9	help
10	  Choose Y here if you want to allow other computers to access
11	  files residing on this system using Sun's Network File System
12	  protocol.  To compile the NFS server support as a module,
13	  choose M here: the module will be called nfsd.
14
15	  You may choose to use a user-space NFS server instead, in which
16	  case you can choose N here.
17
18	  To export local file systems using NFS, you also need to install
19	  user space programs which can be found in the Linux nfs-utils
20	  package, available from http://linux-nfs.org/.  More detail about
21	  the Linux NFS server implementation is available via the
22	  exports(5) man page.
23
24	  Below you can choose which versions of the NFS protocol are
25	  available to clients mounting the NFS server on this system.
26	  Support for NFS version 2 (RFC 1094) is always available when
27	  CONFIG_NFSD is selected.
28
29	  If unsure, say N.

33	depends on NFSD
34
35config NFSD_V3
36	bool "NFS server support for NFS version 3"
37	depends on NFSD
38	help
39	  This option enables support in your system's NFS server for
40	  version 3 of the NFS protocol (RFC 1813).
41
42	  If unsure, say Y.
43
44config NFSD_V3_ACL
45	bool "NFS server support for the NFSv3 ACL protocol extension"
46	depends on NFSD_V3
47	select NFSD_V2_ACL
48	help
49	  Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
50	  never became an official part of the NFS version 3 protocol.
51	  This protocol extension allows applications on NFS clients to
52	  manipulate POSIX Access Control Lists on files residing on NFS
53	  servers.  NFS servers enforce POSIX ACLs on local files whether
54	  this protocol is available or not.
55
56	  This option enables support in your system's NFS server for the
57	  NFSv3 ACL protocol extension allowing NFS clients to manipulate
58	  POSIX ACLs on files exported by your system's NFS server.  NFS
59	  clients which support the Solaris NFSv3 ACL protocol can then
60	  access and modify ACLs on your NFS server.
61
62	  To store ACLs on your NFS server, you also need to enable ACL-
63	  related CONFIG options for your local file systems of choice.
64
65	  If unsure, say N.
66
67config NFSD_V4

74	select GRACE_PERIOD
75	help
76	  This option enables support in your system's NFS server for
77	  version 4 of the NFS protocol (RFC 3530).
78
79	  To export files using NFSv4, you need to install additional user
80	  space programs which can be found in the Linux nfs-utils package,
81	  available from http://linux-nfs.org/.
82
83	  If unsure, say N.
84
85config NFSD_V4_SECURITY_LABEL
86	bool "Provide Security Label support for NFSv4 server"
87	depends on NFSD_V4 && SECURITY
88	help
89
90	Say Y here if you want enable fine-grained security label attribute
91	support for NFS version 4.  Security labels allow security modules like
92	SELinux and Smack to label files to facilitate enforcement of their policies.
93	Without this an NFSv4 mount will have the same label on each file.
94
95	If you do not wish to enable fine-grained security labels SELinux or
96	Smack policies on NFSv4 files, say N.
97
98config NFSD_FAULT_INJECTION
99	bool "NFS server manual fault injection"
100	depends on NFSD_V4 && DEBUG_KERNEL
101	help
102	  This option enables support for manually injecting faults
103	  into the NFS server.  This is intended to be used for
104	  testing error recovery on the NFS client.
105
106	  If unsure, say N.
