Doc Text:	Cause: Configuring the directory server to use Managed Entry and DNA, and running a series of search and update operations to exercise and verify those plugins, while running the directory server using valgrind. Consequence: valgrind reports memory errors and leaks. Fix: Make sure memory is used correctly and deleted correctly. Result: valgrind should report no problems related to Managed Entry and DNA.

Description Nathan Kinder 2012-06-08 17:49:34 EDT

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/313

1) the ldbm instance dse preop delete callback deletes the entry and dn caches - some other plugins called after this attempt to access those caches

2) normalize_mods2bvals allocs the berval twice in the dn syntax case

3) mep_parse_config_entry allocs value but does not free it

4) dna_be_txn_pre_op can goto bail: in certain cases and attempt to free NULL smods

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 3 RHEL Product and Program Management 2012-07-10 19:01:04 EDT

This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.

Comment 5 Sankar Ramalingam 2013-01-28 12:04:50 EST

Request you to add steps to verify bugzilla.

Comment 6 Rich Megginson 2013-01-29 13:26:38 EST

1) setup the directory server to run under valgrind
2) run the managed entry and DNA tests from TET
3) the valgrind output should not report leaks or errors in normalize_mods2bvals(), mep_parse_config_entry(), dna_be_txn_pre_op()
