495781f5ed btrfs: Add support for new RAID1C34 profiles
New 3- and 4-copy variants of RAID1 were merged into Linux kernel 5.5.
Add the two new profiles to the list of recognized ones. As this builds
on the same code as RAID1, only the redundancy level needs to be
adjusted, the rest is done by the existing code.

5e5a15872d grub-editenv: Warn a user against editing environment block
The environment block is a preallocated 1024-byte file which serves as
persistent storage for environment variables. It has its own format
which is sensitive to corruption if an editor does not know how to
process it. Besides that the editor may inadvertently change grubenv
file size and/or make it sparse which can lead to unexpected results.

This patch adds a message to the grubenv file to warn a user against
editing it by tools other than grub-editenv.

42acdd3b40 hostdisk: Set linux file descriptor to O_CLOEXEC as default
We are often bothered by this sort of lvm warning while running grub-install
every now and then:

  File descriptor 4 (/dev/vda1) leaked on vgs invocation. Parent PID 1991: /usr/sbin/grub2-install

The requirement related to the warning is dictated in the lvm man page:

  "On invocation, lvm requires that only the standard file descriptors stdin,
  stdout and stderr are available.  If others are found, they get closed and
  messages are issued warning about the leak.  This warning can be suppressed by
  setting the environment variable LVM_SUPPRESS_FD_WARNINGS."

While it could be disabled through settings, most Linux distributions seem to
enable it by default and the justification provided by the developer looks to
be valid to me: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466138#15

Rather than trying to close and reopen the file descriptor to the same file
multiple times, which is rather cumbersome, for the sake of no vgs invocation
could happen in between. This patch enables the close-on-exec flag (O_CLOEXEC)
for new file descriptor returned by the open() system call, making it closed
thus not inherited by the child process forked and executed by the exec()
family of functions.

Fixes Debian bug #466138.

28a7e597de grub-mkconfig: Use portable "command -v" to detect installed programs
The "which" utility is not guaranteed to be installed either, and if it
is, its behavior is not portable either.

Conversely, the "command -v" shell builtin is required to exist in all
POSIX 2008 compliant shells, and is thus guaranteed to work everywhere.

Examples of open-source shells likely to be installed as /bin/sh on
Linux, which implement the 11-year-old standard: ash, bash, busybox,
dash, ksh, mksh and zsh.

A side benefit of using the POSIX portable option is that it requires
neither an external disk executable, nor (because unlike "which", the
exit code is reliable) a subshell fork. This therefore represents a mild
speedup.

b78d570a36 templates: Add GRUB_DISABLE_UUID
The grub-mkconfig and 10_linux scripts by default attempt to use a UUID to
set the root kernel command line parameter and the $root GRUB environment
variable.

The former can be disabled by setting the GRUB_DISABLE_LINUX_UUID variable
to "true", but there is currently no way to disable the latter.

The generated grub config uses the search command with the --fs-uuid option
to find the device that has to be set as $root, i.e:

 search --no-floppy --fs-uuid --set=root ...

This is usually more reliable but in some cases it may not be appropriate,
so this patch introduces a new GRUB_DISABLE_UUID variable that can be used
to disable searching for the $root device by filesystem UUID.

When disabled, the $root device will be set to the value specified in the
device.map as found by the grub-probe --target=compatibility_hint option.

When setting GRUB_DISABLE_UUID=true, the GRUB_DISABLE_LINUX_UUID and
GRUB_DISABLE_LINUX_PARTUUID variables will also be set to "true" unless
these have been explicitly set to "false".

That way, the GRUB_DISABLE_UUID variable can be used to force using the
device names for both GRUB and Linux.

33203ca348 at_keyboard: Fix unreliable key presses
This patch fixes an issue that prevented the at_keyboard module to work
(for me). The cause was a bad/wrong return value in the
grub_at_keyboard_getkey() function in grub-core/term/at_keyboard.c file
at line 237. My symptoms were to have an unresponsive keyboard. Keys
needed to be pressed 10x and more to effectively be printed sometimes
generating multiple key presses (after 1 or 2 sec of no printing). It
was very problematic when typing passphrase in early stage (with
GRUB_ENABLE_CRYPTODISK). When switched to "console" terminal input
keyboard worked perfectly. It also worked great with the GRUB 2.02
packaged by Debian (2.02+dfsg1-20). It was not an output issue but an
input one.

