I think I've found it:

ftp://ftp.software.ibm.com/software/tivoli_support/patches/patches_6.0.0/6.0.0-TIV-PDO-FP0007/6.0.0-TIV-PDO-Linux.i386-FP0007.tar

Is that correct?

  kail_trap_syscalls() 

seems to be revectoring the syscall table and siliently disabling any 
active LSM.


  kail_restore_syscalls()

attempts to restore them on module unload.


Is my understanding correct?

You're shipping this to customers as a security feature?
