Yesterday, the research node kernels have been updated:
- Linux kernel: v4.1.24 (before: v4.1.10)
- Linux MPTCP: v0.91 (before: v0.90)
- Explicit Congestion Notification (ECN), according to RFC 3168 and RFC 6040, is enabled by default (i.e. net.ipv4.tcp_ecn=1).
The update particularly fixes some stability issues (kernel lockups) during MPTCP usage.
