2017-04-14net: Add a xfrm validate function to validate_xmit_skbSteffen Klassert1-0/+6
When we do IPsec offloading, we need a fallback for packets that were targeted to be IPsec offloaded but rerouted to a device that does not support IPsec offload. For that we add a function that checks the offloading features of the sending device and and flags the requirement of a fallback before it calls the IPsec output function. The IPsec output function adds the IPsec trailer and does encryption if needed. Signed-off-by: Steffen Klassert <[email protected]>
2017-04-14esp6: Reorganize esp_outputSteffen Klassert1-0/+3
We need a fallback for ESP at layer 2, so split esp6_output into generic functions that can be used at layer 3 and layer 2 and use them in esp_output. We also add esp6_xmit which is used for the layer 2 fallback. Signed-off-by: Steffen Klassert <[email protected]>

2017-04-14xfrm: Add an IPsec hardware offloading APISteffen Klassert3-1/+86
This patch adds all the bits that are needed to do IPsec hardware offload for IPsec states and ESP packets. We add xfrmdev_ops to the net_device. xfrmdev_ops has function pointers that are needed to manage the xfrm states in the hardware and to do a per packet offloading decision.

2017-04-13PCI: Add device flag PCI_DEV_FLAGS_BRIDGE_XLATE_ROOTJayachandran C1-0/+2
Add a new quirk flag PCI_DEV_FLAGS_BRIDGE_XLATE_ROOT to limit the DMA alias search to go no further than the bridge where the IOMMU unit is attached. The flag will be used to indicate a bridge device which forwards the address translation requests to the IOMMU, i.e., where the interrupt and DMA requests leave the PCIe hierarchy and go into the system blocks. Usually this happens at the PCI RC, so this flag is not needed. But on systems where there are bridges that introduce aliases above the IOMMU, this flag prevents pci_for_each_dma_alias() from generating aliases that the IOMMU will never see. The function pci_for_each_dma_alias() is updated to stop when it see a bridge with this flag set.

This allows us to not having to acquire the reconfig_mutex for touching the poison list. The add_poison() function has been broken out into two helper functions. One to allocate the poison entry and the other to apppend the entry. This allows us to unlock the poison_lock in non-I/O path and continue to be able to allocate the poison entry with GFP_KERNEL. We will use GFP_NOWAIT in the I/O path in order to satisfy being in atomic context.

This will allow, for example, nl80211 to not send an extra message for cookies identifying newly created objects, but return those directly in the ACK message.

2017-04-12dax: refactor dax-fs into a generic provider of 'struct dax_device' instancesDan Williams1-0/+3
We want dax capable drivers to be able to publish a set of dax operations [1]. However, we do not want to further abuse block_devices to advertise these operations. Instead we will attach these operations to a dax device and add a lookup mechanism to go from block device path to a dax device. A dax capable driver like pmem or brd is responsible for registering a dax device, alongside a block device, and then a dax capable filesystem is responsible for retrieving the dax device by path name if it wants to call dax_operations. For now, we refactor the dax pseudo-fs to be a generic facility, rather than an implementation detail, of the device-dax use case. Where a "dax device" is just an inode + dax infrastructure, and "Device DAX" is a mapping service layered on top of that base 'struct dax_device'. "Filesystem DAX" is then a mapping service that layers a filesystem on top of that same base device. Filesystem DAX is associated with a block_device for now, but perhaps directly to a dax device in the future, or for new pmem-only filesystems.

