      blockdev: Refuse to open encrypted image unless paused · c3adb58f
      Markus Armbruster 提交于
      Opening an encrypted image takes an additional step: setting the key.
      Between open and the key set, the image must not be used.
      
      We have some protection against accidental use in place: you can't
      unpause a guest while we're missing keys.  You can, however, hot-plug
      block devices lacking keys into a running guest just fine, or insert
      media lacking keys.  In the latter case, notifying the guest of the
      insert is delayed until the key is set, which may suffice to protect
      at least some guests in common usage.
      
      This patch makes the protection apply in more cases, in a rather
      heavy-handed way: it doesn't let you open encrypted images unless
      we're in a paused state.
      
      It doesn't extend the protection to users other than the guest (block
      jobs?).  Use of runstate_check() from block.c is disgusting.  Best I
      can do right now.

      block: Fix error path segfault in bdrv_open() · eb909c7f
      Kevin Wolf 提交于
      Using an invalid option for a block device that is opened with
      BDRV_O_PROTOCOL led to drv = NULL, and when trying to include the driver
      name in the error message, qemu dereferenced it:
      
          $ x86_64-softmmu/qemu-system-x86_64 -drive file=/tmp/test.qcow2,file.foo=bar
          Segmentation fault (core dumped)
      
      With this patch applied, the expected error message is printed:
      
          $ x86_64-softmmu/qemu-system-x86_64 -drive file=/tmp/test.qcow2,file.foo=bar
          qemu-system-x86_64: -drive file=/tmp/test.qcow2,file.foo=bar: could
          not open disk image /tmp/test.qcow2: Block protocol 'file' doesn't
          support the option 'foo'
