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. 31 32 config NFSD_V2_ACL 33 bool 34 depends on NFSD 35 36 config 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 45 config 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 68 config NFSD_V4 69 bool "NFS server support for NFS version 4" 70 depends on NFSD && PROC_FS 71 select NFSD_V3 72 select FS_POSIX_ACL 73 select SUNRPC_GSS 74 select CRYPTO 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 86 config 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 96 config 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. 108 109 config 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.
