Version 2.8.10 - 7 April 2021

Bugfixes 🐛

  • cfdf116 DNS lookup responses with no answer records are not cached

As a temporary fix, the simple DNS cache is used on this patch release.

Version 2.8.9 - 25 March 2021

Improvements 💡

  • #343 Update alpine to 3.13 for Dockerfile

(C) musl-1.2.1.tar.gz (sig) - August 4, 2020 This release features the new "mallocng" malloc implementation, replacing musl's original dlmalloc-like allocator that suffered from fundamental design problems. Its major user-facing new properties are the ability to return freed memory on a much finer granularity and avoidance of many catastrophic fragmentation patterns. In addition it provides strong hardening against memory usage errors by the caller, including detection of overflows, double-free, and use-after-free, and does not admit corruption of allocator state via these errors.

  • improve GTP Path Maintenance procedures. NOTE: In GTP proxy use of ergw the path maintenance now stops forwarding traffic to a non-responsive target PGW after it detects, based on GTP echo probes, that it is not reachable. The PGW path is blocked for a configurable duration (default 1 hour) for forwarding. The configuration of the duration is done with the down_timeout parameter of the path_management section in the node config (see: config/ergw-c-node.config for example)

  • unify socket definition. NOTE: this requires changes to the configuration of ergw: sx_socket is removed from the ergw configuration, sx socket is now handled in the sockets section of ergw. See config/ergw-c-node.config for an example.
