of all interfaces registered as vtable or fallback. It then appends each of them, similar to the interfaces_{added/removed}() helpers. Note that interfaces_{added/removed}() runs a parent traversal for *each* passed interface. Therefore, it can simply bail out, once it found a parent node that implements a given interface. With object_{added/removed}() we cannot know the registered interfaces in advance, thus, we cannot run one traversal per node. Instead, we run a single traversal and remember all interfaces that we added. Therefore, a child-interface overrides all conflicting parent-interfaces. We keep a "Set *s" context to track those while climbing up the tree.
2014-12-30bus: fix capabilities on big-endianDavid Herrmann
The kernel provides capabilities as a u32 array, sd-bus uses an u8 array. This works fine on little-endian as both are encoded the same way. However, this fails on big-endian if we do not perform sufficient byte-swapping on each u32 entry. This patch makes sd-bus use u32, too. We avoid changing any kernel provided data so we can keep pointing into kdbus pool buffers which contain u32 arrays.
2014-12-30bus: drop creds->capability_sizeDavid Herrmann
The number of available caps can be read from /proc/sys/kernel/cap_last_cap during runtime. Our helper cap_last_cap() does that, so there's no reason to remember the size of any capability cache. We can just pre-allocate arrays with a suitable size for all available caps and reject any higher caps. The kernel capability API uses u32 as base so make sure we do the same. Note that this is specified by POSIX, so it's unlikely to change.
2014-12-30macro: add DIV_ROUND_UP()David Herrmann
This macro calculates A / B but rounds up instead of down. We explicitly do *NOT* use: (A + B - 1) / A as it suffers from an integer overflow, even though the passed values are properly tested against overflow. Our test-cases show this behavior. Instead, we use: A / B + !!(A % B) Note that on "Real CPUs" this does *NOT* result in two divisions. Instead, instructions like idivl@x86 provide both, the quotient and the remainder. Therefore, both algorithms should perform equally well (I didn't verify this, though).
2014-12-29Revert "machined: don't force terminate registered machines"Lennart Poettering
This reverts commit 206e7a5f7b55ac61188efd895e65ab26e478cbb2. We actually want to allow shutting down containers that use RegisterMachine() rather than CreateMachine() to register their own unit. It should be safe to do so, since the primary usecase for RegisterMachine() are container managers that run only a single container within their own unit, such as systemd-nspawn.
2014-12-29machined: ignore spurious errorLennart Poettering
2014-12-29nspawn: report back to systemd only very late whether we are OKLennart Poettering
That way, systemd can actually figure out if everything is OK with nspawn.
2014-12-29machinectl: add "enable" and "disable" verbs for enabling/disabling ↵Lennart Poettering
systemd-nspawn for containers This is basically just a shortcut for "systemctl enable systemd-nspawn@<foobar>.service", but does escaping.
2014-12-29machinectl: add new "start" verb to start a container as a service in nspawnLennart Poettering
2014-12-29bus-proxy: fix sd_bus_reply_*() usageDavid Herrmann
We *must* not use sd_bus_reply_*() as it does not set the sender field correctly. Use the synthetic_reply_*() helpers instead!
2014-12-29capability: use /proc/sys/kernel/cap_last_capDavid Herrmann
This file was introduced with linux-3.2, use it instead of probing for it via prctl(PR_CAPBSET_READ). For now, keep the old code for backwards compat. We can drop it once 3.2 is our lowest requirement. The test-cap-list code is extended to verify cap_last_cap() is the same as we'd get via prctl probing and /proc.

2014-12-29bus: fix typoDavid Herrmann
Drop spurious 'we'.
2014-12-29rtnl: recv_message - don't enforce sender uidTom Gundersen
All we care about is that the kernel (pid==0) sent the message. Verifying the sender uid seems to break when using userns. Reported by Stéphane Graber.
2014-12-29test: loopback - parse logging env varTom Gundersen
2014-12-29sd-rtnl: rtnl_call - don't dispatch wqueue after timeout has passedTom Gundersen
Only a minor change as the timeout would be hit soon thereafetr at the next loop.
2014-12-29sd-rtnl: rtnl_poll - fix typoTom Gundersen
This caused rtnl_poll to always return true immediately in sd_rtnl_call().
2014-12-29sd-rtnl: recv_message - drop message when peeking failsTom Gundersen
Read the message form the socket or we will loop trying to read the same message repeatedly.
2014-12-29sd-rtnl: recv_message - don't fail on interruptTom Gundersen
We should just try again instead.
2014-12-29sd-rtnl: recv_message - log when dropping messageTom Gundersen
We drop messages received from the wrong uid/pid, log this at debug level.
2014-12-28core: loopback - simplify check_loopback()Tom Gundersen
We no longer configure the addresses on the loopback interface, but simply bring it up and let the kernel do the rest. Also change the check to only check if the interface is up, rather than checking for the IPv4 loopback address.

2014-12-27Fix check_loopback()Stéphane Graber
Add missing htonl() so that check_loopback() actually tests for 127.0.0.1 instead of 1.0.0.127 on little-endian machines.
