- Fix CVE-2020-12049: An issue was discovered in dbus >= 1.3.0 before
1.12.18. The DBusServer in libdbus, as used in dbus-daemon, leaks file
descriptors when a message exceeds the per-message file descriptor
limit. A local attacker with access to the D-Bus system bus or another
system service's private AF_UNIX socket could use this to make the
system service reach its file descriptor limit, denying service to
subsequent D-Bus clients.
- Also update indentation in hash file (two spaces)

The D-Bus installation process installs dbus-daemon-launch-helper as
follows:
chown root:$(DBUS_USER) $(DESTDIR)$(libexecdir)/dbus-daemon-launch-helper$(EXEEXT); \
chmod 4750 $(DESTDIR)$(libexecdir)/dbus-daemon-launch-helper$(EXEEXT); \
And when the installation does not take place as root (like is the
case in the context of Buildroot), it prints:
echo "Not installing $(DESTDIR)$(libexecdir)/dbus-daemon-launch-helper binary setuid!"; \
echo "You'll need to manually set permissions to root:$(DBUS_USER) and permissions 4750"; \
So let's adjust the installation logic of dbus-daemon-launch-helper to
match these requirements.

Fixes the following security issues:
- CVE-2019-12749: Do not attempt to carry out DBUS_COOKIE_SHA1
authentication for identities that differ from the user running the
DBusServer. Previously, a local attacker could manipulate symbolic links
in their own home directory to bypass authentication and connect to a
DBusServer with elevated privileges. The standard system and session
dbus-daemons in their default configuration were immune to this attack
because they did not allow DBUS_COOKIE_SHA1, but third-party users of
DBusServer such as Upstart could be vulnerable. Thanks to Joe Vennix of
Apple Information Security.

After c0ad6ded01 expat: security bump to version 2.2.1
the system can hang on startup under certain circumstances.
This happens when:
* we use systemd as init system
* the random nonblocking pool takes a while to initialize
* this apparently doesn't happen on qemu, so this would not have
been caught by the runtime testing infrastructure
* it also doesn't seem to happen when network booting

There was already a post-build hook to delete the /var/lib/dbus symlink
created by buildroot after the package's own installation, to prevent
a dbus installation error during "make dbus-rebuild". However, this
misses the case for when one might delete the .stamp_target_installed
file manually, outside of dbus-rebuild. This can be fixed by changing
the post-build hook to a pre-install hook. This seems appropriate,
since it is really addressing an installation issue, not a build issue.

The latest dbus release 1.10.16 fixes two symlink attacks in
non-production-suitable configurations. I am treating these as bugs
rather than practical vulnerabilities, and very much hope neither of
these is going to affect any real users, but I'm reporting them to
oss-security in case there's an attack vector that I've missed.

As was suggested by the <pkg>_DEPENDENCIES variable, the audit support
in DBus requires both audit and libcap-ng. However, it didn't take
care of the fact that libcap-ng must be enabled in the configuration
to depend on it, causing some build failures with the newly added
check.
DBus configure.ac confirms that both packages are needed to enable
audit support, so we simply fix the condition to only be true when
both BR2_PACKAGE_AUDIT *and* BR2_PACKAGE_LIBCAP_NG are true.

To detect X11 support dbus uses the autoconf macro AC_PATH_XTRA
http://cgit.freedesktop.org/dbus/dbus/tree/configure.ac#n1264
This macro checks for the optional presence of libICE:
http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=blob;f=lib/autoconf/libs.m4;h=d2040d731f81fc1693e01d118c45d51ad169d56a;hb=HEAD#l472
quoting dbus configure with libICE not present:
checking for IceConnectionNumber in -lICE... no
quoting dbus configure with libICE being present:
checking for IceConnectionNumber in -lICE... yes
The binary usr/bin/dbus-launch is being linked to libICE and libSM if
the packages are available:
$ output/host/usr/bin/i586-buildroot-linux-uclibc-readelf -a
output/target/usr/bin/dbus-launch | grep NEEDED
0x00000001 (NEEDED) Shared library: [libdbus-1.so.3]

0x00000001 (NEEDED) Shared library: [libc.so.1]
To get a reproducable build add libSM as optional dependency to dbus,
libSM pulls in the dependency to libICE.

When systemd is used, /var/lib/dbus becomes dangling symlink, because
nobody does mkdir /tmp/dbus, so /var/lib/dbus/machine-id could not be
written. On SysVinit systems there is init script that creates
/tmp/dbus.
This patch preserves old behavior for SysVinit systems, and introduces
new one for systemd-booted systems: /var/lib/dbus is a persistent
directory, it holds symlink /var/lib/dbus/machine-id -> /etc/machine-id
as machine-id(5) suggests, and /etc/machine-id is managed by systemd.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.
