      MacOS: Handle changes to xdrproc_t definition · 9fa3a8ab
      Doug Goldstein 提交于
      With Mac OS X 10.9, xdrproc_t is no longer defined as:
      
      typedef bool_t (*xdrproc_t)(XDR *, ...);
      
      but instead as:
      
      typdef bool_t (*xdrproc_t)(XDR *, void *, unsigned int);
      
      For reference, Linux systems typically define it as:
      
      typedef bool_t (*xdrproc_t)(XDR *, void *, ...);
      
      The rationale explained in the header is that using a vararg is
      incorrect and has a potential to change the ABI slightly do to compiler
      optimizations taken and the undefined behavior. They decided
      to specify the exact number of parameters and for compatibility with old
      code decided to make the signature require 3 arguments. The third
      argument is ignored for cases that its not used and its recommended to
      supply a 0.

      libxl: fix dubious cpumask handling in libxlDomainSetVcpuAffinities · ba1bf100

      Rather than casting the virBitmap pointer to uint8_t* and then using
      the structure contents as a byte array, use the virBitmap API to determine
      the bitmap size and test each bit.

      Fix race in starting transient VMs · 89759301
      Daniel P. Berrange 提交于
      When starting a transient VM the first thing done is to check
      for duplicates. The check looks if there are any running VMs
      with the matching name/uuid. It explicitly allows there to
      be inactive VMs, so that a persistent VM can be temporarily
      booted with a different config.
      
      There is a race condition, however, where 2 or more clients
      try to create the same transient VM. The first client will
      cause a virDomainObjPtr to be added to the domain list, and
      it is inactive at this stage. The second client may then
      come along and see this inactive VM, and mistake it for a
      persistent VM.
      
      If the first VM fails to start its transient guest for any
      reason, then it'll remove the virDomainObjPtr from the list.
      The second client now has a virDomainObjPtr that it can try
      to boot, which libvirt no longer has a record of. The result
      can be a running QEMU process that is orphaned.
      
      It was also, however, possible for the virDomainObjPtr to be
      completely free'd which will cause libvirtd to crash in some
      scenarios.
      
      The fix is to only allow an existing inactive VM if it is
      marked as persistent.

      nodedev_hal: fix segfault when virDBusGetSystemBus fails · 87176d0c
      Ryota Ozaki 提交于
      Thie patch fixes the segfault:
          error : nodeStateInitialize:658 : DBus not available,
            disabling HAL driver: internal error: Unable to get DBus
            system bus connection: Failed to connect to socket
            /var/run/dbus/system_bus_socket: No such file or directory
          error : nodeStateInitialize:719 :  ?:
          Caught Segmentation violation dumping internal log buffer:
      
      This segfault occurs at the below VIR_ERROR:
        failure:
            if (dbus_error_is_set(&err)) {
                VIR_ERROR(_("%s: %s"), err.name, err.message);
      
      When virDBusGetSystemBus fails, the code jumps to the above failure
      path. However, the err variable is not correctly initialized
      before calling virDBusGetSystemBus. As a result, dbus_error_is_set
      may pass over the uninitialized err variable whose name or
      message may point to somewhere unknown memory region, which
      causes a segfault on VIR_ERROR.
      
      The new code initializes the err variable before calling
      virDBusGetSystemBus.

      Fix race condition reconnecting to vms & loading configs · f26701f5
      Daniel P. Berrange 提交于
      The following sequence
      
       1. Define a persistent QMEU guest
       2. Start the QEMU guest
       3. Stop libvirtd
       4. Kill the QEMU process
       5. Start libvirtd
       6. List persistent guests
      
      At the last step, the previously running persistent guest
      will be missing. This is because of a race condition in the
      QEMU driver startup code. It does
      
       1. Load all VM state files
       2. Spawn thread to reconnect to each VM
       3. Load all VM config files
      
      Only at the end of step 3, does the 'virDomainObjPtr' get
      marked as "persistent". There is therefore a window where
      the thread reconnecting to the VM will remove the persistent
      VM from the list.
      
      The easy fix is to simply switch the order of steps 2 & 3.
      
      In addition to this though, we must only attempt to reconnect
      to a VM which had a non-zero PID loaded from its state file.
