2020-12-03cmd: add "efidebug capsule" commandAKASHI Takahiro1-0/+235
"efidebug capsule" is more or less a debugging utility. efidebug capsule update: invoke UpdateCapsule against data on memory efidebug capsule show: show a capsule header efidebug capsule result: dump a capsule result variable Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>

2020-08-13cmd/efidebug: missing initialization of load_optionsHeinrich Schuchardt1-1/+1
Variable load_options must be initialized to NULL to avoid a segmentation fault when freeing the memory this variable points to. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-08-08efi_loader: set load options in boot managerHeinrich Schuchardt1-1/+3
Up to now we used the value of the bootargs environment variable as load options in the boot manager. This is not correct. The data has to be taken from the Boot#### variable. Let the boot manager copy the optional data of the EFI_LOAD_OPTION as load options to the loaded image protocol. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-06-03efi_loader: validate load optionHeinrich Schuchardt1-6/+15
For passing the optional data of the load option to the loaded imaged protocol we need its size. efi_deserialize_load_option() is changed to return the size of the optional data. As a by-product we get a partial validation of the load option. Checking the length of the device path remains to be implemented. Some Coverity defects identified the load options as user input because get_unaligned_le32() and get_unaligned_le16() is called. But non of these Coverity defects can be resolved without marking functions with Coverity specific tags.

2020-05-19command: Remove the cmd_tbl_t typedefSimon Glass1-35/+35
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-04-16cmd: efidebug: add "test bootmgr" sub-commandAKASHI Takahiro1-1/+77
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.

2020-02-28efi_loader: Implement FileLoad2 for initramfs loadingIlias Apalodimas1-0/+4
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.

2019-05-02efi_loader: optional data in load options are binaryHeinrich Schuchardt1-10/+17
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...
