From 47eddcfc6859f269bb3cfaf95d5b33502cafd9ec Mon Sep 17 00:00:00 2001
From: Michael Chang <mchang@suse.com>

Subject: [PATCH] 30_uefi-firmware: fix printf format with null byte
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On a Raspberry Pi 4, the OsIndications variable is set as following
$ od -An -t u1 /sys/firmware/efi/efivars/OsIndicationsSupported-8be4df61-93ca-11d2-aa0d-00e098032b8c
6 0 0 0 0 0 0 0 0 0 0 0
The fifth byte indicates there's no boot to uefi firmware support as no
bit is set. However the /etc/grub.d/30_uefi-firmware mistakenly detects
that from the grub-mkconfig output.
/etc/grub.d/30_uefi-firmware: line 34: warning: command substitution: ignored null byte in input
Adding boot menu entry for UEFI Firmware Settings ...
The warning has dictated that the null byte is ignored from the printf
input arguments so that the expression of
rintf 0x%x \'"$(cat $OS_INDICATIONS | cut -b5)"\')
becomes
printf 0x%x \'""\'
0x27
The numeric value of trailing character \' is outputted instead of the
null byte.
From the printf manual, there's description to the synax of formatting
the numeric value ouput of a character.
"If the leading character of a numeric argument is ‘"’ or ‘'’ then its
value is the numeric value of the immediately following character. Any
remaining characters are silently ignored if the POSIXLY_CORRECT
environment variable is set; otherwise, a warning is printed. For
example, ‘printf "%d" "'a"’ outputs ‘97’ on hosts that use the ASCII
character set, since ‘a’ has the numeric value 97 in ASCII."
From the descrption the trailing \' appears to be superfluous and should
get removed to have correct output.
printf 0x%x \'""
0x0
In additon to suppress the warning message of ignored null byte in
input, we can delete it so an empty string is used.
To illustrate the problem using echo as example
printf 0x%x \'"$(echo -e '\x00')"
-bash: warning: command substitution: ignored null byte in input
0x0
And here using tr to delete the null character
printf 0x%x \'"$(echo -e '\x00'| tr -d '\000')"
The expression above is substituted to
printf 0x%x \'""
0x0

Subject: [PATCH 1/9] Add support for Linux EFI stub loading on aarch64.
Add support for Linux EFI stub loading on aarch64.
v1:
Make efi handoff the default loader for arm64 platform.
v2:
The efi shim_lock verifier has been moved to grub core so local
shim_lock protocol is no longer needed here for aarch64 efi to verify
the loaded kernel image. From now on the framework will take care the
verificaion, consolidating the integration of various security verifiers
like secure boot, gpg and tpm.

Subject: [PATCH 1/2] Warn if MBR gap is small and user uses advanced modules
We don't want to support small MBR gap in pair with anything but
the simplest config of biosdisk+part_msdos+simple filesystem. In this
path "simple filesystems" are all current filesystems except zfs and
btrfs.

Subject: [PATCH 01/46] include/grub/i386/linux.h: Include missing
<grub/types.h> header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This header uses types defined in <grub/types.h> but does not include it,
which leads to compile errors like the following:

Subject: [PATCH] kern/efi/sb: Add chainloaded image as shim's verifiable
object
While attempting to dual boot Microsoft Windows with UEFI chainloader,
it failed with below error when UEFI Secure Boot was enabled:
error ../../grub-core/kern/verifiers.c:119:verification requested but
nobody cares: /EFI/Microsoft/Boot/bootmgfw.efi.
It is a regression, as previously it worked without any problem.
It turns out chainloading PE image has been locked down by commit
578c95298 (kern: Add lockdown support). However, we should consider it
as verifiable object by shim to allow booting in UEFI Secure Boot mode.
The chainloaded PE image could also have trusted signature created by
vendor with their pubkey cert in db. For that matters it's usage should
not be locked down under UEFI Secure Boot, and instead shim should be
allowed to validate a PE binary signature before running it.
Fixes: 578c95298 (kern: Add lockdown support)

