2018-07-04net/sched: Make etf report drops on error_queueJesus Sanchez-Palencia1-1/+2
Use the socket error queue for reporting dropped packets if the socket has enabled that feature through the SO_TXTIME API. Packets are dropped either on enqueue() if they aren't accepted by the qdisc or on dequeue() if the system misses their deadline. Those are reported as different errors so applications can react accordingly. Userspace can retrieve the errors through the socket error queue and the corresponding cmsg interfaces. A struct sock_extended_err* is used for returning the error data, and the packet's timestamp can be retrieved by adding both ee_data and ee_info fields as e.g.: ((__u64) serr->ee_data << 32) + serr->ee_info This feature is disabled by default and must be explicitly enabled by applications. Enabling it can bring some overhead for the Tx cycles of the application. Signed-off-by: Jesus Sanchez-Palencia <jesus.sanchez-palencia@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-07-04net/sched: Add HW offloading capability to ETFJesus Sanchez-Palencia1-0/+5
Add infra so etf qdisc supports HW offload of time-based transmission. For hw offload, the time sorted list is still used, so packets are dequeued always in order of txtime. Example: $ tc qdisc replace dev enp2s0 parent root handle 100 mqprio num_tc 3 \ map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 0 $ tc qdisc add dev enp2s0 parent 100:1 etf offload delta 100000 \ clockid CLOCK_REALTIME In this example, the Qdisc will use HW offload for the control of the transmission time through the network adapter. The hrtimer used for packets scheduling inside the qdisc will use the clockid CLOCK_REALTIME as reference and packets leave the Qdisc "delta" (100000) nanoseconds before their transmission time. Because this will be using HW offload and since dynamic clocks are not supported by the hrtimer, the system clock and the PHC clock must be synchronized for this mode to behave as expected.

2018-07-04net: ipv4: listified version of ip_rcvEdward Cree1-0/+2
Also involved adding a way to run a netfilter hook over a list of packets. Rather than attempting to make netfilter know about lists (which would be a major project in itself) we just let it call the regular okfn (in this case ip_rcv_finish()) for any packets it steals, and have it give us back a list of packets it's synchronously accepted (which normally NF_HOOK would automatically call okfn() on, but we want to be able to potentially pass the list to a listified version of okfn().) The netfilter hooks themselves are indirect calls that still happen per- packet (see nf_hook_entry_hookfn()), but again, changing that can be left for future work. There is potential for out-of-order receives if the netfilter hook ends up synchronously stealing packets, as they will be processed before any accepts earlier in the list. However, it was already possible for an asynchronous accept to cause out-of-order receives, so presumably this is considered OK.

2018-07-04sctp: add support for dscp and flowlabel per transportXin Long1-0/+9
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.

2018-06-30net/smc: add base infrastructure for SMC-D and ISMHans Wippel1-0/+62
SMC supports two variants: SMC-R and SMC-D. For data transport, SMC-R uses RDMA devices, SMC-D uses so-called Internal Shared Memory (ISM) devices. An ISM device only allows shared memory communication between SMC instances on the same machine. For example, this allows virtual machines on the same host to communicate via SMC without RDMA devices. This patch adds the base infrastructure for SMC-D and ISM devices to the existing SMC code. It contains the following: * ISM driver interface: This interface allows an ISM driver to register ISM devices in SMC. In the process, the driver provides a set of device ops for each device. SMC uses these ops to execute SMC specific operations on or transfer data over the device. * Core SMC-D link group, connection, and buffer support: Link groups, SMC connections and SMC buffers (in smc_core) are extended to support SMC-D. * SMC type checks: Some type checks are added to prevent using SMC-R specific code for SMC-D and vice versa. To actually use SMC-D, additional changes to pnetid, CLC, CDC, etc. are required. These are added in follow-up patches.

2018-06-29sctp: add support for SCTP_REUSE_PORT sockoptXin Long1-0/+1
This feature is actually already supported by sk->sk_reuse which can be set by socket level opt SO_REUSEADDR. But it's not working exactly as RFC6458 demands in section 8.1.27, like: - This option only supports one-to-one style SCTP sockets - This socket option must not be used after calling bind() or sctp_bindx(). Besides, SCTP_REUSE_PORT sockopt should be provided for user's programs. Otherwise, the programs with SCTP_REUSE_PORT from other systems will not work in linux. To separate it from the socket level version, this patch adds 'reuse' in sctp_sock and it works pretty much as sk->sk_reuse, but with some extra setup limitations that are needed when it is being enabled. "It should be noted that the behavior of the socket-level socket option to reuse ports and/or addresses for SCTP sockets is unspecified", so it leaves SO_REUSEADDR as is for the compatibility. Note that the name SCTP_REUSE_PORT is somewhat confusing, as its functionality is nearly identical to SO_REUSEADDR, but with some extra restrictions. Here it uses 'reuse' in sctp_sock instead of 'reuseport'. As for sk->sk_reuseport support for SCTP, it will be added in another patch. Thanks to Neil to make this clear. v1->v2: - add sctp_sk->reuse to separate it from the socket level version. v2->v3: - improve changelog according to Marcelo's suggestion.

2018-06-28Revert changes to convert to ->poll_mask() and aio IOCB_CMD_POLLLinus Torvalds6-6/+12
The poll() changes were not well thought out, and completely unexplained. They also caused a huge performance regression, because "->poll()" was no longer a trivial file operation that just called down to the underlying file operations, but instead did at least two indirect calls. Indirect calls are sadly slow now with the Spectre mitigation, but the performance problem could at least be largely mitigated by changing the "->get_poll_head()" operation to just have a per-file-descriptor pointer to the poll head instead. That gets rid of one of the new indirections. But that doesn't fix the new complexity that is completely unwarranted for the regular case. The (undocumented) reason for the poll() changes was some alleged AIO poll race fixing, but we don't make the common case slower and more complex for some uncommon special case, so this all really needs way more explanations and most likely a fundamental redesign.

2018-06-27nfp: reject binding to shared blocksJohn Hurley1-0/+5
TC shared blocks allow multiple qdiscs to be grouped together and filters shared between them. Currently the chains of filters attached to a block are only flushed when the block is removed. If a qdisc is removed from a block but the block still exists, flow del messages are not passed to the callback registered for that qdisc. For the NFP, this presents the possibility of rules still existing in hw when they should be removed. Prevent binding to shared blocks until the kernel can send per qdisc del messages when block unbinds occur. tcf_block_shared() was not used outside of the core until now, so also add an empty implementation for builds with CONFIG_NET_CLS=n.

Call the reoffload tcf_proto_op on all tcf_proto nodes in all chains of a block when a callback tries to register to a block that already has offloaded rules. If all existing rules cannot be offloaded then the registration is rejected. This replaces the previous policy of rejecting such callback registration outright. On unregistration of a callback, the rules are flushed for that given cb. The implementation of block sharing in the NFP driver, for example, duplicates shared rules to all devs bound to a block. This meant that rules could still exist in hw even after a device is unbound from a block (assuming the block still remains active).
