* Mediation of processes eavesdroppingTyler Hicks2015-02-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | When an AppArmor confined process wants to eavesdrop on a bus, a check is performed to see if the action should be allowed. The check is based on the connection's label and the bus type. This patch adds a new hook, which was not previously included in the SELinux mediation, to mediate eavesdropping from bus_driver_handle_add_match(). A new function is added to bus/signals.c to see if a match rule is an eavesdropping rule since the rule flags field is private to signals.c. An example AppArmor rule that would allow a process to eavesdrop on the session bus would be: dbus eavesdrop bus=session, Bug: https://bugs.freedesktop.org/show_bug.cgi?id=75113 Signed-off-by: Tyler Hicks <tyhicks@canonical.com> Reviewed-by: Simon McVittie <simon.mcvittie@collabora.co.uk>

* Do not allow eavedropping unless rule owner explicitely declare itCosimo Alfarano2011-07-111-8/+17
| | | | | | | | | | | | | Adds "eavesdrop=true" as a match rule, meaning that the owner intend to eavedrop. Otherwise the owner will receive only broadcasted messages and the ones meant to be delivered to it.

* Rename path_prefix to path_namespace and disallow trailing '/'Simon McVittie2011-04-071-11/+10
| | | | | | | | | Also disallow having both path and path_namespace in the same match rule (it wouldn't make sense, path is more specific than path_namespace). As per IRC discussion with davidz and wjt. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=34870

* signals.h: rename argument in declaration to match implementationSimon McVittie2011-04-071-1/+1

* Supporting matching argument 0 as a namespaceWill Thompson2010-11-231-1/+2
| | | | | | | | | | | | Rather like "arg0path='/foo/'" matching all object paths starting with "/foo/", this adds support for matching a prefix of a string argument with "arg0namespace='org.freedesktop.Telepathy.Client.'" (for example). This is mostly intended for use with NameOwnerChanged and PropertiesChanged; thus, only matching the 0th argument is permitted. (This also means it could work with the multicast-plus-socket-filters model being considered for DBus-in-the-kernel without having to hash every period-separated prefix of every string argument.)

Get matching rules mostly working in the bus; only actually parsing the rule text remains. However, the client side of "signal connections" hasn't been started, this patch is only the bus side. * dbus/dispatch.c: fix for the matching rules changes * bus/driver.c (bus_driver_handle_remove_match) (bus_driver_handle_add_match): send an ack reply from these method calls * glib/dbus-gproxy.c (dbus_gproxy_begin_call): fix order of arguments, reported by Seth Nickell * bus/config-parser.c (append_rule_from_element): support eavesdrop=true|false attribute on policies so match rules can be prevented from snooping on the system bus. * bus/dbus-daemon-1.1.in: consistently use terminology "sender" and "destination" in attribute names; fix some docs bugs; add eavesdrop=true|false attribute * bus/driver.c (bus_driver_handle_add_match) (bus_driver_handle_remove_match): handle AddMatch, RemoveMatch messages * dbus/dbus-protocol.h (DBUS_SERVICE_ORG_FREEDESKTOP_BROADCAST): get rid of broadcast service concept, signals are just always broadcast * bus/signals.c, bus/dispatch.c, bus/connection.c, bus/bus.c: mostly implement matching rules stuff (currently only exposed as signal connections)
