* check SCSI read/write requests against max LBA (Rik van Riel)aliguori2009-01-291-0/+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.

* MTRR support on x86, part 2 (Carl-Daniel Hailfinger)aliguori2009-01-293-1/+34
| | | | | | | | | | | | | | | | | | | | | | Load and save MTRR state together with machine state. Add support for the MTRRcap MSR which is used by the latest Bochs BIOS and some operating systems. Fix a typo in ext2_feature_name. With this patch, MTRR emulation should be good enough to not trigger any sanity checks in well behaved BIOS/kernel code. Some corner cases for BIOS/firmware usage remain to be implemented, but that can be deferred to another patch. Also, MTRR accesses on hardware not supporting MTRRs should cause #GP. That can be enforced by another patch as well.

* Don't notify virtio devices before S_DRIVER_OK (Mark McLoughlin)aliguori2009-01-291-0/+3
| | | | | | | | | | | | | | | | Current Linux guests oops if the host notifies of a config change before a driver has been bound to the device.

* fix raw_aio_read\write error handling (Stefano Stabellini)aliguori2009-01-291-15/+21
| | | | | | | | | | | | | | | | | | | Currently when qemu_paio_read or qemu_paio_write return an error we call qemu_aio_release without removing the request from the list. I know that in the current implementation qemu_paio_write\read don't return any error, but still the behavior is wrong, especially considering that the implementation of these two functions is likely to change in is the future. This patch fixes the problem adding a raw_aio_remove function that removes the callback from the queue and also calls qemu_aio_release. raw_aio_remove is called by raw_aio_read, raw_aio_write and raw_aio_cancel.

* SCSI divide capacity by s->cluster_size (Rik van Riel)aliguori2009-01-281-0/+2
| | | | | | | | | | | | | | | | | | | 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. This has no consequences for emulated hard disks, which use a cluster size of 1. aliguori: fixed typo Signed-off-by: Rik van Riel <riel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6469 c046a42c-6fe2-441c-8c8c-71466251a162

| | | | | | | | | | | | | | | | | 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.

* fix signed/unsigned overflows in SCSI disk (Rik van Riel)aliguori2009-01-281-3/+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.

| | | | | | | | | | | | | | | It seems that the conversion of the kernel-delivered eflags state into qemu's internal split representation was once needed in an older kvm design (register read-back may have taken place from inside cpu_exec). Today it is plain wrong and causes incorrect cpu state reporting (gdb, monitor) and should also corrupt its saving (savevm, migration). Drop the related lines.

* MTRR support on x86 (Carl-Daniel Hailfinger)aliguori2009-01-262-1/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase ignores MTRR (Memory Type Range Register) configuration writes and reads because Qemu does not implement caching. All BIOS/firmware in know of for x86 do implement a mode called Cache-as-RAM (CAR) which locks down the CPU cache lines and uses the CPU cache like RAM before RAM is enabled. Qemu assumes RAM is accessible from the start, but it would be nice to be able to run real BIOS/firmware in Qemu. For that, we need CAR support and for CAR support we have to support MTRRs. This patch is a first step in that direction. MTRRs are MSRs supported by all recent x86 CPUs, even old i586. Besides influencing cache, the MTRRs can be written and read back, so discarding MTRR writes violates the expectations of existing code out there. An added benefit of this patch is that it fixes the following Linux kernel error message present in recent kernels (provided the BIOS has the recent MTRR patches applied): ------------[ cut here ]------------ WARNING: at arch/x86/kernel/cpu/mtrr/main.c:1500 mtrr_trim_uncached_memory+0x382/0x384() WARNING: strange, CPU MTRRs all blank?

* Define PCI vendor and device IDs in pci.h (Stuart Brady)aliguori2009-01-2629-159/+157
| | | | | | | | | | | | | | | This patch defines PCI vendor and device IDs in pci.h (matching those from Linux's pci_ids.h), and uses those definitions where appropriate. Change from v1: Introduces pci_config_set_vendor_id() / pci_config_set_device_id() accessors as suggested by Anthony Liguori.

* vnc fixes and improvements (Stefano Stabellini)aliguori2009-01-263-6/+34
| | | | | | | | | | | | | | | | | this patch fixes a bug and improves the generic pixel conversion function in vnc.c. The bug is that when a new vnc client connects we need to reset the flag has_WMVi but currently we don't. The generic pixel conversion function is vnc_convert_pixel and currently is not very efficient since uses the division and multiplication operators. To make it more efficient I changed to use bit shift operators instead.

* Use the default subsystem vendor ID for virtio devices (Mark McLoughlin)aliguori2009-01-264-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A subsystem vendor ID of zero isn't allowed, so we use our default ID. Gerd points out that although the PCI subsystem vendor ID is treated by the guest as the virtio vendor ID: /* we use the subsystem vendor/device id as the virtio vendor/device * id. this allows us to use the same PCI vendor/device id for all * virtio devices and to identify the particular virtio driver by * the subsytem ids */ vp_dev->vdev.id.vendor = pci_dev->subsystem_vendor; vp_dev->vdev.id.device = pci_dev->subsystem_device; it looks like only the device ID is used right now: # grep virtio modules.alias alias virtio:d00000001v* virtio_net alias virtio:d00000002v* virtio_blk alias virtio:d00000003v* virtio_console alias virtio:d00000004v* virtio-rng alias virtio:d00000005v* virtio_balloon alias pci:v00001AF4d*sv*sd*bc*sc*i* virtio_pci alias virtio:d00000009v* 9pnet_virtio so setting the subsystem vendor id to something != zero shouldn't cause trouble.

* Support epoch of 1980 in RTC emulation for MIPS Magnumaurel322009-01-247-11/+20
| | | | | | | | | | | | | | | | On the MIPS Magnum, the time that is held in the RTC's NVRAM should be relative to midnight on 1980-01-01. This patch adds an extra parameter to rtc_init(), allowing different epochs to be used. For the Magnum, 1980 is specified, and for all other machines, 2000 is specified. I've not modified the handling of the century byte, as with an epoch of 1980 and a year of 2009, one could argue that it should hold either 0, 1, 19 or 20. NT 3.50 on MIPS does not read the century byte.
