29c7cf9 Sridhar Samudrala14 December 2006, 00:26:26 UTC[SCTP]: Handle address add/delete events in a more efficient way. Currently in SCTP, we maintain a local address list by rebuilding the whole list from the device list whenever we get a address add/delete event. This patch fixes it by only adding/deleting the address for which we receive the event. Also removed the sctp_local_addr_lock() which is no longer needed as we now use list_for_each_safe() to traverse this list. This fixes the bugs in sctp_copy_laddrs_xxx() routines where we do copy_to_user() while holding this lock. Signed-off-by: Sridhar Samudrala <sri@us.ibm.com> Signed-off-by: David S.

29a7f3a Mathieu Desnoyers24 November 2006, 18:51:14 UTCDebugFS : file/directory removal fix Fix file and directory removal in debugfs. Add inotify support for file removal. The following scenario : create dir a create dir a/b cd a/b (some process goes in cwd a/b) rmdir a/b rmdir a fails due to the fact that "a" appears to be non empty. It is because the "b" dentry is not deleted from "a" and still in use. The same problem happens if "b" is a file. d_delete is nice enough to know when it needs to unhash and free the dentry if nothing else is using it or, if someone is using it, to remove it from the hash queues and wait for it to be deleted when it has no users. The nice side-effect of this fix is that it calls the file removal notification.

65c3333 Mathieu Desnoyers24 November 2006, 18:50:09 UTCDebugFS : more file/directory creation error handling Correct dentry count to handle creation errors. This patch puts a dput at the file creation instead of the file removal : lookup_one_len already returns a dentry with reference count of 1. Then, the dget() in simple_mknod increments it when the dentry is associated with a file. In a scenario where simple_create or simple_mkdir returns an error, this would lead to an unwanted increment of the reference counter, therefore making file removal impossible.

0282884 Nicolas Pitre13 December 2006, 17:39:26 UTC[ARM] 4016/1: prefetch macro is wrong wrt gcc's "delete-null-pointer-checks" optimization The gcc manual says: |`-fdelete-null-pointer-checks' | Use global dataflow analysis to identify and eliminate useless | checks for null pointers. The compiler assumes that dereferencing | a null pointer would have halted the program. If a pointer is | checked after it has already been dereferenced, it cannot be null. | Enabled at levels `-O2', `-O3', `-Os'. Now the problem can be seen with this test case: #include <linux/prefetch.h> extern void bar(char *x); void foo(char *x) { prefetch(x); if (x) bar(x); } Because the constraint to the inline asm used in the prefetch() macro is a memory operand, gcc assumes that the asm code does dereference the pointer and the delete-null-pointer-checks optimization kicks in. Inspection of generated assembly for the above example shows that bar() is indeed called unconditionally without any test on the value of x. Of course in the prefetch case there is no real dereference and it cannot be assumed that a null pointer would have been caught at that point. This causes kernel oopses with constructs like hlist_for_each_entry() where the list's 'next' content is prefetched before the pointer is tested against NULL, and only when gcc feels like applying this optimization which doesn't happen all the time with more complex code. It appears that the way to prevent delete-null-pointer-checks optimization to occur in this case is to make prefetch() into a static inline function instead of a macro. At least this is what is done on x86_64 where a similar inline asm memory operand is used (I presume they would have seen the same problem if it didn't work) and resulting code for the above example confirms that. An alternative would consist of replacing the memory operand by a register operand containing the pointer, and use the addressing mode explicitly in the asm template. But that would be less optimal than an offsettable memory reference.

77fff4a Atsushi Nemoto12 December 2006, 17:14:54 UTC[PATCH] Fix COW D-cache aliasing on fork Problem: 1. There is a process containing two thread (T1 and T2). The thread T1 calls fork(). Then dup_mmap() function called on T1 context. static inline int dup_mmap(struct mm_struct *mm, struct mm_struct *oldmm) ... flush_cache_mm(current->mm); ... /* A */ (write-protect all Copy-On-Write pages) ... /* B */ flush_tlb_mm(current->mm); ... 2. When preemption happens between A and B (or on SMP kernel), the thread T2 can run and modify data on COW pages without page fault (modified data will stay in cache). 3. Some time after fork() completed, the thread T2 may cause a page fault by write-protect on a COW page. 4. Then data of the COW page will be copied to newly allocated physical page (copy_cow_page()). It reads data via kernel mapping. The kernel mapping can have different 'color' with user space mapping of the thread T2 (dcache aliasing). Therefore copy_cow_page() will copy stale data. Then the modified data in cache will be lost. In order to allow architecture code to deal with this problem allow architecture code to override copy_user_highpage() by defining __HAVE_ARCH_COPY_USER_HIGHPAGE in <asm/page.h>.

