[Issue 9365] New: Mem leaks with Æ-DIR providers
by openldap-its＠openldap.org 03 Oct '22

https://bugs.openldap.org/show_bug.cgi?id=9365 Issue ID: 9365 Summary: Mem leaks with Æ-DIR providers Product: OpenLDAP Version: 2.4.53 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: michael(a)stroeder.com Target Milestone: --- Created attachment 772 --> https://bugs.openldap.org/attachment.cgi?id=772&action=edit valgrind output on openSUSE Tumbleweed x86_64 An Æ-DIR installation with self-compiled OpenLDAP 2.4.53 on Debian (now buster) has memory leak issues on the Æ-DIR providers. The read-only consumers do not have this issue. The provider config is more complex with more overlays and more ACLs. In this production deployment slapd is automatically restarted (by monit) when memory consumption reaches 80%. Thus monitoring clearly shows a frequent saw tooth pattern. I've also tested on openSUSE Tumbleweed x86_64 with a RE24 build [1] by running slapd under control of valgrind for a couple of minutes continously sending simple bind operations (additional to the monitoring and other back-ground jobs running). Find valgrind output of my first attempt attached. Does that make sense at all? -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9524] New: Removing last entry in database triggers MDB_PROBLEM
by openldap-its＠openldap.org 21 Sep '22

https://bugs.openldap.org/show_bug.cgi?id=9524 Issue ID: 9524 Summary: Removing last entry in database triggers MDB_PROBLEM Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: kriszyp(a)gmail.com Target Milestone: --- With a fresh database, if you have have an open read transaction, and you create a new entry in a write transaction and commit it, and then create a new transaction and delete that entry, when you commit, it will return an MDB_PROBLEM from approximately line 4408 from the mt_loose_count/dirty_list check. This seems to occur on mdb.master3, but not mdb.master. Here is a minimal example/test-case of how to reproduce: MDB_env* env; mdb_env_create(&env); int rc, flags = 0; mdb_env_open(env, "test", flags, 0664); MDB_txn* readonly_txn; mdb_txn_begin(env, nullptr, MDB_RDONLY, &readonly_txn); MDB_txn* txn; MDB_dbi dbi; mdb_txn_begin(env, nullptr, 0, &txn); mdb_dbi_open(txn, nullptr, MDB_CREATE, &dbi); MDB_val val; val.mv_data = (void*) "test"; val.mv_size = 4; mdb_put(txn, dbi, &val, &val, 0); mdb_txn_commit(txn); mdb_txn_begin(env, nullptr, 0, &txn); mdb_del(txn, dbi, &val, nullptr); rc = mdb_txn_commit(txn); // this returns MDB_PROBLEM (let me know if this should be submitted differently) -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9358] New: back-mdb may return accesslog entries out of order
by openldap-its＠openldap.org 01 Sep '22

https://bugs.openldap.org/show_bug.cgi?id=9358 Issue ID: 9358 Summary: back-mdb may return accesslog entries out of order Product: OpenLDAP Version: 2.4.53 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- back-mdb will usually return search entries in entryID order, but may do a dn traversal instead if the count of children is smaller than the count of search filter candidates. The RDNs are sorted in length order, not lexical order. For accesslog, all RDNs are of equal length but if they have trailing zeroes, the generalizedTime normalizer truncates them. Changing their lengths causes accesslog's timestamp-based RDNs to sort in the wrong order. The least intrusive fix is to override the syntax/normalizer for reqStart and reqEnd attributes to not truncate trailing zeroes. -- You are receiving this mail because: You are on the CC list for the issue.
