Description Jerome 2002-11-22 18:36:14 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003

Description of problem:
Mount options (exec...) not honored for AIX NFS mounted filesystems.
RedHat 8.0 is the client; AIX 5.1 is the server.
/etc/fstab:
dosxx:/linux  /images  nfs  sync,exec,suid,dev,tcp,rsize=8192,wsize=8192,...
After mount performed, cat /proc/mounts reports:
dosxx:/linux /images nfs rw,sync,nosuid,nodev,noexec,...

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Specify exec mount option for an NFS filesystem
2.Mount the filesystem
3.Check /proc/mounts or try to execute a Linux executable or shell from the
mounted filesystem
	

Actual Results:  Cannot execute any files from the NFS mounted filesystem
(/bin/sh: bad interpreter: Permission denied)

Expected Results:  Being able to execute Linux executables and shells from the
mounted filesystems.

Comment 1 Elliot Lee 2002-12-10 15:40:44 EST
From the error message, it seems as if the actual problem is elsewhere (_bad 
interpreter_). Please investigate with ls -l before concluding that the mount options are the 
problem.

There is really no way that util-linux or even the kernel is changing its behaviour based on 
the fact that the server is an AIX one.
