usb: usbip: set buffer pointers to NULL after free

2017-07-12T14:55:23Z

commit b3b51417d0af63fb9a06662dc292200aed9ea53f upstream. The usbip stack dynamically allocates the transfer_buffer and setup_packet of each urb that got generated by the tcp to usb stub code. As these pointers are always used only once we will set them to NULL after use. This is done likewise to the free_urb code in vudc_dev.c. This patch fixes double kfree situations where the usbip remote side added the URB_FREE_BUFFER. Signed-off-by: Michael Grzeschik Acked-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

USB: usbip: fix nonconforming hub descriptor

2017-05-17T09:53:02Z

Fix up the root-hub descriptor to accommodate the variable-length DeviceRemovable and PortPwrCtrlMask fields, while marking all ports as removable (and leaving the reserved bit zero unset). Also add a build-time constraint on VHCI_HC_PORTS which must never be greater than USB_MAXCHILDREN (but this was only enforced through a KConfig constant). This specifically fixes the descriptor layout whenever VHCI_HC_PORTS is greater than seven (default is 8).

vhci_tx_urb() should be able to get the vhci_device from its caller vhci_urb_enqueue(), instead of brutal-force searching it. Reviewed-by: Krzysztof Opasiak Signed-off-by: Yuyang Du Acked-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

Pull sched.h split-up from Ingo Molnar: "The point of these changes is to significantly reduce the header footprint, to speed up the kernel build and to have a cleaner header structure. After these changes the new 's typical preprocessed size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K lines), which is around 40% faster to build on typical configs. Not much changed from the last version (-v2) posted three weeks ago: I eliminated quirks, backmerged fixes plus I rebased it to an upstream SHA1 from yesterday that includes most changes queued up in -next plus all sched.h changes that were pending from Andrew. I've re-tested the series both on x86 and on cross-arch defconfigs, and did a bisectability test at a number of random points. I tried to test as many build configurations as possible, but some build breakage is probably still left - but it should be mostly limited to architectures that have no cross-compiler binaries available on kernel.org, and non-default configurations" * 'WIP.sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (146 commits) sched/headers: Clean up sched/headers: Remove #ifdefs from sched/headers: Remove the include from sched/headers, hrtimer: Remove the include from sched/headers, x86/apic: Remove the header inclusion from sched/headers, timers: Remove the include from sched/headers: Remove from sched/headers: Remove from sched/core: Remove unused prefetch_stack() sched/headers: Remove from sched/headers: Remove the 'init_pid_ns' prototype from sched/headers: Remove from sched/headers: Remove from sched/headers: Remove the runqueue_is_locked() prototype sched/headers: Remove from sched/headers: Remove from sched/headers: Remove from sched/headers: Remove from sched/headers: Remove the include from sched/headers: Remove from ...
