2009-02-06Revert changes to fmopl.caliguori1-5/+22
fmopl.c was taken from MAME and doesn't include QEMU header files so we cannot use qemu_malloc in it. It happens to build because C is a silly language. Unfortunately, it doesn't play nicely with the QEMU headers so lets just revert the changes that were made to it.

Use the control virtqueue to allow the guest to enable and manipulate a VLAN filter table. This allows us to drop more packets the guest doesn't want to see.

2009-02-05qemu:virtio-net: Add additional MACs via a filter table (Alex Williamson)aliguori2-2/+109
Create a filter table and allow the guest to populate it with the MAC class control commands. We manage the size and usage of the filter table including enabling promiscuous and all-multi modes as necessary. The guest should therefore assume the table is infinite. Eventually this might allow us to bind directly to a hardware NIC and manipulate a physical MAC filter. The specifics of the TABLE_SET command are documented in virtio-net.h. Separate buffers in the same command are used for unicaste and multicast addresses for priority and sychronization. With this we can export the VIRTIO_NET_F_CTRL_RX feature bit.

2009-01-29check SCSI read/write requests against max LBA (Rik van Riel)aliguori1-0/+18
The bdrv layer uses a signed offset. Furthermore, block-raw-posix only seeks when that offset is positive. Passing a negative offset to block-raw-posix can result in data being written at the current seek cursor's position. It may be possible to exploit this to seek to the end of the disk and extend the virtual disk by writing data to a negative sector offset. After a reboot, this could lead to the guest having a larger disk than it had before. Close the hole by sanity checking the lba against the size of the disk.

Paul Brook pointed out that the number of sectors reported by the SCSI read capacity commands needs to be divided by s->cluster_size, because bdrv_get_geometry reports the number of 512 byte sectors, while emulated CDROMs report 2048 byte sectors back to the guest.

2009-01-28support >2TB SCSI disks (Rik van Riel)aliguori1-7/+46
Implement SCSI READ(16), WRITE(16) and SAI READ CAPACITY(16) commands, so SCSI disks larger than 2TB can work with guests that support these newer SCSI commands. The cast to (uint64_t) is needed because otherwise gcc will use a signed int, which gets sign extended into uint64_t lba, resulting in bad block numbers for READ 10 and READ 16 with block numbers larger than 2^31.

2009-01-28fix signed/unsigned overflows in SCSI disk (Rik van Riel)aliguori1-3/+6
Sector numbers can overflow on a virtual scsi disk of over 1TB in size. Qemu's bdrv_read expects an int64_t, so fix the overflow by going to that data type. On large disks, we clip the capacity to 2TB instead of returning "capacity modulo 2TB". Turn sector_count into an unsigned to prevent a signed/unsigned overflow with SCSI transfers larger than 2TB. We're unlikely to ever hit this bug, but fixing it is just one line.

The HPET emulation can disable the i8254 when the HPET is in legacy mode, thus emulating the i8254's behavior.

2009-01-24Floppy: Properly handle Sense Interrupt Status after FDC Resetblueswir11-12/+18
Original text below. Attached is a patch that changes how the emulated floppy controller replies to Sense Interrupt Status commands immediately after a controller reset. The specs state that after a Reset the 82078 goes into polling mode which needs four Sense Interrupt Status commands to be issued afterwards to clear the status of each drive. Currently we always respond to Sense Interrupt Status with a SEEK END instead of POLLING. This causes a problem with the SCO Openserver installer which is expects a POLLING state after reset. This patch returns a POLLING status for four Sense Interrupt Status requests immediately after a controller reset. This approach mirrors the way Bochs handles this situation. With the attached patch applied Openserver gets further when trying to load storage drivers from the floppy disk (blocked by another issue, patch on its way). I have successfully tested the floppy drive on the following OSs after applying this patch: Windows 98, Windows XP SP2, Linux x86 (SysRescCD 1.1.3 and Ubuntu 8.10).

2009-01-23fix endianness problem sharing the videoram buffermalc1-0/+7
[ The following text is in the "UTF-8" character set. ] [ Your display is set for the "koi8-r" character set. ] [ Some characters may be displayed incorrectly. ] This patch fixes vga rendering when the guest endianness differs from the host endianness: in this case we can only share the buffer if the bpp is 32 and we must change the pixelformat accordingly.
