Description JianHong Yin 2013-11-15 03:00:09 UTC 
Description of problem:
When export dir with sec=krb5; Client mount success, but ls fail with permission, and ls -l return invalid argument.

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


How reproducible:
100%

Steps to Reproduce:
1. In server, krb5 config and add keytab file
   start rpcsvcgssd
   export "/usr/share *(ro,sec=krb5)"
   start nfs server
2. In client, krb5 config and add keytab file
   start rpcgssd
   mount $server:/usr/share  /nfsmp
   ls -l /nfsmp
   ls /nfsmp
3.

Actual results:
================================================================================
[21:09:35 root@ /mnt/tests/CoreOS/nfs-utils/krb5-test/base]# showmount -e $SERVER_nfs
Export list for hp-sl390s-01.rhts.eng.bos.redhat.com:

================================================================================
[21:09:36 root@ /mnt/tests/CoreOS/nfs-utils/krb5-test/base]# mount $SERVER_nfs:/usr/share  /nfs-mp

================================================================================
[21:09:36 root@ /mnt/tests/CoreOS/nfs-utils/krb5-test/base]# mount | grep "$SERVER_nfs:/usr/share"
hp-sl390s-01.rhts.eng.bos.redhat.com:/usr/share on /nfs-mp type nfs (rw,addr=10.16.67.67)
--------------------------------------------------------------------------------

================================================================================
[21:09:36 root@ /mnt/tests/CoreOS/nfs-utils/krb5-test/base]# ls -d /nfs-mp
/nfs-mp
--------------------------------------------------------------------------------

================================================================================
[21:09:36 root@ /mnt/tests/CoreOS/nfs-utils/krb5-test/base]# ls -l /nfs-mp | tail
ls: /nfs-mp: Invalid argument  <<<--- when use ls -l, get Invalid argument err.
ls: /nfs-mp: Permission denied
--------------------------------------------------------------------------------

================================================================================
[21:09:36 root@ /mnt/tests/CoreOS/nfs-utils/krb5-test/base]# ls    /nfs-mp | tail
ls: /nfs-mp: Permission denied

The EINVAL is coming from how the 
   getxattr("/mnt/home", "system.posix_acl_access", 0x0, 0)
system fails.

When the mount is mounted using the -o sec=krb5 flag the
system call fails with ENODATA which is not printed to sdterr
but when -o sec=krb5 flag is not used the system call fails 
with a EINVAL which is written to stderr by the ls command.

This is simply a function of how ls works in RHEL5
