2019-10-17efi_loader: disk: install FILE_SYSTEM_PROTOCOL only if availableAKASHI Takahiro1-1/+23
In the current implementation, EFI_SIMPLEFILE_SYSTEM_PROTOCOL is always installed to all the partitions even if some of them may house no file system. With this patch, that protocol will be installed only if any file system exists. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-10-17efi_loader: device_path: check against file path lengthAKASHI Takahiro1-2/+9

2019-10-15rsa: Return immediately if required-key verification failsDaniele Alessandrelli1-2/+1
Currently, if image verification with a required key fails, rsa_verify() code tries to find another key to verify the FIT image. This however, is not the intended behavior as the documentation says that required keys "must be verified for the image / configuration to be considered valid". This patch fixes the issue by making rsa_verify() return immediately if the verification of a required key fails. Signed-off-by: Daniele Alessandrelli <daniele.alessandrelli@gmail.com>

2019-10-08spl: Allow tiny printf() to be controlled in SPL and TPLSimon Glass2-5/+17
At present there is only one control for this and it is used for both SPL and TPL. But SPL might have a lot more space than TPL so the extra cost of a full printf() might be acceptable. Split the option into two, providing separate SPL and TPL controls. The TPL setting defaults to the same as SPL.

2019-10-06efi_selftest: testing read-only variablesHeinrich Schuchardt1-11/+0
The UEFI spec has this sentence: "Variables that have runtime access but that are not nonvolatile are read-only data variables once ExitBootServices() is performed." At least EDK2 therefore treats variable PlatformLangCodes only as read-only at runtime. Nowhere do we make this variable read-only in U-Boot. Do not use variable PlatformLangCodes for testing if the read only attribute of variables is observed before ExitBootServices().

2019-09-20efi_loader: device_path: support Sandbox's "host" devicesAKASHI Takahiro1-0/+33
Sandbox's "host" devices are currently described as UCLASS_ROOT udevice with DEV_IF_HOST block device. As the current implementation of efi_device_path doesn't support such a type, any "host" device on sandbox cannot be seen as a distinct object. For example, => host bind 0 /foo/disk.img => efi devices Scanning disk host0... Found 1 disks Device Device Path ================ ==================== 0000000015c19970 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b) 0000000015c19d70 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b) => efi dh Handle Protocols ================ ==================== 0000000015c19970 Device Path, Device Path To Text, Device Path Utilities, Unicode Collation 2, HII String, HII Database, HII Config Routing 0000000015c19ba0 Driver Binding 0000000015c19c10 Simple Text Output 0000000015c19c80 Simple Text Input, Simple Text Input Ex 0000000015c19d70 Block IO, Device Path, Simple File System As you can see here, efi_root (0x0000000015c19970) and host0 device (0x0000000015c19d70) have the same representation of device path. This is not only inconvenient, but also confusing since two different efi objects are associated with the same device path and efi_dp_find_obj() will possibly return a wrong result. Solution: Each "host" device should be given an additional device path node of "vendor device path" to make it distinguishable.

2019-09-09efi_loader: correct reading of directoriesHeinrich Schuchardt1-18/+5
EFI_FILE_PROTOCOL.Read() is used both to read files and directories. When reaching the end of a directory we always have to return buffer size zero irrespective of the incoming buffer size. (The described scenario for a Shim quirk cannot arise because every directory has at least '.' and '..' as entries.) Even when the buffer_size is too small multiple times we have to keep a reference to our last read directory entry. When we return to the start of the directory via SetPosition() we must remove the reference to a previously kept directory entry. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
