10	help
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.
15
16	  You may choose to use a user-space NFS server instead, in which
17	  case you can choose N here.
18
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
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.

35
36config 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
45config 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
68config NFSD_V4

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
86config NFSD_PNFS
87	bool "NFSv4.1 server support for Parallel NFS (pNFS)"
88	depends on NFSD_V4
89	help
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
92	  server.
93
94	  If unsure, say N.
95
96config NFSD_V4_SECURITY_LABEL
97	bool "Provide Security Label support for NFSv4 server"
98	depends on NFSD_V4 && SECURITY
99	help
100
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.
105
106	If you do not wish to enable fine-grained security labels SELinux or
107	Smack policies on NFSv4 files, say N.
108
109config NFSD_FAULT_INJECTION
110	bool "NFS server manual fault injection"
111	depends on NFSD_V4 && DEBUG_KERNEL && DEBUG_FS
112	help
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.
116
117	  If unsure, say N.
