[PATCH v3] recipes-core/: Disable LUV_STORAGE_URL parameter by default in luv.cfg
by Gayatri Kammela
LUV_STORAGE_URL in luv.cfg has a default value which meant to indicate
the format of the url to be given by user. However, the script that
saves and submit the results takes the default value as a parameter when
user didn't wish to use the feature.
The default value is not valid and thus it makes sense to disable this
parameter by default value "none", leaving the script run only if
user provides the url.

Changes since v2:
1) Added additional layer of logic to prevent the script from running when
there is no luv_storage parameter.
Changes since v1:
1)Modified the logic that looks for luv_storage=none instead of generic none.

[PATCH] recipes-core/udev: Remove eudev_3.2.bbappend file
by Gayatri Kammela
eudev_3.2.bbappend file is created to add runtime dependencies
that produces the udev-cache package for utils like gzip. However, we
don't need the udev-cache package anymore as it is taken care of by
systemd, thus removing the eudev_3.2.bbappend file.

Linux UEFI Validation Project v2.1-rc2 release
by Neri, Ricardo
Hello,
This is to announce the release of LUV v2.1-rc2.
It has been a while since the last time of our last release. This is not
the ideal release cadence are working to make changes. We will now
release
more frequently. We aim to release a new version every 4-5 weeks with
the
content we accumulate over that period of time.
Given the large number of new features and changes in this release, it
made sense to release it as rc2 of v2.1 to allow for issues to arise and
stabilize towards the next release cycle.
== Goodies
This release include the client side of our telemetrics solution. This
solution is based on the implementation done for Clear Linux[1]; abiding
Intel privacy policies[2]. Please note that telemetrics is an opt-in
feature and is disabled by default and only works for systems within
Intel networks. We will work now on the server side of the solution.
In this release we have migrated from systemV to systemd, which is
inline
with most Linux distributions. Also, our telemetrics client needed it
to function. Megha Dey did all the heavy lifting to migrate to systemd;
which was not an easy task (kudos to her!). She worked on stabilizing
network and revamping our splash screen, which now uses plymouth.
Sai Praneeth Prakhya extended our existing implementation to detect
illegal access to UEFI Boot Services memory regions after boot. His
extension now allows to detect such access to also conventional memory.
Likewise, it now detects these acceses at runtime and long after UEFI
SetVirtualAddressMap. This has been quite useful recently to detect bugs
related to UEFI capsules in certain firmware implementations.
Gayatri Kammela worked on providing tools to make the netboot images
more
useful. She completed a reference implementation of an HTTP server to
collect test results in a test farm. The documentation of this
implementation can be found here[2]; we don't provide collection
services.
Of course, the client-side implementation of this solution is part of
this
release. Along with this solution, she wrote a script to customize a
netboot binary (an EFI application) to work with her reference
implementation[4].
Naresh Bhat updated the kernel configuration for aarch64. He also worked
on
providing a more clean, unified and structured kernel command line for
all
the supported CPU architectures. He also enabled support of netboot
images
for aarch64.
Fathi Boudra kindly reworked the kernel configuration fragments to avoid
unnecessary duplications.
Matt Hart added a new luv.poweroff option.
Configuration of LUV has been simplified by moving all the parameters
that
the user might configure a LUV.cfg file found in the boot partition of
the
disk image. No more meddling with the grub.cfg configuration file.
We now provide images built for both GPT and MBR partition schemes.
== Updated test suites
We include FWTS V17.03.00, CHIPSEC v1.2.5 plus all the changes available
as of this week towards the release of v.1.2.6, which should be coming
soon. BITS was bumped to v2079. We use Linux v4.10. This release is
based
on the Morty version of the Yocto Project.
=== meta-oe and updates to the build proces
Our build process changed a bit. We now include certain components from
the
meta-oe layer[5]. Such layer has been added to our repository, but it
still
need to be added locally to the build/conf/bblayers.conf file when
building.
=== Binary images for x86
A announcement to download binary images for x86 will be sent this week.
== Known issues:

[PATCH V2 0/3] Reorganize and enable EFI configs
by Sai Praneeth Prakhya
From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com>
Presently, efi.cfg file is exclusive to x86 architecture, but let's make
it common across all architectures so that we could avoid duplication.
This change implies that any EFI config that is common to all the
architectures should live in efi.cfg file and any architecture specific
EFI config should live in "efi_{arch}.cfg" file specific to that
architecture.
Changes since V1:
1. Rename architecture specific efi.cfg file to efi_{arch}.cfg. Since
bitbake gets confused while appending files that have same names even
though they live in different directories.

[PATCH V2 3/3] linux-yocto-efi-test: Enable EFI_PGT_DUMP for x86
by Sai Praneeth Prakhya
From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com>
When enabled, at boot time kernel dumps "efi_pgd" (page directory to
hold efi region mappings). This is the first table to look at when
debugging any page fault related to efi regions. We can easily say why
the page fault had occurred? Is it because of a missing mapping or a
mismatch in page table attributes?
As we also have "efi=debug" command line parameter, efi_pgd will act as
a supplement to let us know why the efi region isn't mapped (if the page
fault occurred because of a missing mapping). For example, if we know
the physical address at which the page fault had occurred, using
efi_pgd we know that the region isn't mapped and from efi memory map
(printed by efi=debug) we can identify the type of memory region (like
EFI_CONVENTIONAL_MEMORY, EFI_BOOT_SERVICES_CODE/DATA, EFI_RUNTIME etc)
and thus confirm why the region isn't mapped.

[PATCH V2 2/3] linux-yocto-efi-test: Enable CONFIG_EFI_TEST for all architectures
by Sai Praneeth Prakhya
From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com>
EFI_TEST is a kernel config option used by FWTS to run efi test suites
(like uefirttime, uefiauthvar etc). This config option allows FWTS to
directly invoke efi_runtime_services() rather than kernel invoking them.
Please visit https://patchwork.kernel.org/patch/9323781/ for more
information on EFI_TEST. FWTS also ships a legacy driver used in the
absence of EFI_TEST. But we prefer EFI_TEST to legacy driver as the
former has been upstreamed and hence is closely observed by community.
FWTS is also smart enough to choose among the drivers and hence there
should not be any issues.

[PATCH V2 1/3] linux-yocto-efi-test: Make efi.cfg file common across all architectures
by Sai Praneeth Prakhya
From: Sai Praneeth <sai.praneeth.prakhya(a)intel.com>
Presently, efi.cfg file is exclusive to x86 architecture, but let's make
it common across all architectures so that we could avoid duplication.
EFI config options specific to any architecture should live in
"efi_{arch}.cfg" file specific to that architecture.
