2025-03-15test/py: Shorten u_boot_consoleSimon Glass
This fixture name is quite long and results in lots of verbose code. We know this is U-Boot so the 'u_boot_' part is not necessary. But it is also a bit of a misnomer, since it provides access to all the information available to tests. It is not just the console. It would be too confusing to use con as it would be confused with config and it is probably too short. So shorten it to 'ubman'.

2024-06-10efi_loader: Fix EFI_VARIABLE_APPEND_WRITE hash checkWeizhao Ouyang
According to UEFI v2.10 spec section 8.2.6, if a caller invokes the SetVariables() service, it will produce a digest from hash(VariableName, VendorGuid, Attributes, TimeStamp, DataNew_variable_content), then the firmware that implements the SetVariable() service will compare the digest with the result of applying the signer’s public key to the signature. For EFI variable append write, efitools sign-efi-sig-list has an option "-a" to add EFI_VARIABLE_APPEND_WRITE attr, and u-boot will drop this attribute in efi_set_variable_int(). So if a caller uses "sign-efi-sig-list -a" to create the authenticated variable, this append write will fail in the u-boot due to "hash check failed". This patch resumes writing the EFI_VARIABLE_APPEND_WRITE attr to ensure that the hash check is correct. And also update the "test_efi_secboot" test case to compliance with the change.

2024-05-01efi_loader: improve error handling in try_load_entry()Heinrich Schuchardt
The image is not unloaded if a security violation occurs. If efi_set_load_options() fails, we do not free the memory allocated for the optional data. We do not unload the image. * Unload the image if a security violation occurs. * Free load_options if efi_set_load_options() fails. * Unload the image if efi_set_load_options() fails.

2023-11-18efi_loader: Boot var automatic managementRaymond Mao
Changes for complying to EFI spec §3.5.1.1 'Removable Media Boot Behavior'. Boot variables can be automatically generated during a removable media is probed. At the same time, unused boot variables will be detected and removed. Please note that currently the function 'efi_disk_remove' has no ability to distinguish below two scenarios a) Unplugging of a removable media under U-Boot b) U-Boot exiting and booting an OS Thus currently the boot variables management is not added into 'efi_disk_remove' to avoid boot options being added/erased repeatedly under scenario b) during power cycles See TODO comments under function 'efi_disk_remove' for more details The original efi_secboot tests expect that BootOrder EFI variable is not defined. With this commit, the BootOrder EFI variable is automatically added when the disk is detected. The original efi_secboot tests end up with unexpected failure. The efi_secboot tests need to be modified to explicitly set the BootOrder EFI variable. squashfs and erofs ls tests are also affected by this modification, need to clear the previous state before squashfs ls test starts.

2021-04-24test/py: Fix efidebug related testsIlias Apalodimas
commit cbea241e935e("efidebug: add multiple device path instances on Boot####") slightly tweaked the efidebug syntax adding -b, -i and -s for the boot image, initrd and optional data. The pytests using this command were adapted as well. However I completely missed the last "" argument, which at the time indicated the optional data and needed conversion as well. This patch is adding the missing -s flag and the tests are back to normal.

2021-03-25efidebug: add multiple device path instances on Boot####Ilias Apalodimas
The UEFI spec allows a packed array of UEFI device paths in the FilePathList[] of an EFI_LOAD_OPTION. The first file path must describe the loaded image but the rest are OS specific. Previous patches parse the device path and try to use the second member of the array as an initrd. So let's modify efidebug slightly and install the second file described in the command line as the initrd device path. Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>

2020-05-04test: stabilize test_efi_secbootHeinrich Schuchardt
When setting up the console via function efi_console_register() we call query_console_serial(). This functions sends an escape sequence to the terminal to query the display size. The response is another escape sequence. console.run_command_list() is looking for a regular expression '^==>'. If the escape sequence for the screen size precedes the prompt without a line break, no match is found. When efi_disk_register() is called before efi_console_register() this leads to a test failuere of the UEFI secure boot tests. We can avoid the problem if the first UEFI command passed to u_boot_console.run_command_list() produces output. This patch achieves this by appending '; echo' to the first UEFI related command of the problematic tests. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
