All,

this is supposed to go out in about 3 weeks time. Please point out backport
candidates you find missing from its staging branch, but which you consider
relevant.

Ian, that's one for you, unless you tell me to take it.

Stewart - it would have been helpful if you also included the title
(and instead perhaps just an abbreviated hash). This way I
needed to first look it up to tell whether it falls in Ian's or my court.

Thanks, Jan

Indeed.  I've committed it.

Thanks,
Ian.

Marek's patches below are each straightforward and enable clean builds with
newer gcc.

fa7789e : tools/libxc: fix strncpy size
27751d8 : tools/misc: fix hypothetical buffer overflow in xen-lowmemd
938c8f5 : tools/xenpmd: fix possible '\0' truncation
7f601f7 : tools/gdbsx: fix -Wstringop-truncation warning
437e00f : tools/kdd: mute spurious gcc warning
2de2b10 : tools/kdd: alternative way of muting spurious gcc warning
3a633c2 : tools/blktap2: fix hypothetical buffer overflow
850e89b : tools/blktap2: fix possible '\0' truncation

This additional patch that I just posted is probably too new for
consideration for this, but it fixes a build warning with gcc 8.1:

https://lists.xenproject.org/archives/html/xen-devel/2018-07/msg01718.html
 : tools/xentop : replace use of deprecated vwprintw

so maybe not for this one, but perhaps the next.

The full set above passed compile test for x86-64, applied on top of
current staging-4.9.

Ian, you'll be the one to decide whether to take any or all of these.

4.10.2 preparations

[Jan Beulich]

All,

strictly speaking this is supposed to go out in about a weeks time. With
4.9.3 blocked by an osstest failure, I'm now intending to cut both stable
versions at the same time. Since from my preliminary analysis it is only
a matter of time for other stable branches to also get stuck this same
way, I'm in particular not meaning for 4.10.2 to go out earlier than
4.9.3, i.e. not before that osstest issue is under control.

Please point out backport candidates you find missing from its staging
branch, but which you consider relevant. I have a few more commits
queued already for backporting:

48dbb2dbe9 x86/vmx: Avoid hitting BUG_ON() after EPTP-related domain_crash()
b6f43c14ce x86/vlapic: Bugfixes and improvements to vlapic_{read,write}()
60a56dc006 x86/hvm/ioreq: MMIO range checking completely ignores direction flag
3e4ec07e14 x86/setup: Avoid OoB E820 lookup when calculating the L1TF safe address
0fb0de8b24 x86/HVM: correct an inverted check in hvm_load()
ad0a9f273d rangeset: make inquiry functions tolerate NULL inputs
fd07b6648c VT-d/dmar: iommu mem leak fix

Therefore there's no need to request any of those explicitly.

Jan
