| 18955cf | Mike Stroyan | 30 November 2005, 00:12:55 UTC | [IPV4] tcp/route: Another look at hash table sizes The tcp_ehash hash table gets too big on systems with really big memory. It is worse on systems with pages larger than 4KB. It wastes memory that could be better used. It also makes the netstat command slow because reading /proc/net/tcp and /proc/net/tcp6 needs to go through the full hash table. The default value should not be larger for larger page sizes. It seems that the effect of page size is an unintended error dating back a long time. I also wonder if the default value really should be a larger fraction of memory for systems with more memory. While systems with really big ram can afford more space for hash tables, it is not clear to me that they benefit from increasing the allocation ratio for this table. The amount of memory allocated is determined by net/ipv4/tcp.c:tcp_init and mm/page_alloc.c:alloc_large_system_hash. tcp_init calls alloc_large_system_hash passing parameters- bucketsize=sizeof(struct tcp_ehash_bucket) numentries=thash_entries scale=(num_physpages >= 128 * 1024) ? (25-PAGE_SHIFT) : (27-PAGE_SHIFT) limit=0 On i386, PAGE_SHIFT is 12 for a page size of 4K On ia64, PAGE_SHIFT defaults to 14 for a page size of 16K The num_physpages test above makes the allocation take a larger fraction of the total memory on systems with larger memory. The threshold size for a i386 system is 512MB. For an ia64 system with 16KB pages the threshold is 2GB. For smaller memory systems- On i386, scale = (27 - 12) = 15 On ia64, scale = (27 - 14) = 13 For larger memory systems- On i386, scale = (25 - 12) = 13 On ia64, scale = (25 - 14) = 11 For the rest of this discussion, I'll just track the larger memory case. The default behavior has numentries=thash_entries=0, so the allocated size is determined by either scale or by the default limit of 1/16 of total memory. In alloc_large_system_hash- | numentries = (flags & HASH_HIGHMEM) ? nr_all_pages : nr_kernel_pages; | numentries += (1UL << (20 - PAGE_SHIFT)) - 1; | numentries >>= 20 - PAGE_SHIFT; | numentries <<= 20 - PAGE_SHIFT; At this point, numentries is pages for all of memory, rounded up to the nearest megabyte boundary. | /* limit to 1 bucket per 2^scale bytes of low memory */ | if (scale > PAGE_SHIFT) | numentries >>= (scale - PAGE_SHIFT); | else | numentries <<= (PAGE_SHIFT - scale); On i386, numentries >>= (13 - 12), so numentries is 1/8196 of bytes of total memory. On ia64, numentries <<= (14 - 11), so numentries is 1/2048 of bytes of total memory. | log2qty = long_log2(numentries); | | do { | size = bucketsize << log2qty; bucketsize is 16, so size is 16 times numentries, rounded down to a power of two. On i386, size is 1/512 of bytes of total memory. On ia64, size is 1/128 of bytes of total memory. For smaller systems the results are On i386, size is 1/2048 of bytes of total memory. On ia64, size is 1/512 of bytes of total memory. The large page effect can be removed by just replacing the use of PAGE_SHIFT with a constant of 12 in the calls to alloc_large_system_hash. That makes them more like the other uses of that function from fs/inode.c and fs/dcache.c Signed-off-by: David S. Miller <davem@davemloft.net> | 30 November 2005, 00:12:55 UTC |

| ea164d7 | Andrea Arcangeli | 28 November 2005, 21:44:15 UTC | [PATCH] shrinker->nr = LONG_MAX means deadlock for icache With Andrew Morton <akpm@osdl.org> The slab scanning code tries to balance the scanning rate of slabs versus the scanning rate of LRU pages. To do this, it retains state concerning how many slabs have been scanned - if a particular slab shrinker didn't scan enough objects, we remember that for next time, and scan more objects on the next pass. The problem with this is that with (say) a huge number of GFP_NOIO direct-reclaim attempts, the number of objects which are to be scanned when we finally get a GFP_KERNEL request can be huge. Because some shrinker handlers just bail out if !__GFP_FS. So the patch clamps the number of objects-to-be-scanned to 2* the total number of objects in the slab cache.

We detect a re-add by looking at saved_raid_disk. For raid1, it doesn't matter which disk it was, only whether or not it was an active device. The old code being removed set a value of 'mirror' which was then ignored, so it can go. The changed code performs the correct check. For raid6, if there are two missing devices, make sure we chose the right slot on --re-add rather than always the first slot.

| 22dfdf5 | NeilBrown | 28 November 2005, 21:44:09 UTC | [PATCH] md: improve read speed to raid10 arrays using 'far copies' raid10 has two different layouts. One uses near-copies (so multiple copies of a block are at the same or similar offsets of different devices) and the other uses far-copies (so multiple copies of a block are stored a greatly different offsets on different devices). The point of far-copies is that it allows the first section (normally first half) to be layed out in normal raid0 style, and thus provide raid0 sequential read performance. Unfortunately, the read balancing in raid10 makes some poor decisions for far-copies arrays and you don't get the desired performance. So turn off that bad bit of read_balance for far-copies arrays. With this patch, read speed of an 'f2' array is comparable with a raid0 with the same number of devices, though write speed is ofcourse still very slow.

