de51257 Hugh Dickins 30 July 2010, 17:58:26 UTC mm: fix ia64 crash when gcore reads gate area Debian's ia64 autobuilders have been seeing kernel freeze or reboot when running the gdb testsuite (Debian bug 588574): dannf bisected to 2.6.32 62eede62dafb4a6633eae7ffbeb34c60dba5e7b1 "mm: ZERO_PAGE without PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target. I'd missed updating the gate_vma handling in __get_user_pages(): that happens to use vm_normal_page() (nowadays failing on the zero page), yet reported success even when it failed to get a page - boom when access_process_vm() tried to copy that to its intermediate buffer. Fix this, resisting cleanups: in particular, leave it for now reporting success when not asked to get any pages - very probably safe to change, but let's not risk it without testing exposure. Why did ia64 crash with 16kB pages, but succeed with 64kB pages? Because setup_gate() pads each 64kB of its gate area with zero pages.

This lead to a problem where the wrong per_cpu kmap_high_l1_vipt_depth could be incremented, causing a BUG_ON(*depth <= 0); in kunmap_high_l1_vipt(). The solution is to move the call to smp_processor_id() after the call to preempt_disable().

674b222 Dan Carpenter 13 July 2010, 11:34:59 UTC nfs: include space for the NUL in root path In root_nfs_name() it does the following: if (strlen(buf) + strlen(cp) > NFS_MAXPATHLEN) { printk(KERN_ERR "Root-NFS: Pathname for remote directory too long.\n"); return -1; } sprintf(nfs_export_path, buf, cp); In the original code if (strlen(buf) + strlen(cp) == NFS_MAXPATHLEN) then the sprintf() would lead to an overflow. Generally the rest of the code assumes that the path can have NFS_MAXPATHLEN (1024) characters and a NUL terminator so the fix is to add space to the nfs_export_path[] buffer.

8f92054 David Howells 29 July 2010, 11:45:55 UTC CRED: Fix __task_cred()'s lockdep check and banner comment Fix __task_cred()'s lockdep check by removing the following validation condition: lockdep_tasklist_lock_is_held() as commit_creds() does not take the tasklist_lock, and nor do most of the functions that call it, so this check is pointless and it can prevent detection of the RCU lock not being held if the tasklist_lock is held. Instead, add the following validation condition: task->exit_state >= 0 to permit the access if the target task is dead and therefore unable to change its own credentials. Fix __task_cred()'s comment to: (1) discard the bit that says that the caller must prevent the target task from being deleted. That shouldn't need saying. (2) Add a comment indicating the result of __task_cred() should not be passed directly to get_cred(), but rather than get_task_cred() should be used instead. Also put a note into the documentation to enforce this point there too. Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Paul E.

