* Split _dbus_fd_set_close_on_exec into Unix and Windows versionsSimon McVittie2014-09-151-0/+2
| | | | | | | | | | | | | | | | | | | | | On Unix, the thing that can be made close-on-exec is a file descriptor, which is an int. On Windows, the thing that can be made close-on-exec is a HANDLE, which is pointer-sized (but not necessarily a pointer!). In practice, on Windows we only called _dbus_fd_set_close_on_exec() on socket pseudo-file-descriptors (SOCKET, which is an unsigned int); every SOCKET can validly be cast to HANDLE, but not every HANDLE is a SOCKET. Before this commit we used an intptr_t as a sort of fake union { int; HANDLE; }, which just obscures what's going on. In practice, everything that called _dbus_fd_set_close_on_exec() is really platform-specific anyway, so let's just have two separate functions and call this solved.

* Set correct address when using --address=systemd:Simon Peeters2012-10-081-0/+4
| | | | | | | | | | | | | | | When dbus gets launched through systemd, we need to create an address string based on the sockets passed. The _dbus_append_addres_from_socket() function is responsible for extracting the address information from the file-descriptor and formatting it in a dbus friendly way. This fixes bus activation when running dbus under a systemd session. https://bugs.freedesktop.org/show_bug.cgi?id=50962 Signed-off-by: Simon Peeters <peeters.simon@gmail.com>
* transport: add new unixexec transport on UnixLennart Poettering2012-03-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "unixexec:" transport will create a local AF_UNIX socket with socketpair(), then fork and execute a binary on one side with STDIN and STDOUT connected to it and then use the other side. This is useful to implement D-Bus tunneling schemes, for example to get a D-Bus connection to the system bus on a different host, similar how udisks is already doing it. (udisks uses SSH TCP tunneling for this, which is a bit ugly and less secure than this solution). Suggested use is with connection strings like the following: unixexec:path=ssh,argv1=foobar,argv2=system-bus-bridge or: unixexec:path=pkexec,argv1=system-bus-bridge or even: unixexec:path=sudo,argv1=system-bus-bridge The first line would execute the binary 'system-bus-bridge' on host 'foobar' and then pass D-Bus traffic to it. This (hypothetical) bridge binary would then forward the information to the local system bus. The second and third line use this scheme locally to acquire a privileged connection through pkexec resp. sudo: instead of connecting directly to the bus, they use the same bridge binary which will forward all information to the system bus. The arguments of the protocol are 'path' for the first execlp() argument, and argv0, argv1, and so on for the following arguments. argv0 can be left out in which case path will be used.

* sysdeps-unix: introduce dbus_close_all() and make use of it where appropriateLennart Poettering2012-03-121-0/+2
| | | | | | | | This is optimized on Linux and enumerates through /proc/self/fd with a fallback on brute-force closing of fds, in case /proc is not available. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=35230 Reviewed-by: Simon McVittie <simon.mcvittie@collabora.co.uk>

| | | | | | | This patch enables support for Mac OS X's launch daemon for startup as well as sharing of the DBus session bus environment. It includes a LaunchAgent plist for automatic start of the session bus.
