2013-01-27ioat: Fix DMA memory sync direction correct flagShuah Khan
commit ac4989874af56435c308bdde9ad9c837a26f8b23 upstream. ioat does DMA memory sync with DMA_TO_DEVICE direction on a buffer allocated for DMA_FROM_DEVICE dma, resulting in the following warning from dma debug. Fixed the dma_sync_single_for_device() call to use the correct direction.

If cpuidle is disabled, that means that: per_cpu(acpi_cpuidle_device, pr->id) is set to NULL as the acpi_processor_power_init ends up failing at retval = cpuidle_register_driver(&acpi_idle_driver) (in acpi_processor_power_init) and never sets the per_cpu idle device.

2013-01-27SGI-XP: handle non-fatal trapsRobin Holt
commit 891348ca0f66206f1dc0e30d63757e3df1ae2d15 upstream. We found a user code which was raising a divide-by-zero trap. That trap would lead to XPC connections between system-partitions being torn down due to the die_chain notifier callouts it received. This also revealed a different issue where multiple callers into xpc_die_deactivate() would all attempt to do the disconnect in parallel which would sometimes lock up but often overwhelm the console on very large machines as each would print at least one line of output at the end of the deactivate. I reviewed all the users of the die_chain notifier and changed the code to ignore the notifier callouts for reasons which will not actually lead to a system to continue on to call die().

2013-01-27serial: 8250, increase PASS_LIMITJiri Slaby
commit e7328ae1848966181a7ac47e8ae6cddbd2cf55f3 upstream. With virtual machines like qemu, it's pretty common to see "too much work for irq4" messages nowadays. This happens when a bunch of output is printed on the emulated serial console. This is caused by too low PASS_LIMIT. When ISR loops more than the limit, it spits the message. I've been using a kernel with doubled the limit and I couldn't see no problems. Maybe it's time to get rid of the message now?

2013-01-27drivers/firmware/dmi_scan.c: fetch dmi version from SMBIOS if it existsZhenzhong Duan
commit 9f9c9cbb60576a1518d0bf93fb8e499cffccf377 upstream. The right dmi version is in SMBIOS if it's zero in DMI region This issue was originally found from an oracle bug. One customer noticed system UUID doesn't match between dmidecode & uek2. - HP ProLiant BL460c G6 : # cat /sys/devices/virtual/dmi/id/product_uuid 00000000-0000-4C48-3031-4D5030333531 # dmidecode | grep -i uuid UUID: 00000000-0000-484C-3031-4D5030333531 From SMBIOS 2.6 on, spec use little-endian encoding for UUID other than network byte order. So we need to get dmi version to distinguish. If version is 0.0, the real version is taken from the SMBIOS version. This is part of original kernel comment in code.

commit 0f815a0a700bc10547449bde6c106051a035a1b9 upstream. This patch (as1644) fixes a race that occurs during startup in uhci-hcd. If the IRQ line is shared with other devices, it's possible for the handler routine to be called before the data structures are fully initialized. The problem is fixed by adding a check to the IRQ handler routine. If the initialization hasn't finished yet, the routine will return immediately.

commit c1bf08ac26e92122faab9f6c32ea8aba94612dae upstream. If some other kernel subsystem has a module notifier, and adds a kprobe to a ftrace mcount point (now that kprobes work on ftrace points), when the ftrace notifier runs it will fail and disable ftrace, as well as kprobes that are attached to ftrace points.

But this happened before ftrace could have touched the code. As ftrace didn't run yet, the kprobe system had no idea it was a ftrace point and simply added a breakpoint to the code (0xcc in the cc:bb:d2:4b:e1). Then when ftrace went to modify the location from a call to mcount/fentry into a nop, it didn't see a call op, but instead it saw the breakpoint op and not knowing what to do with it, ftrace shut itself down. The solution is to simply give the ftrace module notifier the max priority. This should have been done regardless, as the core code ftrace modification also happens very early on in boot up. This makes the module modification closer to core modification.

