This bug is awaiting verification that the linux-mtk/5.15.0-1030.34
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-jammy-linux-mtk' to 'verification-done-jammy-
linux-mtk'. If the problem still exists, change the tag 'verification-
needed-jammy-linux-mtk' to 'verification-failed-jammy-linux-mtk'.


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!

Title:
  Mass Storage Gadget driver truncates device >2TB

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Jammy:
  Fix Released

Bug description:
  [Impact]

  I tried to use f_mass_storage to expose a 16TB hard drive attached to 
Raspberry Pi to another computer.
  On the remote computer the recognised drive has incorrect capacity and the 
data is truncated.

  After some debugging I noted the problem is caused by a bug in the
  read capacity function of f_mass_storage in kernel version prior to
  5.15, which had already been fixed upstream in mainline kernel since
  v5.16

  
https://lore.kernel.org/all/20210914052728.23369-1-nikita.yo...@cogentembedded.com/

  I tried the kernel from https://github.com/raspberrypi/linux version
  rpi-5.16.y and confirmed that the problem is fixed at v5.16.

  I wonder if the fix can be backported to the Ubuntu kernel.

  Thank you very much!

  Current kernel package version: linux-raspi (5.15.0-1011.13) jammy
  Hardware: Raspberry Pi 4B

  [Fix]

  Backport commit bedbac5f66bf ("usb: gadget: storage: add support for
  media larger than 2T")

  [Test case]

  See above.

  [Where problems could occur]

  Modifications are limited to the USB gadget mass storage driver, so
  problems should only be seen on a client that uses this driver to
  expose a USB drive to an attached USB host.
