This patch includes more IPC changes, and a "final" proposal for new
msqid_ds, semid_ds, and shmid_ds structures. Now there is padding space
available on all platforms for:
32-bit pid_t
64-bit time_t
32-bit mode_t
32-bit 'seq' in ipc_perm
32-bit or 64-bit message sizes for message queues
The ipc_perm structure is now also broken out architecture-by-architecture
into include/asm-[arch]/ipc.h, along with the msqid_ds, semid_ds, and
shmid_ds structures.
The patches are available at:
http://www.engin.umich.edu/caen/systems/Linux/code/misc/2.3/19991123b/
Changes in this version:
- struct ipc_perm is now broken out on an architecture-by-
architecture basis, pad space is now included for a 32-bit
mode_t and seq on all architectures.
- include/asm-m68k/shm.h file was clobbered by previous patch;
now fixed
- sem_perm.seq field now copied properly by semctl() and
IPC_OLDSTAT, SEM_OLDSTAT
As always, the patches are tested and working on i386.
In order to use 32-bit UIDs you need the following patches from the above
URL:
linux-acct.patch
linux-arch-independ.patch
linux-ext2.patch
linux-ipc.patch
linux-filesystems.patch
as well as a patch for your particular architecture:
linux-alpha.patch
linux-arm.patch
linux-i386.patch
linux-m68k.patch
linux-mips.patch
linux-ppc.patch
linux-sh.patch
linux-sparc.patch
linux-sparc64.patch
Still broken with these patches:
- sparc64 architecture.
