  * linux-buildinfo: pull out ABI information into its own package
    (LP: #1806380)
    - [Packaging] limit preparation to linux-libc-dev in headers
    - [Packaging] commonise debhelper invocation
    - [Packaging] ABI -- accumulate abi information at the end of the build
    - [Packaging] buildinfo -- add basic build information
    - [Packaging] buildinfo -- add firmware information to the flavour ABI
    - [Packaging] buildinfo -- add compiler information to the flavour ABI
    - [Packaging] buildinfo -- add buildinfo support to getabis
    - [Config] buildinfo -- add retpoline version markers
    - [Packaging] getabis -- handle all known package combinations
    - [Packaging] getabis -- support parsing a simple version
    - [Packaging] autoreconstruct -- base tag is always primary mainline version

  * signing: only install a signed kernel (LP: #1764794)
    - [Debian] usbip tools packaging
    - [Debian] Don't fail if a symlink already exists
    - [Debian] perf -- build in the context of the full generated local headers
    - [Debian] basic hook support
    - [Debian] follow rename of DEB_BUILD_PROFILES
    - [Debian] standardise on stage1 for the bootstrap stage in line with debian
    - [Debian] set do_*_tools after stage1 or bootstrap is determined

    - [Packaging] reconstruct -- automatically reconstruct against base tag
    - [Debian] add feature interlock with mainline builds
    - [Debian] Remove generated intermediate files on clean
    - [Packaging] prevent linux-*-tools-common from being produced from non linux
      packages
    - SAUCE: ubuntu: vbox -- elide the new symlinks and reconstruct on clean:
    - [Debian] Update to new signing key type and location
    - [Packaging] autoreconstruct -- generate extend-diff-ignore for links
    - [Packaging] reconstruct -- update when inserting final changes
    - [Packaging] update to Debian like control scripts
    - [Packaging] switch to triggers for postinst.d postrm.d handling
    - [Packaging] signing -- switch to raw-signing tarballs
    - [Packaging] signing -- switch to linux-image as signed when available
    - [Packaging] printenv -- add signing options
    - [Packaging] fix invocation of header postinst hooks
    - [Packaging] signing -- add support for signing Opal kernel binaries
    - [Debian] Use src_pkg_name when constructing udeb control files
    - [Debian] Dynamically determine linux udebs package name
    - [Packaging] handle both linux-lts* and linux-hwe* as backports
    - [Config] linux-source-* is in the primary linux namespace
    - [Packaging] lookup the upstream tag
    - [Packaging] switch up to debhelper 9
    - [Packaging] autopkgtest -- disable d-i when dropping flavours
    - [debian] support for ship_extras_package=false
    - [Debian] do_common_tools should always be on
    - [debian] do not force do_tools_common
    - [Packaging] skip cloud tools packaging when not building package
    - [debian] prep linux-libc-dev only if do_libc_dev_package=true

  * Packaging resync (LP: #1786013)
    - [Packaging] update helper scripts

  * kernel oops in bcache module (LP: #1793901)
    - SAUCE: bcache: never writeback a discard operation

  * iptables connlimit allows more connections than the limit when using
    multiple CPUs (LP: #1811094)
    - netfilter: connlimit: improve packet-to-closed-connection logic
    - netfilter: nf_conncount: fix garbage collection confirm race
    - netfilter: nf_conncount: don't skip eviction when age is negative

  * CVE-2019-6133
    - fork: record start_time late

  * test_095_kernel_symbols_missing_proc_self_stack failed on P-LTS
    (LP: #1813001)

Title:
  signing: only install a signed kernel

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Trusty:
  Fix Released
Status in linux source package in Xenial:
  Fix Committed

Bug description:
  We should switch the default kernel install to the signed kernel.
  This makes it much harder to uninstall the signed kernel in
  environments which enforce the kernel to be signed.  Boot loaders
  which can understand and validate it want the signed image, those
  which do not should ignore the appended signature.
