Xin Long says: ==================== sctp: fully support for dscp and flowlabel per transport Now dscp and flowlabel are set from sock when sending the packets, but being multi-homing, sctp also supports for dscp and flowlabel per transport, which is described in section 8.1.12 in RFC6458. v1->v2: - define ip_queue_xmit as inline in net/ip.h, instead of exporting it in Patch 1/5 according to David's suggestion. - fix the param len check in sctp_s/getsockopt_peer_addr_params() in Patch 3/5 to guarantee that an old app built with old kernel headers could work on the newer kernel per Marcelo's point. ==================== Signed-off-by:David S.

The transport with illegal flowlabel should not be allowed to send packets. Other transport protocols already denies this. Signed-off-by:

Struct sockaddr_in6 has the member sin6_flowinfo that includes the ipv6 flowlabel, it should also support for setting flowlabel when adding a transport whose ipaddr is from userspace. Note that addrinfo in sctp_sendmsg is using struct in6_addr for the secondary addrs, which doesn't contain sin6_flowinfo, and it needs to copy sin6_flowinfo from the primary addr. Signed-off-by:

spp_ipv6_flowlabel and spp_dscp are added in sctp_paddrparams in this patch so that users could set sctp_sock/asoc/transport dscp and flowlabel with spp_flags SPP_IPV6_FLOWLABEL or SPP_DSCP by SCTP_PEER_ADDR_PARAMS , as described section 8.1.12 in RFC6458. As said in last patch, it uses '| 0x100000' or '|0x1' to mark flowlabel or dscp is set, so that their values could be set to 0. Note that to guarantee that an old app built with old kernel headers could work on the newer kernel, the param's check in sctp_g/setsockopt_peer_addr_params() is also improved, which follows the way that sctp_g/setsockopt_delayed_ack() or some other sockopts' process that accept two types of params does.

Like some other per transport params, flowlabel and dscp are added in transport, asoc and sctp_sock. By default, transport sets its value from asoc's, and asoc does it from sctp_sock. flowlabel only works for ipv6 transport. Other than that they need to be passed down in sctp_xmit, flow4/6 also needs to set them before looking up route in get_dst. Note that it uses '& 0x100000' to check if flowlabel is set and '& 0x1' (tos 1st bit is unused) to check if dscp is set by users, so that they could be set to 0 by sockopt in next patch.

This patch introduces __ip_queue_xmit(), through which the callers can pass tos param into it without having to set inet->tos. For ipv6, ip6_xmit() already allows passing tclass parameter. It's needed when some transport protocol doesn't use inet->tos, like sctp's per transport dscp, which will be added in next patch. Signed-off-by:

This adds a DSA driver for: Vitesse VSC7385 SparX-G5 5-port Integrated Gigabit Ethernet Switch Vitesse VSC7388 SparX-G8 8-port Integrated Gigabit Ethernet Switch Vitesse VSC7395 SparX-G5e 5+1-port Integrated Gigabit Ethernet Switch Vitesse VSC7398 SparX-G8e 8-port Integrated Gigabit Ethernet Switch These switches have a built-in 8051 CPU and can download and execute firmware in this CPU. They can also be configured to use an external CPU handling the switch in a memory-mapped manner by connecting to that external CPU's memory bus. This driver (currently) only takes control of the switch chip over SPI and configures it to route packages around when connected to a CPU port. The chip has embedded PHYs and VLAN support so we model it using DSA as a best fit so we can easily add VLAN support and maybe later also exploit the internal frame header to get more direct control over the switch. The four built-in GPIO lines are exposed using a standard GPIO chip. Signed-off-by:

The VSC7385, VSC7388, VSC7395 and VSC7398 are integrated switch/router chips for 5+1 or 8-port switches/routers. When managed directly by Linux using DSA we need to do a special set-up "dance" on the PHY. Unfortunately these sequences switches the PHY to undocumented pages named 2a30 and 52b6 and does undocumented things. It is described by these opaque sequences also in the reference manual. This is a best effort to integrate it anyways. Reviewed-by:

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-07-03 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Various improvements to bpftool and libbpf, that is, bpftool build speed improvements, missing BPF program types added for detection by section name, ability to load programs from '.text' section is made to work again, and better bash completion handling, from Jakub. 2) Improvements to nfp JIT's map read handling which allows for optimizing memcpy from map to packet, from Jiong. 3) New BPF sample is added which demonstrates XDP in combination with bpf_perf_event_output() helper to sample packets on all CPUs, from Toke. 4) Add a new BPF kselftest case for tracking connect(2) BPF hooks infrastructure in combination with TFO, from Andrey. 5) Extend the XDP/BPF xdp_rxq_info sample code with a cmdline option to read payload from packet data in order to use it for benchmarking. Also for '--action XDP_TX' option implement swapping of MAC addresses to avoid drops on some hardware seen during testing, from Jesper. ==================== Signed-off-by: -

Igor Russkikh says: ==================== net: aquantia: various ethtool ops implementation In this patchset Anton Mikaev and I added some useful ethtool operations: - ring size changes - link renegotioation - flow control management The patch also improves init/deinit sequence. V3 changes: - After review and analysis it is clear that rtnl lock (which is captured by default on ethtool ops) is enough to secure possible overlapping of dev open/close. Thus, just dropping internal mutex. V2 changes: - using mutex to secure simultaneous dev close/open - using state var to store/restore dev state ==================== Signed-off-by: -

We now pass link drop status to FW on init/deinit. This is required to inform FW that driver took/released a control on link. FW then will manage its own state and device power profile based on this information. To improve management we remove mpi_set function which ambiguously took both state and speed parameters. Deinit callback is now a part of FW ops, as it actually manages the FW. Signed-off-by:

Currently trace_sock_exceed_buf_limit() only show rmem info, but wmem limit may also be hit. So expose wmem info in this tracepoint as well. Regarding memcg, I think it is better to introduce a new tracepoint(if that is needed), i.e. trace_memcg_limit_hit other than show memcg info in trace_sock_exceed_buf_limit. Signed-off-by:

This hack (affecting the non-PCIe models only) was introduced in 2004 to deal with link negotiation failures in 1GBit mode. Based on a comment in the r8169 vendor driver I assume the issue affects RTL8169sb in combination with particular 1GBit switch models. Resetting the PHY every 10s and hoping that one fine day we will make it to establish the link seems to be very hacky to me. I'd say: If 1GBit doesn't work reliably in a users environment then the user should remove 1GBit from the advertised modes, e.g. by using ethtool -s <if> advertise <10/100 modes> If the issue affects one chip version only and that with most link partners, then we could also think of removing 1GBit from the advertised modes for this chip version in the driver.
