* exports: add a configurable time-to-live for the kernel cache entriesChuck Lever2011-04-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | From: Trond Myklebust <Trond.Myklebust@netapp.com> The fedfs ldap server will specify a ttl for its entries. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> This is a refactoring change only. There should be no change in behavior. Original patch had updates to utils/mountd/junctions.c, which no longer exists. These are not included here. Create a macro for the default cache TTL, which is used in several places besides the export cache. Make e_ttl unsigned.

* Read /etc/exports.d/*.export as extra export filesMasatake YAMATO2011-03-071-0/+6
| | | | | | | | | | | | | | | | This patch adding a capability to read /etc/exports.d/*.exports as extra export files to exportfs. If one wants to add or remove an export entry in a script, currently one may have to use sed or something tool for adding or removing the line for the entry in /etc/exports file. With the patch, adding and removing an entry from a script is much easier. cat<<EOF... or mv can be used for adding. rm can be used for removing.

* nfs-utils: Move common code into supportSteve Dickson2010-10-131-0/+6
| | | | | | | | | | There are several source files and headers present in the ./utils/idmapd directory which are also usable in a doimapd daemon. Because of this we move that support into the support directory such that it can be shared by both daemons. Signed-off-by: Jim Rees <rees@umich.edu> Signed-off-by: Steve Dickson <steved@redhat.com>
* libnfs.a: Fix API for getfh() & friendsChuck Lever2010-09-161-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is more of a clean-up than a behavioral change. POSIX requires that a "struct sockaddr" is the same size as a "struct sockaddr_in". Therefore, a variable or field of type "struct sockaddr" cannot contain an AF_INET6 address. However, "struct sockaddr *" is often used to reference a generic (ie non-address family specific) socket address, generating some confusion about this. The nfsctl_arg struct uses a struct sockaddr (not a pointer) to pass the client's IP address to the kernel. This means the legacy nfsctl() kernel API can never support IPv6. Fortunately for us, this legacy interface was replaced by a text-based cache interface a few years back. We don't need to support non-AF_INET addresses here. The getfh() functions in nfs-utils provide a handy C API for the kernel's nfsctl interface. The getfh() functions still take a struct sockaddr *, though, and that can imply that a non-IPv4 address can be passed via this API. To make it abundantly clear that only IPv4 addresses can be used with this interface, change the synopses of getfh() and friends to take a struct sockaddr_in * instead of a struct sockaddr * . This makes these functions conform with other places in mountd and exportfs that already grok the difference between a struct sockaddr and a struct sockaddr_in. While we're here... Introduce some nice documenting comments for the get_fh() functions, and... Since mountd will support IPv6 in the near future, assert that the family of client addresses passed to this API is indeed AF_INET, in order to prevent non-AF_INET addresses from ever being passed to the legacy nfsctl() interface.

* nfs-utils: move nfssvc.c to nfsd dir and clean up linking of nfsdJeff Layton2009-08-011-1/+0
| | | | | | | | | | rpc.nfsd is the only user of nfssvc.c, so we might as well move it out of libnfs.a. Also, don't link in libexport.a and libmisc.a, they aren't needed. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* utils/nfsd: add support for minorvers4Benny Halevy2009-05-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | minorvers4 can be used to either enable or disable nfsv4.x. If minorvers4 is a positive integer n, in the allowed range (only minorversion 1 is supported for now), the string "+4.n" is appended to the versions string written onto /proc/fs/nfsd/versions. Correspondingly, if minorver4 is a negative integer -n, the string "-4.n" is written. With the default value, minorvers4==0, the minor version setting is not changed. Note that unlike the protocol versions 2, 3, or 4. The minor version setting controls the *maximum* minor version nfsd supports. Particular minor version cannot be controlled on their own. With only minor version 1 supported at the moment the difference doesn't matter, but for future minor versions greater than 1, enabling minor version X will enable support for all minor versions 1 through X. Disabling minor version X will disable support for minor versions X and up, enabling 1 through X-1. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* Mountd should use separate lockfilesBen Myers2009-04-031-0/+9
| | | | | | | | | | | | | | | | Mountd keeps file descriptors used for locks separate from those used for io and seems to assume that the lock will only be released on close of the file descriptor that was used with fcntl. Actually the lock is released when any file descriptor for that file is closed. When setexportent() is called after xflock() he closes and reopens the io file descriptor and defeats the lock. This patch fixes that by using a separate file for locking, cleaning them up when finished. Signed-off-by: Ben Myers <bpm@sgi.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* Remove redundant m_path fieldJ. Bruce Fields2008-08-281-5/+0
| | | | | | | | | | | | | | | | | Contrary to the comment above its definition, the field m_path always has the same value as e_path: the *only* modifications of m_path are all of the form: strncpy(exp->m_export.m_path, exp->m_export.e_path, sizeof (exp->m_export.m_path) - 1); exp->m_export.m_path[sizeof (exp->m_export.m_path) - 1] = '\0'; So m_path is always just a copy of e_path. In places where we need to store a path to a submount of a CROSSMNT-exported filesystem, as in cache.c, we just use a local variable. Signed-off-by: J.

* rpc.mountd: make exportent->e_hostname a dynamically-allocated stringJeff Layton2007-09-281-1/+1
| | | | | | | | | | | | This makes the e_hostname field of the exportent into a pointer to a dynamically allocated string. This is necessary since this is field is often filled out from the m_hostname. This too adds a few micro-optimizations as we can avoid copying the string in some places and simply pass a pointer to the original string instead.

* Use UUIDs to identify filesystems if kernel supports it.Neil Brown2007-02-121-0/+1
| | | | | | | | | | | This introduces a new dependancy on libblkid. If a filesystem being exported has a UUID that libblkid can extract, then that is passed to the kernel for use in identifying the filesystem in filehandles. This means that 'fsid=' is no longer needed to work around the problem of device numbers changing. fsid= is still needed for fielsystems that have no device, and can now be given 16byute uuid instead of just a 32bit one.
* Error check messages sent to the kernel.Neil Brown2007-01-111-1/+1
| | | | | | And make sure that if we fail to export a filesystem in mountd, then we don't try to get a filehandle on it, or a deadlock might occur.
* Allow rpc.nfsd to suppress tcp or udp, and listen on a specific address.Steve Dickson2006-07-031-1/+1
| | | | | | | | | | -T - will suppressing listening for TCP connection. -U - will suppress UDP -H host - will only listen on that local address -p port - will listen on that port. This requires kernel patches which will hopefully be in 2.6.19 and possibly some earlier test and vendor kernels.
* Add support for suppressing different NFS versions.Steve Dickson2006-06-261-1/+1
| | | | | | e.g. -N 2 means that NFSv2 won't be supported, just v3 and v4 (if the kernel supports them).
