Pull networking updates from David Miller: Changes of note: 1) Allow to schedule ICMP packets in IPVS, from Alex Gartrell. 2) Provide FIB table ID in ipv4 route dumps just as ipv6 does, from David Ahern. 3) Allow the user to ask for the statistics to be filtered out of ipv4/ipv6 address netlink dumps. From Sowmini Varadhan. 4) More work to pass the network namespace context around deep into various packet path APIs, starting with the netfilter hooks. From Eric W Biederman. 5) Add layer 2 TX/RX checksum offloading to qeth driver, from Thomas Richter. 6) Use usec resolution for SYN/ACK RTTs in TCP, from Yuchung Cheng. 7) Support Very High Throughput in wireless MESH code, from Bob Copeland. 8) Allow setting the ageing_time in switchdev/rocker. From Scott Feldman. 9) Properly autoload L2TP type modules, from Stephen Hemminger. 10) Fix and enable offload features by default in 8139cp driver, from David Woodhouse. 11) Support both ipv4 and ipv6 sockets in a single vxlan device, from Jiri Benc. 12) Fix CWND limiting of thin streams in TCP, from Bendik Rønning Opstad. 13) Fix IPSEC flowcache overflows on large systems, from Steffen Klassert. 14) Convert bridging to track VLANs using rhashtable entries rather than a bitmap. From Nikolay Aleksandrov. 15) Make TCP listener handling completely lockless, this is a major accomplishment. Incoming request sockets now live in the established hash table just like any other socket too. From Eric Dumazet. 15) Provide more bridging attributes to netlink, from Nikolay Aleksandrov. 16) Use hash based algorithm for ipv4 multipath routing, this was very long overdue. From Peter Nørlund. 17) Several y2038 cures, mostly avoiding timespec. From Arnd Bergmann. 18) Allow non-root execution of EBPF programs, from Alexei Starovoitov. 19) Support SO_INCOMING_CPU as setsockopt, from Eric Dumazet. This influences the port binding selection logic used by SO_REUSEPORT. 20) Add ipv6 support to VRF, from David Ahern. 21) Add support for Mellanox Spectrum switch ASIC, from Jiri Pirko. 22) Add rtl8xxxu Realtek wireless driver, from Jes Sorensen. 23) Implement RACK loss recovery in TCP, from Yuchung Cheng. 24) Support multipath routes in MPLS, from Roopa Prabhu. 25) Fix POLLOUT notification for listening sockets in AF_UNIX, from Eric Dumazet. 26) Add new QED Qlogic river, from Yuval Mintz, Manish Chopra, and Sudarsana Kalluru. 27) Don't fetch timestamps on AF_UNIX sockets, from Hannes Frederic Sowa. 28) Support ipv6 geneve tunnels, from John W Linville. 29) Add flood control support to switchdev layer, from Ido Schimmel. 30) Fix CHECKSUM_PARTIAL handling of potentially fragmented frames, from Hannes Frederic Sowa. 31) Support persistent maps and progs in bpf, from Daniel Borkmann. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1790 commits) sh_eth: use DMA barriers switchdev: respect SKIP_EOPNOTSUPP flag in case there is no recursion net: sched: kill dead code in sch_choke.c irda: Delete an unnecessary check before the function call "irlmp_unregister_service" net: dsa: mv88e6xxx: include DSA ports in VLANs net: dsa: mv88e6xxx: disable SA learning for DSA and CPU ports net/core: fix for_each_netdev_feature vlan: Invoke driver vlan hooks only if device is present arcnet/com20020: add LEDS_CLASS dependency bpf, verifier: annotate verbose printer with __printf dp83640: Only wait for timestamps for packets with timestamping enabled. ptp: Change ptp_class to a proper bitmask dp83640: Prune rx timestamp list before reading from it dp83640: Delay scheduled work. dp83640: Include hash in timestamp/packet matching ipv6: fix tunnel error handling net/mlx5e: Fix LSO vlan insertion net/mlx5e: Re-eanble client vlan TX acceleration net/mlx5e: Return error in case mlx5e_set_features() fails net/mlx5e: Don't allow more than max supported channels ...

