Without this patch, if you try and use a key that has not been configured, for example: % iwconfig eth1 key deadbeef00 [2] without having configured key [1], then the active key will still be [1], but privacy will now be enabled. Transmission of a packet in this situation will result in a kernel oops. Signed-off-by: NJames Ketrenos <jketreno@linux.intel.com>

This introduces a limit parameter to the core bootmem allocator; The new parameter indicates that physical memory allocated by the bootmem allocator should be within the requested limit. We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit, alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit is the only api used for swiotlb. The existing alloc_bootmem_low_pages() api could instead have been changed and made to pass right limit to the core allocator. But that would make the patch more intrusive for 2.6.14, as other arches use alloc_bootmem_low_pages(). We may be done that post 2.6.14 as a cleanup. With this, swiotlb gets memory within 4G for both x86_64 and ia64 arches.

In drivers/acpi/glue.c the address of an integer is cast to the address of an unsigned long.

The PF_NOFREEZE process flag should not be inherited when a thread is forked. This patch (as585) removes the flag from the child. This problem is starting to show up more and more as drivers turn to the kthread API instead of using kernel_thread(). As a result, their kernel threads are now children of the kthread worker instead of modprobe, and they inherit the PF_NOFREEZE flag. This can cause problems during system suspend; the kernel threads are not getting frozen as they ought to be.

The main problem fixes is that in certain situations stopping md arrays may take longer than you expect, or may require multiple attempts. This would only happen when resync/recovery is happening. This patch fixes three vaguely related bugs. 1/ The recent change to use kthreads got the setting of the process name wrong. This fixes it. 2/ The recent change to use kthreads lost the ability for md threads to be signalled with SIG_KILL. This restores that. 3/ There is a long standing bug in that if: - An array needs recovery (onto a hot-spare) and - The recovery is being blocked because some other array being recovered shares a physical device and - The recovery thread is killed with SIG_KILL Then the recovery will appear to have completed with no IO being done, which can cause data corruption. This patch makes sure that incomplete recovery will be treated as incomplete. Note that any kernel affected by bug 2 will not suffer the problem of bug 3, as the signal can never be delivered. Thus the current 2.6.14-rc kernels are not susceptible to data corruption. Note also that if arrays are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't occur. It only happens if a SIGKILL is independently delivered as done by 'init' when shutting down.

Changes all spinlocks that can be held during an irq handler to disable interrupts while the lock is held. Changes spin_[un]lock_irq to use the irqsave/irqrestore variants for robustness and readability. In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're not accessing host_info_list or host_count, and holding this lock while trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in raw1394.c:receive_iso.

hugetlbfs allows truncation of its files (should it?), but hugetlb.c often forgets that: crashes and misaccounting ensue. copy_hugetlb_page_range better grab the src page_table_lock since we don't want to guess what happens if concurrently truncated. unmap_hugepage_range rss accounting must not assume the full range was mapped. follow_hugetlb_page must guard with page_table_lock and be prepared to exit early.

Oleg Nesterov reported an SMP deadlock. If there is a running timer tracking a different process's CPU time clock when the process owning the timer exits, we deadlock on tasklist_lock in posix_cpu_timer_del via exit_itimers. That code was using tasklist_lock to check for a race with __exit_signal being called on the timer-target task and clearing its ->signal. However, there is actually no such race. __exit_signal will have called posix_cpu_timers_exit and posix_cpu_timers_exit_group before it does that. Those will clear those k_itimer's association with the dying task, so posix_cpu_timer_del will return early and never reach the code in question. In addition, posix_cpu_timer_del called from exit_itimers during execve or directly from timer_delete in the process owning the timer can race with an exiting timer-target task to cause a double put on timer-target task struct. Make sure we always access cpu_timers lists with sighand lock held.

The hugetlb pages are currently pre-faulted. At the time of mmap of hugepages, we populate the new PTEs. It is possible that HW has already cached some of the unused PTEs internally. These stale entries never get a chance to be purged in existing control flow. This patch extends the check in page fault code for hugepages. Check if a faulted address falls with in size for the hugetlb file backing it. We return VM_FAULT_MINOR for these cases (assuming that the arch specific page-faulting code purges the stale entry for the archs that need it).

This is a (final?) hack to support the odd DMA allocation requirements of the b44 hardware. The b44 hardware has a 30-bit DMA mask. On x86, anything less than a 32-bit DMA mask forces allocations into the 16MB GFP_DMA range. The memory there is somewhat limited, often resulting in an inability to initialize the b44 driver. This hack uses streaming DMA allocation APIs in order to provide an alternative in case the GFP_DMA allocation fails. It is somewhat ugly, but not much worse than the similar existing hacks to support SKB allocations in the same driver. FWIW, I have received positive feedback on this from several Fedora users.

Get rid of the mdelay call in rhine_disable_linkmon. The function is called from the via-rhine versions of mdio_read and mdio_write. Those functions are indirectly called from rhine_check_media and rhine_tx_timeout, both of which can be called in interrupt context. So, create tx_timeout_task and check_media_task as instances of struct work_struct inside of rhine_private. Then, change rhine_tx_timeout to invoke schedule_work for tx_timeout_task (i.e. rhine_tx_timeout_task), moving the work to process context. Also, change rhine_error (invoked from rhine_interrupt) to invoke schedule_work for check_media_task (i.e. rhine_check_media_task), which simply calls rhine_check media in process context. Finally, add a call to flush_scheduled_work in rhine_close to avoid any resource conflicts with pending work items. Signed-off-by: NJohn W.
