* nfs-utils: reverse order of librpcsecgss and libgssglue checksChuck Lever2009-04-151-5/+4
| | | | | | | | | | | | | The check that validates the version of librpcsecgss also needs to have libgssglue installed. Without libgssglue, ./configure complains that it can't find rpcsecgss, even though it's installed. It also turns out that the error message generated by pkg-config is more complete than the one we have in aclocal/rpcsec_vers.m4, so just let those PKG_CHECK_MODULES m4 macros use the default error message.

* nfs-utils: query for remote port using rpcbind instead of getaddrinfoJeff Layton2009-04-151-52/+86
| | | | | | | | | | | | | | | We already have the server's address from the upcall, so we don't really need to look it up again, and querying the local services DB for the port that the remote server is listening on is just plain wrong. Use rpcbind to set the port for the program and version that we were given in the upcall. The exception here is NFSv4. Since NFSv4 mounts are supposed to use a well-defined port then skip the rpcbind query for that and just set the port to the standard one (2049).

* nfs-utils: store the address given in the upcall for later useJeff Layton2009-04-152-17/+80
| | | | | | | | | | | | | | | | | The current upcall could be more efficient. We first convert the address to a hostname, and then later when we set up the RPC client, we do a hostname lookup to convert it back to an address. Begin to change this by keeping the address in the clnt_info that we get out of the upcall. Since a sockaddr has a port field, we can also eliminate the port from the clnt_info. Finally, switch to getnameinfo() instead of gethostbyaddr(). We'll need to use that call anyway when we add support for IPv6.

| | | | | | | | | | | | | Systems that are so old that they don't have getnameinfo() in glibc are probably also running kernels that are so old that they don't support gssapi upcalls anyway.

| | | | | | | | | | | | | | | | | | If qword_eol() fails while writing the context information, log an indication of the failure. This addresses at least one cause of the intermittent, and previously undiagnosed, problem of the server returning GSS_S_NO_CONTEXT when a context was seemingly successfully created and sent down to the kernel. In my case there was a mis-match between kernel and user-land configuration resulting in the proper kernel module not being loaded. Therefore the write of the context failed, but was not logged by svcgssd. When the kernel goes to find the resulting context, it was really not there and correctly returned GSS_S_NO_CONTEXT to the client.

* Mountd should use separate lockfilesBen Myers2009-04-036-21/+44
| | | | | | | | | | | | | | | | Mountd keeps file descriptors used for locks separate from those used for io and seems to assume that the lock will only be released on close of the file descriptor that was used with fcntl. Actually the lock is released when any file descriptor for that file is closed. When setexportent() is called after xflock() he closes and reopens the io file descriptor and defeats the lock. This patch fixes that by using a separate file for locking, cleaning them up when finished. Signed-off-by: Ben Myers <bpm@sgi.com> Signed-off-by: Steve Dickson <steved@redhat.com>

| | | | | | | | | | | | | There's no way for the caller of gssd_k5_err_msg to know whether to free the string it returns. It can call krb5_get_error_message which returns a string that must be freed via krb5_free_error_string. The other ways that it can return a string require that the memory not be freed.

* nfs-utils: Include legacy or TI-RPC headers, not bothChuck Lever2009-03-169-56/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Data type incompatibilities between the legacy RPC headers and the TI-RPC headers mean we can't use libtirpc with code that was compiled against the legacy RPC headers. The definition of rpcprog_t for example is "unsigned long" in the legacy library, but it's "uint32_t" for TI-RPC. On 32-bit systems, these types happen to have the same width, but on 64-bit systems they don't, making more complex data structures that use these types in fields ABI incompatible. Adopt a new strategy to deal with this issue. When --enable-tirpc is set, append "-I/usr/include/tirpc" to the compilation steps. This should cause the compiler to grab the tirpc/ headers instead of the legacy headers. Now, for TI-RPC builds, the TI-RPC legacy functions and the TI-RPC headers will be used. On legacy systems, the legacy headers and legacy glibc RPC implementation will be used. A new ./configure option is introduced to allow system integrators to use TI-RPC headers in some other location than /usr/include/tirpc. /usr/include/tirpc remains the default setting for this new option. The gssd implementation presents a few challenges, but it turns out the gssglue library is similar to the auth_gss pieces of TI-RPC. To avoid similar header incompatibility issues, gssd now uses libtirpc instead of libgssglue if --enable-tirpc is specified. There may be other issues to tackle with gssd, but for now, we just make sure it builds with --enable-tirpc. Note also: svc_getcaller() is a macro in both cases that points to a sockaddr field in the svc_req structure. The legacy version points to a sockaddr_in type field, but the TI-RPC version points to a sockaddr_in6 type field. rpc.mountd unconditionally casts the result of svc_getcaller() to a sockaddr_in *. This should be OK for TI-RPC as well, since rpc.mountd still uses legacy RPC calls (provided by glibc, or emulated by TI-RPC) to set up its listeners, and therefore rpc.mountd callers will always be from AF_INET addresses for now.

* mount.nfs: squelch compiler warning for TI-RPC buildsChuck Lever2009-03-051-2/+3
| | | | | | | | | | | | | | | | | | | | | | The printf format string in nfs_pp_debug() assumes the @program and @version arguments are unsigned long, because the legacy RPC headers define both rpcprog_t and rpcvers_t as unsigned long types. However, the TI-RPC headers define both types as uint32_t, which requires a different printf format type. If we replace the legacy headers with TI-RPC headers, this type mismatch generates compiler warnings that are nothing but noise. We are about to provide a switch at ./configure time to allow the use of either the legacy RPC headers or the TI-RPC headers, so we need a printf format that works in both cases. To squelch the compiler warnings that occur when using the TI-RPC headers, cast both arguments in the fprintf statement to the widest of the two types ("unsigned long" or "uint32_t").
