doc: replace @return by Return:

2022-01-19T17:11:34Z

Sphinx expects Return: and not @return to indicate a return value. find . -name '*.c' -exec \ sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \; find . -name '*.h' -exec \ sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \; Signed-off-by: Heinrich Schuchardt

fs: fat: check for buffer size before reading blocks

2021-10-12T20:49:21Z

This patch optimizes the commit mentioned below by avoiding running a set of commands which are useless in the case when size < mydata->sect_size and sect_count would be 0. Fixes: 5b3ddb17ba ("fs/fat/fat.c: Do not perform zero block reads if there are no blocks left") Signed-off-by: Ricardo Salveti Co-developed-by: Oleksandr Suvorov Signed-off-by: Oleksandr Suvorov

fs: fat: add file attributes to struct fs_dirent

When reading a directory in the UEFI file system we have to return file attributes and timestamps. Copy this data to the directory entry structure. Signed-off-by: Heinrich Schuchardt

fs: fat: fix file_fat_detectfs()

2021-04-10T10:00:24Z

Up to now file_fat_detectfs() did not detect some interface types like EFI, HOST, VIRTIO. Avoid duplicate code by calling blk_get_if_type_name(). The interface type now will be shown in lower case to match all other use cases. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

fs: fat: must not write directory '.' and '..'

Directories or files called '.' or '..' cannot be created or written to in any directory. Move the test to normalize_longname() to check this early. Signed-off-by: Heinrich Schuchardt

fs: fat: usage basename in file_fat_write_at, fat_mkdir

2021-02-03T08:52:51Z

This patch involves no functional change. It is just about code readability. Both in file_fat_write_at() and fat_mkdir() the incoming file or directory path are split into two parts: the parent directory and the base name. In file_fat_write_at() the value of the variable basename is assigned to the filename parameter and afterwards the variable filename is used instead of basename. It is more readable to use the variable basename and leave filename unchanged. In fat_mkdir() the base name variable is called directory. This is confusing. Call it basename like in file_fat_write_at(). This allows to rename parameter new_directory to directory in the implementation of fat_mkdir() to match the function declaration.

fs: fat: structure for name and extension

2021-01-23T06:56:53Z

The short name and extension of FAT files are stored in adjacent fields of the directory entry. For some operations like calculating a checksum or copying both fields it is preferable to treat both as one structure. Change the definition of the directory entry structure to include a structure comprising the name and the extension field. This resolves Coverity CID 316357, CID 316350, CID 316348.
