2011-09-16ibmveth: Fix DMA unmap errorBrian King
Commit 6e8ab30ec677 (ibmveth: Add scatter-gather support) introduced a DMA mapping API inconsistency resulting in dma_unmap_page getting called on memory mapped via dma_map_single. This was seen when CONFIG_DMA_API_DEBUG was enabled. Fix up this API usage inconsistency.

2011-09-16tcm_fc: Work queue based approach instead of managing own thread and event ↵Christoph Hellwig
based mechanism Problem: Changed from wake_up_interruptible -> wake_up_process and wait_event_interruptible-> schedule_timeout_interruptible broke the FCoE target. Earlier approach of wake_up_interruptible was also looking at 'queue_cnt' which is not necessary, because it increment of 'queue_cnt' with wake_up_inetrriptible / waker_up_process introduces race condition. Fix: Instead of fixing the code which used wake_up_process and remove 'queue_cnt', using work_queue based approach is cleaner and acheives same result. As well, work queue based approach has less programming overhead and OS manages threads which processes work queues. This patch is developed by Christoph Hellwig and reviwed+validated by Kiran Patil.

2011-09-16tcm_fc: Invalidation of DDP context for FCoE target in error conditionsKiran Patil
Problem: HW DDP context wasn;t invalidated in case of ABORTS, etc... This leads to the problem where memory pages which are used for DDP as user descriptor could get reused for some other purpose (such as to satisfy new memory allocation request either by kernel or user mode threads) and since HW DDP context was not invalidated, HW continue to write to those pages, hence causing memory corruption. Fix: Either on incoming ABORTS or due to exchange time out, allowed the target to cleanup HW DDP context if it was setup for respective ft_cmd. Added new function to perform this cleanup, furthur it can be enhanced for other cleanup activity. Additinal Notes: To avoid calling ddp_done from multiple places, composed the functionality in helper function "ft_invl_hw_context" and it is being called from multiple places. Cleaned up code in function "ft_recv_write_data" w.r.t DDP. Signed-off-by: Kiran Patil <kiran.patil@intel.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2011-09-16target: Fix race between multiple invocations of target_qf_do_work()Roland Dreier
When work is scheduled with schedule_work(), the work can end up running on multiple CPUs at the same time -- this happens if the work is already running on one CPU and schedule_work() is called on another CPU. This leads to list corruption with target_qf_do_work(), which is roughly doing: spin_lock(...); list_for_each_entry_safe(...) { list_del(...); spin_unlock(...); // do stuff spin_lock(...); } With multiple CPUs running this code, one CPU can end up deleting the list entry that the other CPU is about to work on. Fix this by splicing the list entries onto a local list and then operating on that in the work function. This way, each invocation of target_qf_do_work() operates on its own local list and so multiple invocations don't corrupt each other's list. This also avoids dropping and reacquiring the lock for each list entry. Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2011-09-15asm alternatives: remove incorrect alignment notesLinus Torvalds
On x86-64, they were just wasteful: with the explicitly added (now unnecessary) padding, the size of the alternatives structure was 16 bytes, and an alignment of 8 bytes didn't hurt much. However, it was still silly, since the natural size and alignment for the structure is actually just 12 bytes, 4-byte aligned since commit 59e97e4d6fbc ("x86: Make alternative instruction pointers relative"). So removing the padding, and removing the extra alignment is just a good idea. On x86-32, the alignment of 4 bytes was correct, but was incorrectly hardcoded as 8 bytes in <asm/alternative-asm.h>. That header file had used to be an x86-64 only header file, but various unification efforts have made it be used for x86-32 too (ie the unification of rwlock and rwsem). That in turn caused x86-32 boot failures, because the extra alignment would result in random zero-filled words in the altinstructions section, causing oopses early at boot when doing alternative instruction replacement. So just remove all the alignment noise entirely. It's wrong, and it's unnecessary. The section itself is already properly aligned by the linker scripts, and all additions to the section had better be of the proper 12-byte format, keeping it aligned. So if the align directive were to ever make a difference, that would be an indication of a serious bug to begin with.

dev_forward_skb loops an skb back into host networking stack which might hang on the memory indefinitely. In particular, this can happen in macvtap in bridged mode. Copy the userspace fragments to avoid blocking the sender in that case. As this patch makes skb_copy_ubufs extern now, I also added some documentation and made it clear the SKBTX_DEV_ZEROCOPY flag automatically instead of doing it in all callers.

2011-09-15ALSA: pcm - fix race condition in wait_for_avail()Arjan van de Ven
wait_for_avail() in pcm_lib.c has a race in it (observed in practice by an Intel validation group). The function is supposed to return once space in the buffer has become available, or if some timeout happens. The entity that creates space (irq handler of sound driver and some such) will do a wake up on a waitqueue that this function registers for. However there are two races in the existing code 1) If space became available between the caller noticing there was no space and this function actually sleeping, the wakeup is missed and the timeout condition will happen instead 2) If a wakeup happened but not sufficient space became available, the code will loop again and wait for more space. However, if the second wake comes in prior to hitting the schedule_timeout_interruptible(), it will be missed, and potentially you'll wait out until the timeout happens. The fix consists of using more careful setting of the current state (so that if a wakeup happens in the main loop window, the schedule_timeout() falls through) and by checking for available space prior to going into the schedule_timeout() loop, but after being on the waitqueue and having the state set to interruptible.
