  • 045ddc899   NLS: raname "maxlen" to "maxout" in UTF conversion routines ... Browse Code »

    As requested by NamJae Jeon, this patch (as1503) changes the name of
    the "maxlen" parameters to "maxout" in the various UTF conversion
    routines. This should make the role of that parameter more clear.

    The patch also renames the "len" parameters to "inlen", for the same
    reason.

  • 0720a06a7   NLS: improve UTF8 -> UTF16 string conversion routine ... Browse Code »

    The utf8s_to_utf16s conversion routine needs to be improved. Unlike
    its utf16s_to_utf8s sibling, it doesn't accept arguments specifying
    the maximum length of the output buffer or the endianness of its
    16-bit output.

    This patch (as1501) adds the two missing arguments, and adjusts the
    only two places in the kernel where the function is called. A
    follow-on patch will add a third caller that does utilize the new
    capabilities.

    The two conversion routines are still annoyingly inconsistent in the
    way they handle invalid byte combinations. But that's a subject for a
    different patch.

  • 6d729e44a   fs: Make unload_nls() NULL pointer safe ... Browse Code »

    Most call sites of unload_nls() do:
    if (nls)
    unload_nls(nls);

    Check the pointer inside unload_nls() like we do in kfree() and
    simplify the call sites.

  • 67638e404   fat/nls: Fix handling of utf8 invalid char ... Browse Code »

    With utf8 option, vfat allowed the duplicated filenames.

    Normal nls returns -EINVAL for invalid char. But utf8s_to_utf16s()
    skipped the invalid char historically.

    So, this changes the utf8s_to_utf16s() directly to return -EINVAL for
    invalid char, because vfat is only user of it.

    mkdir /mnt/fatfs
    FILENAME=`echo -ne "invalidutf8char_\\0341_endofchar"`
    echo "Using filename: $FILENAME"
    dd if=/dev/zero of=fatfs bs=512 count=128
    mkdosfs -F 32 fatfs
    mount -o loop,utf8 fatfs /mnt/fatfs
    touch "/mnt/fatfs/$FILENAME"
    umount /mnt/fatfs
    mount -o loop,utf8 fatfs /mnt/fatfs
    touch "/mnt/fatfs/$FILENAME"
    ls -l /mnt/fatfs
    umount /mnt/fatfs

    ---- And the output is:

    Using filename: invalidutf8char_\0341_endofchar

    128+0 records out

  • 74675a585   NLS: update handling of Unicode ... Browse Code »

    This patch (as1239) updates the kernel's treatment of Unicode. The
    character-set conversion routines are well behind the current state of
    the Unicode specification: They don't recognize the existence of code
    points beyond plane 0 or of surrogate pairs in the UTF-16 encoding.

    The old wchar_t 16-bit type is retained because it's still used in
    lots of places. This shouldn't cause any new problems; if a
    conversion now results in an invalid 16-bit code then before it must
    have yielded an undefined code.

    Difficult-to-read names like "utf_mbstowcs" are replaced with more
    transparent names like "utf8s_to_utf16s" and the ordering of the
    parameters is rationalized (buffer lengths come immediate after the
    pointers they refer to, and the inputs precede the outputs).
    Fortunately the low-level conversion routines are used in only a few
    places; the interfaces to the higher-level uni2char and char2uni
    methods have been left unchanged.

  • 905c02acb   nls: utf8_wcstombs: fix buffer overflow ... Browse Code »

    utf8_wcstombs forgot to include one-byte UTF-8 characters when
    calculating the output buffer size, i.e., theoretically, it was possible
    to overflow the output buffer with an input string that contains enough
    ASCII characters.

    In practice, this was no problem because the only user so far (VFAT)
    always uses a big enough output buffer.

    When utf8_wcstombs encounters a character that cannot be encoded, we
    must not decrease the remaining output buffer size because nothing has

    Add const modifiers to a few struct nls_table's member pointers in
    include/linux/nls.h and adds a lot of const's in fs/nls/*.c files.

    Resulting changes as visible by size:

    text data bss dec hex filename
    113612 481216 2368 597196 91ccc nls.org/built-in.o
    593548 3296 288 597132 91c8c nls/built-in.o

    Apparently compiler managed to optimize code a bit better
    because of const-ness.

    No other changes are made.

  • f46ba2235   [PATCH] fs: make nls_cp936.c handle some U00XY characters and U20AC correctly ... Browse Code »

    Twenty characters in cp936 are not correctly handled. They're all in the
    U00 plane. nls_cp936 converts all U00XY to XY but this is not correct for
    some characters.(e.g. U00B7 -> A1A4, U00A8 -> A1A7).

    This problem is fixed by generating u2c_00 based on all c2u_xx and changing
    uni2char() to give U00 plane a special handling. The "€"(U20AC,80 in
    cp936) is also be handled properly.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