2013-01-27drm/i915: Invalidate the relocation presumed_offsets along the slow pathChris Wilson
commit 262b6d363fcff16359c93bd58c297f961f6e6273 upstream. In the slow path, we are forced to copy the relocations prior to acquiring the struct mutex in order to handle pagefaults. We forgo copying the new offsets back into the relocation entries in order to prevent a recursive locking bug should we trigger a pagefault whilst holding the mutex for the reservations of the execbuffer. Therefore, we need to reset the presumed_offsets just in case the objects are rebound back into their old locations after relocating for this exexbuffer - if that were to happen we would assume the relocations were valid and leave the actual pointers to the kernels dangling, instant hang.

commit 1ee4c55fc9620451b2a825d793042a7e0775391b upstream. vt6656 has several headers that use the #pragma pack(1) directive to enable structure packing, but never disable it. The layout of structures defined in other headers can then depend on which order the various headers are included in, breaking the One Definition Rule. In practice this resulted in crashes on x86_64 until the order of header inclusion was changed for some files in commit 11d404cb56ecd ('staging: vt6656: fix headers and add cfg80211.'). But we need a proper fix that won't be affected by future changes to the order of inclusion. This removes the #pragma pack(1) directives and adds __packed to the structure definitions for which packing appears to have been intended.

2013-01-21xen: Fix stack corruption in xen_failsafe_callback for 32bit PVOPS guests.Frediano Ziglio
commit 9174adbee4a9a49d0139f5d71969852b36720809 upstream. This fixes CVE-2013-0190 / XSA-40 There has been an error on the xen_failsafe_callback path for failed iret, which causes the stack pointer to be wrong when entering the iret_exc error path. This can result in the kernel crashing. In the classic kernel case, the relevant code looked a little like: popl %eax # Error code from hypervisor jz 5f addl $16,%esp jmp iret_exc # Hypervisor said iret fault 5: addl $16,%esp # Hypervisor said segment selector fault Here, there are two identical addls on either option of a branch which appears to have been optimised by hoisting it above the jz, and converting it to an lea, which leaves the flags register unaffected. In the PVOPS case, the code looks like: popl_cfi %eax # Error from the hypervisor lea 16(%esp),%esp # Add $16 before choosing fault path CFI_ADJUST_CFA_OFFSET -16 jz 5f addl $16,%esp # Incorrectly adjust %esp again jmp iret_exc It is possible unprivileged userspace applications to cause this behaviour, for example by loading an LDT code selector, then changing the code selector to be not-present. At this point, there is a race condition where it is possible for the hypervisor to return back to userspace from an interrupt, fault on its own iret, and inject a failsafe_callback into the kernel. This bug has been present since the introduction of Xen PVOPS support in commit 5ead97c84 (xen: Core Xen implementation), in 2.6.23.

2013-01-21xhci: fix null-pointer dereference when destroying half-built segment ringsJulius Werner
commit 68e5254adb88bede68285f11fb442a4d34fb550c upstream. xhci_alloc_segments_for_ring() builds a list of xhci_segments and links the tail to head at the end (forming a ring). When it bails out for OOM reasons half-way through, it tries to destroy its half-built list with xhci_free_segments_for_ring(), even though it is not a ring yet. This causes a null-pointer dereference upon hitting the last element. Furthermore, one of its callers (xhci_ring_alloc()) mistakenly believes the output parameters to be valid upon this kind of OOM failure, and calls xhci_ring_free() on them. Since the (incomplete) list/ring should already be destroyed in that case, this would lead to a use after free. This patch fixes those issues by having xhci_alloc_segments_for_ring() destroy its half-built, non-circular list manually and destroying the invalid struct xhci_ring in xhci_ring_alloc() with a plain kfree(). This patch should be backported to kernels as old as 2.6.31, that contains the commit 0ebbab37422315a5d0cb29792271085bafdf38c0 "USB: xhci: Ring allocation and initialization." A separate patch will need to be developed for kernels older than 3.4, since the ring allocation code was refactored in that kernel.

2013-01-21USB: fix endpoint-disabling for failed config changesAlan Stern
commit 36caff5d795429c572443894e8789c2150dd796b upstream. This patch (as1631) fixes a bug that shows up when a config change fails for a device under an xHCI controller. The controller needs to be told to disable the endpoints that have been enabled for the new config. The existing code does this, but before storing the information about which endpoints were enabled! As a result, any second attempt to install the new config is doomed to fail because xhci-hcd will refuse to enable an endpoint that is already enabled. The patch optimistically initializes the new endpoints' device structures before asking the device to switch to the new config. If the request fails then the endpoint information is already stored, so we can use usb_hcd_alloc_bandwidth() to disable the endpoints with no trouble. The rest of the error path is slightly more complex now; we have to disable the new interfaces and call put_device() rather than simply deallocating them.

