[Bug 2019239] Proposed package removed from archive

Tue Jan 14 13:38:07 UTC 2025

The version of rtl8821ce in the proposed pocket of Jammy that was
purported to fix this bug report has been removed because one or more
bugs that were to be fixed by the upload have failed verification and
been in this state for more than 10 days.

Title:
  rtl8821ce should not build when CONFIG_CFG80211 is not enabled for
  linux-kvm

Status in rtl8821ce package in Ubuntu:
  Invalid
Status in rtl8821ce source package in Jammy:
  Confirmed

Bug description:
  [SRU Justification]

  Impact:
  jammy:linux-kvm does not have CONFIG_CFG80211 enabled.
  Module rtl8821ce-dkms requires it, otherwise, build will fail.
  Before last update to 5.5.2.1-0ubuntu11~0.22.04.1, build was not performed before because of this rule:

  # Only build on wifi enabled kernels
  if ! grep -q '^CONFIG_CFG80211=[ym]$' $kernel_source_dir/.config; then
  BUILD_EXCLUSIVE_KERNEL="^$"
  fi

  But the new version broke it because the rule that was overridden by
  BUILD_EXCLUSIVE_KERNEL="^5.15.*"

  This lead to new regression in autopkgtest for jammy:linux-
  kvm-5.15.0-1029.34.

  Fix:
  Add an if else condition so it will cover 2 cases:
  1. package won't build if kernel does not have CONFIG_CFG80211 enabled
  2. if 1 is true, package won't build if kernel version is not 5.15.

  Test plan:
  autopkgtest rtl8821ce fails during build with the error from below

  This happens if you run apt install rtl8821ce-dkms.

  Once the fix is there:
  1. module should skip build on linux-kvm or any kernel that has CONFIG_CFG80211 disabled.
  2. module should build on linux-generic (5.15)
  3. module should skip build on 5.19 kernels

  Tested locally in a VM:

  1. linux-kvm: 5.15.0-1033-kvm. Build is skipped:

  Regression potential:
  None. Build is skipped so no tests are performed.
