DB2 FOR LUW / DB2FORLUW / B10 - DB2

Silent installation of DB2 (db2setup) or instance setup 
(db2isetup) using response file might fail with no error 
returned to the installation log file due to a segmentation 
fault (SEGV). The SEGV might be logged to the operating system 
log file (errpt, messages) indicating a failure of db2iure 
executable, e.g.: 
 
db2iure[28993]: segfault at 0 ip 00007f51f7f7b748 
sp00007ffc1b897108 error 4 in 
libdb2ure.so.1[7f51f7c1e000+4b0000] 
 
A core file will show that error is triggered with following 
functions on the top of the stack: 
 
__intel_sse2_strcpy 
UserManager::encodePassword 
UserManager::setPassword 
IUser::setPassword 
UREInstance::initializeSettings 
TaskBuildInstanceList::execute 
URE::start() 
 
Problem will be observed in the environments where libc crypt() 
function, used to encode the password in response file, returns 
an error, which might happen in the environments where FIPS mode 
is enforced on the system. On Linux, where problem  originally 
reported, this can be checked by verifying value of 
/proc/sys/crypto/fips_enabled: 
  EPERM  /proc/sys/crypto/fips_enabled has a nonzero value, and 
an 
         attempt was made to use a weak encryption type, such as 
DES.
