Snabb Versions Save

This release improves compatibility of the vhost-user driver with current QEMU versions, and adds rudimentary PMU support for AMD family 15h+ CPUs (including Ryzen). With “Eggplant”, our high-performance hash table implementation received a callback that can be invoked when it is resized, and a generic Token Bucket implementation (lib.token_bucket) and time stamp counter module (lib.tsc) are introduced. As usual, this release comes with numerous bug fixes and minor enhancements.

• #1354 lib.pmu: rudimentary support for AMD family 15h+ CPUs
• #1359 Add optional callback to the CTable:resize() method
• #1355 Add support for RDTSC, apply to token bucket
• #1358 Add protocol header for ICMPv6 Packet-Too-Big type
• #1210 #1367 #1362 #1351 #1344 #1366 #1305 #1373 Various bug fixes and minor enhancements

This release introduces support for low-overhead packet queues between Snabb processes within the same process group, as well as a software-based “Receive Side Scaling” (RSS) app to pair with it. Dill also comes with basic pattern restriction support in lib.yang, a better in-band packet tap app that records Pcap data, and—as usual—various bug fixes and miscellaneous improvements.

Changes

• #1263 Adds basic support for pattern restrictions to lib.yang
• #1288 Adds a pair of apps (apps.interlink.transmitter and apps.interlink.receiver) that enable efficient packet I/O between Snabb processes within the same process group (inter-process links)

• #1315 Introduces the new snabbco/raptorjit integration branch
• #1320 Adds an in-band packet tap app that logs to Pcap data as a more efficient and featureful alternative to PcapWriter
• #1327 Fixes a bug in lib.protocol.tcp
• #1338 Fixes a bug in ljsyscall’s lseek wrapper

This release introduces a driver-agnostic interface to network interface cards (NIC), and switches over to the new intel_mp driver as the default choice. In addition, some efforts of making LuaJIT’s compiler more predictable have been back-ported from RaptorJIT to Snabb. Endive also includes various bug fixes as usual.

Major Changes

• #1229 Implemented VMDq, VLAN insert/remove for intel_mp driver
• #1199 #1234 #1236 #1248 Implemented driver-agnostic I/O interface
• #1237 Prefer intel_mp as the default driver
• #1242 Introduced jit.tracebarrier() primitive, to delimit JIT compiler traces
• #1244 luajit: Record calls to blacklisted functions the same way as calls to uncompiled functions (this fixes a pathological case where a blacklisting could cause cascading failures of the JIT compiler)

Minor Changes

• #1225 lib.hash.siphash: avoid ctype diversity for hash functions
• #1230 #1247 #1190 Various intel_mp improvements
• #1228 Fixed a bug in the wrapper of get_mempolicy(2) in ljsyscall
• #1245 In case of a segmentation fault, we now log various interesting details about the faulting address before exiting
• #1235 #1240 #1254 Minor bug fixes and enhancements

This release adds an optimized implementation of SipHash (a fast cryptographic hash function) to Snabb. Dandelion also comes with many goodies such as a command line option to identify the exact version of Snabb executables, as well as improves stack traces for snsh, the interactive Snabb shell. As usual, this release also includes many minor bug fixes, and performance as well as usability improvements.
