2020-03-22efi_selftest: check length reported by GetNextVariableName()Heinrich Schuchardt1-2/+8
GetNextVariableName should report the length of the variable including the final 0x0000 in bytes. Check this in the unit test. Increase the buffer size for variable names. 40 bytes is too short. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

The runtime service GetNextVariable() returns the length of the next variable including the closing 0x0000. This length should be in bytes.

2020-03-11efi_loader: get_memory_map: return parameters whenever possibleAKASHI Takahiro1-6/+6
Currently, if GetMemoryMap API returns EFI_BUFFER_TOO_SMALL, it doesn't set valid values to other parameters, descriptor_size and descriptor_version, except memory_map_size. Some efi applications, however, may use those value; in particular, xen uses descriptor_size to calculate a size of buffer to be allocated. While UEFI specification is ambiguous in this point, it would be better to address this issue proactively to maximize the compatibility with existing efi applications. With this patch, for example, xen.efi (and hence linux kernel) can be started via bootefi without modification.

Provide a unit test loading an initial ramdisk using the EFI_LOAD_FILE2_PROTOCOL. The test is only executed on request. An example usage - given a file image with a file system in partition 1 holding file initrd - is: * Configure the sandbox with CONFIG_EFI_SELFTEST=y CONFIG_EFI_LOAD_FILE2_INITRD=y CONFIG_EFI_INITRD_FILESPEC="host 0:1 initrd" * Run ./u-boot and execute host bind 0 image setenv efi_selftest load initrd bootefi selftest This would provide a test output like: Testing EFI API implementation Selected test: 'load initrd' Setting up 'load initrd' Setting up 'load initrd' succeeded Executing 'load initrd' Loaded 12378613 bytes CRC32 2997478465 Executing 'load initrd' succeeded Now the size and CRC32 can be compared to the provided file.

2020-02-28efi_loader: Implement FileLoad2 for initramfs loadingIlias Apalodimas4-0/+219
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.

2020-02-06dm: core: Create a new header file for 'compat' featuresSimon Glass24-0/+24
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-02-06dm: core: Require users of devres to include the headerSimon Glass7-0/+10
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

2020-01-30libfdt: Revert 6dcb8ba4 from upstream libfdtTom Rini1-10/+10
In upstream libfdt, 6dcb8ba4 "libfdt: Add helpers for accessing unaligned words" introduced changes to support unaligned reads for ARM platforms and 11738cf01f15 "libfdt: Don't use memcpy to handle unaligned reads on ARM" improved the performance of these helpers. In practice however, this only occurs when the user has forced the device tree to be placed in memory in a non-aligned way, which in turn violates both our rules and the Linux Kernel rules for how things must reside in memory to function. This "in practice" part is important as handling these other cases adds visible (1 second or more) delay to boot in what would be considered the fast path of the code.
