Overview: ------------ The Network File System Version 4 (NFSv4) is a distributed file system similar to previous versions of NFS in its straightforward design, and independence of transport protocols and operating systems for file access in a heterogeneous network. Unlike earlier versions of NFS, the new protocol integrates file locking, strong security, Compound RPCs (combining relevant operations), and delegation capabilities to enhance client performance for narrow data sharing applications on high-bandwidth networks. NFSv4 implementations are backward compatible with NFSv2 and NFSv3. Note: NFSv4 ACLs and krb5p (Kerberos Privacy) are currently not supported 1.1 The Purpose of this document ________________________________ This document is intended as a step-by-step guide to setup NFSv4 on openSUSE 12. It discusses NFSv4 server and client configuration. 2. Quickstart ------------- For NFSv4 server: 1) /etc/exports does not require any special entries to work with NFSv4. Earlier SUSE releases required 'fsid=0' on precisely one entry, and 'bind=' annotations on others. This is no longer required and should be removed. It is still supported, so there is no need to change /etc/exports when upgrading to openSUSE 12. 2) Edit /etc/idmapd.conf to modify the default "Domain" to contain your DNS domain name. 3) Execute the following commands to start idmapd and nfsserver #/etc/init.d/idmapd start #/etc/init.d/nfsserver start For NFSv4 client: 1) Edit /etc/idmapd.conf to modify the default "Domain" to contain your DNS domain name. 2) Execute the following command to start idmapd. #/etc/init.d/idmapd start 3) Mount the exported file system using the following command: #mount -t nfs4 <servername>:/ <mntpath> Observe that only "/" is given instead of the actual exported path name. 3. Idmapd Configuration on client and server -------------------------------------------- idmapd.conf - configuration file for idmapd (idmapping daemon), which does NFSV4<=>name mapping. Here dns domain (Domain) name has to be configured in both client and server. Sample Configuration file: ========================================================================== [General] Verbosity = 0 Pipefs-Directory = /var/lib/nfs/rpc_pipefs Domain = mydomain.com [Mapping] Nobody-User = nobody Nobody-Group = nobody ========================================================================== 4. Setting up NFSv4 server and client ------------------------------------- 4.1 Configuring Server ___________________________ There are three main configuration files you will need to edit to set up an NFSv4 server: /etc/sysconfig/nfs and /etc/idmapd.conf. we will describe the first here as idmapd.conf is done in previous section. 4.1.1 /etc/sysconfig/nfs ========================= /etc/sysconfig/nfs is another NFS server configuration file. Here the number of kernel threads, NFSv4 support and GSS security (kerberos) for NFS can be configured (kerberos set up is explained in Section 5.) 4.2 Starting services on server and client __________________________________________ We need to start idmapd and nfsserver on the NFSv4 server. #/etc/init.d/idmapd start #/etc/init.d/nfsserver start and start idmapd alone on the client. If the machines that are being used as client and server are just meant for that, the daemons can be enabled during bootup as shown below. Use insserv to do this #insserv -d idmapd #insserv -d nfsserver and idmapd alone on the client. 4.3 Mounting remote exported directories ________________________________________ One main difference between previous versions of NFS and NFSv4 is the way in which mount is invoked. With regard to the pseudofilesystem concept sketched above, mount is done as follows: #mount -t nfs4 <servername>:/ <mntpath> Observe that only '/' is given after the servername. 5. Setting up kerberized NFSv4 server and client ------------------------------------------------ 5.1 Prerequisites _________________ o Key Distribution Center (KDC) must already be set up on the network. o krb5-1.4.x must be installed on both NFS server and NFS client. o krb5-client-1.4.x must be installed on both NFS server and NFS client. o NFS server, client and the KDC server must have their time synchronized. o NFS_SECURITY_GSS has to be set to "yes" in /etc/sysconfig/nfs in both server and client. 5.2 Configuring Kerberized NFSv4 server and client __________________________________________________ All the following configuration steps except 5.2.4 are for both NFSv4 client and server. 5.2.1 Configure kerberos ======================== Edit krb5.conf. Sample configuration ========================================================================== [libdefaults] default_realm = MYDOMAIN.COM dns_lookup_realm = true dns_lookup_kdc = true [realms] MYDOMAIN.COM = { kdc = kdcserver.mydomain.com admin_server = adminserver.mydomain.com default_domain = mydomain.com } [domain_realm] mydomain.com = MYDOMAIN.COM .mydomain.com = MYDOMAIN.COM [logging] kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmin.log default = FILE:/var/log/krb5lib.log ========================================================================== Replace MYDOMAIN.COM with your REALM, kdcserver.mydomain.com with your KDC server, adminserver.mydomain.com with your Admin server & mydomain.com with your DNS domain name. 5.2.2 Create machine credentials ================================ This means creating a Kerberos V5 principal/instance name of the form nfs/<hostname>@REALM, and either adding a key for this principal to an existing /etc/krb5.keytab or creating an /etc/krb5.keytab. Note: only the encryption