* Remove all use of the nfsctl system call.NeilBrown2016-12-061-16/+0
| | | | | | | | | | | | | | | | | | | | This systemcall was deprecated early in the 2.6 series as it was replaced by an in-kernel cache which was refilled using an upcall. All communication to kernel is now through the nfsd filesystem. The nfsctl systemcall itself was removed in 3.1. It is unlikely to have been used for over a decade. To remove all uses for the nfsctl systemcall, and call code that only runs when "new_cache" is false. We now assume "new_cache" is always true. This allows the removal of several files as well as assorted functions. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* Remove all use of /var/lib/nfs/xtabNeilBrown2016-11-151-9/+0
| | | | | | | | | | | | | | | /var/lib/nfs/xtab is only used to find out what has been exported to the kernel. This is more reliably done by reading /proc/fs/nfs{,d}/export and nfs-utils uses that file if is available. So xtab is only need if you have an incredibly ancient kernel which doesn't have /proc/fs/nfs/export (and so which only supports NFSv2) or if /proc is not mounted. Neither of these are credible contexts to run a modern nfs-utils, so stop creating or reading the xtab file. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Steve Dickson <steved@redhat.com>

* cleanup daemonization codeDavid Hardeman2015-01-231-2/+3
| | | | | | | | | | | | | | | The daemonization init/ready functions have parameters that are never used, require the caller to keep track of some pipefds that it has no interest in and which might not be used in some scenarios. Cleanup both functions a bit. The idea here is also that these two functions might be good points to insert more systemd init code later (sd_notify()). Also, statd had a private copy of the daemonization code for unknown reasons...so make it use the generic version instead.

* rpc.mountd: set nonblocking mode if no libtirpcBodo Stroesser2014-11-121-0/+1
| | | | | | | | | | | | | If mountd is built without libtirpc and it is started using "-p XXX" option, the tcp listeners and the sockets waiting for UDP messages are not in non-blocking mode. Thus if running with multiple threads (-t XX), all threads will wake up from select on a connection request or a UDP message, but only one thread will succeed. All others will wait on accept() or read() for the next event.

* nfs-utils: consolidate mydaemon() and release_parent() implementationsJeff Layton2013-11-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | We currently have 2 cut-and-paste versions of this code. One for idmapd and one for svcgssd.[1] The two are basically equivalent but there are some small differences, mostly related to how errors in that function are logged. svcgssd uses printerr() with a priority of 1, which only prints errors if -v was specified. That doesn't seem to be quite right. Daemonizing errors are necessarily fatal and should be logged as such. The one for idmapd uses err(), which always prints to stderr even though we have the xlog facility set up. Since both have xlog configured at this point, log the errors using xlog_err() instead. The only other significant difference I see is that the idmapd version will open "/" if it's unable to open "/dev/null". I believe that however was a holdover from an earlier version of that function that did not error out when we were unable to open a file descriptor. Since the function does that now, I don't believe we need that fallback anymore. [1]: technically, we have a third in statd too, but it's different enough that I don't want to touch it here.

* 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.

* 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.

* 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
