2013-01-26make_device_config.sh: Fix target path in generated dependency fileAndreas Färber1-1/+1
config-devices.mak.d is included from Makefile.target, i.e. from inside the *-softmmu/ directory. It included the directory path, so never applied to the actual ./config-devices.mak. Symptoms were spurious build failures due to missing dependency on default-configs/pci.mak. Fix this by using `basename` to strip the directory path.

2013-01-26fw_cfg: Splash image loader can overrun a stack variable, fixMarkus Armbruster3-5/+6
read_splashfile() passes the address of an int variable as size_t * parameter to g_file_get_contents(), with a cast to gag the compiler. No problem on machines where sizeof(size_t) == sizeof(int). Happens to work on my x86_64 box (64 bit little endian): the least significant 32 bits of the file size end up in the right place (caller's variable file_size), and the most significant 32 bits clobber a place that gets assigned to before its next use (caller's variable file_type). I'd expect it to break on a 64 bit big-endian box. Fix up the variable types and drop the problematic cast.

2013-01-24Revert "serial: fix retry logic"Michael Tokarev1-3/+1
This reverts commit 67c5322d7000fd105a926eec44bc1765b7d70bdd: I'm not sure if the retry logic has ever worked when not using FIFO mode. I found this while writing a test case although code inspection confirms it is definitely broken. The TSR retry logic will never actually happen because it is guarded by an 'if (s->tsr_rety > 0)' but this is the only place that can ever make the variable greater than zero. That effectively makes the retry logic an 'if (0) I believe this is a typo and the intention was >= 0. Once this is fixed thoug I see double transmits with my test case. This is because in the non FIFO case, serial_xmit may get invoked while LSR.THRE is still high because the character was processed but the retransmit timer was still active. We can handle this by simply checking for LSR.THRE and returning early. It's possible that the FIFO paths also need some attention. Cc: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Even if the previous logic was never worked, new logic breaks stuff - namely, qemu -enable-kvm -nographic -kernel /boot/vmlinuz-$(uname -r) -append console=ttyS0 -serial pty the above command will cause the virtual machine to stuck at startup using 100% CPU till one connects to the pty and sends any char to it. Note this is rather typical invocation for various headless virtual machines by libvirt. So revert this change for now, till a better solution will be found.

2013-01-22iscsi: add support for iSCSI NOPs [v2]Peter Lieven1-0/+38
This patch will send NOP-Out PDUs every 5 seconds to the iSCSI target. If a consecutive number of NOP-In replies fail a reconnect is initiated. iSCSI NOPs help to ensure that the connection to the target is still operational. This should not, but in reality may be the case even if the TCP connection is still alive if there are bugs in either the target or the initiator implementation. v2: - track the NOPs inside libiscsi so libiscsi can reset the counter in case it initiates a reconnect.

2013-01-22qxl: change rom size to 8192Alon Levy1-6/+7
This is a simpler solution to 869981, where migration breaks since qxl's rom bar size has changed. Instead of ignoring fields in QXLRom, which is what has actually changed, we remove some of the modes, a mechanism already accounted for by the guest. The modes left allow for portrait and landscape only modes, corresponding to orientations 0 and 1. Orientations 2 and 3 are dropped. Added assert so that rom size will fit the future QXLRom increases via spice-protocol changes. This patch has been tested with 6.1.0.10015. With the newer 6.1.0.10016 there are problems with both "(flipped)" modes prior to the patch, and the patch loses the ability to set "Portrait" modes. But this is a separate bug to be fixed in the driver, and besides the patch doesn't affect the new arbitrary mode setting functionality.

This reverts commit a1cbfd554e11bb8af38c2f3e1f1574bf4c563cd2. Test isn't useless. scsi_req_enqueue() may finish the request (will actually happen for requests which don't trigger any I/O such as INQUIRY), then call usb_msd_command_complete() which in turn will set s->req to NULL after unref'ing it.

2013-01-21vnc: added initial websocket protocol supportTim Hardeck7-21/+591
This patch adds basic Websocket Protocol version 13 - RFC 6455 - support to QEMU VNC. Binary encoding support on the client side is mandatory. Because of the GnuTLS requirement the Websockets implementation is optional (--enable-vnc-ws). To activate Websocket support the VNC option "websocket"is used, for example "-vnc :0,websocket". The listen port for Websocket connections is (5700 + display) so if QEMU VNC is started with :0 the Websocket port would be 5700. As an alternative the Websocket port could be manually specified by using ",websocket=<port>" instead. Parts of the implementation base on Anthony Liguori's QEMU Websocket patch from 2010 and on Joel Martin's LibVNC Websocket implementation.
