Ext4Pkg: Check VolumeName allocation correctness in Ext4GetVolumeName

2023-02-08T16:23:58+00:00

Missing check in some cases leads to failed StrCpyS call in Ext4GetVolumeLabelInfo. Also correct condition that checks Inode pointer for being NULL in Ext4AllocateInode Cc: Marvin Häuser Cc: Pedro Falcato Cc: Vitaly Cheptsov Fixes: cfbbae595eec ("Ext4Pkg: Add handling of EFI_FILE_SYSTEM_VOLUME_LABEL GetInfo().")

Ext4Pkg: Check that source file is directory in Ext4OpenInternal

2023-02-08T16:23:58+00:00

This check already present in the while loop below, but absent for cases when input file is nameless, so to handle assertion in Ext4ReadFile we need to add it at the top of function Cc: Marvin Häuser Cc: Pedro Falcato Cc: Vitaly Cheptsov Fixes: d9ceedca6c8f ("Ext4Pkg: Add Ext4Dxe driver.")

Ext4Pkg: Add base containing record macro for EXT4_FILE

2022-09-15T20:58:56+00:00

We shouldn't use direct casts, because in the future it could break the code, so using BASE_CR would be safe against possible structure changes and rearrangements Cc: Marvin Häuser Cc: Pedro Falcato Cc: Vitaly Cheptsov Signed-off-by: Savva Mitrofanov Reviewed-by: Marvin Häuser Reviewed-by: Pedro Falcato

Ext4Pkg: Add symbolic links support

2022-09-15T20:58:30+00:00

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3677 Provided support for symlink file type. Added routine which allows reading and following them through recursive open() call. As a security meausure implemented simple symlink loop check with nest level limit equal 8. Also this patch moves Ext4Open functionality to internal routine.

Ext4Pkg: Add a directory entry tree.

2021-08-24T01:47:18+00:00

This helps us track directories and directory entries, which helps us getting a general idea of how the filesystem looks. In the future, it might serve as a directory cache. Right now, it only lets us know which name "." and ".." may refer to, which fixes a EFI_FILE_PROTOCOL::GetInfo() bug that got triggered by ShellPkg, in some MdePkg code.
