There are two patches by Yegor Yefremov which convert the ti_hecc driver into a DT only driver, as there is no in-tree user of the old platform driver interface anymore. The next patch by Mario Kicherer adds network namespace support to the can subsystem. The last two patches by Akshay Bhat add support for the holt_hi311x SPI CAN driver. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-05rtnl: Add support for netdev event to link messagesVlad Yasevich
When netdev events happen, a rtnetlink_event() handler will send messages for every event in it's white list. These messages contain current information about a particular device, but they do not include the iformation about which event just happened. The consumer of the message has to try to infer this information. In some cases (ex: NETDEV_NOTIFY_PEERS), that is not possible. This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT that would have an encoding of the which event triggered this message. This would allow the the message consumer to easily determine if it is interested in a particular event or not. Signed-off-by: Vladislav Yasevich <vyasevic@redhat.com> Signed-off-by: David S.

2017-04-04can: initial support for network namespacesMario Kicherer
This patch adds initial support for network namespaces. The changes only enable support in the CAN raw, proc and af_can code. GW and BCM still have their checks that ensure that they are used only from the main namespace. The patch boils down to moving the global structures, i.e. the global filter list and their /proc stats, into a per-namespace structure and passing around the corresponding "struct net" in a lot of different places.

2017-04-03net: usbnet: support 64bit statsGreg Ungerer
Add support for the net stats64 counters to the usbnet core. With that in place put the hooks into every usbnet driver to use it. This is a strait forward addition of 64bit counters for RX and TX packet and byte counts. It is done in the same style as for the other net drivers that support stats64. Note that the other stats fields remain as 32bit sized values (error counts, etc). The motivation to add this is that it is not particularly difficult to get the RX and TX byte counts to wrap on 32bit platforms.

2017-04-01udp: use sk_protocol instead of pcflag to detect udplite socketsPaolo Abeni
In the udp_sock struct, the 'forward_deficit' and 'pcflag' fields share the same cacheline. While the first is dirtied by udp_recvmsg, the latter is read, possibly several times, by the bottom half processing to discriminate between udp and udplite sockets. With this patch, sk->sk_protocol is used to check is the socket is really an udplite one, avoiding some cache misses per packet and improving the performance under udp_flood with small packet up to 10%.

2017-04-01bpf: introduce BPF_PROG_TEST_RUN commandAlexei Starovoitov
development and testing of networking bpf programs is quite cumbersome. Despite availability of user space bpf interpreters the kernel is the ultimate authority and execution environment. Current test frameworks for TC include creation of netns, veth, qdiscs and use of various packet generators just to test functionality of a bpf program. XDP testing is even more complicated, since qemu needs to be started with gro/gso disabled and precise queue configuration, transferring of xdp program from host into guest, attaching to virtio/eth0 and generating traffic from the host while capturing the results from the guest. Moreover analyzing performance bottlenecks in XDP program is impossible in virtio environment, since cost of running the program is tiny comparing to the overhead of virtio packet processing, so performance testing can only be done on physical nic with another server generating traffic. Furthermore ongoing changes to user space control plane of production applications cannot be run on the test servers leaving bpf programs stubbed out for testing. Last but not least, the upstream llvm changes are validated by the bpf backend testsuite which has no ability to test the code generated. To improve this situation introduce BPF_PROG_TEST_RUN command to test and performance benchmark bpf programs. Joint work with Daniel Borkmann.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Or Gerlitz says: ==================== mlx5e-pedit 2017-03-28 This series adds support for offloading modifications of packet headers using ConnectX-5 HW header re-write as an action applied during packet steering. The offloaded SW mechanism is TC's pedit action. The offloading is supported for E-Switch steering of VF traffic in the SRIOV switchdev mode and for NIC (non eswitch) RX. One use-case for this offload on virtual networks, is when the hypervisor implements flow based router such as Open-Stack's DVR, where L2 headers of guest packets re-written with routers' MAC addresses and the IP TTL is decremented. Another use case (which can be applied in parallel with routing) is stateless NAT where guest L3/L4 headers are re-written. The series is built as follows: the 1st six patches are preperations which don't yet add new functionality, patches 7-8 add the FW APIs (data-structures and commands) for header re-write, and patch nine allows offloading driver to access pedit keys. The 10th patch is somehow the core of the series, where we translate from the pedit way to represent set of header modification elements to the FW API for that same matter. Once a set of HW modification is established, we register it with the FW and get a modify header ID. When this ID is used with an action during packet steering, the HW applies the header modification on the packet. Patches 11 and 12 implement the above logic as an offload for pedit action for the NIC and E-Switch use-cases. I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing and helping me testing this functionality on HW simulator, before it could be done with FW. ==================== Signed-off-by: David S.

2017-03-28net: break include loop netdevice.h, dsa.h, devlink.hAndrew Lunn
There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.

Add as well the modify header id into two intermediate structs and set it to the FTE.

2017-03-24net: phy: Allow splitting MDIO bus/device support from PHYsFlorian Fainelli
Introduce a new configuration symbol: MDIO_DEVICE which allows building the MDIO devices and bus code, without pulling in the entire Ethernet PHY library and devices code. PHYLIB nows select MDIO_DEVICE and the relevant Makefile files are updated to reflect that. When MDIO_DEVICE (MDIO bus/device only) is selected, but not PHYLIB, we have mdio-bus.ko as a loadable module, and it does not have a module_exit() function because the safety of removing a bus class is unclear. When both MDIO_DEVICE and PHYLIB are enabled, we need to assemble everything into a common loadable module: libphy.ko because of nasty circular dependencies between phy.c, phy_device.c and mdio_bus.c which are really tough to untangle.

