IZ65538: RH3 RPATH/RUNPATH VARIANCE CAUSES TIVOLI PROCESS FAILURES.

APAR status

• Closed as program error.

Error description

• Linux shared library calls are resolved via the links directory
  
  even when binary is neither owned by root nor when the binary is
  root SUID.  This unexpected variance in rpath/runpath causes
  Tivoli process failures when executing non-root binaries on a
  linux 2.4-based kernel (RH3 and SUSE8).
  

Local fix

• Detailed Recreation Procedure:
  
    Run a non-root, non-SUID Tivoli Monitoring process on RH3 or
  SUSE8
  
  Related Files and Output:
    RAS1 log of Tivoli Monitoring process shows hang or fault.
  

Problem summary

• Linux shared library calls are resolved via the links directory
  even when binary is neither owned by root nor when the binary is
  root SUID. This unexpected variance in rpath/runpath causes
  process failures when executing non-root binaries on a linux
  2.4-based kernel (RH3 and SUSE8).
  

Problem conclusion

• Code was modified to add DT_RUNPATH in addition to DT_RPATH, to
  facilitate proper pathing when executing non-root binaries.
  Tivoli Monitoring processes must re-build with this SDK for this
  fix to be effective.
  
  The fix for this APAR is included in the following maintenance
  vehicle:
      | fix pack | 6.2.1-TIV-ITM-FP0002
      | fix pack | 6.2.2-TIV-ITM-FP0002
  

Temporary fix

• Change binary ownership to root or root SUID.
