      qemu: Avoid using stale data in virDomainGetBlockInfo · b7992595
      Jiri Denemark 提交于
      CVE-2013-6458
      
      Generally, every API that is going to begin a job should do that before
      fetching data from vm->def. However, qemuDomainGetBlockInfo does not
      know whether it will have to start a job or not before checking vm->def.
      To avoid using disk alias that might have been freed while we were
      waiting for a job, we use its copy. In case the disk was removed in the
      meantime, we will fail with "cannot find statistics for device '...'"
      error message.

      qemu: Do not access stale data in virDomainBlockStats · db86da5c
      Jiri Denemark 提交于
      CVE-2013-6458
      https://bugzilla.redhat.com/show_bug.cgi?id=1043069
      
      When virDomainDetachDeviceFlags is called concurrently to
      virDomainBlockStats: libvirtd may crash because qemuDomainBlockStats
      finds a disk in vm->def before getting a job on a domain and uses the
      disk pointer after getting the job. However, the domain in unlocked
      while waiting on a job condition and thus data behind the disk pointer
      may disappear. This happens when thread 1 runs
      virDomainDetachDeviceFlags and enters monitor to actually remove the
      disk. Then another thread starts running virDomainBlockStats, finds the
      disk in vm->def, and while it's waiting on the job condition (owned by
      the first thread), the first thread finishes the disk removal. When the
      second thread gets the job, the memory pointed to be the disk pointer is
      already gone.
      
      That said, every API that is going to begin a job should do that before
      fetching data from vm->def.

      Fix segmentation fault when accessing default qemu machine type · 72953074
      Yudai Yamagish 提交于
      This patch fixes a segmentation fault when creating new virtual machines using QEMU.
      The segmentation fault is caused by commit f4183068
      and commit cbb6ec42.
      
      In virQEMUCapsProbeQMPMachineTypes, when copying machines to qemuCaps, "none" is skipped.
      Therefore, the value of i and "qemuCaps->nmachineTypes - 1" do not always match.
      However, defIdx value (used to call virQEMUCapsSetDefaultMachine) is set using the value in i
      when the array elements are in qemuCaps->nmachineTypes - 1.
      So, when libvirt tries to create virtual machines using the default machine type,
      qemuCaps->machineTypes[defIdx] is accessed and since the defIdx is NULL, it results in segmentation fault.

      event: make deregister return value match docs · 31b5bad9
      Eric Blake 提交于
      Ever since their introduction (commit 1509b802 in v0.5.0 for
      virConnectDomainEventRegister, commit 44457238 in v0.8.0 for
      virConnectDomainEventDeregisterAny), the event deregistration
      functions have been documented as returning 0 on success;
      likewise for older registration (only the newer RegisterAny
      must return a non-zero callbackID).  And now that we are
      adding virConnectNetworkEventDeregisterAny for v1.2.1, it
      should have the same semantics.
      
      Fortunately, all of the stateful drivers have been obeying
      the docs and returning 0, thanks to the way the remote_driver
      tracks things (in fact, the RPC wire protocol is unable to
      send a return value for DomainEventRegisterAny, at least not
      without adding a new RPC number).  Well, except for vbox,
      which was always failing deregistration, due to failure to
      set the return value to anything besides its initial -1.
      
      But for local drivers, such as test:///default, we've been
      returning non-zero numbers; worse, the non-zero numbers have
      differed over time.  For example, in Fedora 12 (libvirt 0.8.2),
      calling Register twice would return 0 and 1 [the callbackID
      generated under the hood]; while in Fedora 20 (libvirt 1.1.3),
      it returns 1 and 2 [the number of callbacks registered for
      that event type].  Since we have changed the behavior over
      time, and since it differs by local vs. remote, we can safely
      argue that no one could have been reasonably relying on any
      particular behavior, so we might as well obey the docs, as well
      as prepare callers that might deal with older clients to not be
      surprised if the docs are not strictly followed.
      
      For consistency, this patch fixes the code for all drivers,
      even though it only makes an impact for vbox and for local
      drivers.  By fixing all drivers, future copy and paste from
      a remote driver to a local driver is less likely to
      reintroduce the bug.
      