type of des-cbc-crc is functional so far in the kernel, so add only this type of key. kadmin: addprinc -e des-cbc-crc:normal nfs/<hostname>@REALM kadmin: ktadd -e des-cbc-crc:normal -k /etc/krb5.keytab nfs/<hostname>@REALM 5.2.3 Configure /etc/gssapi_mech.conf ===================================== This configuration file determines which GSS-API mechanisms the gssd code should use. Usually no need to modify this file in 32 bit machines because the libraries are installed in /usr/lib. Note: In case of 64 bit machines this has to be modified to /usr/lib64. This is a workaround and will be fixed later. Sample configuration ========================================================================== # GSSAPI Mechanism Definitions # # This configuration file determines which GSS-API mechanisms # the gssd code should use # # NOTE: # The initialization function "mechglue_internal_krb5_init" # is used for the MIT krb5 gssapi mechanism. This special # function name indicates that an internal function should # be used to determine the entry points for the MIT gssapi # mechanism functions. # # library initialization function # ================================ ========================== # The MIT K5 gssapi library, use special function for initialization. /usr/lib/libgssapi_krb5.so mechglue_internal_krb5_init # # The SPKM3 gssapi library function. Use the function spkm3_gss_initialize. # /usr/local/gss_mechs/spkm/spkm3/libgssapi_spkm3.so spkm3_gss_initialize ========================================================================== 5.2.4 /etc/exports entries for a kerberized server ================================================== Typical entries for kerberos security mode looks like these: /export gss/krb5(rw,insecure,no_subtree_check,sync,no_root_squash) /export gss/krb5i(rw,insecure,no_subtree_check,sync,no_root_squash) Note: i) option 'insecure' - The insecure option in this entry also allows clients with NFS implementations that don't use a reserved port for NFS. So it is advisable *NOT* to use this option unless you have a kerberised set up or you know what you are doing. 5.3 Starting the services on server and client ______________________________________________ On NFSv4 server, svcgssd needs to be started too. So, #/etc/init.d/idmapd start #/etc/init.d/svcgssd start #/etc/init.d/nfsserver start On NFSv4 client, gssd needs to be started too. So, #/etc/init.d/idmapd start #/etc/init.d/gssd start Or To avoid starting manually, enable service during bootup using insserv as mentioned in 4.2 5.4 Mounting exported directories with kerberos _______________________________________________ To mount a filesystem using krb5, provide the "-osec=krb5" option to mount. #mount -tnfs4 -osec=<secmode> nfsserver:/ /mntpoint <secmode> can be krb5(Autentication) or krb5i (Integrity). 5.5 A known issue using NFSv4 with kerberos ___________________________________________ Even if "no_root_squash" option is used, while exporting a filesystem at the server, root on the client gets a "Permission denied" error when creating files on the mount point. This is because there is no proper mapping between root and the GSSAuthName. Note: Trying to set 777 permission is not correct as it is not secure. Also, any file created on the mountpoint will have "nobody" as owner. There is a work around for this if both NFS server and client use ldap_umich methods to authenticate. If the idmapd on both server and client is configured to use ldap_umich modules then having GSSAuthName () parameter map to root user, on the ldap server will solve this problem. A proper fix for this issue is being worked upon. 6. Troubleshooting ------------------- 6.1 Checklist to ensure NFSV4 is up and running _______________________________________________ 1. ps -ef | grep nfsd ps -ef | grep idmapd ps -ef | grep svcgssd to check server side daemons are up and running. 2. ps -ef | grep idmapd ps -ef | grep gssd to check client side daemons are up and running 3. rpcinfo -p to check all registered RPC programs (nfs, portmapper, mountd) & versions 4. Check firewall is enabled on server/client from YAST. Yast -> Security and Users -> Firewall. Make sure NFS service is enabled. 5. showmount -e <server name> to check mount information on NFS server 6. If users are not mapped properly check whether idmapd is running in both server & client and dns domain name is properly configured. 7. If you unable to mount, check for the correctness of the exports file entry. 6.2 Check list to ensure kerberos is working properly _____________________________________________________ There are many reasons this could be failing. 1. Verify that rpc.gssd is running on the client and rpc.svcgssd is running on the server. 2. Verify that your hostnames are correct. The hostname command should return a fully-qualified hostname that has a correct DNS reverse-mapping (either through DNS or the /etc/hosts file). 3. Verify there is a keytab entry for nfs/<hostname>@REALM in your keytab file (/etc/krb5.keytab). 