In commit 44073d1b38 - client: improve WAN option description
one "," was missing at the end of the line. Since the next argument
was a string too, gcc silently concatenated them, and thanks to C++
polymorphic functions, the compiler didn't complain about the
missing argument, so it went unnoticed.
The effects are pretty bad though, since it prevents spicec from
running because it thinks command line parsing fails.
Both connect_secure() and connect_unsecure() call connect_to_peer().
Prior to this commit spicec.log reported all connections as unsecure,
as connect_secure() called connect_unsecure() to make the connection.
This fixes RH bug #653545
If you try to connect to a linux guest with WAN options, SPICE window opens up
and is blank - it then fails with vdagent timeout message. It should give a
warning that this is only applicable for windows guest and still connect to
guest.
It all starts in RedClient::handle_init
This function checks whether we have an agent or not, because if we have an
agent, there will be some kind of handshake to check both sides capabilities
before all the spice channels are created.
When there is no agent running, the startup process goes on with
SPICE_MSGC_MAIN_ATTACH_CHANNELS
When there is a windows agent running, VD_AGENT_ANNOUNCE_CAPABILITIES and
VD_AGENT_DISPLAY_CONFIG messages are sent to the agent, and when processing the
agent answer to the VD_AGENT_DISPLAY_CONFIG message,
SPICE_MSGC_MAIN_ATTACH_CHANNELS will be sent and the startup process will go
on.
However, when there is no agent running but --color-depth was used, handle_init
won't send the SPICE_MSGC_MAIN_ATTACH_CHANNELS message but will wait for the
agent handshake to proceed to its end, which won't happen, so it will timeout
waiting for agent answers.
Similarly, the linux agent handles VD_AGENT_ANNOUNCE_CAPABILITIES messages, but
it doesn't handle VD_AGENT_DISPLAY_CONFIG messages, so we'll never reach the
point where a SPICE_MSGC_MAIN_ATTACH_CHANNELS will be sent.
This commit fixes this in 2 places:
- unconditionnally send SPICE_MSGC_ATTACH_CHANNELS when no agent is running in
handle_init
- send SPICE_MSGC_MAIN_ATTACH_CHANNELS in
RedClient::on_agent_announce_capabilities if the agent doesn't have the
VD_AGENT_CAP_DISPLAY_CONFIG capability
This fixes RH bug #712938
The WAN options (--color-depth and --disable-effects) need
support from the guest agent to be working. Currently they are
only supported on Windows. While I don't want to explicitly
mention Windows in --help output, we can hint that it won't
work with all guests in --help. This fixes RH bug #712941
There is a double free in client/x11/platform.cpp.
In get_selection(), in the exit: case with ret_val == -1 and data != NULL,
*data_ret (which is returned to the caller) has already been
assigned "data", so it will be pointing to freed memory when "data" is
XFree'd'. Then in handle_selection_notify, get_selection_free is called on
this pointer, which causes a double free.
When the length of the read data = 0, set the returned value to NULL,
this way subsequent free attempts will be a noop.
Fixes RH bug #710461
These messages allow the guest to send the audio device volume to the
client. It uses an arbitrary scale of 16bits, which works good enough
for now.
Save VolumeState in {Playback,Record}State, so that we can send the
current volume on channel connection.
Note about future improvements:
- add exact dB support
- add client to guest volume change
Updated since v2:
- bumped record and playback interface minor version to allow
conditional compilation
Updated since v1:
- sync record volume on connection too
After shift+F11, both in Windows 7 and xp clients, WM_KEYUP events were missing for
SHIFT and F11. For F11 it was less important since unpress_all was preformed for all keys.
However, we perform sync for all the keyboard modifiers and the GetKeyboardState returns "down" for shift.
In windows7 client, we sometimes received afterwards a F11 KEYDOWN event repetition, and this caused SHIFT+F11 to be called again.
