2017-10-13VPP-1027: DNS name resolverDave Barach14-9/+3205
This patch is a plausible first-cut, suitable for initial testing by vcl (host stack client library). Main features; - recursive name resolution - multiple ip4/ip6 name servers - cache size limit enforcement - currently limited to 65K - ttl / aging - static mapping support - show / clear / debug CLI commands Binary APIs provided for the following: - add/delete name servers - enable/disable the name cache - resolve a name To Do list: - Respond to ip4/ip6 client DNS requests (vs. binary API requests) - Perf / scale tuning - map pending transaction ids to pool indices, so the cache can (greatly) exceed 65K entries - Security improvements - Use unpredictable dns transaction IDs, related to previous item - Make sure that response-packet src ip addresses match the server - Add binary APIs - deliver raw response data to clients - control recursive name resolution - Documentation Change-Id: I48c373d5c05d7108ccd814d4055caf8c75ca10b7 Signed-off-by: Dave Barach <dave@barachs.net>
2017-10-13acl-plugin: split the "show" commands and add an option to show ACLs by ↵Andrew Yourtchenko1-317/+407
interface From the troubleshooting perspective, it is nice to immediately know the ACEs for the ACLs applied to an interface, so implement that. To make the CLI more friendly, split each of the "show" variants into an independent _cmd function with the distinct CLI path.

2017-10-10session: add support for application namespacingFlorin Coras43-793/+2927
Applications are now provided the option to select the namespace they are to be attached to and the scope of their attachement. Application namespaces are meant to: 1) constrain the scope of communication through the network by association with source interfaces and/or fib tables that provide the source ips to be used and limit the scope of routing 2) provide a namespace local scope to session layer communication, as opposed to the global scope provided by 1). That is, sessions can be established without assistance from transport and network layers. Albeit, zero/local-host ip addresses must still be provided in session establishment messages due to existing application idiosyncrasies. This mode of communication uses shared-memory fifos (cut-through sessions) exclusively. If applications request no namespace, they are assigned to the default one, which at its turn uses the default fib. Applications can request access to both local and global scopes for a namespace. If no scope is specified, session layer defaults to the global one. When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY) binds are converted to binds to the requested interface.

2017-10-10jvpp: adding callbacks for all messages (VPP-914)Matej Perina21-147/+171
1) In the previous version callbacks were generated based on request-replay naming conventions. It turned out they were too strict in case of events (e.g. BFD sends Details messages as notifications). So now we generate callback for all messages, allowing to receive any message as notification.(callback_gen.py) 2) "notification" suffix is no longer added because all messages are treated same (dto_gen.py, jvpp_c_gen_.py) 3) name of property that holds notification/events changed in callback facade and future apis 4) JVppNotification.java is no longer used since all events are treated equally Change-Id: I13f6438affc3473040d63cd4acb3984d03e97482 Signed-off-by: Matej <matej.perina@pantheon.tech>

A bug was reported where a jumbo packet would stay in vhost queue forever or until a large enough number of other packets arrived in the queue too. This is due to a bug in vhost input node buffer allocation. The fix is to make sure that vhost always allocates at least enough buffers for one single big packet.

2017-10-09Allow use of /etc/os-release fileMarco Varlese1-1/+1
The top-level Makefile in VPP already uses the file /etc/os-release to recognize which OS the build is being performed on. The scripts for vagrant images instead were still using different files for different distros and adding a new distro to be supported causes issues with the extra-logic to deal with it. This patch aligns the vagrant scripts to use the same approach followed by the top-level Makefile and simplifies the steps to identify / update the OS and build / run VPP.

https://gerrit.fd.io/r/#/c/8551/ decoupled the global variable, namely tm->iovecs from TX and RX. However, to support multi-threads, we have to eliminate the use of this global variable with per thread variable. I notice that rx_buffers must also be per thread variable. So, we introduce per thread struct to contain rx_buffers and iovecs. Each thread will find the per thread struct with thread_index.

This patch reworks the DPDK ipsec implementation including the cryptodev management as well as replacing new cli commands for better usability. For the data path: - The dpdk-esp-encrypt-post node is not necessary anymore. - IPv4 packets in the decrypt path are sent to ip4-input-no-checksum instead of ip4-input. The DPDK cryptodev cli commands are replaced by the following new commands: - show dpdk crypto devices - show dpdk crypto placement [verbose] - set dpdk crypto placement (<device> <thread> | auto) - clear dpdk crypto placement <device> [<thread>] - show dpdk crypto pools Change-Id: I47324517ede82d3e6e0e9f9c71c1a3433714b27b Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>

2017-10-05Distributed Virtual Router SupportNeale Ranns13-109/+545
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

2017-10-04dpdk: use vpp physmem allocator for dpdk buffersDamjan Marion2-63/+144
This allows us to have single contignuous allocation for DPDK buffers with single mmap FD, so buffer memory can be easily shared with diffrent process. As a consequence dpdk socket-mem is no longer in charge for allocating buffer memory, but still we need some space allocated for dpdk structures so default socket-mem is reduced form 256 to 64 MB. For a default of 16K buffers per numa node, physmem allocation is now 40MB, so basically this change reduces footprint from 256MB per socket to 48 (64 + 40).

2017-09-28tun/tap: Bad packets sent to kernel via tun/tap interfaceSteven2-22/+29
It was observed that under heavy traffic, VPP accidentally sent traffic with the wrong source and destination to the tun/tap interface. Traffic appears to be sent to the wrong direction. This problem is only seen when worker thread is configured. When worker thread is used, TX and RX may reside in different core. Yet both TX and RX threads are sharing the same global variable, namely iovecs without any mutex or memory barrier protection. This creates a race condition when heavy traffic is blasted to VPP, like 1000 pps. We could create a mutex or memory barrier to ensure atomic memory access. But why bother? It is a lot cheaper to just decouple the iovecs such that TX and RX have their own iovecs. Change-Id: I86a5a19bd8de54d54f32e1f0845bae6a81bbf686 Signed-off-by: Steven <sluong@cisco.com>
