* nfsd: support NFS4_MAXMINOR up to the number an unsigned int can keepSteve Dickson2014-02-131-1/+2
| | | | | | | | | | | | | | | | | | | This implementation allows specifying NFS4 minor version numbers up to the number of bits available in int data type (typically 32 on Linux) This is based on an idea mentioned by J. Bruce Fields <bfields@fieldses.org> mentioned on the linux-nfs mailing list. I changed the data type back from an array to two bit fields, one for storing whether the minor version was specified on the command line and the second one for storing whether it was set or unset. This change was done to prevent blowing up the allocated stack space in an unnecessary fashion. Acked-by: J.

* nfsd: fix minorversion-choosing interfaceJ. Bruce Fields2014-01-071-1/+0
| | | | | | | | | | | | | | | | | | | | From: "J. Bruce Fields" <bfields@redhat.com> By unconditionally adding ?4.2 to the version string written to the kernel we make nfs-utils incompatible with pre-4.2-supporting kernels. Ditto for 4.1. This problem was introduced by 12a590f8d556c00a9502eeebaa763d906222d521 "rpc.nfsd: Allow v4.2 server support with the -V option", which also change nfsd to unconditionally pass ?4.2. Instead, just don't mention 4.1 or 4.2 unless the commandline has specifically requested that one or the other be turned on or off.

* nfs-utils: consolidate mydaemon() and release_parent() implementationsJeff Layton2013-11-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | We currently have 2 cut-and-paste versions of this code. One for idmapd and one for svcgssd.[1] The two are basically equivalent but there are some small differences, mostly related to how errors in that function are logged. svcgssd uses printerr() with a priority of 1, which only prints errors if -v was specified. That doesn't seem to be quite right. Daemonizing errors are necessarily fatal and should be logged as such. The one for idmapd uses err(), which always prints to stderr even though we have the xlog facility set up. Since both have xlog configured at this point, log the errors using xlog_err() instead. The only other significant difference I see is that the idmapd version will open "/" if it's unable to open "/dev/null". I believe that however was a holdover from an earlier version of that function that did not error out when we were unable to open a file descriptor. Since the function does that now, I don't believe we need that fallback anymore. [1]: technically, we have a third in statd too, but it's different enough that I don't want to touch it here.

* exportfs: exit with error code if there was any error (take 2).NeilBrown2013-11-052-3/+1
| | | | | | | | | | | | | | | | | exportfs currently exits with a non-zero error for some errors, but not for others. It does this by having various support routines set the global variable "export_errno". Change this to have 'xlog' set export_errno if an ERROR is reported. That way all errors will be caught. Note that the exit error code is changed from 22 (EINVAL) to the more traditional '1'. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Steve Dickson <steved@redhat.com>
* mount.nfs: dont pass options from configuration sections that are not relevantScott Mayhew2013-08-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The nfsmount.conf file has the following format: [ section "arg" ] tag = value conf_get_tag_list() currently doesn't check the arg field so we wind up getting all the options that fall under a particular section value, instead of just the ones that match the specific "arg" field. As a result, we wind up passing options to the mount syscall from sections that aren't even relevant to the mount operation that is being performed. For example, if we have three different server sections, and each section has an Nfsvers tag, then the string we pass to the mount syscall will have two extra occurrences of the nfsvers option. Each option should appear at most 4 times -- once for the system section, once for the server-specific section, once for the mount-specific section, and once for the command line mount options.

* nfs-utils: Increase the stdio file buffer size for procfs filesSean Finney2011-04-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, when writing to /proc/net/rpc/*/channel, if a cache line were larger than the default buffer size (likely 1024 bytes), mountd and svcgssd would split writes into a number of buffer-sized writes. Each of these writes would get an EINVAL error back from the kernel procfs handle (it expects line-oriented input and does not account for multiple/split writes), and no cache update would occur. When such behavior occurs, NFS clients depending on mountd to finish the cache operation would block/hang, or receive EPERM, depending on the context of the operation. This is likely to happen if a user is a member of a large (~100-200) number of groups. Instead, every fopen() on the procfs files in question is followed by a call to setvbuf(), using a per-file dedicated buffer of RPC_CHAN_BUF_SIZE length. Really, mountd should not be using stdio-style buffered file operations on files in /proc to begin with. A better solution would be to use internally managed buffers and calls to write() instead of these stdio calls, but that would be a more extensive change; so this is proposed as a quick and not-so-dirty fix in the meantime.

* libnfs.a: Fix API for getfh() & friendsChuck Lever2010-09-161-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Lever2010-09-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | 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.
