  • f0ac67580   Fix ppp_deflate issues with recent zlib_inflate changes ... Browse Code »

    The last zlib_inflate update broke certain corner cases for ppp_deflate
    decompression handling. This patch fixes some logic to make things work
    properly again. Users other than ppp_deflate (the only Z_PACKET_FLUSH
    user) should be unaffected.

    Fixes bug 8405 (confirmed by Stefan)

    The recent zlib update (commit 4f3865fb57a04db7cca068fed1c15badc064a302)
    broke ppc32 zImage decompression as it tries to decompress to address zero
    and the updated zlib_inflate checks that strm->next_out isn't a null
    pointer.

    This little patch fixes it.

    43

    Upgrade the zlib_inflate implementation in the kernel from a patched
    version 1.1.3/4 to a patched 1.2.3.

    The code in the kernel is about seven years old and I noticed that the
    external zlib library's inflate performance was significantly faster (~50%)
    than the code in the kernel on ARM (and faster again on x86_32).

    For comparison the newer deflate code is 20% slower on ARM and 50% slower
    on x86_32 but gives an approx 1% compression ratio improvement. I don't
    consider this to be an improvement for kernel use so have no plans to
    change the zlib_deflate code.

    Various changes have been made to the zlib code in the kernel, the most
    significant being the extra functions/flush option used by ppp_deflate.
    This update reimplements the features PPP needs to ensure it continues to
    work.

    This code has been tested on ARM under both JFFS2 (with zlib compression
    enabled) and ppp_deflate and on x86_32. JFFS2 sees an approx. 10% real
    world file read speed improvement.

    This patch also removes ZLIB_VERSION as it no longer has a correct value.
    We don't need version checks anyway as the kernel's module handling will
    take care of that for us. This removal is also more in keeping with the
    zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've
    added something to the zlib.h header to note its a modified version.

    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!
