  • 5e8f98319   FAT: implement fat_set_blk_dev(), convert cmd_fat.c ... Browse Code »

    This makes the FAT filesystem API more consistent with other block-based
    filesystems. If in the future standard multi-filesystem commands such as
    "ls" or "load" are implemented, having FAT work the same way as other
    filesystems will be necessary.

    Convert cmd_fat.c to the new API, so the code looks more like other files
    implementing the same commands for other filesystems.

  • 1170e634d   FAT: Make it possible to read from any file position ... Browse Code »

    When storage devices contain files larger than the embedded RAM, it is
    useful to be able to read these files by chunks, e.g. for a software
    update to the embedded NAND Flash from an external storage device (USB
    stick, SD card, etc.).

    Hence, this patch makes it possible by adding a new FAT API to read
    files from a given position. This patch also adds this feature to the
    fatload command.

  • 1d90c3b45   fat: fix FAT sector offsets overflow on large FAT partitions ... Browse Code »

    This patch fixes several issues where sector offsets can overflow due
    to being limited to 16-bits. The cases where an overflow can happen
    when accessing large FAT32 partitions are:

    - length of FAT in sectors
    - start sector of root directory
    - the sector of the first cluster

    These issues were observed when reading files from a 64GB FAT32
    filesystem.

    1

    In some cases, saving data in RAM as a file with FAT format is required.
    This patch allows the file to be written in FAT formatted partition.

    The usage is similar with reading a file.
    First, fat_register_device function is called before file_fat_write function
    in order to set target partition.
    Then, file_fat_write function is invoked with desired file name,
    start ram address for writing data, and file size.

  • 025421eab   fat: replace LINEAR_PREFETCH_SIZE with PREFETCH_BLOCKS ... Browse Code »

    Currently in do_fat_read() when reading FAT sectors, we have to divide down
    LINEAR_PREFETCH_SIZE by the sector size, whereas it's defined as 2 sectors
    worth of bytes. In order to avoid redundant multiplication/division, introduce
    #define PREFETCH_BLOCKS instead of #define LINEAR_PREFETCH_SIZE.

    Apple iPod nanos have sector sizes of 2 or 4 KiB, which crashes U-Boot when it
    tries to read the boot sector into 512-byte buffer situated on stack. Make the
    FAT code indifferent to the sector size.

  • 3831530dc   VFAT: fix processing of scattered long file name entries ... Browse Code »

    The U-Boot code has the following bugs related to the processing of Long File
    Name (LFN) entries scattered across several clusters/sectors :

    1) get_vfatname() function is designed to gather scattered LFN entries by
    cluster chain processing - that doesn't work for FAT12/16 root directory.
    In other words, the function expects the following input data:
    1.1) FAT32 directory (which is cluster chain based);
    OR
    1.2) FAT12/16 non-root directory (which is also cluster chain based);
    OR
    1.3) FAT12/16 root directory (allocated as contiguous sectors area), but
    all necessary information MUST be within the input buffer of filesystem cluster
    size (thus cluster-chain jump is never initiated).

    In order to accomplish the last condition, root directory parsing code in
    do_fat_read() uses the following trick: read-out cluster-size block, process
    only first sector (512 bytes), then shift 512 forward, read-out cluster-size
    block and so on. This works great unless cluster size is equal to 512 bytes
    (in a case you have a small partition), or long file name entries are scattered
    across three sectors, see 4) for details.

    2) Despite of the fact that get_vfatname() supports FAT32 root directory
    browsing, do_fat_read() function doesn't send current cluster number correctly,
    so root directory look-up doesn't work correctly.

    3) get_vfatname() doesn't gather scattered entries correctly also is the case
    when all LFN entries are located at the end of the source cluster, but real
    directory entry (which must be returned) is at the only beginning of the
    next one. No error detected, the resulting directory entry returned contains
    a semi-random information (wrong size, wrong start cluster number and so on)
    i.e. the entry is not accessible.

    4) LFN (VFAT) allows up to 20 entries (slots) each containing 26 bytes (13
    UTF-16 code units) to represent a single long file name i.e. up to 520 bytes.
    U-Boot allocates 256 bytes buffer instead, i.e. 10 or more LFN slots record
    may cause buffer overflow / memory corruption.
    Also, it's worth to mention that 20+1 slots occupy 672 bytes space which may
    take more than one cluster of 512 bytes (medium-size FAT32 or small FAT16
    partition) - get_vfatname() function doesn't support such case as well.

    The patch attached fixes these problems in the following way:
    - keep using 256 bytes buffer for a long file name, but safely prevent a
    possible buffer overflow (skip LFN processing, if it contains 10 or more
    slots).

    - explicitly specify FAT12/16 root directory parsing buffer size, instead
    of relying on cluster size. The value used is a double sector size (to store
    current sector and the next one). This fixes the first problem and increases
    performance on big FAT12/16 partitions;

    - send current cluster number (FAT32) to get_vfatname() during root
    directory processing;

    - use LFN counter to seek the real directory entry in get_vfatname() - fixes the
    third problem;

    - skip deleted entries in the root directory (to prevent bogus buffer
    overflow detection and LFN counter steps).

    Note: it's not advised to split up the patch, because a separate part may
    operate incorrectly.

  • 3c2c2f427   Remove non-ascii characters from fat code ... Browse Code »

    This code contains some non-ascii characters in comment lines and code.
    Most editors do not display those characters properly and editing those
    files results always in diffs at these places which are usually not required
    to be changed at all. This is error prone.

    So, remove those weird characters and replace them by normal C-style
    equivalents for which the proper defines were already in the header.
