intel-microcode (3.20161104.1~deb8u1) stable; urgency=medium
* This is the same package as 3.20161104.1 from unstable/testing and
3.20161104.1~bpo8+1, from jessie-backports.  It has been present in
unstable since 2016-11-09, testing since 2016-11-15, and jessie-backports
since 2016-11-17.
+ Supposed to fix critical Intel TSX erratum BDE85 on Xeon-D 1500 Y0
+ Known to fix critical errata on several Xeon-D 1500 models which
will crash vmware (KB2146388) and likely Linux as well
+ Fixes likely critical errata (which ones unknown) on Broadwell-E
(Core extreme edition 5th gen, Xeon E5v4, Xeon E7v4)
+ Removes (very likely outdated) microcode for the C3500 and C5500 family
of embedded Xeon (Jasper Forest).  These embedded Xeons are typically
found on (older) network equipment appliances such as firewalls/IPS/IDS,
and also on data storage devices, and thus are supposed to receive
microcode updates through their vendors

intel-microcode (3.20161104.1) unstable; urgency=medium
* New upstream microcode datafile 20161104
+ New Microcodes:
sig 0x00050663, pf_mask 0x10, 2016-10-12, rev 0x700000d, size 20480
sig 0x00050664, pf_mask 0x10, 2016-06-02, rev 0xf00000a, size 21504
+ Updated Microcodes:
sig 0x000306f2, pf_mask 0x6f, 2016-10-07, rev 0x0039, size 32768
sig 0x000406f1, pf_mask 0xef, 2016-10-07, rev 0xb00001f, size 25600
+ Removed Microcodes:
sig 0x000106e4, pf_mask 0x09, 2013-07-01, rev 0x0003, size 6144
+ This update fixes critical errata on Broadwell-DE V2/Y0 (Xeon
D-1500 family), including one that can crash VMWare ESXi 6 with
#PF (VMWare KB2146388), and could affect Linux as well.  This same
issue was fixed for the E5v4 Xeons in release 20160607
+ This update fixes undisclosed (and likely critical) errata on
Broadwell-E Core i7-68xxK/69xxK/6950X, Broadwell-EP/EX B0/R0/M0
Xeon E5v4 and Xeon E7v4, and Haswell-EP Xeon E5v3
+ This release deletes the microcode update for the Jasper Forest
embedded Xeons (Xeon EC35xx/LC35xx/EC35xx/LC55xx), for undisclosed
reasons.  The deleted microcode is outdated when compared with the
updates for the other Nehalem Xeons
* Makefile: always exclude microcode sig 0x206c2 just in case
Intel is quite clear in the Intel SA-00030 advisory text that recent
revisions (0x14 and later?) of the 0x206c2 microcode updates must be
installed along with updated SINIT ACM on vPro systems (i.e. through
an UEFI/BIOS firmware update).  This is a defensive change so that we
don't ship such a microcode update in the future by mistake
* source: remove partially superseded upstream data file: 20160714
* source: remove superseded upstream data file: 20101123
* changelog: replace "pf mask" with "pf_mask"
* control, compat: switch debhelper compatibility level to 9
* control: bump standards-version, no changes required
