2018-03-14Prevent calling rte_eth_xstats_get not initialized devSzymon Sliwa1-0/+2
DPDK API forbids calling rte_eth_xstats_get on a port which has not been setup up yet. Citing the DPDK docs (reformated): " The functions exported by the application Ethernet API to setup a device designated by its port identifier must be invoked in the following order: rte_eth_dev_configure() rte_eth_tx_queue_setup() rte_eth_rx_queue_setup() rte_eth_dev_start() Then, the network application can invoke, in any order, the functions exported by the Ethernet API to get the MAC address of a given device, to get the speed and the status of a device physical link, to receive/transmit [burst of] packets, and so on.

2018-02-25Fix bug in dpdk_crypto_session_disposal()Matthew Smith1-0/+2
The expression to determine whether to delete a session from the disposal list only evaluates true if some, but not all, of the sessions in the list were freed. When all sessions in the list are freed, it evaluates false and the sessions are left in the list to be freed again later, which can result in a session pool element that was reallocated to a different SA being freed, breaking crypto for the newer SA. Add an 'else' that handles the case where all sessions were freed. Change-Id: I3ae54d5b3bfc3658bf406caa50646924baaae589 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2018-02-19dpdk: Fix MTU calc for NICs that support mtu<9216Nitin Saxena1-34/+66
Problem: rte_eth_dev_set_mtu() returns with failure from ThunderX NICVF DPDK PMD driver which supports MTU less than ETHERNET_MAX_PACKET_BYTES. rte_eth_dev_set_mtu() being called twice from dpdk_lib_init(): one via dpdk_device_setup() and second in dpdk_lib_init() itself. Currently dpdk_lib_init() passes vnet_hardware_interface->max_packet_bytes as an argument to rte_eth_dev_set_mtu() without consulting dev_info.max_rx_pktlen. NICs like i4oe, ixgbe can support MTU much greater than 9216 hence its not a problem for those NICS. Fix: This patch calculates dpdk_device->port_conf.rxmode.max_rx_pkt_len, vnet_hardware_interface->max_packet_bytes and MTU by consulting dev_info.max_rx_pktlen.

2018-02-08acl-plugin: add whitelisted ethertype mode (VPP-1163)Andrew Yourtchenko5-5/+308
Currently, ACL plugin largely does not care about the ethertypes other than 0x0800 (IPv4) and 0x86dd (IPv6), the only exception being 0x0806 (ARP), which is dealt with by the MACIP ACLs. The other ethertypes in L2 mode are just let through. This adds a new API message acl_interface_set_etype_whitelist, which allows to flip the mode of a given interface into "ethertype whitelist mode": the caller of this message must supply the two lists (inbound and outbound) of the ethertypes that are to be permitted, the rest of the ethertypes are dropped. The whitelisting for a given interface and direction takes effect only when a policy ACL is also applied. This operates on the same classifier node as the one used for dispatching the policy ACL, thus, if one wishes for most of the reasonable IPv4 deployments to continue to operate within the whitelist mode, they must permit ARP ethertype (0x0806) The empty list for a given direction resets the processing to allow the unknown ethertypes. So, if one wants to just permit the IPv4 and IPv6 and nothing else, one can add their ethertypes to the whitelist. Add the "show acl-plugin interface" corresponding outputs about the whitelists, vat command, and unittests.

2018-02-08acl-plugin: VPP-1088: add support for egress filter in macip ACLsAndrew Yourtchenko2-16/+244
This is the second patch, using the new functionality from the change 10002 in order to implement the egress filtering on the MACIP ACLs. This adds an action "2" which means "add also egress filtering rules for this MACIP ACL. The reason for having the two choices is that the egress filtering really takes care of a fairly corner case scenario, and I am not convinced that always adding the performance cost of the egress lookup check is worth it. Also, of course, not breaking the existing implementations is a nice plus, too. Change-Id: I3d7883ed45b1cdf98d7303771bcc75951dff38f0 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

conn cleaner threads interactions This replaces some of the early-stage commented-out printf()s with an elog-based debug collector. It is aimed to be "better than nothing" initial implementation to be available in the field. It will be refined/updated based on use. This initial code is focused on the main/worker threads interactions, hence uses just the worker tracks. This code adds a developer debug CLI "set acl-plugin session table event-trace 1", which allows to gather the events pertaining to connection cleaning. The CLI is deliberately not part of the online help, as the express declaration that the semantics/trace levels, etc. are subject to change without notice.

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-1/+1
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.
