./test-dhcp-client would attempt to operate fd 0, i.e. stdin.
For example, './test-dhcp-client </dev/null' would fail with EPERM
because /dev/null cannot be used with epoll.

After all it is now much more like strjoin() than strappend(). At the
same time, add support for NULL sentinels, even if they are normally not
necessary.

Let's return the fd we found as return value in systemd_netlink_fd(),
instead of using call-by-reference.

When booting with systemd-bootchart, default to call the systemd binary
rather than the init binary on disk, which might be another init system.
Collecting data only works with booting systemd.

On my computer, the minimum brightness enforced by clamping in
backlight is too bright.
Let udev property ID_BACKLIGHT_CLAMP control whether the brightness
is clamped or not.

Simplify the check from commit 05f73ad to only apply the warning to regular
files instead of enumerating device nodes.
|
|
Using /dev/urandom as a key is valid for swap, do not
warn if this devices are world readable.
|
|
Still keep the non-socket activation code around for starting from the commandline, but
will likely drop that too in the future.
|

|
|
Default to timing out after 120 seconds without a network connection. Setting a
timeout of 0 disables the timeout.
|
|
In both cases exit the event loop.

From fd.o bug 88898:
systemd-resolved fails to start:
Failed to drop capabilities: Operation not permitted
Broken in f11943c53ec181829a821c6b27acf828bab71caa.
Drop all capabilities:
1. prctl(PR_SET_KEEPCAPS, keep_capabilities != 0) // 0 when we drop all
capabilities
2. setresuid() // bye bye capabilities
3. Add CAP_SETPCAP // fails because we have no capabilities
4. Reduce capability bounding set
5. Drop capabilities
6. prctl(PR_SET_KEEPCAPS, 0)
Capabilites should always be kept after setresuid() so that the capability
bounding set can be reduced.

https://bugs.freedesktop.org/show_bug.cgi?id=88898
We must be careful not to leave PR_SET_KEEPCAPS on. We could use the
setresuid() call to drop capabilities, but the rules when capabilities
are dropped are fairly complex, since a transition to non-zero uid must
happen. Let's instead keep the capabilities during setresuid(), and drop
them later.

This was broken when the code was rearranged in "1e2fd62d70ff
core/load-fragment.c: correct argument sign and split up long lines"
|
|
If we scale our buffer to be wide enough for the format string, we
should expect that the calculation was correct.
char_array_0() invocations are removed, since snprintf nul-terminates
the output in any case.
A similar wrapper is used for strftime calls, but only in timedatectl.c.

In the test, p is a path to a directory, always absolute. dent->d_name
is a single path component, so they cannot be equal. The comparison
was wrong also for other reasons: D type supports globs, so direct
comparisons using streq are not enough.

We would otherwise wait for the interface to be completely configured, which
could take considerable time with IPv4LL. As a result nspawn was very slow
at obtaining IP addresses.
|
|
In addition to the loopback device, also explicitly configured devices to be ignored.
Suggested by Charles Devereaux <systemd@guylhem.net>.

As in sd-bus, simply log at debug level when a callback fails, but don't fail the event handler.
Otherwise any error returned by any callback will disable the rtnl event handler. We should
only do that on serious internal errors in sd-rtnl that we know cannot be recovered from.

This might be fixed one day, but for now it's better to fail.

This reverts commit b914ea8d379b446c4c9fac4ba181771676ef38cd.
We really need to put a limit on all our resources, everywhere, and in
particular if we operate on external data.
Hence, let's reintroduce the limit, but bump it substantially, so that
it is guaranteed to be higher than any realistic RLIMIT_NOFILE setting.

It may happen that you have several sessions with the same VT:
- Open a session c1 which leaves some processes around, and log out. The
session will stay in State=closing and become Active=no.
- Log back in on the same VT, get a new session "c2" which is State=active and
Active=yes.
When restarting logind after that, the first session that matches the current
VT becomes Active=yes, which will be c1; c2 thus is Active=no and does not get
the usual polkit/device ACL privileges.
Restore the "closing" state in session_load(), to avoid treating all restored
sessions as State=active. In seat_active_vt_changed(), prefer active sessions
over closing ones if more than one session matches the current VT.
Finally, fix the confusing comment in session_load() and explain it a bit
better.

Add unit dependencies for dynamic (i. e. not from fstab) mounts. With that,
mount units properly bind to their underlying device, and thus get
automatically stopped/unmounted when the underlying device goes away.
This cleans up stale mounts from unplugged devices.
Thanks to Lennart Poettering for pointing out the fix!

changing unit state
Unit _start() and _stop() implementations can fail with -EAGAIN to delay
execution temporarily. Thus, we should not output status messages before
invoking these calls, but after, and only when we know that the
invocation actually made a change.

Commit 4e48855534 caused the .sh suffix to be stripped from the original
"filename", which caused the generated units to call the wrong init.d script.
Only use the .sh stripped file name for comparing with Provides:, not for
generating the Exec*= lines.
Spotted by sysv-generator-test.