The problem appears to be a very big task that is holding the swap token, and the VM has a very hard time finding any other page in the system that is swappable. Instead of ignoring the swap token when sc->priority reaches 0, we could simply take the swap token away from the memory hog and make sure we don't give it back to the memory hog for a few seconds.

| 3148890 | Nick Piggin | 28 November 2005, 21:44:03 UTC | [PATCH] mm: __alloc_pages cleanup fix I believe this patch is required to fix breakage in the asynch reclaim watermark logic introduced by this patch: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=7fb1d9fca5c6e3b06773b69165a73f3fb786b8ee Just some background of the watermark logic in case it isn't clear... Basically what we have is this: --- pages_high | | (a) | --- pages_low | | (b) | --- pages_min | | (c) | --- 0 Now when pages_low is reached, we want to kick asynch reclaim, which gives us an interval of "b" before we must start synch reclaim, and gives kswapd an interval of "a" before it need go back to sleep. When pages_min is reached, normal allocators must enter synch reclaim, but PF_MEMALLOC, ALLOC_HARDER, and ALLOC_HIGH (ie. atomic allocations, recursive allocations, etc.) get access to varying amounts of the reserve "c".

| 91f4ab0 | Hirokazu Takata | 28 November 2005, 21:43:58 UTC | [PATCH] m32r: Fix sys_tas() syscall This patch fixes a deadlock problem of the m32r SMP kernel. In the m32r kernel, sys_tas() system call is provided as a test-and-set function for userspace, for backward compatibility. In some multi-threading application program, deadlocks were rarely caused at sys_tas() funcion. Such a deadlock was caused due to a collision of __pthread_lock() and __pthread_unlock() operations. The "tas" syscall is repeatedly called by pthread_mutex_lock() to get a lock, while a lock variable's value is not 0. On the other hand, pthead_mutex_unlock() sets the lock variable to 0 for unlocking. In the previous implementation of sys_tas() routine, there was a possibility that a unlock operation was ignored in the following case: - Assume a lock variable (*addr) was equal to 1 before sys_tas() execution. - __pthread_unlock() operation is executed by the other processor and the lock variable (*addr) is set to 0, between a read operation ("oldval = *addr;") and the following write operation ("*addr = 1;") during a execution of sys_tas(). In this case, the following write operation ("*addr = 1;") overwrites the __pthread_unlock() result, and sys_tas() fails to get a lock in the next turn and after that. According to the attatched patch, sys_tas() returns 0 value in the next turn and deadlocks never happen.

This caused some NULL pointer dereference in kernel/workqueue.c because for single_threaded workqueue's, it hardcoded the cpu to 0.

The lock is already held during cpu_up() and cpu_down() calls when the notify calls are broadcast to registered clients. Ideally if possible, we could disable_preempt() at the highest caller and make sure we dont sleep in the path down in cpufreq->driver_target() calls but the calls are so intertwined and cumbersome to cleanup. Hence we consistently use lock_cpu_hotplug() and unlock_cpu_hotplug() in all places. - Removed export of cpucontrol semaphore and made it static. - removed explicit uses of up/down with lock_cpu_hotplug() so we can keep track of the the callers in same thread context and just keep refcounts without calling a down() that causes a deadlock. - Removed current_in_hotplug() uses - Removed PF_HOTPLUG_CPU in sched.h introduced for the current_in_hotplug() temporary workaround. Tested with insmod of cpufreq_stat.ko, and logical online/offline to make sure we dont have any hang situations.

It allows a VM area to contain an arbitrary range of page table entries that the VM never touches, and never considers to be normal pages. Any user of "remap_pfn_range()" automatically gets this new functionality, and doesn't even have to mark the pages reserved or indeed mark them any other way. It just works.

| b37b03b | Trond Myklebust | 25 November 2005, 22:10:06 UTC | NFS: Fix a spinlock recursion inside nfs_update_inode() In cases where the server has gone insane, nfs_update_inode() may end up calling nfs_invalidate_inode(), which again calls stuff that takes the inode->i_lock that we're already holding. In addition, given the sort of things we have in NFS these days that need to be cleaned up on inode release, I'm not sure we should ever be calling make_bad_inode(). Fix up spinlock recursion, and limit nfs_invalidate_inode() to clearing the caches, and marking the inode as being stale. Thanks to Steve Dickson <SteveD@redhat.com> for spotting this.

| 5edf71a | Russell King | 25 November 2005, 15:52:51 UTC | [ARM] Do not call flush_tlb_kernel_range() with IRQs disabled. We must not call TLB maintainence operations with interrupts disabled, otherwise we risk a lockup in the SMP IPI code. This means that consistent_free() can not be called from a context with IRQs disabled. In addition, we must not hold the lock in consistent_free when we call flush_tlb_kernel_range(). However, we must continue to prevent consistent_alloc() from re-using the memory region until we've finished tearing down the mapping and dealing with the TLB. Therefore, leave the vm_region entry in the list, but mark it inactive before dropping the lock and starting the tear-down process. After the mapping has been torn down, re-acquire the lock and remove the entry from the list. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> | 25 November 2005, 15:52:51 UTC |
