2009-05-08Improve block range checksKevin Wolf1-1/+6
This patch makes the range checks for block requests more strict: It fixes a potential integer overflow and checks for negative offsets. Also, it adds the check for compressed writes. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-08e1000: Do not reinit pci config space to 0Amit Shah1-1/+0
pci_register_device already mallocs the pci config space buffer filled with zeroes. Doing this again breaks some default config space writes like setting the subsystem vendor id and subsystem device id.

2009-05-08AIO deletion race fixAlexander Graf1-1/+2
When deleting an fd event there is a chance the object doesn't get deleted, but only ->deleted set positive and deleted somewhere later. Now, if we create a handler for the fd again before the actual deletion occurs, we end up writing data into an object that has ->deleted set, which is obviously wrong. I see two ways to fix this: 1. Don't return ->deleted objects in the search 2. Unset ->deleted in the search This patch implements 1. which feels safer to do. It fixes AIO issues I've seen with curl, as libcurl unsets fd event listeners pretty frequently. Signed-off-by: Alexander Graf <alex@csgraf.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-08reset state for load_linuxGlauber Costa1-4/+11
The linux loader is just an option rom like any other, just with some special requirements. Right now, our option rom resetting mechanism is not being applied to it. As a result, users using -kernel will not be able to successfully reboot their machines This patch fixes it by saving all the data we generated in the load_linux() function, to be used later by the option rom resetting mechanism.

2009-05-08register reset handler for option_romsGlauber Costa1-0/+24
Currently, boot options are not preserved across a system reset. option roms can modify themselves, or can for instance restore the real int 0x19 vector after they tried to boot from it. To properly do that, we need a reset handler registered to deal with option roms. This patch is based on current version on qemu-kvm.git Signed-off-by: Glauber Costa <glommer@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-04-17hpet: Fix emulation of HPET_TN_SETVAL (Jan Kiszka)aliguori1-1/+1
While Intel's spec is not that clear here, latest changes to Linux' HPET code (commit c23e253e67c9d8a91a0ffa33c1f571a17f0a2403, "x86: hpet: stop HPET_COUNTER when programming periodic mode") strongly suggest that HPET_TN_SETVAL rather means: Set _both_ the comparator value and register.

2009-04-05Fix (at least one cause of) qcow2 corruption. (Nolan Leake)aliguori1-0/+4
qcow2's get_cluster_offset() scans forward in the l2 table to find other clusters that have the same allocation status as the first cluster. This is used by (among others) qcow_is_allocated(). Unfortunately, it was not checking to be sure that it didn't fall off the end of the l2 table. This patch adds that check. The symptom that motivated me to look into this was that bdrv_is_allocated() was returning false when there was in fact data there. This is one of many ways this bug could lead to data corruption. I checked the other place that scans for consecutive unallocated blocks (alloc_cluster_offset()) and it appears to be OK: nb_clusters = MIN(nb_clusters, s->l2_size - l2_index); appears to prevent the same problem from occurring.

Backport of revisions 6792, 6916, 6919 from trunk. git-svn-id: svn://svn.savannah.nongnu.org/qemu/branches/stable_0_10@6960 c046a42c-6fe2-441c-8c8c-71466251a162
2009-03-28char: Fix closing of various char devices (Jan Kiszka)aliguori1-2/+19
This patch fixes several issues around closing char devices. Affected were pty (timer was left behind, even running), udp (no close handling at all) and tcp (missing async IO handler cleanup). The bugs either caused segfaults or stalled the qemu process. So far, hot-unplugging USB serial adapters suffered from this.
