[Bug 1571506] Re: update-initramfs should include firmware from /lib/firmware/updates

[Brian Murray]

Hello Qiang, or anyone else affected,

Accepted initramfs-tools into bionic-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/initramfs-
tools/0.130ubuntu3.12 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: initramfs-tools (Ubuntu Bionic)
       Status: In Progress => Fix Committed

** Tags removed: verification-done
** Tags added: verification-needed verification-needed-bionic

Bug description:
  [Impact]

   * Firmware files under /lib/firmware/updates would not be
     processed when running update-initramfs
   
   * The kernel org specifies that this is a location where
     firmware can be stored, so we should search there

  [Test Case]

   * Stage some firmware under /lib/firmware/updates

   * Run update-initramfs and ensure that the firmware in 
     /lib/firmware/updates is found and included in the initramfs

  [Where problems could occur]

   * Since dpkg places no files in /lib/firmware/updates, we
     could end up picking up firmware changes that we did not intend

  [Other info]

   * This change already exists in groovy and beyond. It was pulled in
     when initramfs-tools version 0.137 was merged from Debian

  according to the kernel doc
  http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/firmware_class/README

  Linux kernel will search firmware from
  "/lib/firmware/updates/" UTS_RELEASE,
  "/lib/firmware/updates",
  "/lib/firmware/" UTS_RELEASE,
  "/lib/firmware"

  But the add module function in initramfs-tools won't search the
  "/lib/firmware/updates".

  This problem applies to all Ubuntu releases.

  Attach patch to fix this.
