Set/Clear IPv4 Mapped Addresses (SCTP_I_WANT_MAPPED_V4_ADDR) > > This socket option is a Boolean flag which turns on or off the > mapping of IPv4 addresses. If this option is turned on, then IPv4 > addresses will be mapped to V6 representation. If this option is > turned off, then no mapping will be done of V4 addresses and a user > will receive both PF_INET6 and PF_INET type addresses on the socket. > See [RFC3542] for more details on mapped V6 addresses. > > This description isn't really in line with what the code does though. ... > Tested bind, getpeername, getsockname, connect, and recvmsg for proper > behaviour in v4mapped = 1 and 0 cases. > > Signed-off-by: Neil Horman <nhorman@xxxxxxxxxxxxx> > Tested-by: Jason Gunthorpe <jgunthorpe@xxxxxxxxxxxxxxxxxxxx> > Signed-off-by: Jason Gunthorpe <jgunthorpe@xxxxxxxxxxxxxxxxxxxx> This has been this way since pre-GIT times, so I'm applying this to net-next, thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
