2019-02-16efi_loader: comments for efi_file_from_path()Heinrich Schuchardt
Add more comments for efi_file_from_path(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.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: use u16* for file nameHeinrich Schuchardt
UTF-16 strings in our code should all be u16 *. Fix an inconsistency for file names which may lead to a warning for printf("%ls", ). Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2019-01-14efi_loader: Add a wchar_t cast in efi_file_open()Simon Glass
The printf() string here is not actually correct. Add a cast to avoid a warning when checking is enabled. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-12-02efi_loader: use u16* for UTF16 stringsHeinrich Schuchardt
We should be consistent in the types that we use to store Unicode strings. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-10-16efi_loader: superfluous statement in is_dir()Heinrich Schuchardt
When is_dir() is called we have already execute set_blk_dev(fh). So don't call it again. This fixes CoverityScan CID 184093. Reported-by: Tom Rini <trini@konsulko.com> Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
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. Fixes: b6dd57773719 ("efi_loader: use correct types in EFI_FILE_PROTOCOL") Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: check parameter new_handle of efi_file_open()Heinrich Schuchardt
We should not check parameter file twice. We should check parameter new_handle. 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
efi_file_getinfo() is called with a GUID. In EFI_ENTRY use %pUl as format type. This way the GUID is printed in debug mode. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi: Correct the operation of efi_file_write()Simon Glass
We should not directly cast between pointers and addresses since it breaks sandbox. Fix this and simplify the code in file_read(). Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
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. As EDK2 allows this we should not be more strict. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: provide description of file_open()Heinrich Schuchardt
Replace urban slang by proper description. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: check parameters of efi_file_open()Heinrich Schuchardt
Check the parameters of efi_file_open(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: implement a file deleteAKASHI Takahiro
'Delete' will be implemented here by calling fs_unlink() which relies on underlying file system's implementation. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: file: support creating a directoryAKASHI Takahiro
In efi world, there is no obvious "mkdir" interface, instead, Open() with EFI_FILE_MODE_CREATE in mode parameter and EFI_FILE_DIRECTORY in attributes parameter creates a directory. In this patch, efi_file_open() is extended so as to accept such a combination of parameters and call u-boot's mkdir interface for expected action.

2018-09-23efi_loader: rename utf16_strlen, utf16_strnlenHeinrich Schuchardt
The function names utf16_strlen() and utf16_strnlen() are misnomers. The functions do not count utf-16 characters but non-zero words. So let's rename them to u16_strlen and u16_strnlen(). In utf16_dup() avoid assignment in if clause. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23efi_loader: Pass address to fs_read()Alexander Graf
The fs_read() function wants to get an address rather than the pointer to a buffer. So let's convert the passed buffer from pointer back a the address to make efi_loader on sandbox happier.

2018-05-10SPDX: Convert a few files that were missed beforeTom Rini
As part of the main conversion a few files were missed. These files had additional whitespace after the '*' and before the SPDX tag and my previous regex was too strict. This time I did a grep for all SPDX tags and then filtered out anything that matched the correct styles.

2018-04-05efi_loader: implement EFI_FILE_SYSTEM_INFOHeinrich Schuchardt
Implement the information type EFI_FILE_SYSTEM_INFO in the service GetInfo() of the EFI_FILE_PROTOCOL. The volume label is not available in U-Boot. As a work-around use the partition name instead. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-04-05efi_loader: use const for GUIDs in the EFI_FILE_PROTOCOLHeinrich Schuchardt

2018-04-04efi_loader: use correct types in EFI_FILE_PROTOCOLHeinrich Schuchardt
In the EFI_FILE_PROTOCOL buffer sizes and positions are passed as UINTN and not as u64. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2017-09-20efi_loader: add file/filesys supportRob Clark
fallback.efi (and probably other things) use UEFI's simple-file-system protocol and file support to search for OS's to boot. Signed-off-by: Rob Clark <robdclark@gmail.com> [agraf: whitespace fixes, unsigned fixes] Signed-off-by: Alexander Graf <agraf@suse.de>
