Eduardo Otubo f794573eab Adding support for libseccomp in configure and Makefile (v8)
Adding basic options to the configure script to use libseccomp or not.
The default is set to 'no'. If the flag --enable-libseccomp is used, the
script will check for its existence using pkg-config.

v1 -> v2:
 - As I removed all the code related to seccomp from vl.c, I created
   qemu-seccomp.[ch].
 - Also making the configure script to add the specific line to
   Makefile.obj in order to compile with appropriate support to seccomp.

v2 -> v3:
 - Removing the line from Makefile.obj and adding it to Makefile.objs.
 - Marking libseccomp default option to 'yes' in the configure script.

v3 -> v8:
 - fix configure probe if libseccomp isn't available (aliguori)

Luiz Capitulino 93b91c59db qemu-ga: switch to the new error format on the wire
IMPORTANT: this BREAKS qemu-ga compatibility for the error response.

Instead of returning something like:

{ "error": { "class": "InvalidParameterValue",
             "data": {"name": "mode", "expected": "halt|powerdown|reboot" } } }

qemu-ga now returns:

 { "error": { "class": "GenericError",
              "desc": "Parameter 'mode' expects halt|powerdown|reboot" } }

Notice that this is also a bug fix, as qemu-ga wasn't returning the
human message.

Michael Tokarev 3d9b49254f consolidate qemu_iovec_memset{,_skip}() into single function and use existing iov_memset()
This patch combines two functions into one, and replaces
the implementation with already existing iov_memset() from
iov.c.

The new prototype of qemu_iovec_memset():
  size_t qemu_iovec_memset(qiov, size_t offset, int fillc, size_t bytes)
It is different from former qemu_iovec_memset_skip(), and
I want to make other functions to be consistent with it
too: first how much to skip, second what, and 3rd how many
of it.  It also returns actual number of bytes filled in,
which may be less than the requested `bytes' if qiov is
smaller than offset+bytes, in the same way iov_memset()
does.

While at it, use utility function iov_memset() from
iov.h in posix-aio-compat.c, where qiov was used.

Lluís Vilanova 650ab98d1d tracetool: Rewrite infrastructure as python modules
The tracetool script is written in shell and has hit several portability
problems due to shell quirks or external tools across host platforms.
Additionally the amount of string processing and lack of real data
structures makes it tough to implement code generator backends for
tracers that are more complex.

This patch replaces the shell version of tracetool with a Python
version.  The new tracetool design is:

  scripts/tracetool.py - top-level script
  scripts/tracetool/backend/ - tracer backends live here (simple, ust)
  scripts/tracetool/format/  - output formats live here (.c, .h)

There is common code for trace-events definition parsing so that
backends can focus on generating code rather than parsing input.

Support for all existing backends (nop, stderr, simple, ust,
and dtrace) is added back in follow-up patches.

Anthony Liguori c7f0f3b1c8 qtest: add test framework
The idea behind qtest is pretty simple.  Instead of executing a CPU via TCG or
KVM, rely on an external process to send events to the device model that the CPU
would normally generate.

qtest presents itself as an accelerator.  In addition, a new option is added to
establish a qtest server (-qtest) that takes a character device.  This is what
allows the external process to send CPU events to the device model.

qtest uses a simple line based protocol to send the events.  Documentation of
that protocol is in qtest.c.

I considered reusing the monitor for this job.  Adding interrupts would be a bit
difficult.  In addition, logging would also be difficult.

qtest has extensive logging support.  All protocol commands are logged with
time stamps using a new command line option (-qtest-log).  Logging is important
since ultimately, this is a feature for debugging.

Michael S. Tsirkin 1dc324d20f shpc: standard hot plug controller
This adds support for SHPC interface, as defined by PCI Standard
Hot-Plug Controller and Subsystem Specification, Rev 1.0
http://www.pcisig.com/specifications/conventional/pci_hot_plug/SHPC_10

Only SHPC intergrated with a PCI-to-PCI bridge is supported,
SHPC integrated with a host bridge would need more work.

All main SHPC features are supported:
- MRL sensor
- Attention button
- Attention indicator
- Power indicator

Wake on hotplug and serr generation are stubbed out but unused
as we don't have interfaces to generate these events ATM.

One issue that isn't completely resolved is that qemu currently
expects an "eject" interface, which SHPC does not provide: it merely
removes the power to device and it's up to the user to remove the device
from slot. This patch works around that by ejecting the device
when power is removed and power LED goes off.

Michael Roth 7868e26e59 qemu-ga: add initial win32 support
This adds a win32 channel implementation that makes qemu-ga functional
on Windows using virtio-serial (unix-listen/isa-serial not currently
implemented). Unlike with the posix implementation, we do not use
GIOChannel for the following reasons:

 - glib calls stat() on an fd to check whether S_IFCHR is set, which is
   the case for virtio-serial on win32. Because of that, a one-time
   check to determine whether the channel is readable is done by making
   a call to PeekConsoleInput(), which reports the underlying handle is
   not a valid console handle, and thus we can never read from the
   channel.

 - if one goes as far as to "trick" glib into thinking it is a normal
   file descripter, the buffering is done in such a way that data
   written to the output stream will subsequently result in that same
   data being read back as if it were input, causing an error loop.
   furthermore, a forced flush of the channel only moves the data into a
   secondary buffer managed by glib, so there's no way to prevent output
   from getting read back as input.

The implementation here ties into the glib main loop by implementing a
custom GSource that continually submits asynchronous/overlapped I/O to
fill an GAChannel-managed read buffer, and tells glib to poll the
corresponding event handle for a completion whenever there is no
data/RPC in the read buffer to notify the main application about.

Michael Roth 42074a9d4d qemu-ga: separate out common commands from posix-specific ones
Many of the current RPC implementations are very much POSIX-specific
and require complete re-writes for Windows. There are however a small
set of core guest agent commands that are common to both, and other
commands such as guest-file-* which *may* be portable. So we introduce
commands.c for the latter, and will rename guest-agent-commands.c to
commands-posix.c in a future commit. Windows implementations will go in
commands-win32.c, eventually.

Michael Roth 125b310e1d qemu-ga: move channel/transport functionality into wrapper class
This is mostly in preparation for the win32 port, which won't use
GIO channels for reasons that will be made clearer later. Here the
GAChannel class is just a loose wrapper around GIOChannel
calls/callbacks, but we also roll in the logic/configuration for
various channel types and managing unix socket connections, which makes
the abstraction much more complete and further aids in the win32 port
since isa-serial/unix-listen will not be supported initially.

There's also a bit of refactoring in the main logic to consolidate the
exit paths so we can do common cleanup for things like pid files, which
weren't always cleaned up previously.
