[Bug 2085453] Re: New upstream core91 release

[You-Sheng Yang]

> I wonder if there's any technical reason for dropping those 3 patches?

You reviewers should really make up your minds to setup a common
standard for SRU process. The three patches are for fix build failure
against v6.12 kernel, and certainly Oracular has no v6.12 kernel. The
prior SRU for another package ask me to drop such changes, but now
you're asking for technical reason for the drop.

No! There is no technical reason. It's all about your review policy.

> there's one slight difference in debian/patches/0015-backports-
genetlink-hold-RCU-in-genlmsg_mcast.patch,

That patch is for an kernel API changing fix that has been backported to
stable v6.11.x. It is originated from bug 2083994 because that fix was
first landed to v6.12. But while changes for bug 2083994 were dropped at
backport, and yet this change is mandatory for compiling against v6.11.x
kernels, it's therefore re-targeted to bug 2085453.

> can you please make a case for how this matches the SRU policy or
point us to the corresponding SRU exception?

I don't understand. I've put that in the very first line of the Impact
section "New upstream release. For Oracular, we need it to load -94 FW
API firmware in linux-oem-6.11 kernel."

> Please also consider if a more targeted fix, based on v89, to just fix
the build with more recent kernels would be more appropriate here,
instead of the full v91 backport.

You don't know how it's versioned. You don't know what it means to
support -94 firmware based on core89 release. You don't make suggestion
that cannot work. Please.

Title:
  New upstream core91 release

Status in backport-iwlwifi-dkms package in Ubuntu:
  Fix Released
Status in backport-iwlwifi-dkms source package in Oracular:
  In Progress
Status in backport-iwlwifi-dkms source package in Plucky:
  Fix Released

Bug description:
  [SRU Justification]

  [Impact]

  New upstream release. For Oracular, we need it to load -94 FW API
  firmware in linux-oem-6.11 kernel.

  Also, need this to make Oracular kernel in next SRU be buildable as
  there is upstream stable update based on v6.11.6 that will break it
  (see bug 2089385)

  [Fix]

  Upstream branch release core91 in
  https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-
  iwlwifi.git/log/?h=release/core91

  [Test Case]

  So far there is no official v6.12 kernel available, but one may install experimental linux-unstable/plucky kernels from https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/experimental-unstable. With that install backport-iwlwifi-dkms from -proposed pocket, and issue:
  ```
  $ sudo dkms install backport-iwlwifi/0~91.12629-gite112ecce -k $(uname -r)
  $ sudo dkms status
  ```
  The installation should complete successfully.

  Install firmware from bug 2085547. With -94 FW depending hardware such as Intel(R) Wi-Fi 7 BE201 installed, the iwlwifi device should be up and running.
  ```
  $ ip a
  ... # should gives basic info of the wlan interface
  $ nmtui # Use nmtui to connect wireless stations
  ```

  [Where problems could occur]

  While this is an initial packaging of Intel backport-iwlwifi core91
  release, expect further issues/updates when necessary.

  [Other Info]

  New release, nominate for Plucky. While this is also needed by
  oem-6.11 for oem projects as a short term solution, nominate for
  Oracular as well.
