Error description

• UNIX find and df fail getcwd() when using
  libatriagetcwd_interposer.so to address filesystem limitations
  on Solaris 10
  
  
  ClearCase 7.1.2.3 or 7.1.2.4
  
  
  Solaris 10
  
  
  To reproduce:
  
  
  1)  Export the following environment variables:
         export
  LD_PRELOAD_64=/usr/atria/shlib/sparcv9/libatriagetcwd_interposer
  .so
         export
  LD_PRELOAD_32=/usr/atria/shlib/libatriagetcwd_interposer.so
  
  
  2)  Try and issue a ?find ../?  or  ?df -h .? while:
     a)  Set to a view or ?setview -exec?
     b)  Within an NFS mount point
     c)  NFS mount has many symlinks to many other directories
  within the same export
     d)  lofs filesystem is in use (non-global zone)
  
  A truss of the command shows the following:
  
  24584:  0.2398  0.2098 getcwd(0x00029478, 1024)   Err#13 EACCES

  24584:  mt = Sep 26 14:24:02 CEST 2011  [ 1317039842 ]
  24584:  ct = Sep 26 14:24:02 CEST 2011  [ 1317039842 ]
  24584:     bsz=8192  blks=8     fs=nfs
  .
  .
  24584:  0.4979  0.2252 getcwd(0x0003B830, 1025)   Err#13 EACCES
  [file_dac_search]
  24584:  0.4983  0.0004 fstat64(2, 0xFFBFDD78)    = 0

  24584:  mt = Sep 26 14:24:15 CEST 2011  [ 1317039855 ]
  24584:  ct = Sep 26 13:37:47 CEST 2011  [ 1317037067 ]
  24584:     bsz=8192  blks=1     fs=lofs
  
  
  3)  Unsetting the environment variables above produces the
  'cannot determine the current working directory' error
  
  
  Workaround:  None

  ****************************************************************
  When using the shared library libatriagetcwd_interposer.so
  on Solaaris 10 as documented in Technote 1501830, some
  instances of the find and df commands would fail.
  

Problem conclusion

• A patch to the Solaris operating system is now available
  which eliminates the need for the libatriagetcwd_interposer
  library.? This patch is 147440-24 for SPARC systems, or
  147441-24 for x86 systems.
