2014-02-17core: fixate show_status earlier, so that we actually print the welcome messageLennart Poettering
Previously, we'd fixed show_state only after printing the welcome message which had the effect that the welcome message was almost always suppressed.

2014-02-17Pass log config from systemd to systemd-shutdownZbigniew Jędrzejewski-Szmek
If PID 1 debug logging is enabled, it is nice to keep those settings when switching to systemd-shutdown binary, independently of whether this was done through /proc/cmdline options, or through runtime manipulations.
2014-02-17Extract looping over /proc/cmdline into a shared functionZbigniew Jędrzejewski-Szmek
In cryptsetup-generator automatic cleanup had to be replaced with manual cleanup, and the code gets a bit longer. But existing code had the issue that it returned negative values from main(), which was wrong, so should be reworked anyway.

2014-02-14core: fix detection of dead processesYuxuan Shui
Commit 5ba6985b moves the UNIT_VTABLE(u)->sigchld_event before systemd actually reaps the zombie. Which leads to service_load_pid_file accepting zombie as a valid pid. This fixes timeouts like: [ 2746.602243] systemd[1]: chronyd.service stop-sigterm timed out. Killing. [ 2836.852545] systemd[1]: chronyd.service still around after SIGKILL. Ignoring. [ 2927.102187] systemd[1]: chronyd.service stop-final-sigterm timed out. Killing. [ 3017.352560] systemd[1]: chronyd.service still around after final SIGKILL. Entering failed mode.
2014-02-14shared: include root when canonicalizing conf pathsMichael Marineau
The conf_files_list family accepts an alternate root path to prefix all directories in the list but path_strv_canonicalize_uniq doesn't use it. This results in the suspicious behavior of resolving directory symlinks based on the contents of / instead of the alternate root. This adds a prefix argument to path_strv_canonicalize which will now prepend the prefix, if given, to every path in the list. To avoid answering what a relative path means when called with a root prefix path_strv_canonicalize is now path_strv_canonicalize_absolute and only considers absolute paths. Fortunately all users of already call path_strv_canonicalize with a list of absolute paths.

This allows customization of the arguments used by less. The main motivation is that some folks might not like having --no-init on every invocation of less.

2014-02-10exec: Add SELinuxContext configuration itemMichael Scherer
This permit to let system administrators decide of the domain of a service. This can be used with templated units to have each service in a différent domain ( for example, a per customer database, using MLS or anything ), or can be used to force a non selinux enabled system (jvm, erlang, etc) to start in a different domain for each service.
2014-02-08core: do not print invalid utf-8 in error messagesZbigniew Jędrzejewski-Szmek
2014-02-08core: fix crashes if locale.conf contains invalid utf-8 stringGoffredo Baroncelli
In the parse_env_file_push() and load_env_file_push() functions, there are two assert() call to check if the key or value parameters are utf8 valid. If the strings aren't utf8 valid, assert does abort. These function are used early by systemd to parse some files. For example '/etc/locale.conf'. In my case this file contained a not utf8 sequence, which is bad, but systemd crashed during the boot, which is even worse! The enclosed patch removes the assert and return -EINVAL if the sequence is invalid. This is possible because the caller of these function [1] checks the errors. So the check of an invalid utf8 sequence is still performed, but systemd doesn't crash anymore and logs the error. [1] parse_env_file_internal(), invoked by load_env_file() and parse_env_file()

2014-01-31use memzero(foo, length); for all memset(foo, 0, length); callsGreg KH
In trying to track down a stupid linker bug, I noticed a bunch of memset() calls that should be using memzero() to make it more "obvious" that the options are correct (i.e. 0 is not the length, but the data to set). So fix up all current calls to memset(foo, 0, length) to memzero(foo, length).

2014-01-30sd-dhcp-client/net-util: make netmask_to_prefixlen genericTom Gundersen
This was originally included in the dhcp-client at my request, but it is not really dhcp-specific and useful outside of it, so let's pull it out.

Error out if the address family is already set to something incompatible with the address being parsed.

2014-01-28Base mkostemp_safe on mkostempZbigniew Jędrzejewski-Szmek
It is nice to wrap umask handling and return convention, but glibc's mkostemp is async-signal-safe already.
2014-01-28Get rid of write_safeZbigniew Jędrzejewski-Szmek
Current glibc implementation is safe. Kernel does this atomically, and write is actually implemented through writev. So if write is async-signal-safe, than writev pretty much must be too.
2014-01-28always use the same code for creating temporary filesLennart Poettering
Let's unify our code here, and also always specifiy O_CLOEXEC.

2014-01-27manager: add systemd.show_status=auto modeZbigniew Jędrzejewski-Szmek
When set to auto, status will shown when the first ephemeral message is shown (a job has been running for five seconds). Then until the boot or shutdown ends, status messages will be shown. No indication about the switch is done: I think it should be clear for the user that first the cylon eye and the ephemeral messages appear, and afterwards messages are displayed. The initial arming of the event source was still wrong, but now should really be fixed.
2014-01-27journal: guarantee async-signal-safety in sd_journald_sendvZbigniew Jędrzejewski-Szmek
signal(7) provides a list of functions which may be called from a signal handler. Other functions, which only call those functions and don't access global memory and are reentrant are also safe. sd_j_sendv was mostly OK, but would call mkostemp and writev in a fallback path, which are unsafe. Being able to call sd_j_sendv in a async-signal-safe way is important because it allows it be used in signal handlers. Safety is achieved by replacing mkostemp with open(O_TMPFILE) and an open-coded writev replacement which uses write. Unfortunately, O_TMPFILE is only available on kernels >= 3.11. When O_TMPFILE is unavailable, an open-coded mkostemp is used. https://bugzilla.gnome.org/show_bug.cgi?id=722889
2014-01-27Replace mkostemp+unlink with open(O_TMPFILE)Zbigniew Jędrzejewski-Szmek
This will only work on Linux >= 3.11, and probably not on all filesystems. Fallback code is provided.
2014-01-27bus: add API calls for connecting to starter busLennart Poettering
Add new calls sd_bus_open() and sd_bus_default() for connecting to the starter bus a service was invoked for, or -- if the process is not a bus-activated service -- the appropriate bus for the scope the process has been started in.

2014-01-20exec: introduce PrivateDevices= switch to provide services with a private /devLennart Poettering
Similar to PrivateNetwork=, PrivateTmp= introduce PrivateDevices= that sets up a private /dev with only the API pseudo-devices like /dev/null, /dev/zero, /dev/random, but not any physical devices in them.

2014-01-11journald: do not free space when disk space runs lowZbigniew Jędrzejewski-Szmek
Before, journald would remove journal files until both MaxUse= and KeepFree= settings would be satisfied. The first one depends (if set automatically) on the size of the file system and is constant. But the second one depends on current use of the file system, and a spike in disk usage would cause journald to delete journal files, trying to reach usage which would leave 15% of the disk free. This behaviour is surprising for the user who doesn't expect his logs to be purged when disk usage goes above 85%, which on a large disk could be some gigabytes from being full. In addition attempting to keep 15% free provides an attack vector where filling the disk sufficiently disposes of almost all logs. Instead, obey KeepFree= only as a limit on adding additional files. When replacing old files with new, ignore KeepFree=. This means that if journal disk usage reached some high point that at some later point start to violate the KeepFree= constraint, journald will not add files to go above this point, but it will stay (slightly) below it. When journald is restarted, it forgets the previous maximum usage value, and sets the limit based on the current usage, so if disk remains to be filled, journald might use one journal-file-size less on each restart, if restarts happen just after rotation. This seems like a reasonable compromise between implementation complexity and robustness.
