2017-01-30net/mlx4_core: Avoid command timeouts during VF driver device shutdownJack Morgenstein3-1/+14
Some Hypervisors detach VFs from VMs by instantly causing an FLR event to be generated for a VF. In the mlx4 case, this will cause that VF's comm channel to be disabled before the VM has an opportunity to invoke the VF device's "shutdown" method. The result is that the VF driver on the VM will experience a command timeout during the shutdown process when the Hypervisor does not deliver a command-completion event to the VM. To avoid FW command timeouts on the VM when the driver's shutdown method is invoked, we detect the absence of the VF's comm channel at the very start of the shutdown process. If the comm-channel has already been disabled, we cause all FW commands during the device shutdown process to immediately return success (and thus avoid all command timeouts).

2017-01-30gianfar: synchronize DMA API usage by free_skb_rx_queue w/ gfar_new_pageArseny Solokha1-2/+2
In spite of switching to paged allocation of Rx buffers, the driver still called dma_unmap_single() in the Rx queues tear-down path. The DMA region unmapping code in free_skb_rx_queue() basically predates the introduction of paged allocation to the driver. While being refactored, it apparently hasn't reflected the change in the DMA API usage by its counterpart gfar_new_page(). As a result, setting an interface to the DOWN state now yields the following: # ip link set eth2 down fsl-gianfar ffe24000.ethernet: DMA-API: device driver frees DMA memory with wrong function [device address=0x000000001ecd0000] [size=40] ------------[ cut here ]------------ WARNING: CPU: 1 PID: 189 at lib/dma-debug.c:1123 check_unmap+0x8e0/0xa28 CPU: 1 PID: 189 Comm: ip Tainted: G O 4.9.5 #1 task: dee73400 task.stack: dede2000 NIP: c02101e8 LR: c02101e8 CTR: c0260d74 REGS: dede3bb0 TRAP: 0700 Tainted: G O (4.9.5) MSR: 00021000 <CE,ME> CR: 28002222 XER: 00000000 GPR00: c02101e8 dede3c60 dee73400 000000b6 dfbd033c dfbd36c4 1f622000 dede2000 GPR08: 00000007 c05b1634 1f622000 00000000 22002484 100a9904 00000000 00000000 GPR16: 00000000 db4c849c 00000002 db4c8480 00000001 df142240 db4c84bc 00000000 GPR24: c0706148 c0700000 00029000 c07552e8 c07323b4 dede3cb8 c07605e0 db535540 NIP [c02101e8] check_unmap+0x8e0/0xa28 LR [c02101e8] check_unmap+0x8e0/0xa28 Call Trace: [dede3c60] [c02101e8] check_unmap+0x8e0/0xa28 (unreliable) [dede3cb0] [c02103b8] debug_dma_unmap_page+0x88/0x9c [dede3d30] [c02dffbc] free_skb_resources+0x2c4/0x404 [dede3d80] [c02e39b4] gfar_close+0x24/0xc8 [dede3da0] [c0361550] __dev_close_many+0xa0/0xf8 [dede3dd0] [c03616f0] __dev_close+0x2c/0x4c [dede3df0] [c036b1b8] __dev_change_flags+0xa0/0x174 [dede3e10] [c036b2ac] dev_change_flags+0x20/0x60 [dede3e30] [c03e130c] devinet_ioctl+0x540/0x824 [dede3e90] [c0347dcc] sock_ioctl+0x134/0x298 [dede3eb0] [c0111814] do_vfs_ioctl+0xac/0x854 [dede3f20] [c0111ffc] SyS_ioctl+0x40/0x74 [dede3f40] [c000f290] ret_from_syscall+0x0/0x3c --- interrupt: c01 at 0xff45da0 LR = 0xff45cd0 Instruction dump: 811d001c 7c66482e 813d0020 9061000c 807f000c 5463103a 7cc6182e 3c60c052 386309ac 90c10008 4cc63182 4826b845 <0fe00000> 4bfffa60 3c80c052 388402c4 ---[ end trace 695ae6d7ac1d0c47 ]--- Mapped at: [<c02e22a8>] gfar_alloc_rx_buffs+0x178/0x248 [<c02e3ef0>] startup_gfar+0x368/0x570 [<c036aeb4>] __dev_open+0xdc/0x150 [<c036b1b8>] __dev_change_flags+0xa0/0x174 [<c036b2ac>] dev_change_flags+0x20/0x60 Even though the issue was discovered in 4.9 kernel, the code in question is identical in the current net and net-next trees.

