* nfs-iostat.py: divide by zero with fresh mountKevin Constantine2010-06-221-0/+6
| | | | | | | | | | When an export is freshly mounted, /proc/self/mountstats displays age = 0. This causes nfs-iostat.py to divide by zero throwing an error. When we have age = 0, other stats are greater than 0, so we'll set age = 1 and print the relevant stats.

* libexport.a: Remove unused hostent-based DNS helper functionsChuck Lever2010-06-222-310/+16
| | | | | | | | | | | Clean up: Get rid of hostent-based DNS helper functions in libexport.a that have been replaced by addrinfo-based DNS helpers. None of the original code remains, so replace the copyright notice as well. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* libexport.a: Replace matchhostname()Chuck Lever2010-06-222-2/+78
| | | | | | | | | | | | | | | | | So that exportfs can eventually support IPv6 addresses, copy statd's getaddrinfo(3)-based matchhostname to exportfs, with adjustments for dealing with export wildcards and netgroups. Until exportfs has full IPv6 support, however, we want to ensure that IPv6 addresses continue to remain blocked in the address comparison code used by exportfs. At a later point we'll replace much of this with the generic functions in sockaddr.h. Since it contains special logic for handling wildcard and netgroups, this function is specialized for exportfs, and does not belong in one of the shared libraries.

* libexport.a: Make export_add() staticChuck Lever2010-06-222-5/+2

* libexport.a: Make export_read() return voidChuck Lever2010-06-222-3/+7

* mountd: Replace "struct hostent" with "struct addrinfo"Chuck Lever2010-06-228-212/+257
| | | | | | | | | | | | | | | | | | | 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.

* exportfs: Add a common exit label in exportfs()Chuck Lever2010-06-221-8/+6
| | | | | | | | | Clean up: Reduce code duplication by introducing a goto label for freeing hp and exiting. This will make replacing "struct hostent *" with "struct addrinfo *" more straightforward in this code.

* libexport.a: Add helpers to manage DNS lookupsChuck Lever2010-06-226-16/+382
| | | | | | | | | | | | | | | Introduce DNS query helpers based on getaddrinfo(3) and getnameinfo(3). These will eventually replace the existing hostent-based functions in support/export/hostname.c. Put some of these new helpers to immediate use, where convenient. As they are part of libexport.a, I've added the forward declarations for these new functions in exportfs.h rather than misc.h, where the hostent-based forward declarations are currently.

* Improve support for exporting btrfs subvolumesNeilBrown2010-06-221-29/+78
| | | | | | | | | | | | | | | | | | | If you export two subvolumes of a btrfs filesystem, they will both be given the same uuid so lookups will be confused. blkid cannot differentiate the two, so we must use the fsid from statfs64 to identify the filesystem. We cannot tell if blkid or statfs is best without knowing internal details of the filesystem in question, so we need to encode specific knowledge of btrfs in mountd. This is unfortunate. To ensure smooth handling of this and possible future changes in uuid generation, we add infrastructure for multiple different uuids to be recognised on old filehandles, but only the preferred on is used on new filehandles.

* mountd: Convert colons in IPv6 presentation addresses tosemicolonsChuck Lever2010-05-241-3/+39
| | | | | | | | | | | | | | The /var/lib/nfs/rmtab file delineates fields in each of its lines with a ":". The first field contains the IP address of a client, in presentation format. IPv6 presentation format addresses contain colons, which screws up the field delineation of rmtab. Use a simple simple scheme to convert the colons in incoming client names to some other character, and then convert them back when the rmtab file is read.

* Mountd listens on 2 different versions for NFSv2 (MOUNTv1 and MOUNTv2)NeilBrown2010-05-241-6/+8
| | | | | | | | | | | | | | | | | | | | | and one for NFSv3 (MOUNTv3) When --no-nfs-version requests an NFS version to be disabled, the code actually disabled the MOUNT version. This works is several cases, but requires --no-nfs-version 1 to completely disable NFSv2, which is wrong. So if we do disable 1, 2, and 3. mountd complain and won't run, it is not possible to run just v4 - i.e. not listening for MOUNT requests at all (as v4 doesn't need them). So change the handling of "--no-nfs-version 2" it disable MOUNTv1 as well as MOUNTv2, and allow mountd to continue running as long as one of NFSv2 NFSv3 NFSv4 is enabled.

* mountd/exportfs: Make m_addrlist field a nfs_sockaddrChuck Lever2010-05-055-17/+93
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* libexport.a: Clean up client_add()Chuck Lever2010-05-052-15/+12
| | | | | | | | | | | Clean up: client_add()'s current callers never set unknown m_type values, so the m_type check is unnecessary. All of client_add()'s callers are in the same source file where it is defined, so make it a static helper function.

| | | | | | | | | | | | | Clean up: Use malloc(3) instead of xmalloc() in client_lookup() and client_dup(), ensuring that a failed memory allocation here doesn't cause our process to exit suddenly.

| | | | | | | | | | | | Clean up: Replace xstrdup() with strdup(3) in client_init(), to prevent the process from exiting if the memory allocation fails. Note that both of client_init()'s callers set m_hostname equal to NULL before calling, thus the extra free(3) at the top of client_init() is unneeded.

* libexport.a: export_find() should handle address parsing errorsChuck Lever2010-04-161-0/+4
| | | | | | | | | | | | | | | An address mask parsing error can cause client_init(), and therefore client_dup(), to make our process exit suddenly. Soon we want to add more complex address parsing in client_init(), so we need this interface to be a little more robust. Since export_find() can return NULL in some cases, it can handle NULL returns from its subroutines if an address parsing error occurs, or if memory is exhausted.
