9c95e73 | Hiroshi Shimamoto | 19 September 2007, 21:34:46 UTC | sched: fix invalid sched_class use When using rt_mutex, a NULL pointer dereference is occurred at enqueue_task_rt. Here is a scenario; 1) there are two threads, the thread A is fair_sched_class and thread B is rt_sched_class. 2) Thread A is boosted up to rt_sched_class, because the thread A has a rt_mutex lock and the thread B is waiting the lock. 3) At this time, when thread A create a new thread C, the thread C has a rt_sched_class. 4) When doing wake_up_new_task() for the thread C, the priority of the thread C is out of the RT priority range, because the normal priority of thread A is not the RT priority. It makes data corruption by overflowing the rt_prio_array. The new thread C should be fair_sched_class. The new thread should be valid scheduler class before queuing. This patch fixes to set the suitable scheduler class.

dbe3ed1 | Linus Torvalds | 19 September 2007, 18:37:14 UTC | x86-64: page faults from user mode are always user faults Randy Dunlap noticed an interesting "crashme" behaviour on his dual Prescott Xeon setup, where he gets page faults with the error code having a zero "user" bit, but the register state points back to user mode. This may be a CPU microcode buglet triggered by some strange instruction pattern that crashme generates, and loading a microcode update seems to possibly have fixed it. Regardless, we really should trust the register state more than the error code, since it's really the register state that determines whether we can actually send a signal, or whether we're in kernel mode and need to oops/kill the process in the case of a page fault.

508a927 | Jeff Dike | 19 September 2007, 05:46:49 UTC | uml: fix irqstack crash This patch fixes a crash caused by an interrupt coming in when an IRQ stack is being torn down. When this happens, handle_signal will loop, setting up the IRQ stack again because the tearing down had finished, and handling whatever signals had come in. However, to_irq_stack returns a mask of pending signals to be handled, plus bit zero is set if the IRQ stack was already active, and thus shouldn't be torn down. This causes a problem because when handle_signal goes around the loop, sig will be zero, and to_irq_stack will duly set bit zero in the returned mask, faking handle_signal into believing that it shouldn't tear down the IRQ stack and return thread_info pointers back to their original values. This will eventually cause a crash, as the IRQ stack thread_info will continue pointing to the original task_struct and an interrupt will look into it after it has been freed. The fix is to stop passing a signal number into to_irq_stack. Rather, the pending signals mask is initialized beforehand with the bit for sig already set. References to sig in to_irq_stack can be replaced with references to the mask.

480eccf | Lee Schermerhorn | 19 September 2007, 05:46:47 UTC | Fix NUMA Memory Policy Reference Counting This patch proposes fixes to the reference counting of memory policy in the page allocation paths and in show_numa_map(). Extracted from my "Memory Policy Cleanups and Enhancements" series as stand-alone. Shared policy lookup [shmem] has always added a reference to the policy, but this was never unrefed after page allocation or after formatting the numa map data. Default system policy should not require additional ref counting, nor should the current task's task policy. However, show_numa_map() calls get_vma_policy() to examine what may be [likely is] another task's policy. The latter case needs protection against freeing of the policy. This patch adds a reference count to a mempolicy returned by get_vma_policy() when the policy is a vma policy or another task's mempolicy. Again, shared policy is already reference counted on lookup. A matching "unref" [__mpol_free()] is performed in alloc_page_vma() for shared and vma policies, and in show_numa_map() for shared and another task's mempolicy. We can call __mpol_free() directly, saving an admittedly inexpensive inline NULL test, because we know we have a non-NULL policy. Handling policy ref counts for hugepages is a bit trickier. huge_zonelist() returns a zone list that might come from a shared or vma 'BIND policy. In this case, we should hold the reference until after the huge page allocation in dequeue_hugepage(). The patch modifies huge_zonelist() to return a pointer to the mempolicy if it needs to be unref'd after allocation.

