The Samba package used by the INVIS server (based on openSUSE) needs
some additional Samba permissions for the added ActiveDirectory /
Kerberos support.
As discussed with Seth, add /var/lib/sss/mc/initgroups read permissions
to abstractions/nameservice instead of only to the smbd profile because
it's probably needed by more than just Samba if someone uses sss.

- change abstractions/postfix-common to allow /etc/postfix/*.db k

Some of the /usr/lib/dovecot/* rules already have mrPx permissions,
while others don't.
With a more recent kernel, I noticed that at least auth, config, dict,
lmtp, pop3 and ssl-params need mrPx instead of just Px (confirmed by the
audit.log and actual breakage caused by the missing mr permissions).
The mr additions for anvil, log and managesieve are just a wild guess,
but I would be very surprised if they don't need mr.

Add several permissions to the dovecot profiles that are needed on ubuntu
(surprisingly not on openSUSE, maybe it depends on the dovecot config?)
As discussed some weeks ago, the added permissions use only /run/
instead of /{var/,}run/ (which is hopefully superfluous nowadays).

nmbd needs some additional permissions:

- w for /var/cache/samba/msg/* (the log didn't indicate any read access)

A while ago, support for "network unspec" was added. However, nobody

Newer kernels need m permissions for the binary the profile covers,
so add it before someone hits this problem in the wild ;-)
Also add a note that the mlmmj-recieve profile is probably superfluous
because upstream renamed the misspelled binary.

This patch updates the mlmmj profiles in the extras directory to the
profiles that are used on lists.opensuse.org now. Besides adding lots
of trailing slashes for directories, several permissions were added.
Also, usr.bin.mlmmj-receive gets added - it seems upstream renamed
mlmmj-recieve to fix a typo.
These profiles were provided by Per Jessen.

These files are needed for disk-based buffering (added in syslog-ng 3.8).
This was reported to me by Peter Czanik, one of the syslog-ng developers.
Note: I'm not sure about adding @{CHROOT_BASE} to this rule, so for now
I prefer not to do it - adding it later is easy, but finding out if it
could be removed is hard ;-)

In 2011 (r1803), the traceroute profile was changed to also match
/usr/bin/traceroute.db:
/usr/{sbin/traceroute,bin/traceroute.db} {
However, permissions for /usr/bin/traceroute.db were never added.
This patch fixes this.
While on it, also change the /usr/sbin/traceroute permissions from
rmix to the less confusing mrix.

Subject: dbus-session-strict: allow access to the user bus socket
If dbus is configured with --enable-user-bus (for example in the
dbus-user-session package in Debian and its derivatives), and the user
session is started with systemd, then the "dbus-daemon --session" will be
started by "systemd --user" and listen on $XDG_RUNTIME_DIR/bus. Similarly,
on systems where dbus-daemon has been replaced with kdbus, the
bridge/proxy used to provide compatibility with the traditional D-Bus
protocol listens on that same socket.
In practice, $XDG_RUNTIME_DIR is /run/user/$uid on all systemd systems,
where $uid represents the numeric uid. I have not used /{var/,}run here,
because systemd does not support configurations where /var/run and /run
are distinct; in practice, /var/run is a symbolic link.
Based on a patch by Sjoerd Simons, which originally used the historical
path /run/user/*/dbus/user_bus_socket. That path was popularized by the
user-session-units git repository, but has never been used in a released
version of dbus and should be considered unsupported.

acmetool is an alternative client for Let's Encrypt.

It stores the certificates etc. in the following directory layout:
/var/lib/acme/live/<domain> -> ../certs/<hash>
/var/lib/acme/certs/<hash>/cert
/var/lib/acme/certs/<hash>/chain
/var/lib/acme/certs/<hash>/privkey -> ../../keys/<hash>/privkey

/var/lib/acme/certs/<hash>/fullchain
/var/lib/acme/keys/<hash>/privkey
This patch adds the needed permissions to the ssl_certs and ssl_keys
abstractions so that the certificates can be used.

dovecot-lda needs to read and write /tmp/dovecot.lda.*.
It also needs to be able to execute sendmail to send sieve vacation
mails.
For now, I'm using a child profile for sendmail to avoid introducing a
new profile with possible regressions. This child profile is based on
the usr.sbin.sendmail profile in extras and should cover both postfix'
and sendmail's sendmail.
I also mixed in some bits that were needed for (postfix) sendmail on my
servers, and dropped some rules that were obsolete (directory rules not
ending with a /) or covered by an abstraction.
In the future, we might want to provide a stand-alone profile for
sendmail (based on this child profile) and change the rule in the
dovecot-lda profile to Px.
