2015-09-10net: ipv6: use common fib_default_rule_prefPhil Sutter7-19/+3
This switches IPv6 policy routing to use the shared fib_default_rule_pref() function of IPv4 and DECnet. It is also used in multicast routing for IPv4 as well as IPv6. The motivation for this patch is a complaint about iproute2 behaving inconsistent between IPv4 and IPv6 when adding policy rules: Formerly, IPv6 rules were assigned a fixed priority of 0x3FFF whereas for IPv4 the assigned priority value was decreased with each rule added. Since then all users of the default_pref field have been converted to assign the generic function fib_default_rule_pref(), fib_nl_newrule() may just use it directly instead. Therefore get rid of the function pointer altogether and make fib_default_rule_pref() static, as it's not used outside fib_rules.c anymore.

2015-09-10ipv6: fix multipath route replace error recoveryRoopa Prabhu1-26/+175
Problem: The ecmp route replace support for ipv6 in the kernel, deletes the existing ecmp route too early, ie when it installs the first nexthop. If there is an error in installing the subsequent nexthops, its too late to recover the already deleted existing route leaving the fib in an inconsistent state. This patch reduces the possibility of this by doing the following: a) Changes the existing multipath route add code to a two stage process: build rt6_infos + insert them ip6_route_add rt6_info creation code is moved into ip6_route_info_create. b) This ensures that most errors are caught during building rt6_infos and we fail early c) Separates multipath add and del code. Because add needs the special two stage mode in a) and delete essentially does not care. d) In any event if the code fails during inserting a route again, a warning is printed (This should be unlikely) Before the patch: $ip -6 route show 3000:1000:1000:1000::2 via fe80::202:ff:fe00:b dev swp49s0 metric 1024 3000:1000:1000:1000::2 via fe80::202:ff:fe00:d dev swp49s1 metric 1024 3000:1000:1000:1000::2 via fe80::202:ff:fe00:f dev swp49s2 metric 1024 /* Try replacing the route with a duplicate nexthop */ $ip -6 route change 3000:1000:1000:1000::2/128 nexthop via fe80::202:ff:fe00:b dev swp49s0 nexthop via fe80::202:ff:fe00:d dev swp49s1 nexthop via fe80::202:ff:fe00:d dev swp49s1 RTNETLINK answers: File exists $ip -6 route show /* previously added ecmp route 3000:1000:1000:1000::2 dissappears from * kernel */ After the patch: $ip -6 route show 3000:1000:1000:1000::2 via fe80::202:ff:fe00:b dev swp49s0 metric 1024 3000:1000:1000:1000::2 via fe80::202:ff:fe00:d dev swp49s1 metric 1024 3000:1000:1000:1000::2 via fe80::202:ff:fe00:f dev swp49s2 metric 1024 /* Try replacing the route with a duplicate nexthop */ $ip -6 route change 3000:1000:1000:1000::2/128 nexthop via fe80::202:ff:fe00:b dev swp49s0 nexthop via fe80::202:ff:fe00:d dev swp49s1 nexthop via fe80::202:ff:fe00:d dev swp49s1 RTNETLINK answers: File exists $ip -6 route show 3000:1000:1000:1000::2 via fe80::202:ff:fe00:b dev swp49s0 metric 1024 3000:1000:1000:1000::2 via fe80::202:ff:fe00:d dev swp49s1 metric 1024 3000:1000:1000:1000::2 via fe80::202:ff:fe00:f dev swp49s2 metric 1024 Fixes: 27596472473a ("ipv6: fix ECMP route replacement") Signed-off-by: Roopa Prabhu <roopa@cumulusnetworks.com> Reviewed-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

2015-09-09ebpf: fix fd refcount leaks related to maps in bpf syscallDaniel Borkmann1-4/+8
We may already have gotten a proper fd struct through fdget(), so whenever we return at the end of an map operation, we need to call fdput(). However, each map operation from syscall side first probes CHECK_ATTR() to verify that unused fields in the bpf_attr union are zero. In case of malformed input, we return with error, but the lookup to the map_fd was already performed at that time, so that we return without an corresponding fdput(). Fix it by performing an fdget() only right before bpf_map_get(). The fdget() invocation on maps in the verifier is not affected.