de09a97 David Howells 29 July 2010, 11:45:49 UTC CRED: Fix get_task_cred() and task_state() to not resurrect dead credentials It's possible for get_task_cred() as it currently stands to 'corrupt' a set of credentials by incrementing their usage count after their replacement by the task being accessed. What happens is that get_task_cred() can race with commit_creds(): TASK_1 TASK_2 RCU_CLEANER -->get_task_cred(TASK_2) rcu_read_lock() __cred = __task_cred(TASK_2) -->commit_creds() old_cred = TASK_2->real_cred TASK_2->real_cred = ... put_cred(old_cred) call_rcu(old_cred) [__cred->usage == 0] get_cred(__cred) [__cred->usage == 1] rcu_read_unlock() -->put_cred_rcu() [__cred->usage == 1] panic() However, since a tasks credentials are generally not changed very often, we can reasonably make use of a loop involving reading the creds pointer and using atomic_inc_not_zero() to attempt to increment it if it hasn't already hit zero. If successful, we can safely return the credentials in the knowledge that, even if the task we're accessing has released them, they haven't gone to the RCU cleanup code. We then change task_state() in procfs to use get_task_cred() rather than calling get_cred() on the result of __task_cred(), as that suffers from the same problem. Without this change, a BUG_ON in __put_cred() or in put_cred_rcu() can be tripped when it is noticed that the usage count is not zero as it ought to be, for example: kernel BUG at kernel/cred.c:168! invalid opcode: 0000 [#1] SMP last sysfs file: /sys/kernel/mm/ksm/run CPU 0 Pid: 2436, comm: master Not tainted 2.6.33.3-85.fc13.x86_64 #1 0HR330/OptiPlex 745 RIP: 0010:[<ffffffff81069881>] [<ffffffff81069881>] __put_cred+0xc/0x45 RSP: 0018:ffff88019e7e9eb8 EFLAGS: 00010202 RAX: 0000000000000001 RBX: ffff880161514480 RCX: 00000000ffffffff RDX: 00000000ffffffff RSI: ffff880140c690c0 RDI: ffff880140c690c0 RBP: ffff88019e7e9eb8 R08: 00000000000000d0 R09: 0000000000000000 R10: 0000000000000001 R11: 0000000000000040 R12: ffff880140c690c0 R13: ffff88019e77aea0 R14: 00007fff336b0a5c R15: 0000000000000001 FS: 00007f12f50d97c0(0000) GS:ffff880007400000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f8f461bc000 CR3: 00000001b26ce000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process master (pid: 2436, threadinfo ffff88019e7e8000, task ffff88019e77aea0) Stack: ffff88019e7e9ec8 ffffffff810698cd ffff88019e7e9ef8 ffffffff81069b45 <0> ffff880161514180 ffff880161514480 ffff880161514180 0000000000000000 <0> ffff88019e7e9f28 ffffffff8106aace 0000000000000001 0000000000000246 Call Trace: [<ffffffff810698cd>] put_cred+0x13/0x15 [<ffffffff81069b45>] commit_creds+0x16b/0x175 [<ffffffff8106aace>] set_current_groups+0x47/0x4e [<ffffffff8106ac89>] sys_setgroups+0xf6/0x105 [<ffffffff81009b02>] system_call_fastpath+0x16/0x1b Code: 48 8d 71 ff e8 7e 4e 15 00 85 c0 78 0b 8b 75 ec 48 89 df e8 ef 4a 15 00 48 83 c4 18 5b c9 c3 55 8b 07 8b 07 48 89 e5 85 c0 74 04 <0f> 0b eb fe 65 48 8b 04 25 00 cc 00 00 48 3b b8 58 04 00 00 75 RIP [<ffffffff81069881>] __put_cred+0xc/0x45 RSP <ffff88019e7e9eb8> ---[ end trace df391256a100ebdd ]--- Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 29 July 2010, 22:16:17 UTC

79f64db Catalin Marinas 28 July 2010, 21:01:55 UTC ARM: 6273/1: Add barriers to the I/O accessors if ARM_DMA_MEM_BUFFERABLE When the coherent DMA buffers are mapped as Normal Non-cacheable (ARM_DMA_MEM_BUFFERABLE enabled), buffer accesses are no longer ordered with Device memory accesses causing failures in device drivers that do not use the mandatory memory barriers before starting a DMA transfer. LKML discussions led to the conclusion that such barriers have to be added to the I/O accessors: http://thread.gmane.org/gmane.linux.kernel/683509/focus=686153 http://thread.gmane.org/gmane.linux.ide/46414 http://thread.gmane.org/gmane.linux.kernel.cross-arch/5250 This patch introduces a wmb() barrier to the write*() I/O accessors to handle the situations where Normal Non-cacheable writes are still in the processor (or L2 cache controller) write buffer before a DMA transfer command is issued. For the read*() accessors, a rmb() is introduced after the I/O to avoid speculative loads where the driver polls for a DMA transfer ready bit.

ba773f7 Jason Wessel 29 July 2010, 00:10:30 UTC x86,kgdb: Fix hw breakpoint regression HW breakpoints events stopped working correctly with kgdb as a result of commit: 018cbffe6819f6f8db20a0a3acd9bab9bfd667e4 (Merge commit 'v2.6.33' into perf/core). The regression occurred because the behavior changed for setting NOTIFY_STOP as the return value to the die notifier if the breakpoint was known to the HW breakpoint API. Because kgdb is using the HW breakpoint API to register HW breakpoints slots, it must also now implement the overflow_handler call back else kgdb does not get to see the events from the die notifier. The kgdb_ll_trap function will be changed to be general purpose code which can allow an easy way to implement the hw_breakpoint API overflow call back.

d2a97a4 Steven Whitehouse 28 July 2010, 16:56:23 UTC GFS2: Use kmalloc when possible for ->readdir() If we don't need a huge amount of memory in ->readdir() then we can use kmalloc rather than vmalloc to allocate it. This should cut down on the greater overheads associated with vmalloc for smaller directories. We may be able to eliminate vmalloc entirely at some stage, but this is easy to do right away. Also using GFP_NOFS to avoid any issues wrt to deleting inodes while under a glock, and suggestion from Linus to factor out the alloc/dealloc. I've given this a test with a variety of different sized directories and it seems to work ok.

The current driver assumes DEFDCDC{2,3} pins are always tied low and thus operates only on DEFDCDC{2,3}_LOW register. This need not always be the case (as is found on OMAP-L138 EVM). Unfortunately, software cannot read the status of DEFDCDC{2,3} pins. So, this information is passed through platform data depending on how the board is wired.

