efi_loader: fix entry count in bootmgr

2019-02-25T11:39:48Z

Since commit 914df75b0c97 ("efi_loader: fix EFI entry counting") entry_count is already set to 1 before efi_bootmgr_load() is called. So we should not increment it when entering the function. Without the patch an assert error occurs in efi_get_variable() if DEBUG is defined. Fixes: 914df75b0c97 ("efi_loader: fix EFI entry counting") Signed-off-by: Heinrich Schuchardt

efi_loader: error message if BootOrder not defined

2019-02-25T11:39:47Z

For booting via `bootefi bootmgr` it is necessary that the EFI variable BootOrder is defined. Provide a diagnostic message if the variable is missing. Signed-off-by: Heinrich Schuchardt

efi_loader: do not miss last relocation block

2019-02-16T14:51:14Z

If the last block in the relocation table contains only a single relocation, the current coding ignores it. Fix the determination of the end of the relocation table. Signed-off-by: Heinrich Schuchardt

efi_loader: fix EFI entry counting

2019-02-16T14:42:20Z

`bootefi selftest` fails on qemu-x86_defconfig if efi_selftest() is not invoked using EFI_CALL(). Likewise we call the entry point of EFI payloads with EFI_CALL(efi_start_image()). entry_count indicates if we are in U-Boot (1) or in EFI payload code (0). As we start in U-Boot code the initial value has to be 1. Signed-off-by: Heinrich Schuchardt

efi_loader: use efi_start_image() for bootefi

2019-02-16T14:42:20Z

Remove the duplicate code in efi_do_enter() and use efi_start_image() to start the image invoked by the bootefi command. Signed-off-by: Heinrich Schuchardt

efi_loader: set entry point in efi_load_pe()

2019-02-16T14:42:20Z

Up to now efi_load_pe() returns the entry point or NULL in case of an error. This does not allow to return correct error codes from LoadImage(). Let efi_load_pe() return a status code and fill in the entry point in the corresponding field of the image object. Signed-off-by: Heinrich Schuchardt

efi_loader: LoadImage: always allocate new pages

2019-02-16T14:42:20Z

If we want to properly unload images in Exit() the memory should always be allocated in the same way. As we allocate memory when reading from file we should do the same when the original image is in memory. A further patch will be needed to free the memory when Exit() is called.

efi_loader: error handling in efi_setup_loaded_image()

2019-02-16T14:42:20Z

In case of an error we should set the returned pointers to NULL. This ensures that an illegal free does not occur even if the caller calls free() for the handles. If protocols cannot be installed, release all resources. Signed-off-by: Heinrich Schuchardt
