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.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Matthew Garrett <mjg59@coreos.com>
Date: Sun, 9 Aug 2015 16:12:39 -0700
Subject: [PATCH] Rework linux command
We want a single buffer that contains the entire kernel image in order to
perform a TPM measurement. Allocate one and copy the entire kernel into it
before pulling out the individual blocks later on.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Matthew Garrett <mjg59@coreos.com>
Date: Sun, 9 Aug 2015 16:20:58 -0700
Subject: [PATCH] Rework linux16 command
We want a single buffer that contains the entire kernel image in order to
perform a TPM measurement. Allocate one and copy the entire kernel int it
before pulling out the individual blocks later on.

Subject: [PATCH] Make any of the loaders that link in efi mode honor secure
boot.
And in this case "honor" means "even if somebody does link this in, they
won't register commands if SB is enabled."

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>

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] 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.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Robert Marshall <rmarshall@redhat.com>
Date: Mon, 16 Mar 2015 14:14:19 -0400
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.

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,

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] 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] 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: Tue, 9 Jul 2019 13:39:45 +0200
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] 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.

always make the wrong decision.

Subject: [PATCH] Make pmtimer tsc calibration not take 51 seconds to fail.
On my laptop running at 2.4GHz, if I run a VM where tsc calibration
using pmtimer will fail presuming a broken pmtimer, it takes ~51 seconds
to do so (as measured with the stopwatch on my phone), with a tsc delta
of 0x1cd1c85300, or around 125 billion cycles.
If instead of trying to wait for 5-200ms to show up on the pmtimer, we try
to wait for 5-200us, it decides it's broken in ~0x2626aa0 TSCs, aka ~2.4
million cycles, or more or less instantly.
Additionally, this reading the pmtimer was returning 0xffffffff anyway,
and that's obviously an invalid return. I've added a check for that and
0 so we don't bother waiting for the test if what we're seeing is dead
pins with no response at all.
If "debug" is includes "pmtimer", you will see one of the following
three outcomes. If pmtimer gives all 0 or all 1 bits, you will see:
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 1
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 2
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 3
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 4
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 5
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 6
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 7
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 8
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 9
kern/i386/tsc_pmtimer.c:77: pmtimer: 0xffffff bad_reads: 10
kern/i386/tsc_pmtimer.c:78: timer is broken; giving up.
This outcome was tested using qemu+kvm with UEFI (OVMF) firmware and
these options: -machine pc-q35-2.10 -cpu Broadwell-noTSX
If pmtimer gives any other bit patterns but is not actually marching
forward fast enough to use for clock calibration, you will see:
kern/i386/tsc_pmtimer.c:121: pmtimer delta is 0x0 (1904 iterations)
kern/i386/tsc_pmtimer.c:124: tsc delta is implausible: 0x2626aa0
This outcome was tested using grub compiled with GRUB_PMTIMER_IGNORE_BAD_READS
defined (so as not to trip the bad read test) using qemu+kvm with UEFI
(OVMF) firmware, and these options: -machine pc-q35-2.10 -cpu Broadwell-noTSX
If pmtimer actually works, you'll see something like:
kern/i386/tsc_pmtimer.c:121: pmtimer delta is 0x0 (1904 iterations)
kern/i386/tsc_pmtimer.c:124: tsc delta is implausible: 0x2626aa0
This outcome was tested using qemu+kvm with UEFI (OVMF) firmware, and
these options: -machine pc-i440fx-2.4 -cpu Broadwell-noTSX
I've also tested this outcome on a real Intel Xeon E3-1275v3 on an Intel
Server Board S1200V3RPS using the SDV.RP.B8 "Release" build here:

