Both xdr_buf.len and iov.iov_len are size_t, which is unsigned; so use an unsigned type for our temporary length variable to ensure we don't overflow it..

| * SUNRPC: Fix default hostname created in rpc_create()J. Bruce Fields2007-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 43780b87fa7..., rpc_create() fills in a default hostname based on the ip address if the servername passed in is null. A small typo made that default incorrect. (But this information appears to be used only for debugging right now, so I don't believe the typo causes any bugs in the current kernel.)

| * nfs: add server port to rpc_pipe info fileJ. Bruce Fields2007-10-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the client, when an alternate server port is specified on the mount commandline, we need to make sure gssd knows about it. Also, on the server side, when we're sending krb5 callbacks to the client, we'll use the same mechanism to let gssd know about the callback port.

| * SUNRPC: RPC bind failures should be permanent for NULL requestsChuck Lever2007-10-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of an RPC ping (a NULL request) is to determine whether the remote end is operating and supports the RPC program and version of the request. If we do an RPC bind and the remote's rpcbind service says "this program or service isn't supported" then we have our answer already, and we should give up immediately. This is good for the kernel mount client, as it will cause the request to fail, and then allow an immediate retry with different options.

| * SUNRPC: Split another new rpcbind retry error code from EACCESChuck Lever2007-10-092-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add more new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns EACCES) Case 2: retry with a lesser rpcbind version (rpcb now returns EPFNOSUPPORT) This change allows more specific error processing for each of these two cases. We now fail case 2 instead of retrying... it's a server configuration error not to support even rpcbind version 2. And don't expose this new error code to user land -- convert it to EIO before failing the RPC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix some problems with rpcbind v3 and v4 queries from the in-kernel rpcbind client: 1. The r_addr argument must be a full universal address, not just an IP address, and 2. The universal address in r_addr is the address of the remote rpcbind server, not the RPC service being requested This addresses bugzilla.kernel.org report 8891 for 2.6.23-rc and greater.
