2017-10-14vhost: crash under heavy traffic condition due to memory corruption (VPP-1016)Steven1-2/+33
With heavy traffic, tx code path may crash due to memory corruption Thread 5 "vpp_wk_2" received signal SIGSEGV, Segmentation fault.

The assignment here in cpy surely causes memory corruption. It is only discovered later when the memory location that it corrupted is used. The condition for the crash is to transmit jumbo frames under heavy volume. Since ring size is 1024, with one packet taking up one index for frame size (less 2048), it does not cause overflow. With jumbo frames, it requires multiple indices for one packet, it can cause the overflow under heavy traffic. The fix is to do copy out when we have 1000 entries in the array to avoid overflow.

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>

2017-10-10session: 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.

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>

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.

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).

2017-10-03Repair vlib API socket serverDave Barach87-1104/+2510
- Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (<pid>, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-09-28cdp/lldp: punt for no bufferSteven2-0/+6
When making a call to vlib_packet_template_get_packet(), it is possible to get back a NULL if the system runs out of buffer. This can happen when there is buffer leaks. But don't crash just because we run out of buffers, just punt. Change-Id: Ie90ea41f3dda6e583d48959cbd18ff124158d7f8 Signed-off-by: Steven <sluong@cisco.com>