Note that this fix just prevents kernel to crash, but doesn't make any difference to the existing logic. It means the last caller will win the trade and debounce value will be configured accordingly.

2017-01-30perf/core: Fix use-after-free bugPeter Zijlstra1-2/+25
Dmitry reported a KASAN use-after-free on event->group_leader. It turns out there's a hole in perf_remove_from_context() due to event_function_call() not calling its function when the task associated with the event is already dead. In this case the event will have been detached from the task, but the grouping will have been retained, such that group operations might still work properly while there are live child events etc. This does however mean that we can miss a perf_group_detach() call when the group decomposes, this in turn can then lead to use-after-free. Fix it by explicitly doing the group detach if its still required.

2017-01-30x86/microcode: Do not access the initrd after it has been freedBorislav Petkov3-7/+21
When we look for microcode blobs, we first try builtin and if that doesn't succeed, we fallback to the initrd supplied to the kernel. However, at some point doing boot, that initrd gets jettisoned and we shouldn't access it anymore. But we do, as the below KASAN report shows. That's because find_microcode_in_initrd() doesn't check whether the initrd is still valid or not. So do that. ================================================================== BUG: KASAN: use-after-free in find_cpio_data Read of size 1 by task swapper/1/0 page:ffffea0000db9d40 count:0 mapcount:0 mapping: (null) index:0x1 flags: 0x100000000000000() raw: 0100000000000000 0000000000000000 0000000000000001 00000000ffffffff raw: dead000000000100 dead000000000200 0000000000000000 0000000000000000 page dumped because: kasan: bad access detected CPU: 1 PID: 0 Comm: swapper/1 Tainted: G W 4.10.0-rc5-debug-00075-g2dbde22 #3 Hardware name: Dell Inc.

Commit 07fe64ba213f ("pinctrl: sunxi: Handle bias disable") actually enforced enforced the disabling of the pull up/down resistors instead of ignoring it like it was done before. This was part of a wider rework to switch to the generic pinconf bindings, and was meant to be merged together with DT patches that were switching to it, and removing what was considered default values by both the binding and the boards. This included no bias on a pin. However, those DT patches were delayed to 4.11, which would be fine only for a significant number boards having the bias setup wrong, which in turns break the MMC on those boards (and possibly other devices too). In order to avoid conflicts as much as possible, bring back the old behaviour for 4.10, and we'll revert that commit once all the DT bits will have landed.

2017-01-29stmmac: Discard masked flags in interrupt status registerAlexey Brodkin1-0/+4
DW GMAC databook says the following about bits in "Register 15 (Interrupt Mask Register)": --------------------------->8------------------------- When set, this bit __disables_the_assertion_of_the_interrupt_signal__ because of the setting of XXX bit in Register 14 (Interrupt Status Register). --------------------------->8------------------------- In fact even if we mask one bit in the mask register it doesn't prevent corresponding bit to appear in the status register, it only disables interrupt generation for corresponding event. But currently we expect a bit different behavior: status bits to be in sync with their masks, i.e. if mask for bit A is set in the mask register then bit A won't appear in the interrupt status register. This was proven to be incorrect assumption, see discussion here [1]. That misunderstanding causes unexpected behaviour of the GMAC, for example we were happy enough to just see bogus messages about link state changes. So from now on we'll be only checking bits that really may trigger an interrupt.

I've seen this trigger twice now, where the i915_gem_object_to_ggtt() call in intel_unpin_fb_obj() returns NULL, resulting in an oops immediately afterwards as the (inlined) call to i915_vma_unpin_fence() tries to dereference it. It seems to be some race condition where the object is going away at shutdown time, since both times happened when shutting down the X server.

Modifying TIR hash should change selected fields bitmask in addition to the function and key.

When tunneling is used, some virtualizations systems set the (mlx5e) uplink device to be stacked under upper devices such as bridge or ovs internal port, where the VTEP IP address used for the encapsulation is set on that upper device. In order to support such use-cases, we also deal with a setup where the egress mirred device isn't representing a port on the HW e-switch to where the ingress device belongs.

