This make all counters count both bytes of memory and unix fds.

This adds two new directives to the auth protocol:
NEGOTIATE_UNIX_FD is sent by the client after the authentication was
sucessful, i.e. OK was received.
AGREE_UNIX_FD is then sent by the server if it can do unix fd passing as
well.
ERROR is returned when the server cannot or is unwilling to do unix fd
passing.
This should be compatible with existing D-Bus implementations which will
naturally return ERROR on NEGOTIATE_UNIX_FD.

When appending unix fds to the message a new entry in the fd array will
be allocated and the index to it will be written to the message payload.
When parsing unix fds from the message the index will be read from the
payload and then looked up in the fd array.
When we read fds we put them in a queue first. Since each message knows
how many fds are attached to it we will then pop enough fds from this
queue each time we decode a message from the stream.
This should make sending and receiving more portable since we don't make
any strong requirements on the exact semantics of the SCM_RIGHTS
implementation: as long as fds are recieved in order, none or lost and
the arrive at the same time as at least one byte from the actual message
dat we should be able to handle them correctly.

This patch makes various things that should be static static,
corrects some "return FALSE" where it should be NULL, etc.

* tools/dbus-launch-x11.c:
* tools/dbus-launch.1: Add the --autolaunch option to
dbus-launch, which makes it scan for an existing session
started with --autolaunch. With that option, it also creates
an X11 window and saves the bus address and PID to it.
* dbus/dbus-sysdeps.h:

a function that runs "dbus-launch --autolaunch" to retrieve
the running D-Bus session address (or start one if none was running)

address protocol, which tries to get the running session from
dbus-launch.

Attempt auditing public API to remove all cases where a Unix
function returns weird emulated goo to Windows. This probably
breaks the bus daemon on Windows, to fix it again we may
need to stop processing unix-specific config options on Windows,
and may need to add Windows-specific public API or config options.
* configure.in (LT_CURRENT, LT_AGE): increment current and age,
to reflect added interfaces; should not break soname.
* dbus/dbus-transport.c (_dbus_transport_get_is_authenticated): do
not invoke unix user function on Windows. Kind of a hacky fix, but
we don't want a "unix uid" leaking out on Windows.
* dbus/dbus-connection.c (dbus_connection_get_socket): add new API
to get the socket fd on Windows or UNIX
(dbus_connection_get_unix_fd): make this always fail on Windows

* dbus/dbus-server.c (dbus_server_listen): change how this works
to be able to delegate to a set of handlers that can succeed,
fail, or choose not to handle. Allows us to have
dbus_server_listen_platform_specific.
* dbus/dbus-server-socket.c (_dbus_server_new_for_tcp_socket):
factor out the tcp socket stuff to be used on windows, leaving
unix domain socket only in dbus-socket-unix.c

(_dbus_transport_new_for_tcp_socket): factor out the tcp socket
stuff to be used on windows, leaving unix domain socket only

