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