| |
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,
Chris Wing wingc@engin.umich.edu
