2015-05-06KVM: s390: fix get_all_floating_irqsJens Freimann
commit 94aa033efcac47b09db22cb561e135baf37b7887 upstream. This fixes a bug introduced with commit c05c4186bbe4 ("KVM: s390: add floating irq controller"). get_all_floating_irqs() does copy_to_user() while holding a spin lock. Let's fix this by filling a temporary buffer first and copy it to userspace after giving up the lock.

2015-05-06net: rfs: fix crash in get_rps_cpus()Eric Dumazet
[ Upstream commit a31196b07f8034eba6a3487a1ad1bb5ec5cd58a5 ] Commit 567e4b79731c ("net: rfs: add hash collision detection") had one mistake : RPS_NO_CPU is no longer the marker for invalid cpu in set_rps_cpu() and get_rps_cpu(), as @next_cpu was the result of an AND with rps_cpu_mask This bug showed up on a host with 72 cpus : next_cpu was 0x7f, and the code was trying to access percpu data of an non existent cpu. In a follow up patch, we might get rid of compares against nr_cpu_ids, if we init the tables with 0. This is silly to test for a very unlikely condition that exists only shortly after table initialization, as we got rid of rps_reset_sock_flow() and similar functions that were writing this RPS_NO_CPU magic value at flow dismantle : When table is old enough, it never contains this value anymore.

Pull networking fixes from David Miller: 1) In TCP, don't register an FRTO for cumulatively ACK'd data that was previously SACK'd, from Neal Cardwell. 2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup, from Cong WANG. 3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also from Cong WANG. 4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel. 5) When we encapsulate for a tunnel device, skb->sk still points to the user socket. So this leads to cases where we retraverse the ipv4/ipv6 output path with skb->sk being of some other address family (f.e. AF_PACKET). This can cause things to crash since the ipv4 output path is dereferencing an AF_PACKET socket as if it were an ipv4 one. The short term fix for 'net' and -stable is to elide these socket checks once we've entered an encapsulation sequence by testing xmit_recursion. Longer term we have a better solution wherein we pass the tunnel's socket down through the output paths, but that is way too invasive for 'net' and -stable. From Hannes Frederic Sowa. 6) l2tp_init() failure path forgets to unregister per-net ops, from Cong WANG. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net/mlx4_core: Fix error message deprecation for ConnectX-2 cards net: dsa: fix filling routing table from OF description l2tp: unregister l2tp_net_ops on failure path mvneta: dont call mvneta_adjust_link() manually ipv6: protect skb->sk accesses from recursive dereference inside the stack netns: don't allocate an id for dead netns Revert "netns: don't clear nsid too early on removal" ip6mr: call del_timer_sync() in ip6mr_free_table() net: move fib_rules_unregister() under rtnl lock ipv4: take rtnl_lock and mark mrt table as freed on namespace cleanup tcp: fix FRTO undo on cumulative ACK of SACKed range xen-netfront: transmit fully GSO-sized packets
2015-04-06net: dsa: fix filling routing table from OF descriptionPavel Nakonechny
According to description in 'include/net/dsa.h', in cascade switches configurations where there are more than one interconnected devices, 'rtable' array in 'dsa_chip_data' structure is used to indicate which port on this switch should be used to send packets to that are destined for corresponding switch. However, dsa_of_setup_routing_table() fills 'rtable' with port numbers of the _target_ switch, but not current one. This commit removes redundant devicetree parsing and adds needed port number as a function argument. So dsa_of_setup_routing_table() now just looks for target switch number by parsing parent of 'link' device node. To remove possible misunderstandings with the way of determining target switch number, a corresponding comment was added to the source code and to the DSA device tree bindings documentation file. This was tested on a custom board with two Marvell 88E6095 switches with following corresponding routing tables: { -1, 10 } and { 8, -1 }.

2015-03-20Input: add MT_TOOL_PALMCharlie Mooney
Currently there are only two "tools" that can be specified by a multi-touch driver: MT_TOOL_FINGER and MT_TOOL_PEN. In working with Elan (The touch vendor) and discussing their next-gen devices it seems that it will be useful to have more tools so that their devices can give the upper layers of the stack hints as to what is touching the sensor. In particular they have new experimental firmware that can better differentiate between palms vs fingertips and would like to plumb a patch so that we can use their hints in higher-level gesture soft- ware. The firmware on the device can reasonably do a better job of palm detection because it has access to all of the raw sensor readings as opposed to just the width/pressure/etc that are exposed by the driver. As such, the firmware can characterize what a palm looks like in much finer-grained detail and this change would allow such a device to share its findings with the kernel.

Allows one to force Data Carrier Detect, Clear To Send, and Data Set Ready signals to permanently be reported as active. The Ring indicator can be forced to be reported as inactive. It is possible that if modem control signalling is enabled on a port that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the driver can hang indefinitely waiting for the state to change. The new DT properties allow the driver to ignore the state of these pins on serial ports that don't support them, as recommended in the kernel documentation.

Specifics: - Fix ACPI resources management problems introduced by the recent rework of the code in question (Jiang Liu) and a build issue introduced by those changes (Joachim Nilsson). - Fix a recent suspend-to-idle regression on systems where entering idle states causes local timers to stop, prevent suspend-to-idle from crashing in restricted configurations (no cpuidle driver, cpuidle disabled etc.) and clean up the idle loop somewhat while at it (Rafael J Wysocki). - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven). - Allow the ACPI backlight driver module to be loaded if ACPI is disabled which helps the i915 driver in those configurations (stable-candidate) and change the code to help debug unusual use cases (Chris Wilson). - Wakeup IRQ management changes in v3.18 caused some drivers on the at91 platform to trigger a warning from the IRQ core related to an unexpected combination of interrupt action handler flags.

2015-02-26genirq / PM: better describe IRQF_NO_SUSPEND semanticsMark Rutland
The IRQF_NO_SUSPEND flag is intended to be used for interrupts required to be enabled during the suspend-resume cycle. This mostly consists of IPIs and timer interrupts, potentially including chained irqchip interrupts if these are necessary to handle timers or IPIs. If an interrupt does not fall into one of the aforementioned categories, requesting it with IRQF_NO_SUSPEND is likely incorrect. Using IRQF_NO_SUSPEND does not guarantee that the interrupt can wake the system from a suspended state. For an interrupt to be able to trigger a wakeup, it may be necessary to program various components of the system. In these cases it is necessary to use {enable,disabled}_irq_wake. Unfortunately, several drivers assume that IRQF_NO_SUSPEND ensures that an IRQ can wake up the system, and the documentation can be read ambiguously w.r.t. this property. This patch updates the documentation regarding IRQF_NO_SUSPEND to make this caveat explicit, hopefully making future misuse rarer. Cleanup of existing misuse will occur as part of later patch series.
