[PATCH] ipc: add generic struct ipc_ids seq_file iteration

2005-09-07T23:57:25Z

The following two patches convert /proc/sysvipc/* to use seq_file. This gives us the following: - Self-consistent IPC records in proc. - O(n) reading of the files themselves. This patch: Add a generic method for ipc types to be displayed using seq_file. This patch abstracts out seq_file iterating over struct ipc_ids into ipc/util.c Signed-off-by: Mike Waychison Cc: Manfred Spraul Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] xtensa: remove old syscalls

2005-07-12T23:01:01Z

This patch fixes some minor bugs introduced by the previous patch (remove old syscalls). Both patches remove the obsolete syscalls. The changes in this patch were suggested by Arnd Bergmann. The vmlinux.lds.S changes are required for the latest gcc/binutils. Signed-off-by: Chris Zankel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] RCU: eliminating explicit memory barriers from SysV IPC

2004-10-28T01:28:37Z

This patch uses the rcu_assign_pointer() API to eliminate a number of explicit memory barriers from the SysV IPC code that uses RCU. It also restructures the ipc_ids structure so that the array size is stored in the same memory block as the array itself (see the new struct ipc_id_ary). This prevents the race that the earlier code was subject to, where a reader could see a mismatch between the size and the actual array. With the size stored with the array, the possibility of mismatch is eliminated -- with out the need for careful ordering and explicit memory barriers. This has been tested successfully on i386 and ppc64. Signed-off-by: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ipc: Add refcount to ipc_rcu_alloc

2004-08-23T05:40:37Z

The lifetime of the ipc objects (sem array, msg queue, shm mapping) is controlled by kern_ipc_perms->lock - a spinlock. There is no simple way to reacquire this spinlock after it was dropped to schedule()/kmalloc/copy_{to,from}_user/whatever. The attached patch adds a reference count as a preparation to get rid of sem_revalidate(). Signed-Off-By: Manfred Spraul Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] posix message queues: code move

2004-04-12T05:53:50Z

From: Manfred Spraul cleanup of sysv ipc as a preparation for posix message queues: - replace !CONFIG_SYSVIPC wrappers for copy_semundo and exit_sem with static inline wrappers. Now the whole ipc/util.c file is only used if CONFIG_SYSVIPC is set, use makefile magic instead of #ifdef. - remove the prototypes for copy_semundo and exit_sem from kernel/fork.c - they belong into a header file. - create a new msgutil.c with the helper functions for message queues. - cleanup the helper functions: run Lindent, add __user tags.

[PATCH] PA-RISC needs IPC64 structs

2004-02-06T11:44:47Z

PA-RISC also uses the 64-bit version of the IPC structs.

[PATCH] Fix IPC ABI for AMD64

2003-07-01T09:35:22Z

AMD64 like IA64 needs to force IPC_64 in the IPC functions. This makes 2.5 compatible with 2.4 again.

[PATCH] uninlining in ipc/*
