Subject: [PATCH] Add support for Linux EFI stub loading.
Also:
commit 71c843745f22f81e16d259e2e19c99bf3c1855c1
Author: Colin Watson <cjwatson@ubuntu.com>
Date: Tue Oct 23 10:40:49 2012 -0400
Don't allow insmod when secure boot is enabled.
Hi,
Fedora's patch to forbid insmod in UEFI Secure Boot environments is fine
as far as it goes. However, the insmod command is not the only way that
modules can be loaded. In particular, the 'normal' command, which
implements the usual GRUB menu and the fully-featured command prompt,
will implicitly load commands not currently loaded into memory. This
permits trivial Secure Boot violations by writing commands implementing
whatever you want to do and pointing $prefix at the malicious code.
I'm currently test-building this patch (replacing your current
grub-2.00-no-insmod-on-sb.patch), but this should be more correct. It
moves the check into grub_dl_load_file.

Subject: [PATCH] IBM client architecture (CAS) reboot support
This is an implementation of IBM client architecture (CAS) reboot for GRUB.
There are cases where the POWER firmware must reboot in order to support
specific features requested by a kernel. The kernel calls
ibm,client-architecture-support and it may either return or reboot with the new
feature set. eg:
Calling ibm,client-architecture-support.../
Elapsed time since release of system processors: 70959 mins 50 secs
Welcome to GRUB!
Instead of return to the GRUB menu, it will check if the flag for CAS reboot is
set. If so, grub will automatically boot the last booted kernel using the same
parameters

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Wed, 26 Feb 2014 21:49:12 -0500
Subject: [PATCH] Make "exit" take a return code.
This adds "exit" with a return code. With this patch, any "exit"
command /may/ include a return code, and on platforms that support
returning with an exit status, we will do so. By default we return the
same exit status we did before this patch.

Subject: [PATCH] Fix bad test on GRUB_DISABLE_SUBMENU.
The file /etc/grub.d/10_linux does
if [ "x$is_top_level" = xtrue ] && [ "x${GRUB_DISABLE_SUBMENU}" != xy ]; then
when it should do
if [ "x$is_top_level" = xtrue ] && [ "x${GRUB_DISABLE_SUBMENU}" != xtrue ]; then
which results in submenus in /boot/grub2/grub.cfg when
GRUB_DISABLE_SUBMENU="yes".

Subject: [PATCH] Add support for UEFI operating systems returned by os-prober
os-prober returns UEFI operating systems in the form:
path:long-name:name
where path is the path under the EFI directory on the ESP. This is in
contrast to legacy OSes, where path is the device string. Handle this case.

This patch makes grub look for its config file on efi where the app was
found. It was originally written by Matthew Garrett, and adapted to fix the
"No modules are loaded on grub2 network boot" issue:

Subject: [PATCH] Search for specific config file for netboot
This patch implements a search for a specific configuration when the config
file is on a remoteserver. It uses the following order:
1) DHCP client UUID option.
2) MAC address (in lower case hexadecimal with dash separators);
3) IP (in upper case hexadecimal) or IPv6;
4) The original grub.cfg file.
This procedure is similar to what is used by pxelinux and yaboot:
http://www.syslinux.org/wiki/index.php/PXELINUX#config
This should close the bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=873406

Subject: [PATCH] use fw_path prefix when fallback searching for grub config
When PXE booting via UEFI firmware, grub was searching for grub.cfg
in the fw_path directory where the grub application was found. If
that didn't exist, a fallback search would look for config file names
based on MAC and IP address. However, the search would look in the
prefix directory which may not be the same fw_path. This patch
changes that behavior to use the fw_path directory for the fallback
search. Only if fw_path is NULL will the prefix directory be searched.

This is adapted from the patch at
https://bugzilla.redhat.com/show_bug.cgi?id=1019660 , which is against
the now very old version of convert_system_partition_to_system_disk().
As such, it certainly not the right thing for upstream, but should
function for now.

/boot/efi/EFI/fedora/grubenv even though they're different mount points,
which allows /usr/bin/grub2-editenv to be the same across platforms
(i.e. UEFI vs BIOS).

