Remove distribution-specific init-scripts

portable between distributions, as evidenced by the presence of both
"Red Hat" and "Slackware" init scripts in dbus. Many distributors
prefer to maintain them downstream, as is done in Debian (and its
derivatives) and in Slackware, so that the init script can follow
OS conventions (for example regarding boot messages) and make use
of OS-provided facilities (for example, the Debian init script uses
dpkg's start-stop-daemon utility).

The Slackware and Red Hat init scripts removed by this commit are not
tested or maintained in practice, and so are likely to have bugs. The
Slackware init-script provided here is not used on actual Slackware
systems, which provide a different implementation of rc.messagebus in
their packaging, while the Red Hat init script has been superseded by
the systemd unit in current Fedora, CentOS and RHEL versions.

The Cgywin messagebus-config provided here does appear to be used in
production in cygwin-ports, but it's full of Cygwin-specifics with which
the dbus maintainers are not familiar, so it is probably more appropriate
for it to be tracked downstream as part of the Cygwin packaging.

The systemd unit is not removed, since it is used on multiple Linux
distributions with little or no modification, and receives regular
testing and maintenance; this makes it appropriate to maintain upstream.

sysdeps: increase listen() backlog of AF_UNIX sockets to SOMAXCONN

Previously, the listen() backlog was set to an arbitrary 30. This means
that if dbus-daemon is overloaded only 30 more connections may be queued
by the kernel, before connect() fails with EAGAIN. (Note that EAGAIN !=
EINPROGRESS -- the latter is what is returned if a connection is queued
and being processed for asynchronous sockets; EAGAIN in this case is
really an error, that cannot be recovered from).

Most software simply sets SOMAXCONN as backlog for AF_UNIX sockets, to
allow queuing of as many connections as the kernel allows. SOMAXCONN is
128 on Linux, which is not particularly high, but at least higher than
30.

This patch changes dbus-daemon to do the same.

I noticed this when flooding dbus-daemon with a lot of connections,
where it pretty quickly ceased to respond, much earlier than it really
should.

Note that the backlog has nothing to do with the number of concurrent
connections allowed, it simply controls how many queued, but not
accept()ed connections there may be on the listening socket.

6 years agouserdb: Respect $HOME for the home directory of our own uid
Simon McVittie [Fri, 28 Jul 2017 07:38:20 +0000 (08:38 +0100)]
userdb: Respect $HOME for the home directory of our own uid

This lets cooperating processes with the same value of $HOME
interoperate for DBUS_COOKIE_SHA1 by reading and writing $HOME, even
if their $HOME differs from the uid's "official" home directory
according to getpwuid(). Out of paranoia, we only do this if the uid
and the euid are equal, since if they were unequal the correct thing
to do would be ambiguous.

In particular, Debian autobuilders run as a user whose "official"
home directory in /etc/passwd is "/nonexistent", as a mechanism to
detect non-deterministic build processes that rely on the contents of
the home directory. Until now, this meant we couldn't run dbus'
build-time tests, because every test that used DBUS_COOKIE_SHA1 would
fail in this environment.

In the tests, set HOME as well as DBUS_TEST_HOMEDIR. We keep
DBUS_TEST_HOMEDIR too, because Windows doesn't use HOME, only HOMEDRIVE
and HOMEPATH.

unwieldy, so let's try something else. Bundle together the send_
attributes, the receive_ attributes, the eavesdrop attribute
(which can go on either send or receive rules) and the other attributes
into equivalence classes, and write the conditionals in terms of those
equivalence classes.

In particular, this correctly forbids
    <allow receive_type="..." send_destination="..."/>
which was previously allowed but nonsensical (the send part took
precedence and the receive part was ignored).
