2021-03-25efi_loader: Replace config option for initrd loadingIlias Apalodimas
Up to now we install EFI_LOAD_FILE2_PROTOCOL to load an initrd unconditionally. Although we correctly return various EFI exit codes depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the kernel loader, only falls back to the cmdline interpreted initrd if the protocol is not installed. This creates a problem for EFI installers, since they won't be able to load their own initrd and continue the installation. It also makes the feature hard to use, since we can either have a single initrd or we have to recompile u-boot if the filename changes. So let's introduce a different logic that will decouple the initrd path from the config option we currently have. When defining a UEFI BootXXXX we can use the filepathlist and store a file path pointing to our initrd. Specifically the EFI spec describes: "The first element of the array is a device path that describes the device and location of the Image for this load option. Other device paths may optionally exist in the FilePathList, but their usage is OSV specific" When the EFI application is launched through the bootmgr, we'll try to interpret the extra device path. If that points to a file that exists on our disk, we'll now install the load_file2 and the efi-stub will be able to use it. This opens up another path using U-Boot and defines a new boot flow. A user will be able to control the kernel/initrd pairs without explicit cmdline args or GRUB.

2021-03-25efi_loader: Add helper functions for EFIIlias Apalodimas
A following patch introduces a different logic for loading initrd's based on the EFI_LOAD_FILE2_PROTOCOL. Since similar logic can be applied in the future for other system files (i.e DTBs), let's add some helper functions which will retrieve and parse file paths stored in EFI variables.

2021-03-25efi_loader: Add device path related functions for initrd via Boot####Ilias Apalodimas
On the following patches we allow for an initrd path to be stored in Boot#### variables. Specifically we encode in the FIlePathList[] of the EFI_LOAD_OPTIONS for each Boot#### variable. The FilePathList[] array looks like this: kernel - 0xff - VenMedia(initrd GUID) - initrd1 - 0x01 initrd2 - 0xff So let's add the relevant functions to concatenate and retrieve a device path based on a Vendor GUID.

2021-02-14efi_loader: fix get_last_capsule()Heinrich Schuchardt
fix get_last_capsule() leads to writes beyond the stack allocated buffer. This was indicated when enabling the stack protector. utf16_utf8_strcpy() only stops copying when reaching '\0'. The current invocation always writes beyond the end of value[]. The output length of utf16_utf8_strcpy() may be longer than the number of UTF-16 tokens. E.g has "CapsuleКиев" has 11 UTF-16 tokens but 15 UTF-8 tokens. Hence, using utf16_utf8_strcpy() without checking the input may lead to further writes beyond value[]. The current invocation of strict_strtoul() reads beyond the end of value[]. A non-hexadecimal value after "Capsule" (e.g. "CapsuleZZZZ") must result in an error. We cat catch this by checking the return value of strict_strtoul(). A value that is too short after "Capsule" (e.g. "Capsule0") must result in an error. We must check the string length of value[].

Also in some cases the version needs to be generated programmatically, such as when it is stored elsewhere in the ROM and must be read first.
