Any network object between node X and destination is capable of handling MTU >= Y. In no case the kernel will allow us to send packets > Y. Signed-off-by: Fabio M.

Di Nitto <fdinitto(a)redhat.com> Date: 2018-01-02 (Tue, 02 Jan 2018) Changed paths: M libknet/internals.h M libknet/tests/knet_bench.c M libknet/threads_pmtud.c M libknet/transport_udp.c Log Message: ----------- [PTMUd] if any threads receives a EMSGSIZE outside of a PMTUD run, force PTMUd to run Scenario: node X has MTU Y on the interface and application is sending packets with size >= Y. The interface MTU is suddenly reduced to < Y Before this change, the kernel would be dropping packets till the next PMTUd run. After this change, the PMTUd will be informed that it has to rerun (overriding the pmtud_interval), reducing the packet drop to a minimum. How to test: force knet_bench to send 1500 size packets with ping_data (requires code change) and start it. reduce MTU on the interface from 1500 to 1300 (for example) Notice an immediate trigger of PMTUd run in debug mode Note: going up, from 1300 to 1500 will wait for the next PMTUd re-run as there is no immediate way to detect this change unless we start listening to kernel netlink sockets with libnl3 (investigation in progress but not critical enough atm).