Then follow instructions printed out by grub-mknetdir on configuring your DHCP
server.
+The grub.cfg file is placed in the same directory as the path output by
+grub-mknetdir hereafter referred to as FWPATH. GRUB will search for its
+configuration files in order using the following rules where the appended
+value corresponds to a value on the client machine.
+
+@example
+@group
+@samp{(FWPATH)}/grub.cfg-@samp{(UUID OF NIC)}
+@samp{(FWPATH)}/grub.cfg-@samp{(MAC ADDRESS OF NIC)}
+@samp{(FWPATH)}/grub.cfg-@samp{(IPv4 OR IPv6 ADDRESS)}
+@samp{(FWPATH)}/grub.cfg
+@end group
+@end example
+
+The client will only attempt to look up an IPv6 address config once, however,
+it will try the IPv4 multiple times. The concrete example below shows what
+would happen under the IPv4 case.
+
+@example
+@group
+UUID: 7726a678-7fc0-4853-a4f6-c85ac36a120a
+MAC: 52:54:00:ec:33:81
+IPV4: 10.0.0.130 (0A000082)
+@end group
+@end example
+
+@example
+@group
+@samp{(FWPATH)}/grub.cfg-7726a678-7fc0-4853-a4f6-c85ac36a120a
+@samp{(FWPATH)}/grub.cfg-52-54-00-ec-33-81
+@samp{(FWPATH)}/grub.cfg-0A000082
+@samp{(FWPATH)}/grub.cfg-0A00008
+@samp{(FWPATH)}/grub.cfg-0A0000
+@samp{(FWPATH)}/grub.cfg-0A000
+@samp{(FWPATH)}/grub.cfg-0A00

+@samp{(FWPATH)}/grub.cfg-0A
+@samp{(FWPATH)}/grub.cfg-0
+@samp{(FWPATH)}/grub.cfg
+@end group
+@end example
+
After GRUB has started, files on the TFTP server will be accessible via the
@samp{(tftp)} device.

Subject: [PATCH] Use Distribution Package Sort for grub2-mkconfig (#1124074)
Users reported that newly installed kernels on their systems installed
with grub-mkconfig would not appear on the grub boot list in order
starting with the most recent. Added an option for rpm-based systems to
use the rpm-sort library to sort kernels instead.

Apparently the test for whether to use grub-rpm-sort and also the
renaming of it to grub2-rpm-sort on the runtime side weren't right.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Josef Bacik <jbacik@fb.com>
Date: Wed, 12 Aug 2015 08:57:55 -0700
Subject: [PATCH] tcp: add window scaling support
Sometimes we have to provision boxes across regions, such as California to
Sweden. The http server has a 10 minute timeout, so if we can't get our 250mb
image transferred fast enough our provisioning fails, which is not ideal. So
add tcp window scaling on open connections and set the window size to 1mb. With
this change we're able to get higher sustained transfers between regions and can
transfer our image in well below 10 minutes. Without this patch we'd time out
every time halfway through the transfer. Thanks,

section that reads the user.cfg file which contains a user set GRUB
password. Users in that scenario will now be warned that grub-mkconfig
must be run prior to their newly set password taking effect.

Subject: [PATCH] Clean up grub-setpassword documentation (#1290799)
The output for --help had some errors. Corrected those and polished the
text to be a little easier to follow. Carried verbage over to man page
to maintain internal consistency.

A shell substitution was expecting non-translated output to grab the
hashed password and put it in the user.cfg file. Modified code to force
the generic C locale when this particular piece of code is run.

Subject: [PATCH] Revert "reopen SNP protocol for exclusive use by grub"
I *think* this should have been replaced by upstream's
49426e9fd2e562c73a4f1206f32eff9e424a1a73, so I'm reverting for now.
May resolve rhbz#1273974.
This reverts commit 147daeab22db793978f952b6f0d832919a1b0081.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Thu, 23 Jun 2016 11:01:39 -0400
Subject: [PATCH] Add grub-get-kernel-settings and use it in 10_linux
This patch adds grub-get-kernel-settings, which reads the system kernel
installation configuration from /etc/sysconfig/kernel, and outputs
${GRUB_...} variables suitable for evaluation by grub-mkconfig. Those
variables are then used by 10_linux to choose whether or not to create
debug stanzas.
Resolves: rhbz#1226325

Subject: [PATCH] Normalize slashes in tftp paths.
Some tftp servers do not handle multiple consecutive slashes correctly;
this patch avoids sending tftp requests with non-normalized paths.

