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