Not performing hiding of the windows while changing client resolutions, solved the problem of missing events, and I don't see any difference
in how spice looks while toggling to full screen.
Using GetAsyncKeyState, returns "UP" for shift in windows 7, and helps avoid performing shift+f11 again, if there is an F11 repetition
before we receive the KEYUP event for shift.
Enable image randomized base address, hindering some types of
security attacks by making it more difficult for an attacker
to predict target addresses.
-Release currently doesn't use precompiled headers at all
-Debug is broken since common/*.c files don't include common.h
-PCH can be enabled for all but specifically-chosen c-files
Video streams from Linux guests are oriented top-down, where gdi_canvas_put_image always
received display context for down-top oriented bitmap. I fixed create_bitmap
to consider the stream orientation.
Fixed since v1:
- don't include C code, rather use the common lib
- add missing spice_openssl_verify_free() call
- keep the extra-parsing of subject for error reporting
SW_CANVAS_NO_CHUNKS isn't used anywhere but in this file.
SW_CANVAS_CACHE is now defined directly in the files where it's
needed so we no longer need it in the .vcproj file.
When using config.h, it must be the very first include in all source
files since it contains #define that may change the compilation process
(eg libc structure layout changes when it's used to enable large file
support on 32 bit x86 archs). This commit adds it at the beginning
of all .c and .cpp files
spice client and spice server shares code from
common/{gdi,gl,sw}_canvas.[ch]. However, while most of the code is
shared, the server code wants a canvas compiled with
SW_CANVAS_IMAGE_CACHE defined while the client code wants a canvas
compiled with SW_CANVAS_CACHE.
The initial autotools refactoring didn't take that into account,
this is now fixed by this commit. After this commit, the canvas
files from common/ are no longer compiled as part of the
libspice-common.la convenience library. Instead, there are "proxy"
canvas source files in client/ and server/ which #include the
appropriate C files after defining the relevant #define for the
binary that is being built.
To prevent misuse of the canvas c files and headers in common/,
SPICE_CANVAS_INTERNAL must be set when including the canvas headers
from common/ or when building the c files from common/ otherwise
the build will error out.
spice Makefile.am setup is a bit confusing, with source file
names being listed several times in different Makefile.am
(generally, once in EXTRA_DIST and another time in another
Makefile.am in _SOURCES). The client binaries are built
by client/x11/Makefile.am, which means recursing into client,
then into x11 to finally build spicec. This Makefile.am is
also referencing files from common/ and client/, which is
a bit unusual with autotools.
This patch attempts to simplify the build process to get
something more usual from an autotools point of view.
The source from common/ are compiled into a libtool convenience
library, which the server and the client links against which avoids
referencing source files from common/ when building the server and
the client. The client is built in client/Makefile.am and directly
builds files from x11/ windows/ and gui/ if needed (without
recursing in these subdirectories).
This makes the build simpler to understand, and also makes it
possible to list source files once, which avoids potential
make distcheck breakage when adding new files.
There is a regression in this patch with respect to
sw_canvas/gl_canvas/gdi_canvas. They should be built with
different preprocessor #defines resulting in different behaviour
of the canvas for the client and the server. However, this is not
currently the case, both the client and the server will use the same
code for now (which probably means one of them is broken). This will
be fixed in a subsequent commit.
make distcheck passes, but compilation on windows using the
autotools build system hasn't been tested, which means it's likely
to be broken. It shouldn't be too hard ot fix it though, just let
me know of any issues with this.
client/ contains several .cpp file which only #include a .c file
of the same name. This is unusual and seems to only be done to
get C++ name mangling on the symbols defined in the C file.
Now that all headers files in common/ use extern "C", these
wrappers are no longer useful.
This fixes fdo bug #32896:
"Subject in certificates is stored in following format (values separated by
comma and space):
grep Subject: server-cert.pem | awk -F": " '{print $2}'
O=REDHAT, CN=10.34.58.2
While spicec expects that values in host subject are separated only by comma:
spicec --host-subject "O=REDHAT,CN=10.34.58.2"
"
In this case, ignoring spaces make it much easier to directly copy and paste
the subject line from certificates.