Subject: [PATCH 1/2] mdraid1x_linux: Fix gcc10 error -Werror=array-bounds
We bumped into the build error while testing gcc-10 pre-release.
../../grub-core/disk/mdraid1x_linux.c: In function 'grub_mdraid_detect':
../../grub-core/disk/mdraid1x_linux.c:181:15: error: array subscript <unknown> is outside array bounds of 'grub_uint16_t[0]' {aka 'short unsigned int[0]'} [-Werror=array-bounds]
181 | (char *) &sb.dev_roles[grub_le_to_cpu32 (sb.dev_number)]
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../../grub-core/disk/mdraid1x_linux.c:98:17: note: while referencing 'dev_roles'
98 | grub_uint16_t dev_roles[0]; /* Role in array, or 0xffff for a spare, or 0xfffe for faulty. */
| ^~~~~~~~~
../../grub-core/disk/mdraid1x_linux.c:127:33: note: defined here 'sb'
127 | struct grub_raid_super_1x sb;
| ^~
cc1: all warnings being treated as errors
Apparently gcc issues the warning when trying to access sb.dev_roles
array's member, since it is a zero length array as the last element of
struct grub_raid_super_1x that is allocated sparsely without extra
chunks for the trailing bits, so the warning looks legitimate in this
regard.
As the whole thing here is doing offset computation, it is undue to use
syntax that would imply array member access then take address from it
later. Instead we could accomplish the same thing through basic array
pointer arithmetic to pacify the warning.

From aa096037ae013c553acf52f9e3aa3a49c91f3c57 Mon Sep 17 00:00:00 2001

Subject: [PATCH] normal: Move common datetime functions out of the normal
module
The common datetime helper functions are currently included in the normal
module, but this makes any other module that calls these functions to have
a dependency with the normal module only for this reason.
Since the normal module does a lot of stuff, it calls functions from other
modules. But since other modules may depend on it for calling the datetime
helpers, this could lead to circular dependencies between modules.
As an example, when platform == xen the grub_get_datetime() function from
the datetime module calls to the grub_unixtime2datetime() helper function
from the normal module. Which leads to the following module dependency:
datetime -> normal
and send_dhcp_packet() from the net module calls the grub_get_datetime()
function, which leads to the following module dependency:
net -> datetime -> normal
but that means that the normal module is not allowed to depend on net or
any other module that depends on it due the transitive dependency caused
by datetime. A recent patch attempted to add support to fetch the config
file over the network, which leads to the following circular dependency:
normal -> net -> datetime -> normal
So having the datetime helpers in the normal module makes it quite fragile
and easy to add circular dependencies like these, that break the build due
the genmoddep.awk script catching the issues.
Fix this by taking the datetime helper functions out of the normal module
and instead add them to the datetime module itself. Besides fixing these
issues, it makes more sense to have these helper functions there anyways.

Subject: [PATCH EMBARGOED CVE-2020-10713] yylex: Make lexer fatal errors
actually be fatal
When presented with a command that can't be tokenized to anything
smaller than YYLMAX characters, the parser calls YY_FATAL_ERROR(errmsg),
expecting that will stop further processing, as such:
#define YY_DO_BEFORE_ACTION \
yyg->yytext_ptr = yy_bp; \
yyleng = (int) (yy_cp - yy_bp); \
yyg->yy_hold_char = *yy_cp; \
*yy_cp = '\0'; \
if ( yyleng >= YYLMAX ) \
YY_FATAL_ERROR( "token too large, exceeds YYLMAX" ); \
yy_flex_strncpy( yytext, yyg->yytext_ptr, yyleng + 1 , yyscanner); \
yyg->yy_c_buf_p = yy_cp;
The code flex generates expects that YY_FATAL_ERROR() will either return
for it or do some form of longjmp(), or handle the error in some way at
least, and so the strncpy() call isn't in an "else" clause, and thus if
YY_FATAL_ERROR() is *not* actually fatal, it does the call with the
questionable limit, and predictable results ensue.
Unfortunately, our implementation of YY_FATAL_ERROR() is:
#define YY_FATAL_ERROR(msg) \
do { \
grub_printf (_("fatal error: %s\n"), _(msg)); \
} while (0)
The same pattern exists in yyless(), and similar problems exist in users
of YY_INPUT(), several places in the main parsing loop,
yy_get_next_buffer(), yy_load_buffer_state(), yyensure_buffer_stack,
yy_scan_buffer(), etc.
All of these callers expect YY_FATAL_ERROR() to actually be fatal, and
the things they do if it returns after calling it are wildly unsafe.

