    Subject[PATCH] 32-bit UID support for 2.3.36
    Hi. I have a new version of the 32-bit UID support patches for Linux
    2.3.36.

    The patches are available at:

    http://www.engin.umich.edu/caen/systems/Linux/code/misc/2.3/20000106/

    Changes in this version:
    - updated to Linux 2.3.36

    - fix ext2 interoperability problem with old kernels:

    ext2 recycles deleted inodes without clearing out unused fields.
    This results in corrupted uids/gids when interchanging an ext2
    filesystem between a 32-bit UID kernel and an unpatched kernel.

    - back out recent change to Alpha shm, since this is fixed in new
    32-bit UID SysVIPC changes

    - glibc 2.1 patch now included with full backwards compatibility


    It is tested and working on the i386 architecture.


    Brief description of the patches:

    http://www.engin.umich.edu/caen/systems/Linux/code/misc/2.3/20000106/
    linux-arch-independ.patch

    Architecture independent changes necessary for 32-bit
    UIDs, including compatibility wrappers for old 16-bit UID
    system calls.

    linux-ipc.patch

    Support for 32-bit UIDs in SysVipc: message queues,
    semaphores, and shared memory.
    Also fixes the ABI breakage on Alpha.

    linux-ext2.patch

    Support for 32-bit UIDs in the ext2 filesystem, according
    to the HURD disk layout.

    linux-filesystems.patch

    Various patches to other filesystems to enable 32-bit
    UIDs where possible, and fix up potential problems with
    16-bit UID filesystems otherwise.

    linux-acct.patch

    Small patch to support 32-bit UIDs in the system
    accounting file.

    linux-alpha.patch
    linux-arm.patch
    linux-i386.patch
    linux-m68k.patch
    linux-mips.patch
    linux-ppc.patch
    linux-sh.patch
    linux-sparc.patch

    Architecture specific patches to enable 32-bit UID support
    via new system calls, and define the new SysVipc API.

    glibc-2.1.2-highuid.patch
    Patch against glibc 2.1 to enable use of 32-bit UIDs
    without recompiling old applications; works against 32-bit
    UID kernel or standard kernel.


    Thanks,