I've managed to analyze the issue and found that it came from the commit
216950a4e (at_keyboard: Split protocol from controller code.). Three
lines where moved from the fetch_key() function in
grub-core/term/at_keyboard.c file to the beginning of
grub_at_keyboard_getkey() function (same file). However, returning -1
made sense when it happened in fetch_key() function but not anymore in
grub_at_keyboard_getkey() function which should return GRUB_TERM_NO_KEY.
I think it was just an incomplete cut-paste missing a small manual
correction. Let's fix it.

ee4bd79ef2 templates: Fix bad test on GRUB_DISABLE_SUBMENU
The GRUB_DISABLE_SUBMENU option is different than the others in the sense
that it has to be set to "y" instead of "true" to be enabled.

That causes a lot of confusion to users, some may wrongly set it to "true"
expecting that will work the same than with most options, and some may set
it to "yes" since for other options the value to set is a word and not a
single character.

This patch changes all the grub.d scripts using the GRUB_DISABLE_SUBMENU
option, so they check if it was set to "true" instead of "y", making it
consistent with all the other options.

But to keep backward compatibility for users that set the option to "y" in
/etc/default/grub file, keep testing for this value. And also do it for
"yes", since it is a common mistake made by users caused by this option
being inconsistent with the others.

we still still have the 'auto' default to fall back to. Allow getting to this
fallback by not trying to parse 'text' as a modespec.

This is because 'text' correctly doesn't parse as a modespec, and ought to have
been ignored before we got to that point, just like it is immediately picked if
we're running on a system where 'text' is a supported video mode.

2 * indirect_blks + dindirect_blks. The uninitialized offset is then used
by function grub_f2fs_get_block() because level == 0 is valid and
meaningful return to be processed.

The fix is to set level = -1 as return value by grub_get_node_path() to
signify an error that the input block cannot be handled. Any caller
should therefore check level is negative or not before processing the
output.

When creating T32->A32 transition jumps, the relocation code in grub

because everything became page aligned.

4dd4ceec02 efi: Fix gcc9 error -Waddress-of-packed-member
The address of fp->path_name could be unaligned since seeking into the
device path buffer for a given node could end in byte boundary.

The fix is allocating aligned buffer by grub_malloc for holding the
UTF16 string copied from fp->path_name, and after using that buffer as
argument for grub_utf16_to_utf8 to convert it to UTF8 string.

621024090b hfsplus: Fix gcc9 error with -Waddress-of-packed-member
The catkey->name could be unaligned since the address of 'void* record'
is calculated as offset in bytes to a malloc buffer.

The fix is using aligned buffer allocated by grub_malloc for holding
the UTF16 string copied from catkey->name. And use that buffer as
argument for grub_utf16_to_utf8 to convert to UTF8 strings.

In addition, using a new copy of buffer rather than catkey->name itself
for processing the endianess conversion, we can also get rid of the hunk
restoring byte order of catkey->name to what it was previously.

bc58fded50 efi: Avoid NULL dereference if FilePath is NULL
The UEFI specification allows LoadImage() to be called with a memory
location only and without a device path. In this case FilePath will not be
set in the EFI_LOADED_IMAGE_PROTOCOL.

So in function grub_efi_get_filename() the device path argument may be
NULL. As we cannot determine the device path in this case just return NULL
from the function.

acc726f812 x86/msr: Fix build with older GCC versions
Some older GCC versions produce following error when x86 MSR modules are build:

  In file included from commands/i386/rdmsr.c:29:0:
  ../include/grub/i386/rdmsr.h:27:29: error: no previous prototype for ‘grub_msr_read’ [-Werror=missing-prototypes]

                               ^
  cc1: all warnings being treated as errors

This happens due to lack of support for a such usage of extern keyword
in older GCCs. Additionally, this usage is not consistent with the rest
of codebase. So, replace it with static keyword.

Additionally, fix incorrect coding style.