2015-09-09xen-netback: require fewer guest Rx slots when not using GSODavid Vrabel2-17/+16
Commit f48da8b14d04ca87ffcffe68829afd45f926ec6a (xen-netback: fix unlimited guest Rx internal queue and carrier flapping) introduced a regression. The PV frontend in IPXE only places 4 requests on the guest Rx ring. Since netback required at least (MAX_SKB_FRAGS + 1) slots, IPXE could not receive any packets. a) If GSO is not enabled on the VIF, fewer guest Rx slots are required for the largest possible packet. Calculate the required slots based on the maximum GSO size or the MTU. This calculation of the number of required slots relies on 1650d5455bd2 (xen-netback: always fully coalesce guest Rx packets) which present in 4.0-rc1 and later. b) Reduce the Rx stall detection to checking for at least one available Rx request.

2015-09-09dax: update PMD fault handler with PMEM APIRoss Zwisler1-2/+4
As part of the v4.3 merge window the DAX code was updated by Matthew and Kirill to handle PMD pages. Also as part of the v4.3 merge window we updated the DAX code to do proper PMEM flushing (commit 2765cfbb342c: "dax: update I/O path to do proper PMEM flushing"). The additional code added by the DAX PMD patches also needs to be updated to properly use the PMEM API. This ensures that after a PMD fault is handled the zeros written to the newly allocated pages are durable on the DIMMs. linux/dax.h is included to get rid of a bunch of sparse warnings.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull inifiniband/rdma updates from Doug Ledford: "This is a fairly sizeable set of changes. I've put them through a decent amount of testing prior to sending the pull request due to that. There are still a few fixups that I know are coming, but I wanted to go ahead and get the big, sizable chunk into your hands sooner rather than waiting for those last few fixups. Of note is the fact that this creates what is intended to be a temporary area in the drivers/staging tree specifically for some cleanups and additions that are coming for the RDMA stack. We deprecated two drivers (ipath and amso1100) and are waiting to hear back if we can deprecate another one (ehca). We also put Intel's new hfi1 driver into this area because it needs to be refactored and a transfer library created out of the factored out code, and then it and the qib driver and the soft-roce driver should all be modified to use that library. I expect drivers/staging/rdma to be around for three or four kernel releases and then to go away as all of the work is completed and final deletions of deprecated drivers are done. Summary of changes for 4.3: - Create drivers/staging/rdma - Move amso1100 driver to staging/rdma and schedule for deletion - Move ipath driver to staging/rdma and schedule for deletion - Add hfi1 driver to staging/rdma and set TODO for move to regular tree - Initial support for namespaces to be used on RDMA devices - Add RoCE GID table handling to the RDMA core caching code - Infrastructure to support handling of devices with differing read and write scatter gather capabilities - Various iSER updates - Kill off unsafe usage of global mr registrations - Update SRP driver - Misc mlx4 driver updates - Support for the mr_alloc verb - Support for a netlink interface between kernel and user space cache daemon to speed path record queries and route resolution - Ininitial support for safe hot removal of verbs devices" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (136 commits) IB/ipoib: Suppress warning for send only join failures IB/ipoib: Clean up send-only multicast joins IB/srp: Fix possible protection fault IB/core: Move SM class defines from ib_mad.h to ib_smi.h IB/core: Remove unnecessary defines from ib_mad.h IB/hfi1: Add PSM2 user space header to header_install IB/hfi1: Add CSRs for CONFIG_SDMA_VERBOSITY mlx5: Fix incorrect wc pkey_index assignment for GSI messages IB/mlx5: avoid destroying a NULL mr in reg_user_mr error flow IB/uverbs: reject invalid or unknown opcodes IB/cxgb4: Fix if statement in pick_local_ip6adddrs IB/sa: Fix rdma netlink message flags IB/ucma: HW Device hot-removal support IB/mlx4_ib: Disassociate support IB/uverbs: Enable device removal when there are active user space applications IB/uverbs: Explicitly pass ib_dev to uverbs commands IB/uverbs: Fix race between ib_uverbs_open and remove_one IB/uverbs: Fix reference counting usage of event files IB/core: Make ib_dealloc_pd return void IB/srp: Create an insecure all physical rkey only if needed ...

This commit adds support for NXP LPC18xx PWM/SCT. NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State Configurable Timer (SCT) which can be configured as a Pulse Width Modulator. Other SoCs in that family may share the same hardware. The PWM supports a total of 16 channels, but only 15 can be simultaneously requested. There's only one period, global to all the channels, thus PWM driver will refuse setting different values to it, unless there's only one channel requested.
