amd64-microcode (3.20171205.1) unstable; urgency=high

  * New microcode updates (closes: #886382):
    sig 0x00800f12, patch id 0x08001213, 2017-12-05
    Thanks to SuSE for distributing these ahead of AMD's official release!
  * Add IBPB support for family 17h AMD processors (CVE-2017-5715)
  * README: describe source for faml17h microcode update
  * Upload to unstable to match IBPB microcode support on Intel in Debian
    unstable.
  * WARNING: requires at least kernel 4.15, 4.14.13, 4.9.76, 4.4.111 (or a
    backport of commit f4e9b7af0cd58dd039a0fb2cd67d57cea4889abf
    "x86/microcode/AMD: Add support for fam17h microcode loading") otherwise
    it will not be applied to the processor.

  * NEWS.debian: fix minor typo
  * debian/control, debian/compat: bump debhelper compat mode to 9

  * debian/: prefix binary-package control files with package name
  * debian/control: recommend tiny-initramfs as an alternative to
    initramfs-tools tiny-initramfs specifically supports early microcode
    updates, so it is a viable alternative to initramfs-tools
    (closes: #839882)

amd64-microcode (3.20160316.1) unstable; urgency=low

  * Bump major version number to 3: early-initramfs support
  * Support is now restricted to Linux kernel 3.14 and later.  For older
    kernels, please use the version 2 (older) branch of the package.
  * Implement early-initramfs mode, and remove normal mode
    * debian/control: add versioned recommends for initramfs-tools and
      dracut.  Note that dracut 044 is required for Linux 4.4 and later,
      otherwise dracut 040 would be enough
    * debian/default: add early mode, remove normal mode from comments
    * initramfs hook: use cpio to generate an early-initramfs with
      microcode for all processors, blacklist kernels older than 3.14,
      and remove normal mode support.
    * initramfs.init-premount: remove, not needed for early-initramfs
    * debian/rules: don't install init-premount initramfs script.
  * initramfs.hook: detect a missing microcode.ko and don't attempt to
    force_load() it.  In verbose mode, log when the microcode driver is
    modular.  For Linux 4.4 and later, skip the module loading logic
    (closes: #809444)
  * README.Debian: update for early initramfs support, and add information
    on how to disable early updates using the dis_ucode_ldr kernel boot
    parameter
  * Support for x32 was enabled in debian/control for the 2.20160316.1
    upload, but the changelog did not record this by mistake.  The missing
    entry was retroactively added to debian/changelog by this upload

amd64-microcode (2.20160316.1) unstable; urgency=critical

  * Upstream release 20160316 built from linux-firmware:
    + Updated Microcodes:
      sig 0x00600f20, patch id 0x0600084f, 2016-01-25
    + This microcode updates fixes a critical erratum on NMI handling
      introduced by microcode patch id 0x6000832 from the 20141028 update.
      The erratum is also present on microcode patch id 0x6000836.
    + THIS IS A CRITICAL STABILITY AND SECURITY UPDATE FOR THE EARLIER
      AMD PILEDRIVER PROCESSORS, including:
      + AMD Opteron 3300, 4300, 6300
      + AMD FX "Vishera" (43xx, 63xx, 83xx, 93xx, 95xx)
      + AMD processors with family 21, model 2, stepping 0
  * Robert Święcki, while fuzzing the kernel using the syzkaller tool,
    uncovered very strange behavior on an AMD FX-8320, later reproduced on
    other AMD Piledriver model 2, stepping 0 processors including the Opteron
    6300.  Robert discovered, using his proof-of-concept exploit code, that
    the incorrect behavior allows an unpriviledged attacker on an unpriviledged
    VM to corrupt the return stack of the host kernel's NMI handler.  At best,
    this results in unpredictable host behavior.  At worst, it allows for an
    unpriviledged user on unpriviledged VM to carry a sucessful host-kernel
    ring 0 code injection attack.
  * The erratum is timing-dependant, easily triggered by workloads that cause
    a high number of NMIs, such as running the "perf" tool.
  * debian/control: enable buiding on x32 (closes: #777233)

