2013-02-08drm/ttm: fix fence locking in ttm_buffer_object_transfer, 2nd tryDaniel Vetter1-5/+8
This fixes up commit e8e89622ed361c46bf90ba4828e685a8b603f7e5 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Dec 18 22:25:11 2012 +0100 drm/ttm: fix fence locking in ttm_buffer_object_transfer which leaves behind a might_sleep in atomic context, since the fence_lock spinlock is held over a kmalloc(GFP_KERNEL) call. The fix is to revert the above commit and only take the lock where we need it, around the call to ->sync_obj_ref. v2: Fixup things noticed by Maarten Lankhorst: - Brown paper bag locking bug. - No need for kzalloc if we clear the entire thing on the next line. - check for bo->sync_obj (totally unlikely race, but still someone else could have snuck in) and clear fbo->sync_obj if it's cleared already.

2013-02-07ALSA: hda - Remove limit of widget connectionsTakashi Iwai4-28/+61
Currently we set the max number of connections to be 32, but there seems codec that gives longer connection lists like AD1988, and we see errors in proc output and else. (Though, in the case of AD1988, it's a list of all codecs connected to a single vendor widget, so this must be something fishy, but it's still valid from the h/w design POV.) This patch tries to remove this restriction. For efficiency, we still use the fixed size array in the parser, but takes a dynamic array when the size is reported to be greater than that. Now the fixed array size is found only in patch_hdmi.c, but it should be fine, as the codec itself can't support so many pins.

There are transients during normal FRTO procedure during which the packets_in_flight can go to zero between write_queue state updates and firing the resulting segments out. As FRTO processing occurs during that window the check must be more precise to not match "spuriously" :-).

Additionally, the error handling code didn't take into account that we dropped the inode lock which might require more cleanup. Luckily, all the cleanup code we need is already there and can be shared with reserve_metadata_bytes, which is exactly what this patch does.

2013-02-06Btrfs: fix possible stale data exposureJosef Bacik1-1/+1
We specifically do not update the disk i_size if there are ordered extents outstanding for any area between the current disk_i_size and our ordered extent so that we do not expose stale data. The problem is the check we have only checks if the ordered extent starts at or after the current disk_i_size, which doesn't take into account an ordered extent that starts before the current disk_i_size and ends past the disk_i_size. Fix this by checking if the extent ends past the disk_i_size. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

If we have an ordered extent before the ordered extent we are currently completing that is after the current disk_i_size we will put our i_size update into that ordered extent so that we do not expose stale data. The problem is that if our disk i_size is updated past the previous ordered extent we won't update the i_size with the pending i_size update. So check the pending i_size update and if its above the current disk i_size we need to go ahead and try to update. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
2013-02-06Btrfs: fix race between snapshot deletion and getting inodeLiu Bo2-9/+38
While running snapshot testscript created by Mitch and David, the race between autodefrag and snapshot deletion can lead to corruption of dead_root list so that we can get crash on btrfs_clean_old_snapshots(). And besides autodefrag, scrub also does the same thing, ie. read root first and get inode. Here is the story(take autodefrag as an example): (1) when we delete a snapshot or subvolume, it will set its root's refs to zero and do a iput() on its own inode, and if this inode happens to be the only active in-meory one in root's inode rbtree, it will add itself to the global dead_roots list for later cleanup. (2) after (1), the autodefrag thread may read another inode for defrag and the inode is just in the deleted snapshot/subvolume, but all of these are without checking if the root is still valid(refs > 0). So the end up result is adding the deleted snapshot/subvolume's root to the global dead_roots list AGAIN. Fortunately, we already have a srcu lock to avoid the race, ie. subvol_srcu. So all we need to do is to take the lock to protect 'read root and get inode', since we synchronize to wait for the rcu grace period before adding something to the global dead_roots list.

Commit 1fb9fed6d489 ("IB/qib: Fix QP RCU sparse warning") broke QP hash list deletion in qp_remove() badly. This patch restores the former for loop behavior, while still fixing the sparse warnings.

2013-02-05mlx4_core: Fix advertisement of wrong PF context behaviourOr Gerlitz1-1/+1
Commit 08ff32352d6f ("mlx4: 64-byte CQE/EQE support") introduced a regression where older guest VF drivers failed to load even when 64-byte EQEs/CQEs are disabled, since the PF wrongly advertises the new context behaviour anyway. The failure looks like: mlx4_core 0000:00:07.0: Unknown pf context behaviour mlx4_core 0000:00:07.0: Failed to obtain slave caps mlx4_core: probe of 0000:00:07.0 failed with error -38 Fix this by basing this advertisement on dev->caps.flags, which is the operational capabilities used by the QUERY_FUNC_CAP command wrapper (dev_cap->flags holds the firmware capabilities).