commit ed4f20943cd4c7b55105c04daedf8d63ab6d499c upstream. Converting a 64 Bit TOD format value to nanoseconds means that the value must be divided by 4.096. In order to achieve that we multiply with 125 and divide by 512. When used within sched_clock() this triggers an overflow after appr. 417 days. Resulting in a sched_clock() return value that is much smaller than previously and therefore may cause all sort of weird things in subsystems that rely on a monotonic sched_clock() behaviour. To fix this implement a tod_to_ns() helper function which converts TOD values without overflow and call this function from both places that open coded the conversion: sched_clock() and kvm_s390_handle_wait().

commit c43435d7722134ed1fda58ce1025f41029bd58ad upstream. comedi_auto_config() associates a Comedi minor device number with an auto-configured hardware device and comedi_auto_unconfig() disassociates it. Currently, these use the hardware device's private data pointer to point to some allocated storage holding the minor device number. This is a bit of a waste of the hardware device's private data pointer, preventing it from being used for something more useful by the low-level comedi device drivers. For example, it would make more sense if comedi_usb_auto_config() was passed a pointer to the struct usb_interface instead of the struct usb_device, but this cannot be done currently because the low-level comedi drivers already use the private data pointer in the struct usb_interface for something more useful. This patch stops the comedi core hijacking the hardware device's private data pointer. Instead, comedi_auto_config() stores a pointer to the hardware device's struct device in the struct comedi_device_file_info associated with the minor device number, and comedi_auto_unconfig() calls new function comedi_find_board_minor() to recover the minor device number associated with the hardware device.

2013-01-17intel-iommu: Free old page tables before creating superpageWoodhouse, David
commit 6491d4d02893d9787ba67279595990217177b351 upstream. The dma_pte_free_pagetable() function will only free a page table page if it is asked to free the *entire* 2MiB range that it covers. So if a page table page was used for one or more small mappings, it's likely to end up still present in the page tables... but with no valid PTEs. This was fine when we'd only be repopulating it with 4KiB PTEs anyway but the same virtual address range can end up being reused for a *large-page* mapping. And in that case were were trying to insert the large page into the second-level page table, and getting a complaint from the sanity check in __domain_mapping() because there was already a corresponding entry. This was *relatively* harmless; it led to a memory leak of the old page table page, but no other ill-effects. Fix it by calling dma_pte_clear_range (hopefully redundant) and dma_pte_free_pagetable() before setting up the new large page.

It was then assuming it would stay attached for the rest of the function. However, without either the log lock being held of the buffer locked, __gfs2_ail_flush() could detach bd at any time. This patch moves the locking before the test. If there isn't a bd already attached, gfs2 can safely allocate one and attach it before locking. There is no way that the newly allocated bd could be on the ail list, and thus no way for __gfs2_ail_flush() to detach it.

commit 55c1945edaac94c5338a3647bc2e85ff75d9cf36 upstream. A high speed control or bulk endpoint may have bInterval set to zero, which means it does not NAK. If bInterval is non-zero, it means the endpoint NAKs at a rate of 2^(bInterval - 1). The xHCI code to compute the NAK interval does not handle the special case of zero properly. The current code unconditionally subtracts one from bInterval and uses it as an exponent. This causes a very large bInterval to be used, and warning messages like these will be printed: usb 1-1: ep 0x1 - rounding interval to 32768 microframes, ep desc says 0 microframes This may cause the xHCI host hardware to reject the Configure Endpoint command, which means the HS device will be unusable under xHCI ports.

commit 1d16638e3b9cc195bac18a8fcbca748f33c1bc24 upstream. If we do have endpoints named like "ep-a" then bEndpointAddress is counted internally by the gadget framework. If we do have endpoints named like "ep-1" then bEndpointAddress is assigned from the digit after "ep-". If we do have both, then it is likely that after we used up the "generic" endpoints we will use the digits and thus assign one bEndpointAddress to multiple endpoints. This theory can be proofed by using the completely enabled g_multi. Without this patch, the mass storage won't enumerate and times out because it shares endpoints with RNDIS. This patch also adds fills up the endpoints list so we have in total endpoints 1 to 15 in + out available while some of them are restricted to certain types like BULK or ISO. Without this change the nokia gadget won't load because the system does not provide enough (BULK) endpoints but it did before ep-a - ep-f were removed.
