Fixed In Version: 389-ds-base-1.3.4.0-23.el7_2
Doc Type: Bug Fix
Doc Text:
Prior to this update, when the cleanAllRUV task was running, a bogus attrlist_replace error message was logged repeatedly due to a memory corruption. With this update, the appropriate memory copy function memmove is used, which fixes the memory corruption. As a result, the error messages are no longer logged in this scenario.

[root@blade04 ~]# rpm -qa | grep -i 389-ds-base
389-ds-base-libs-1.3.4.0-23.el7_2.x86_64
389-ds-base-devel-1.3.4.0-23.el7_2.x86_64

Verification steps:
1) Install RHDS instance and set up some replicas. I have six master replication setup.
[root@blade04 ~]# ldapsearch -h localhost -p 1289 -D "cn=Directory Manager" -w Secret123 -b "cn=replica,cn=dc\3Dpasssync\2Cdc\3Dcom,cn=mapping tree,cn=config" -s base objectclass=* nsds50ruv

dn: cn=replica,cn=dc\3Dpasssync\2Cdc\3Dcom,cn=mapping tree,cn=config
nsds50ruv: {replicageneration} 56961ad0000008a30000
nsds50ruv: {replica 2212 ldap://blade04.idm.lab.eng.rdu2.redhat.com:1289}
nsds50ruv: {replica 2211 ldap://blade04.idm.lab.eng.rdu2.redhat.com:1189} 5696
 1ca3000008a30000 56961ca4000908a30000
nsds50ruv: {replica 2216 ldap://blade04.idm.lab.eng.rdu2.redhat.com:3289}
nsds50ruv: {replica 2215 ldap://blade04.idm.lab.eng.rdu2.redhat.com:3189}
nsds50ruv: {replica 2214 ldap://blade04.idm.lab.eng.rdu2.redhat.com:2289}
nsds50ruv: {replica 2213 ldap://blade04.idm.lab.eng.rdu2.redhat.com:2189}


2) Clean rid 2216, where rid 2211 is the local rid.
[root@blade04 ~]# cat /tmp/cleanruv.ldif
dn: cn=M3clean,cn=cleanallruv,cn=tasks,cn=config
cn: M3clean
objectclass: extensibleObject
replica-base-dn: dc=passsync,dc=com
replica-id: 2216

[root@blade04 ~]# ldapmodify -x -p 1189 -h localhost -D "cn=Directory Manager" -w Secret123 -avf /tmp/cleanruv.ldif  ldap_initialize( ldap://localhost:1189 )
add cn:
        M3clean
add objectclass:
        extensibleObject
add replica-base-dn:
        dc=passsync,dc=com
add replica-id:
        2216
adding new entry "cn=M3clean,cn=cleanallruv,cn=tasks,cn=config"
modify complete


3) Check that cleanruv has worked out.
[root@blade04 ~]# tail -5 /var/log/dirsrv/slapd-M1/errors

4) Check that there is no attrlist_replace errors.
[root@blade04 ~]# grep -i "attr_replace*.*failed*" /var/log/dirsrv/slapd-*/errors
[root@blade04 ~]# echo $?
1

Marking as VERIFIED.
