Richard Jones [Mon, 21 Sep 2009 14:27:20 +0000 (15:27 +0100)]
Implement "null vmchannel" - no vmchannel needed!

This commit removes the requirement for vmchannel, although retaining
support for it.

In this configuration, known as "null vmchannel", the library
listens on a random loopback port.  It passes the number of this
port to the appliance (guestfs_vmchannel=tcp:10.0.2.2:12345), and
the daemon then connects back.  The library, instead of connecting,
listens and accepts the connection during guestfs_launch.

QEMU SLIRP (user mode networking) is still required to make this
work: SLIRP forwards the TCP connection transparently (instead of
explicitly as with guestfwd) to 127.0.0.1:<port>

There is a window in which any other local process on the machine
could see the port number in the qemu command line and try to
connect to it.  This would be a devastating security hole, because
any local process could pretend to be the daemon and feed back
malicious replies to our remote procedure calls.  To prevent this,
we check the UID of the other side of the TCP connection.  If
the UID is different from the library's EUID, then we reject the
connection.  To do this we have to parse /proc/net/tcp.  (On Solaris
we could use getsockopt (SO_PEERCRED), but this doesn't work on
Linux TCP sockets).

Other vmchannel(s) are still supported.  This is important, because
we can't in general be sure the qemu will always support SLIRP.
In particular, in recent versions of qemu it is possible to compile
out SLIRP.

This reimplements parts of commit da0a4f8d1f6ddd302ceba028d87c6e009589e503
in a different, but compatible way.

We pass guestfs_vmchannel=tcp:<ip>:<port> on the command line.  This
is intended to be used as follows (now and in future versions):

  tcp:10.0.2.4:6666    for guestfwd vmchannel
  tcp:10.0.2.2:<port>  for future "no vmchannel" implementation
  /dev/vcon4           for future virtio-console vmchannel*

It also accepts the old-style guestfs=10.0.2.4:6666 parameter which
is sent by older libraries, and turns this transparently into the
correct format above.

If no guestfs_vmchannel is passed, then this defaults to the guestfwd
vmchannel which older libraries would expect.

* Maybe this last one should be dev:/dev/vcon4 or file:/dev/vcon4, but
we don't need to decide that now.

Remove main loop.

This commit removes the external main loop, which never worked
and caused a number of bugs.  Requests are now done synchronously,
and if the user wants to have requests issued in the background
or to have a responsive GUI, then they'll just have to use threads.

The big change is to push all reads and writes through two
functions called send_to_daemon (for writes) and recv_from_daemon
(for reads) which operate synchronously.  These functions
read/write whole messages, and also handle checking for EOF
(ie. daemon died) and asynchronous log message events from
qemu (eg. from debug / dmesg printed by the guest).  A more
complete description of how these work can be found in the code.

This code passes a complete run of the tests.

Bugs believed to be fixed by this commit:

guestfish: Enable grouping in string lists

This change adds the ability to group entries in a string list with single
quotes. So the string:
  "'foo bar'"
becomes 1 token rather than 2. Consequently single quotes must now be escaped:
  "\'"
resolves to a literal single quote.

Incidentally, this change also alters another, probably unintentional behaviour
of the previous implementation, in that tokens are separated by any amount of
whitespace rather than a single whitespace character. I.e.:
  "a  b"
resolves to:
  'a' 'b'
rather than:
  'a' '' 'b'
That last syntax can be used if an empty argument is still desired. Whitespace
is now also defined to include tabs.

parse_string_list can also now fail if it contains an unmatched open quote.

Non-daemon actions indirect through generated code.

int
guestfs_set_verbose (guestfs_h *g, int v)
{
  g->verbose = !!v;
  return 0;

This changes these actions so they go indirectly via
some generated code, eg:

/* Generated */
int guestfs_set_verbose (guestfs_h *g,
int verbose)

guestfish: Redirect stdout when executing remote commands

guestfish --listen necessarily redirects its stdout to /dev/null so as not to
interfere with eval. The remote protocol doesn't contain any other provision for
collecting stdout for the caller, so executing guestfish --remote will never

This patch fixes that by forwarding the caller's STDOUT to the listener over the
unix socket connection. The listener redirects its STDOUT to the caller's STDOUT
for the duration of the command, then closes it again.
