In red-parse-qxl.c add support for parsing QXLComposite into
SpiceComposite. In red-worker.c add support for marshalling
SpiceComposite onto the wire.

Graduality is irrelevant for A8 images, so instead of using RGB-ness
as a short-cut, add a new macro BITMAP_FMT_HAS_GRADUALITY() that
returns true for the existing RGB images, but false for A8.

After marshalling MSG_STREAM_CREATE, there is no need to ref and
unref stream->current before and after completing the sending of the
message (correspondingly). The referencing is unnecessary because all
the data that is required from the drawable (the clipping), is copied
during marshalling, and no field in the drawable is referenced (see
spice_marshall_msg_display_stream_create).
Moreover, the referencing was bugous:
While display_channel_hold_pipe_item and
display_channel_client_release_item_after_push referenced and
dereferenced, correspondingly, stream->current, stream->current might
have changed in between these calls, and then we ended up with one drawable
leaking, and one drawable released before its time has come (which
of course led to critical errors).

a SpiceMsgDisplayMonitorsConfig is sent on two occasions:
* as a result of a spice_qxl_monitors_config_async
* whenever a client connects and there is a previously set monitors
config
Sending the new message is protected by a new cap,
SPICE_DISPLAY_CAP_MONITORS_CONFIG
More elaborately:
spice_qxl_monitors_config_async receives a QXLPHYSICAL address of a
QXLMonitorsConfig struct and reads it, caching it in the RedWorker, and
sending it to all clients. Whenever a new client connects it receives
a SpiceMsgDisplayMonitorsConfig message as well.

Rules for replacing spice_printerr:
* if it's a client drop / agent drop, spice_error
* if it's important, spice_warning
* else, spice_info.
The fourth rule is spice_debug if it's going to fill up the log, but
nothing of the sort here.
Other things this patch does:
* changed reds_show_new_channel to reds_info_new_channel in an attempt to
advertise it doesn't always show anything, unless SPICE_DEBUG_LOG_LEVEL
>= SPICE_DEVUG_LOG_INFO (==3)
* removes two lines of whitespace.
* added "crashy" to multiple client warning (only warning introduced,
the rest are errors).

Specifically all those that the previous patch converted to spice_debug.
spice_debug contains very verbose stuff like update_area that drowns out
those relatively rare (client connect / disconnect generated) messages.
|
| |
|
|
|
|
|
| |
Replaced mostly with spice_debug, but spice_warning & spice_error as
well where appropriate.
|

The original definition is in spice.h

In addition, I also removed the no longer used wakeup callback

With SpiceCharDeviceState, the smartcard code now supports partial writes,
and storing data that is received from the client after the device is
stopped, instead of attempting to write it to the guest.

The lifetime of the channel is not necessarily correlated to the life
time of the device. In the next patch, we need to keep a reference
to SpiceCharDeviceWriteBuffer, which might be in use even if the
SpiceCharDeviceState is destroyed, but the channel is still connected.
The next patch keeps this reference inside SmartCardChannelClient.
This patch also removes the routine smartcard_readers_detach_all(rcc), which
is unnecessary since we don't support multiple readers; even when
we do support them, each channel client should be associated with only
one reader (i.e., we will have different channels for different
readers).
|
|
|
|
|
|
|
| |
This patch and the following one do not introduce tokening to the smartcard
channel. But this can be done easily later, by setting the appropriate
variables in SpiceCharDeviceState (after adding the appropriate protocol messages,
and implementing this in the client side).

With SpiceCharDeviceState, spicevmc now supports partial writes,
and storing data that is received from the client after the device is
stopped, instead of attempting to write it to the guest.

This patch and the following one do not introduce tokening to the
spicevmc channel. But this can be done easily later, by setting the appropriate

This is an intermediate patch. The next patch will actually
push the buffer to the device, instead of copying it.

This code is never called, it was relevant for seamless migration.
Most of the data that needs to be migrated was moved to
SpiceCharDeviceState. When we implement seamless migration,
we will have routines in char_device.c for migrating the relevant data.

- Allow sending tokens to a specific client.
- Do not ignore tokens that are sent from the client to the server.
The tokens support for multiple clients and for server side tokens
is still broken in reds. It will be fixed in following patches, when
the server-side agent code will use the SpiceCharDeviceState api.
Notice that ignoring the server-side tokens didn't introduce a problem
since both the client and the server set it to ~0.

SpiceCharDeviceState manages the (1) write-to-device queue
(2) wakeup and reading from the device (3) client tokens (4)
sending messages from the device to the client/s, considering the
available tokens.
SpiceCharDeviceState can be also stopped and started. When the device
is stopped, no reading or writing is done from/to the device. Messages
addressed from the client to the device are being queued.
Later, an api for stop/start will be added to spice.h and it should
be called from qemu.
This patch does not yet remove the wakeup callback from
SpiceCharDeviceState, but once all the char devices (agent/spicevmc/smartcard)
code will switch to the new implementation, SpiceCharDeviceState
will be moved to the c file and its reference to the wakeup callback will be removed.

Current bumped and age bumped for new intefaces only (no backward
incompatible changes).
New libtool version is 2.0.1, using --version-info instead of
--version-name. Doing the version change and --version-name to
--version-info change here to avoid changing the libtool version twice.
Added interfaces:
spice_server_set_name
spice_server_set_uuid
spice_server_set_listen_socket_fd
spice_server_is_server_mouse
New library name in linux:
libspice-server.so.1.1.0
Old:
libspice-server.so.1.0.2

The red_channel_client_event call to red_channel_client_receive might result
in a disconnected channel client. The following call to
red_channel_client_push may call to red_peer_handle_outgoing with a
disconnected socket.

Added ref count for RedChannel and RedChannelClient.
red_channel.c/red_peer_handle_incoming call to
handler->cb->handle_message might lead to the release of the channel
client, and the following call to handler->cb->release_msg_buf will be
a violation.
This bug can be produced by causing main_channel_handle_parsed
call red_client_destory, e.g., by some violation in
reds_on_main_agent_data that will result in a call to reds_disconnect.

red_wait_pipe_item_sent mistakingly returned without waiting for sending the given pipe item
when the channel wasn't blocked. As a result, we failed when we had to
destroy a surface (e.g., QXL_IO_DESTROY_ALL_SURFACES) and to release all
the drawables that are depended on it (by removing them or waiting they will be sent).
In addition, red_wait_pipe_item_sent increased and decreased the reference to the pipe item
using channel_cbs->hold_item, and channel_cbs->release_item. However,
these calls can be called only by red_channel, otherwise
display_channel_client_release_item_before_push is called twice and
leads to a double call to ring_remove(&dpi->base).
Instead ref/put_drawable_pipe_item should be called.
|
|
|
|
|
|
| |
The above routine was risky, since red_channel_client_init_send_data
can also be called with item==NULL. Thus, not all pipe items can be tracked.
The one call that was made for this routine was not necessary.

Fix a segfault caused by a call to __red_is_next_stream_frame made by
red_stream_maintenance, with a drawable that is not a DRAW_COPY one.
The segfault is a reault of __red_is_next_stream_frame accessing
red_drawable->u.copy.src_bitmap for a non DRAW_COPY drawable.

Before, we tested only higher frames, while wider frames would have
triggered a bug in mjpeg_encoder, when spice is linked with libjpeg and
not libjpeg-turbo.

Fix crashes when there are sized wider frames in the stream, and we are
linked with libjpeg.
