The current code is incorrectly failing to load the fbaa64.efi image found
in Arm servers even though the UEFI shell code is able to properly load
and execute the same image.
The problem is due to the presence of a section header that has zero size
and address and marked "discardable" in the fbaa64.efi image.
Although there is already a check further down in the code to look for
the discardable bit and skip further verification checks if set, we never
get to that point due to the "end < base" check at the start of the loop.
Here is a dump of the fbaa64.efi image as compiled on an Arm machine
from the latest code in this repo:
% # First I used hexedit to change header byte from 'AA' to '86'
% # so that objdump was able to correctly parse the file:
% objdump -x -m aarch64 fbaa64.efi

When shim is invoked from a relative path (e.g: from the UEFI shell), the
Loaded Image handle LoadOptions can be set to the binary relative path.
But the is_our_path() function only checks if LoadOptions is set to the
absolute path of shim to ignore it. So if a relative path is there, shim
would set itself as the secondary loader and invoke itself in a loop.
To prevent that, use the path in LoadOptions to calculate the absolute
path and compare it with the one in the Loader Image handle FilePath.

The generate_path_from_image_path() doesn't properly handle the case when
shim is invoked using a relative path (e.g: from the EFI shell). In that
function, always the last component is stripped from absolute file path
to calculate the dirname, and this is concatenated with the image path.
But if the path is a relative one, the function will wrongly concatenate
the dirname with the relative image path, i.e:
Shell> FS0:
FS0:\> cd EFI
FS0:\EFI\> BOOT\BOOTX64.EFI
Failed to open \EFI\BOOT\BOOT\BOOTX64.EFI - Not found
Failed to load image \EFI\BOOT\BOOT\BOOTX64.EFI: Not found
start_image() returned Not found
Calculate the image path basename and concatenate that with the dirname.

When writing MokList with EFI_VARIABLE_APPEND_WRITE, some HP laptops
may just return EFI_SUCCESS without writing the content into the flash,
so we have no way to detect if MokList is updated or not. Now we always
read MokList first and write it back with the new content.

This timeout can have the values [-1,0..0x7fff]; where -1 means "no timeout",
with MokManager going directly to the menu, and is capped to 0x7fff to avoid
unecessary long timeouts. The default remains 10, which will be used whenever
the MokTimeout variable isn't set.

This was merged before it was really ready - verify_trusted_cert needs
to check each certificate against vendor_dbx, "dbx", and "MokListX", or
else it can enable a blacklisted certificate accidentally.

Everything Hans said was correct. But StrnCat() is in gnu-efi 3.0.8,
and using just StrCpy() here confuses coverity. I'd rather have a CI
page that's not completely full of chaff, but a little bit of redundancy
in the code.

StrnCat is not available in gnu-efi-3.0.5 (I did not check if it does
actually exists in 3.0.6). Moreover using strcat on a buffer where we've
just done: "buf[0] = '\0'" is a bit silly, we might as well drop the 0
termination and just use strcpy.
It seems there also is no StrnCpy in gnu-efi-3.0.5, but we are passing in
a pointer to the end of file_name minus 4, so strcpy will consume only
4 bytes anyways and there is no need for the "n".

Remove the setup_console(1) calls from shim and instead make lib/console.c
make that call when necessary. This avoids shim forcing the EFI console to
switch to text-mode if nothing is printed.
This commit also modifies MokManager to work the same way for consistency,
even though MokManager will always print something.

This is a preparation commit for removing the setup_console(1) calls from
MokManager and shim so that we don't force the EFI console to switch to
text-mode.
This commit replaces all direct calls to Print / PrintAt with calls to
the new helpers (no functional changes) so that we can delay calling
setup_console(1) till the first Print call in a follow-up patch.

When the firmware is using EFI_LOAD_OPTION to specify options for the secondary
loader, the shim will properly detect that and return in set_second_stage. Later
howerer in handle_image EFI_LOADED_IMAGE is being overwritten with load_option
irrespective of the fact that load_option was never set. This effectively
prevents the EFI_LOAD_OPTION from reaching the secondary loader.
Only overwrite EFI_LOADED_IMAGE's LoadOptions when load_option is not NULL
solves the problem.
