* server: introduce dispatcherAlon Levy2011-11-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | used for main_dispatcher only in this patch. Dispatcher is meant to be used for Main<->any low frequency messages. It's interface is meant to include the red_dispatcher usage: fixed size messages per message type some messages require an ack Some methods are added to be used by RedDispatcher later: dispatcher_handle_read - to be called directly by RedDispatcher epoll based loop dispatcher_set_opaque - to be set from red_worker pthread dispatcher_init - allow NULL core as used by red_worker Read and Write behavior: Sender: blocking write, blocking read for ack (if any). Reader: poll for any data, if such then blocking read for a message_type and following message. repeat until poll returns with no pending data to read. FDO Bugzilla: 42463
* [0.8 branch] server: add main_dispatcherAlon Levy2011-10-311-0/+2
| | | | | | | | | | | | | | | | | | | | | | | add main_dispatcher, a message passing mechanism for sending messages to the main thread. The main thread is the thread that implements SpiceCoreInterface, which is assumed to be a single thread. Similar to the async operation of red_worker, a socket pair is created and used to pass messages. The messages are a fixed size to ease parsing. A single message is defined to pass a channel_event. RHBZ: 746950 FDBZ: 41858 This patch is 0.8 branch only, for the master branch there should be a better approach to share code with red_dispatcher and ready the way for later adding more threads. cherry-pick from 0.8 80caf07e09efe14c67f89a3c01501a6a39681167 Conflicts: server/reds.c
* Rename usbredir channel code to spicevmcHans de Goede2011-08-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While discussing various things with Alon in Vancouver, it came up that having a channel which simply passes through data coming out of a qemu chardev frontend unmodified, like the usbredir channel does, can be used for a lot of other cases too. To facilitate this the usbredir channel code will be turned into a generic spicevmc channel, which is just a passthrough to the client, from the spicevmc chardev. This patch renames usbredir.c to spicevmc.c and changes the prefix of all functions / structs to match. This should make clear that the code is not usbredir specific. Some examples of why having a generic spicevmc pass through is good: 1) We could add a monitor channel, allowing access to the qemu monitor from the spice client, since the monitor is a chardev frontend we could re-use the generic spicevmc channel server code, so all that is needed to add this (server side) would be reserving a new channel id for this. 2) We could allow users to come up with new channels of their own, without requiring qemu or server modification. The idea is to allow doing something like this on the qemu startup cmdline: -chardev spicevmc,name=generic,channelid=128 To ensure these new "generic" channels cannot conflict with newly added official types, they must start at the SPICE_CHANNEL_USER_DEFINED_START value (128). These new user defined channels could then either be used with a special modified client, with client plugins (if we add support for those), or by exporting them on the client side for use by an external ap, see below. 3) We could also add support to the client to make user-defined channels end in a unix socket / pipe, allowing handling of the data by an external app, we could for example have a new spice client cmdline argument like this: --custom-channel unixsocket=/tmp/mysocket,channelid=128 This would allow for something like: $random app on guest -> virtio-serial -> spicevmc chardev -> -> spicevmc channel -> unix socket -> $random app on client 4) On hind sight this could also have been used for the smartcard stuff, with a 1 channel / reader model, rather then the current multiplexing code where we've our own multiplexing protocol wrapper over the libcacard smartcard protocol.

* server: add symbol versioning to the spice server shared library.Gerd Hoffmann2011-07-191-0/+1
| | | | | | | | | | This patch adds symbol versions to the spice server library. Each symbol which is exported by libspice-server gets tagged with the (stable) version where it appeared first. This way the linker and rpm are able to figure which version of the spice-server libary is required by a particular qemu binary/package. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

* autotools: correctly build canvas-related codeChristophe Fergeau2011-05-031-1/+9
| | | | | | | | | | | | | | | | | | | | | 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.
* autotools: refactor the whole build machineryChristophe Fergeau2011-05-031-81/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Store SpicePath segment count rather than sizeAlexander Larsson2010-06-301-1/+1
| | | | | | | | | | | | | | | | | | | Internally and in the network protocol (for the new version) we now store the actual number of segments rather than the size of the full segments array in bytes. This change consists of multiple changes to handle this: * Make the qxl parser calculate num_segments * Make the canvas stroke code handle the new SpicePath layout. * Fix up is_equal_path in red_worker.c for the new layout * replace multiple calls to spice_marshall_PathSegment with a single spice_marshall_Path call * Make the byte_size() array size handling do the conversion from network size to number of elements when marshalling/demarshalling. * Update the current spice protocol to send the segment count rather than the size * Update the old spice protocol to use the new byte_size functionallity to calculate the size sent and the number of elements recieved

* New memory allocators that exit on OOM and handle multiplication overflowAlexander Larsson2010-03-111-0/+1
| | | | | | | | | Every place that does a regular malloc/calloc and aborts on failure should use spice_malloc/spice_mallo0 instead, which is leaner and cleaner. Allocations of dynamically sized arrays can use g_malloc_n or g_new etc which correctly handle multiplication overflow if some of the arguments are not trusted.
