tcpwrap is legacy code, that is barely maintained upstream. It's APIs
are awful, and the feature set it exposes (such as DNS and IDENT
access control) questionnable. We should not support this natively in
systemd.
Hence, let's remove the code. If people want to continue making use of
this, they can do so by plugging in "tcpd" for the processes they start.
With that scheme things are as well or badly supported as they were from
traditional inetd, hence no functionality is really lost.
If --trust=ca.crt is used, only clients presenting certificates signed
by the ca will be allowed to proceed. No hostname matching is
performed, so any client wielding a signed certificate will be
authorized.
Error functions are moved from journal-gateway to microhttp-util and
made non-static, since now they are used in two source files.
This way each user allocates from his own pool, with its own size limit.
This puts the size limit by default to 10% of the physical RAM size but
makes it configurable in logind.conf.
The release tarballs ship with pre-generated man pages, so we do not
need xsltproc for a typical end-user build.
Developers will probably have xsltproc anyway, but if not they will now
encounter a build-time failure instead of an error in configure.
This permit to switch to a specific apparmor profile when starting a daemon. This
will result in a non operation if apparmor is disabled.
It also add a new build requirement on libapparmor for using this feature.
Debian Stable is still using glibc 2.13, which doesn't provide the setns().
So we detect this and provide a tiny wrapper that issues the setns syscall
towards the kernel.
- Allow configuration of an errno error to return from blacklisted
syscalls, instead of immediately terminating a process.
- Fix parsing logic when libseccomp support is turned off
- Only keep the actual syscall set in the ExecContext, and generate the
string version only on demand.
gold doesn't exhibit the problems with linking of compatibility
libraries.
It is also slightly faster:

It is nicer to predefine patterns using configure time check instead of
using casts everywhere.
Since we do not need to use any flags, include "%" in the format instead
of excluding it like PRI* macros.
Even if the lower-leveld dbus1 protocol calls it "serial", let's expose
the word "cookie" for this instead, as this is what kdbus uses and since
it doesn't imply monotonicity the same way "serial" does.
systemd-bus-driverd is a small daemon that connects to kdbus and
implements the org.freedesktop.DBus interface. IOW, it provides the bus
functions traditionally taken care for by dbus-daemon.
Calls are proxied to kdbus, either via libsystemd-bus (were applicable)
or with the open-coded use of ioctl().
Note that the implementation is not yet finished as the functions to
add and remove matches and to start services by name are still missing.
Since we want to retain the ability to break kernel ←→ userspace ABI
after the next release, let's not make use by default of kdbus, so that
people with future kernels will not suddenly break with current systemd
versions.
kdbus support is left in all builds but must now be explicitly requested
at runtime (for example via setting $DBUS_SESSION_BUS). Via a configure
switch the old behaviour can be restored. In fact, we change autogen.sh
to do this, so that git builds (which run autogen.sh) get kdbus by
default, but tarball builds (which ue the configure defaults) do not get
it, and hence this stays out of the distros by default.
This reverts commit f1a1264d13.
We can turn this off with a pragma only on old gcc. Newer gcc doesn't
need this, so let's not turn this off for everybody.
This allows make rules for generated build files (i.e. configure,
Makefile.in, ... ) to be skipped. This is useful when
the source is stored without timestamps (for example in CVS or GIT).
When the build rules trigger to regenerate the build files, it tries to
use the same autotools version (currently 1.14) as was originally used
for the release. Since many of our build machines run Debian Squeeze,
they only have autotools 1.11 available and the build fails.
Currently, we have to work around this by touching all the generated
files before building to avoid triggering the make rule. With this
patch, we would be able to just run configure with
--disable-maintainer-mode instead. The patch sets the default to enable
to not change the default behavior.

For GNOME (Continuous), we are unlikely to require or want
systemd-networkd in the near term future; all of the tools and code
are targeting NetworkManager.
The long term story is still an open question of course, but for now,
there's no reason for gnome-continuous to build or ship this.
Older gcc versions throw things like:
In file included from /usr/include/fcntl.h:302:0,
from ../src/core/execute.c:25:
In function 'open',
inlined from 'open_null_as' at ../src/core/execute.c:196:12:
/usr/include/bits/fcntl2.h:50:24: error: call to '__open_missing_mode'

__open_missing_mode ();
Allows the systemd --system process to change its current
SMACK label to a predefined custom label (usually "system")
at boot time.
This is needed to have a few system-generated folders and
sockets automatically be created with the right SMACK
label. Without that, processes either cannot communicate with
systemd or systemd fails to perform some actions.
