2 tristate "NFS server support"
4 depends on FILE_LOCKING
8 select NFS_ACL_SUPPORT if NFSD_V2_ACL
11 Choose Y here if you want to allow other computers to access
12 files residing on this system using Sun's Network File System
13 protocol. To compile the NFS server support as a module,
14 choose M here: the module will be called nfsd.
16 You may choose to use a user-space NFS server instead, in which
17 case you can choose N here.
19 To export local file systems using NFS, you also need to install
20 user space programs which can be found in the Linux nfs-utils
21 package, available from http://linux-nfs.org/. More detail about
22 the Linux NFS server implementation is available via the
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.
37 bool "NFS server support for NFS version 3"
40 This option enables support in your system's NFS server for
41 version 3 of the NFS protocol (RFC 1813).
46 bool "NFS server support for the NFSv3 ACL protocol extension"
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.
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.
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.
69 bool "NFS server support for NFS version 4"
70 depends on NFSD && PROC_FS
77 This option enables support in your system's NFS server for
78 version 4 of the NFS protocol (RFC 3530).
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/.
87 bool "NFSv4.1 server support for Parallel NFS (pNFS)"
90 This option enables support for the parallel NFS features of the
91 minor version 1 of the NFSv4 protocol (RFC5661) in the kernel's NFS
96 config NFSD_V4_SECURITY_LABEL
97 bool "Provide Security Label support for NFSv4 server"
98 depends on NFSD_V4 && SECURITY
101 Say Y here if you want enable fine-grained security label attribute
102 support for NFS version 4. Security labels allow security modules like
103 SELinux and Smack to label files to facilitate enforcement of their policies.
104 Without this an NFSv4 mount will have the same label on each file.
106 If you do not wish to enable fine-grained security labels SELinux or
107 Smack policies on NFSv4 files, say N.
109 config NFSD_FAULT_INJECTION
110 bool "NFS server manual fault injection"
111 depends on NFSD_V4 && DEBUG_KERNEL && DEBUG_FS
113 This option enables support for manually injecting faults
114 into the NFS server. This is intended to be used for
115 testing error recovery on the NFS client.
