      qemu: Clear async job when p2p migration fails early · d325704a
      Jiri Denemark 提交于
      When p2p migration fails early because qemuMigrationIsAllowed or
      qemuMigrationIsSafe say migration should be cancelled, we fail to clear
      the migration-out async job. As a result of that, further APIs called
      for the same domain may fail with Timed out during operation: cannot
      acquire state change lock.

      This patch removed the "--filterwin2k" dnsmasq command line
      parameter which was unnecessary for domain specification,
      possibly blocked some usage, and was command line clutter.

      dnsmasq: avoid forwarding queries without a domain · 3fcc9096
      Gene Czarcinski 提交于
      dnsmasq is forwarding a number of queries upstream that should not
      be done.  There still remains an MX query for a plain name with no
      domain specified that will be forwarded is dnsmasq has --domain=xxx
      --local=/xxx/ specified. This does not happen with no domain name
      and --local=// ... not a libvirt problem.

      security: Fix libvirtd crash possibility · b2c5a911
      Martin Kletzander 提交于
      Fix for CVE-2012-4423.
      
      When generating RPC protocol messages, it's strictly needed to have a
      continuous line of numbers or RPC messages. However in case anyone
      tries backporting some functionality and will skip a number, there is
      a possibility to make the daemon segfault with newer virsh (version of
      the library, rpc call, etc.) even unintentionally.
      
      The problem is that the skipped numbers will get func filled with
      NULLs, but there is no check whether these are set before the daemon
      tries to run them. This patch very simply enhances one check and fixes
      that.

      rpc: Do not use timer for sending keepalive responses · 4d695acd
      Jiri Denemark 提交于
      When a libvirt API is called from the main event loop (which seems to be
      common in event-based glib apps), the client IO loop would properly
      handle keepalive requests sent by a server but will not actually send
      them because the main event loop is blocked with the API. This patch
      gets rid of response timer and the thread which is processing keepalive
      requests is also responsible for queueing responses for delivery.

      client rpc: Don't drop non-blocking calls · 5badf8c4
      Jiri Denemark 提交于
      So far, we were dropping non-blocking calls whenever sending them would
      block. In case a client is sending lots of stream calls (which are not
      supposed to generate any reply), the assumption that having other calls
      in a queue is sufficient to get a reply from the server doesn't work. I
      tried to fix this in b1e374a7 but
      failed and reverted that commit.
      
      With this patch, non-blocking calls are never dropped (unless the
      connection is being closed) and will always be sent.

      client rpc: Use event loop for writing · 8cb0d089
      Jiri Denemark 提交于
      Normally, when every call has a thread associated with it, the thread
      may get the buck and be in charge of sending all calls until its own
      call is done. When we introduced non-blocking calls, we had to add
      special handling of new non-blocking calls. This patch uses event loop
      to send data if there is no thread to get the buck so that any
      non-blocking calls left in the queue are properly sent without having to
      handle them specially. It also avoids adding even more cruft to client
      IO loop in the following patches.
      
      With this change in, non-blocking calls may see unpredictable delays in
      delivery when the client has no event loop registered. However, the only
      non-blocking calls we have are keepalives and we already require event
      loop for them, which makes this a non-issue until someone introduces new
      non-blocking calls.

      conf: Remove console stream callback only when freeing console helper · 2fd84d39
      Peter Krempa 提交于
      Commit ba226d33 tried to fix crash of
      the daemon when a domain with an open console was destroyed. The fix was
      wrong as it tried to remove the callback also when the stream was
      aborted, where at that point the fd stream driver was already freed and
      removed.
      
      This patch clears the callbacks with a helper right before the hash is
      freed, so that it doesn't interfere with other codepaths where the
      stream object is freed.

      security: Skip labeling resources when seclabel defaults to none · 3883ef03
      Jiri Denemark 提交于
      If a domain is explicitly configured with <seclabel type="none"/> we
      correctly ensure that no labeling will be done by setting
      norelabel=true. However, if no seclabel element is present in domain XML
      and hypervisor is configured not to confine domains by default, we only
      set type to "none" without turning off relabeling. Thus if such a domain
      is being started, security driver wants to relabel resources with
      default label, which doesn't make any sense.
      
      Moreover, with SELinux security driver, the generated image label lacks
      "s0" sensitivity, which causes setfilecon() fail with EINVAL in
      enforcing mode.

      fixed SegFault in virauth · b9964013
      Martin Kletzander 提交于
      No check for conn->uri being NULL in virAuthGetConfigFilePath (valid
      state) made the client segfault. This happens for example with these
      settings:
       - no virtualbox driver installed (modifies conn->uri)
       - no default URI set (VIRSH_DEFAULT_CONNECT_URI="",
         LIBVIRT_DEFAULT_URI="", uri_default="")
       - auth_sock_rw="sasl"
       - virsh run as root
      
      That are unfortunately the settings with fresh Fedora 17 installation
      with VDSM.
      
      The check ought to be enough as conn->uri being NULL is valid in later
      code and is handled properly.