2015-11-03Merge branch 'perf-core-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull perf updates from Ingo Molnar: "Kernel side changes: - Improve accuracy of perf/sched clock on x86. (Adrian Hunter) - Intel DS and BTS updates. (Alexander Shishkin) - Intel cstate PMU support. (Kan Liang) - Add group read support to perf_event_read(). (Peter Zijlstra) - Branch call hardware sampling support, implemented on x86 and PowerPC. (Stephane Eranian) - Event groups transactional interface enhancements. (Sukadev Bhattiprolu) - Enable proper x86/intel/uncore PMU support on multi-segment PCI systems. (Taku Izumi) - ... misc fixes and cleanups. The perf tooling team was very busy again with 200+ commits, the full diff doesn't fit into lkml size limits. Here's an (incomplete) list of the tooling highlights: New features: - Change the default event used in all tools (record/top): use the most precise "cycles" hw counter available, i.e. when the user doesn't specify any event, it will try using cycles:ppp, cycles:pp, etc and fall back transparently until it finds a working counter. (Arnaldo Carvalho de Melo) - Integration of perf with eBPF that, given an eBPF .c source file (or .o file built for the 'bpf' target with clang), will get it automatically built, validated and loaded into the kernel via the sys_bpf syscall, which can then be used and seen using 'perf trace' and other tools. (Wang Nan) Various user interface improvements: - Automatic pager invocation on long help output. (Namhyung Kim) - Search for more options when passing args to -h, e.g.: (Arnaldo Carvalho de Melo) $ perf report -h interface Usage: perf report [<options>] --gtk Use the GTK2 interface --stdio Use the stdio interface --tui Use the TUI interface - Show ordered command line options when -h is used or when an unknown option is specified. (Arnaldo Carvalho de Melo) - If options are passed after -h, show just its descriptions, not all options. (Arnaldo Carvalho de Melo) - Implement column based horizontal scrolling in the hists browser (top, report), making it possible to use the TUI for things like 'perf mem report' where there are many more columns than can fit in a terminal. (Arnaldo Carvalho de Melo) - Enhance the error reporting of tracepoint event parsing, e.g.: $ oldperf record -e sched:sched_switc usleep 1 event syntax error: 'sched:sched_switc' \___ unknown tracepoint Run 'perf list' for a list of valid events Now we get the much nicer: $ perf record -e sched:sched_switc ls event syntax error: 'sched:sched_switc' \___ can't access trace events Error: No permissions to read /sys/kernel/debug/tracing/events/sched/sched_switc Hint: Try 'sudo mount -o remount,mode=755 /sys/kernel/debug' And after we have those mount point permissions fixed: $ perf record -e sched:sched_switc ls event syntax error: 'sched:sched_switc' \___ unknown tracepoint Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not found. Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?. I.e. basically now the event parsing routing uses the strerror_open() routines introduced by and used in 'perf trace' work. (Jiri Olsa) - Fail properly when pattern matching fails to find a tracepoint, i.e. '-e non:existent' was being correctly handled, with a proper error message about that not being a valid event, but '-e non:existent*' wasn't, fix it. (Jiri Olsa) - Do event name substring search as last resort in 'perf list'. (Arnaldo Carvalho de Melo) E.g.: # perf list clock List of pre-defined events (to be used in -e): cpu-clock [Software event] task-clock [Software event] uncore_cbox_0/clockticks/ [Kernel PMU event] uncore_cbox_1/clockticks/ [Kernel PMU event] kvm:kvm_pvclock_update [Tracepoint event] kvm:kvm_update_master_clock [Tracepoint event] power:clock_disable [Tracepoint event] power:clock_enable [Tracepoint event] power:clock_set_rate [Tracepoint event] syscalls:sys_enter_clock_adjtime [Tracepoint event] syscalls:sys_enter_clock_getres [Tracepoint event] syscalls:sys_enter_clock_gettime [Tracepoint event] syscalls:sys_enter_clock_nanosleep [Tracepoint event] syscalls:sys_enter_clock_settime [Tracepoint event] syscalls:sys_exit_clock_adjtime [Tracepoint event] syscalls:sys_exit_clock_getres [Tracepoint event] syscalls:sys_exit_clock_gettime [Tracepoint event] syscalls:sys_exit_clock_nanosleep [Tracepoint event] syscalls:sys_exit_clock_settime [Tracepoint event] Intel PT hardware tracing enhancements: - Accept a zero --itrace period, meaning "as often as possible". In the case of Intel PT that is the same as a period of 1 and a unit of 'instructions' (i.e. --itrace=i1i). (Adrian Hunter) - Harmonize itrace's synthesized callchains with the existing --max-stack tool option. (Adrian Hunter) - Allow time to be displayed in nanoseconds in 'perf script'. (Adrian Hunter) - Fix potential infinite loop when handling Intel PT timestamps. (Adrian Hunter) - Slighly improve Intel PT debug logging. (Adrian Hunter) - Warn when AUX data has been lost, just like when processing PERF_RECORD_LOST. (Adrian Hunter) - Further document export-to-postgresql.py script. (Adrian Hunter) - Add option to synthesize branch stack from auxtrace data. (Adrian Hunter) Misc notable changes: - Switch the default callchain output mode to 'graph,0.5,caller', to make it look like the default for other tools, reducing the learning curve for people used to 'caller' based viewing. (Arnaldo Carvalho de Melo) - various call chain usability enhancements. (Namhyung Kim) - Introduce the 'P' event modifier, meaning 'max precision level, please', i.e.: $ perf record -e cycles:P usleep 1 Is now similar to: $ perf record usleep 1 Useful, for instance, when specifying multiple events. (Jiri Olsa) - Add 'socket' sort entry, to sort by the processor socket in 'perf top' and 'perf report'. (Kan Liang) - Introduce --socket-filter to 'perf report', for filtering by processor socket. (Kan Liang) - Add new "Zoom into Processor Socket" operation in the perf hists browser, used in 'perf top' and 'perf report'. (Kan Liang) - Allow probing on kmodules without DWARF.

