More detail about 22 the Linux NFS server implementation is available via the 23 exports(5) man page. 24 25 Below you can choose which versions of the NFS protocol are 26 available to clients mounting the NFS server on this system. 27 Support for NFS version 2 (RFC 1094) is always available when 28 CONFIG_NFSD is selected. 29 30 If unsure, say N. 31 32 config NFSD_V2_ACL 33 bool 34 depends on NFSD 35 36 config NFSD_V3 37 bool "NFS server support for NFS version 3" 38 depends on NFSD 39 help 40 This option enables support in your system's NFS server for 41 version 3 of the NFS protocol (RFC 1813). 42 43 If unsure, say Y. 44 45 config NFSD_V3_ACL 46 bool "NFS server support for the NFSv3 ACL protocol extension" 47 depends on NFSD_V3 48 select NFSD_V2_ACL 49 help 50 Solaris NFS servers support an auxiliary NFSv3 ACL protocol that 51 never became an official part of the NFS version 3 protocol. 52 This protocol extension allows applications on NFS clients to 53 manipulate POSIX Access Control Lists on files residing on NFS 54 servers. NFS servers enforce POSIX ACLs on local files whether 55 this protocol is available or not. 56 57 This option enables support in your system's NFS server for the 58 NFSv3 ACL protocol extension allowing NFS clients to manipulate 59 POSIX ACLs on files exported by your system's NFS server. NFS 60 clients which support the Solaris NFSv3 ACL protocol can then 61 access and modify ACLs on your NFS server. 62 63 To store ACLs on your NFS server, you also need to enable ACL- 64 related CONFIG options for your local file systems of choice. 65 66 If unsure, say N. 67 68 config NFSD_V4 69 bool "NFS server support for NFS version 4" 70 depends on NFSD && PROC_FS 71 select NFSD_V3 72 select FS_POSIX_ACL 73 select SUNRPC_GSS 74 select CRYPTO 75 select GRACE_PERIOD 76 help 77 This option enables support in your system's NFS server for 78 version 4 of the NFS protocol (RFC 3530). 79 80 To export files using NFSv4, you need to install additional user 81 space programs which can be found in the Linux nfs-utils package, 82 available from http://linux-nfs.org/. 83 84 If unsure, say N. 85 86 config NFSD_PNFS 87 bool 88 89 config NFSD_BLOCKLAYOUT 90 bool "NFSv4.1 server support for pNFS block layouts" 91 depends on NFSD_V4 && BLOCK 92 select NFSD_PNFS 93 select EXPORTFS_BLOCK_OPS 94 help 95 This option enables support for the exporting pNFS block layouts 96 in the kernel's NFS server.
