+amd64-microcode (2.20141028.1) unstable; urgency=medium
+
+    This release drops support for automatically applying microcode updates
+    without a reboot.  The microcode updates can still be applied without a
+    reboot through manual action of the system administrator.
+
+    This is a defensive measure.  At this time, there are no reported
+    issues caused by the AMD microcode update itself when done outside of
+    the boot process.
+
+    However, updating only on boot works around a very elusive issue in
+    the Linux kernel microcode update driver for AMD processors, which
+    may or may not have been fixed in the latest stable/long-term
+    kernels.
+
+    It is now possible to configure how the amd64-microcode package should
+    behave through the /etc/default/amd64-microcode file.  By default, it
+    will install microcode update support to the initramfs only when
+    running in a system with an AMD processor.

+amd64-microcode for Debian
+--------------------------
+
+Introduction:
+
+AMD AMD64 processors are capable of field-upgrading their control program
+(microcode).  These microcode updates correct processor errata, and are
+often important for safe, correct system operation.
+
+While most of the microcode updates fix problems that happen extremely
+rarely, there are enough updates fixing issues that would cause system
+lockup, memory corruption, or unpredictable system behavior, to warrant
+taking it seriously.
+
+Microcode updates are ephemeral: they will be lost after a processor hard
+reset or after the processor is powered off.  They must be reapplied at
+every boot and after the system wakes up from suspend to RAM or disk.
+
+Updating the processor microcode is the responsibility of the system
+firmware (BIOS or EFI).  However, not all vendors will release timely
+updates for their firmware when AMD releases updated microcode, and most
+users don't update their system firmware in a timely fashion (or at all)
+anyway.
+
+The end result is that, unless some other method of distributing microcode
+updates is in place, the processor in many systems will be running with
+outdated microcode, increasing the chances of incorrect system operation.
+
+Debian can apply microcode updates to the system processors during the
+operating system boot automatically.  This requires the use of a suitably
+configured Linux kernel 3.14 or later, and an initramfs.
+
+
+Installing microcode updates:
+
+For the Debian default kernel, it is enough to install the amd64-microcode
+package as well as the initramfs-tools package and the microcode update
+will be applied automatically at the next reboot.
+
+It is also possible to use "dracut" instead of initramfs-tools, but the
+support for early microcode updates must be enabled manually in
+dracut.conf (set the option "early_microcode=yes").  Force an update of
+the initramfs using dracut, and reboot.  Note that since Linux kernel 4.4,
+one must use dracut 044 or later.
+
+Applying the microcode updates without the use of an early initramfs is
+not automatically supported anymore, due to future safety concerns.
+However, the local administrator may trigger an immediate microcode update
+attempt at any time, at her own risk:
+
+  USING AN INITRAMFS+REBOOT IS SAFER.  DO THIS ONLY WHEN YOU KNOW BETTER:
+  as root:
+  echo 1 > /sys/devices/system/cpu/microcode/reload
+
+
+RECOVERY PROCEDURE:
+
+It is possible for a microcode update to not work well, or to not work at
+all on specific system models.  This is very rare when using the safe
+microcode update procedure described above and an up-to-date Linux kernel,
+but it has happened at least once.
+
+Should you experience problems because of the microcode update, you will
+have to bypass the microcode update process that happens during operating
+system startup (boot), and remove the amd64-microcode package until the
+underlying issue is fixed.
+
+To bypass the microcode update during system startup, you must instruct the
+boot loader (grub, lilo, etc) to pass the "dis_ucode_ldr" parameter
+(without the quotes) to the kernel.
+
+If your system uses grub (the default bootloader in Debian):
+
+  1. Access the grub menu during boot (press and hold the left "Shift"
+     key right after starting the system up if you don't see a grub menu
+     during boot);
+
+  2. Move the highlight/cursor to the kernel/boot option you want to
+     use, and press the "e" key to edit it;
+
+  3. Locate the line that starts with "linux" using the cursor
+     keys.  You must add the word "dis_ucode_ldr" (without the quotes) to
+     the end of that line;
+
+  4. Press "Ctrl+X" to start (boot) the system.  The microcode updates
+     will be skipped.
+
+After the system is running, remove or purge the amd64-microcode package.
+
+If removing/purging the package doesn't do it automatically for some
+reason, refresh the initramfs using the "update-initramfs -u" command (as
+the root user), and possibly "update-initramfs -u -k <kernel version>".
+
+"dracut" users, please refer to the dracut documentation on how to update
+the initramfs images for every installed kernel.
+
+Please report any issues caused by microcode updates to the mailing-list or
+to the Debian bug tracker.

+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
