[Bug 1417313] Re: [Hyper-V] vmbus: incorrect device name is printed when child device is unregistered

 

Thanks for this, we will take this kernel and test.  The issue is
intermittent and would likely only show up during stress tests, so it
may take a few days for results.

Thanks!

Title:
  [Hyper-V] vmbus: incorrect device name is printed when child device is
  unregistered

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Precise:
  Triaged

Bug description:
  This issue impacts Ubuntu 12.04.

  Whenever a device is unregistered in vmbus_device_unregister
  (drivers/hv/vmbus_drv.c), the device name in the log message may
  contain garbage as the memory has already been freed by the time
  pr_info is called.  Log example:

    [ 3149.170475] hv_vmbus: child device àõsèè0_5 unregistered

  By logging the message just before calling device_unregister, the
  correct device name is printed:

    [ 3145.034652] hv_vmbus: child device vmbus_0_5 unregistered

  
  This issue has been resolved with the upstream patch: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/hv/vmbus_drv.c?id=84672369ffb98a51d4ddf74c20a23636da3ad615
