2014-05-26analyze/run: use bus_open_transport_systemd instead of bus_open_transportThomas Bächler
Both systemd-analyze and systemd-run only access org.freedesktop.systemd1 on the bus. This patch allows using systemd-run --user and systemd-analyze --user even if the user session's bus is not properly integrated with the systemd user unit. https://bugs.freedesktop.org/show_bug.cgi?id=79252 and other reports...

2014-05-25nspawn: make nspawn robust to container failureDjalal Harouni
nspawn and the container child use eventfd to wait and notify each other that they are ready so the container setup can be completed. However in its current form the wait/notify event ignore errors that may especially affect the child (container). On errors the child will jump to the "child_fail" label and terminate with _exit(EXIT_FAILURE) without notifying the parent. Since the eventfd is created without the "EFD_NONBLOCK" flag, this leaves the parent blocking on the eventfd_read() call. The container can also be killed at any moment before execv() and the parent will not receive notifications. We can fix this by using cheap mechanisms, the new high level eventfd API and handle SIGCHLD signals: * Keep the cheap eventfd and EFD_NONBLOCK flag. * Introduce eventfd states for parent and child to sync. Child notifies parent with EVENTFD_CHILD_SUCCEEDED on success or EVENTFD_CHILD_FAILED on failure and before _exit(). This prevents the parent from waiting on an event that will never come. * If the child is killed before execv() or before notifying the parent, we install a NOP handler for SIGCHLD which will interrupt blocking calls with EINTR. This gives a chance to the parent to call wait() and terminate in main(). * If there are no errors, parent will block SIGCHLD, restore default handler and notify child which will do execv(), then parent will pass control to process_pty() to do its magic.

2014-05-25nspawn: move container wait logic into wait_for_container()Djalal Harouni
Move the container wait logic into its own wait_for_container() function and add two status codes: CONTAINER_TERMINATED or CONTAINER_REBOOTED. The status will be stored in its argument, this way we handle: a) Return negative on failures. b) Return zero on success and set the status to either CONTAINER_REBOOTED or CONTAINER_TERMINATED. These status codes are used to terminate nspawn or loop again in case of CONTAINER_REBOOTED.

2014-05-25path-util: fix missing terminating zeroTanu Kaskinen
There was this code: if (to_path_len > 0) memcpy(p, to_path, to_path_len); That didn't add the terminating zero, so the resulting string was corrupt if this code path was taken. Using strcpy() instead of memcpy() solves this issue, and also simplifies the code. Previously there was special handling for shortening "../../" to "../..", but that has now been replaced by a path_kill_slashes() call, which also makes the result prettier in case the input contains redundant slashes that would otherwise be copied to the result.

2014-05-24sd-network: avoid false positive compiler warning caused by LTOTom Gundersen
Djalal Harouni <tixxdz@opendz.org>: There is also this one genrated by LTO, IMO it's a false positive since we do *check* for "lease" but the code is not consistent since in that code path, "lease" is initialized to NULL in other places, except for this one: src/resolve/resolved-manager.c: In function 'manager_update_resolv_conf': src/libsystemd-network/sd-dhcp-lease.c:67:18: warning: 'lease' may be used uninitialized in this function [-Wmaybe-uninitialized] if (lease->dns_size) { ^ src/network/sd-network.c:146:24: note: 'lease' was declared here sd_dhcp_lease *lease; ^

2014-05-22core: never consider failure when reading drop-ins fatalLennart Poettering
drop-ins don't carry the main configuration of a unit, hence read them if we can't, complain if we cannot, but don't fail.

2014-05-22nspawn: restore journal directory is empty checkLennart Poettering
This undoes part of commit e6a4a517befe559adf6d1dbbadf425c3538849c9. Instead of removing the error message about non-empty journal bind mount directories, simply downgrade the message to a warning and proceed.
2014-05-22cgroups: simplify CPUQuota= logicLennart Poettering
Only accept cpu quota values in percentages, get rid of period definition. It's not clear whether the CFS period controllable per-cgroup even has a future in the kernel, hence let's simplify all this, hardcode the period to 100ms and only accept percentage based quota values.