temporary hack to be sure this fails on windows

The primary change here is to always write() once before adding
the write watch, which gives us about a 10% performance increase.
* dbus/dbus-transport-unix.c: a number of modifications to cope
with removing messages_pending
(check_write_watch): properly handle
DBUS_AUTH_STATE_WAITING_FOR_MEMORY; adapt to removal of
messages_pending stuff
(check_read_watch): properly handle WAITING_FOR_MEMORY and
AUTHENTICATED cases
(unix_handle_watch): after writing, see if the write watch can be
removed
(unix_do_iteration): assert that write_watch/read_watch are
non-NULL rather than testing that they aren't, since they
aren't allowed to be NULL. check_write_watch() at the end so
we add the watch if we did not finish writing (e.g. got EAGAIN)
* dbus/dbus-transport-protected.h: remove messages_pending call,
since it resulted in too much inefficient watch adding/removing;
instead we now require that the transport user does an iteration
after queueing outgoing messages, and after trying the first
write() we add a write watch if we got EAGAIN or exceeded our
max bytes to write per iteration setting
* dbus/dbus-string.c (_dbus_string_validate_signature): add this
function
* dbus/dbus-server-unix.c (unix_finalize): the socket name was
freed and then accessed, valgrind flagged this bug, fix it
* dbus/dbus-message.c: fix several bugs where HEADER_FIELD_LAST was taken
as the last valid field plus 1, where really it is equal to the
last valid field. Corrects some message corruption issues.
* dbus/dbus-mainloop.c: verbosity changes
* dbus/dbus-keyring.c (_dbus_keyring_new_homedir): handle OOM
instead of aborting in one of the test codepaths
* dbus/dbus-internals.c (_dbus_verbose_real): fix a bug that
caused not printing the pid ever again if a verbose was missing
the newline at the end
(_dbus_header_field_to_string): add HEADER_FIELD_SIGNATURE
* dbus/dbus-connection.c: verbosity changes;
(dbus_connection_has_messages_to_send): new function
(_dbus_connection_message_sent): no longer call transport->messages_pending
(_dbus_connection_send_preallocated_unlocked): do one iteration to
try to write() immediately, so we can avoid the write watch. This
is the core purpose of this patchset
(_dbus_connection_get_dispatch_status_unlocked): if disconnected,
dump the outgoing message queue, so nobody will get confused
trying to send them or thinking stuff is pending to be sent
* bus/test.c: verbosity changes
* bus/driver.c: verbosity/assertion changes
* bus/dispatch.c: a bunch of little tweaks to get it working again
because this patchset changes when/where you need to block.
|
|
|
|
|

* COPYING: switch to Academic Free License version 2.1 instead of
2.0, to resolve complaints about patent termination clause.

ALLOWED_MECHS to auth-script format so we can set the list of
allowed mechanisms.
* data/auth/client-out-of-mechanisms.auth-script: New test to
check client disconnects when it is out of mechanisms to try.

disconnect message only if the transport has finished queueing all
its real messages and is disconnected.

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)

Unbreak my code...
* dbus/dbus-transport.c (_dbus_transport_get_dispatch_status):
report correct status if we finish processing authentication
inside this function.
* bus/activation.c (try_send_activation_failure): use
bus_transaction_send_error_reply
* bus/connection.c (bus_connection_get_groups): return an error
explaining the problem
* bus/bus.c (bus_context_check_security_policy): implement
restriction here that inactive connections can only send the
hello message. Also, allow bus driver to send anything to
any recipient.
* bus/connection.c (bus_connection_complete): create the
BusClientPolicy here instead of on-demand.
(bus_connection_get_policy): don't return an error
* dbus/dbus-message.c (dbus_message_new_error_reply): allow NULL
sender field in message being replied to
* bus/bus.c (bus_context_check_security_policy): fix silly typo
causing it to return FALSE always
* bus/policy.c (bus_client_policy_check_can_send): fix bug where
we checked sender rather than destination

* dbus/dbus-transport.c (_dbus_transport_get_unix_user): fix bug
where we used >= 0 instead of != DBUS_UID_UNSET.

users
* dbus/dbus-transport.c (_dbus_transport_get_dispatch_status):
fix to only recover unused bytes if we're already authenticated

* bus/bus.c (bus_context_check_security_policy): new
* bus/dispatch.c (send_service_nonexistent_error): delete this,
now we just set the DBusError and it gets converted to an error
reply.

user/group connection perms

* bus/dispatch.c: lots of fixes
* dbus/dbus-mainloop.c (_dbus_loop_dispatch): export
(_dbus_loop_iterate): remove old "quit if no callbacks" code,
that was crack, broke the test service.
* dbus/dbus-transport.c (_dbus_transport_open): fix error
handling to avoid piling up errors if we get a failure on the
first address.
* dbus/dbus-internals.c (_dbus_real_assert_not_reached): include
pid in assertion failures.
* dbus/dbus-mainloop.c (_dbus_loop_iterate): use static arrays up
to some fixed size of file descriptor array. Don't return TRUE
anytime a timeout exists, that led to lots of busy loop silliness
in the tests.

the message bus address
