From: Leonid Bloch <leonid@daynix.com>

Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered.

Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.

Previously, if building out-of-tree, the MSI build would fail since
it wasn't able to find the needed files.

Currently we need to examine config-host.mak to determine whether
options/probes for MSI package generation had desired result. Report
this more prominently in ./configure summary as we do with other
guest agent configure options.

The option parsing is going to be moved to a separate function,
use exit() consistently.

In order to avoid any confusion, let's allocate new strings when
splitting.

'path' is already a global function, rename the variable since it's
going to be in global scope in a later patch.

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Following patch will return allocated strings, so we must correctly
initialize alloc & free them. The nice side effect is that we no longer
have to check for "fixed_state_dir" to call ga_install_service() with a
NULL state dir. The default values are set after parsing the command
line options.

more allocations.

Learn to configure the agent with a system configuration.

This may simplify command-line handling, especially when the blacklist
is long.

Among the other benefits, this may standardize the configuration of an
init service (instead of distro-specific init keys/files)

+@example
+@c man begin SYNOPSIS
+usage: qemu-ga [OPTIONS]
+@c man end
+@end example
+
+@c man begin DESCRIPTION
+
+The QEMU Guest Agent is a daemon intended to be run within virtual
+machines. It allows the hypervisor host to perform various operations
+in the guest, such as:
+
+@itemize
+@item
+get information from the guest
+@item
+set the guest's system time
+@item
+read/write a file
+@item
+sync and freeze the filesystems
+@item
+suspend the guest
+@item
+reconfigure guest local processors
+@item
+set user's password
+@item
+...
+@end itemize
+
+qemu-ga will read a system configuration file on startup (located at
+q@file{/etc/qemu/qemu-ga.conf} by default), then parse remaining
+configuration options on the command line. For the same key, the last
+option wins, but the lists accumulate (see below for configuration
+file format).
+
+@c man end
+
+@c man begin OPTIONS
+@table @option
+@item -m, --method=@var{method}
+  Transport method: one of @samp{unix-listen}, @samp{virtio-serial}, or
+  @samp{isa-serial} (@samp{virtio-serial} is the default).
+
+@item -p, --path=@var{path}
+  Device/socket path (the default for virtio-serial is
+  @samp{/dev/virtio-ports/org.qemu.guest_agent.0},
+  the default for isa-serial is @samp{/dev/ttyS0})
+
+@item -l, --logfile=@var{path}
+  Set log file path (default is stderr).
+
+@item -f, --pidfile=@var{path}
+  Specify pid file (default is @samp{/var/run/qemu-ga.pid}).
+
+@item -F, --fsfreeze-hook=@var{path}
+  Enable fsfreeze hook. Accepts an optional argument that specifies
+  script to run on freeze/thaw. Script will be called with
+  'freeze'/'thaw' arguments accordingly (default is
+  @samp{/etc/qemu/fsfreeze-hook}). If using -F with an argument, do
+  not follow -F with a space (for example:
+  @samp{-F/var/run/fsfreezehook.sh}).
+
+@item -t, --statedir=@var{path}
+  Specify the directory to store state information (absolute paths only,
+  default is @samp{/var/run}).
+
+@item -v, --verbose
+  Log extra debugging information.
+
+@item -V, --version
+  Print version information and exit.
+
+@item -d, --daemon
+  Daemonize after startup (detach from terminal).
+
+@item -b, --blacklist=@var{list}
+  Comma-separated list of RPCs to disable (no spaces, @samp{?} to list
+  available RPCs).
+
+@item -D, --dump-conf
+  Dump the configuration in a format compatible with @file{qemu-ga.conf}
+  and exit.
+
+@item -h, --help
+  Display this help and exit.
+@end table
+
+@c man end
+
+@c man begin FILES
+
+The syntax of the @file{qemu-ga.conf} configuration file follows the
+Desktop Entry Specification, here is a quick summary: it consists of
+groups of key-value pairs, interspersed with comments.
+
+@example
+# qemu-ga configuration sample
+[general]
+daemonize = 0
+pidfile = /var/run/qemu-ga.pid
+verbose = 0
+method = virtio-serial
+path = /dev/virtio-ports/org.qemu.guest_agent.0
+statedir = /var/run
+@end example
+
+The list of keys follows the command line options:
+@table @option
+@item daemon= boolean
+@item method= string
+@item path= string
+@item logfile= string
+@item pidfile= string
+@item fsfreeze-hook= string
+@item statedir= string
+@item verbose= boolean

Use NetUserSetInfo() to set the user password.

This function is notoriously known to be problematic for users with EFS
encrypted files. But the alternative, NetUserChangePassword() requires
the old password. Nevertheless, The EFS file should be recovered by
changing back to the old password.

From: Michael Roth @ 2015-09-01 18:39 UTC (permalink / raw)
  To: qemu-devel; +Cc: peter.maydell, Michael Roth

MSI probe assumes that qemu-ga support has been probed already, but in
cases where --enable-guest-agent/--disable-guest-agent have not been
passed to configure, qemu-ga support may end up getting enabled later,
as is the case with w32 builds. This leads to MSI probe prematurely
reporting error due to lack of qemu-ga support.

Fix this by moving MSI installer probe after the final qga probes.

Currently, if we don't explicitly disable support for MSI installer
via --disable-guest-agent-msi, the configure variable that tracks
the flag, 'guest_agent_msi', never gets set unless one of the probes
fails. Subsequent code then treats this unset value the same as if it
were a "yes" value (via != "no" style checks).

Instead, set the default "yes" value explicitly after the probes, then
make subsequent code expect the values to be set.

This makes it easier to report on whether or not MSI support was
enabled via probe by looking at the ./configure summary.

Currently VSS dll/tlb files for use in w32 builds are only built as a
result of having been added to the general 'tools' target alongside
qemu-ga. This is fine for default make target, but if we build
qemu-ga directly via `make qemu-ga.exe`, the VSS files are not
created.

Fix this by moving the VSS dependencies to qemu-ga.exe directly.
With this move we can move the VSS files back out of 'tools',
and drop the extra handling from MSI target in Makefile.

Now we can build qemu-ga MSI package with:
  ./configure ...
  make qemu-ga.exe
  make msi

or simply:
  ./configure ...
  make msi

and no longer need to do a full build beforehand.

'msi' target reports error if we attempt to use it when QEMU hasn't
been ./configure'd to enable it. The parenthesis cause an interpreter
error if we don't enclose the error in quotes.
