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,
