Description Richard Morgan 2006-11-18 04:09:10 UTC

Description of problem:
FC6 i386 as client will not mount NFS shares from RH7.2, FC4.  It will mount 
shares from other FC6 servers no problems.  Also suspect Solaris 8 can not be 
mounted.

Error in syslog:
kernel: audit(1163816080.125:4): avc:  denied  { create } for  pid=1616 
comm="mount.nfs" scontext=system_u:system_r:mount_t:s0 tconte
xt=system_u:system_r:mount_t:s0 tclass=netlink_route_socket
N

Version-Release number of selected component (if applicable):
Linux version 2.6.18-1.2849.fc6 (brewbuilder.redhat.com) (gcc 
version 4.1.1 20061011 (Red Hat 4.1.1-30)) #1 SMP Fri Nov 10 12:45:28 EST 2006


How reproducible:
Build FC6 as NFS client, try to mount either FC4 or RH7.7 exports. 


Steps to Reproduce:
1.
2.
3.
  
Actual results:


Expected results:
should mount NFS shares from FC4 and RH7.2

Comment 2 Daniel Walsh 2006-11-20 20:12:26 UTC

Fixed in selinux-policy-2.4.3-10.fc6

Comment 3 Richard Morgan 2006-11-21 06:59:11 UTC

selinux is disbaled.  Applied selinux-policy-2.4.3-10.fc6, enabled selinux, 
reboot.  Still not working.  Disbaled selinux, reboot, again not working.

Buit whole new box with FC6, selinux emabled, applied selinux-policy-2.4.3-
10.fc6.  tried to mount original RH7.2 server, plus 1 other. still no 
success.  Solaris 8 does not work either.  I suspect this is a different bug.

Comment 4 Daniel Walsh 2006-11-21 19:54:09 UTC

If failing when SELinux is disabled, definitely not an SELinux problem. 
Although are you seeing any avc messages when SELinux is enabled?

Comment 5 Steve Dickson 2006-11-29 15:55:17 UTC

Could up post a bzip2 binary tethereal network trace of this
failure? Something like:
   
    tethereal -w /tmp/mount.pcap host <server> ; bzip2 /tmp/mount.pcap

Comment 6 Andrea Mastellone 2007-03-14 12:02:33 UTC

I have this problem, and SELinux is disabled. The NFS server is a FC3 distro
(until FC5 nfs clients are working greatly).

Comment 7 Steve Dickson 2007-03-14 14:43:01 UTC

what is the output of "mount -v /mnt/scsi"
also what does the /etc/fstab entry for /mnt/scsi
look like and finally could you post the output
of "strace mount /mnt/scsi"

Here are the requested data:

This: 
stat("/sbin/mount.nfs", 0x7fffbd817640) = -1 ENOENT (No such file or directory)

means your using an old nfs-utils... what version are you using?