Subject: [PATCH 2/2] grub-install: Avoid incompleted install on i386-pc
If any error happens between grub_install_copy_files() and
grub_util_bios_setup(), the system would become unbootable with error
like undefined symbol as a result of incompleted install that leaves
behind images on disk from different build to the modules on /boot.
This patch makes grub_install_copy_files() an adjecent call to
grub_util_bios_setup() to minimize the risk of running into any error in
between that would abort the process.
V1:
* Create platform directory, /boot/grub2/i386-pc, which is required to
have existed in the process of setting up prefix for the core.img.
This fixed "failed to get canonical path of `/boot/grub2/i386-pc`"
error during grub-install.
V2: Do not clean up core.img and boot.img in i386-pc platform directory.
The core.img is required by blocklist install that will load it from
platform directory. Both files can be used by grub2-bios-setup to
reinstall images to disk made by previous grub2-install.

Subject: [PATCH] kern: Add %X option to printf functions
The printf(3) function has support for the %X format specifier, to output
an unsigned hexadecimal integer in uppercase.
This can be achived in GRUB using the %x format specifier in grub_printf()
and calling grub_toupper(), but it is more convenient if there is support
for %X in grub_printf().

Subject: [PATCH 2/7] safemath: Add some arithmetic primitives that check for
overflow
This adds a new header, include/grub/safemath.h, that includes easy to
use wrappers for __builtin_{add,sub,mul}_overflow() declared like:
bool OP(a, b, res)
where OP is grub_add, grub_sub or grub_mul. OP() returns true in the
case where the operation would overflow and res is not modified.
Otherwise, false is returned and the operation is executed.
These arithmetic primitives require newer compiler versions. So, bump
these requirements in the INSTALL file too.

Here I'd like to quote from the gcc document [1] which seems best to
explain what is going on here.
"Although the size of a zero-length array is zero, an array member of
this kind may increase the size of the enclosing type as a result of
tail padding. The offset of a zero-length array member from the
beginning of the enclosing structure is the same as the offset of an
array with one or more elements of the same type. The alignment of a
zero-length array is the same as the alignment of its elements.
Declaring zero-length arrays in other contexts, including as interior
members of structure objects or as non-member objects, is discouraged.
Accessing elements of zero-length arrays declared in such contexts is
undefined and may be diagnosed."
The l_hash[0] is apparnetly an interior member to the enclosed structure
while l_entries[0] is the trailing member. And the offending code tries
to access members in l_hash[0] array that triggers the diagnose.
Given that the l_entries[0] is used to get proper alignment to access
leaf chunks, we can accomplish the same thing through the ALIGN_UP macro
thus eliminating l_entries[0] from the structure. In this way we can
pacify the warning as l_hash[0] now becomes the last member to the
enclosed structure.

Subject: [PATCH 3/7] calloc: Make sure we always have an overflow-checking
calloc() available
This tries to make sure that everywhere in this source tree, we always have
an appropriate version of calloc() (i.e. grub_calloc(), xcalloc(), etc.)
available, and that they all safely check for overflow and return NULL when
it would occur.

