2017-07-15saa7134: fix warm Medion 7134 EEPROM readMaciej S. Szmigiero
commit 5a91206ff0d0548939f3e85a65fb76b400fb0e89 upstream. When saa7134 module driving a Medion 7134 card is reloaded reads of this card EEPROM (required for automatic detection of tuner model) will be corrupted due to I2C gate in DVB-T demod being left closed. This sometimes also happens on first saa7134 module load after a warm reboot. Fix this by opening this I2C gate before doing EEPROM read during i2c initialization. Signed-off-by: Maciej S.

2017-07-15staging: comedi: fix clean-up of comedi_class in comedi_init()Ian Abbott
commit a9332e9ad09c2644c99058fcf6ae2f355e93ce74 upstream. There is a clean-up bug in the core comedi module initialization functions, `comedi_init()`. If the `comedi_num_legacy_minors` module parameter is non-zero (and valid), it creates that many "legacy" devices and registers them in SysFS. A failure causes the function to clean up and return an error. Unfortunately, it fails to destroy the "comedi" class that was created earlier. Fix it by adding a call to `class_destroy(comedi_class)` at the appropriate place in the clean-up sequence.

commit 5ecce4c9b17bed4dc9cb58bfb10447307569b77b upstream. The ib_uverbs_create_ah() ind ib_uverbs_modify_qp() calls receive the port number from user input as part of its attributes and assumes it is valid. Down on the stack, that parameter is used to access kernel data structures. If the value is invalid, the kernel accesses memory it should not. To prevent this, verify the port number before using it.

2017-07-15pinctrl: mxs: atomically switch mux and drive strength configUwe Kleine-König
commit da6c2addf66d7ff7d0b090d6267d4292f951e4e6 upstream. To set the mux mode of a pin two bits must be set. Up to now this is implemented using the following idiom: writel(mask, reg + CLR); writel(value, reg + SET); . This however results in the mux mode being 0 between the two writes. On my machine there is an IC's reset pin connected to LCD_D20. The bootloader configures this pin as GPIO output-high (i.e. not holding the IC in reset). When Linux reconfigures the pin to GPIO the short time LCD_D20 is muxed as LCD_D20 instead of GPIO_1_20 is enough to confuse the connected IC. The same problem is present for the pin's drive strength setting which is reset to low drive strength before using the right value. So instead of relying on the hardware to modify the register setting using two writes implement the bit toggling using read-modify-write.

2017-07-15Add USB quirk for HVR-950q to avoid intermittent device resetsDevin Heitmueller
commit 6836796de4019944f4ba4c99a360e8250fd2e735 upstream. The USB core and sysfs will attempt to enumerate certain parameters which are unsupported by the au0828 - causing inconsistent behavior and sometimes causing the chip to reset. Avoid making these calls. This problem manifested as intermittent cases where the au8522 would be reset on analog video startup, in particular when starting up ALSA audio streaming in parallel - the sysfs entries created by snd-usb-audio on streaming startup would result in unsupported control messages being sent during tuning which would put the chip into an unknown state.

2017-07-05iommu: Handle default domain attach failureRobin Murphy
commit 797a8b4d768c58caac58ee3e8cb36a164d1b7751 upstream. We wouldn't normally expect ops->attach_dev() to fail, but on IOMMUs with limited hardware resources, or generally misconfigured systems, it is certainly possible. We report failure correctly from the external iommu_attach_device() interface, but do not do so in iommu_group_add() when attaching to the default domain. The result of failure there is that the device, group and domain all get left in a broken, part-configured state which leads to weird errors and misbehaviour down the line when IOMMU API calls sort-of-but-don't-quite work. Check the return value of __iommu_attach_device() on the default domain, and refactor the error handling paths to cope with its failure and clean up correctly in such cases.

