__WORDSIZE does not seem to be documented anywhere, and is probably
meant to be used internally by glibc headers.
In systemd, it was only being used in warning messages. We can avoid
using it by rewording the messages slightly.
Fixes a build error with musl libc.
Bug: https://bugs.gentoo.org/894430
This is just a workaround. Once we drop gnu-efi, the arm build system
for EFI binaries should be changed to use the arm-none-eabi toolchain,
which should not exhibit this behavior.
This will be used by Tpm2Handle instances, which is added in later patches.
The refcounting allows the context to be retained until all Tpm2Handles have
been cleaned up, and the initial ref is released, before cleaning the context.
The 'pcr_bank' functions operate on hash algs, and are not specific to the PCR
banks, while the 'primary_alg' functions operate on asymmetric algs, and are
not specific to primary keys.
Follow-ups for 8702496bfb.
- add missing error cause in logging,
- add several missing assertions,
- drop an unnecessary initialization,
- make boot_config_find_in() return negative errno if nothing found,
- and several coding style fixlets.
Follow-ups for #26124 and #26158.
- use os_release_pretty_name(),
- constify the buffer passed to inspect_osrel(),
- propagate errors in inspect_osrele(), and ignore them in the caller
side,
- and several coding style fixlets.
When compiled without ENABLE_EFI, efi_stub_measured() was not defined, so
compilation would fail. But it's not enough to add a stub that returns
-EOPNOTSUPP. We call this function in various places and usually print the error
at warning or error level, so we'd print a confusing message. We also can't add
a stub that always returns 0, because then we'd print a message like "Kernel
stub did not measure", which would be confusing too. Adding special handling for
-EOPNOTSUPP in every caller is also unattractive. So instead efi_stub_measured()
is reworked to log the warning or error internally, and such logging is removed
from the callers, and a stub is added that logs a custom message.
Binutils 2.38 added support for efi-app-aarch64
Still use binary mode if we have an older objcopy
Add check for incompatible gnu-efi crt0 containing the header section
which gets added by objcopy and if used results in duplicate header
and subsequently a broken binary

libefi.a just provided the c helper API that was slowly removed. As we
do not depend on anything provided by it anymore, it is safe to drop
now.
Since the ST/BS/RT pointers are very convenient and needed everywhere,
they are retained and initialized by us.
This stops using global GUID variables provided by gnu-efi. The globals
presumably exist to make EFI calls easier. But these GUIDs are just
128bits, so it's cheap to just put them on the stack when needed. C99
compound literals makes this even easier.
This also adds a convenience macro to create GUID pointers and uses it
everywhere. Not forcing a GUID definition to be a compound literal makes
them easier to use when assigning them to variables:
EFI_GUID before = *SOME_CONST_GUID;
EFI_GUID after = SOME_GUID;
And MAKE_GUID_PTR() makes it more explicit what is happening. It was
easy to confuse the old code as a cast:
before(&(EFI_GUID) SOME_GUID);
after(MAKE_GUID_PTR(SOME));
grub (at least on fedora) nowadays implements the boot loader spec, but
not the boot loader interface. Hence let's split out the commands
specific to each in two groups in the --help text. This way the first
group just covers boot lodaer spec stuff (i.e. stuff on disk in the
ESP/XBOOTLDR partition). And the other covers talking to the boot loader
via EFI var.
Removing debugging related sections is apparently not enough to truely
strip a (PE) binary.
Better late than never. It gets rid of this pesky warning from sbsign:
warning: data remaining[174080 vs 193173]: gaps between PE/COFF sections?
The unlink command removes an entry from the ESP including
referenced files that are not referenced in other entries. That is
useful eg to have multiple entries that use the same kernel with
different options.
The cleanup command removes all files that are not referenced by any
entry.
The custom print helpers have been replaced with explicit checks at the
call site to keep this in line with the way it is done in userspace. Any
calls where the check has been ommited should not need them as the value
is expected to alawys be around.