From cb2f15c544895e1f3d540dd39d36c4611bdf5b7b Mon Sep 17 00:00:00 2001
From: Paulo Flabiano Smorigo <pfsmorigo@br.ibm.com>
Date: Wed, 22 Jan 2020 12:01:55 +0100
Subject: [PATCH] normal/main: Search for specific config files 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
It is enabled by default but can be disabled by setting the environment
variable "feature_net_search_cfg" to "n" in an embedded configuration.
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=873406

The kernel in front of me (slightly edited to make objdump work) looks like:

*
(I don't know why the MZ header is there 7 times, but the offsets work out, so
it's merely a surprising distraction.)
If linux_arm_kernel_header.reserved2 is 16 bytes, that means hdr_offset is
here:
00000030 01 02 03 04 45 45 45 45 74 a2 00 00 40 00 00 00 |....EEEEt...@...|
00000040 50 45 00 00 4c 01 04 00 00 00 00 00 00 00 00 00 |PE..L...........|
^^^^^^^^^^^
But it's supposed to be 4 bytes before that.
This patch makes the reserved field be 3*32 instead of 4*32, and that means we
can find the PE header correcrtly at 0x40 by reading the value at 0x3c.

Subject: [PATCH 06/46] efi: Only register shim_lock verifier if shim_lock
protocol is found and SB enabled
The shim_lock module registers a verifier to call shim's verify, but the
handler is registered even when the shim_lock protocol was not installed.
This doesn't cause a NULL pointer dereference in shim_lock_write() because
the shim_lock_init() function just returns GRUB_ERR_NONE if sl isn't set.
But in that case there's no point to even register the shim_lock verifier
since won't do anything. Additionally, it is only useful when Secure Boot
is enabled.
Finally, don't assume that the shim_lock protocol will always be present
when the shim_lock_write() function is called, and check for it on every
call to this function.

The GRUB font file can have one NAME section only. Though if somebody
crafts a broken font file with many NAME sections and loads it then the
GRUB leaks memory. So, prevent against that by loading first NAME
section and failing in controlled way on following one.

Subject: [PATCH 08/46] efi: Move the shim_lock verifier to the GRUB core
Move the shim_lock verifier from its own module into the core image. The
Secure Boot lockdown mechanism has the intent to prevent the load of any
unsigned code or binary when Secure Boot is enabled.
The reason is that GRUB must be able to prevent executing untrusted code
if UEFI Secure Boot is enabled, without depending on external modules.

Subject: [PATCH 09/46] kern: Add lockdown support
When the GRUB starts on a secure boot platform, some commands can be
used to subvert the protections provided by the verification mechanism and
could lead to booting untrusted system.
To prevent that situation, allow GRUB to be locked down. That way the code
may check if GRUB has been locked down and further restrict the commands
that are registered or what subset of their functionality could be used.
The lockdown support adds the following components:
* The grub_lockdown() function which can be used to lockdown GRUB if,
e.g., UEFI Secure Boot is enabled.
* The grub_is_lockdown() function which can be used to check if the GRUB
was locked down.
* A verifier that flags OS kernels, the GRUB modules, Device Trees and ACPI
tables as GRUB_VERIFY_FLAGS_DEFER_AUTH to defer verification to other
verifiers. These files are only successfully verified if another registered
verifier returns success. Otherwise, the whole verification process fails.
For example, PE/COFF binaries verification can be done by the shim_lock
verifier which validates the signatures using the shim_lock protocol.
However, the verification is not deferred directly to the shim_lock verifier.
The shim_lock verifier is hooked into the verification process instead.
* A set of grub_{command,extcmd}_lockdown functions that can be used by
code registering command handlers, to only register unsafe commands if
the GRUB has not been locked down.

Subject: [PATCH 19/27] script: Avoid a use-after-free when redefining a
function during execution
Defining a new function with the same name as a previously defined
function causes the grub_script and associated resources for the
previous function to be freed. If the previous function is currently
executing when a function with the same name is defined, this results
in use-after-frees when processing subsequent commands in the original
function.
Instead, reject a new function definition if it has the same name as
a previously defined function, and that function is currently being
executed. Although a behavioural change, this should be backwards
compatible with existing configurations because they can't be
dependent on the current behaviour without being broken.

Subject: [PATCH 12/46] efi: Use grub_is_lockdown() instead of hardcoding a
disabled modules list
Now the GRUB can check if it has been locked down and this can be used to
prevent executing commands that can be utilized to circumvent the UEFI
Secure Boot mechanisms. So, instead of hardcoding a list of modules that
have to be disabled, prevent the usage of commands that can be dangerous.
This not only allows the commands to be disabled on other platforms, but
also properly separate the concerns. Since the shim_lock verifier logic
should be only about preventing to run untrusted binaries and not about
defining these kind of policies.

