2018-10-16efi_loader: correct signature of GetPosition, SetPositionHeinrich Schuchardt
The UEFI spec requires that file positions are passed as u64 in GetPosition() and SetPosition(). Check if the file handle points to a directory in GetPosition(). Provide a unit test for GetPosition() and SetPosition(). Fix Coverity warning CID 184079 (CONSTANT_EXPRESSION_RESULT). Add comments.

2018-10-16efi_loader: fix relocation on x86_64Heinrich Schuchardt
Currently the relocation of the EFI runtime on x86_64 fails. This renders the EFI subsystem unusable. The ELF relocation records for x86_64 contain an addend field. Always write the function name into error messages related to the EFI runtime relocation. Break an excessively long line.

2018-09-23efi_loader: refactor efi_setup_loaded_image()Heinrich Schuchardt
Create the handle of loaded images and the EFI_LOADED_IMAGE_PROTOCOL inside efi_setup_loaded_image(). Do not use local variables. Currently we expect the loaded image handle to point to the loaded image protocol. Additionally we have appended private fields to the protocol. With the patch the handle points to a loaded image object and the private fields are added here. This matches how we handle the net and the gop object.

2018-09-23efi_loader: remove efi_exit_caches()Heinrich Schuchardt
Since GRUB patch d0c070179d4d ("arm/efi: Switch to arm64 linux loader", 2018-07-09) we do not need a workaround for GRUB on 32bit ARM anymore. So let's eliminate function efi_exit_caches(). This will require Linux distributions to update grub-efi-arm to the GRUB git HEAD (a tag containing the aforementioned GRUB patch is not available yet).

2018-09-23efi_loader: create root nodeHeinrich Schuchardt
Currently we assign a lot of protocols to loaded images though these protocols are not related to them. Instead they should be installed on a separate handle. Via the device path it is the parent to the devices like the network adapter. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: avoid out of bound access in efi_get_variable()Heinrich Schuchardt
In efi_get_variable() a string is longer than the allocated space which results in overwriting the linked list of malloc(). The prefixes used for variables are 41 characters long, e.g. efi_67029eb5-0af2-f6b1-da53-fcb566dd1ce6_ Change PREFIX_LEN to 41.

2018-09-23efi_loader: query serial console size reliablyHeinrich Schuchardt
Not all terminals understand CSI [18t for querying the console size. We should adhere to escape sequences documented in the console_codes manpage and the ECMA-48 standard. So here we follow a different approach. We position the cursor to the bottom right and query its position. Before leaving the function we restore the original cursor position.

2018-09-23efi_loader: Merge memory map entriesAlexander Graf
We currently do not combine memory entries that are adjacent and have the same attributes. The problem with that is that our memory map can easily grow multiple hundreds of entries in a simple UEFI Shell environment. So let's make sure we always combine all entries to make the memory map as small as possible. That way every other piece of code that loops through it should also gain some nice speed ups.

2018-09-23efi_loader: check parameter new_handle of efi_file_open()Heinrich Schuchardt

2018-09-23efi_loader: terminal left upper corner is [1, 1]Heinrich Schuchardt
For the VT102 and the Linux console the left upper corner is [1, 1]. EFI uses [0, 0] as left upper corner. Check parameters of the SetCursorPosition() service. Use CSI H like EDK2 for positioning. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: more debug info for efi_file_getinfo()Heinrich Schuchardt

2018-09-23efi_loader: loosen check of parameters of efi_file_open()Heinrich Schuchardt
The UEFI spec requires that attributes are only set for when EFI_FILE_MODE_CREATE is set in open_mode. The SCT tries to read a directory with EFI_FILE_DIRECTORY.

In int-ll64.h, we always use the following typedefs: typedef unsigned int u32; typedef unsigned long uintptr_t; typedef unsigned long long u64; This does not need to match to the compiler's <inttypes.h>. Do not include it. The use of PRI* makes the code super-ugly. You can simply use "l" for printing uintptr_t, "ll" for u64, and no modifier for u32.
