| e9e3bce | Eric Sandeen | 12 February 2011, 13:17:34 UTC | ext4: serialize unaligned asynchronous DIO ext4 has a data corruption case when doing non-block-aligned asynchronous direct IO into a sparse file, as demonstrated by xfstest 240. The root cause is that while ext4 preallocates space in the hole, mappings of that space still look "new" and dio_zero_block() will zero out the unwritten portions. When more than one AIO thread is going, they both find this "new" block and race to zero out their portion; this is uncoordinated and causes data corruption. Dave Chinner fixed this for xfs by simply serializing all unaligned asynchronous direct IO. I've done the same here. The difference is that we only wait on conversions, not all IO. This is a very big hammer, and I'm not very pleased with stuffing this into ext4_file_write(). But since ext4 is DIO_LOCKING, we need to serialize it at this high level. I tried to move this into ext4_ext_direct_IO, but by then we have the i_mutex already, and we will wait on the work queue to do conversions - which must also take the i_mutex. So that won't work. This was originally exposed by qemu-kvm installing to a raw disk image with a normal sector-63 alignment. I've tested a backport of this patch with qemu, and it does avoid the corruption. It is also quite a lot slower (14 min for package installs, vs. 8 min for well-aligned) but I'll take slow correctness over fast corruption any day. Mingming suggested that we can track outstanding conversions, and wait on those so that non-sparse files won't be affected, and I've implemented that here; unaligned AIO to nonsparse files won't take a perf hit.

| 2892c15 | Eric Sandeen | 12 February 2011, 13:12:18 UTC | ext4: make grpinfo slab cache names static In 2.6.37 I was running into oopses with repeated module loads & unloads. I tracked this down to: fb1813f4 ext4: use dedicated slab caches for group_info structures (this was in addition to the features advert unload problem) The kstrdup & subsequent kfree of the cache name was causing a double free. In slub, at least, if I read it right it allocates & frees the name itself, slab seems to do something different... so in slub I think we were leaking -our- cachep->name, and double freeing the one allocated by slub. After getting lost in slab/slub/slob a bit, I just looked at other sized-caches that get allocated. jbd2, biovec, sgpool all do it more or less the way jbd2 does. Below patch follows the jbd2 method of dynamically allocating a cache at mount time from a list of static names. (This might also possibly fix a race creating the caches with parallel mounts running).

It meant to break out of this loop when no pages had been reclaimed and not a single page was even scanned. The way it would detect the latter is by taking a snapshot of sc->nr_scanned at the beginning of the function and comparing it against the new sc->nr_scanned after the scan loop. But it would re-iterate without updating that snapshot, looping forever if sc->nr_scanned changed at least once since shrink_zone() was invoked. This is not the sole condition that would exit that loop, but it requires other processes to change the zone state, as the reclaimer that is stuck obviously can not anymore. This is only happening for higher-order allocations, where reclaim is run back to back with compaction.

| e15f8c0 | Michel Lespinasse | 10 February 2011, 23:01:32 UTC | mlock: fix race when munlocking pages in do_wp_page() vmscan can lazily find pages that are mapped within VM_LOCKED vmas, and set the PageMlocked bit on these pages, transfering them onto the unevictable list. When do_wp_page() breaks COW within a VM_LOCKED vma, it may need to clear PageMlocked on the old page and set it on the new page instead. This change fixes an issue where do_wp_page() was clearing PageMlocked on the old page while the pte was still pointing to it (as well as rmap). Therefore, we were not protected against vmscan immediately transfering the old page back onto the unevictable list. This could cause pages to get stranded there forever. I propose to move the corresponding code to the end of do_wp_page(), after the pte (and rmap) have been pointed to the new page. Additionally, we can use munlock_vma_page() instead of clear_page_mlock(), so that the old page stays mlocked if there are still other VM_LOCKED vmas mapping it.

However, that other ioctl blocks, waiting for the module-level mutex that replaced the BKL, and then we're stuck. This patch removes the module-level mutex altogether. It's clearly wrong, and as far as I can see, it's entirely unnecessary, since the nbd driver maintains per-device mutexes, and I don't see anything that would require a module-level (or kernel-level, for that matter) mutex.

| 01e05e9 | Tejun Heo | 10 February 2011, 23:01:22 UTC | ptrace: use safer wake up on ptrace_detach() The wake_up_process() call in ptrace_detach() is spurious and not interlocked with the tracee state. IOW, the tracee could be running or sleeping in any place in the kernel by the time wake_up_process() is called. This can lead to the tracee waking up unexpectedly which can be dangerous. The wake_up is spurious and should be removed but for now reduce its toxicity by only waking up if the tracee is in TRACED or STOPPED state. This bug can possibly be used as an attack vector. I don't think it will take too much effort to come up with an attack which triggers oops somewhere. Most sleeps are wrapped in condition test loops and should be safe but we have quite a number of places where sleep and wakeup conditions are expected to be interlocked. Although the window of opportunity is tiny, ptrace can be used by non-privileged users and with some loading the window can definitely be extended and exploited.

