| * | svcrpc: treat uid's as unsignedJ. Bruce Fields2010-03-02

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One the changes in commit d7979ae4a "svc: Move close processing to a single place" is: err_delete: - svc_delete_socket(svsk); + set_bit(SK_CLOSE, &svsk->sk_flags); return -EAGAIN; This is insufficient. The recvfrom methods must always call svc_xprt_received on completion so that the socket gets re-queued if there is any more work to do. This particular path did not make that call because it actually destroyed the svsk, making requeue pointless. When the svc_delete_socket was change to just set a bit, we should have added a call to svc_xprt_received, This is the problem that b0401d7253 attempted to fix, incorrectly. Signed-off-by: J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'struct svc_deferred_req's on the xpt_deferred queue do not own a reference to the owning xprt. This is seen in svc_revisit which is where things are added to this queue. dr->xprt is set to NULL and the reference to the xprt it put. So when this list is cleaned up in svc_delete_xprt, we mustn't put the reference. Also, replace the 'for' with a 'while' which is arguably simpler and more likely to compile efficiently.

| * | SUNRPC: NFS kernel APIs shouldn't return ENOENT for "transport not found"Chuck Lever2010-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | write_ports() converts svc_create_xprt()'s ENOENT error return to EPROTONOSUPPORT so that rpc.nfsd (in user space) can report an error message that makes sense. It turns out that several of the other kernel APIs rpc.nfsd use can also return ENOENT from svc_create_xprt(), by way of lockd_up(). On the client side, an NFSv2 or NFSv3 mount request can also return the result of lockd_up(). This error may also be returned during an NFSv4 mount request, since the NFSv4 callback service uses svc_create_xprt() to create the callback listener. An ENOENT error return results in a confusing error message from the mount command. Let's have svc_create_xprt() return EPROTONOSUPPORT instead of ENOENT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up: Bruce observed we have more or less common logic in each of svc_create_xprt()'s callers: the check to create an IPv6 RPC listener socket only if CONFIG_IPV6 is set. I'm about to add another case that does just the same. If we move the ifdefs into __svc_xpo_create(), then svc_create_xprt() call sites can get rid of the "#ifdef" ugliness, and can use the same logic with or without IPv6 support available in the kernel.

|/ | | | | | | | | | | | | | | The kernel currently ignores any error code sent by gssd and always considers it to be -EACCES. In order to better handle the situation of an expired KRB5 TGT, the kernel needs to be able to parse and deal with the errors that gssd sends. Aside from -EACCES the only error we care about is -EKEYEXPIRED, which we're using to indicate that the upper layers should retry the call a little later. To maintain backward compatibility with older gssd's, any error other than -EKEYEXPIRED is interpreted as -EACCES.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling the gssd downcall, the kernel should distinguish between a successful downcall that contains an error code and a failed downcall (i.e. where the parsing failed or some other sort of problem occurred). In the former case, gss_pipe_downcall should be returning the number of bytes written to the pipe instead of an error. In the event of other errors, we generally want the initiating task to retry the upcall so we set msg.errno to -EAGAIN. An unexpected error code here is a bug however, so BUG() in that case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There're some warnings of "nfsd: peername failed (err 107)!" socket error -107 means Transport endpoint is not connected. This warning message was outputed by svc_tcp_accept() [net/sunrpc/svcsock.c], when kernel_getpeername returns -107. This means socket might be CLOSED. And svc_tcp_accept was called by svc_recv() [net/sunrpc/svc_xprt.c] if (test_bit(XPT_LISTENER, &xprt->xpt_flags)) { <snip> newxpt = xprt->xpt_ops->xpo_accept(xprt); <snip> So this might happen when xprt->xpt_flags has both XPT_LISTENER and XPT_CLOSE. Let's take a look at commit b0401d72, this commit has moved the close processing after do recvfrom method, but this commit also introduces this warnings, if the xpt_flags has both XPT_LISTENER and XPT_CLOSED, we should close it, not accpet then close.

| * | nfsd4: don't try to map gid's in generic rpc codeJ. Bruce Fields2009-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For nfsd we provide users the option of mapping uid's to server-side supplementary group lists. That makes sense for nfsd, but not necessarily for other rpc users (such as the callback client). So move that lookup to svcauth_unix_set_client, which is a program-specific method. Signed-off-by: J.

| | * | | SUNRPC: Use soft connect semantics when performing RPC pingChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if a remote RPC service is unreachable, an RPC ping will hang until the underlying transport connect attempt times out. A more desirable behavior might be to have the ping fail immediately so upper layers can recover appropriately. In the case of an NFS mount, for instance, this would mean the mount(2) system call could fail immediately if the server isn't listening, rather than hanging uninterruptibly for more than 3 minutes. Change rpc_ping() so that it fails immediately for connection-oriented transports. rpc_create() will then fail immediately for such transports if an RPC ping was requested.

| | * | | SUNRPC: Use soft connects for autobinding over TCPChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Autobinding is handled by the rpciod process, not in user processes that are generating regular RPC requests. Thus autobinding is usually not affected by signals targetting user processes, such as KILL or timer expiration events. In addition, an RPC request generated by a user process that has RPC_TASK_SOFTCONN set and needs to perform an autobind will hang if the remote rpcbind service is not available. For rpcbind queries on connection-oriented transports, let's use the new soft connect semantic to return control to the user's process quickly, if the kernel's rpcbind client can't connect to the remote rpcbind service. Logic is introduced in call_bind_status() to handle connection errors that occurred during an asynchronous rpcbind query. The logic abandons the rpcbind query if the RPC request has SOFTCONN set, and retries after a few seconds in the normal case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use TCP with the soft connect semantic for local rpcbind upcalls so the kernel can detect immediately if the local rpcbind daemon is not running. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
| | * | | SUNRPC: Use a cached RPC client and transport for rpcbind upcallsChuck Lever2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel's rpcbind client creates and deletes an rpc_clnt and its underlying transport socket for every upcall to the local rpcbind daemon. When starting a typical NFS server on IPv4 and IPv6, the NFS service itself does three upcalls (one per version) times two upcalls (one per transport) times two upcalls (one per address family), making 12, plus another one for the initial call to unregister previous NFS services. Starting the NLM service adds an additional 13 upcalls, for similar reasons. (Currently the NFS service doesn't start IPv6 listeners, but it will soon enough). Instead, let's create an rpc_clnt for rpcbind upcalls during the first local rpcbind query, and cache it. This saves the overhead of creating and destroying an rpc_clnt and a socket for every upcall. The new logic also prevents the kernel from attempting an RPCB_SET or RPCB_UNSET if it knows from the start that the local portmapper does not support rpcbind protocol version 4. This will cut down on the number of rpcbind upcalls in legacy environments. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
