17df7223be core: rework syscall filter
- 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.

Since we do not need to use any flags, include "%" in the format instead
of excluding it like PRI* macros.

693eb9a2d4 bus: rename message "serial" to "cookie"
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.

Daniel Mack
294c866023 Add bus-driverd
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.

626851be97 bus: do kdbus only if this is enabled on the configure switch
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.

6aad7f2cd7 build: Allow disabling maintainer mode
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.

3c9317d2d9 build-sys: Add --disable-networkd option
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.

8b197c3a8a Run with a custom SMACK domain (label).
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.

732bfe09ae build-sys: add ./configure --enable-address-sanitizer
Enabling address sanitizer seems like a useful thing, but is quite
tricky. Proper flags have to be passed to CPPFLAGS, CFLAGS and
LDFLAGS, but passing them on the commandline doesn't work because
we tests are done with ld directly, and not with libtool like in
real linking. We might want to fix this, but let's add a handy
way to enable address checking anyway.

1864b0e395 build-sys: don't build python modules after --without-python
The modules should build just fine, but AM_PATH_PYTHON sets
pkgpyexecdir for us. Without that variable we don't know where to
install modules. In addition libtool tries an empty rpath, breaking
the build. Those issues could be fixed or worked around, but we
probably don't have many people who want to avoid using python binary,
but want to compile python modules. If such uses ever come up, this
issue should be revisited.

5c390a4ae0 Add pam configuration to allow user sessions to work out of the box
systemd-logind will start user@.service. user@.service unit uses
PAM with service name 'systemd-user' to perform account and session
managment tasks. Previously, the name was 'systemd-shared', it is
now changed to 'systemd-user'.

Most PAM installations use one common setup for different callers.
Based on a quick poll, distributions fall into two camps: those that
have system-auth (Redhat, Fedora, CentOS, Arch, Gentoo, Mageia,
Mandriva), and those that have common-auth (Debian, Ubuntu, OpenSUSE).
Distributions that have system-auth have just one configuration file
that contains auth, password, account, and session blocks, and
distributions that have common-auth also have common-session,
common-password, and common-account. It is thus impossible to use one
configuration file which would work for everybody. systemd-user now
refers to system-auth, because it seems that the approach with one
file is more popular and also easier, so let's follow that.

3731acf1ac backlight: add minimal tool to save/restore screen brightness across reboots
As many laptops don't save/restore screen brightness across reboots,
let's do this in systemd with a minimal tool, that restores the
brightness as early as possible, and saves it as late as possible. This
will cover consoles and graphical logins, but graphical desktops should
do their own per-user stuff probably.

This only touches firmware brightness controls for now.

a6c0b31d50 build-sys: use pkg-config for python compilation flags
Python 2.7, and 3.2 and higher support querying compilation
flags through pkg-config. This makes python support follow
rules similar to various other optional compilation-time
libraries. New flags are called PYTHON_DEVEL_CFLAGS and
PYTHON_DEVEL_LIBS, because PYTHON (without _DEVEL), is
already used for the python binary name, and things would
be confusing if the same prefix was used for two things.
configure has --disable-python-devel to disable python modules.

One advantage is that CFLAGS for modules gets smaller:
- -I/usr/include/python3.3m -I/usr/include/python3.3m -Wno-unused-result -DDYNAMIC_ANNOTATIONS_ENABLED=1 -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv
+ -I/usr/include/python3.3m
as does LIBS:
- -lpthread -ldl -lutil -lm -lpython3.3m
+ -lpython3.3m

Support for Python 2.6 is removed, but can be easily
restored by using
PYTHON_DEVEL_CFLAGS="$(python2.6-config --cflags)",
etc., as ./configure parameters.
