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.
2014-12-29core: loopback - correctly fail the loopback_check if somehow the rtnl calls ↵Tom Gundersen
fail
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.

2014-12-26journald: always allocate space for object fieldsZbigniew Jędrzejewski-Szmek
If OBJECT_PID= came as the last field, we would not reallocate the iovec to bigger size, and fail the assertion later on in dispatch_message_real().

2014-12-25test: wait for cloned thread to exitFilipe Brandenburger
In test_raw_clone, make sure the cloned thread calls _exit() and in the parent thread call waitpid(..., __WCLONE) to wait for the child thread to terminate, otherwise there is a race condition where the child thread will log to the console after the test process has already exited and the assertion from the child thread might not be enforced. The absence of this patch might also create problems for other tests that would be added after this one, since potentially both parent and child would run those tests as the child would continue running. Tested by confirming that the logs from the child are printed before the test terminates and that a false assertion in the child aborts the test with a core dump. [zj: also add check for the return value.]