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add BLS support to grub-mkconfig
GRUB now has BootLoaderSpec support, the user can choose to use this by
setting GRUB_ENABLE_BLSCFG to true in /etc/default/grub. On this setup,
the boot menu entries are not added to the grub.cfg, instead BLS config
files are parsed by blscfg command and the entries created dynamically.
A 10_linux_bls grub.d snippet to generate menu entries from BLS files
is also added that can be used on platforms where the bootloader doesn't
have BLS support and only can parse a normal grub configuration file.
Portions of the 10_linux_bls were taken from the ostree-grub-generator
script that's included in the OSTree project.
Fixes to support multi-devices and generate a BLS section even if no
kernels are found in the boot directory were proposed by Yclept Nemo
and Tom Gundersen respectively.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Make a "gdb" dprintf that tells us load addresses.
This makes a grub_dprintf() call during platform init and during module
loading that tells us the virtual addresses of the .text and .data
sections of grub-core/kernel.exec and any modules it loads.
Specifically, it displays them in the gdb "add-symbol-file" syntax, with
the presumption that there's a variable $grubdir that reflects the path
to any such binaries.

Subject: [PATCH] Don't attempt to export the start and _start symbols for
grub-emu
Commit 318ee04aadc ("make better backtraces") reworked the backtrace logic
but the changes lead to the following build error on the grub-emu platform:
grub_emu_lite-symlist.o:(.data+0xf08): undefined reference to `start'
collect2: error: ld returned 1 exit status
make[3]: *** [Makefile:25959: grub-emu-lite] Error 1
make[3]: *** Waiting for unfinished jobs....
cat kernel_syms.input | grep -v '^#' | sed -n \
-e '/EXPORT_FUNC *([a-zA-Z0-9_]*)/{s/.*EXPORT_FUNC *(\([a-zA-Z0-9_]*\)).*/defined kernel '""'\1/;p;}' \
-e '/EXPORT_VAR *([a-zA-Z0-9_]*)/{s/.*EXPORT_VAR *(\([a-zA-Z0-9_]*\)).*/defined kernel '""'\1/;p;}' \
| sort -u >kernel_syms.lst
The problem is that start and _start symbols are exported unconditionally,
but these aren't defined for grub-emu since is an emultaed platform so it
doesn't have a startup logic. Don't attempt to export those for grub-emu.

Subject: [PATCH] Add support for non-Ethernet network cards
This patch replaces fixed 6-byte link layer address with
up to 32-byte variable sized address.
This allows supporting Infiniband and Omni-Path fabric
which use 20-byte address, but other network card types
can also take advantage of this change.
The network card driver is responsible for replacing L2
header provided by grub2 if needed.
This approach is compatible with UEFI network stack which
also allows up to 32-byte variable size link address.
The BOOTP/DHCP packet format is limited to 16 byte client
hardware address, if link address is more that 16-bytes
then chaddr field in BOOTP it will be set to 0 as per rfc4390.

Subject: [PATCH] efinet: UEFI IPv6 PXE support
When grub2 image is booted from UEFI IPv6 PXE, the DHCPv6 Reply packet is
cached in firmware buffer which can be obtained by PXE Base Code protocol. The
network interface can be setup through the parameters in that obtained packet.

Subject: [PATCH] bootp: Add processing DHCPACK packet from HTTP Boot
The vendor class identifier with the string "HTTPClient" is used to denote the
packet as responding to HTTP boot request. In DHCP4 config, the filename for
HTTP boot is the URL of the boot file while for PXE boot it is the path to the
boot file. As a consequence, the next-server becomes obseleted because the HTTP
URL already contains the server address for the boot file. For DHCP6 config,
there's no difference definition in existing config as dhcp6.bootfile-url can
be used to specify URL for both HTTP and PXE boot file.
This patch adds processing for "HTTPClient" vendor class identifier in DHCPACK
packet by treating it as HTTP format, not as the PXE format.

