Subject: [PATCH 1/3] Make sure that MOK variables always get mirrored
|
||||
|
||||
Without this, if a Mok variable doesn't exist in Boot Services, it will also
|
||||
not be copied to Runtime, even if we have data to be added to it (vendor cert).
|
||||
This patch makes sure that if we have extra data to append, we still mirror
|
||||
the variable.

Subject: [PATCH 2/3] mok: fix the mirroring of RT variables
|
||||
|
||||
When there is no key in MokList, import_mok_state() just skipped MokList
|
||||
even though it should always mirror the vendor cert. Besides, the faulty
|
||||
check of 'present' and 'addend' invalidates the mirroring of MokListXRT,
|
||||
MokSBStateRT, and MokIgnoreDB.

Subject: [PATCH] Make EFI variable copying fatal only on secureboot enabled
|
||||
systems
|
||||
|
||||
I have come across systems that are unwilling to reserve enough memory for
|
||||
a MokListRT big enough for big certificates.
|
||||
This seems to be the case with firmware implementations that do not support
|
||||
secureboot, which is probably the reason they went with much lower variable
|
||||
storage.
|
||||
|
||||
This patch set makes sure we can still boot on those systems, by only
|
||||
making the copy action fatal if the system has secure boot enabled, or if
|
||||
the error was anything other than EFI_INVALID_PARAMETER.

Subject: [PATCH] shim: Properly generate absolute paths from relative
|
||||
image paths
|
||||
|
||||
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.

Subject: [PATCH] shim: Prevent shim to set itself as a second stage loader
|
||||
|
||||
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.

Subject: [PATCH] translate_slashes(): don't write to string literals
|
||||
|
||||
Currently, all three invocations of the translate_slashes() function may
|
||||
lead to writes to the string literal that is #defined with the
|
||||
DEFAULT_LOADER_CHAR macro. According to ISO C99 6.4.5p6, this is undefined
|
||||
behavior ("If the program attempts to modify such an array, the behavior
|
||||
is undefined").
|
||||
|
||||
This bug crashes shim on e.g. the 64-bit ArmVirtQemu platform ("Data
|
||||
abort: Permission fault"), where the platform firmware maps the .text
|
||||
section (which contains the string literal) read-only.
|
||||
|
||||
Modify translate_slashes() so that it copies and translates characters
|
||||
from an input array of "char" to an output array of "CHAR8".
|
||||
|
||||
While at it, fix another bug. Before this patch, if translate_slashes()
|
||||
ever encountered a double backslash (translating it to a single forward
|
||||
slash), then the output would end up shorter than the input. However, the
|
||||
output was not NUL-terminated in-place, therefore the original string
|
||||
length (and according trailing garbage) would be preserved. After this
|
||||
patch, the NUL-termination on contraction is automatic, as the output
|
||||
array's contents are indeterminate when entering the function, and so we
|
||||
must NUL-terminate it anyway.