2015-11-03atomic: remove all traces of READ_ONCE_CTRL() and atomic*_read_ctrl()Linus Torvalds
This seems to be a mis-reading of how alpha memory ordering works, and is not backed up by the alpha architecture manual. The helper functions don't do anything special on any other architectures, and the arguments that support them being safe on other architectures also argue that they are safe on alpha. Basically, the "control dependency" is between a previous read and a subsequent write that is dependent on the value read. Even if the subsequent write is actually done speculatively, there is no way that such a speculative write could be made visible to other cpu's until it has been committed, which requires validating the speculation. Note that most weakely ordered architectures (very much including alpha) do not guarantee any ordering relationship between two loads that depend on each other on a control dependency: read A if (val == 1) read B because the conditional may be predicted, and the "read B" may be speculatively moved up to before reading the value A. So we require the user to insert a smp_rmb() between the two accesses to be correct: read A; if (A == 1) smp_rmb() read B Alpha is further special in that it can break that ordering even if the *address* of B depends on the read of A, because the cacheline that is read later may be stale unless you have a memory barrier in between the pointer read and the read of the value behind a pointer: read ptr read offset(ptr) whereas all other weakly ordered architectures guarantee that the data dependency (as opposed to just a control dependency) will order the two accesses. As a result, alpha needs a "smp_read_barrier_depends()" in between those two reads for them to be ordered. The coontrol dependency that "READ_ONCE_CTRL()" and "atomic_read_ctrl()" had was a control dependency to a subsequent *write*, however, and nobody can finalize such a subsequent write without having actually done the read. And were you to write such a value to a "stale" cacheline (the way the unordered reads came to be), that would seem to lose the write entirely. So the things that make alpha able to re-order reads even more aggressively than other weak architectures do not seem to be relevant for a subsequent write. Alpha memory ordering may be strange, but there's no real indication that it is *that* strange. Also, the alpha architecture reference manual very explicitly talks about the definition of "Dependence Constraints" in section, where a preceding read dominates a subsequent write. Such a dependence constraint admittedly does not impose a BEFORE (alpha architecture term for globally visible ordering), but it does guarantee that there can be no "causal loop". I don't see how you could avoid such a loop if another cpu could see the stored value and then impact the value of the first read. Put another way: the read and the write could not be seen as being out of order wrt other cpus. So I do not see how these "x_ctrl()" functions can currently be necessary. I may have to eat my words at some point, but in the absense of clear proof that alpha actually needs this, or indeed even an explanation of how alpha could _possibly_ need it, I do not believe these functions are called for. And if it turns out that alpha really _does_ need a barrier for this case, that barrier still should not be "smp_read_barrier_depends()". We'd have to make up some new speciality barrier just for alpha, along with the documentation for why it really is necessary.

As pointed out by Nikolay and further explained by Geert, the initial for_each_netdev_feature macro was broken, as feature would get set outside of the block of code it was intended to run in, thus only ever working for the first feature bit in the mask. While less pretty this way, this is tested and confirmed functional with multiple feature bits set in NETIF_F_UPPER_DISABLES. [root@dell-per730-01 ~]# ethtool -K bond0 lro off ...

2015-11-03arcnet/com20020: add LEDS_CLASS dependencyArnd Bergmann
The newly added led trigger support in the com20020-pci driver causes build errors when CONFIG_LEDS_CLASS is disabled: drivers/built-in.o: In function `com20020pci_probe': (.text+0x185dc4): undefined reference to `devm_led_classdev_register' (.text+0x185dd8): undefined reference to `devm_led_classdev_register' This adds a Kconfig dependency to prevent the invalid configurations. Other drivers appear to be split 50:50 between 'select' and 'depends on' for this symbol, I picked 'depends on' as I could not find a common policy and it generally causes fewer problems.

2015-11-03dp83640: Prune rx timestamp list before reading from itStefan Sørensen
The list of rx timestamps are currently only pruned of old entries when a new entry is inserted. If no new entries are added, old timestamps may survive beyond their lifetime, possible causing them to be attached to packets with the same sequence number after a rollover.

2015-11-03dp83640: Delay scheduled work.Stefan Sørensen
Currently rx_timestamp_work reschedules itself as a regular workqueue item, effectively causing it run constantly as long as there are packets left in the queue.

2015-11-03dp83640: Include hash in timestamp/packet matchingStefan Sørensen
Only using the message type and sequence id for matching timestamps with packets is error prone, as multiple clients may very well be sending packets with the same messagetype and timestamp at the same time. Fix by extending the check to include the hash of bytes 20-29 (source id in PTPv2) that is provided with the timestamps.

2015-11-03ipv6: fix tunnel error handlingMichal Kubeček
Both tunnel6_protocol and tunnel46_protocol share the same error handler, tunnel6_err(), which traverses through tunnel6_handlers list. For ipip6 tunnels, we need to traverse tunnel46_handlers as we do e.g. in tunnel46_rcv(). Current code can generate an ICMPv6 error message with an IPv4 packet embedded in it.
