add NFSv4 support

[Timo Aaltonen]

mount lacks NFSv4 support, patches for it are here:

http://www.citi.umich.edu/projects/nfsv4/linux/util-linux-patches/2.12-3/

NFSv4 is becoming actually useful, so having it in dapper would be very
important. Rest of the tools that are needed support it already.

duh, so there is was already this bug from debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=302420

but didn't notice that the maintainer is the same ;) Still, how about applying
this now, still plenty of time before dapper?

does this mean that NFSv4-support is not coming before upstream? That would be
very bad because debian/ubuntu is/are the only major distros not supporting
NFSv4 on userland. I'll attach patches that were synced for util-linux_2.12r-2.

What the status of this bug? I still get "wrong fs type" when I try to mount an nfs4 export...

[Timo Aaltonen (tjaalton)]

there was a problem with those patches, they broke nfs-user-server, but now there is version -8.2 in debian experimental which has a fix for the breakage. Hopefully that is good enough so this can get in for dapper.

Oh, and the error I get from mount isn't very helpful:

       In some cases useful info is found in syslog - try
       dmesg | tail or so
-----------------

No syslog messages are generated in fact.

[AleksanderAdamowski (aadamowski)]

OK, I had an old version of mount because of the package loop-aes-utils that I've installed some time ago to mount an old filesystem encrypted with loop-AES and migrate it to LUKS.

Now I've removed that package and restored the original mount.

It shows the following version:

# mount -V
mount: mount-2.12r

However, it still fails. Additionally, it tells me that gssd is not running (although it is, but mount looks for the pidfile in the wrong file):

-------------
# mount -t nfs4 -o sec=krb5,proto=tcp,port=2049 servername:/home/nfs/ /nfs/
Warning: rpc.gssd appears not to be running.

Mount looks for /var/run/rpc.gssd, while the real pidfile is /var/run/rpc.gssd.pid on Dapper.

Regarding the search for mount.nfs4 - mount does this, but it appears earlier in the strace, so it's not visible above.

Here's the relevant strace fragment:

....
lstat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=484, ...}) = 0
stat64("/sbin/mount.nfs4", 0xbf81582c) = -1 ENOENT (No such file or directory)
gettimeofday({1173993365, 294378}, NULL) = 0
getpid() = 6800
open("/etc/resolv.conf", O_RDONLY) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=149, ...}) = 0
....

The most suspicious behaviour of mount is the double attempt at closing the TCP socket it has opened to the NFS server. Notice this fragment in the strace:

---
connect(3, {sa_family=AF_INET, sin_port=htons(2049), sin_addr=inet_addr("192.168.1.1")}, 16) = 0
gettimeofday({1173993083, 563383}, NULL) = 0
write(3, "\200\0\0(V\303\313\334\0\0\0\0\0\0\0\2\0\1\206\243\0\0"..., 44) = 44
poll([{fd=3, events=POLLIN, revents=POLLIN}], 1, 20000) = 1
read(3, "\200\0\0\30V\303\313\334\0\0\0\1\0\0\0\0\0\0\0\0\0\0\0"..., 400) = 28
close(3) = 0
close(3) = -1 EBADF (Bad file descriptor)
---

This is clearly wrong.

OK, sorry for the spam, I forgot to modprobe rpcsec_gss_krb5 kernel module on the client.

All the described problems were harmless.
The incorrect warning about rpc.gssd not running was fixed in Edgy, but it doesn't cause any problems.
