2011-03-22fix vnc regressionWen Congyang1-2/+6
This patch fix the following regression: 1. we should use bitmap_set() and bitmap_clear() to replace vnc_set_bits(). Signed-off-by: Wen Congyang <wency@cn.fujitsu.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-03-21change all rt_clock references to use millisecond resolution accessorsPaolo Bonzini1-5/+5
This was done with: sed -i '/get_clock\>.*rt_clock/s/get_clock\>/get_clock_ms/' \ $(git grep -l 'get_clock\>.*rt_clock' ) sed -i '/new_timer\>.*rt_clock/s/new_timer\>/new_timer_ms/' \ $(git grep -l 'new_timer\>.*rt_clock' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2011-03-10vnc: Fix stack corruption and other bitmap related bugsStefan Weil1-5/+1
Commit bc2429b9174ac2d3c56b7fd35884b0d89ec7fb02 introduced a severe bug (stack corruption). bitmap_clear was called with a wrong argument which caused out-of-bound writes to the local variable width_mask. This bug was detected with QEMU running on windows. It also occurs with wine: *** stack smashing detected ***: terminated wine: Unhandled illegal instruction at address 0x6115c7 (thread 0009), starting debugger... The bug is not windows specific! Instead of fixing the wrong parameter value, bitmap_clear(), bitmap_set and width_mask were removed, and bitmap_intersect() was replaced by !bitmap_empty(). The new operation is much shorter and equivalent to the old operations. The declarations of the dirty bitmaps in vnc.h were also wrong for 64 bit hosts because of a rounding effect: for these hosts, VNC_MAX_WIDTH is no longer a multiple of (16 * BITS_PER_LONG), so the rounded value of VNC_DIRTY_WORDS was too small. Fix both declarations by using the macro which is designed for this purpose.

2011-02-23vnc: Fix fatal crash with vnc reverse modeStefan Weil1-0/+1
Reverse mode is unusable: qemu -vnc localhost:5500,reverse crashes in vnc_refresh_server_surface because some pointers are NULL. Fix this by calling vnc_dpy_resize (which initializes these pointers) before calling vnc_refresh.

2011-02-23vnc: fix lossy rect refreshingCorentin Chary1-4/+8
The for loop in send_lossy_rect was totally wrong, and we can't call vnc_set_bits() because it does not really do what it should. Use vnc_set_bit() directly instead. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-02-23vnc: refresh lossy rect after a given timeoutCorentin Chary1-3/+64
If an adaptive encoding has choosen to send a lossy update based on the result of vnc_update_freq(), then it should advertise it with vnc_sent_lossy_rect(). This will allow to automatically refresh this rect once it's static again. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-02-23vnc: add a way to get the update frequency for a given regionCorentin Chary1-0/+101
This patch compute the update frequency (in Hz) for each 64x64 rects. Any adaptive encoding can get this value using vnc_update_freq(), and switch to a lossy encoding if the value is too high. The frequency is pre-calculated every 500ms, based on the last 10 updates per 64x64 rect. If a 64x64 rect was not updated in the last 2 second, then the frequency became 0, and all the stored timestamp are reseted.

2011-02-23vnc: don't set the quality if lossy encoding are disabledCorentin Chary1-1/+3

2011-02-01vnc: Fix password expiration through 'change vnc ""' (v2)Anthony Liguori1-10/+27
commit 52c18be9e99dabe295321153fda7fce9f76647ac introduced a regression in the change vnc password command that changed the behavior of setting the VNC password to an empty string from disabling login to disabling authentication. This commit refactors the code to eliminate this overloaded semantics in vnc_display_password and instead introduces the vnc_display_disable_login. The monitor implementation then determines the behavior of an empty or missing string. Recently, a set_password command was added that allows both the Spice and VNC password to be set. This command has not shown up in a release yet so the behavior is not yet defined. This patch proposes that an empty password be treated as an empty password with no special handling. For specifically disabling login, I believe a new command should be introduced instead of overloading semantics. I'm not sure how Spice handles this but I would recommend that we have Spice and VNC have consistent semantics here for the 0.14.0 release. Reported-by: Neil Wilson <neil@aldur.co.uk> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - Add a proper return to make sure that login is really disabled instead of relying on the VNC server to treat empty passwords specially
2011-01-24vnc: fix numlock+capslock trackingGerd Hoffmann1-2/+2
This patch makes the numlock+capslock tracking logic only look at keydown events. Without this patch the vnc server will insert bogous capslock keypress in case it sees the following key sequence: shift down --- 'A' down --- shift up --- 'A' up ^ here It doesn't hurt with a PS/2 keyboard, but it disturbs the USB Keyboard. And with the key event queue just added to the usb keyboard the guest will actually notice. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09vnc: support password expireGerd Hoffmann1-0/+14

2010-12-09vnc: auth reject cleanupGerd Hoffmann1-17/+13

2010-07-26vnc: threaded VNC serverCorentin Chary1-24/+120
Implement a threaded VNC server using the producer-consumer model. The main thread will push encoding jobs (a list a rectangles to update) in a queue, and the VNC worker thread will consume that queue and send framebuffer updates to the output buffer. The threaded VNC server can be enabled with ./configure --enable-vnc-thread. If you don't want it, just use ./configure --disable-vnc-thread and a syncrhonous queue of job will be used (which as exactly the same behavior as the old queue). If you disable the VNC thread, all thread related code will not be built and there will be no overhead.

2010-07-26vnc: tight add PNG encodingCorentin Chary1-4/+7
Introduce a new encoding: VNC_ENCODING_TIGHT_PNG [1] (-269) with a new tight filter VNC_TIGHT_PNG (0x0A). When the client tells it supports the Tight PNG encoding, the server will use tight, but will always send encoding pixels using PNG instead of zlib. If the client also told it support JPEG, then the server can send JPEG, because PNG will only be used in the cases zlib was used in normal tight. This encoding was introduced to speed up HTML5 based VNC clients like noVNC [2], but can also be used on devices like iPhone where PNG can be rendered in hardware.
