2019-02-16efi_loader: fix EFI entry countingHeinrich Schuchardt
`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 <xypron.glpk@gmx.de>
2019-02-16efi_loader: use efi_start_image() for bootefiHeinrich Schuchardt
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 <xypron.glpk@gmx.de>
2019-02-16efi_loader: set entry point in efi_load_pe()Heinrich Schuchardt
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 <xypron.glpk@gmx.de>
2019-02-16efi_loader: LoadImage: always allocate new pagesHeinrich Schuchardt
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. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-02-16efi_loader: error handling in efi_setup_loaded_image()Heinrich Schuchardt
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 <xypron.glpk@gmx.de>
2019-02-16lib/vsprintf: print '?' for illegal Unicode sequenceHeinrich Schuchardt
Commit 0e66c10a7d80 ("lib: vsprintf: avoid overflow printing UTF16 strings") broke the Unicode unit tests: an illegal UTF16 code point should be printed as '?'. Fixes: 0e66c10a7d80 ("lib: vsprintf: avoid overflow printing UTF16 strings") Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-02-16efi_loader: efi_dp_split_file_path() error handlingHeinrich Schuchardt
If the path passed to efi_dp_split_file_path() does not contain a reference to a file it returns EFI_OUT_OF_RESOURCES. This does not properly indicate the kind of the problem that occurred. Return EFI_INVALID_PARAMETER instead. Update function description. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-02-16efi_selftest: fix memory allocation in HII testsHeinrich Schuchardt
In efi_selftest we are in EFI land. We cannot call U-Boot library functions malloc() and free() but should use the boot time services instead. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Alexander Graf <agraf@suse.de>

2019-02-13efi_loader: fix EFI_FILE_PROTOCOL.GetInfo()Heinrich Schuchardt
We check the existence of files with fs_exist(). This function calls fs_close(). If we do not set the active block device again fs_opendir() fails and we do not set the flag EFI_FILE_DIRECTORY. Due to this error the `cd` command in the EFI shell fails. So let's add the missing set_blk_dev(fh) call.

2019-02-13efi_loader: Make HII a config optionAlexander Graf
Heinrich ran into issues with HII and iPXE which lead to #SErrors on his Odroid-C2 system. We definitely do not want to regress just yet, so let's not expose the HII protocols by default. Instead, let's make it a config option that people can play with This way, we can stabilize the code in tree without breaking any users. Once someone figures out, why this breaks iPXE (probably a NULL dereference), we can enable it by default.

2019-02-13efi_loader: debug output for HII protocolsHeinrich Schuchardt
For correct indention use EFI_PRINT() instead of debug(). For printing efi_uintn_t or size_t use the %zu or %zx format code. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2019-02-13efi_selftest: fix HII testsHeinrich Schuchardt
efi_st_printf() does not support format code %ld. Anyway the format code for size_t would be %zu which isn't supported either. We do not want any divisions to avoid invalid references to integer arithmetic routines, cf. https://gcc.gnu.org/onlinedocs/gccint/Integer-library-routines.html. As a simple remedy remove the noisy messages from the output. They are not relevant for automated testing.

2019-02-13efi_loader: GetNextVariableName() relies on REGEXHeinrich Schuchardt

2019-02-13efi_loader: fix GetNextVariableNameHeinrich Schuchardt
Our current implementation of GetNextVariableName() first collects all EFI variables. If none is found at all hexport_r() returns a zero length string terminated by \0 and the value 1 as number of bytes in the returned buffer.