2017-03-22bpf: Add hash of maps supportMartin KaFai Lau
This patch adds hash of maps support (hashmap->bpf_map). BPF_MAP_TYPE_HASH_OF_MAPS is added. A map-in-map contains a pointer to another map and lets call this pointer 'inner_map_ptr'. Notes on deleting inner_map_ptr from a hash map: 1. For BPF_F_NO_PREALLOC map-in-map, when deleting an inner_map_ptr, the htab_elem itself will go through a rcu grace period and the inner_map_ptr resides in the htab_elem. 2. For pre-allocated htab_elem (!BPF_F_NO_PREALLOC), when deleting an inner_map_ptr, the htab_elem may get reused immediately. This situation is similar to the existing prealloc-ated use cases. However, the bpf_map_fd_put_ptr() calls bpf_map_put() which calls inner_map->ops->map_free(inner_map) which will go through a rcu grace period (i.e. all bpf_map's map_free currently goes through a rcu grace period). Hence, the inner_map_ptr is still safe for the rcu reader side. This patch also includes BPF_MAP_TYPE_HASH_OF_MAPS to the check_map_prealloc() in the verifier. preallocation is a must for BPF_PROG_TYPE_PERF_EVENT. Hence, even we don't expect heavy updates to map-in-map, enforcing BPF_F_NO_PREALLOC for map-in-map is impossible without disallowing BPF_PROG_TYPE_PERF_EVENT from using map-in-map first.

2017-03-22bpf: Add array of maps supportMartin KaFai Lau
This patch adds a few helper funcs to enable map-in-map support (i.e. outer_map->inner_map). The first outer_map type BPF_MAP_TYPE_ARRAY_OF_MAPS is also added in this patch. The next patch will introduce a hash of maps type. Any bpf map type can be acted as an inner_map. The exception is BPF_MAP_TYPE_PROG_ARRAY because the extra level of indirection makes it harder to verify the owner_prog_type and owner_jited. Multi-level map-in-map is not supported (i.e. map->map is ok but not map->map->map). When adding an inner_map to an outer_map, it currently checks the map_type, key_size, value_size, map_flags, max_entries and ops. The verifier also uses those map's properties to do static analysis. map_flags is needed because we need to ensure BPF_PROG_TYPE_PERF_EVENT is using a preallocated hashtab for the inner_hash also. ops and max_entries are needed to generate inlined map-lookup instructions. For simplicity reason, a simple '==' test is used for both map_flags and max_entries. The equality of ops is implied by the equality of map_type. During outer_map creation time, an inner_map_fd is needed to create an outer_map. However, the inner_map_fd's life time does not depend on the outer_map. The inner_map_fd is merely used to initialize the inner_map_meta of the outer_map. Also, for the outer_map: * It allows element update and delete from syscall * It allows element lookup from bpf_prog The above is similar to the current fd_array pattern.

Optimize bpf_call -> bpf_map_lookup_elem() -> array_map_lookup_elem() into a sequence of bpf instructions. When JIT is on the sequence of bpf instructions is the sequence of native cpu instructions with significantly faster performance than indirect call and two function's prologue/epilogue.

2017-03-16net/mlx4_core: Avoid delays during VF driver device shutdownJack Morgenstein
Some Hypervisors detach VFs from VMs by instantly causing an FLR event to be generated for a VF. In the mlx4 case, this will cause that VF's comm channel to be disabled before the VM has an opportunity to invoke the VF device's "shutdown" method. For such Hypervisors, there is a race condition between the VF's shutdown method and its internal-error detection/reset thread. The internal-error detection/reset thread (which runs every 5 seconds) also detects a disabled comm channel. If the internal-error detection/reset flow wins the race, we still get delays (while that flow tries repeatedly to detect comm-channel recovery). The cited commit fixed the command timeout problem when the internal-error detection/reset flow loses the race. This commit avoids the unneeded delays when the internal-error detection/reset flow wins.

2017-03-15mqprio: Modify mqprio to pass user parameters via ndo_setup_tc.Amritha Nambiar
The configurable priority to traffic class mapping and the user specified queue ranges are used to configure the traffic class, overriding the hardware defaults when the 'hw' option is set to 0. However, when the 'hw' option is non-zero, the hardware QOS defaults are used. This patch makes it so that we can pass the data the user provided to ndo_setup_tc. This allows us to pull in the queue configuration if the user requested it as well as any additional hardware offload type requested by using a value other than 1 for the hw value. Finally it also provides a means for the device driver to return the level supported for the offload type via the qopt->hw value. Previously we were just always assuming the value to be 1, in the future values beyond just 1 may be supported.

This patch advances the qed* drivers into using the newer firmware - This solves several firmware bugs, mostly related [but not limited to] various init/deinit issues in various offloaded protocols. It also introduces a major 4-Cached SGE change in firmware, which can be seen in the storage drivers' changes. In addition, this firmware is required for supporting the new QL41xxx series of adapters; While this patch doesn't add the actual support, the firmware contains the necessary initialization & firmware logic to operate such adapters [actual support would be added later on].
