Or, there is the following interpretation: "This value does not override the global net.core.rmem_max." might mean "This value does not override the global net.core.rmem_max to the extent that it does not define the upper users can set with SO_RCVBUF. It does, however, override net.core.rmem_max if SO_RCVBUF is not used." This would be consistent with my findings. I'm not 100% confident about whether this is what the code does though, see my comment http://stackoverflow.com/questions/31546835/tcp-receiving-window-size-higher-than-net-core-rmem-max/35438236#comment58576526_35438236 for details on that.
