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. 30 31 config NFSD_V2_ACL 32 bool 33 depends on NFSD 34 35 config 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 44 config 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 67 config NFSD_V4 68 bool "NFS server support for NFS version 4" 69 depends on NFSD && PROC_FS 70 select NFSD_V3 71 select FS_POSIX_ACL 72 select SUNRPC_GSS 73 select CRYPTO 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 85 config NFSD_PNFS 86 bool "NFSv4.1 server support for Parallel NFS (pNFS)" 87 depends on NFSD_V4 88 help 89 This option enables support for the parallel NFS features of the 90 minor version 1 of the NFSv4 protocol (RFC5661) in the kernel's NFS 91 server. 92 93 If unsure, say N. 94 95 config NFSD_V4_SECURITY_LABEL 96 bool "Provide Security Label support for NFSv4 server" 97 depends on NFSD_V4 && SECURITY 98 help 99 100 Say Y here if you want enable fine-grained security label attribute 101 support for NFS version 4. Security labels allow security modules like 102 SELinux and Smack to label files to facilitate enforcement of their policies. 103 Without this an NFSv4 mount will have the same label on each file. 104 105 If you do not wish to enable fine-grained security labels SELinux or 106 Smack policies on NFSv4 files, say N. 107 108 config NFSD_FAULT_INJECTION 109 bool "NFS server manual fault injection" 110 depends on NFSD_V4 && DEBUG_KERNEL 111 help 112 This option enables support for manually injecting faults 113 into the NFS server.
