* export: Ensure that we free struct exportent->e_uuidTrond Myklebust2010-10-142-0/+3
| | | | | | | | | | | | | | | | | | Currently, the exportent->e_uuid is initialised in support/nfs/exports.c:parseopts(), but it is never freed. Also ensure that exportent->e_uuid is duplicated correctly in dupexportent(). Adjusted to account for the new export_free() helper. Also, e_uuid points to memory that is always allocated with strdup(3), not with xstrdup(). Thus it must be freed via free(3) and not via xfree().

* libnfs.a: Allow multiple RPC listeners to share listener port numberChuck Lever2010-10-141-6/+246
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, when "-p" is not specified on the mountd command line, the TI-RPC library chooses random port numbers for each listener. If a port number _is_ specified on the command line, all the listeners will get the same port number, so SO_REUSEADDR needs to be set on each socket. Thus we can't let TI-RPC create the listener sockets for us in this case; we must create them ourselves and then set SO_REUSEADDR (and other socket options) by hand. Different versions of the same RPC program have to share the same listener and SVCXPRT, so we have to cache xprts we create, and re-use them when additional requests for registration come from the application. Though it doesn't look like it, this fix was "copied" from the legacy rpc_init() function. It's more complicated for TI-RPC, of course, since a TI-RPC application can set up listeners with a nearly arbitrary number of address families and socket types, not just the two listeners that legacy RPC applications can set up (one for AF_INET UDP and one for AF_INET TCP).

| | | | | | | | | | | | If --enable-ipv6 is specified when building nfs-utils, libexport's host_foo() helpers can now return both IPv4 and IPv6 addresses.

* libnfs.a: Fix API for getfh() & friendsChuck Lever2010-09-162-9/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is more of a clean-up than a behavioral change. POSIX requires that a "struct sockaddr" is the same size as a "struct sockaddr_in". Therefore, a variable or field of type "struct sockaddr" cannot contain an AF_INET6 address. However, "struct sockaddr *" is often used to reference a generic (ie non-address family specific) socket address, generating some confusion about this. The nfsctl_arg struct uses a struct sockaddr (not a pointer) to pass the client's IP address to the kernel. This means the legacy nfsctl() kernel API can never support IPv6. Fortunately for us, this legacy interface was replaced by a text-based cache interface a few years back. We don't need to support non-AF_INET addresses here. The getfh() functions in nfs-utils provide a handy C API for the kernel's nfsctl interface. The getfh() functions still take a struct sockaddr *, though, and that can imply that a non-IPv4 address can be passed via this API. To make it abundantly clear that only IPv4 addresses can be used with this interface, change the synopses of getfh() and friends to take a struct sockaddr_in * instead of a struct sockaddr * . This makes these functions conform with other places in mountd and exportfs that already grok the difference between a struct sockaddr and a struct sockaddr_in. While we're here... Introduce some nice documenting comments for the get_fh() functions, and... Since mountd will support IPv6 in the near future, assert that the family of client addresses passed to this API is indeed AF_INET, in order to prevent non-AF_INET addresses from ever being passed to the legacy nfsctl() interface.

* getport: Recognize "rdma" and "rdma6" netidChuck Lever2010-09-092-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | The mount.nfs command must recognize the values of "rdma" and "rdma6" with the "proto=" mount option. Typically the mount.nfs command relies on libtirpc or getprotobyname(3) to recognize netids and translate them to protocol numbers. RFCs 5665 and 5666 define the "rdma" and "rdma6" netids. IANA defines a specific port number for NFS over RDMA (20049), but has not provided a protocol name and number for RDMA transports, and is not expected to. The best we can do is translate these by hand, as needed, to get RDMA mount requests to the kernel without erroring out. Only the forward translation is needed until such time that "rdma" and "rdma6" start to appear in rpcbind registries. For now, the version and transport negotiation logic is skipped, avoiding rpcbind queries for RDMA mounts. Note: As of kernel 2.6.36, the kernel's NFS over RDMA transport capability does not support IPv6. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* libexport.a: Refactor init_netmask()Chuck Lever2010-09-091-57/+106
| | | | | | | | | | | | | | | Instead of a single function that can handle both AF_INET and AF_INET6 addresses, two separate functions might be cleaner. The original plan was to keep code redundancy at a minimum, but the resulting code was cumbersome at best. I think I've traded a little extra code for something that will be much easier to read, understand, and maintain. I've also eliminated the "#if / #endif" instances inside the functions.

* libexport.a: IPv6 support for client_init_subnet()Chuck Lever2010-08-311-0/+32
| | | | | | | | | | | | | | | To parse and store an IPv6 host or subnet address, init_netmask() needs to handle 128 bit subnet masks. Unfortunately what once was a pretty simple little function has grown much larger. This logic must now not only parse IPv6 addresses correctly, but must also distinguish between IPv4 and IPv6. To avoid code duplication, I'm "bending" the cardinal rule of not using "#ifdef" inside functions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* libexport.a: Prepare init_subnetwork() for IPv6 supportChuck Lever2010-08-311-22/+59
| | | | | | | | | | | | | | | | Retire the slash32 logic in inet_netmask() in favor of a more generic netmask parser that can support IPv6 addresses. If an invalid IP address string is given to inet_addr(3), it returns INADDR_NONE, which is actually a "valid" address (255.255.255.255). We're none the wiser to the substitution until something breaks later. This patch provides better sanity checking of the parsed address, now that such an error can be reported to client_init()'s callers. We can also check the prefixlen value a little more carefully as well. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>

* libexport: Fix IP address check in check_netgroup()Chuck Lever2010-08-241-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | Neil Brown reports that recent changes to replace gethostby{addr,name}(3) with get{addr,info}name(3) may have inadvertently broken netgroup support. There used to be a gethostbyaddr(3) call in the third paragraph in check_netgroup(). The reason for that gethostbyaddr(3) call was that the first innetgr(3) call has already confirmed that hname is not a member of the netgroup. We also need to confirm that, if hname happens to be an IP address, the hostname bound to that IP address is not a member of the netgroup, either. Fix this by restoring appropriate address to hostname mapping of hname before retrying the innetgr(3) call. See http://marc.info/?l=linux-nfs&m=128084830214653&w=2 .

| | | | | | | | | | | | | | | | | | | struct hostent can store either IPv4 or IPv6 addresses, but it can't store both address families concurrently for the same host. Neither can hostent deal with parts of socket addresses that are outside of the sin{,6}_addr field. Replace the use of "struct hostent" everywhere in libexport.a, mountd, and exportfs with "struct addrinfo". This is a large change, but there are so many strong dependencies on struct hostent that this can't easily be broken into smaller pieces. One benefit of this change is that hostent_dup() is no longer required, since the results of getaddrinfo(3) are already dynamically allocated.

| | | | | | | | | | | | | | | | | | | | | | | | To store non-AF_INET addresses in the nfs_client structure, we need to use more than in_addr for the m_addrlist field. Make m_addrlist larger, then add a few helper functions to handle type casting and array indexing cleanly. We could treat the nfs_client address list as if all the addresses in the list were the same family. This might work for MCL_SUBNETWORK type nfs_clients. However, during the transition to IPv6, most hosts will have at least one IPv4 and one IPv6 address. For MCL_FQDN, I think we need to have the ability to store addresses from both families in one nfs_client. Additionally, IPv6 scope IDs are not part of struct sin6_addr. To support link-local IPv6 addresses and the like, a scope ID must be stored. Thus, each slot in the address list needs to be capable of storing an entire socket address, and not simply the network address part.
