* [PATCH] Fix compiler warning in driver core for CONFIG_HOTPLUG=NRussell King2006-02-06

* [PPP]: Fixed hardware RX checksum handlingHerbert Xu2006-02-05
| | | | | | | | | | | | | When we pull the PPP protocol off the skb, we forgot to update the hardware RX checksum. This may lead to messages such as dsl0: hw csum failure. Similarly, we need to clear the hardware checksum flag when we use the existing packet to store the decompressed result.

* mm/slab.c (non-NUMA): Fix compile warning and clean up codeLinus Torvalds2006-02-05
| | | | | | | | | | | | | | The non-NUMA case would do an unmatched "free_alien_cache()" on an alien pointer that had never been allocated. It might not matter from a code generation standpoint (since in the non-NUMA case, the code doesn't actually _do_ anything), but it not only results in a compiler warning, it's really really ugly too. Fix the compiler warning by just having a matching dummy allocation. That also avoids an unnecessary #ifdef in the code. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * | [NETFILTER]: Fix possible overflow in netfilters do_replace()Kirill Korotaev2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | netfilter's do_replace() can overflow on addition within SMP_ALIGN() and/or on multiplication by NR_CPUS, resulting in a buffer overflow on the copy_from_user(). In practice, the overflow on addition is triggerable on all systems, whereas the multiplication one might require much physical memory to be present due to the check above. Either is sufficient to overwrite arbitrary amounts of kernel memory. I really hate adding the same check to all 4 versions of do_replace(), but the code is duplicate...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Performance tests showed that ULOG may fail on heavy loaded systems because of failed order-N allocations (N >= 1). The default value of 4096 is not optimal in the sense that it actually allocates _two_ contigous physical pages. Reasoning: ULOG uses alloc_skb(), which adds another ~300 bytes for skb_shared_info.

* | [PATCH] VFS: Ensure LOOKUP_CONTINUE flag is preserved by link_path_walk()Trond Myklebust2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When walking a path, the LOOKUP_CONTINUE flag is used by some filesystems (for instance NFS) in order to determine whether or not it is looking up the last component of the path. It this is the case, it may have to look at the intent information in order to perform various tasks such as atomic open. A problem currently occurs when link_path_walk() hits a symlink. In this case LOOKUP_CONTINUE may be cleared prematurely when we hit the end of the path passed by __vfs_follow_link() (i.e. the end of the symlink path) rather than when we hit the end of the path passed by the user. The solution is to have link_path_walk() clear LOOKUP_CONTINUE if and only if that flag was unset when we entered the function.

* | [PATCH] NUMA slab locking fixes: fix cpu down and up lockingRavikiran G Thirumalai2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes locking and bugs in cpu_down and cpu_up paths of the NUMA slab allocator. Sonny Rao <sonny@burdell.org> reported problems sometime back on POWER5 boxes, when the last cpu on the nodes were being offlined. We could not reproduce the same on x86_64 because the cpumask (node_to_cpumask) was not being updated on cpu down. Since that issue is now fixed, we can reproduce Sonny's problems on x86_64 NUMA, and here is the fix. The problem earlier was on CPU_DOWN, if it was the last cpu on the node to go down, the array_caches (shared, alien) and the kmem_list3 of the node were being freed (kfree) with the kmem_list3 lock held. If the l3 or the array_caches were to come from the same cache being cleared, we hit on badness. This patch cleans up the locking in cpu_up and cpu_down path. We cannot really free l3 on cpu down because, there is no node offlining yet and even though a cpu is not yet up, node local memory can be allocated for it. So l3s are usually allocated at keme_cache_create and destroyed at kmem_cache_destroy. Hence, we don't need cachep->spinlock protection to get to the cachep->nodelist[nodeid] either. Patch survived onlining and offlining on a 4 core 2 node Tyan box with a 4 dbench process running all the time.

* | [PATCH] NUMA slab locking fixes: irq disabling from cahep->spinlock to l3 lockRavikiran G Thirumalai2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, we had to disable on chip interrupts while taking the cachep->spinlock because, at cache_grow, on every addition of a slab to a slab cache, we incremented colour_next which was protected by the cachep->spinlock, and cache_grow could occur at interrupt context. Since, now we protect the per-node colour_next with the node's list_lock, we do not need to disable on chip interrupts while taking the per-cache spinlock, but we just need to disable interrupts when taking the per-node kmem_list3 list_lock.

* | [PATCH] NUMA slab locking fixes: move color_next to l3Ravikiran G Thirumalai2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | colour_next is used as an index to add a colouring offset to a new slab in the cache (colour_off * colour_next). Now with the NUMA aware slab allocator, it makes sense to colour slabs added on the same node sequentially with colour_next. This patch moves the colouring index "colour_next" per-node by placing it on kmem_list3 rather than kmem_cache. This also helps simplify locking for CPU up and down paths.

* | [PATCH] jbd: fix transaction batchingAndrew Morton2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ben points out that: When writing files out using O_SYNC, jbd's 1 jiffy delay results in a significant drop in throughput as the disk sits idle. The patch below results in a 4-5x performance improvement (from 6.5MB/s to ~24-30MB/s on my IDE test box) when writing out files using O_SYNC. So optimise the batching code by omitting it entirely if the process which is doing a sync write is the same as the one which did the most recent sync write. If that's true, we're unlikely to get any other processes joining the transaction. (Has been in -mm for ages - it took me a long time to get on to performance testing it) Numbers, on write-cache-disabled IDE: /usr/bin/time -p synctest -n 10 -uf -t 1 -p 1 dir-name Unpatched: 40 seconds Patched: 35 seconds Batching disabled: 35 seconds This is the problematic single-process-doing-fsync case. With multiple fsyncing processes the numbers are AFACIT unaltered by the patch. Aside: performance testing and instrumentation shows that the transaction batching almost doesn't help (testing with synctest -n 1 -uf -t 100 -p 10 dir-name on non-writeback-caching IDE). This is because by the time one process is running a synchronous commit, a bunch of other processes already have a transaction handle open, so they're all going to batch into the same transaction anyway. The batching seems to offer maybe 5-10% speedup with this workload, but I'm pretty sure it was more important than that when it was first developed 4-odd years ago... Cc: "Stephen C.

* | [PATCH] pktcdvd: Fix overflow for discs with large packetsPhillip Susi2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pktcdvd driver was using an 8 bit field to store the packet length obtained from the disc track info. This causes it to overflow packet length values of 128KB or more. I changed the field to 32 bits to fix this. The pktcdvd driver defaulted to its maximum allowed packet length when it detected a 0 in the track info field. I changed this to fail the operation and refuse to access the media. This seems more sane than attempting to access it with a value that almost certainly will not work.

| | | | | | | | | | | | | | | | | | | | | | | | The last fix for this function in fact opened up a much more often triggering race. It was uncommented tricky code, that was buggy.

* | [PATCH] Fix i2o_scsi oops on abortMarkus Lidel2006-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix http://bugzilla.kernel.org/show_bug.cgi?id=5923 When a scsi command failed, an oops would result. Back-to-back SMART queries would make the Seagate drives unhappy. The second SMART query would timeout, and the command would be aborted.
