Commit 8c89485 added a call to g_clear_pointer().
|
|
Don't set default ca-file path if the file doesn't exists.
|
|
If no CA path is given, a default one is set. Use g_build_filename() to
set a more portable and valid default path.
|
|
The list of channels returned by spice_session_get_channels()
must be freed after use.
|
|
When destroying the primary surface, we need to signal it, since
listeners might be referencing the data pointer. Currently, this only
happens during channel finalize().
This could help with rhbz#1082555.
|
|
The channel state is not synchronous.
It may happen that we want to set and unset quickly a modifier, but the
guest modifier state hasn't been updated yet, and will still be seen as
unset, preventing the last unset change.

GDK_IS_X11_DISPLAY is not available on gtk+ 2.x, but it already has a
fallback definition in gtk-compat.h
|
|
There are gtk+ version checks in several source files to add
compatibility implementations of gtk3 functions not available
in gtk2. This commit gathers all of them in a gtk-compat.h header,
similar to what is done for glib-compat.h
|
|
This was introduced in glib 2.32 and the webdav channel uses it.
|
|
This fixes this warning/error:
channel-webdav.c: In function 'demux_to_client':
channel-webdav.c:318:5: error: format '%ld' expects argument of type 'long
int', but argument 5 has type 'gssize' [-Werror=format=]
CHANNEL_DEBUG(self, "pushing %ld to client %p", size, client);

Spice-GTK provides SPICE-specific command line options. This man page
describes these options as well as the format of SPICE URIs.
|
|
Connect to the GdkKeymap::state-changed signal to detect when the client
keyboard modifiers have changed. This keeps the client and the guest in sync
even when the SpiceDisplay widget isn't focused. New values are only sent down
to the guest if the new value is different than the current value.
|
|
In certain circumstances, the keyboard modifiers get out-of-sync between the
guest and the client. This is easy to reproduce with the following steps:
- launch virt-viewer with a guest that is not running
- start the guest
- while guest is booting, enable CAPS LOCK on the client
- after guest finishes booting, it will set its modifiers to a default value
(e.g. numlock on, capslock off)
- now capslock is OFF in the guest, but ON in the client
- toggle caps lock
- now capslock is ON in the guest, but OFF in the client
This moves the responsibility for synchronizing client and guest modifiers into
SpiceGtkSession. It can't be handled easily within the SpiceDisplay widget since
there can be multiple display widgets for each inputs channel.
A new function (spice_gtk_session_sync_keyboard_modifiers()) was added so that
synchronization can be triggered manually if desired. But it also registers a
signal handler for the InputsChannel::inputs-modifiers signal to detect when the
guest has changed its modifiers. The signal handler simply overrides the guests
modifiers and sets them back to the value from the client.

Now that upstream provides a stable/versioned API, it will be
easier to deal with than with submodules.

configure.ac tries to assign a default value of 0 to the micro version if it's
empty, but the shell variable assignemnt doesn't work because there's whitespace
around the '=' sign.
This results in SPICE_GTK_MICRO_VERSION being defined to (), which causes a
compilation failure in files that include it.

A client setting this capability indicates to the server that it's able
to handle SASL authentication, and it also indicates that if SASL is
to be used for authentication, then it won't expect a valid 'pub_key' field
in SpiceLinkReply.
The reason for making guarantees about not looking at the pub_key field is
that its presence and size is hardcoded in the protocol, but in some
hardened setups (using fips mode), generating a RSA 1024 bit key as
expected is forbidden and fails. With this new capability, the server
knows the client will be able to handle SASL if needed, and can skip
the generation of the key altogether. This means that on the setups
described above, SASL authentication has to be used.

Address Alon's review from

Allow to specify the shared directory from the command line, or at
runtime via properties. (still default to xdg public share, if none
specified)

See spice-common for protocol details. phodav, a webdav server library,
is imported thanks to a submodule, until this project has a stable API
and releases.
The webdav channel is reponsible for handling port events and
multiplexing the request streams. Extra care has been made to avoid
blocking and to enable some fairness between concurrent streams, however
this has been particularly tricky and is likely to have some issues
left.
The webdav server is run in a seperate thread, using libsoup. The client
communication is done via a local tcp socket, but protected to only
accept local connection and with a pretty strong password.
The home directory is exported for the remote to browse, which seems to
be a sensible default atm.

When building with mingw64, several warnings about using the wrong format
specifier for gssize/gsize occur similar to:
win-usb-dev.c: In function 'g_udev_client_list_devices':
win-usb-dev.c:145:21: error: format '%i' expects argument of type 'int', but argument 7 has type 'gssize' [-Werror=format=]
name, errstr, rc);
This commit makes use of the G_GSIZE_FORMAT/G_GSSIZE_FORMAT macros provided
by glib to silence these warnings.
I've checked that this does not introduce new warnings on linux and mingw32
builds.

Fix screenshot of secondary displays, with an area position != (0,0).
This has never been working correctly since the surface display "area"
was introducted in:

While looking at the SASL code, I noticed some memory leaks in error paths.
This commit adds a cleanup: block to free some of the memory dynamically
allocated in that function, and remove the corresponding g_free() from
the regular code flow. This should ensure that both the regular path
and the error paths free the same memory.
This fixes at least this 'mechlist' leak which I got during regular SASL

This is recommended by autoconf documentation
http://nondot.org/sabre/Mirrored/autoconf-2.12/autoconf_3.html#SEC15
and some #defines in config.h can change what happens in system headers,
so config.h has to be included first.
The only file which does not get this treatment is
gtk/spice-client-gtk-module.c as this breaks the build on gtk+2:

After e124a3b2e which added the SPICE_GTK_CHECK_VERSION macro, a non-fatal
'./configure: line 15251: x24: command not found' appears in configure
output. This is because [ ] is not interpreted as the 'test' command by
autoconf, but is rather used as a way to quote configure.ac content.
This commit replaces the use of [] with a more typical AS_IF.
|

wocky-http-proxy.c and vmcstream.c make use of functions that were
not available in glib 2.26 so we need fallback for them through
glib-compat.h or spice-gtk won't build with older glibs.

Since 1fcaaa15f8aca362f9e6afc87fb43cfbccf6ff62, display_surface is
allocated using gslice. However MSG_DISPLAY_MODE handler didn't allocate
using GSlice. This can eventually lead to a crash when freeing, such as:
Thread no. 1 (6 frames)
#2 g_slice_free1 at gslice.c:1097
#3 iter_remove_or_steal at ghash.c:787
#4 clear_surfaces at /lib64/libspice-client-glib-2.0.so.8

Learn to return the currently configured proxy, to allow
client to tweak parameters, such as username and password.
|
|
Add a function to retrieve the last GError from a channel, this may be
useful to provide additional error details to the client.
|
|
Generalize a little bit SpiceProxy to allow easy URI manipulation by
clients.
|
|
|
|
Get rid of a superflous g_socket_condition_check().
|
|
Although reusing BIO_new_socket() once again is a hack, it seems
to be the easiest way... The proper solution is certainly to start
using GTls instead, but that will require a glib 2.28 dep bump.
|
|
This way, the call might eventually support more proxy and
authentication.
|
|
This will require glib 2.28 for GTls support, atm
|
|
|
|
Or Squid will fail with:
WARNING: Unsupported or unconfigured/inactive proxy-auth scheme
