Description IBM Bug Proxy 2013-10-18 06:22:48 UTC
== Comment: #0 - Sumanth K <sumantk2.com> - 2013-10-17 02:34:20 ==
slapd daemon hits segmentation fault during start while running openldap test.

patch openldap-security-pie.patch was causing segmentation fault in s390x architecture. S390x arch requires -fPIE option instead of -pie . 

From man page of gcc it is specified as follow:
-pie options assumes GOT entries and small data are within a 12-bit range from the 
GOT base address; with -fPIC or -fPIE, GOT offsets are computed with 32 bits.
The -pie option was causing segmentation fault in s390x.

Attached patch fixes the issue.

Hi kamalesh,

while having a look ...

-f option in the link phase seems to be different and hence i think it doesnt make it Position independent.

i have misunderstood the option of  gcc with ld...However the following patch openldap-security-pie.patch is causing problem...Will try to fix it..

One way to overcome this might be  to export CFLAGS="-fPIC" in the openldap.spec if it is s390x....

Pushed (to master only):
http://pkgs.fedoraproject.org/cgit/openldap.git/commit/?id=4f8940365cb6519fc8b5a785cc617ce808e11d89

You can find a srpm at http://koji.fedoraproject.org/koji/buildinfo?buildID=472772.

I tested this on an s390x machine and all seems fine. I'll leave this in master for a while, unless I have a positive response from the reporter.
