Support group-id looks for kernels that ask for them.
With "-g" mountd will listen for uid -> gidlist requests
from the kernel and provide the required mapping.
This is specific to AUTH_USER (aka AUTH_SYS) and is designed
to overcome the 16-gid limit in the AUTH_UNIX protocol.

Use UUIDs to identify filesystems if kernel supports it.
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.

This mostly takes care of the difference between - and \-; in

that a line might be split at that point), while the latter is a
dash. For options, the latter is correct.

Stop using storage after free
Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Kevin Coffman <kwc@citi.umich.edu>
The previous patch seems to expose a use after free bug in dirscancb. At
least, I could reliably reproduce a segfault by doing a bunch of mounts
and then unmounting them all. The code uses the following list macro:
TAILQ_FOREACH(ic, icq, ic_next) {
...to iterate over all of the ic entries and clean up any that no longer
have a corresponding directory in rpc_pipefs. This macro unrolls into:
for(ic=icq->tqh_first; ic != NULL; ic=ic->ic_next.tqe_next) {
...but within this loop, we can free ic, and then the for loop can trip
over that when it tries to do the iteration. The attached patch works
around this by not using the TAILQ_FOREACH macro and saving off the
tqe_next pointer prior to the free.
Again, this was tested on a patched 1.0.6, but the 1.0.10 code is very
similar, and I think the problem exists there as well. Signed-off-by: Neil Brown <neilb@suse.de>

Fix memory leak in idmapd.
Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Kevin Coffman <kwc@citi.umich.edu>
There is a pretty nasty memory leak in idmapd in dirscancb(). Some of
our customers have reported that idmapd can eat gigabytes of memory on
machines with a large number of mounts and unmounts and a long uptime.
That function uses scandir(), which malloc's an array of strings, but
dirscancb() never frees the strings or the array. The following patch
should correct this, but I've not yet tested it on 1.0.10 (only on the
RHEL4 1.0.6 version). Still, the code is very similar and I'm fairly
certain the problem exists in both versions. Signed-off-by: Neil Brown <neilb@suse.de>

Add AM_MAINTAINER_MODE to configure.in

As requested by "Steinar H. Gunderson" <sgunderson@bigfoot.com>, add
AM_MAINTAINER_MODE to configure.in. See the description of this
macro below:
`AM_MAINTAINER_MODE' disables the so called "rebuild rules" bys
default. If you have `AM_MAINTAINER_MODE' in `configure.ac', and
run `./configure && make', then `make' will *never* attempt to
rebuild `configure', `Makefile.in's, Lex or Yacc outputs, etc.
I.e., this disables build rules for files which are usually
distributed and that users should normally not have to update.
If you run `./configure --enable-maintainer-mode', then these
rebuild rules will be active. Signed-off-by: Neil Brown <neilb@suse.de>

- set ACLOCAL_AMFLAGS so that when running autoreconf or when
autotools re-runs itself, the m4 files are found properly
- make sure we include bsdsignals.m4 in the final tarball
- add some cross-compiling fallback logic to bsdsignals.m4 so that
