2007-08-09nfsd: fix possible oops on re-insertion of rpcsec_gss modulesJ. Bruce Fields
The handling of the re-registration case is wrong here; the "test" that was returned from auth_domain_lookup will not be used again, so that reference should be put. And auth_domain_lookup never did anything with "new" in this case, so we should just clean it up ourself. Thanks to Akinobu Mita for bug report, analysis, and testing.

2007-08-09ieee1394: revert "sbp2: enforce 32bit DMA mapping"Stefan Richter
Revert commit 0555659d63c285ceb7ead3115532e1b71b0f27a7 from 2.6.22-rc1. The dma_set_mask call somehow failed on a PowerMac G5, PPC64: http://lkml.org/lkml/2007/8/1/344 Should there ever occur a DMA mapping beyond the physical DMA range, a proper SBP-2 firmware will report transport errors.

2007-08-09cfq-iosched: fix async queue behaviourJens Axboe
With the cfq_queue hash removal, we inadvertently got rid of the async queue sharing. This was not intentional, in fact CFQ purposely shares the async queue per priority level to get good merging for async writes. So put some logic in cfq_get_queue() to track the shared queues.

2007-08-09destroy_workqueue() can livelockOleg Nesterov
Pointed out by Michal Schmidt <mschmidt@redhat.com>. The bug was introduced in 2.6.22 by me. cleanup_workqueue_thread() does flush_cpu_workqueue(cwq) in a loop until ->worklist becomes empty. This is live-lockable, a re-niced caller can get CPU after wake_up() and insert a new barrier before the lower-priority cwq->thread has a chance to clear ->current_work. Change cleanup_workqueue_thread() to do flush_cpu_workqueue(cwq) only once. We can rely on the fact that run_workqueue() won't return until it flushes all works. So it is safe to call kthread_stop() after that, the "should stop" request won't be noticed until run_workqueue() returns.

2007-08-09nfsd: fix possible read-ahead cache and export table corruptionJ. Bruce Fields
The value of nperbucket calculated here is too small--we should be rounding up instead of down--with the result that the index j in the following loop can overflow the raparm_hash array. At least in my case, the next thing in memory turns out to be export_table, so the symptoms I see are crashes caused by the appearance of four zeroed-out export entries in the first bucket of the hash table of exports (which were actually entries in the readahead cache, a pointer to which had been written to the export table in this initialization code). It looks like the bug was probably introduced with commit fce1456a19f5c08b688c29f00ef90fdfa074c79b ("knfsd: make the readahead params cache SMP-friendly").

When user locks an ipc shmem segmant with SHM_LOCK ctl and the segment is already locked the shmem_lock() function returns 0.

The exploit looks like this: == id = shmget(...); setresuid(uid, 0, 0); shmctl(id, SHM_LOCK, NULL); setresuid(uid + 1, 0, 0); shmctl(id, SHM_LOCK, NULL); == My solution is to return 0 to the userspace and do not change the segment's user.

However, that bit was set at the wrong time and could be cleared by mistake if a PCM (or other) DMA request would arrive before the VBI DMA was completed. So on completion of the VBI DMA the driver no longer knew that that DMA transfer was for VBI data. And this in turn caused havoc with the card's DMA engine.

2007-08-09make timerfd return a u64 and fix the __put_userDavide Libenzi
Davi fixed a missing cast in the __put_user(), that was making timerfd return a single byte instead of the full value. Talking with Michael about the timerfd man page, we think it'd be better to use a u64 for the returned value, to align it with the eventfd implementation. This is an ABI change. The timerfd code is new in 2.6.22 and if we merge this into 2.6.23 then we should also merge it into 2.6.22.x. That will leave a few early 2.6.22 kernels out in the wild which might misbehave when a future timerfd-enabled glibc is run on them. mtk says: The difference would be that read() will only return 4 bytes, while the application will expect 8. If the application is checking the size of returned value, as it should, then it will be able to detect the problem (it could even be sophisticated enough to know that if this is a 4-byte return, then it is running on an old 2.6.22 kernel). If the application is not checking the return from read(), then its 8-byte buffer will not be filled -- the contents of the last 4 bytes will be undefined, so the u64 value as a whole will be junk. When I wrote up that description above, I forgot a crucial detail. The above description described the difference between the new behavior implemented by the patch, and the current (i.e., 2.6.22) *intended* behavior. However, as I originally remarked to Davide, the 2.6.22 read() behavior is broken: it should return 4 bytes on a read(), but as originally implemented, only the least significant byte contained valid information. (In other words, the top 3 bytes of overrun information were simply being discarded.) So the patch both fixes a bug in the originally intended behavior, and changes the intended behavior (to return 8 bytes from a read() instead of 4).

2007-08-09firewire: fw-sbp2: set correct maximum payload (fixes CardBus adapters)Stefan Richter
As far as I know, all CardBus FireWire 400 adapters have a maximum payload of 1024 bytes which is less than the speed-dependent limit of 2048 bytes. Fw-sbp2 has to take the host adapter's limit into account. This apparently fixes Juju's incompatibility with my CardBus cards, a NEC based card and a VIA based card.

On the SCSI layer ioctl path there is no implicit permissions check for ioctls (and indeed other drivers implement unprivileged ioctls). aacraid however allows all sorts of very admin only things to be done so should check.

2007-08-09Fix reported task file values in sense dataPetr Vandrovec
ata_tf_read was setting HOB bit when lba48 command was submitted, but was not clearing it before reading "normal" data. As it is only place which sets HOB bit in control register, and register reads should not be affected by other bits, let's just clear it when we are done with reading upper bytes so non-48bit commands do not have to touch ctl at all. pata_scc suffered from same problem...

2007-08-09USB: fix warning caused by autosuspend counter going negativeAlan Stern
This patch (as937) fixes a minor bug in the autosuspend usage-counting code. Each hub's usage counter keeps track of the number of unsuspended children. However the current driver increments the counter after registering a new child, by which time the child may already have been suspended and caused the counter to go negative. The obvious solution is to increment the counter before registering the child. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
