2018-05-16sched: manipulate __QDISC_STATE_RUNNING in qdisc_run_* helpersPaolo Abeni
Currently NOLOCK qdiscs pay a measurable overhead to atomically manipulate the __QDISC_STATE_RUNNING. Such bit is flipped twice per packet in the uncontended scenario with packet rate below the line rate: on packed dequeue and on the next, failing dequeue attempt. This changeset moves the bit manipulation into the qdisc_run_{begin,end} helpers, so that the bit is now flipped only once per packet, with measurable performance improvement in the uncontended scenario. This also allows simplifying the qdisc teardown code path - since qdisc_is_running() is now effective for each qdisc type - and avoid a possible race between qdisc_run() and dev_deactivate_many(), as now the some_qdisc_is_busy() can properly detect NOLOCK qdiscs being busy dequeuing packets.

If hclge.ko has not been inserted, the value of ret always is zero in hnae3_register_ae_dev. If hclge.ko has been inserted, the value of ret is zero or non zero. Different execution ways have different results. It is confusing. The ae_dev which is initialized failed can be reinitialized when we remove hclge.ko and insert it again. For the case initializing client instance, it is just like the case initializing ae_dev. The main function of hnae3_register_ae_dev is adding the ae_dev to ad_dev list. Because adding ae_dev is always ok, we does not need to return any in this function. This patch changes the return type of hnae3_register_ae_dev from int to void.

Since VF pci device is dependent on PF pci device, When PF pci device is removed, VF pci device must be removed. Also, To solve the deadlock problem, VF pci device should be removed before PF pci device is removed. This patch moves pci_enable/disable_sriov from hclge to hns3 to solve the deadlock problem.

This only has bridging (and STP) support for now and it uses the switchdev framework. Coming features are VLAN filtering, link aggregation, IGMP snooping. The switch can also be connected to an external CPU using PCIe. Also, support for integration on other SoCs will be submitted. The ocelot dts changes are here for reference and should probably go through the MIPS tree once the bindings are accepted. Changes in v3: - Collected Reviewed-by * Switchdev driver: - Fixed two issues reported by kbuild - Modified ethtool statistics to support different layoiut on different chips and take care of counter overflow Changes in v2: - Dropped Microsemi Ocelot PHY support * MIIM driver: - Documented interrupts bindings - Moved the driver to drivers/net/phy/ - Removed unused mutex - Removed MDIO bus scanning * Switchdev driver: - Changed compatible to mscc,vsc7514-switch - Removed unused header inclusion - Factorized MAC table selection in ocelot_mact_select() - Disable the port in ocelot_port_stop() - Fixed the smatch endianness warnings - int to unsinged int where necessary - Removed VID handling for the FDB it has been reworked anyway and will be submitted with VLAN support - Fixed up unused cases in ocelot_port_attr_set() - Added a loop to register all the IO register spaces - the ports are now in an ethernet-ports node I've tried switching to NAPI but this is not working well, mainly because the only way to disable interrupts is to actually mask them in the interrupt controller (it is not possible to tell the switch to stop generating interrupts). ==================== Signed-off-by: David S.

2018-05-15net: mscc: Add initial Ocelot switch supportAlexandre Belloni
Add a driver for Microsemi Ocelot Ethernet switch support. This makes two modules: mscc_ocelot_common handles all the common features that doesn't depend on how the switch is integrated in the SoC. Currently, it handles offloading bridging to the hardware. ocelot_io.c handles register accesses. This is unfortunately needed because the register layout is packed and then depends on the number of ports available on the switch. The register definition files are automatically generated. ocelot_board handles the switch integration on the SoC and on the board. Frame injection and extraction to/from the CPU port is currently done using register accesses which is quite slow. DMA is possible but the port is not able to absorb the whole switch bandwidth.

2018-05-15bpf: sockmap, add hash map supportJohn Fastabend
Sockmap is currently backed by an array and enforces keys to be four bytes. This works well for many use cases and was originally modeled after devmap which also uses four bytes keys. However, this has become limiting in larger use cases where a hash would be more appropriate. For example users may want to use the 5-tuple of the socket as the lookup key.

2018-05-15bpf: sockmap, refactor sockmap routines to work with hashmapJohn Fastabend
This patch only refactors the existing sockmap code. This will allow much of the psock initialization code path and bpf helper codes to work for both sockmap bpf map types that are backed by an array, the currently supported type, and the new hash backed bpf map type sockhash. Most the fallout comes from three changes, - Pushing bpf programs into an independent structure so we can use it from the htab struct in the next patch. - Generalizing helpers to use void *key instead of the hardcoded u32. - Instead of passing map/key through the metadata we now do the lookup inline. This avoids storing the key in the metadata which will be useful when keys can be longer than 4 bytes. We rename the sk pointers to sk_redir at this point as well to avoid any confusion between the current sk pointer and the redirect pointer sk_redir.

2018-05-14bpf, doc: rename txt files to rst filesJesper Dangaard Brouer
This will cause them to get auto rendered, e.g. when viewing them on GitHub. Followup patches will correct the content to be RST compliant. Also adjust README.rst to point to the renamed files.

2018-05-14bpf, doc: add basic README.rst fileJesper Dangaard Brouer
A README.rst file in a directory have special meaning for sites like github, which auto renders the contents. Plus search engines like Google also index these README.rst files. Auto rendering allow us to use links, for (re)directing eBPF users to other places where docs live. The end-goal would be to direct users towards https://www.kernel.org/doc/html/latest but we haven't written the full docs yet, so we start out small and take this incrementally. This directory itself contains some useful docs, which can be linked to from the README.rst file (verified this works for github).

2018-05-14Merge branch 'fix-samples'Alexei Starovoitov
Jakub Kicinski says: ==================== Following patches address build issues after recent move to libbpf. For out-of-tree builds we would see the following error: gcc: error: samples/bpf/../../tools/lib/bpf/libbpf.a: No such file or directory libbpf build system is now always invoked explicitly rather than relying on building single objects most of the time. We need to resolve the friction between Kbuild and tools/ build system. Mini-library called libbpf.h in samples is renamed to bpf_insn.h, using linux/filter.h seems not completely trivial since some samples get upset when order on include search path in changed. We do have to rename libbpf.h, however, because otherwise it's hard to reliably get to libbpf's header in out-of-tree builds. v2: - fix the build error harder (patch 3); - add patch 5 (make clang less noisy). ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2018-05-14samples: bpf: make the build less noisyJakub Kicinski
Building samples with clang ignores the $(Q) setting, always printing full command to the output. Make it less verbose. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