2017-07-05iommu/vt-d: Don't over-free page table directoriesDavid Dillow
commit f7116e115acdd74bc75a4daf6492b11d43505125 upstream. dma_pte_free_level() recurses down the IOMMU page tables and frees directory pages that are entirely contained in the given PFN range. Unfortunately, it incorrectly calculates the starting address covered by the PTE under consideration, which can lead to it clearing an entry that is still in use. This occurs if we have a scatterlist with an entry that has a length greater than 1026 MB and is aligned to 2 MB for both the IOMMU and physical addresses. For example, if __domain_mapping() is asked to map a two-entry scatterlist with 2 MB and 1028 MB segments to PFN 0xffff80000, it will ask if dma_pte_free_pagetable() is asked to PFNs from 0xffff80200 to 0xffffc05ff, it will also incorrectly clear the PFNs from 0xffff80000 to 0xffff801ff because of this issue. The current code will set level_pfn to 0xffff80200, and 0xffff80200-0xffffc01ff fits inside the range being cleared. Properly setting the level_pfn for the current level under consideration catches that this PTE is outside of the range being cleared. This patch also changes the value passed into dma_pte_free_level() when it recurses. This only affects the first PTE of the range being cleared, and is handled by the existing code that ensures we start our cursor no lower than start_pfn. This was found when using dma_map_sg() to map large chunks of contiguous memory, which immediatedly led to faults on the first access of the erroneously-deleted mappings.

2017-07-05ravb: Fix use-after-free on `ifconfig eth0 down`Eugeniu Rosca
[ Upstream commit 79514ef670e9e575a1fe36922268c439d0f0ca8a ] Commit a47b70ea86bd ("ravb: unmap descriptors when freeing rings") has introduced the issue seen in [1] reproduced on H3ULCB board. Fix this by relocating the RX skb ringbuffer free operation, so that swiotlb page unmapping can be done first. Freeing of aligned TX buffers is not relevant to the issue seen in [1]. Still, reposition TX free calls as well, to have all kfree() operations performed consistently _after_ dma_unmap_*()/dma_free_*().

[ Upstream commit a89af4abdf9b353cdd6f61afc0eaaac403304873 ] Support for the Asus Touchpad was recently added. It turns out this device can fail initialisation (and become unusable) when the RESET command is sent too soon after the POWER ON command. Unfortunately the i2c-hid specification does not specify the need for a delay between these two commands. But it was discovered the Windows driver has a 1ms delay. As a result, this patch modifies the i2c-hid module to add a sleep inbetween the POWER ON and RESET commands which lasts between 1ms and 5ms. See https://github.com/vlasenko/hid-asus-dkms/issues/24 for further details.

[ Upstream commit 23d28a859fb847fd7fcfbd31acb3b160abb5d6ae ] When using the ibmveth driver in a KVM/QEMU based VM, it currently always prints out a scary error message like this when it is started: ibmveth 71000003 (unregistered net_device): unable to change checksum offload settings. 1 rc=-2 ret_attr=71000003 This happens because the driver always tries to enable the checksum offloading without checking for the availability of this feature first. QEMU does not support checksum offloading for the spapr-vlan device, thus we always get the error message here. According to the LoPAPR specification, the "ibm,illan-options" property of the corresponding device tree node should be checked first to see whether the H_ILLAN_ATTRIUBTES hypercall and thus the checksum offloading feature is available. Thus let's do this in the ibmveth driver, too, so that the error message is really only limited to cases where something goes wrong, and does not occur if the feature is just missing.

[ Upstream commit bd00fdf198e2da475a2f4265a83686ab42d998a8 ] The recently added mediated VFIO driver doesn't know about powerpc iommu. It thus doesn't register a struct iommu_table_group in the iommu group upon device creation. The iommu_data pointer hence remains null.

