* nfs-utils: Restore ABI compat with pre-merge libnfsidmapJustin Mitchell2017-11-071-1/+1
| | | | | | | | | Prior to merge libnfsidmap leaked many private symbols that were not defined in its API, creating an accidental ABI. This patch renames and unhides symbols in order to match that ABI until a cleaned up API can be established and released. Signed-off-by: Steve Dickson <steved@redhat.com>

* nfsd: don't enable a UDP socket by defaultJeff Layton2017-04-052-11/+21
| | | | | | | | | | | | | | | | | | | Most major NFS clients have supported TCP for at least a decade now, and v4-only shops are becoming more prevalent. It seems reasonable that serving over UDP should be something that is "opt-in". I've always hesitated to do this in the past, but now that we have nfs.conf, it seems like the time may be right to disable UDP in default configurations. In particular, it would be good to try this in the more bleeding edge distros (Fedora, Ubuntu, SuSE, etc...) and see how problematic it is. Change the default in rpc.nfsd to just open TCP ports by default. Add new -u and -t options that allow users to explicitly override what's in the config file, and update the usage message and manpage.

* nfsd: Allow the caller to turn off NFSv4.0 without turning off NFSv4.xTrond Myklebust2017-04-054-33/+87
| | | | | | | | | | | | The new semantic is that '-N4' turns off all NFSv4 minor versions, while '-V4' turns them all on. In order to turn off just minor version x (x >= 0), use -N4.x, and to turn it back on. '-V4.x'. Note that on older kernels, attempting to use -N4.0 and -V4.0 is equivalent to specifying -N4 or -V4.

| | | | | | | | | | | | | | Several problem here: - code didn't actually work, as it cleared a bit from minorversset when it should have cleared from minorvers - code did not allow minor versions to be enabled, which is useful when a new minor version is partially implemented in the kernel but not yet enabled by default - code allowed version 4.0 to be enabled/disabled, which the kernel does not support (as for 4.9 at least).

* Remove all use of the nfsctl system call.NeilBrown2016-12-063-23/+7
| | | | | | | | | | | | | | | | | | | | 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.

Bruce Fields <bfields@fieldses.org> mentioned on the linux-nfs mailing list. I changed the data type back from an array to two bit fields, one for storing whether the minor version was specified on the command line and the second one for storing whether it was set or unset.

* autoconf: only link binaries that need it to libtirpcJeff Layton2012-01-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is essentially the same as the previous version, but has been respun to fix up some merge conflicts with some of Chuck's recent changes. When we first added tirpc support, we took a "big hammer" approach, and had it add libtirpc to $LIBS. That had the effect of making it so that that library was linked into every binary. That's unnecessary, and wasteful with memory. Don't let AC_CHECK_LIB add -ltirpc to $LIBS. Instead, have the autoconf tests set $(LIBTIRPC) in the makefiles, and have the programs that need it explicitly include that library. In the event that we're not using libtirpc, then set $LIBTIRPC to a blank string. This necessitates a change to the bindresvport_sa check too. Since that library is no longer included in $LIBS, we need to convert that check to use AC_CHECK_LIB instead of AC_CHECK_FUNCS. This patch also fixes a subtle bug. If the library was usable, but the includes were not, the test would set $enable_tirpc to "no", but HAVE_LIBTIRPC would still be true. That configuration would likely fail to build.

* rpc.nfsd: mount up nfsdfs is it doesn't appear to be mounted yetJeff Layton2010-09-163-3/+53
| | | | | | | | | | | | | | | | | | | | | | | | | There's a bit of a chicken and egg problem when nfsd is run the first time. On Fedora/RHEL at least, /proc/fs/nfsd is mounted up whenever nfsd is plugged in via a modprobe.conf "install" directive. If someone runs rpc.nfsd without plugging in nfsd.ko first, /proc/fs/nfsd won't be mounted and rpc.nfsd will end up using the legacy nfsctl interface. After that, nfsd will be plugged in and subsequent rpc.nfsd invocations will use that instead. This is a problem as some nfsd command-line options are ignored when the legacy interface is used. It'll also be a problem for people who want IPv6 enabled servers. The upshot is that we really don't want to use the legacy interface unless there is no other option. To avoid this situation, have rpc.nfsd check to see if the "threads" file is already present. If it's not, then make an attempt to mount /proc/fs/nfsd. This is a "best-effort" sort of thing, however so we just ignore the return code from the mount attempt and fall back to using nfsctl() if it fails.

* nfsd: fix version-setting regression on old kernelsJ. Bruce Fields2010-02-041-5/+5
| | | | | | | | | | | | | | | | | /proc/fs/nfsd/versions was extended to allow turning on/off minor versions by echoing "+4.1" or "-4.1" to /proc/fs/nsfd/versions. Unfortunately, pre-2.6.30 kernels just stop parsing at first non-digit, so "-4.1" is interpreted as "-4". If new nfs-utils (on old kernel) writes "+2", "+3", "+4", then "-4.1", result therefore is to turn off 4.1. Given that historical behavior, it may have been a mistake to extend the interface the way we did; but at this point we're probably stuck with it. So, just reverse the order we write versions in.
