31a78f2 Balbir Singh 28 September 2008, 22:09:31 UTC mm owner: fix race between swapoff and exit There's a race between mm->owner assignment and swapoff, more easily seen when task slab poisoning is turned on. The condition occurs when try_to_unuse() runs in parallel with an exiting task. A similar race can occur with callers of get_task_mm(), such as /proc/<pid>/<mmstats> or ptrace or page migration. CPU0 CPU1 try_to_unuse looks at mm = task0->mm increments mm->mm_users task 0 exits mm->owner needs to be updated, but no new owner is found (mm_users > 1, but no other task has task->mm = task0->mm) mm_update_next_owner() leaves mmput(mm) decrements mm->mm_users task0 freed dereferencing mm->owner fails The fix is to notify the subsystem via mm_owner_changed callback(), if no new owner is found, by specifying the new task as NULL. Jiri Slaby: mm->owner was set to NULL prior to calling cgroup_mm_owner_callbacks(), but must be set after that, so as not to pass NULL as old owner causing oops. Daisuke Nishimura: mm_update_next_owner() may set mm->owner to NULL, but mem_cgroup_from_task() and its callers need to take account of this situation to avoid oops. Hugh Dickins: Lockdep warning and hang below exec_mmap() when testing these patches. exit_mm() up_reads mmap_sem before calling mm_update_next_owner(), so exec_mmap() now needs to do the same. And with that repositioning, there's now no point in mm_need_new_owner() allowing for NULL mm.

d0185c0 Linus Torvalds 29 September 2008, 14:42:57 UTC Fix NULL pointer dereference in proc_sys_compare The VFS interface for the 'd_compare()' is a bit special (read: 'odd'), because it really just essentially replaces a memcmp(). The filesystem is supposed to just compare the two names with whatever case-independent or other function. And when I say 'is supposed to', I obviously mean that 'procfs does odd things, and actually looks at the dentry that we don't even pass down, rather than just the name'. Which results in problems, because we actually call d_compare before we have even verified that the dentry is still hashed at all. And that causes a problm since the inode that procfs looks at may have been free'd and the d_inode pointer is NULL. procfs just assumes that all dentries are positive, since procfs itself never generates a negative one. But memory pressure will still result in the dentry getting torn down, and as it is removed by RCU, it still remains visible on some lists - and to d_compare. If the filesystem just did a name comparison, we wouldn't care. And we could just fix procfs to know about negative dentries too. But rather than have the low-level filesystems know about internal VFS details, just move the check for a unhashed dentry up a bit, so that we will only call d_compare on dentries that are still active. The actual oops this caused didn't look like a NULL pointer dereference because procfs did a 'container_of(inode, struct proc_inode, vfs_inode)' to get at its internal proc_inode information from the inode pointer, and accessed a field below the inode. So the oops would look something like BUG: unable to handle kernel paging request at fffffffffffffff0 IP: [<ffffffff802bc6c6>] proc_sys_compare+0x36/0x50 and was seen on both x86-64 (Alexey Dobriyan and Hugh Dickins) and ppc64 (Hugh Dickins).

ec2cd95 Timur Tabi 29 July 2008, 21:35:52 UTC ALSA: make the CS4270 driver a new-style I2C driver Update the CS4270 ALSA device driver to use the new-style I2C interface. Starting with the 2.6.27 PowerPC kernel, I2C devices that have entries in the device trees can no longer be probed by old-style I2C drivers. The device tree for Freescale MPC8610 HPCD has included an entry for the CS4270 since 2.6.25, but that entry was previously ignored by the PowerPC I2C subsystem. Since that's no longer the case, the best solution is to update the CS4270 driver to a new-style interface, rather than try to revert the behavior of new PowerPC I2C subsystem.

d7161a6 Jason Wessel 26 September 2008, 15:36:41 UTC kgdb, x86, arm, mips, powerpc: ignore user space single stepping On the x86 arch, user space single step exceptions should be ignored if they occur in the kernel space, such as ptrace stepping through a system call. First check if it is kgdb that is executing a single step, then ensure it is not an accidental traversal into the user space, while in kgdb, any other time the TIF_SINGLESTEP is set, kgdb should ignore the exception. On x86, arm, mips and powerpc, the kgdb_contthread usage was inconsistent with the way single stepping is implemented in the kgdb core. The arch specific stub should always set the kgdb_cpu_doing_single_step correctly if it is single stepping. This allows kgdb to correctly process an instruction steps if ptrace happens to be requesting an instruction step over a system call.