Subject: [PATCH] efinet: Setting network from UEFI device path
The PXE Base Code protocol used to obtain cached PXE DHCPACK packet is no
longer provided for HTTP Boot. Instead, we have to get the HTTP boot
information from the device path nodes defined in following UEFI Specification
sections.
9.3.5.12 IPv4 Device Path
9.3.5.13 IPv6 Device Path
9.3.5.23 Uniform Resource Identifiers (URI) Device Path
This patch basically does:
include/grub/efi/api.h:
Add new structure of Uniform Resource Identifiers (URI) Device Path
grub-core/net/drivers/efi/efinet.c:
Check if PXE Base Code is available, if not it will try to obtain the netboot
information from the device path where the image booted from. The DHCPACK
packet is recoverd from the information in device patch and feed into the same
DHCP packet processing functions to ensure the network interface is setting up
the same way it used to be.

Subject: [PATCH] efinet: Setting DNS server from UEFI protocol
In the URI device path node, any name rahter than address can be used for
looking up the resources so that DNS service become needed to get answer of the
name's address. Unfortunately the DNS is not defined in any of the device path
nodes so that we use the EFI_IP4_CONFIG2_PROTOCOL and EFI_IP6_CONFIG_PROTOCOL
to obtain it.
These two protcols are defined the sections of UEFI specification.
27.5 EFI IPv4 Configuration II Protocol
27.7 EFI IPv6 Configuration Protocol
include/grub/efi/api.h:
Add new structure and protocol UUID of EFI_IP4_CONFIG2_PROTOCOL and
EFI_IP6_CONFIG_PROTOCOL.
grub-core/net/drivers/efi/efinet.c:
Use the EFI_IP4_CONFIG2_PROTOCOL and EFI_IP6_CONFIG_PROTOCOL to obtain the list
of DNS server address for IPv4 and IPv6 respectively. The address of DNS
servers is structured into DHCPACK packet and feed into the same DHCP packet
processing functions to ensure the network interface is setting up the same way
it used to be.

Subject: [PATCH] AUDIT-0: http boot tracker bug
Fixing a memory leak in case of error, and a integer overflow, leading to a
heap overflow due to overly large chunk sizes.
We need to check against some maximum value, otherwise values like 0xffffffff
will eventually lead in the allocation functions to small sized buffers, since
the len is rounded up to the next reasonable alignment. The following memcpy
will then smash the heap, leading to RCE.
This is no big issue for pure http boot, since its going to execute an
untrusted kernel anyway, but it will break trusted boot scenarios, where only
signed code is allowed to be executed.

Subject: [PATCH] grub-editenv: Add "incr" command to increment integer value
env. variables
To be able to automatically detect if the last boot was successful,
We want to keep count of succesful / failed boots in some integer
environment variable.
This commit adds a grub-editenvt "incr" command to increment such
integer value env. variables by 1 for use from various boot scripts.

Subject: [PATCH] Add auto-hide menu support
On single-os systems we do not want to show the menu, unless something
went wrong with the previous boot, in which case the user may need the
menu to debug/fix the problem.
This commit adds a new grub.d/00_menu_auto_hide file which emits a
config snippet implementing this. I've chosen to do this in a separate
grub.d file because chances of this going upstream are small and this way
it will be easier to rebase.
Since auto-hiding the menu requires detecting the previous boot was ok,
we get fastboot support (where we don't check for a key at all) for free
so this commit also adds support for this.
The new config-file code uses the following variables:
menu_auto_hide Set this to "1" to activate the new auto-hide feature
Set this to "2" to auto-hide the menu even when multiple
operating systems are installed. Note the menu will still
auto show after booting an other os as that won't set
boot_success.
menu_show_once Set this to "1" to force showing the menu once.
boot_success The OS sets this to "1" to indicate a successful boot.
boot_indeterminate The OS increments this integer when rebooting after e.g.
installing updates or a selinux relabel.
fastboot If set to "1" and the conditions for auto-hiding the menu
are met, the menu is not shown and all checks for keypresses
are skipped, booting the default immediately.
30_os-prober.in changes somewhat inspired by:

Changes in v2:
-Drop shutdown_success tests, there is no meaningful way for systemd to set
this flag (by the time it knows all filesystems are unmounted or read-only
-Drop fwsetup_once support, systemd already supports booting directly into
the fwsetup by doing "systemctl reboot --firmware"
