2015-03-16core/namespace: fix path sortingMichal Schmidt
The comparison function we use for qsorting paths is overly indifferent. Consider these 3 paths for sorting: /foo /bar /foo/foo qsort() may compare: "/foo" with "/bar" => 0, indifference "/bar" with "/foo/foo" => 0, indifference and assume transitively that "/foo" and "/foo/foo" are also indifferent. But this is wrong, we want "/foo" sorted before "/foo/foo". The comparison function must be transitive. Use path_compare(), which behaves properly. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1184016
2015-03-16shared: add path_compare(), an ordering path comparisonMichal Schmidt
... and make path_equal() a simple wrapper around it.

2015-03-16shared - reinstate plymouth_running()Tom Gundersen
This will be used by fsckd. This reverts part of 031886edfc6e96ab778c241035a8d00fb0de99d3.
2015-03-16core: Remove explicit Plymouth integrationJasper St. Pierre
Even if plymouth is running, it might have not displayed the splash yet, so we'll see a few lines on fbcon when we should have otherwise had nothing. Plymouth integration was added to systemd in commit 6faa11140bf776cdaeb8d22d01816e6e48296971. That same day, Plymouth got systemd integration [0]. As such, the Plymouth integration has always been obsolete, and was probably only for older Plymouth's. But I can't imagine anybody running a Plymouth from 2011 with a systemd from 2015. Remove the Plymouth/systemd integration, and let Plymouth's code tell systemd to print the details.

2015-03-16core: don't change removed devices to state "tentative"Martin Pitt
Commit 628c89c introduced the "tentative" device state, which caused devices to go from "plugged" to "tentative" on a remove uevent. This breaks the cleanup of stale mounts (see commit 3b48ce4), as that only applies to "dead" devices. The "tentative" state only really makes sense on adding a device when we don't know where it was coming from (i. e. not from udev). But when we get a device removal from udev we definitively know that it's gone, so change the device state back to "dead" as before 628c89c.
2015-03-15vconsole-setup: check error of child processLucas De Marchi
If we don't check the error of the child process, systemd-vconsole-setup would exit with 0 even if it could not really setup the console. For a simple test, move loadkeys elsewhere and execute systemd-vconsole-setup: [root@localhost ~]# strace -f -e execve /usr/lib/systemd/systemd-vconsole-setup execve("/usr/lib/systemd/systemd-vconsole-setup", ["/usr/lib/systemd/systemd-vconsol"...], [/* 15 vars */]) = 0 Process 171 attached [pid 171] execve("/usr/bin/loadkeys", ["/usr/bin/loadkeys", "-q", "-C", "/dev/tty0", "br-abnt2"], [/* 15 vars */]) = -1 ENOENT (No such file or directory) [pid 171] +++ exited with 1 +++ --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=171, si_uid=0, si_status=1, si_utime=0, si_stime=0} --- +++ exited with 0 +++ Note that loadkeys returned 1 while systemd-vconsole-setup return 0. Since the font and keyboard setup are already serialized, refactor the code a little bit so the functions do the wait by themselves. One change in behavior in this patch is that we don't return early, but we do try to setup the keyboard even if the font load failed.
2015-03-15network: add UseNTP DHCP optionMichael Marineau
Despite having the internal logic in place to enable/disable using NTP servers provided by DHCP the network config didn't expose the option.

Also use our own mkostemp wrapper, which tries to use O_TMPFILE.
2015-03-15logind: check return value of session_releaseZbigniew Jędrzejewski-Szmek
It allocates memory, so it can fail. CID #1237527.

2015-03-14journald: add syslog fields for audit messagesZbigniew Jędrzejewski-Szmek
Audit messages would be displayed as "unknown[1]". Also specify AUTH as facility... This seems to be the closest match (/* security/authorization messages */).

2015-03-14cryptsetup-generator: remove warning about crypttab access modeZbigniew Jędrzejewski-Szmek
This file contains no privileged data — just names of devices to decrypt and files containing keys. On a running system most of this can be inferred from the device tree anyway.
2015-03-14udev: downgrade "has devpath" and "filled with db file" messagesZbigniew Jędrzejewski-Szmek
Udev debug messages have to be significantly overhauled... For now just downgrade those two. They are responsible for approximately 25% of debug output during boot and are rather useless.

2015-03-14core: do not use quotes around virt and archZbigniew Jędrzejewski-Szmek
Quotes are useful when the string can contain spaces or be otherwise confusing. Not possible with those two.
2015-03-14sysv-generator: initialize LookupPaths just onceZbigniew Jędrzejewski-Szmek
With debugging on, sysv-generator would print the full set of lookup paths for *every* sysv script. While at it, pass LookupPaths as a pointer in sysv-generator, and constify it everywhere.

it is ironic that "The only purpose of this structure is to cast the structure pointer passed in addr in order to avoid compiler warnings. See EXAMPLE below." from bind(2)

sd_event_dispatch() returns 0 on FINISH, so let's eat that up.

2015-03-13selinux: fix SEGV during switch-root if SELinux policy loadedWill Woods
If you've got SELinux policy loaded, label_hnd is your labeling handle. When systemd is shutting down, we free that handle via mac_selinux_finish(). But: switch_root() calls mkdir_p_label(), which tries to look up a label using that freed handle, and so we get a bunch of garbage and eventually SEGV in libselinux. (This doesn't happen in the switch-root from initramfs to real root because there's no SELinux policy loaded in initramfs, so label_hnd is NULL and we never attempt any lookups.) So: make sure that mac_selinux_finish() actually sets label_hnd to NULL, so nobody tries to use it after it becomes invalid. https://bugzilla.redhat.com/show_bug.cgi?id=1185604
2015-03-13sd-daemon: simplify sd_pid_notify_with_fdsZbigniew Jędrzejewski-Szmek
Coverity was complaining that CMSG_NXTHDR is used without checking the return value. In this case it cannot fail, but it is a good excuse to simplify the function a bit. CID #1261726.
2015-03-13udev: properly calculate size of remaining dataZbigniew Jędrzejewski-Szmek
The data comes from the kernel, so chances of it being garbled are low, but for correctness' sake, add the check. CID #996458.

CID #1237550.
2015-03-13core: don't wait for reply if writing to pipe failsZbigniew Jędrzejewski-Szmek
This shouldn't really happen, but it's seems cleaner to continue on error. CID #1237552.
2015-03-13core: either ignore or handle mount failuresZbigniew Jędrzejewski-Szmek
/dev/pts/ptmx is as important as /dev/pts, so error out if that fails. Others seem less important, since the namespace is usable without them, so ignore failures. CID #123755, #123754.
2015-03-13Use space after a silencing (void)Zbigniew Jędrzejewski-Szmek
We were using a space more often than not, and this way is codified in CODING_STYLE.

CID #1237559.
2015-03-13sd-resolve: use different element of union to make code more readableZbigniew Jędrzejewski-Szmek
They both point to the same location, but the reader is not forced to look back to the beginning of the function to see that.

It certainly is everywhere on Linux, but as a courtesy to people doing some strange cross-compilation, check that the assumption holds.
