* libnsm.a: Add support for multiple lines in monitor record filesChuck Lever2010-01-151-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support IPv6, statd must support multi-homed remote peers. For our purposes, "multi-homed peer" means that more than one unique IP address maps to the one canonical host name for that peer. An SM_MON request from the local lockd has a "mon_name" argument that statd reverse maps to a canonical hostname (ie the A record for that host). statd assumes the canonical hostname is unique enough that it stores the callback data for this mon_name in a file named after that canonical hostname. Because lockd can't distinguish between two unique IP addresses that may be from the same physical host, the kernel can hand statd a mon_name that maps to the same canonical hostname as some previous mon_name. So that the kernel can keep this instance of the mon_name unique, it creates a fresh priv cookie for each new address. Note that a mon_name can be a presentation address string, or the caller_name string sent in each NLMPROC_LOCK request. There's nothing that requires the caller_name to be a fully-qualified hostname, thus it's uniqueness is not guaranteed. The current design of statd assumes that canonical hostnames will be unique enough. When a mon_name for a fresh SM_MON request maps to the same canonical hostname as an existing monitored peer, but the priv cookie is new, statd will try to write the information for the fresh request into an existing monitor record file, wiping out the contents of the file. This is because the mon_name/cookie combination won't match any record statd already has. Currently, statd doesn't check if a record file already exists before writing into it. statd's logic assumes that the svc routine has already checked that no matching record exists in the in-core monitor list. And, it doesn't use O_EXCL when opening the record file. Not only is the old data in that file wiped out, but statd's in-core monitor list will no longer match what's in the on-disk monitor list. Note that IPv6 isn't needed to exercise multi-homed peer support. Any IPv4 peer that has multiple addresses that map to its canonical hostname will trigger this behavior. However, this scenario will become quite common when all hosts on a network automatically get both an IPv4 address and an IPv6 address. I can think of a few ways to address this: 1. Replace the current on-disk format with a database that has a uniqueness constraint on the monitor records 2. Create a new file naming scheme; eg. one that uses a truly unique name such as a hash generated from the mon_name, my_name, and priv cookie 3. Support multiple lines in each monitor record file Since statd's on-disk format constitutes a formal API, options 1 and 2 are right out. This patch implements option 3. There are two parts: adding a new line to an existing file; and deleting a line from a file with more than one line. Interestingly, the existing code already supports reading more than one line from these files, so we don't need to add extra code here to do that. One file may contain a line for every unique mon_name / priv cookie where the mon_name reverse maps to the same canonical hostname. We use the atomic write facility added by a previous patch to ensure the on-disk monitor record list is updated atomically. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* nfs-utils: Collect socket address helpers into one locationChuck Lever2010-01-152-11/+238
| | | | | | | | | | | | | Introduce generic helpers for managing socket addresses. These are general enough that they are useful for pretty much any component of nfs-utils. We also include the definition of nfs_sockaddr here, so it can be shared. See: https://bugzilla.redhat.com/show_bug.cgi?id=448743 Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* libnsm.a: Add RPC construction helper functionsChuck Lever2010-01-151-0/+25
| | | | | | | | | | | | | | | | | | | To manage concurrency, both statd and sm-notify construct raw RPC requests in socket buffers, and use a minimal request scheduler to send these requests and manage replies. Both statd and sm-notify open code the RPC request construction. Introduce helper functions that can construct and send raw NSMPROC_NOTIFY, NLM downcalls, and portmapper calls over a datagram socket, and receive and parse their replies. Support for IPv6 and RPCB_GETADDR is featured. This code (and the IPv6 support it introduces) can now be shared by statd and sm-notify, eliminating code and bug duplication. This implementation is based on what's in utils/statd/rmtcall.c now, but is wrapped up in a nice API and includes extra error checking. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

* libnsm.a: Introduce common routines to handle persistent storageChuck Lever2010-01-122-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | rpc.statd and sm-notify access the same set of files under /var/lib/nfs/statd, but both have their own code base to handle this. They should share this code. In addition, the on-disk format used by statd and friends is considered a formal interface, so this new code will codify the API and provide documentation for it. The shared code handles switching from the default parent statd directory, reducing privileges at start-up, and managing the NSM state files, in addition to handling normal operations on the monitored host and notification lists on disk. The new code is simply a copy of the same logic that was used in rpc.statd and sm-notify, but wrapped in a nice API. There should be minimal behavioral and no on-disk format changes with the new libnsm.a code. The new code is more careful to check for bad corner cases. Occassionally this code may not allow an operation that was permitted in the past, but hopefully the error reporting has improved enough that it should be easy to track down any problems.

* utils/nfsd: add support for minorvers4Benny Halevy2009-05-042-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* support: Provide an API for creating a privileged RPC clientChuck Lever2009-04-181-1/+10
| | | | | | | | | | | | | | We needed to guarantee that some RPC programs, such as PMAP, got an unprivileged port, to prevent exhausting the local privileged port space sending RPC requests that don't need such privileges. nfs_get_rpcclient() provides that feature. However, some RPC programs, such as MNT and UMNT, require a privileged port. So, let's provide an additional API for this that also supports IPv6 and setting a destination port.

* 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>

* Exportfs and rpc.mountd optimalizationTomas Richter2009-02-181-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | There were some problems with exportfs and rpc.mountd for long export lists - see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=76643 I do optimalization as my bachelors thesis (Facuulty of informatics, Masaryk's university Brno, Czech Republic), under lead of Yenya Kasprzak. Both exportfs and rpc.mount build linked list of exports (shared functions in export.c). Every time they are inserting new export into list, they search for same export in list. I replaced linked list by hash table and functions export_add and export_lookup by functions hash_export_add and hash_export_lookup (export.c). Because some other functions required exportlist as linked list, hash table has some implementation modification im comparison with ordinary hash table. It also keeps exports in linked list and has pointer to head of the list. So there's no need of implementation function <for_all_in_hash_table>.

* Introduce rpcbind client utility functionsChuck Lever2008-11-171-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that at least the mount command and the showmount command need to query a server's rpcbind daemon. They need to query over AF_INET6 as well as AF_INET. libtirpc provides an rpcbind query capability with the rpcb_getaddr(3) interface, but it takes a hostname and netconfig entry rather than a sockaddr and a protocol type, and always uses a lengthy timeout. The former is important to the mount command because it sometimes must operate using a specific port and IP address rather than depending on rpcbind and DNS to convert a [hostname, RPC program, netconfig] tuple to a [socket address, port number, transport protocol] tuple. The rpcb_getaddr(3) API also always uses a privileged port (at least for setuid root executables like mount.nfs), which is not required for an rpcbind query. This can exhaust the local system's reserved port space quickly. This patch provides a reserved-port-friendly AF_INET6-capable rpcbind query C API that can be shared among commands and tools in nfs-utils, and allows a query to a specified socket address and port rather than a hostname. In addition to an rpcbind query interface, this patch also provides a facility to ping the remote RPC service to ensure that it is operating as advertised by rpcbind. It's useful to combine an RPC ping with an rpcbind query because in many cases, components of nfs-utils already ping an RPC service immediately after receiving a successful GETPORT result. There are also a handful of utility routines provided, such as a functions that can map between [sockaddr, port] and a universal address. I've made an attempt to make these new functions build and operate on systems that do not have libtirpc.
