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/.
89 config NFSD_BLOCKLAYOUT
90 bool "NFSv4.1 server support for pNFS block layouts"
91 depends on NFSD_V4 && BLOCK
93 select EXPORTFS_BLOCK_OPS
95 This option enables support for the exporting pNFS block layouts
96 in the kernel's NFS server. The pNFS block layout enables NFS
97 clients to directly perform I/O to block devices accesible to both
98 the server and the clients. See RFC 5663 for more details.
102 config NFSD_SCSILAYOUT
103 bool "NFSv4.1 server support for pNFS SCSI layouts"
104 depends on NFSD_V4 && BLOCK
106 select EXPORTFS_BLOCK_OPS
107 select BLK_SCSI_REQUEST
109 This option enables support for the exporting pNFS SCSI layouts
110 in the kernel's NFS server. The pNFS SCSI layout enables NFS
111 clients to directly perform I/O to SCSI devices accesible to both
112 the server and the clients. See draft-ietf-nfsv4-scsi-layout for
117 config NFSD_FLEXFILELAYOUT
118 bool "NFSv4.1 server support for pNFS Flex File layouts"
122 This option enables support for the exporting pNFS Flex File
123 layouts in the kernel's NFS server. The pNFS Flex File layout
124 enables NFS clients to directly perform I/O to NFSv3 devices
125 accesible to both the server and the clients. See
126 draft-ietf-nfsv4-flex-files for more details.
128 Warning, this server implements the bare minimum functionality
129 to be a flex file server - it is for testing the client,
130 not for use in production.
134 config NFSD_V4_SECURITY_LABEL
135 bool "Provide Security Label support for NFSv4 server"
136 depends on NFSD_V4 && SECURITY
139 Say Y here if you want enable fine-grained security label attribute
140 support for NFS version 4. Security labels allow security modules like
141 SELinux and Smack to label files to facilitate enforcement of their policies.
142 Without this an NFSv4 mount will have the same label on each file.
144 If you do not wish to enable fine-grained security labels SELinux or
145 Smack policies on NFSv4 files, say N.
147 config NFSD_FAULT_INJECTION
148 bool "NFS server manual fault injection"
149 depends on NFSD_V4 && DEBUG_KERNEL && DEBUG_FS
151 This option enables support for manually injecting faults
152 into the NFS server. This is intended to be used for
153 testing error recovery on the NFS client.
