2008-09-02wireless/libertas/if_cs.c: fix memory leaksAdrian Bunk
The leak in if_cs_prog_helper() is obvious. It looks a bit as if not freeing "fw" in if_cs_prog_real() was done intentionally, but I'm not seeing why it shouldn't be freed.

2008-09-02orinoco: Multicast to the specified addressesDavid Kilroy
When multicasting the driver sets the number of group addresses using the count from the previous set multicast command. In general this means you have to set the multicast addresses twice to get the behaviour you want. If we were multicasting, and reduce the number of addresses we are multicasting to, then the driver would write uninitialised data from the stack into the group addresses to multicast to. Only write the multicast addresses we have specifically set. Signed-off-by: David Kilroy <kilroyd@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-09-02Un-break printk strings in x86 PCI probing codeLinus Torvalds
Breaking lines due to some imaginary problem with a long line length is often stupid and wrong, but never more so when it splits a string that is printed out into multiple lines. This really ended up making it much harder to find where some error strings were printed out, because a simple 'grep' didn't work. I'm sure there is tons more of this particular idiocy hiding in other places, but this particular case hit me once more last week. So fix it.

2008-09-02[MTD] mtdchar.c: Fix regression in MEMGETREGIONINFO ioctl()Zev Weiss
The MEMGETREGIONINFO ioctl() in mtdchar.c was clobbering user memory by overwriting more than intended, due the size of struct mtd_erase_region_info changing in commit 0ecbc81adfcb9f15f86b05ff576b342ce81bbef8 ('Support for auto locking flash on power up').

David Wagner added (among other things) that copy_to_user could be probably used here. Ingo Oeser suggested to use simple_read_from_buffer() here. The conclusion is that proc_do_xprt doesn't check for userside buffer size indeed so fix this by using Ingo's suggestion.

2008-09-01avr32: Fix lockup after Java stack underflow in user modeHaavard Skinnemoen
When using the Java Extension Module hardware, a Java stack underflow or overflow trap may cause the system to enter an infinite exception loop. Although there's no kernel support for the Java hardware yet, we need to be able to recover from this situation and keep the system running. This patch adds code to detect and fixup this situation in the critical exception handler and terminate the faulting process. We may have to rethink how to handle this more gracefully when the necessary kernel support for hardware-accelerated Java is added.

2008-09-01Fix problem with waiting while holding rcu read lock in md/bitmap.cNeilBrown
A recent patch to protect the rdev list with rcu locking leaves us with a problem because we can sleep on memalloc while holding the rcu lock. The rcu lock is only needed while walking the linked list as uninteresting devices (failed or spares) can be removed at any time. So only take the rcu lock while actually walking the linked list. Take a refcount on the rdev during the time when we drop the lock and do the memalloc to start IO. When we return to the locked code, all the interesting devices on the list will not have moved, so we can simply use list_for_each_continue_rcu to pick up where we left off.

2008-09-01Remove invalidate_partition call from do_md_stop.NeilBrown
When stopping an md array, or just switching to read-only, we currently call invalidate_partition while holding the mddev lock. The main reason for this is probably to ensure all dirty buffers are flushed (invalidate_partition calls fsync_bdev). However if any dirty buffers are found, it will almost certainly cause a deadlock as starting writeout will require an update to the superblock, and performing that updates requires taking the mddev lock - which is already held. This deadlock can be demonstrated by running "reboot -f -n" with a root filesystem on md/raid, and some dirty buffers in memory. All other calls to stop an array should already happen after a flush. The normal sequence is to stop using the array (e.g. umount) which will cause __blkdev_put to call sync_blockdev. Then open the array and issue the STOP_ARRAY ioctl while the buffers are all still clean. So this invalidate_partition is normally a no-op, except for one case where it will cause a deadlock. So remove it. This patch possibly addresses the regression recored in http://bugzilla.kernel.org/show_bug.cgi?id=11460 and http://bugzilla.kernel.org/show_bug.cgi?id=11452 though it isn't yet clear how it ever worked.
