d1620d9a32 dom0/qrexec: kill child process on connect timeout 
Sometimes vchan can not detect dead target domain so kill it explicit to not
leave a mess.

46fd664ba3 dom0/qrexec: implement default user handling in qrexec_daemon 
This will simplify using qrexec from utilities which doen't load qubes.xml
normally (like qrexec_policy, gui daemon).

3bce6047b5 dom0/qrexec: properly process data after client terminated one way of transfer 
Instead of removing client from list at EPIPE error from write, assume that
client does not wish read future data, but still can write something.

f79101d114 dom0/qrexec: fix the case when client disconnected while sending cmdline 
Previously there was not cleaned up entry in clients table. Not critical, as
will be reset to known state at new client connect, but still fix it.

b4f28152b8 qrexec: CONNECT_EXISTING command handling in daemon and client 2011-07-04 20:55:25 +02:00
Rafal Wojtczuk
c05b26763a qrexec: new communication scheme, agent<->server part 
1) Instead of a set of predefined commands, we send MSG_AGENT_TO_SERVER_TRIGGER_CONNECT_EXISTING msg with a parameter (e.g. "org.qubes-os.vm.Filecopy")
defining required action
2) qrexec_daemon just forks qrexec_policy, that will take care of actually
allowing and executing required action
3) after MSG_AGENT_TO_SERVER_TRIGGER_CONNECT_EXISTING, qrexec_agent does not
execute a command - it justs uses already established file descriptors to
send data to/from. Thus, there is no need to use ~/.xxxxxspool - a command line
tool can have direct access to remote fds.

1d24ef9d1a qrexec: when forgetting about a client/process, flush buffered data 
We need to spawn a child to take care of buffered data flushing, if there
is any. Expensive, but should be needed rarely.

and DoS dom0.

f1a7df6e95 Implemented mechanism to trigger predefined execution in dom0. 
Processes in AppVM can ask qrexec-agent to send a
MSG_AGENT_TO_SERVER_TRIGGER_EXEC message to qrexec-daemon.
The latter will execute predefined program. It is useful for
the purpose of file copy; the predefined program will create
a connected qfile-daemon<->qfile-agent pair.
