* statd: Decouple statd's state directory from the NFS state directorySteve Dickson2011-09-201-0/+9
| | | | | | | | | | | | | | To allow greater flexibility to where statd's state is kept, statd's state path can now be decoupled from the normal NFS state directory. In configure.ac, the NSM_DEFAULT_STATEDIR definition will now define the path to where the state information is kept. The default value, /var/lib/nfs, can be redefined with the --with-statdpath flag.

* mount: add --enable-libmount-mountKarel Zak2011-04-061-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to link mount.nfs with libmount from util-linux >= v2.19. The new libmount based code is enabled by CONFIG_LIBMOUNT and is stored in mount_libmount.c. The old code is not affected by this change. The libmount does not have officially stable API yet, so the --enable-libmount-mount is marked as experimental in the configure help output. The ./configure option is the same as we use in util-linux to enable support for libmount in mount(8). The addr= (and some other options necessary for remount/umount) are stored to /etc/mtab or to /dev/.mount/utab. The utab file is *private* libmount file. It's possible that some mount options (for example user=) will be moved to kernel, so the utab will not be necessary. About libmount: * supports systems without and with regular /etc/mtab * does not store VFS and FS mount options in userspace * manages user= option and evaluate permissions * parses VFS mount options and generate MS_* flags * parses /etc/{fstab,mtab}, /proc/mounts or /proc/self/mountinfo * long-term goal is to use the same code in all mount.<type> helpers Note, use LIBMOUNT_DEBUG=0xffff mount.nfs foo:/path /path to debug the library. On systems with util-linux v2.19 the findmnt(8) command uses libmount to list all/selected mount points: $ findmnt /path $ findmnt --mtab /path the --mtab appends userspace mount options (e.g. user=) to the output.

| | | | | | | | | | | | Due to the fact the current kernel code do not completely conform to the NFS 4.1 RFC, this patch disable the 4.1 support on the server.

* tcp_wrappers: Use getifaddrs(3) if it is availableChuck Lever2010-01-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After glibc 2.3.3, getifaddrs(3) can return AF_INET6 addresses for local network interfaces. Using the library call is easier than trying to update the open code in from_local(), and means we have less to maintain in nfs-utils going forward. And, since from_local() can now support IPv6, change its synopsis to take a "struct sockaddr *" . Note that the original code discovers local addresses once. These days, with wifi, DHCP, and NetworkManager, the local network configuration can change dynamically over time. So, call getifaddrs() more often to ensure from_local() has up-to-date network configuration information. This implementation refreshes the list if from_local() has not been called in the last second. This is actually not terribly honerous. check_default() invokes from_local() only when the remote host is not in its access cache, or the access/deny files have changed. So new hosts will cause a refresh, but previously seen hosts (including localhost) should not. On the other hand, it still may not be often enough. After the first call, if only previously seen hosts attempt to access our daemons, from_local() would never be called, and the local list would never be updated. This might be possible during steady-state operation with a small number of servers and clients. It would also be nice if we could free the local interface address list at shutdown time, but that would be a lot of trouble for little gain. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* libnsm.a: retain CAP_NET_BIND when dropping privilegesChuck Lever2010-01-151-0/+3
| | | | | | | | | | | | | | | | | I'm about to switch the order of listener creation and dropping root privileges. rpc.statd will drop privileges first, then create its listeners. The reason for the new ordering is explained in a subsequent patch. However, for non-TI-RPC builds, rpc_init() needs to use a privileged port to do pmap registrations. For both TI-RPC and non-TI-RPC builds, CAP_NET_BIND is required in case the admin requests a privileged listener port on the statd command line. So that these requirements are met, nsm_drop_privileges() will now retain CAP_NET_BIND while dropping root. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
* nfs-utils: introduce new statd testing simulatorJeff Layton2010-01-121-1/+3
| | | | | | | | | | | | | | | | | rpc.statd is often prone to subtle, difficult to detect breakage. When it has problems, they're often invisible and only manifest themselves as failed lock recovery. This program is intended to function as part of a test harness for statd. It's a multicall binary that serves as a synthetic NSM client program, and a daemon that can simulate lockd for purposes of testing the NSM to NLM downcall. A new top level "tests/" directory is also added to nfs-utils to start as a repository for automated tests of nfs-utils components.

* libnsm.a: Move the sm_inter XDR pieces to libnsm.aChuck Lever2009-12-231-0/+1
| | | | | | | | | | | | | | | | | | | | | Clean up: Move the .x file and the generated C source for NSM to libnsm.a, echoing the architecture of mountd and exportfs. This makes the NSM protocol definitions, data types, and XDR routines available to be shared across nfs-utils. This simplifies the addition of other NSM-related code (for example for testing or providing clustering support), and also provides public data type definitions that can be used to make sense of the contents of statd's on-disk database. Because sim_sm_inter.x still resides in utils/statd, I've left some rpcgen build magic in utils/statd/Makefile.am. This is an internal organization change only. This patch should not affect code behavior in any way. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>

We keep the code behind RESTRICTED_STATD, and toss anything that is compiled out when it is set. RESTRICTED_STATD was added almost 10 years ago in response to CERT CERT CA-99.05, which addresses exposures in rpc.statd that might allow an attacker to take advantage of buffer overflows in rpc.statd while it is running in privileged mode. These days, I can't think of a reason why anyone would want to run rpc.statd without setting RESTRICTED_STATD. In addition, I don't think rpc.statd is ever tested without it. Removing RESTRICTED_STATD will get rid of some address storage and comparison issues that will make IPv6 support simpler. Plus it will make our test matrix smaller!