It causes a crash when we rmmod immediately after we umount the volume[1]. So we need to call rcu_barrier after we kill_sb so that the inode is freed before we do rmmod. The idea is inspired by Aneesh Kumar. rcu_barrier will wait for all callbacks to end before preceding. The original patch was done by Tao Ma, but synchronize_rcu() is not enough here. 1. http://marc.info/?l=linux-fsdevel&m=129680863330185&w=2 Tested-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Cc: Nick Piggin <npiggin@kernel.dk> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Chris Mason <chris.mason@oracle.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> | 12 February 2011, 00:12:19 UTC |
| 2dab597 | Linus Torvalds | 11 February 2011, 23:53:38 UTC | Fix possible filp_cachep memory corruption In commit 31e6b01f4183 ("fs: rcu-walk for path lookup") we started doing path lookup using RCU, which then falls back to a careful non-RCU lookup in case of problems (LOOKUP_REVAL). So do_filp_open() has this "re-do the lookup carefully" looping case. However, that means that we must not release the open-intent file data if we are going to loop around and use it once more! Fix this by moving the release of the open-intent data to the function that allocates it (do_filp_open() itself) rather than the helper functions that can get called multiple times (finish_open() and do_last()). This makes the logic for the lifetime of that field much more obvious, and avoids the possible double free. Reported-by: J. R.

Also, remove the FIXME comment and replace it with the explanation that Steve gave earlier. After receiving a packet, we currently check the header. If it's no good, then we toss it out and continue the loop, leaving the caller waiting on that response. In cases where the packet has length inconsistencies, but the MID is valid, this leads to unneeded delays. That's especially problematic now that the client waits indefinitely for responses. Instead, don't immediately discard the packet if checkSMB fails. Try to find a matching mid_q_entry, mark it as having a malformed response and issue the callback.

| 02a8f01 | Justin TerAvest | 09 February 2011, 13:20:03 UTC | cfq-iosched: Don't wait if queue already has requests. Commit 7667aa0630407bc07dc38dcc79d29cc0a65553c1 added logic to wait for the last queue of the group to become busy (have at least one request), so that the group does not lose out for not being continuously backlogged. The commit did not check for the condition that the last queue already has some requests. As a result, if the queue already has requests, wait_busy is set. Later on, cfq_select_queue() checks the flag, and decides that since the queue has a request now and wait_busy is set, the queue is expired. This results in early expiration of the queue. This patch fixes the problem by adding a check to see if queue already has requests. If it does, wait_busy is not set. As a result, time slices do not expire early. The queues with more than one request are usually buffered writers. Testing shows improvement in isolation between buffered writers.

| 8d3bdbd | David S. Miller | 08 February 2011, 23:02:50 UTC | net: Fix lockdep regression caused by initializing netdev queues too early. In commit aa9421041128abb4d269ee1dc502ff65fb3b7d69 ("net: init ingress queue") we moved the allocation and lock initialization of the queues into alloc_netdev_mq() since register_netdevice() is way too late. The problem is that dev->type is not setup until the setup() callback is invoked by alloc_netdev_mq(), and the dev->type is what determines the lockdep class to use for the locks in the queues. Fix this by doing the queue allocation after the setup() callback runs. This is safe because the setup() callback is not allowed to make any state changes that need to be undone on error (memory allocations, etc.). It may, however, make state changes that are undone by free_netdev() (such as netif_napi_add(), which is done by the ipoib driver's setup routine). The previous code also leaked a reference to the &init_net namespace object on RX/TX queue allocation failures. Signed-off-by: David S. Miller <davem@davemloft.net> | 08 February 2011, 23:02:50 UTC |

There is no cleanup mechanism available at this point. So we have to add the caif private instance to the global list once we are sure that register_netdev() has succedded in ->newlink(). Otherwise, if register_netdev() fails, the caller will invoke free_netdev() and we will have a reference to freed up memory on the chnl_net_list. Signed-off-by: David S.
