2016-06-23of: iommu: make of_iommu_init() postcore_initcall_syncKefeng Wang1-2/+0
The of_iommu_init() is called multiple times by arch code, make it postcore_initcall_sync, then we can drop relevant calls fully. Note, the IOMMUs should have a chance to perform some basic initialisation before we start adding masters to them. So postcore_initcall_sync is good choice, it ensures of_iommu_init() called before of_platform_populate.

2016-06-23pwm: Fix pwm_apply_args()Boris Brezillon1-6/+10
Commit 5ec803edcb70 ("pwm: Add core infrastructure to allow atomic updates"), implemented pwm_disable() as a wrapper around pwm_apply_state(), and then, commit ef2bf4997f7d ("pwm: Improve args checking in pwm_apply_state()") added missing checks on the ->period value in pwm_apply_state() to ensure we were not passing inappropriate values to the ->config() or ->apply() methods. The conjunction of these 2 commits led to a case where pwm_disable() was no longer succeeding, thus preventing the polarity setting done in pwm_apply_args(). Set a valid period in pwm_apply_args() to ensure polarity setting won't be rejected.

2016-06-23IB/core: Add get FW version string to the coreIra Weiny1-0/+3
Allow for a common core function to get firmware version strings from the individual devices. In later patches this format can then then be used to pass a properly formated version string through the IPoIB layer. The problem with the current code in the IPoIB layer is that it is specific to certain hardware types. Furthermore, this gives us a common function through which the core can provide a common sysfs entry. Eventually we may want to remove the sysfs export but this provides for user space backwards compatibility.

Alexey reported that we have GFP_KERNEL allocation when holding the spinlock tcf_lock. Actually we don't have to take that spinlock for all the cases, especially for the new one we just create. To modify the existing actions, we still need this spinlock to make sure the whole update is atomic. For net-next, we can get rid of this spinlock because we already hold the RTNL lock on slow path, and on fast path we can use RCU to protect the metalist. Joint work with Jamal.

2016-06-23IB/mlx5: Reset flow support for IB kernel ULPsMaor Gottlieb1-0/+2
The driver exposes interfaces that directly relate to HW state. Upon fatal error, consumers of these interfaces (ULPs) that rely on completion of all their posted work-request could hang, thereby introducing dependencies in shutdown order. To prevent this from happening, we manage the relevant resources (CQs, QPs) that are used by the device. Upon a fatal error, we now generate simulated completions for outstanding WQEs that were not completed at the time the HW was reset. It includes invoking the completion event handler for all involved CQs so that the ULPs will poll those CQs. When polled we return simulated CQEs with IB_WC_WR_FLUSH_ERR return code enabling ULPs to clean up their resources and not wait forever for completions upon receiving remove_one. The above change requires an extra check in the data path to make sure that when device is in error state, the simulated CQEs will be returned and no further WQEs will be posted.

2016-06-23IB/core: Introduce Work Queue object and its verbsYishai Hadas1-1/+55
Introduce Work Queue object and its create/destroy/modify verbs. QP can be created without internal WQs "packaged" inside it, this QP can be configured to use "external" WQ object as its receive/send queue. WQ is a necessary component for RSS technology since RSS mechanism is supposed to distribute the traffic between multiple Receive Work Queues. WQ associated (many to one) with Completion Queue and it owns WQ properties (PD, WQ size, etc.). WQ has a type, this patch introduces the IB_WQT_RQ (i.e.receive queue), it may be extend to others such as IB_WQT_SQ. (send queue). WQ from type IB_WQT_RQ contains receive work requests. PD is an attribute of a work queue (i.e. send/receive queue), it's used by the hardware for security validation before scattering to a memory region which is pointed by the WQ. For that, an external WQ object needs a PD, letting the hardware makes that validation. When accessing a memory region that is pointed by the WQ its PD is used and not the QP's PD, this behavior is similar to a SRQ and a QP. WQ context is subject to a well-defined state transitions done by the modify_wq verb. When WQ is created its initial state becomes IB_WQS_RESET. >From IB_WQS_RESET it can be modified to itself or to IB_WQS_RDY. >From IB_WQS_RDY it can be modified to itself, to IB_WQS_RESET or to IB_WQS_ERR. >From IB_WQS_ERR it can be modified to IB_WQS_RESET. Note: transition to IB_WQS_ERR might occur implicitly in case there was some HW error.

The commit f2a4d086ed4c ("openvswitch: Add packet truncation support.") introduces packet truncation before sending to userspace upcall receiver. This patch passes up the skb->len before truncation so that the upcall receiver knows the original packet size. Potentially this will be used by sFlow, where OVS translates sFlow config header=N to a sample action, truncating packet to N byte in kernel datapath. Thus, only N bytes instead of full-packet size is copied from kernel to userspace, saving the kernel-to-userspace bandwidth.

2016-06-22rxrpc: Fix exclusive connection handlingDavid Howells1-1/+2
"Exclusive connections" are meant to be used for a single client call and then scrapped. The idea is to limit the use of the negotiated security context. The current code, however, isn't doing this: it is instead restricting the socket to a single virtual connection and doing all the calls over that. This is changed such that the socket no longer maintains a special virtual connection over which it will do all the calls, but rather gets a new one each time a new exclusive call is made. Further, using a socket option for this is a poor choice. It should be done on sendmsg with a control message marker instead so that calls can be marked exclusive individually. To that end, add RXRPC_EXCLUSIVE_CALL which, if passed to sendmsg() as a control message element, will cause the call to be done on an single-use connection. The socket option (RXRPC_EXCLUSIVE_CONNECTION) still exists and, if set, will override any lack of RXRPC_EXCLUSIVE_CALL being specified so that programs using the setsockopt() will appear to work the same.

2016-06-21drm: Extract drm_is_current_masterDaniel Vetter1-6/+7
Just rolling out a bit of abstraction to be able to clean up the master logic in the next step.

2016-06-21drm: Refactor drop/set master code a bitDaniel Vetter1-2/+1
File open/set_maseter ioctl and file close/drop_master ioctl share the same master handling code. Extract it. Note that vmwgfx's master_set callback needs to know whether the master is a new one or has been used already, so thread this through. On the close/drop side a similar parameter existed, but wasnt used. Drop it to simplify the flow. v2: Try to make it not leak so much (Emil). v3: Send out the right version ...

2016-06-21drm: Lobotomize set_busid nonsense for !pci driversDaniel Vetter1-1/+0
We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

2016-06-21drm: Don't call drm_dev_set_unique from platform driversDaniel Vetter1-1/+0
Since commit e112e593b215c394c0303dbf0534db0928e87967 Author: Nicolas Iooss <nicolas.iooss_linux@m4x.org> Date: Fri Dec 11 11:20:28 2015 +0100 drm: use dev_name as default unique name in drm_dev_alloc() we're using a reasonable default which should work for everyone. Only mtk, rcar-du and sun4i are affected, and as kms-only drivers without any rendering support no one should ever care about the unique name v2: Rebase on top of mediatek.
