2020-04-16cmd: efidebug: add "test bootmgr" sub-commandAKASHI Takahiro
This sub-command will be used to test image authentication, in particular, a case where efi_load_image() failed with EFI_SECURITY_VIOLATION but we still want to try efi_start_image(). We won't run such a case under normal bootmgr because it simply refuses to call efi_start_image() if anything but EFI_SUCCESS is returned when loading an image.

2020-03-17cmd: map addresses to sysmem in efidebug memmapHeinrich Schuchardt
Addresses in the sandbox's device tree are in the sandbox's virtual address space. If we want to compare memory reservations in the device-tree with the output of 'efidebug memmap', we need to convert back to this address space. Adjust the output of the 'efidebug memmap' command.

2020-03-11cmd: efidebug: fix a failure of "boot rm" sub-commandAKASHI Takahiro
There is a wrong usage of utf8_utf16_strncpy() in "boot rm" command, and then it will end up with a failure of this command due to a wrong value of an interim variable ("var_name16"). Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-02-28efi_loader: Implement FileLoad2 for initramfs loadingIlias Apalodimas
Following kernel's proposal for an arch-agnostic initrd loading mechanism [1] let's implement the U-boot counterpart. This new approach has a number of advantages compared to what we did up to now. The file is loaded into memory only when requested limiting the area of TOCTOU attacks. Users will be allowed to place the initramfs file on any u-boot accessible partition instead of just the ESP one. Finally this is an attempt of a generic interface across architectures in the linux kernel so it makes sense to support that. The file location is intentionally only supported as a config option argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security. Although U-boot is not responsible for verifying the integrity of the initramfs, we can enhance the offered security by only accepting a built-in option, which will be naturally verified by UEFI Secure Boot. This can easily change in the future if needed and configure that via ENV or UEFI variable.

2020-01-07cmd: efidebug: simplify get_guid_text()Heinrich Schuchardt
When we hit a matching GUID we can directly return the text. There is no need for a check after the loop. efi_guid_t is defined as 8 byte aligned but GUIDs in packed structures do not follow this alignment. Do not require the argument of get_guid_text() to be correctly aligned. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-05-02efi_loader: optional data in load options are binaryHeinrich Schuchardt
The field boot OptionalData in structure _EFI_LOAD_OPTIONS is for binary data. When we use `efidebug boot add` we should convert the 5th argument from UTF-8 to UTF-16 before putting it into the BootXXXX variable. When printing boot variables with `efidebug boot dump` we should support the OptionalData being arbitrary binary data. So let's dump the data as hexadecimal values. Here is an example session protocol: => efidebug boot add 00a1 label1 scsi 0:1 doit1 'my option' => efidebug boot add 00a2 label2 scsi 0:1 doit2 => efidebug boot dump Boot00A0: attributes: A-- (0x00000001) label: label1 file_path: .../HD(1,MBR,0xeac4e18b,0x800,0x3fffe)/doit1 data: 00000000: 6d 00 79 00 20 00 6f 00 70 00 74 00 69 00 6f 00 m.y. .o.p.t.i.o. 00000010: 6e 00 00 00 n...

2019-04-23efi_loader: consistent naming of protocol GUIDsHeinrich Schuchardt
We should consistently use the same name for protocol GUIDs as defined in the UEFI specification. Not adhering to this rule has led to duplicate definitions for the EFI_LOADED_IMAGE_PROTOCOL_GUID.

Currently, there is no easy way to add or modify UEFI variables. In particular, bootmgr supports BootOrder/BootXXXX variables, it is quite hard to define them as u-boot variables because they are represented in a complicated and encoded format. The new command, efidebug, helps address these issues and give us more friendly interfaces: * efidebug boot add: add BootXXXX variable * efidebug boot rm: remove BootXXXX variable * efidebug boot dump: display all BootXXXX variables * efidebug boot next: set BootNext variable * efidebug boot order: set/display a boot order (BootOrder) Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