2014-05-22nspawn: allow to bind mount journal on top of a non empty container journal ↵Djalal Harouni
dentry Currently if nspawn was called with --link-journal=host or --link-journal=auto and the right /var/log/journal/machine-id/ exists then the bind mount the subdirectory into the container might fail due to the ~/mycontainer/var/log/journal/machine-id/ of the container not being empty. There is no reason to check if the container journal subdir is empty since there will be a bind mount on top of it. The user asked for a bind mount so give it. Note: a next call with --link-journal=guest may fail due to the /var/log/journal/machine-id/ on the host not being empty. https://bugs.freedesktop.org/show_bug.cgi?id=76193 Reported-by: Tobias Hunger <tobias.hunger@gmail.com>
2014-05-22cgroups: always propagate controller membership to siblings, for all controllersLennart Poettering
This is the behaviour the kernel cgroup rework exposes for all controllers, hence let's do this already now for all cases.
2014-05-22cgroup: rework startup logicLennart Poettering
Introduce a (unsigned long) -1 as "unset" state for cpu shares/block io weights, and keep the startup unit set around all the time.
2014-05-22core: add startup resource control optionWaLyong Cho
Similar to CPUShares= and BlockIOWeight= respectively. However only assign the specified weight during startup. Each control group attribute is re-assigned as weight by CPUShares=weight and BlockIOWeight=weight after startup. If not CPUShares= or BlockIOWeight= be specified, then the attribute is re-assigned to each default attribute value. (default cpu.shares=1024, blkio.weight=1000) If only CPUShares=weight or BlockIOWeight=weight be specified, then that implies StartupCPUShares=weight and StartupBlockIOWeight=weight.

2014-05-21logind: don't apply RemoveIPC= to system usersLennart Poettering
We shouldn't destroy IPC objects of system users on logout. http://lists.freedesktop.org/archives/systemd-devel/2014-April/018373.html This introduces SYSTEM_UID_MAX defined to the maximum UID of system users. This value is determined compile-time, either as configure switch or from /etc/login.defs. (We don't read that file at runtime, since this is really a choice for a system builder, not the end user.) While we are at it we then also update journald to use SYSTEM_UID_MAX when we decide whether to split out log data for a specific client.
2014-05-20dhcp-lease: add support for parsing a few more dhcp optionsTom Gundersen
2014-05-20dhcp-lease: refactor lease parsingTom Gundersen
Use helper functions, and add some more sanity checking/asserts.
2014-05-20sd-dhcp: refactor parse_optionsTom Gundersen
Similar to the previous patch, exchange a length and a pointer with only one offset variable. Also fix the type of the options to be uint8_t[], rather than uint8_t*.
2014-05-20sd-dhcp: refactor dhcp_option_appendTom Gundersen
Store a pointer to the options in the DHCPMessage struct, and pass this together with an offset around, rather than a uint8_t**. This avoids us having to (re)compute the pointer; and changes dhcp_option_append from adjusting both the pointer to the next option and the remaining size of the options, to just adjusting the current offset. This makes the code a bit simpler to follow IMHO, but there should be no functional change.
2014-05-21timesyncd: save clock to disk everytime we get an NTP fix, and bump clock at ↵Lennart Poettering
boot using this This is useful to make sure the system clock stays monotonic even on systems that lack an RTC. Also, why we are at it, also use the systemd release time for bumping the clock, since it's a slightly less bad than starting with jan 1st, 1970. This also moves timesyncd into the early bootphase, in order to make sure this initial bump is guaranteed to have finished by the time we start real daemons which might write to the file systemd and thus shouldn't leave 1970's timestamps all over the place...
2014-05-20udevadm-settle: fixed return code for empty queueHarald Hoyer
If the udev queue is empty and "/run/udev/queue" does not exist, "udevadm settle" would return with EXIT_FAILURE, because the inotify on "/run/udev/queue" would fail with ENOENT. This patch lets "udevadm settle" exit with EXIT_SUCCESS in this case.