Subject: [PATCH 15/46] commands: Restrict commands that can load BIOS or DT
blobs when locked down
There are some more commands that should be restricted when the GRUB is
locked down. Following is the list of commands and reasons to restrict:
* fakebios: creates BIOS-like structures for backward compatibility with
existing OSes. This should not be allowed when locked down.
* loadbios: reads a BIOS dump from storage and loads it. This action
should not be allowed when locked down.
* devicetree: loads a Device Tree blob and passes it to the OS. It replaces
any Device Tree provided by the firmware. This also should
not be allowed when locked down.

Subject: [PATCH 20/46] dl: Only allow unloading modules that are not
dependencies
When a module is attempted to be removed its reference counter is always
decremented. This means that repeated rmmod invocations will cause the
module to be unloaded even if another module depends on it.
This may lead to a use-after-free scenario allowing an attacker to execute
arbitrary code and by-pass the UEFI Secure Boot protection.
While being there, add the extern keyword to some function declarations in
that header file.

Subject: [PATCH 22/46] lib/arg: Block repeated short options that require an
argument
Fuzzing found the following crash:
search -hhhhhhhhhhhhhf
We didn't allocate enough option space for 13 hints because the
allocation code counts the number of discrete arguments (i.e. argc).
However, the shortopt parsing code will happily keep processing
a combination of short options without checking if those short
options require an argument. This means you can easily end writing
past the allocated option space.
This fixes a OOB write which can cause heap corruption.

Subject: [PATCH 23/46] commands/menuentry: Fix quoting in setparams_prefix()
Commit 9acdcbf32542 (use single quotes in menuentry setparams command)
says that expressing a quoted single quote will require 3 characters. It
actually requires (and always did require!) 4 characters:
str: a'b => a'\''b
len: 3 => 6 (2 for the letters + 4 for the quote)
This leads to not allocating enough memory and thus out of bounds writes
that have been observed to cause heap corruption.
Allocate 4 bytes for each single quote.
Commit 22e7dbb2bb81 (Fix quoting in legacy parser.) does the same
quoting, but it adds 3 as extra overhead on top of the single byte that
the quote already needs. So it's correct.
Fixes: CVE-2021-20233
Fixes: 9acdcbf32542 (use single quotes in menuentry setparams command)

Subject: [PATCH 24/46] kern/parser: Fix resource leak if argc == 0
After processing the command-line yet arriving at the point where we are
setting argv, we are allocating memory, even if argc == 0, which makes
no sense since we never put anything into the allocated argv.
The solution is to simply return that we've successfully processed the
arguments but that argc == 0, and also ensure that argv is NULL when
we're not allocating anything in it.
There are only 2 callers of this function, and both are handling a zero
value in argc assuming nothing is allocated in argv.

From e26b56b819c65d251d12175dd82fab4679cfbc87 Mon Sep 17 00:00:00 2001
From: Chris Coulson <chris.coulson@canonical.com>

Subject: [PATCH 30/46] kern/parser: Fix a stack buffer overflow
grub_parser_split_cmdline() expands variable names present in the supplied
command line in to their corresponding variable contents and uses a 1 kiB
stack buffer for temporary storage without sufficient bounds checking. If
the function is called with a command line that references a variable with
a sufficiently large payload, it is possible to overflow the stack
buffer via tab completion, corrupt the stack frame and potentially
control execution.
Fixes: CVE-2020-27749

Subject: [PATCH 32/46] util/mkimage: Use grub_host_to_target32() instead of
grub_cpu_to_le32()
The latter doesn't take into account the target image endianness. There is
a grub_cpu_to_le32_compile_time() but no compile time variant for function
grub_host_to_target32(). So, let's keep using the other one for this case.

set-up
There's quite a bit of code duplication in the code that sets the optional
header for PE32 and PE32+. The two are very similar with the exception of
a few fields that have type grub_uint64_t instead of grub_uint32_t.
Factor out the common code and add a PE_OHDR() macro that simplifies the
set-up and make the code more readable.

