  We have observed that OS is sending the IO's (SCSI Read/Write) with incorrect 
Scatter Gather Buffer address .

  i.e

   OS is sending the IO with 64 bit Scatter Gather Buffer address , such
  that if we add the length with buffer address then it causes the roll
  over .

  Here is the data we captured in our driver (Printed the SGE details
  which was sent by OS)

  sgl_ptr->Address = f000
  [14547.313240]
  sgl_ptr->Length = 1000
  [14547.313241]
  sge_count = 18
  [14547.313242]
  cmd->index = 9d9

[Kernel-packages] [Bug 1795453] Re: [SRU] IO's are issued with incorrect Scatter Gather Buffer

2019-02-13 Thread Kleber Sacilotto de Souza
Hi,

This bug has been marked as affecting both Bionic and Cosmic main linux
packages, so the fix has been applied as such. Please note that comment
#67 is requesting verification with the Cosmic kernel only (4.18), the
Bionic kernel (4.15) has not been published to -proposed yet. Another
comment will be added automatically when the Bionic kernel hits
-proposed, which is scheduled to happen until the end of this week.

The verification is requested only for the main kernels, however since
xenial/linux-hwe is based on bionic/linux (4.15), it will also receive
the fix with the next update.

Thank you.

[Kernel-packages] [Bug 1795453] Re: [SRU] IO's are issued with incorrect Scatter Gather Buffer

2019-02-11 Thread Brad Figg
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
cosmic' to 'verification-done-cosmic'. If the problem still exists,
change the tag 'verification-needed-cosmic' to 'verification-failed-
cosmic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  We have observed that OS is sending the IO's (SCSI Read/Write) with incorrect 
Scatter Gather Buffer address .

  i.e

   OS is sending the IO with 64 bit Scatter Gather Buffer address , such
  that if we add the length with buffer address then it causes the roll
  over .

  Here is the data we captured in our driver (Printed the SGE details
  which was sent by OS)

  sgl_ptr->Address = f000
  [14547.313240]
  sgl_ptr->Length = 1000
  [14547.313241]
  sge_count = 18
  [14547.313242]
  cmd->index = 9d9

Can we also get the above fixes in Xenial HWE kernels?
I suppose Xenial HWE kernel is a fork of bionic LTS kernels..

I built test kernels for bionic and cosmic with the fix applied. Please
can you test it and check if the problem is solved?

You can download the debian packages from:

Title:
  [SRU] IO's are issued with incorrect Scatter Gather Buffer

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  [Impact]
  We have observed that OS is sending the IO's (SCSI Read/Write) with incorrect 
Scatter Gather Buffer address .

  i.e

   OS is sending the IO with 64 bit Scatter Gather Buffer address , such
  that if we add the length with buffer address then it causes the roll
  over .

  Here is the data we captured in our driver (Printed the SGE details
  which was sent by OS)

  sgl_ptr->Address = f000
  [14547.313240]
  sgl_ptr->Length = 1000
  [14547.313241]
  sge_count = 18
  [14547.313242]
  cmd->index = 9d9

  Note : This issue is observed only when virtualization is enabled
