  • 04735e9c5   Fix ext2/ext4 filesystem accesses beyond 2TiB ... Browse Code »

    With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
    which is required to represent block numbers for storage devices that
    exceed 2TiB (the block size usually is 512B), e.g. recent hard drives

    We now use lbaint_t for partition offset to reflect the lbaint_t change,
    and access partitions beyond or crossing the 2.1TiB limit.
    This required changes to signature of ext4fs_devread(), and type of all
    variables relatives to block sector.

    ext2/ext4 fs uses logical block represented by a 32 bit value. Logical
    block is a multiple of device block sector. To avoid overflow problem
    when calling ext4fs_devread(), we need to cast the sector parameter.

  • 67cd4a634   disk: Fix possible out-of-bounds access in part_efi.c ... Browse Code »

    Make sure to never access beyond bounds of either EFI partition name
    or DOS partition name. This situation is happening:

    part.h: disk_partition_t->name is 32-byte long
    part_efi.h: gpt_entry->partition_name is 36-bytes long

    The loop in part_efi.c copies over 36 bytes and thus accesses beyond
    the disk_partition_t->name .

    Fix this by picking the shortest of source and destination arrays and
    make sure the destination array is cleared so the trailing bytes are
    zeroed-out and don't cause issues with string manipulation.

  • 4715a8113   disk: part_efi: fix regression due to incorrect buffer usage ... Browse Code »

    Commit deb5ca80275e8cfa74d5680b41204e08a095eca5 "disk: part_efi: fix
    **pgpt_pte == NULL" modified the code to pass "&gpt_head" to
    is_gpt_valid() rather than the previous "gpt_head". However, gpt_head
    is a pointer to the buffer, not the actual buffer, since it was allocated
    using ALLOC_CACHE_ALIGN_BUFFER. This caused is_gpt_valid() to read the
    disk block onto the stack rather than into the buffer, causing the
    code to fail.

    This change reverts that portion of the commit mentioned above.

  • f75dd584c   part_efi: dcache: allocate cacheline aligned buffers ... Browse Code »

    Currently part_efi.c allocates buffers for the gpt_header, the
    legacy_mbr, and the pte (partition table entry) that may be
    incorrectly aligned for DMA operations.

    This patch uses ALLOC_CACHE_ALIGN_BUFFER for the stack allocated
    buffers and memalign to replace the malloc of the pte.

    Previous output:
    Marvell>> mmc part

    Partition Map for MMC device 1 -- Partition Type: EFI

    Part Start LBA End LBA
    gpt1 0x8C00 0xCBFF

    gpt3 0x57C00 0xA2BFF
    gpt4 0xA2C00 0xECBFDE

    With the patch, the output becomes:

  • 75eb82ec7   mflash: Initial mflash support ... Browse Code »

    Mflash is fusion memory device mainly targeted consumer eletronic and
    mobile phone.
    Internally, it have nand flash and other hardware logics and supports
    some different operation (ATA, IO, XIP) modes.

    IO mode is custom mode for the host that doesn't have IDE interface.
    (Many mobile targeted SoC doesn't have IDE bus)

    This driver support mflash IO mode.

    Followings are brief descriptions about IO mode.

    1. IO mode based on ATA protocol and uses some custom command. (read
    confirm, write confirm)
    2. IO mode uses SRAM bus interface.
