Error description

• Tivoli Storage Manager Backup & Archive Client supports backup
  and restore of Linux extended attribute like Linux
  security.capability.  However, the client may fail to restore
  the  security.capability set on a non-empty file.
  
  .
  L2/Customer diagnostics:
  
  1: security.capability. was set on a non-empty file:
  
  # getcap tcpserver
  tcpserver = cap_net_bind_service+ep
  [root@ganesh source]# attr -l tcpserver
  Attribute "selinux" has a 28 byte value for tcpserver
  Attribute "capability" has a 20 byte value for tcpserver
  2: perform a backup of the file:
  dsmc i tcpserver
  ...
  Normal File-->             9,907 /var/scratch/source/tcpserver
  [Sent]
  Successful incremental backup of '/var/scratch/source/tcpserver'
   ...
  
  3: perform a restore of the file:
   dsmc restore 'tcpserver*' /var/scratch/restore/
  ..
  Restoring           9,907 /var/scratch/source/tcpserver -->
  /var/scratch/restore/source/tcpserver [Done]
  ..
  4: verify the attribute after restore:
  [root@ganesh source]# attr -l
  /var/scratch/restore/source/tcpserver.c
  Attribute "selinux" has a 28 byte value for
  /var/scratch/restore/source/tcpserver.c
  
  Note: the "Attribute "capability" is missing after the
  restore