4. Verify your Kerberos configuration file has the proper mapping from the DNS hostname to the correct realm. The [domain_realm] section of the /etc/krb5.conf needs to have a mapping from the DNS domain to the correct REALM. For example, if your nfs server's hostname is 'foo.abc.org' and your Kerberos realm name is 'ALPHABET.ORG', then you need an entry like the following in /etc/krb5.conf on the nfs client machine: [domain_realm] .abc.org = ALPHABET.ORG 5. Verify whether your ticket is not expired or not on the client using klist. If it is expired renew using kinit. This must be checked when you find "I/O Error" or "Permission denied" while doing file operations. ++++++ fw-client ++++++ ## Description: Firewall Configuration for NFS client. # # Only the variables TCP, UDP, RPC, IP and BROADCAST are allowed. # More may be supported in the future. # # For a more detailed description of the individual variables see # the comments for FW_SERVICES_*_EXT in /etc/sysconfig/SuSEfirewall2 # ## Name: NFS Client ## Description: Opens ports for NFS client to allow connection to an NFS server. # space separated list of allowed TCP ports TCP="" # space separated list of allowed UDP ports UDP="" # space separated list of allowed RPC services RPC="portmap status nlockmgr" # space separated list of allowed IP protocols IP="" # space separated list of allowed UDP broadcast ports BROADCAST="" ++++++ fw-server ++++++ ## Description: Firewall Configuration for NFS kernel server. # # Only the variables TCP, UDP, RPC, IP and BROADCAST are allowed. # More may be supported in the future. # # For a more detailed description of the individual variables see # the comments for FW_SERVICES_*_EXT in /etc/sysconfig/SuSEfirewall2 # ## Name: NFS Server Service ## Description: Opens ports for NFS to allow other hosts to connect. # space separated list of allowed TCP ports TCP="" # space separated list of allowed UDP ports UDP="" # space separated list of allowed RPC services RPC="portmap status nlockmgr mountd nfs nfs_acl" # space separated list of allowed IP protocols IP="" # space separated list of allowed UDP broadcast ports BROADCAST="" ++++++ gssd-mount-hang-fix ++++++ From: Neil Brown Date: Thu, 14 Nov 2013 11:50:38 +1100 Subject: [PATCH] gssd: always reply to rpc-pipe requests from kernel. References: bnc#833543 Sometimes gssd will open a new rpc-pipe but never read requests from it or reply to them. This causes the kernel to wait forever for a reply. In particular, if a filesystem is mounted by IP, and the IP has no hostname recorded in /etc/hosts or DNS, then gssd will not listen to requests and the mount will hang indefinitely. The comment in process_clnt_dir() for the "fail_keep_client:" branch suggests that it is for the case where we couldn't open some subdirectories. However it is currently also taken if reverse DNS lookup fails (as well as some other lookup failures). Those failures should not be treated the same as failure-to-open directories. So this patch causes a failure from read_service_info() to *not* be reported by process_clnt_dir_files. This ensures that insert_clnt_poll() will be called and requests will be handled. In handle_gssd_upcall, the current error path (taken when the mech is not "krb5") does not reply to the upcall. This is wrong. A reply is always appropriate. The only replies which aren't treated as transient errors are EACCES and EKEYEXPIRED, so we return the former. If read_service_info() fails then ->servicename will be NULL which will cause process_krb5_upcall() (quite reasonably) to become confused. So in that case we don't even try to process the up-call but just reply with EACCES. As clp->servicename==NULL is no longer treated as fatal, it is not appropraite to use it to test if read_service_info() has been already called on a client. Instread test clp->prog. Finally, the error path of read_service_info() will close 'fd' if it isn't -1, so when we close it, we should set fd to -1.

commit 5604b35a61e22930873ffc4e9971002f578e7978 nfs-utils: Increase the stdio file buffer size for procfs files changed writes to some sysfs files to be line buffered (_IOLBF) where they weren't before. While this probably makes sense, it introduced a bug. With fully buffered streams, you don't expect to get an error until you call fflush(). With line buffered streams you can get the error from fprintf() et al. qword_eol() only tests the return from fflush, not from fprintf. Consequently errors were not noticed. One result of this is that if you export, with crossmnt, a filesystem underneath which are mounted non-exportable filesystems (e.g. /proc) then an 'ls -l' on the client will block indefinitely waiting for a meaningful 'yes' or 'no' from the server, but will never get one. This patch changes qword_eol to test both fprintf and fflush.

From 6eba4e22ce2b10bcfb19fbb253f7e235afbaa406 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 19 Apr 2013 13:09:27 -0400 Subject: [PATCH] mountd: fix exporting of "/" with sec= setting.

Commit 91bb95f2689e84856ecdf6fac365489d36709cf9 4set_root: force "fsid=0" for all exports of '/' set NFSEXP_FSID for the export of "/" if nothing else had any fsid set, however it didn't also set the flag for all security flavours. So the kernel complains that the flags on the security flavours don't match and it rejects the export. So call fix_pseudoflavor_flags() in write_secinfo() to make sure that any fiddling that has been done to e_flags gets copied to e_secinfo.

GSSD_OPTIONS="" ++++++ udp-fallback-fix.patch ++++++ From: NeilBrown Subject: Fix fallback from tcp to udp References: bnc#863749 Protocol negotiation in mount.nfs does not correctly negotiate with a server which only support NFSv3 and UDP. When mount.nfs attempts an NFSv4 mount and fails with ECONNREFUSED it does not fall back to NFSv3, as this is not recognised as a "does not support NFSv4" error. However ECONNREFUSED is a clear indication that the server doesn't support TCP, and ipso facto does not support NFSv4. So ECONNREFUSED should trigger a fallback from v4 to v2/3. Once we allow that error, NFSv3 is attempted and mount.nfs talks to rpcbind and discovers that UDP should be used for v3 and the mount succeeds.
