**Status:** accepted
**Milestone:** 5.1.RC1
**Created:** Tue Sep 06, 2016 08:15 AM UTC by Srikanth R

**Owner:** Mathi Naickan
Environment details
------------------
OS : Suse 64bit
Changeset : 7997 ( 5.1.FC)
Setup : 5 nodes ( 2 controllers and 3 payloads with headless feature disabled &
no PBE )
AMF Application : 2N model with SUs mapped on PL-3,PL-4
Steps followed & Observed behaviour
------------------
-> Call saClmClusterTrack_4 api with CURRENT flag and buffer parameter
populated. Here the buffer paramter is populated by allocating suffiicent
memory of numberOfItems but notification is having garbage values.
Agent crashed with the following back trace, if notification is having garbage
values.
-> #3 0x00007f4ccb370c9f in osaf_extended_name_length (name=0x9d5e4e) at
osaf_extended_name.c:139
-> #4 0x00007f4cca9ff27c in clma_validate_flags_buf_4 (hdl_rec=0x97cbc0,
flags=1 '\001', buf=0x97c190) at clma_api.c:183
->#5 0x00007f4ccaa00fe5 in clmaclustertrack (clmHandle=4290772993, flags=1
'\001', buf=0x0, buf_4=0x97c190) at clma_api.c:1032
->#6 0x00007f4ccaa00d40 in saClmClusterTrack_4 (clmHandle=4290772993, flags=1
'\001', buf=0x97c190) at clma_api.c:958
Expected behaviour
------------------
If the buffer parameter is NULL, CLM shall invoke a callback. If the buffer
parameter is not NULL, CLM should check only value of numberOfItems and
evaluate whether sufficient memory is allocated by user or not.
With the #1906 changes, contents of notification are also verified. But only
structure member numberOfItems is to be verified.
