is that for "$XDG_RUNTIME_DIR/dbus-1" ? I would probably use a private type here  (predictable name so name-based type transition is an option) although i do not know what that dir is used for

Yes, this is a very good idea, I'll post a revised version of this
patch !

Theres no file in /run/user/USERID if there was then you forgot to add the corresponding file context specification
there is however a sock file there: "bus"

/run/user/%{USERID/bus -s system_u:object_r:session_dbusd_user_runtime_t:s0
userdom_user_runtime_filetrans(session_bus_type, session_dbusd_user_runtime_t, sock_file)

The bus socket is not in the dbus-1 dir:

It is not a pid file its a userdom_user_runtime_file() or userdom_user_tmp_file()

I have fixed the above in the next version (v4)... Thanks for telling
me.

userdom_user_runtime_file() does not exist, however I can change it to
userdom_user_tmp_file().

Well, if there is a directory, then it is used for storing files...

I am fine with keeping the files pattern.

It does not harm and it might be useful in the future.

[refpolicy] [PATCH v4] dbus: let session bus daemon manage user runtime dirs

Pid is actually right, for now, as pids (in the refpolicy sense) are 
slowly turning into being a subset of runtime files.  Eventually the 
refpolicy pid file concept might go away.

logind needs to be able to purse XDG_RUNTIME_DIR and allowing logind to unlink all pid files would be too coarse IMHO

[refpolicy] [PATCH v5] dbus: let session bus daemon manage user runtime dirs

[Guido Trentalancia]

Let the session dbus process manage user runtime directories (with
its own file type).

This is the fifth version (v5) of the patch, thanks to Dominick
Grift for revising the previous versions and suggesting improvements,
although unfortunately this new version needs to revert one of the
suggested amendments because it was misleading.