2017-01-28percpu-refcount: fix reference leak during percpu-atomic transitionDouglas Miller1-2/+2
percpu_ref_tryget() and percpu_ref_tryget_live() should return "true" IFF they acquire a reference. But the return value from atomic_long_inc_not_zero() is a long and may have high bits set, e.g. PERCPU_COUNT_BIAS, and the return value of the tryget routines is bool so the reference may actually be acquired but the routines return "false" which results in a reference leak since the caller assumes it does not need to do a corresponding percpu_ref_put(). This was seen when performing CPU hotplug during I/O, as hangs in blk_mq_freeze_queue_wait where percpu_ref_kill (blk_mq_freeze_queue_start) raced with percpu_ref_tryget (blk_mq_timeout_work). Sample stack trace: __switch_to+0x2c0/0x450 __schedule+0x2f8/0x970 schedule+0x48/0xc0 blk_mq_freeze_queue_wait+0x94/0x120 blk_mq_queue_reinit_work+0xb8/0x180 blk_mq_queue_reinit_prepare+0x84/0xa0 cpuhp_invoke_callback+0x17c/0x600 cpuhp_up_callbacks+0x58/0x150 _cpu_up+0xf0/0x1c0 do_cpu_up+0x120/0x150 cpu_subsys_online+0x64/0xe0 device_online+0xb4/0x120 online_store+0xb4/0xc0 dev_attr_store+0x68/0xa0 sysfs_kf_write+0x80/0xb0 kernfs_fop_write+0x17c/0x250 __vfs_write+0x6c/0x1e0 vfs_write+0xd0/0x270 SyS_write+0x6c/0x110 system_call+0x38/0xe0 Examination of the queue showed a single reference (no PERCPU_COUNT_BIAS, and __PERCPU_REF_DEAD, __PERCPU_REF_ATOMIC set) and no requests. However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0 and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set. The fix is to make the tryget routines use an actual boolean internally instead of the atomic long result truncated to a int.

2017-01-28x86/efi: Always map the first physical page into the EFI pagetablesJiri Kosina1-0/+16
Commit: 129766708 ("x86/efi: Only map RAM into EFI page tables if in mixed-mode") stopped creating 1:1 mappings for all RAM, when running in native 64-bit mode. It turns out though that there are 64-bit EFI implementations in the wild (this particular problem has been reported on a Lenovo Yoga 710-11IKB), which still make use of the first physical page for their own private use, even though they explicitly mark it EFI_CONVENTIONAL_MEMORY in the memory map. In case there is no mapping for this particular frame in the EFI pagetables, as soon as firmware tries to make use of it, a triple fault occurs and the system reboots (in case of the Yoga 710-11IKB this is very early during bootup). Fix that by always mapping the first page of physical memory into the EFI pagetables. We're free to hand this page to the BIOS, as trim_bios_range() will reserve the first page and isolate it away from memory allocators anyway. Note that just reverting 129766708 alone is not enough on v4.9-rc1+ to fix the regression on affected hardware, as this commit: ab72a27da ("x86/efi: Consolidate region mapping logic") later made the first physical frame not to be mapped anyway.

2017-01-27PCI/ASPM: Handle PCI-to-PCIe bridges as roots of PCIe hierarchiesBjorn Helgaas1-6/+13
In a struct pcie_link_state, link->root points to the pcie_link_state of the root of the PCIe hierarchy. For the topmost link, this points to itself (link->root = link). For others, we copy the pointer from the parent (link->root = link->parent->root). Previously we recognized that Root Ports originated PCIe hierarchies, but we treated PCI/PCI-X to PCIe Bridges as being in the middle of the hierarchy, and when we tried to copy the pointer from link->parent->root, there was no parent, and we dereferenced a NULL pointer: BUG: unable to handle kernel NULL pointer dereference at 0000000000000090 IP: [<ffffffff9e424350>] pcie_aspm_init_link_state+0x170/0x820 Recognize that PCI/PCI-X to PCIe Bridges originate PCIe hierarchies just like Root Ports do, so link->root for these devices should also point to itself.
