* nfs-utils: add and use nfs_authsys_createJeff Layton2010-03-011-1/+7
| | | | | | | | | | | | | | | | | | The current mount, umount and showmount code uses authunix_create_default to get an auth handle. The one provided by glibc returned a truncated list of groups when there were more than 16 groups. libtirpc however currently does an abort() in this case, which causes the program to crash and dump core. nfs-utils just uses these auth handles for the MNT protocol, so the group list doesn't make a lot of difference here. Add a new function that creates an auth handle with a supplemental gids list that consists only of the primary gid. Have nfs-utils use that function anywhere that it currently uses authunix_create_default. Also, have the caller properly check for a NULL return from that function.

* showmount: Try the highest mount version then fall back to lower onesSteve Dickson2010-01-111-7/+30
| | | | | | | | | | Showmount should try the highest mount version first then fall back to the lower ones when the server returns a RPC_PROGVERSMISMATCH error. The idea being not using the lower mount versions will begin the process of moving away from NFSv2 support.

* showmount command: remove legacy RPC logicChuck Lever2009-03-041-141/+0
| | | | | | | | | Turns out both legacy RPC and TI-RPC have a clnt_create(3) API. So there's really no need to keep the old open-coded transport logic around. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* showmount command: Quiesce warning when TI-RPC is disabledChuck Lever2009-01-071-7/+7
| | | | | | | | | | Make sure nfs_sm_pgmtbl is not compiled if TI-RPC functions are not available. This quiesces the following compiler warning: showmount.c:53: warning: nfs_sm_pgmtbl defined but not used Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* showmount command: support querying IPv6 serversChuck Lever2008-11-251-0/+36
| | | | | | | | | | Introduce a version of nfs_get_mount_client() that supports AF_INET6 and AF_INET server addresses. If the TI-RPC library is not available when the showmount command is built, fall back to the legacy RPC user-space API.

* showmount command: move logic to acquire RPC client handle out of main()Chuck Lever2008-11-251-52/+64
| | | | | | | | | | In preparation to support IPv6 in the showmount command, extract the logic that parses/acquires the target hostname and converts it into an RPC client handle to contact the remote mountd service, and move it into its own function.

* showmount command: Remove unused local getport() implementationChuck Lever2008-11-251-105/+0
| | | | | | | | Clean up: remove showmount.c's local getport() implementation, now that the showmount command uses the shared one. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* showmount command: call nfs_getport instead of local getportChuck Lever2008-11-251-6/+8
| | | | | | | | | | Have the showmount command invoke the shared nfs_getport() function instead of its own local version. This gives the showmount command immediate support for querying via rpcbindv3/v4 in addition to portmapper, and sets the stage for AF_INET6 support in showmount.

* showmount: destroy RPC client when finishedChuck Lever2008-09-261-0/+4
| | | | | | | | | Clean up: call clnt_destroy() in the showmount command as needed to destroy the RPC client properly (and close the associated socket) before the program exits. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* showmount command: clean up error returns from connect_nb()Chuck Lever2008-09-261-10/+12
| | | | | | | | | | | | | Clean up connect_nb() in the showmount command. Sometimes it returns -1 on error, and sometimes a negative errno. On error, it should always return one of these or the other, not both. Similar functions in other parts of nfs-utils return -1 on error, and set errno; so let's do that here too.

* showmount issuesMartin Leisner2008-07-251-2/+4
| | | | | | | | The connect_nb() routne returns zero for success and a negative value for failure which was not being interpreted correctly by the getport() routine. This patch fixes that problem. Signed-off-by: Steve Dickson <steved@redhat.com>

* update manpages for showmount and mountdJeff Layton2007-05-081-2/+4
| | | | | | | | This patch updates the manpages for showmount and mountd. It adds a description of the new mountd -r option, and a caveat about the unreliability of showmount -a. Signed-off-by: Jeff Layton <jlayton@redhat.com>
* Fix showmount bugs.Neil Brown2007-02-221-3/+6
| | | | | | | When doing a nonblocked connect, we need to select for 'write', not 'read'. Also, when a tcp socket has been connected, we should use clnttcp_create to make a tcp client, not clntudp_bufcreate !!
* Remove explicit path names from man page for showmount and lockd.Neil Brown2007-02-051-1/+1
| | | | | Just like statd, the path isn't needs in the man page and different distros install it in different places.
* Various minor manpage fixes.Steinar H. Gunderson2007-02-051-1/+1
| | | | | | | | | | This mostly takes care of the difference between - and \-; in man pages, the former is hyphen (which indicates, among others, that a line might be split at that point), while the latter is a dash. For options, the latter is correct. There's also one minor grammatical fix.
* Reduce showmount timeouts.Ian Kent2006-12-201-8/+201
| | | | | | | | | | | | | | | | | | | Showmount itself tries to use a short timeout but the RPC clnttcp_create and clntudp_create calls will call portmap internally to get the port to use if it is set to 0 in the passed address structure. The above calls then use the internal timeouts, basically 60 seconds, which slows things down. Also the for tcp a blocking connect is used which can take quite a while to timeout as well. showmount tries tcp then udp so a fail can go through several lengthy waits before failing. I've grabbed some of the autofs code and put together a patch to allow specification of the timeouts for the portmap getport and to implement a non-blocking connect.
