* ata-sff: always map page before data transferTycho Andersen2017-05-161-36/+8
| | | | | | | | | | | | | | | | | | | The XPFO [1] patchset may unmap pages from physmap if they happened to be destined for userspace. If such a page is unmapped, it needs to be remapped. Rather than test if a page is in the highmem/xpfo unmapped state, Christoph suggested [2] that we simply always map the page. v2: * drop comment about bounce buffer * don't save IRQs before kmap/unmap * formatting [1]: https://lkml.org/lkml/2016/11/4/245 [2]: https://lkml.org/lkml/2016/11/4/253 Suggested-and-reviewed-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Tycho Andersen <tycho@docker.com> CC: Juerg Haefliger <juerg.haefliger@hpe.com> Signed-off-by: Tejun Heo <tj@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running LDom binding/unbinding test, kernel may panic in ldmvsw_open(). It is more likely that because we're removing the ldc connection before unregistering the netdev in vsw_port_remove(), we set up a window of time where one process could be removing the device while another trying to UP the device. This also sometimes causes vio handshake error due to opening a device without closing it completely. We should unregister the netdev before we disable the "hardware".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Macvlan always turns on offload features that have sofware fallback (NETIF_GSO_SOFTWARE). This allows much higher guest-guest communications over macvtap. However, macvtap does not turn on these features for vlan tagged traffic. As a result, depending on the HW that mactap is configured on, the performance of guest-guest communication over a vlan is very inconsistent. If the HW supports TSO/UFO over vlans, then the performance will be fine. If not, the the performance will suffer greatly since the VM may continue using TSO/UFO, and will force the host segment the traffic and possibly overlow the macvtap queue. This patch adds the always on offloads to vlan_features. This makes sure that any vlan tagged traffic between 2 guest will not be segmented needlessly.

| * vmxnet3: ensure that adapter is in proper state during force_closeNeil Horman2017-05-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several paths in vmxnet3, where settings changes cause the adapter to be brought down and back up (vmxnet3_set_ringparam among them). Should part of the reset operation fail, these paths call vmxnet3_force_close, which enables all napi instances prior to calling dev_close (with the expectation that vmxnet3_close will then properly disable them again). However, vmxnet3_force_close neglects to clear VMXNET3_STATE_BIT_QUIESCED prior to calling dev_close. As a result vmxnet3_quiesce_dev (called from vmxnet3_close), returns early, and leaves all the napi instances in a enabled state while the device itself is closed. If a device in this state is activated again, napi_enable will be called on already enabled napi_instances, leading to a BUG halt. The fix is to simply enausre that the QUIESCED bit is cleared in vmxnet3_force_close to allow quesence to be completed properly on close.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit b4d72c08b358 ("qeth: bridgeport support - basic control") broke the support for OSM and OSN devices as follows: As OSM and OSN are L2 only, qeth_core_probe_device() does an early setup by loading the l2 discipline and calling qeth_l2_probe_device(). In this context, adding the l2-specific bridgeport sysfs attributes via qeth_l2_create_device_attributes() hits a BUG_ON in fs/sysfs/group.c, since the basic sysfs infrastructure for the device hasn't been established yet. Note that OSN actually has its own unique sysfs attributes (qeth_osn_devtype), so the additional attributes shouldn't be created at all. For OSM, add a new qeth_l2_devtype that contains all the common and l2-specific sysfs attributes. When qeth_core_probe_device() does early setup for OSM or OSN, assign the corresponding devtype so that the ccwgroup probe code creates the full set of sysfs attributes. This allows us to skip qeth_l2_create_device_attributes() in case of an early setup. Any device that can't do early setup will initially have only the generic sysfs attributes, and when it's probed later qeth_l2_probe_device() adds the l2-specific attributes. If an early-setup device is removed (by calling ccwgroup_ungroup()), device_unregister() will - using the devtype - delete the l2-specific attributes before qeth_l2_remove_device() is called. So make sure to not remove them twice. What complicates the issue is that qeth_l2_probe_device() and qeth_l2_remove_device() is also called on a device when its layer2 attribute changes (ie. its layer mode is switched). For early-setup devices this wouldn't work properly - we wouldn't remove the l2-specific attributes when switching to L3. But switching the layer mode doesn't actually make any sense; we already decided that the device can only operate in L2! So just refuse to switch the layer mode on such devices. Note that OSN doesn't have a layer2 attribute, so we only need to special-case OSM. Based on an initial patch by Ursula Braun.

