[Issue 9880] New: reqStart filter with trailing zeros is truncated, which breaks certain searches
by openldap-its＠openldap.org 09 Feb '23

https://bugs.openldap.org/show_bug.cgi?id=9880 Issue ID: 9880 Summary: reqStart filter with trailing zeros is truncated, which breaks certain searches Product: OpenLDAP Version: 2.5.12 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: subbarao(a)computer.org Target Milestone: --- Note: ITS#9358 seems to address this very issue, but it doesn't seem to help this particular case. Certain range searches with reqStart on the changelog don't work as expected. For example: (!(reqStart<=20220707123456.000000Z)) The idea here is to grab all entries strictly greater than the timestamp. But slapd truncates zeros in this filter, rewriting it to: (!(reqStart<=20220707123456Z)) As a result, the reqStart=20220707123456.000000Z entry is the first match since it is greater than 20220707123456Z, which is not the desired behavior. I was able to reproduce this issue on 2.5.12 as follows: 1) Start the test043-delta-syncrepl test, let it run almost to the end so that it makes many changes, and then hit ^Z to suspend the script. I waited until one of the last occurrences of "Waiting 7 seconds for syncrepl to receive changes". 2) pkill -CONT -f slapd to restart slapd (but not the test script) 3) ldapsearch -x -h localhost:9011 -b cn=log objectclass=top | grep '^dn:.*.000000Z' Look for a change with all trailing zeros. It's not as rare as one might think, I saw at least one trailing-zeros change in two consecutive runs of the test script. I suppose you could also just create an entry with all trailing zeros in the accesslog :-) 4) Run a range search to only return changes after that change (I used -z 1 and -s one so that it would only give me one result): ldapsearch -x -z 1 -h localhost:9011 -b cn=log -s one '(!(reqStart<=20220708012121.000000Z))' If you see the same entry, then the problem is present. 5) Even if you can't have an accesslog entry with all trailing zeros, you can still do the above search verbatim and look at the slapd log file testrun/slapd.1.log: 62c7873f.145b4396 0x7fabf14c9700 conn=1011 op=1 SRCH base="cn=log" scope=1 deref =0 filter="(!(reqStart<=20220708012121Z))" The filter being rewritten in the server log seems to indicate that trailing zeros are being truncated somewhere. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9365] New: Mem leaks with Æ-DIR providers

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.

This is partly identical with ITS#9642 and a similar approach would work. Except that changes our module facing ABI so might not be something we can backport. For the streams we can't, we might have to change the test to make the server not idle. -- 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

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.
