Hi, We are trying to work on a UDP mount for ganesha, and need some feedback. For NLM lock recovery we use the node local ip address of ganesha server-node. It works perfectly fine with the TCP mount. But with the UDP mount we have seen that local rq_xprt->xp_local.nb.buf points to valid local-ip, however rq_xprt->xp_local.ss have ip address ADDR_ANY. (gdb) p *((struct sockaddr_in*)&reqdata->svc->rq_xprt->xp_local.ss) $2 = {sin_family = 2, sin_port = 264, sin_addr = {s_addr = 0}, sin_zero = "\000\000\000\000\000\000\000"} (gdb) p *((struct sockaddr_in*)reqdata->svc->rq_xprt->xp_local.nb.buf) $3 = {sin_family = 3, sin_port = 0, sin_addr = {s_addr = 2237796106}, sin_zero = "\n\017b\205\000\000\000"} Which causes problems in lock recovery and other functionalities. We have made some changes in the initialization code of local ip: https://github.com/nfs-ganesha/ntirpc/pull/273/files Which seems to resolve the issue of the local address being ADDR_ANY and lock recovery works fine. We are not sure that :- 1. Will this fix work with all kinds of clients? 2. Will this break any existing functionalities? Any feedback will be greatly appreciated. Thanks, Sagar Singh