Commit 774e5bd36f changed
- dest->source.pixmap.x_image->data +
+ (uint8_t *)pixman_image_get_stride(dest->source.pixmap.pixman_image) +
The correct accessor to use is pixman_image_get_data. Thanks to gcc
4.6 for warning about a "different size" int to pointer conversion.
The server Makefile.am rules for marshallers generation are
prefixed with AM_V_SILENT to integrate nicely with automake silent
rules. The same AM_V_SILENT prefix isn't used in client/Makefile.am
resulting in verbose output even when automake silent mode is
enabled. This commit removes this verbosity.
Although ICCCM 2.2. Responsibilities of the Selection Owner:
http://tronche.com/gui/x/icccm/sec-2.html#s-2.2
Clearly states (about selection notify events):
The owner should set the specified selection, target, time, and property
arguments to the values received in the SelectionRequest event.
xsel sets the selection notify event target member to the incr atom when it
is going to send the clipboard data incremental, rather then setting it to
the UTF8_STRING atom (which was the target of the SelectionRequest).
Work around this (esp as it is likely other programs may get this wrong too)
and accept the incr atom as a valid target in a selection notify event.
This fixes Alon's test with running:
python -c "print list(range(1000))" | xsel -i -b
on the client.
Some apps (bad xsel, bad!) send invalid Atoms in their TARGETS property,
causing spicec to exit because of an XError. This patch makes spicec survive
this scenario.
For more info on the xsel bug, see:

When OpenGL is enabled, build fails in DisplayChannel::create_surface
because Canvas *canvas is declared twice. Remove the first
declaration to fix compilation.
In some cases rhev-m changes the hotkey for releasing the mouse grab
to ctrl + alt. This makes it impossible to send ctrl + alt + other-key
to the guest, even when using sticky alt.
What happens is:
-press alt until sticky alt activates
-release alt (but recorded state stays pressed due to sticky alt)
-press ctrl
-hotkey code sees ctrl+alt pressed, releases mouse grab
-mouse grab release code does an unpress all -> end of sticky state.
This patch makes it possible to atleast send ctrl + alt + del (or other key)
using sticky alt. Note: even with this patch it is still a bad idea to
use ctrl + alt as hotkey combi.
using updated windows libraries:

-remove IgnoreDefaultLibraryNames="MSVCRT.lib", since pixman is now compiled
using MT threading model similar to other libraries. It used to be mistakenly
compiled with MD.
-downgrade freetype lib to 2.3.11-7, which is the one used/tested with
CEGUI 0.6.2
-pthread lib patched (InterlockedCompareExchange), so x64 client will no
longer crash on SelectClipRgn, BitBlt etc.
This avoids us trying to restore the original resolution when we're fullscreen
and an X error happens. As restoring fullscreen is a bad idea then as this
involves making more X calls, which can get us stuck (in side an XLockDisplay
call for example).
instead of ..\..\..\spice-protocol. Relative path to another git tree is a bit
ugly, since it requires spice-protocol to be in a specific location.
SPICE_PROTOCOL_DIR should also be used in windows qxl and vdagent instead of
SPICE_COMMON_DIR, which is an old and confusing name, due to the common
directory in spice git repo.
uses VSC_Error with code==VSC_SUCCESS instead. This means that the VSC_Error
message is overloaded. Instead of the other option of adding a message id,
since the connection is TCP so no messages may be dropped or reordered, by
having each message followed by a response there is no ambiguity. Still
this commit adds a queue for messages that we only have one of which outstanding
at a time, i.e. send, wait for response, send the next, etc. This further
simplifies the logic, while not adding much overhead since only when spicec
starts up it has a situation where it needs to send two events (ReaderAdd
and ATR for Card Insert).
