2010-02-23qcow2: Fix access after end of arrayKevin Wolf
If a write requests crosses a L2 table boundary and all clusters until the end of the L2 table are usable for the request, we must not look at the next L2 entry because we already have arrived at the end of the array.

2010-02-23net: Fix bogus "Warning: vlan 0 with no nics" with -deviceMarkus Armbruster
net_check_clients() prints this when an VLAN has host devices, but no guest devices. It uses VLANState members nb_guest_devs and nb_host_devs to keep track of these devices. However, -device does not update nb_guest_devs, only net_init_nic() does that, for -net nic. Check the VLAN clients directly, and remove the counters.

2010-02-23don't dereference NULL after failed strdupJim Meyering
Most of these are obvious NULL-deref bug fixes, for example, the ones in these files: block/curl.c net.c slirp/misc.c and the first one in block/vvfat.c. The others in block/vvfat.c may not lead to an immediate segfault, but I traced the two schedule_rename(..., strdup(path)) uses, and a failed strdup would appear to trigger this assertion in handle_renames_and_mkdirs: assert(commit->path); The conversion to use qemu_strdup in envlist_to_environ is not technically needed, but does avoid a theoretical leak in the caller when strdup fails for one value, but later succeeds in allocating another buffer(plausible, if one string length is much larger than the others). The caller does not know the length of the returned list, and as such can only free pointers until it hits the first NULL. If there are non-NULL pointers beyond the first, their buffers would be leaked. This one is admittedly far-fetched. The two in linux-user/main.c are worth fixing to ensure that an OOM error is diagnosed up front, rather than letting it provoke some harder-to-diagnose secondary error, in case of exec failure, or worse, in case the exec succeeds but with an invalid list of command line options. However, considering how unlikely it is to encounter a failed strdup early in main, this isn't a big deal. Note that adding the required uses of qemu_strdup here and in envlist.c induce link failures because qemu_strdup is not currently in any library they're linked with. So for now, I've omitted those changes, as well as the fixes in target-i386/helper.c and target-sparc/helper.c. If you'd like to see the above discussion (or anything else) in the commit log, just let me know and I'll be happy to adjust. >From 9af42864fd1ea666bd25e2cecfdfae74c20aa8c7 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering@redhat.com> Date: Mon, 8 Feb 2010 18:29:29 +0100 Subject: [PATCH] don't dereference NULL after failed strdup Handle failing strdup by replacing each use with qemu_strdup, so as not to dereference NULL or trigger a failing assertion. * block/curl.c (curl_open): s/\bstrdup\b/qemu_strdup/ * block/vvfat.c (init_directories): Likewise.

OK we are fooled by the json lexer and parser. As we use %I64d to print 'long long' variables in Win32, but lexer and parser only deal with %lld but not %I64d, this patch add support for %I64d and solve 'info pci', 'powser_reset' and 'power_powerdown' assert failure in Win32.

2010-02-23segfault due to buffer overrun in usb-serialDavid S. Ahern
This fixes a segfault due to buffer overrun in the usb-serial device. The memcpy was incrementing the start location by recv_used yet, the computation of first_size (how much to write at the end of the buffer before wrapping to the front) was not accounting for it. This causes the next element after the receive buffer (recv_ptr) to get overwritten with random data.

2010-01-19scsi: device version propertyGerd Hoffmann
This patch adds a new property named 'ver' to scsi-disk which allows to specify the version which the virtual disk/cdrom should report to the guest. By default this is the qemu version (i.e. 0.12). usage: -drive if=none,id=disk,file=... -device lsi -device scsi-disk,drive=disk,bus=scsi.0,unit=0,ver=42 You can also switch the version for all scsi drives using: -global scsi-disk.ver=42 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> (cherry picked from commit 383b4d9b79e3a71b1d5cadd34989b1c0e2a05832)

2010-01-19QMP: Emit asynchronous events on all QMP monitorsAdam Litke
When using a control/QMP monitor in tandem with a regular monitor, asynchronous messages can get lost depending on the order of the QEMU program arguments. QEMU events issued by monitor_protocol_event() always go to cur_mon. If the user monitor was specified on the command line first (or it has ,default), the message will be directed to the user monitor (not the QMP monitor). Additionally, only one QMP session is currently able to receive async messages. To avoid this confusion, scan through the list of monitors and emit the message on each QMP monitor.
