[PATCH 1/2] xen: fix race in xen_qlock_wait()

by Juergen Gross

In the following situation a vcpu waiting for a lock might not be woken up from xen_poll_irq(): CPU 1: CPU 2: CPU 3: takes a spinlock tries to get lock -> xen_qlock_wait() -> xen_clear_irq_pending() frees the lock -> xen_qlock_kick(cpu2) takes lock again tries to get lock -> *lock = _Q_SLOW_VAL -> *lock == _Q_SLOW_VAL ? -> xen_poll_irq() frees the lock -> xen_qlock_kick(cpu3) And cpu 2 will sleep forever. This can be avoided easily by modifying xen_qlock_wait() to call xen_poll_irq() only if the related irq was not pending and to call xen_clear_irq_pending() only if it was pending.

[PATCH stable v4.17] PCI: aardvark: Size bridges before resources allocation

by Thomas Petazzoni

From: Zachary Zhang <zhangzg(a)marvell.com> commit 91a2968e245d6ba616db37001fa1a043078b1a65 usptream. The PCIE I/O and MEM resource allocation mechanism is that root bus goes through the following steps: 1. Check PCI bridges' range and computes I/O and Mem base/limits. 2. Sort all subordinate devices I/O and MEM resource requirements and allocate the resources and writes/updates subordinate devices' requirements to PCI bridges I/O and Mem MEM/limits registers. Currently, PCI Aardvark driver only handles the second step and lacks the first step, so there is an I/O and MEM resource allocation failure when using a PCI switch. This commit fixes that by sizing bridges before doing the resource allocation.

[PATCH AUTOSEL 3.18 01/13] usb: gadget: fotg210-udc: Fix memory leak of fotg210->ep[i]

by Sasha Levin

From: Anton Vasilyev <vasilyev(a)ispras.ru> [ Upstream commit c37bd52836296ecc9a0fc8060b819089aebdbcde ] There is no deallocation of fotg210->ep[i] elements, allocated at fotg210_udc_probe. The patch adds deallocation of fotg210->ep array elements and simplifies error path of fotg210_udc_probe(). Found by Linux Driver Verification project (linuxtesting.org).

[PATCH AUTOSEL 4.14 01/37] netfilter: xt_cluster: add dependency on conntrack module

by Sasha Levin

From: Martin Willi <martin(a)strongswan.org> [ Upstream commit c1dc2912059901f97345d9e10c96b841215fdc0f ] The cluster match requires conntrack for matching packets. If the netns does not have conntrack hooks registered, the match does not work at all. Implicitly load the conntrack hook for the family, exactly as many other extensions do. This ensures that the match works even if the hooks have not been registered by other means.
