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.

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.

Clean up: remove showmount.c's local getport() implementation, now that
the showmount command uses the shared one.

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.

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.

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.

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.

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.

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 !!
|
| |
|
|
|
| |
Just like statd, the path isn't needs in the man page and different
distros install it in different places.

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.

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.
