| * unix-fd: add logic to count unix fds the same way as allocated memoryLennart Poettering2009-05-201-6/+2
| | | | | | | | This make all counters count both bytes of memory and unix fds.
| * auth: add fd passing negotiation supportLennart Poettering2009-05-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * unix-fd: add message encoding/decoding for unix fdsLennart Poettering2009-05-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
