Functions¶
funcPacketWasTruncated¶
PacketWasTruncated reports whether err indicates truncation but the RecvFromthat generated err was otherwise successful. On Windows, Go's UDP RecvFromcalls WSARecvFrom which returns the WSAEMSGSIZE error code when the receiveddatagram is larger than the provided buffer. When that happens, both a validsize and an error are returned (as per the partial fix for golang/go#14074).If the WSAEMSGSIZE error is returned, then we ignore the error to getsemantics similar to the POSIX operating systems. One caveat is that itappears that the source address is not returned when WSAEMSGSIZE occurs, butwe do not currently look at the source address.
funcShouldDisableUDPGSO¶added inv1.40.0
funcTreatAsLostUDP¶
TreatAsLostUDP reports whether err is an error from a UDP sendoperation that should be treated as a UDP packet that just gotlost.
Notably, on Linux this reports true for EPERM errors (from outboundfirewall blocks) which aren't really send errors; they're justsends that are never going to make it because the local OS blockedit.
