2010-02-05CS5536: apply pci quirk for BIOS SMBUS bugAndres Salomon
The new cs5535-* drivers use PCI header config info rather than MSRs to determine the memory region to use for things like GPIOs and MFGPTs. As anticipated, we've run into a buggy BIOS: [ 0.081818] pci 0000:00:14.0: reg 10: [io 0x6000-0x7fff] [ 0.081906] pci 0000:00:14.0: reg 14: [io 0x6100-0x61ff] [ 0.082015] pci 0000:00:14.0: reg 18: [io 0x6200-0x63ff] [ 0.082917] pci 0000:00:14.2: reg 20: [io 0xe000-0xe00f] [ 0.083551] pci 0000:00:15.0: reg 10: [mem 0xa0010000-0xa0010fff] [ 0.084436] pci 0000:00:15.1: reg 10: [mem 0xa0011000-0xa0011fff] [ 0.088816] PCI: pci_cache_line_size set to 32 bytes [ 0.088938] pci 0000:00:14.0: address space collision: [io 0x6100-0x61ff] already in use [ 0.089052] pci 0000:00:14.0: can't reserve [io 0x6100-0x61ff] This is a Soekris board, and its BIOS sets the size of the PCI ISA bridge device's BAR0 to 8k. In reality, it should be 8 bytes (BAR0 is used for SMBus stuff). This quirk checks for an incorrect size, and resets it accordingly.

2010-02-04Btrfs: do not try and lookup the file extent when finishing ordered ioJosef Bacik
When running the following fio job [torrent] filename=torrent-test rw=randwrite size=4g filesize=4g bs=4k ioengine=sync you would see long stalls where no work was being done. That is because we were doing all this extra work to read in the file extent outside of the transaction, however in the random io case this ends up hurting us because the file extents are not there to begin with. So axe this logic, since we end up reading in the file extent when we go to update it anyway. This took the fio job from 11 mb/s with several ~10 second stalls to 24 mb/s to a couple of 1-2 second stalls.

2010-02-04Btrfs: remove BUG_ON() due to mounting bad filesystemMiao Xie
Mounting a bad filesystem caused a BUG_ON(). The following is steps to reproduce it. # mkfs.btrfs /dev/sda2 # mount /dev/sda2 /mnt # mkfs.btrfs /dev/sda1 /dev/sda2 (the program says that /dev/sda2 was mounted, and then exits. ) # umount /mnt # mount /dev/sda1 /mnt At the third step, mkfs.btrfs exited in the way of make filesystem. So the initialization of the filesystem didn't finish. So the filesystem was bad, and it caused BUG_ON() when mounting it. But BUG_ON() should be called by the wrong code, not user's operation, so I think it is a bug of btrfs. This patch fixes it.

Currently the omap serial clocks are autoidled after 5 seconds. However, this causes lost characters on the serial ports. As this is considered non-standard behaviour for Linux, disable the timeout. Note that this will also cause blocking of any deeper omap sleep states. To enable the autoidling of the serial ports, do something like this for each serial port: # echo 5 > /sys/devices/platform/serial8250.0/sleep_timeout # echo 5 > /sys/devices/platform/serial8250.1/sleep_timeout ...

2010-02-03futex: Handle futex value corruption gracefullyThomas Gleixner
The WARN_ON in lookup_pi_state which complains about a mismatch between pi_state->owner->pid and the pid which we retrieved from the user space futex is completely bogus. The code just emits the warning and then continues despite the fact that it detected an inconsistent state of the futex. A conveniant way for user space to spam the syslog. Replace the WARN_ON by a consistency check. If the values do not match return -EINVAL and let user space deal with the mess it created. This also fixes the missing task_pid_vnr() when we compare the pi_state->owner pid with the futex value.

2010-02-03futex: Handle user space corruption gracefullyThomas Gleixner
If the owner of a PI futex dies we fix up the pi_state and set pi_state->owner to NULL. When a malicious or just sloppy programmed user space application sets the futex value to 0 e.g. by calling pthread_mutex_init(), then the futex can be acquired again. A new waiter manages to enqueue itself on the pi_state w/o damage, but on unlock the kernel dereferences pi_state->owner and oopses. Prevent this by checking pi_state->owner in the unlock path. If pi_state->owner is not current we know that user space manipulated the futex value. Ignore the mess and return -EINVAL. This catches the above case and also the case where a task hijacks the futex by setting the tid value and then tries to unlock it.

2010-02-03futex_lock_pi() key refcnt fixMikael Pettersson
This fixes a futex key reference count bug in futex_lock_pi(), where a key's reference count is incremented twice but decremented only once, causing the backing object to not be released. If the futex is created in a temporary file in an ext3 file system, this bug causes the file's inode to become an "undead" orphan, which causes an oops from a BUG_ON() in ext3_put_super() when the file system is unmounted. glibc's test suite is known to trigger this, see <http://bugzilla.kernel.org/show_bug.cgi?id=14256>. The bug is a regression from 2.6.28-git3, namely Peter Zijlstra's 38d47c1b7075bd7ec3881141bb3629da58f88dab "[PATCH] futex: rely on get_user_pages() for shared futexes". That commit made get_futex_key() also increment the reference count of the futex key, and updated its callers to decrement the key's reference count before returning. Unfortunately the normal exit path in futex_lock_pi() wasn't corrected: the reference count is incremented by get_futex_key() and queue_lock(), but the normal exit path only decrements once, via unqueue_me_pi(). The fix is to put_futex_key() after unqueue_me_pi(), since 2.6.31 this is easily done by 'goto out_put_key' rather than 'goto out'.

2010-02-03NFS: Fix an Oops when truncating a fileTrond Myklebust
The VM/VFS does not allow mapping->a_ops->invalidatepage() to fail. Unfortunately, nfs_wb_page_cancel() may fail if a fatal signal occurs. Since the NFS code assumes that the page stays mapped for as long as the writeback is active, we can end up Oopsing (among other things). The only safe fix here is to convert nfs_wait_on_request(), so as to make it uninterruptible (as is already the case with wait_on_page_writeback()).

2010-02-03GFS2: Extend umount wait coverage to full glock lifetimeSteven Whitehouse
Although all glocks are, by the time of the umount glock wait, scheduled for demotion, some of them haven't made it far enough through the process for the original set of waiting code to wait for them. This extends the ref count to the whole glock lifetime in order to ensure that the waiting does catch all glocks.