33fea79 Martin Schwidefsky 27 July 2010, 17:29:38 UTC [S390] etr: fix clock synchronization race The etr events switch-to-local and sync-check disable the synchronous clock and schedule a work queue that tries to get the clock back into sync. If another switch-to-local or sync-check event occurs while the work queue function etr_work_fn still runs the eacr.es bit and the clock_sync_word can become inconsistent because check_sync_clock only uses the clock_sync_word to determine if the clock is in sync or not. The second pass of the etr_work_fn will reset the eacr.es bit but will leave the clock_sync_word intact. Fix this race by moving the reset of the eacr.es bit into the switch-to-local and sync-check functions and by checking the eacr.es bit as well to decide if the clock needs to be synced.

We're better off simply returning a failure - the cpufreq core will unregister us cleanly if we end up with no successfully registered CPUs.

47f8bcf Matthew Garrett 20 July 2010, 17:52:00 UTC [CPUFREQ] pcc driver should check for pcch method before calling _OSC The pcc specification documents an _OSC method that's incompatible with the one defined as part of the ACPI spec. This shouldn't be a problem as both are supposed to be guarded with a UUID. Unfortunately approximately nobody (including HP, who wrote this spec) properly check the UUID on entry to the _OSC call. Right now this could result in surprising behaviour if the pcc driver performs an _OSC call on a machine that doesn't implement the pcc specification. Check whether the PCCH method exists first in order to reduce this probability.

96d6523 Eric W. Biederman 08 July 2010, 16:31:24 UTC sysfs: Don't allow the creation of symlinks we can't remove Recently my tagged sysfs support revealed a flaw in the device core that a few rare drivers are running into such that we don't always put network devices in a class subdirectory named net/. Since we are not creating the class directory the network devices wind up in a non-tagged directory, but the symlinks to the network devices from /sys/class/net are in a tagged directory. All of which works until we go to remove or rename the symlink. When we remove or rename a symlink we look in the namespace of the target of the symlink. Since the target of the symlink is in a non-tagged sysfs directory we don't have a namespace to look in, and we fail to remove the symlink. Detect this problem up front and simply don't create symlinks we won't be able to remove later. This prevents symlink leakage and fails in a much clearer and more understandable way.

2d1ee59 Sarah Sharp 09 July 2010, 15:08:54 UTC USB: xhci: Set EP0 dequeue ptr after reset of configured device. When a configured device is reset, the control endpoint's ring is reused. If control transfers to the device were issued before the device is reset, the dequeue pointer will be somewhere in the middle of the ring. If the device is then issued an address with the set address command, the xHCI driver must provide a valid input context for control endpoint zero. The original code would give the hardware the original input context, which had a dequeue pointer set to the top of the ring. This would cause the host to re-execute any control transfers until it reached the ring's enqueue pointer. When issuing a set address command for a device that has just been configured and then reset, use the control endpoint's enqueue pointer as the hardware's dequeue pointer. Assumption: All control transfers will be completed or cancelled before the set address command is issued to the device. If there are any outstanding control transfers, this code will not work.

809cd1c Sarah Sharp 09 July 2010, 15:08:48 UTC USB: Fix USB3.0 Port Speed Downgrade after port reset Without this fix, a USB 3.0 port is downgraded to full speed after a port reset of a configured device. The USB 3.0 terminations will be disabled permanently, and USB 3.0 devices will always enumerate as full speed devices, until the host controller is unplugged (if it is an ExpressCard) or the computer is rebooted. Fajun Chen traced this traced the speed downgrade issue to the port reset and the interpretation of port status in USB hub driver code. The hub code was not testing for the port being a SuperSpeed port, and it fell through to the else case of Full Speed. The following patch adds SuperSpeed mapping from the port status, and fixes the speed downgrade issue.

d1dc908 Sarah Sharp 09 July 2010, 15:08:38 UTC USB: xHCI: Fix another bug in link TRB activation change. Commit 6c12db90f19727c76990e7f4801c67a148b30111 also seems to have introduced a bug that is triggered when the command ring is about to wrap. The inc_enq() function will not have moved the enqueue pointer past the link TRB. It is supposed to be moved past the link TRB in prepare_ring(), which should be called before a TD is enqueued. However, the queue_command() function never calls the prepare_ring() function because prepare_ring() is only supposed to be used for endpoint rings. That means the enqueue pointer will not be moved past the link TRB, and will get overwritten. The fix is to make queue_command() call prepare_ring() with a fake endpoint status (set to running). Then the enqueue pointer will get moved past the link TRB. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> 26 July 2010, 19:00:58 UTC