2017-07-05scsi: virtio_scsi: Reject commands when virtqueue is brokenEric Farman
[ Upstream commit 773c7220e22d193e5667c352fcbf8d47eefc817f ] In the case of a graceful set of detaches, where the virtio-scsi-ccw disk is removed from the guest prior to the controller, the guest behaves quite normally. Specifically, the detach gets us into sd_sync_cache to issue a Synchronize Cache(10) command, which immediately fails (and is retried a couple of times) because the device has been removed. Later, the removal of the controller sees two CRWs presented, but there's no further indication of the removal from the guest viewpoint. [ 17.217458] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 17.219257] sd 0:0:0:0: [sda] Synchronize Cache(10) failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK [ 21.449400] crw_info : CRW reports slct=0, oflw=0, chn=1, rsc=3, anc=0, erc=4, rsid=2 [ 21.449406] crw_info : CRW reports slct=0, oflw=0, chn=0, rsc=3, anc=0, erc=4, rsid=0 However, on s390, the SCSI disks can be removed "by surprise" when an entire controller (host) is removed and all associated disks are removed via the loop in scsi_forget_host. The same call to sd_sync_cache is made, but because the controller has already been removed, the Synchronize Cache(10) command is neither issued (and then failed) nor rejected. That the I/O isn't returned means the guest cannot have other devices added nor removed, and other tasks (such as shutdown or reboot) issued by the guest will not complete either. The virtio ring has already been marked as broken (via virtio_break_device in virtio_ccw_remove), but we still attempt to queue the command only to have it remain there. The calling sequence provides a bit of distinction for us: virtscsi_queuecommand() -> virtscsi_kick_cmd() -> virtscsi_add_cmd() -> virtqueue_add_sgs() -> virtqueue_add() if success return 0 elseif vq->broken or vring_mapping_error() return -EIO else return -ENOSPC A return of ENOSPC is generally a temporary condition, so returning "host busy" from virtscsi_queuecommand makes sense here, to have it redriven in a moment or two. But the EIO return code is more of a permanent error and so it would be wise to return the I/O itself and allow the calling thread to finish gracefully. The result is these four kernel messages in the guest (the fourth one does not occur prior to this patch): [ 22.921562] crw_info : CRW reports slct=0, oflw=0, chn=1, rsc=3, anc=0, erc=4, rsid=2 [ 22.921580] crw_info : CRW reports slct=0, oflw=0, chn=0, rsc=3, anc=0, erc=4, rsid=0 [ 22.921978] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 22.921993] sd 0:0:0:0: [sda] Synchronize Cache(10) failed: Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK I opted to fill in the same response data that is returned from the more graceful device detach, where the disk device is removed prior to the controller device.

2017-07-05xen-netfront: Fix Rx stall during network stress and OOMVineeth Remanan Pillai
[ Upstream commit 90c311b0eeead647b708a723dbdde1eda3dcad05 ] During an OOM scenario, request slots could not be created as skb allocation fails. So the netback cannot pass in packets and netfront wrongly assumes that there is no more work to be done and it disables polling. This causes Rx to stall. The issue is with the retry logic which schedules the timer if the created slots are less than NET_RX_SLOTS_MIN. The count of new request slots to be pushed are calculated as a difference between new req_prod and rsp_cons which could be more than the actual slots, if there are unconsumed responses. The fix is to calculate the count of newly created slots as the difference between new req_prod and old req_prod.

2017-07-05swiotlb-xen: update dev_addr after swapping pagesStefano Stabellini
[ Upstream commit f1225ee4c8fcf09afaa199b8b1f0450f38b8cd11 ] In xen_swiotlb_map_page and xen_swiotlb_map_sg_attrs, if the original page is not suitable, we swap it for another page from the swiotlb pool. In these cases, we don't update the previously calculated dma address for the page before calling xen_dma_map_page. Thus, we end up calling xen_dma_map_page passing the wrong dev_addr, resulting in xen_dma_map_page mistakenly assuming that the page is foreign when it is local. Fix the bug by updating dev_addr appropriately. This change has no effect on x86, because xen_dma_map_page is a stub there.

2017-07-05virtio_console: fix a crash in config_work_handlerG. Campana
[ Upstream commit 8379cadf71c3ee8173a1c6fc1ea7762a9638c047 ] Using control_work instead of config_work as the 3rd argument to container_of results in an invalid portdev pointer. Indeed, the work structure is initialized as below: INIT_WORK(&portdev->config_work, &config_work_handler); It leads to a crash when portdev->vdev is dereferenced later. This bug is triggered when the guest uses a virtio-console without multiport feature and receives a config_changed virtio interrupt. Signed-off-by: G.

2017-07-05gianfar: Do not reuse pages from emergency reserveEric Dumazet
[ Upstream commit 69fed99baac186013840ced3524562841296034f ] A driver using dev_alloc_page() must not reuse a page that had to use emergency memory reserve. Otherwise all packets using this page will be immediately dropped, unless for very specific sockets having SOCK_MEMALLOC bit set. This issue might be hard to debug, because only a fraction of the RX ring buffer would suffer from drops.
