efi_loader: loosen buffer parameter check in efi_file_read_int

2021-05-18T10:36:12+00:00

This is same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1733817, but that fix was wrongly partial reverted. When reading a directory, EFI_BUFFER_TOO_SMALL should be returned when the supplied buffer is too small, so a use-case is to call EFI_FILE_PROTOCOL.Read() with *buffer_size=0 and buffer=NULL to obtain the needed size before doing the actual read. So remove the check only for directory reading, file reading already do the check by itself.

efi_loader: Add helper functions for EFI

2021-03-25T19:14:25+00:00

A following patch introduces a different logic for loading initrd's based on the EFI_LOAD_FILE2_PROTOCOL. Since similar logic can be applied in the future for other system files (i.e DTBs), let's add some helper functions which will retrieve and parse file paths stored in EFI variables.

efi_loader: incorrect buffer size in efi_file_setinfo()

efi_loader: loosen buffer parameter check in efi_file_read

2020-07-22T10:32:41+00:00

When reading a directory, EFI_BUFFER_TOO_SMALL should be returned when the supplied buffer is too small, so a use-case is to call efi_file_read with *buffer_size=0 and buffer=NULL to obtain the needed size before doing the actual read. So move the buffer!=NULL check to after the buffer size has been checked. This fix allows the Redhat shim fallback to run and e.g. Fedora 32 now boots out of the box.

We should not be using typedefs and these make it harder to use forward declarations (to reduce header file inclusions). Drop the typedef. Signed-off-by: Simon Glass

efi_loader: adjust file system info

2020-01-07T17:08:20+00:00

When the GetInfo() method of the EFI_FILE_PROTOCOL is called to retrieve the file system info we claim that the volume is read only and has no free space. This leads to failures in programs that check this information before writing to the volume like SCT's InstallSct.efi. Currently there is no function to determine these parameters in U-Boot. So let's return optimistic values: Return that the volume is writable. Return the volume size as free space. Signed-off-by: Heinrich Schuchardt
