1/ only warn once per export, as it could get too noisy.
2/ make it a little clearer why this might be a problem.

They are identical and the later allows us to use hasmntent.

If "user" or "users" is given, then allow mount.nfs to be run
by a non-root user providing that the mountpoint, filesystem, and options
exactly match what is found in fstab.
For "user", record the user name in mtab so they can unmount the
filesystem later.
Also alwasys ignore auto, owner, group and their negations as well
as "_netdev", "comment" and "loop".

It appears that this is used only by unfsd, and is obscure enough that
we should be able to just rip it out with no special precautions.

When connecting to an NFSv4 server we need to find out IP address
as it would be seen by the server, to register an address for
callbacks.
This is most easily done by connecting the socket to the
servers address and then getting the address of our endpoint.
However with a connected UDP socket, replies that come from a
different IP address - as can happen with non-Linux multi-homed
servers - will be rejected.
So if we connected our UDP socket, we need to be sure to
disconnect it before using it.
This patch adds an option to get_socket to say if we want it
connected or not and, in the case where we do, we disconnect
a UDP socket after the connection information has been used.
Also clean up the error handling in clnt_ping which was getting
clumsy.

This was only needed for kernels 2.2.14 through 2.2.17.
These have long since been superceded, so remove some dead weight.

Extend exportfs interface to pass fslocations info into the kernel,
using syntax modelled after AIX. Adds "refer=" and "replicas="
options to /etc/exports to enable use of the kernel fslocation code.

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.

And make sure that if we fail to export a filesystem in mountd,
then we don't try to get a filehandle on it, or a deadlock
might occur.

-T - will suppressing listening for TCP connection.
-U - will suppress UDP
-H host - will only listen on that local address
-p port - will listen on that port.
This requires kernel patches which will hopefully be in 2.6.19 and possibly some
earlier test and vendor kernels.

e.g. -N 2
means that NFSv2 won't be supported, just v3 and v4 (if the kernel
supports them).

We need to give an IP address to identify this client to the
server.
The current code does a gethostbyname of the hostname. One
some systems this returns 127.0.0.1 or similar, which is not useful.
Instead, use getsockname of the sock used to connect to the server
to confirm that the server is working. This gives the address on the
interface that was chosen to talk to that server, which is the
best address we can find (if there is a NAT in the way, it might
still not work, but in that case there is nothing we can do).

Adds the support functions needed for mount and umount. This
functionality will someday be available in the form of shared mount

support/include/config.h.in from source control
These are auto autogenerated by
aclocal -I aclocal ; autoheader ; automake ; autoconf
|
| |
|
|
|
| |
Check for sufficient version of librpcsecgss and libgssapi
in configure.in
|
| |
|
|
|
| |
Update aclocal/tcp-wrappers.m4 to define HAVE_LIBWRAP and
HAVE_TCP_WRAPPERS as appropriate.
|
| | |
|
| |
|
|
| |
Fix support/include/config.h.in such as would be done be running autoheader.

Instead of having separate copies of the gssapi and rpcsecgss
header files, or depending on the Kerberos gssapi header,
locate the headers now installed with the libgssapi and librpcsecgss
libraries.
Remove local copies of the gssapi and rpcsecgss header files.
This depends on the configure_use_autotools patch.

* utils/exportfs/exports.man: Document the "crossmnt" export export option
* utils/gssd/krb5_util.c:
Add better debugging and partially revert the function
check for gss_krb5_ccache_name.
For MIT Kerberos releases up to and including 1.3.1, we *must*
use the routine gss_krb5_ccache_name to get the K5 gssapi code
to use a different credentials cache.
For releases 1.3.2 and on, we want to use the KRB5CCNAME
environment variable to tell it what to use.
(A problem was reported where 1.3.5 was being used, our
code was using gss_krb5_ccache_name, but the underlying
code continued to use the first (or default?) credentials
cache. Switching to using the env variable fixed the problem.
I cannot recreate this problem.
*utils/gssd/krb5_util.c:
Andrew Mahone <andrew.mahone@gmail.com> reported that reiser4
always has DT_UNKNOWN. He supplied patch to move the check
for regular files after the stat() call to correctly find
ccache files in reiser4 filesystem.
Also change the name comparison so that the wrong file is
not selected when the substring comparison is done.
*utils/gssd/krb5_util.c:
Limit the set of encryption types that can be negotiated by
the Kerberos library to those that the kernel code currently
supports.
This should eventually query the kernel for the list of
supported enctypes.
*utils/gssd/gss_util.c, utils/svcgssd/svcgssd_main_loop.c:
Print more information in error messages to help debugging failures.
*utils/svcgssd/svcgssd_proc.c: Increase token buffer size and
update error handling so that a response is always sent.
*utils/svcgssd/svcgssd_proc.c: Add support to retrieve
supplementary groups.

* configure.in etc
Consolidate some of the Kerberos checking instead of repeating
the same things for MIT and Heimdal.
Also adds more checks to distinguish 32-bit from 64-bit
(mainly for gssapi.h)
Fix svcgssd Makefile so make TOP=../../ works correctly there.
Enable running a modern autoheader.
* utils/gssd/gss_oids.c: Use correct OID value for SPKM-3
* utils/gssd/gss_util.c: Fix build with older MIT releases that do not define GSS_C_NT_HOSTBASED_SERVICE
* utils/gssd/write_bytes.h, support/include/gssapi/gssapi.h:
Length of gss_buffer_desc is a size_t which is 64-bits on a
64-bit machine. Kernel code expects 32-bit integer for length.
Coerce length value into a 32-bit value when reading from or
writing to the kernel.
Change gssapi.h to use datatype size values obtained from
configure rather than hard-coded values.
* utils/idmapd/idmapd.c: The EV_INIT check here was wrong, and was
causing idmapd to become unresponsive to server requests after
receiving a sighup.
* utils/idmapd/idmapd.c: Idmapd should flush the server id<->name
caches when its started.
