2012-02-24mm: memcg: Correct unregistring of events attached to the same eventfdAnton Vorontsov1-1/+4
There is an issue when memcg unregisters events that were attached to the same eventfd: - On the first call mem_cgroup_usage_unregister_event() removes all events attached to a given eventfd, and if there were no events left, thresholds->primary would become NULL; - Since there were several events registered, cgroups core will call mem_cgroup_usage_unregister_event() again, but now kernel will oops, as the function doesn't expect that threshold->primary may be NULL. That's a good question whether mem_cgroup_usage_unregister_event() should actually remove all events in one go, but nowadays it can't do any better as cftype->unregister_event callback doesn't pass any private event-associated cookie. So, let's fix the issue by simply checking for threshold->primary. FWIW, w/o the patch the following oops may be observed: BUG: unable to handle kernel NULL pointer dereference at 0000000000000004 IP: [<ffffffff810be32c>] mem_cgroup_usage_unregister_event+0x9c/0x1f0 Pid: 574, comm: kworker/0:2 Not tainted 3.3.0-rc4+ #9 Bochs Bochs RIP: 0010:[<ffffffff810be32c>] [<ffffffff810be32c>] mem_cgroup_usage_unregister_event+0x9c/0x1f0 RSP: 0018:ffff88001d0b9d60 EFLAGS: 00010246 Process kworker/0:2 (pid: 574, threadinfo ffff88001d0b8000, task ffff88001de91cc0) Call Trace: [<ffffffff8107092b>] cgroup_event_remove+0x2b/0x60 [<ffffffff8103db94>] process_one_work+0x174/0x450 [<ffffffff8103e413>] worker_thread+0x123/0x2d0 Cc: stable <[email protected]> Signed-off-by: Anton Vorontsov <[email protected]> Acked-by: KAMEZAWA Hiroyuki <[email protected]> Cc: Kirill A.

2012-02-24iommu/omap: fix erroneous omap-iommu-debug API callsOhad Ben-Cohen1-12/+43
Adapt omap-iommu-debug to the latest omap-iommu API changes, which were introduced by commit fabdbca "iommu/omap: eliminate the public omap_find_iommu_device() method". In a nutshell, iommu users are not expected to provide the omap_iommu handle anymore - instead, iommus are attached using their user's device handle. omap-iommu-debug is a hybrid beast though: it invokes both public and private omap iommu API, so fix it as necessary (otherwise a crash is imminent). Note: omap-iommu-debug is a bit disturbing, as it fiddles with internal omap iommu data and requires exposing API which is otherwise not needed. It should better be more tightly coupled with omap-iommu, to prevent further bit rot and avoid exposing redundant API. Naturally that's out of scope for the -rc cycle, so for now just fix the obvious.

2012-02-24netfilter: ctnetlink: fix soft lockup when netlink adds new entries (v2)Jozsef Kadlecsik3-35/+51
Marcell Zambo and Janos Farago noticed and reported that when new conntrack entries are added via netlink and the conntrack table gets full, soft lockup happens. This is because the nf_conntrack_lock is held while nf_conntrack_alloc is called, which is in turn wants to lock nf_conntrack_lock while evicting entries from the full table. The patch fixes the soft lockup with limiting the holding of the nf_conntrack_lock to the minimum, where it's absolutely required. It required to extend (and thus change) nf_conntrack_hash_insert so that it makes sure conntrack and ctnetlink do not add the same entry twice to the conntrack table.

2012-02-24LDM: Fix reassembly of extended VBLKs.Anton Altaparmakov1-7/+4
From: Ben Hutchings <[email protected]> Extended VBLKs (those larger than the preset VBLK size) are divided into fragments, each with its own VBLK header. Our LDM implementation generally assumes that each VBLK is contiguous in memory, so these fragments must be assembled before further processing. Currently the reassembly seems to be done quite wrongly - no VBLK header is copied into the contiguous buffer, and the length of the header is subtracted twice from each fragment. Also the total length of the reassembled VBLK is calculated incorrectly. Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: Anton Altaparmakov <[email protected]>