| * mdio: mux: Correct mdio_mux_init error path issuesJon Mason2017-05-111-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a potential unnecessary refcount decrement on error path of put_device(&pb->mii_bus->dev), as it is possible to avoid the of_mdio_find_bus() call if mux_bus is specified by the calling function. The same put_device() is not called in the error path if the devm_kzalloc of pb fails. This caused the variable used in the put_device() to be changed, as the pb pointer was obviously not set up. There is an unnecessary of_node_get() on child_bus_node if the of_mdiobus_register() is successful, as the for_each_available_child_of_node() automatically increments this. Thus the refcount on this node will always be +1 more than it should be. There is no of_node_put() on child_bus_node if the of_mdiobus_register() call fails.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently rcode is being initialized to NX_RCODE_SUCCESS and later it is checked to see if it is not NX_RCODE_SUCCESS which is never true.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codes only deal with the case that the skb is dropped, it may meet one use-after-free issue when NF_HOOK returns 0 that means the skb is stolen by one netfilter rule or hook. When one netfilter rule or hook stoles the skb and return NF_STOLEN, it means the skb is taken by the rule, and other modules should not touch this skb ever. Maybe the skb is queued or freed directly by the rule. Now uses the nf_hook instead of NF_HOOK to get the result of netfilter, and check the return value of nf_hook. Only when its value equals 1, it means the skb could go ahead. Or reset the skb as NULL. BTW, because vrf_rcv_finish is empty function, so needn't invoke it even though nf_hook returns 1. But we need to modify vrf_rcv_finish to deal with the NF_STOLEN case. There are two cases when skb is stolen. 1. The skb is stolen and freed directly. There is nothing we need to do, and vrf_rcv_finish isn't invoked. 2. The skb is queued and reinjected again. The vrf_rcv_finish would be invoked as okfn, so need to free the skb in it.

