MinGW for i386-pc without this option generates a .rdata$zzz symbol that is
page-aligned and hence lzma_decompress no longer fits in its allocated space.
Additionally, MinGW with -fno-ident also saves a bit of space in modules. In
case of other compilers we already strip the relevant sections, so, this
option has no effect.

2) We may have a USB stick that can go into multiple boards, and the

Patch-Name: grub-install-removable-shim.patch
Some UEFI firmware is easily provoked into running out of space in its
variable storage. This is usually due to certain kernel drivers (e.g.
pstore), but regardless of the cause it can cause grub-install to fail
because it currently asks efibootmgr to delete and re-add entries, and
the deletion often doesn't result in an immediate garbage collection.
Writing variables frequently also increases wear on the NVRAM which may
have limited write cycles. For these reasons, it's desirable to find a
way to minimise writes while still allowing grub-install to ensure that
a suitable boot entry exists.
Unfortunately, efibootmgr doesn't offer an interface that would let
grub-install do this. It doesn't in general make very much effort to
minimise writes; it doesn't allow modifying an existing Boot* variable
entry, except in certain limited ways; and current versions don't have a
way to export the expected variable data so that grub-install can
compare it to the current data. While it would be possible (and perhaps
desirable?) to add at least some of this to efibootmgr, that would still
leave the problem that there isn't a good upstreamable way for
grub-install to guarantee that it has a new enough version of
efibootmgr. In any case, it's cumbersome and slow for grub-install to
have to fork efibootmgr to get things done.
Fortunately, a few years ago Peter Jones helpfully factored out a
substantial part of efibootmgr to the efivar and efiboot libraries, and
so it's now possible to have grub-install use those directly. We still
have to use some code from efibootmgr, but much less than would
previously have been necessary.
grub-install now reuses existing boot entries where possible, and avoids
writing to variables when the new contents are the same as the old
contents. In the common upgrade case where nothing needs to change, it
no longer writes to NVRAM at all. It's also now slightly faster, since
using libefivar is faster than forking efibootmgr.

This prevents grub2 from reading any further configuration residing on

grub currently copies the entire boot_params, which includes setting
sentinel byte to 0xff, which triggers sanitize_boot_params in the kernel
which in turn clears various boot_params variables, including the
indication that the bootloader chain is verified and thus the kernel
disables lockdown mode. According to the information on the Fedora bug
tracker, only the information from byte 0x1f1 is necessary, so start
copying from there instead.

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

nodes so that we use the EFI_IP4_CONFIG2_PROTOCOL and EFI_IP6_CONFIG_PROTOCOL

These two protcols are defined the sections of UEFI specification.

27.7 EFI IPv6 Configuration Protocol

Add new structure and protocol UUID of EFI_IP4_CONFIG2_PROTOCOL and

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.

Don't display introductory message about line editing unless we're

Don't clear the screen just before booting if we never drew the menu in
the first place.
Remove verbose messages printed before reading configuration. In some
ways this is awkward because it makes debugging harder, but it's a
requirement for a smooth-looking boot process; we may be able to do
better in future. Upstream doesn't want this, though.
Disable the cursor as well, for similar reasons of tidiness.
Suppress kernel/initrd progress messages, except in recovery mode.
Suppress "GRUB loading" message unless Shift is held down. Upstream
doesn't want this, as it makes debugging harder. Ubuntu wants it to
