| | | | | | | | | | | | | | | | interfaces are configured, but for many interfaces (e.g. all Intel) ifconfig causes link renegotiation, so the first attempt to mount NFS always fails. After that mount_nfs sleeps for 30 seconds, while only a couple seconds are actually required for interface to get up. Instead of sleeping, do select(2) on routing socket and check if some interface became UP and in this case retry immediately.

* Fix mount_nfs to recognize the NFSv4 specific errors returned by nmount(2).Rick Macklem2019-12-261-5/+11
| | | | | | | | | | | | | | | | | | | When mount_nfs calls nmount(2), certain NFSv4 specific errors such as NFSERR_MINORVERMISMATCH can be returned. Without this patch, 10021 is reported as an unknown error. This is not particulcarily serious, but make it difficult for sysadmins to figure out why the mount attempt is failing. This patch uses nfsv4_errstr.h to convert 10021 and similar to error strings that can be printed out. A positive side effect of this patch is the removal of a reference to sys/nfsclient/nfs.h, which should no longer be used, since it is part of the old NFS client. This patch should only affect reporting of failed mount attempts and not the semantics of NFS mount attempts. Notes: svn path=/head/; revision=356101
* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* Fix mount_nfs so that it doesn't create mounttab entries for NFSv4 mounts.Rick Macklem2017-05-081-1/+1

| | | | | | | | | | | | | | | | | NFS client (which I guess is no longer experimental). The fstype "newnfs" is now "nfs" and the regular/old NFS client is now fstype "oldnfs". Although mounts via fstype "nfs" will usually work without userland changes, an updated mount_nfs(8) binary is needed for kernels built with "options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and mount(8) binaries are needed to do mounts for fstype "oldnfs". The GENERIC kernel configs have been changed to use options NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER. For kernels being used on diskless NFS root systems, "options NFSCL" must be in the kernel config. Discussed on freebsd-fs@. Notes: svn path=/head/; revision=221124

* Implement support for RPCSEC_GSS authentication to both the NFS clientDoug Rabson2008-11-031-1/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and server. This replaces the RPC implementation of the NFS client and server with the newer RPC implementation originally developed (actually ported from the userland sunrpc code) to support the NFS Lock Manager. I have tested this code extensively and I believe it is stable and that performance is at least equal to the legacy RPC implementation. The NFS code currently contains support for both the new RPC implementation and the older legacy implementation inherited from the original NFS codebase. The default is to use the new implementation - add the NFS_LEGACYRPC option to fall back to the old code. When I merge this support back to RELENG_7, I will probably change this so that users have to 'opt in' to get the new code. To use RPCSEC_GSS on either client or server, you must build a kernel which includes the KGSSAPI option and the crypto device. On the userland side, you must build at least a new libc, mountd, mount_nfs and gssd. You must install new versions of /etc/rc.d/gssd and /etc/rc.d/nfsd and add 'gssd_enable=YES' to /etc/rc.conf. As long as gssd is running, you should be able to mount an NFS filesystem from a server that requires RPCSEC_GSS authentication. The mount itself can happen without any kerberos credentials but all access to the filesystem will be denied unless the accessing user has a valid ticket file in the standard place (/tmp/krb5cc_<uid>). There is currently no support for situations where the ticket file is in a different place, such as when the user logged in via SSH and has delegated credentials from that login. This restriction is also present in Solaris and Linux. In theory, we could improve this in future, possibly using Brooks Davis' implementation of variant symlinks. Supporting RPCSEC_GSS on a server is nearly as simple. You must create service creds for the server in the form 'nfs/<fqdn>@<REALM>' and install them in /etc/krb5.keytab. The standard heimdal utility ktutil makes this fairly easy. After the service creds have been created, you can add a '-sec=krb5' option to /etc/exports and restart both mountd and nfsd. The only other difference an administrator should notice is that nfsd doesn't fork to create service threads any more. In normal operation, there will be two nfsd processes, one in userland waiting for TCP connections and one in the kernel handling requests. The latter process will create as many kthreads as required - these should be visible via 'top -H'. The code has some support for varying the number of service threads according to load but initially at least, nfsd uses a fixed number of threads according to the value supplied to its '-n' option.