The problem is that ubi_scan_fastmap() moves the fastmap blocks from the scan_ai (allocated in scan_fast()) to the ai allocated in ubi_attach(). This results in two problems: - When the scan_ai is freed, aebs which were allocated from its slab cache are still in use. - When the other ai is being destroyed in destroy_ai(), the arguments to kmem_cache_free() call are incorrect since aebs on its ->fastmap list were allocated with a slab cache from a differnt ai. Fix this by making a copy of the aebs in ubi_scan_fastmap() instead of moving them. ============================================================================= BUG ubi_aeb_slab_cache (Not tainted): Objects remaining in ubi_aeb_slab_cache on __kmem_cache_shutdown() ----------------------------------------------------------------------------- INFO: Slab 0xbfd2da3c objects=17 used=1 fp=0xb33d7748 flags=0x40000080 CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<8026c47c>] (slab_err+0x78/0x88) [<8026c47c>] (slab_err) from [<802735bc>] (__kmem_cache_shutdown+0x180/0x3e0) [<802735bc>] (__kmem_cache_shutdown) from [<8024e13c>] (shutdown_cache+0x1c/0x60) [<8024e13c>] (shutdown_cache) from [<8024ed64>] (kmem_cache_destroy+0x19c/0x20c) [<8024ed64>] (kmem_cache_destroy) from [<8057cc14>] (destroy_ai+0x1dc/0x1e8) [<8057cc14>] (destroy_ai) from [<8057f04c>] (ubi_attach+0x3f4/0x450) [<8057f04c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) INFO: Object 0xb33d7e88 @offset=3720 INFO: Allocated in scan_peb+0x608/0x81c age=72 cpu=1 pid=118 kmem_cache_alloc+0x3b0/0x43c scan_peb+0x608/0x81c ubi_attach+0x124/0x450 ubi_attach_mtd_dev+0x60c/0xff8 ctrl_cdev_ioctl+0x110/0x2b8 do_vfs_ioctl+0xac/0xa00 SyS_ioctl+0x3c/0x64 ret_fast_syscall+0x0/0x1c kmem_cache_destroy ubi_aeb_slab_cache: Slab cache still has objects CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<8024ed80>] (kmem_cache_destroy+0x1b8/0x20c) [<8024ed80>] (kmem_cache_destroy) from [<8057cc14>] (destroy_ai+0x1dc/0x1e8) [<8057cc14>] (destroy_ai) from [<8057f04c>] (ubi_attach+0x3f4/0x450) [<8057f04c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) cache_from_obj: Wrong slab cache. ubi_aeb_slab_cache but object is from ubi_aeb_slab_cache ------------[ cut here ]------------ WARNING: CPU: 1 PID: 118 at mm/slab.h:354 kmem_cache_free+0x39c/0x450 Modules linked in: CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<80120e40>] (__warn+0xf4/0x10c) [<80120e40>] (__warn) from [<80120f20>] (warn_slowpath_null+0x28/0x30) [<80120f20>] (warn_slowpath_null) from [<80271fe0>] (kmem_cache_free+0x39c/0x450) [<80271fe0>] (kmem_cache_free) from [<8057cb88>] (destroy_ai+0x150/0x1e8) [<8057cb88>] (destroy_ai) from [<8057ef1c>] (ubi_attach+0x2c4/0x450) [<8057ef1c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) ---[ end trace 2bd8396277fd0a0b ]--- ============================================================================= BUG ubi_aeb_slab_cache (Tainted: G B W ): page slab pointer corrupt. ----------------------------------------------------------------------------- INFO: Allocated in scan_peb+0x608/0x81c age=104 cpu=1 pid=118 kmem_cache_alloc+0x3b0/0x43c scan_peb+0x608/0x81c ubi_attach+0x124/0x450 ubi_attach_mtd_dev+0x60c/0xff8 ctrl_cdev_ioctl+0x110/0x2b8 do_vfs_ioctl+0xac/0xa00 SyS_ioctl+0x3c/0x64 ret_fast_syscall+0x0/0x1c INFO: Slab 0xbfd2da3c objects=17 used=1 fp=0xb33d7748 flags=0x40000081 INFO: Object 0xb33d7e88 @offset=3720 fp=0xb33d7da0 Redzone b33d7e80: cc cc cc cc cc cc cc cc ........

The size regression is fixed by moving all dax helpers into the dax-core and only specifying "select DAX" for FS_DAX and dax-capable drivers. He also asked for clarification of the NR_DEV_DAX config option which, on closer look, does not need to be a config option at all. Mike also throws in a DEV_DAX_PMEM fixup for good measure. - Ben's attention to detail on -stable patch submissions caught a case where the recent fixes to arch_copy_from_iter_pmem() missed a condition where we strand dirty data in the cache. This is tagged for -stable and will also be included in the rework of the pmem api to a proposed {memcpy,copy_user}_flushcache() interface for 4.13. - Vishal adds a feature that missed the initial pull due to pending review feedback. It allows the kernel to clear media errors when initializing a BTT (atomic sector update driver) instance on a pmem namespace. - Ross noticed that the dax_device + dax_operations conversion broke __dax_zero_page_range(). The nvdimm unit tests fail to check this path, but xfstests immediately trips over it. No excuse for missing this before submitting the 4.12 pull request.

For the flog, instead of doing the smaller log_entry writes only, first do a 'wipe' of the entire area by writing zeroes in large enough chunks so that errors get cleared.