2012-02-24davinci_emac: Do not free all rx dma descriptors during initChristian Riesch1-2/+4
This patch fixes a regression that was introduced by commit 0a5f38467765ee15478db90d81e40c269c8dda20 davinci_emac: Add Carrier Link OK check in Davinci RX Handler Said commit adds a check whether the carrier link is ok. If the link is not ok, the skb is freed and no new dma descriptor added to the rx dma channel. This causes trouble during initialization when the carrier status has not yet been updated. If a lot of packets are received while netif_carrier_ok returns false, all dma descriptors are freed and the rx dma transfer is stopped. The bug occurs when the board is connected to a network with lots of traffic and the ifconfig down/up is done, e.g., when reconfiguring the interface with DHCP. The bug can be reproduced by flood pinging the davinci board while doing ifconfig eth0 down ifconfig eth0 up on the board. After that, the rx path stops working and the overrun value reported by ifconfig is counting up. This patch reverts commit 0a5f38467765ee15478db90d81e40c269c8dda20 and instead issues warnings only if cpdma_chan_submit returns -ENOMEM.

2012-02-23Restore direct_io / truncate locking APIAnton Altaparmakov1-2/+2
With kernel 3.1, Christoph removed i_alloc_sem and replaced it with calls (namely inode_dio_wait() and inode_dio_done()) which are EXPORT_SYMBOL_GPL() thus they cannot be used by non-GPL file systems and further inode_dio_wait() was pushed from notify_change() into the file system ->setattr() method but no non-GPL file system can make this call. That means non-GPL file systems cannot exist any more unless they do not use any VFS functionality related to reading/writing as far as I can tell or at least as long as they want to implement direct i/o. Both Linus and Al (and others) have said on LKML that this breakage of the VFS API should not have happened and that the change was simply missed as it was not documented in the change logs of the patches that did those changes. This patch changes the two function exports in question to be EXPORT_SYMBOL() thus restoring the VFS API as it used to be - accessible for all modules. Christoph, who introduced the two functions and exported them GPL-only is CC-ed on this patch to give him the opportunity to object to the symbols being changed in this manner if he did indeed intend them to be GPL-only and does not want them to become available to all modules.

When setting overlay position with x<0, it will divide 0 and make drm driver crash. Signed-off-by: Hai Lan <[email protected]> Signed-off-by: Jesse Barnes <[email protected]>
2012-02-23drm/i915: fix mode set on load pipe. (v2)Dave Airlie1-1/+1
Booted my i965 machine and it started printing the unsupported pixel format of 0 message (once I added content to it). Oh looksie here, we pass 0. fix. v2: compile it.

2012-02-23Btrfs: increase the global block reserve estimatesLiu Bo1-1/+1
When doing IO with large amounts of data fragmentation, the global block reserve calulations are too low. This increases them to avoid ENOSPC crashes. Signed-off-by: Liu Bo <[email protected]> Signed-off-by: Chris Mason <[email protected]>
2012-02-23Btrfs: clear the extent uptodate bits during parent transid failuresChris Mason1-4/+3
If btrfs reads a block and finds a parent transid mismatch, it clears the uptodate flags on the extent buffer, and the pages inside it. But we only clear the uptodate bits in the state tree if the block straddles more than one page. This is from an old optimization from to reduce contention on the extent state tree. But it is buggy because the code that retries a read from a different copy of the block is going to find the uptodate state bits set and skip the IO. The end result of the bug is that we'll never actually read the good copy (if there is one). The fix here is to always clear the uptodate state bits, which is safe because this code is only called when the parent transid fails. Signed-off-by: Chris Mason <[email protected]>

2012-02-23Btrfs: make sure we update latest_bdevChris Mason2-1/+22
When we are setting up the mount, we close all the devices that were not actually part of the metadata we found. But, we don't make sure that one of those devices wasn't fs_devices->latest_bdev, which means we can do a use after free on the one we closed. This updates latest_bdev as it goes.

2012-02-23Btrfs: improve error handling for btrfs_insert_dir_item callersChris Mason2-7/+26
This allows us to gracefully continue if we aren't able to insert directory items, both for normal files/dirs and snapshots. Signed-off-by: Chris Mason <[email protected]>
2012-02-23ASoC: dapm: Check for bias level when powering downMark Brown1-3/+9
Recent enhancements in the bias management means that we might not be in standby when the CODEC is idle and can have active widgets without being in full power mode but the shutdown functionality assumes these things. Add checks for the bias level at each stage so that we don't do transitions other than the ON->PREPARE->STANDBY->OFF ones that the drivers are expecting.