      Finally, update the testsuite to gain some coverage of the
      issue for local drivers, including the first test of old-style
      domain event registration via function pointer instead of
      event id.

      qemuProcessStop: Don't overwrite any errors · 088ff08c
      Michal Privoznik 提交于
      Currently, the qemuProcessStop tries to open the domain log file
      and saves the original error afterwards. Then all the cleanup is
      done after which the error is restored back. This has however one
      flaw: if opening of the log file fails an error is reported,
      which results in previous error being overwritten (the useful
      one, e.g. "PCI device XXXX:XXXX could not be found"). Hence, user
      sees something like:

      Add a range check for supported numa memory placement modes provided by

      the user is able to provide a (yet) unknown mode which is then stored in
      the domain definition. This potentially causes a NULL dereference when
      the defintion is formatted into the XML.

       virsh numatune DOMNAME --mode 6 --nodeset 0

      Do not leave the PCI address of the primary video card set

      Since QEMU 1.6 (QEMU_CAPS_VIDEO_PRIMARY) we allow the primary
      video card to be on other slots than 0000:00:02.0 (as we use
      -device instead of -vga).
      
      However we fail to assign it an address if:
      * another device explicitly uses 0000:00:02.0 and
      * the primary video device has no address specified
      
      On the first pass, we have set the address to default, then checked
      if it's available, leaving it set even if it wasn't. This address
      got picked up by the second pass, resulting in a conflict:
      
      XML error: Attempted double use of PCI slot 0000:00:02.0

      maint: improve VIR_ERR_NO_SUPPORT usage · baa72449
      Eric Blake 提交于
      We weren't very consistent in our use of VIR_ERR_NO_SUPPORT; many
      users just passed __FUNCTION__ on, while others passed "%s" to
      silence over-eager compilers that warn about __FUNCTION__ not
      containing any %.  It's nicer to route all these uses through
      a single macro, so that if we ever need to change the reporting,
      we can do it in one place.
      
      I verified that 'virsh -c test:///default qemu-monitor-command test foo'
      gives the same error message before and after this patch:
      error: this function is not supported by the connection driver: virDomainQemuMonitorCommand
      
      Note that in libvirt.c, we were inconsistent on whether virDomain*
      API used virLibConnError() (with VIR_FROM_NONE) or virLibDomainError()
      (with VIR_FROM_DOMAIN); this patch unifies these errors to all use
      VIR_FROM_NONE, on the grounds that it is unlikely that a caller
      learning that a call is unimplemented can do anything in particular
      with extra knowledge of which error domain it belongs to.
      
      One particular change to note is virDomainOpenGraphics which was
      trying to fail with VIR_ERR_NO_SUPPORT after a failed
      VIR_DRV_SUPPORTS_FEATURE check; all other places that fail a
      feature check report VIR_ERR_ARGUMENT_UNSUPPORTED.

      maint: avoid nested public calls · 8f6c845f
      Eric Blake 提交于
      Having one API call into another is generally not good; among
      other issues, it gives confusing logs, and is not quite as
      efficient.
      
      This fixes several instances, but not all: we still have instances
      in both libvirt.c and in backend hypervisors (lxc and qemu) calling
      the public virTypedParamsGetString and friends, which dispatch
      errors immediately.  I'm not sure if it is worth trying to clean
      that up in a separate patch (such a cleanup may be easiest by
      separating the public function into a wrapper around the internal,
      then tweaking internal.h so that internal users directly use the
      internal function).

      maint: reset error on entrance to public API · f06d55da
      Eric Blake 提交于
      We document that calling any public API wipes out all prior
      libvirt errors in the same thread; but weren't obeying this
      style in a few functions.
      
      There are a couple of nested uses of virConnectRef (in lxc
      and qemu reboot paths), but they should not be affected by
      this change in semantics since there should not be any
      previous error getting nuked (a later patch will clean up
      the nested calls, along with abuse of virConnectClose on
      cleanup paths which DOES nuke errors).

      maint: move debug statements first in public API · ff658434
      Eric Blake 提交于
      Most of our public APIs emit a debug log on entry, prior to anything
      else.  There were a few exceptions where obvious failures were not
      logged, so fix those.  When moving a debug earlier, this patch also
      makes sure to avoid any NULL dereference during the log (the APIs
      are supposed to gracefully fail if the user passes NULL for the object).
      
      However, do NOT use VIR_DEBUG prior to virInitialize, since setting
      up the error reporting can change where VIR_DEBUG output would be
      routed.  Instead add documentation to virGlobalInit, virInitialize,
      and virGetVersion that better explains initialization.

      Prior to this patch, an attempt to register an event without an

      Now it gives the much nicer:
      
      libvirt:  error : internal error: could not initialize domain event timer
      
      This also avoids hiding other reasonable error messages, such as