28f300d | Pavel Emelyanov | 19 September 2007, 05:46:45 UTC | Fix user namespace exiting OOPs It turned out, that the user namespace is released during the do_exit() in exit_task_namespaces(), but the struct user_struct is released only during the put_task_struct(), i.e. MUCH later. On debug kernels with poisoned slabs this will cause the oops in uid_hash_remove() because the head of the chain, which resides inside the struct user_namespace, will be already freed and poisoned. Since the uid hash itself is required only when someone can search it, i.e. when the namespace is alive, we can safely unhash all the user_struct-s from it during the namespace exiting. The subsequent free_uid() will complete the user_struct destruction. For example simple program #include <sched.h> char stack[2 * 1024 * 1024]; int f(void *foo) { return 0; } int main(void) { clone(f, stack + 1 * 1024 * 1024, 0x10000000, 0); return 0; } run on kernel with CONFIG_USER_NS turned on will oops the kernel immediately.

ef2b02d | Eric Sandeen | 19 September 2007, 05:46:42 UTC | ext34: ensure do_split leaves enough free space in both blocks The do_split() function for htree dir blocks is intended to split a leaf block to make room for a new entry. It sorts the entries in the original block by hash value, then moves the last half of the entries to the new block - without accounting for how much space this actually moves. (IOW, it moves half of the entry *count* not half of the entry *space*). If by chance we have both large & small entries, and we move only the smallest entries, and we have a large new entry to insert, we may not have created enough space for it. The patch below stores each record size when calculating the dx_map, and then walks the hash-sorted dx_map, calculating how many entries must be moved to more evenly split the existing entries between the old block and the new block, guaranteeing enough space for the new entry. The dx_map "offs" member is reduced to u16 so that the overall map size does not change - it is temporarily stored at the end of the new block, and if it grows too large it may be overwritten. By making offs and size both u16, we won't grow the map size. Also add a few comments to the functions involved. This fixes the testcase reported by hooanon05@yahoo.co.jp on the linux-ext4 list, "ext3 dir_index causes an error" Thanks to Andreas Dilger for discussing the problem & solution with me.

4191ba2 | Cliff Wickman | 19 September 2007, 05:46:31 UTC | mspec: handle shrinking virtual memory areas The shrinking of a virtual memory area that is mmap(2)'d to a memory special file (device drivers/char/mspec.c) can cause a panic. If the mapped size of the vma (vm_area_struct) is very large, mspec allocates a large vma_data structure with vmalloc(). But such a vma can be shrunk by an munmap(2). The current driver uses the current size of each vma to deduce whether its vma_data structure was allocated by kmalloc() or vmalloc(). So if the vma was shrunk it appears to have been allocated by kmalloc(), and mspec attempts to free it with kfree(). This results in a panic. This patch avoids the panic (by preserving the type of the allocation) and also makes mspec work correctly as the vma is split into pieces by the munmap(2)'s. All vma's derived from such a split vma share the same vma_data structure that represents all the pages mapped into this set of vma's. The mpec driver must be made capable of using the right portion of the structure for each member vma. In other words, it must index into the array of page addresses using the portion of the array that represents the current vma. This is enabled by storing the vma group's vm_start in the vma_data structure. The shared vma_data's are not protected by mm->mmap_sem in the fork() case so the reference count is left as atomic_t.

CONFIG_THINKPAD_ACPI_INPUT_ENABLED was added to try to fix an issue that is now moot with the addition of the netlink ACPI event report interface to the ACPI core. Now that ACPI core can send events over netlink, we can use a different strategy to keep backwards compatibility with older userspace, without the need for the CONFIG_THINKPAD_ACPI_INPUT_ENABLED games. And it arrived before CONFIG_THINKPAD_ACPI_INPUT_ENABLED made it to a stable mainline kernel, even, which is Good. This patch is in sync with some changes to thinkpad-acpi backports, that will keep things sane for userspace across different combinations of kernel versions, thinkpad-acpi backports (or the lack thereof), and userspace capabilities: Unless a module parameter is used, thinkpad-acpi will now behave in such a way that it will work well (by default) with userspace that still uses only the old ACPI procfs event interface and doesn't care for thinkpad-acpi input devices. It will also always work well with userspace that has been updated to use both the thinkpad-acpi input devices, and ACPI core netlink event interface, regardless of any module parameter. The module parameter was added to allow thinkpad-acpi to work with userspace that has been partially updated to use thinkpad-acpi input devices, but not the new ACPI core netlink event interface. To use this mode of hot key reporting, one has to specify the hotkey_report_mode=2 module parameter. The thinkpad-acpi driver exports the value of hotkey_report_mode through sysfs, as well. thinkpad-acpi backports to older kernels, that do not support the new ACPI core netlink interface, have code to allow userspace to switch hotkey_report_mode at runtime through sysfs. This capability will not be provided in mainline thinkpad-acpi as it is not needed there. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Cc: Michael S.

There are only 2 writers to the list: bind()/bindx() calls, and BH processing of ASCONF-ACK chunks. These are already seriealized via the socket lock, so they will not step on each other. These are also relatively rare, so we should be good with RCU. The readers are varied and they are easily converted to RCU. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Acked-by: Paul E.