Subject: [PATCH 36/46] util/mkimage: Improve data_size value calculation
According to "Microsoft Portable Executable and Common Object File Format
Specification", the Optional Header SizeOfInitializedData field contains:
Size of the initialized data section, or the sum of all such sections if
there are multiple data sections.
Make this explicit by adding the GRUB kernel data size to the sum of all
the modules sizes. The ALIGN_UP() is not required by the PE spec but do
it to avoid alignment issues.

Subject: [PATCH 38/46] util/mkimage: Add an option to import SBAT metadata
into a .sbat section
Add a --sbat option to the grub-mkimage tool which allows us to import
an SBAT metadata formatted as a CSV file into a .sbat section of the
EFI binary.

+@section Embedded information for generation number based revocation
+
+The Secure Boot Advanced Targeting (SBAT) is a mechanism to allow the revocation
+of components in the boot path by using generation numbers embedded into the EFI
+binaries. The SBAT metadata is located in an .sbat data section that has set of
+UTF-8 strings as comma-separated values (CSV). See
+@uref{https://github.com/rhboot/shim/blob/main/SBAT.md} for more details.
+
+To add a data section containing the SBAT information into the binary, the
+@option{--sbat} option of @command{grub-mkimage} command should be used. The content
+of a CSV file, encoded with UTF-8, is copied as is to the .sbat data section into
+the generated EFI binary. The CSV file can be stored anywhere on the file system.

explicit consent
Commit 32ddc42c (efi: Only register shim_lock verifier if shim_lock
protocol is found and SB enabled) reintroduced CVE-2020-15705 which
previously only existed in the out-of-tree linuxefi patches and was
fixed as part of the BootHole patch series.
Under Secure Boot enforce loading shim_lock verifier. Allow skipping
shim_lock verifier if SecureBoot/MokSBState EFI variables indicate
skipping validations, or if GRUB image is built with --disable-shim-lock.
Fixes: 132ddc42c (efi: Only register shim_lock verifier if shim_lock
protocol is found and SB enabled)

Subject: [PATCH 45/46] squash! Add support for Linux EFI stub loading on
aarch64.
The efi shim_lock verifier has been moved to grub core so local
shim_lock protocol is no longer needed here for aarch64 efi to verify
the loaded kernel image. From now on the framework will take care the
verificaion, consolidating the integration of various security verifiers
like secure boot, gpg and tpm.

From dc56925653819582777ddc5c761a56f52dddd8f1 Mon Sep 17 00:00:00 2001
From: Alexander Graf <agraf@suse.de>
Date: Wed, 1 Feb 2017 23:10:45 +0100
Subject: [PATCH] grub-core/video/efi_gop.c: Add support for BLT_ONLY adapters
EFI GOP has support for multiple different bitness types of frame buffers
and for a special "BLT only" type which is always defined to be RGBx.
Because grub2 doesn't ever directly access the frame buffer but instead
only renders graphics via the BLT interface anyway, we can easily support
these adapters.
The reason this has come up now is the emerging support for virtio-gpu
in OVMF. That adapter does not have the notion of a memory mapped frame
buffer and thus is BLT only.

From: Andrei Borzenkov <arvidjaar@gmail.com>
Subject: [PATCH] efi/uga: use 64 bit for fb_base
We get 64 bit from PCI BAR but then truncate by assigning to 32 bit.
Make sure to check that pointer does not overflow on 32 bit platform.
Closes: 50931

ca0a4f689 verifiers: File type for fine-grained signature-verification controlling
7d36709d5 i386: make struct linux_kernel_header architecture specific
4bc909bf8 Remove grub_efi_allocate_pages.
v3:
The upstream commit
df84d6e94 efi: Print error messages to grub_efi_allocate_pages_real()
adds grub_error() to set error message and return grub_errno. We have to
unset the grub_errno if we want to ignore the error and proceed, or
the inadvertently provoked error handler would lead to unspecified
consequence.