Pull SCSI target fixes from Nicholas Bellinger: "There has been work in a number of different areas over the last weeks, including: - Fix target-core-user (TCMU) back-end bi-directional handling (Xiubo Li + Mike Christie + Ilias Tsitsimpis) - Fix iscsi-target TMR reference leak during session shutdown (Rob Millner + Chu Yuan Lin) - Fix target_core_fabric_configfs.c race between LUN shutdown + mapped LUN creation (James Shen) - Fix target-core unknown fabric callback queue-full errors (Potnuri Bharat Teja) - Fix iscsi-target + iser-target queue-full handling in order to support iw_cxgb4 RNICs. (Potnuri Bharat Teja + Sagi Grimberg) - Fix ALUA transition state race between multiple initiator (Mike Christie) - Drop work-around for legacy GlobalSAN initiator, to allow QLogic 57840S + 579xx offload HBAs to work out-of-the-box in MSFT environments. (Martin Svec + Arun Easi) Note that a number are CC'ed for stable, and although the queue-full bug-fixes required for iser-target to work with iw_cxgb4 aren't CC'ed here, they'll be posted to Greg-KH separately" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: tcmu: Skip Data-Out blocks before gathering Data-In buffer for BIDI case iscsi-target: Drop work-around for legacy GlobalSAN initiator target: Fix ALUA transition state race between multiple initiators iser-target: avoid posting a recv buffer twice iser-target: Fix queue-full response handling iscsi-target: Propigate queue_data_in + queue_status errors target: Fix unknown fabric callback queue-full errors tcmu: Fix wrongly calculating of the base_command_size tcmu: Fix possible overwrite of t_data_sg's last iov[] target: Avoid mappedlun symlink creation during lun shutdown iscsi-target: Fix TMR reference leak during session shutdown usb: gadget: Correct usb EP argument for BOT status request tcmu: Allow cmd_time_out to be set to zero (disabled)
2017-04-11Merge branch 'for-4.11-fixes' of ↵Linus Torvalds2-0/+25
git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup fixes from Tejun Heo: "This contains fixes for two long standing subtle bugs: - kthread_bind() on a new kthread binds it to specific CPUs and prevents userland from messing with the affinity or cgroup membership. Unfortunately, for cgroup membership, there's a window between kthread creation and kthread_bind*() invocation where the kthread can be moved into a non-root cgroup by userland. Depending on what controllers are in effect, this can assign the kthread unexpected attributes. For example, in the reported case, workqueue workers ended up in a non-root cpuset cgroups and had their CPU affinities overridden. This broke workqueue invariants and led to workqueue stalls. Fixed by closing the window between kthread creation and kthread_bind() as suggested by Oleg. - There was a bug in cgroup mount path which could allow two competing mount attempts to attach the same cgroup_root to two different superblocks. This was caused by mishandling return value from kernfs_pin_sb(). Fixed" * 'for-4.11-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: avoid attaching a cgroup root to two different superblocks cgroup, kthread: close race window where new kthreads can be migrated to non-root cgroups
2017-04-12PM / devfreq: Move struct devfreq_governor to devfreq directoryChanwoo Choi1-29/+1
This patch moves the struct devfreq_governor from header file to the devfreq directory because this structure is private data and it have to be only accessed by the devfreq core. Signed-off-by: Chanwoo Choi <[email protected]> Signed-off-by: MyungJoo Ham <[email protected]>
2017-04-11scsi: sg: disable SET_FORCE_LOW_DMAHannes Reinecke1-1/+0
The ioctl SET_FORCE_LOW_DMA has never worked since the initial git check-in, and the respective setting is nowadays handled correctly. So disable it entirely.

There's one value that use spaces instead of tabs to ident. That causes the following warning: ./include/linux/usb/gadget.h:193: ERROR: Unexpected indentation.

2017-04-11usb: composite.h: fix two warnings when building docsMauro Carvalho Chehab1-2/+3
By definition, we use /* private: */ tag when we won't be documenting a parameter. However, those two parameters are documented: ./include/linux/usb/composite.h:510: warning: Excess struct/union/enum/typedef member 'setup_pending' description in 'usb_composite_dev' ./include/linux/usb/composite.h:510: warning: Excess struct/union/enum/typedef member 'os_desc_pending' description in 'usb_composite_dev' So, we need to use /* public: */ to avoid a warning.