301feb6 | David S. Miller | 16 September 2007, 18:51:15 UTC | [SPARC64]: Fix lockdep, particularly on SMP. As noted by Al Viro, when we try to call prom_set_trap_table() in the SMP trampoline code we try to take the PROM call spinlock which doesn't work because the current thread pointer isn't valid yet and lockdep depends upon that being correct. Furthermore, we cannot set the current thread pointer register because it can't be properly dereferenced until we return from prom_set_trap_table(). Kernel TLB misses only work after that call. So do the PROM call to set the trap table directly instead of going through the OBP library C code, and thus avoid the lock altogether. These calls are guarenteed to be serialized fully. Since there are now no calls to the prom_set_trap_table{_sun4v}() library functions, they can be deleted. Signed-off-by: David S. Miller <davem@davemloft.net> | 16 September 2007, 18:51:15 UTC |

5e41d0d | Thomas Gleixner | 16 September 2007, 13:36:43 UTC | clockevents: prevent stale tick update on offline cpu Taking a cpu offline removes the cpu from the online mask before the CPU_DEAD notification is done. The clock events layer does the cleanup of the dead CPU from the CPU_DEAD notifier chain. tick_do_timer_cpu is used to avoid xtime lock contention by assigning the task of jiffies xtime updates to one CPU. If a CPU is taken offline, then this assignment becomes stale. This went unnoticed because most of the time the offline CPU went dead before the online CPU reached __cpu_die(), where the CPU_DEAD state is checked. In the case that the offline CPU did not reach the DEAD state before we reach __cpu_die(), the code in there goes to sleep for 100ms. Due to the stale time update assignment, the system is stuck forever. Take the assignment away when a cpu is not longer in the cpu_online_mask. We do this in the last call to tick_nohz_stop_sched_tick() when the offline CPU is on the way to the final play_dead() idle entry.

6a669ee | Thomas Gleixner | 16 September 2007, 13:36:43 UTC | timekeeping: Prevent time going backwards on resume Timekeeping resume adjusts xtime by adding the slept time in seconds and resets the reference value of the clock source (clock->cycle_last). clock->cycle last is used to calculate the delta between the last xtime update and the readout of the clock source in __get_nsec_offset(). xtime plus the offset is the current time. The resume code ignores the delta which had already elapsed between the last xtime update and the actual time of suspend. If the suspend time is short, then we can see time going backwards on resume. Suspend: offs_s = clock->read() - clock->cycle_last; now = xtime + offs_s; timekeeping_suspend_time = read_rtc(); Resume: sleep_time = read_rtc() - timekeeping_suspend_time; xtime.tv_sec += sleep_time; clock->cycle_last = clock->read(); offs_r = clock->read() - clock->cycle_last; now = xtime + offs_r; if sleep_time_seconds == 0 and offs_r < offs_s, then time goes backwards. Fix this by storing the offset from the last xtime update and add it to xtime during resume, when we reset clock->cycle_last: sleep_time = read_rtc() - timekeeping_suspend_time; xtime.tv_sec += sleep_time; xtime += offs_s; /* Fixup xtime offset at suspend time */ clock->cycle_last = clock->read(); offs_r = clock->read() - clock->cycle_last; now = xtime + offs_r; Thanks to Marcelo for tracking this down on the OLPC and providing the necessary details to analyze the root cause.

4878809 | David S. Miller | 14 September 2007, 23:41:03 UTC | [NET]: Fix two issues wrt. SO_BINDTODEVICE. 1) Comments suggest that setting optlen to zero will unbind the socket from whatever device it might be attached to. This hasn't been the case since at least 2.2.x because the first thing this function does is return -EINVAL if 'optlen' is less than sizeof(int). This check also means that passing in a two byte string doesn't work so well. It's almost as if this code was testing with "eth?" patterned strings and nothing else :-) Fix this by breaking the logic of this facility out into a seperate function which validates optlen more appropriately. The optlen==0 and small string cases now work properly. 2) We should reset the cached route of the socket after we have made the device binding changes, not before. Reported by Ben Greear.

This fix modifies the shutdown of work queues and prevents periodic work from being requeued during shutdown. With this patch, no more crashes on reboot were observed by the original reporter. I do not get that particular failure on my system; however, when running a large number of ifdown/ifup sequences, my system would kernel panic with the 'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT' errors. With this patch, no more of the first type of failure occur, and incidence of the second type is greatly reduced.