(Actually, HPT370/A 33 MHz tables also have issues. e.g. HPT370 has PIO modes 0/1 overlocked.) There's also no need in the separate HPT374 tables because HPT372 timings should be the same (and those tables has UltraDMA mode 6 which HPT374 supports depending on HPT374_ALLOW_ATA133_6 #define)...

836c006 Sergei Shtylyov13 December 2006, 08:35:47 UTC[PATCH] ide: HPT3xxN clocking fixes Fix serious problems with the HPT372N clock turnaround code: - the wrong ports were written to when called for the secondary channel; - it didn't serialize access to the channels; - turnaround shou;dn't be done on 66 MHz PCI; - caching the clock mode per-channel caused it to get out of sync with the actual register value. Additionally, avoid calibrating PLL twice (for each channel) as the second try results in a wrong PCI frequency and thus in the wrong timings. Make the driver deal with HPT302N and HPT371N correctly -- the clocking and (seemingly) a need for clock tunaround is the same as for HPT372N. HPT371/N chips have only one, secondary channel, so avoid touching their "pure virtual" primary channel, and disable it if the BIOS haven't done this already. Also, while at it, disable UltraATA/133 for HPT372 by default -- 50 MHz DPLL clock don't allow for this speed anyway. And remove the traces of the former bad patch that wasn't even applicable to this version of driver. Has been tested on HPT370/371N, unfortunately I don't have an instant access to the other chips...

cd7175e Eric Dumazet13 December 2006, 08:35:45 UTC[PATCH] Optimize calc_load() calc_load() is called by timer interrupt to update avenrun[]. It currently calls nr_active() at each timer tick (HZ per second), while the update of avenrun[] is done only once every 5 seconds. (LOAD_FREQ=5 Hz) nr_active() is quite expensive on SMP machines, since it has to sum up nr_running and nr_uninterruptible of all online CPUS, bringing foreign dirty cache lines. This patch is an optimization of calc_load() so that nr_active() is called only if we need it. The use of unlikely() is welcome since the condition is true only once every 5*HZ time.

Certain failures during the deferral process can cause us to really drop the request and never revisit it. This is often less than ideal, and is unacceptable in the NFSv4 case--rfc 3530 forbids the server from dropping a request without also closing the connection. As a first step, we modify the deferral code to return -ETIMEDOUT (which is translated to nfserr_jukebox in the v3 and v4 cases, and remains a drop in the v2 case). Signed-off-by: J.

Also, update a few of the RTC drivers to stop providing that duplicate status, and/or to expose it properly when reporting the alarm state. We really don't want every RTC driver doing their own thing here...

90aef12 Jeremy Fitzhardinge13 December 2006, 08:34:49 UTC[PATCH] Use activate_mm() in fs/aio.c:use_mm() activate_mm() is not the right thing to be using in use_mm(). It should be switch_mm(). On normal x86, they're synonymous, but for the Xen patches I'm adding a hook which assumes that activate_mm is only used the first time a new mm is used after creation (I have another hook for dealing with dup_mm). I think this use of activate_mm() is the only place where it could be used a second time on an mm. >From a quick look at the other architectures I think this is OK (most simply implement one in terms of the other), but some are doing some subtly different stuff between the two.

74c383f Ingo Molnar13 December 2006, 08:34:43 UTC[PATCH] lockdep: fix possible races while disabling lock-debugging Jarek Poplawski noticed that lockdep global state could be accessed in a racy way if one CPU did a lockdep assert (shutting lockdep down), while the other CPU would try to do something that changes its global state. This patch fixes those races and cleans up lockdep's internal locking by adding a graph_lock()/graph_unlock()/debug_locks_off_graph_unlock helpers. (Also note that as we all know the Linux kernel is, by definition, bug-free and perfect, so this code never triggers, so these fixes are highly theoretical. I wrote this patch for aesthetic reasons alone.)

e61c901 Chen, Kenneth W13 December 2006, 08:34:36 UTC[PATCH] optimize o_direct on block devices Implement block device specific .direct_IO method instead of going through generic direct_io_worker for block device. direct_io_worker() is fairly complex because it needs to handle O_DIRECT on file system, where it needs to perform block allocation, hole detection, extents file on write, and tons of other corner cases. The end result is that it takes tons of CPU time to submit an I/O. For block device, the block allocation is much simpler and a tight triple loop can be written to iterate each iovec and each page within the iovec in order to construct/prepare bio structure and then subsequently submit it to the block layer. This significantly speeds up O_D on block device.
