2011-09-16rtl2800usb: Fix incorrect storage of MAC address on big-endian platformsLarry Finger1-8/+9
The eeprom data is stored in little-endian order in the rt2x00 library. As it was converted to cpu order in the read routines, the data need to be converted to LE on a big-endian platform.

2011-09-16wireless: Reset beacon_found while updating regulatoryRajkumar Manoharan1-0/+1
During the association, the regulatory is updated by country IE that reaps the previously found beacons. The impact is that after a STA disconnects *or* when for any reason a regulatory domain change happens the beacon hint flag is not cleared therefore preventing future beacon hints to be learned. This is important as a regulatory domain change or a restore of regulatory settings would set back the passive scan and no-ibss flags on the channel. This is the right place to do this given that it covers any regulatory domain change. Cc: [email protected] Reviewed-by: Luis R.

Fix a number of issues in ibmveth_set_csum_offload: - set_attr6 and clr_attr6 may be used uninitialised - We store the result of the IPV4 checksum change in ret but overwrite it in a couple of places before checking it again later.

2011-09-16tcm_fc: Work queue based approach instead of managing own thread and event ↵Christoph Hellwig3-93/+16
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 Patil1-32/+30
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 <[email protected]> Signed-off-by: Nicholas Bellinger <[email protected]>
2011-09-16target: Fix race between multiple invocations of target_qf_do_work()Roland Dreier1-5/+4
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 <[email protected]> Signed-off-by: Nicholas Bellinger <[email protected]>

2011-09-15asm alternatives: remove incorrect alignment notesLinus Torvalds3-7/+0
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.