71a8c87 Lachlan McIlroy 26 September 2008, 02:17:57 UTC [XFS] Remove xfs_iext_irec_compact_full() Yet another bug was found in xfs_iext_irec_compact_full() and while the source of the bug was found it wasn't an easy task to track it down because the conditions are very difficult to reproduce. A HUGE thank-you goes to Russell Cattelan and Eric Sandeen for their significant effort in tracking down the source of this corruption. xfs_iext_irec_compact_full() and xfs_iext_irec_compact_pages() are almost identical - they both compact indirect extent lists by moving extents from subsequent buffers into earlier ones. xfs_iext_irec_compact_pages() only moves extents if all of the extents in the next buffer will fit into the empty space in the buffer before it. xfs_iext_irec_compact_full() will go a step further and move part of the next buffer if all the extents wont fit. It will then shift the remaining extents in the next buffer up to the start of the buffer. The bug here was that we did not update er_extoff and this caused extent list corruption. It does not appear that this extra functionality gains us much. Calling xfs_iext_irec_compact_pages() instead will do a good enough job at compacting the indirect list and will be quicker too. For the case in xfs_iext_indirect_to_direct() the total number of extents in the indirect list will fit into one buffer so we will never need the extra functionality of xfs_iext_irec_compact_full() there. Also xfs_iext_irec_compact_pages() doesn't need to do a memmove() (the buffers will never overlap) so we don't want the performance hit that can incur.

6ef190c Roland Dreier 25 September 2008, 22:28:08 UTC IPoIB: Fix crash when path record fails after path flush Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") changed how paths are flushed on an SM event. This change introduces a problem if the path record query triggered by fails, causing path->ah to become NULL. A later successful path query will then trigger WARN_ON() in path_rec_completion(), and crash because path->ah has already been freed, so the ipoib_put_ah() inside the lock in path_rec_completion() may actually drop the last reference (contrary to the comment that claims this is safe). Fix this by updating path->ah and freeing old_ah only when the path record query is successful. This prevents the neighbour AH and that path AH from getting out of sync.

After that, polling is stopped and the trans is destroyed. This sequence has a few problems. * Read and write works were never cancelled and the p9_conn can be destroyed while the works are running as r/w works remove requests from the list and dereference the p9_conn from them. * The list emptiness wait using p9_conn->equeue wouldn't trigger because p9_conn_cancel() always clears all the lists and the only way the wait can be triggered is to have another task to issue a request between the slim window between p9_conn_cancel() and the wait, which isn't safe under the current implementation with or without the wait. This patch fixes the problem by first stopping poll, which can schedule r/w works, first and cancle r/w works which guarantees that r/w works are not and will not run from that point and then calling p9_conn_cancel() and do the rest of destruction.

5257d97 Alan Stern 22 September 2008, 18:43:08 UTC USB: revert recovery from transient errors This patch (as1135) essentially reverts the major parts of two earlier patches to usbcore, because they ended up causing a regression. Trying to recover from transient communication errors can lead to other problems, because operations that failed during the error period are not always retried. The simplest example is the initial Set-Config request sent after device enumeration; if it gets lost then it will not be retried and the device will remain unconfigured. This patch restores the old behavior in which any port disconnect or port disable causes the entire device structure to be removed, fixing a reported regression.

01c1714 David Brownell 27 August 2008, 06:35:04 UTC USB: fix EHCI periodic transfers As noted by Stefan Neis <Stefan.Neis@kobil.com>, we had a recent regression with EHCI periodic transfers, in some (seemingly not all that common) cases. The root cause was that the schedule activation was only loosely coupled to the addition or removal of transfers, so two different execution contexts could both think they had to deactivate (or conversely activate) the schedule. So this fix tightens that coupling, managing it more like a refcount.

83a7982 Geoff Levand 22 August 2008, 21:13:00 UTC USB: fix hcd interrupt disabling Commit de85422b94ddb23c021126815ea49414047c13dc, 'USB: fix interrupt disabling for HCDs with shared interrupt handlers' changed usb_add_hcd() to strip IRQF_DISABLED from irqflags prior to calling request_irq() with the justification that such a removal was necessary for shared interrupts to work properly. Unfortunately, the change in that commit unconditionally removes the IRQF_DISABLED flag, causing problems on platforms that don't use a shared interrupt but require IRQF_DISABLED. This change adds a check for IRQF_SHARED prior to removing the IRQF_DISABLED flag. Fixes the PS3 system startup hang reported with recent Fedora and OpenSUSE kernels. Note that this problem is hidden when CONFIG_LOCKDEP=y (ps3_defconfig), as local_irq_enable_in_hardirq() is defined as a null statement for that config.

That caused some hangs and crashes, rather than more polite failure modes of a truly halted controller. This patch forces a true halt, and emits a (previously missing) diagnostic.

44ea91c James Bottomley 20 September 2008, 00:31:50 UTC [SCSI] Fix hang with split requests Sometimes, particularly for USB devices with the last sector bug, requests get completed in chunks. There's a bug in this in that if one of the chunks gets an error, we complete that chunk with an error but never move on to the remaining ones, leading to the request hanging (because it's not fully completed). Fix this by completing all remaining chunks if an error is encountered.