Subject: [PATCH] Fix malformed tftp packets
0088-Normalize-slashes-in-tftp-paths.patch collapses multiple contiguous
slashes in a filename into one slash in the tftp packet filename field.
However, the packet buffer pointer is advanced using the original name.
This leaves unitialized data between the name field and the type field
leading to tftp errors. Use the length of the normalized name to avoid
this.

Subject: [PATCH] bz1374141 fix incorrect mask for ppc64
The netmask configured in firmware is not respected on ppc64 (big endian).
When 255.255.252.0 is set as netmask in firmware, the following is the value of bootpath string in grub_ieee1275_parse_bootpath().
/vdevice/l-lan@30000002:speed=auto,duplex=auto,192.168.88.10,,192.168.89.113,192.168.88.1,5,5,255.255.252.0,512
The netmask in this bootpath is no problem, since it's a value specified in firmware. But,
The value of 'subnet_mask.ipv4' was set with 0xfffffc00, and __builtin_ctz (~grub_le_to_cpu32 (subnet_mask.ipv4)) returned 16 (not 22).
As a result, 16 was used for netmask wrongly.
1111 1111 1111 1111 1111 1100 0000 0000 # subnet_mask.ipv4 (=0xfffffc00)
0000 0000 1111 1100 1111 1111 1111 1111 # grub_le_to_cpu32 (subnet_mask.ipv4)
1111 1111 0000 0011 0000 0000 0000 0000 # ~grub_le_to_cpu32 (subnet_mask.ipv4)
And, the count of zero with __builtin_ctz can be 16.
This patch changes it as below.
1111 1111 1111 1111 1111 1100 0000 0000 # subnet_mask.ipv4 (=0xfffffc00)
0000 0000 1111 1100 1111 1111 1111 1111 # grub_le_to_cpu32 (subnet_mask.ipv4)
1111 1111 1111 1111 1111 1100 0000 0000 # grub_swap_bytes32(grub_le_to_cpu32 (subnet_mask.ipv4))
0000 0000 0000 0000 0000 0011 1111 1111 # ~grub_swap_bytes32(grub_le_to_cpu32 (subnet_mask.ipv4))
The count of zero with __builtin_clz can be 22. (clz counts the number of one bits preceding the most significant zero bit)

Subject: [PATCH] arm64: make sure fdt has #address-cells and #size-cells
properties
Recent upstream changes to kexec-tools relies on #address-cells
and #size-cells properties in the FDT. If grub2 needs to create

In that case, set #address-cells and #size-cells properties to

Subject: [PATCH] macos: just build chainloader entries, don't try any xnu xnu.
Since our bugs tell us that the xnu boot entries really just don't work
most of the time, and they create piles of extra boot entries, because
they can't quite figure out 32-vs-64 and other stuff like that.
It's rediculous, and we should just boot their bootloader through the
chainloader instead.
So this patch does that.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Jeff Mahoney <jeffm@suse.com>
Date: Wed, 18 Dec 2013 09:57:04 +0000
Subject: [PATCH] grub2/btrfs: Add ability to boot from subvolumes
This patch adds the ability to specify a different root on a btrfs
filesystem too boot from other than the default one.
btrfs-list-snapshots <dev> will list the subvolumes available on the
filesystem.
set btrfs_subvol=<path> and set btrfs_subvolid=<subvolid> will specify
which subvolume to use and any pathnames provided with either of those
variables set will start using that root. If the subvolume or subvolume id
doesn't exist, then an error case will result.
It is possible to boot into a separate GRUB instance by exporting the
variable and loading the config file from the subvolume.

Subject: [PATCH] No more "Bootable Snapshot" submenu in grub.cfg.
This breaks grubby (run on kernel upgrades) because grubby just

Subject: [PATCH] Use grub_efi_...() memory helpers where reasonable.
This uses grub_efi_allocate_pool(), grub_efi_free_pool(), and
grub_efi_free_pages() instead of open-coded efi_call_N() calls, so we
get more reasonable type checking.