amd64-microcode (2.20141028.1) unstable; urgency=medium

  * Upstream release 20141028 built from linux-firmware:
    + Updated microcode patches for family 0x15 processors
    + Added microcode patches for family 0x16 processors
  * AMD did not update the relevant microcode documentation (errata fixed,
    microcode patch levels, etc), so there is no documentation for the
    family 0x16 microcode patches, and the documentation for family 0x15 is
    stale.
  * postinst: do not update microcode on upgrades:
    Remove code that triggers a microcode update on package upgrade.  The
    resulting postinst script is now identical to the one in Debian jessie's
    intel-microcode, and thus known-good.
    NOTE: this code was already disabled for the majority of the users due
    to Debian bug #723975 (closes: #723975, #723081)
  * kpreinst: remove, we don't update microcode on postinst anymore
  * blacklist automated loading of the microcode module:
    This is in line with the desired behavior of only updating microcode
    *automatically* during system boot, when it is safer to do so.  The
    local admin can still load the microcode module and update the microcode
    manually at any time, of course.  This is in sync with the intel-microcode
    packages in Debian jessie, which will also blacklist the microcode module.
    Note that the initramfs will force-load the microcode module in a safe
    condition, the blacklist avoids module autoloading outside the initramfs
  * control: bump standards version (no changes required)
  * copyright: update upstream URL and upstream copyright date
    (closes: #753593)
  * docs: future-proof by using a glob pattern for per-family README files
  * initramfs hook: support forced installation of amd64-microcode:
    Add a config file (/etc/default/amd64-microcode) to select the mode of
    operation: do nothing, force install to initramfs, install only when
    running on an amd64 processor (closes: #726854)
  * initramfs hook: fix (likely unexploitable) issues found by shellcheck
  * Add a NEWS.Debian file to warn users we will no longer update the
    microcode on package upgrade (note that we were not doing it on any
    Debian kernels anyway).  Also document the existence of the new
    /etc/default/amd64-microcode file

amd64-microcode (2.20131007.1) unstable; urgency=low

  * New upstream release, received through linux-firmware and LKML
    + updated microcode:
      sig 0x00500F10, id 0x05000029: erratum (+) 784;
      sig 0x00500F20, id 0x05000119: erratum (+) 784;

      sig 0x00600F20, id 0x06000822: errata 691, 699, 704, 708, 709, 734,
          740, 778;
    + This update fixes important processor bugs that cause data corruption
      or unpredictable system behaviour.  It also fixes a performance issue
      and several issues that cause system lockup.
  * Switch to native package, since there is no upstream tarball

amd64-microcode (2.20120910-1) unstable; urgency=high

  * debian/control: update Breaks for new intel-microcode version scheme
  * Bump major version number, this will allow us to also update the stable
    branch of amd64-microcode in the future without clashing with the stable
    branch of intel-microcode.  The real issue is that amd64-microcode
    1.20120910-3 and intel-microcode 1.20130222.6 have changed (in lockstep)
    to a different initramfs cooperation protocol, but I failed to bump the
    major version at that time
  * Urgency high to avoid delaying a series of high-priority intel-microcode
    updates being done at the moment: we need this version in testing before
    I can upload stable backports of intel-microcode or amd64-microcode

  * initramfs, postinst: blacklist several kernel versions (Closes: #717185)
  * control: add breaks: intel-microcode (<< 1.20130222.6~)
  * load microcode module on package install/upgrade

  * initramfs: work around initramfs-tools bug #688794.
    Use "_" in place of "+-." for the initramfs script name.  This works
    around a PANIC during boot when the initramfs was created in a system
    with noexec $TMPDIR.

          734, 740;
    + This update adds critical errata fixes for commonly used features.
      The hit probability of these errata is unknown to the Debian maintainer.
  * README.Debian: mention module-init-tools, not just kmod.  This is useful
    when backporting to Debian Squeeze
  * debian/control: add Vcs-* fields
