2017-04-01cdc-acm: log message for serial state notificationTobias Herzog
Adds a similar log message to USB_CDC_NOTIFY_SERIAL_STATE as it is already done with USB_CDC_NOTIFY_NETWORK_CONNECTION. Signed-off-by: Tobias Herzog <t-herzog@gmx.de> Acked-by: Oliver Neukum <oneukum@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-01cdc-acm: reassemble fragmented notificationsTobias Herzog
USB devices may have very limited endpoint packet sizes, so that notifications can not be transferred within one single usb packet. Reassembling of multiple packages may be necessary.

2017-04-01cdc-acm: fix possible invalid access when processing notificationTobias Herzog
Notifications may only be 8 bytes long. Accessing the 9th and 10th byte of unimplemented/unknown notifications may be insecure. Also check the length of known notifications before accessing anything behind the 8th byte.

2017-03-29USB: Proper handling of Race Condition when two USB class drivers try to ↵Ajay Kaher
call init_usb_class simultaneously There is race condition when two USB class drivers try to call init_usb_class at the same time and leads to crash. code path: probe->usb_register_dev->init_usb_class To solve this, mutex locking has been added in init_usb_class() and destroy_usb_class(). As pointed by Alan, removed "if (usb_class)" test from destroy_usb_class() because usb_class can never be NULL there.

2017-03-29USB: lvstest: tighten endpoint sanity checkJohan Hovold
Use the new endpoint helpers to lookup the required interrupt-in endpoint.

2017-03-24RDMA/iser: Fix possible mr leak on device removal eventSagi Grimberg
When the rdma device is removed, we must cleanup all the rdma resources within the DEVICE_REMOVAL event handler to let the device teardown gracefully. When this happens with live I/O, some memory regions are occupied. Thus, track them too and dereg all the mr's. We are safe with mr access by iscsi_iser_cleanup_task.

2017-03-24IB/device: Convert ib-comp-wq to be CPU-boundSagi Grimberg
This workqueue is used by our storage target mode ULPs via the new CQ API. Recent observations when working with very high-end flash storage devices reveal that UNBOUND workqueue threads can migrate between cpu cores and even numa nodes (although some numa locality is accounted for). While this attribute can be useful in some workloads, it does not fit in very nicely with the normal run-to-completion model we usually use in our target-mode ULPs and the block-mq irq<->cpu affinity facilities. The whole block-mq concept is that the completion will land on the same cpu where the submission was performed. The fact that our submitter thread is migrating cpus can break this locality. We assume that as a target mode ULP, we will serve multiple initiators/clients and we can spread the load enough without having to use unbound kworkers. Also, while we're at it, expose this workqueue via sysfs which is harmless and can be useful for debug.

2017-03-24IB/rxe: increment msn only when completing a requestDavid Marchand
According to C9-147, MSN should only be incremented when the last packet of a multi packet request has been received. "Logically, the requester associates a sequential Send Sequence Number (SSN) with each WQE posted to the send queue. The SSN bears a one- to-one relationship to the MSN returned by the responder in each re- sponse packet. Therefore, when the requester receives a response, it in- terprets the MSN as representing the SSN of the most recent request completed by the responder to determine which send WQE(s) can be completed."

2017-03-24infiniband: Fix alignment of mmap cookies to support VIPT cachingJason Gunthorpe
When vmalloc_user is used to create memory that is supposed to be mmap'd to user space, it is necessary for the mmap cookie (eg the offset) to be aligned to SHMLBA. This creates a situation where all virtual mappings of the same physical page share the same virtual cache index and guarantees VIPT coherence. Otherwise the cache is non-coherent and the kernel will not see writes by userspace when reading the shared page (or vice-versa).

2017-03-24i40iw: Receive netdev events post INET_NOTIFIER stateShiraz Saleem
Netdev notification events are de-registered only when all client iwdev instances are removed. If a single client is closed and re-opened, netdev events could arrive even before the Control Queue-Pair (CQP) is created, causing a NULL pointer dereference crash in i40iw_get_cqp_request. Fix this by allowing netdev event notification only after we have reached the INET_NOTIFIER state with respect to device initialization.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management fixes from Rafael Wysocki: "One of these is an intel_pstate regression fix and it is not a small change, but it mostly removes code that shouldn't be there. That code was acquired by mistake and has been a source of constant pain since then, so the time has come to get rid of it finally. We have not seen problems with this change in the lab, so fingers crossed. The rest is more usual: one more intel_pstate commit removing useless code, a cpufreq core fix to make it restore policy limits on CPU online (which prevents the limits from being reset over system suspend/resume), a schedutil cpufreq governor initialization fix to make it actually work as advertised on all systems and an extra sanity check in the cpuidle core to prevent crashes from happening if the arch code messes things up. Specifics: - Make intel_pstate use one set of global P-state limits in the active mode regardless of the scaling_governor settings for individual CPUs instead of switching back and forth between two of them in a way that is hard to control (Rafael Wysocki). - Drop a useless function from intel_pstate to prevent it from modifying the maximum supported frequency value unexpectedly which may confuse the cpufreq core (Rafael Wysocki). - Fix the cpufreq core to restore policy limits on CPU online so that the limits are not reset over system suspend/resume, among other things (Viresh Kumar). - Fix the initialization of the schedutil cpufreq governor to make the IO-wait boosting mechanism in it actually work on systems with one CPU per cpufreq policy (Rafael Wysocki). - Add a sanity check to the cpuidle core to prevent crashes from happening if the architecture code initialization fails to set up things as expected (Vaidyanathan Srinivasan)" * tag 'pm-4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq: Restore policy min/max limits on CPU online cpuidle: Validate cpu_dev in cpuidle_add_sysfs() cpufreq: intel_pstate: Fix policy data management in passive mode cpufreq: schedutil: Fix per-CPU structure initialization in sugov_start() cpufreq: intel_pstate: One set of global limits in active mode

This has been around for a long time but it's finally fixed. f_hid learned that it should never access hidg->req without first grabbing the spinlock. Roger Quadros fixed two bugs in the f_uvc function driver. Janusz Dziedzic fixed a very peculiar bug with EP0, one that's rather difficult to trigger. When we're dealing with bounced EP0 requests, we should delay unmap until after ->complete() is called. UDC class got a use-after-free fix.
