There are some unused variables in librewrite that need fixing, and one case
where an rc is set but never returned which also needs addressing.

Created attachment 700
--> https://bugs.openldap.org/attachment.cgi?id=700&action=edit
test script copied from test022-ppolicy and modified to show the trouble
Hello,
I'm doing a OpenLDAP test with a master/slave replication configuration
including ppolicy overlay. I would like to enable password change from the
slave replica with chain overlay, in order to validate the ppolicy
olcPPolicyForwardUpdates attribute to TRUE. I'm using LDAPS from slave to
master with SASL External authentication with client certificate. The client
certificate correspond to a user DN entry with "manage" rights on the master
server (the same used for the replication). This user DN has authzTo attribute
in order to match the correct PROXYAUTHZ request from its dn to user DN.
All of this configuration works on replica when i do first a failed
authentication (err=49) on replica. The pwdFailureTime value is updated on the
DN entry from replica to slave normally. I'm also able to do after some self
entry update on some attribute such as password or others from replica to
master.
But the weird behavior is that i need to run first an failed authentication,
otherwise if i try to change attribute on the slave server, it respond an
err=80 "Error: ldap_back_is_proxy_authz returned 0, misconfigured URI?". The
only way to retrieve correct behavior is to restart slapd, and redo one failed
authentication first. It seems that the chain overlay do not connect the master
server at startup.
I've done a modification of test script test022-ppolicy to test022-policy-chain
which use the same LDIF source and show the problem of modification on the
consumer not "relayed" to the supplier if a fail operation is not done before.
Regards

--------------------
The two cores seem to be the same, only the difference between modify and
delete request.
Both are considered to cause a segmentation fault because the value of the
third parameter(*1) of test_filter is invalid.
The third parameter(*1) of test_filter should be an address, like the source
below.
Excerpt from filterentry.c:
--------------------
60 int
61 test_filter(
62 Operation *op,
63 Entry *e,
64 Filter *f )
** the third parameter of test_filter
65 {
66 int rc;
67 Debug( LDAP_DEBUG_FILTER, "=> test_filter\n", 0, 0, 0 );
68
69 if ( f->f_choice & SLAPD_FILTER_UNDEFINED ) {
** referenced here
70 Debug( LDAP_DEBUG_FILTER, " UNDEFINED\n", 0, 0, 0 );
--------------------
Version-Release number of selected component (if applicable):
How reproducible:
Two times
Steps to Reproduce:
Unknown
Actual results:
slapd crashes with a segmentation fault and a core is outputted.
Expected results:
slapd doesn't crash and a core isn't outputted.
Thanks!

[23:34] <hyc> ok, so far heap profile shows that memory use during refresh is
normal
[23:35] <hyc> not wonderful, but normal. mem usage grows because we're
recording the present list while receiving entries in the refresh
[23:36] <hyc> I'm seeing for 1.2GB of data about 235MB of presentlist
[23:36] <hyc> which is pretty awful, considering presentlist is just a list of
UUIDs
[23:36] <hyc> being stored in an avl tree
[23:37] <hyc> a btree would have been better here, and we could just use an
unsorted segmented array
[23:42] <hyc> for the accumulation phase anyway. we need to be able to lookup
records during the delete pphase
[00:05] <hyc> this stuff seriously needs a rewrite
[01:13] <hyc> 2.8M records x 16 bytes per uuid so this should be no more than
48MB of overhead
[01:13] <hyc> and instead it's 3-400MB

Had an incident today where slapd stopped after the following assert was
triggered in syncprov.c:
1655 rc = tavl_insert( &sl->sl_entries, se, syncprov_sessionlog_cmp,
avl_dup_error );
1656 assert( rc == LDAP_SUCCESS );
This was due to the same entry being inserted into the sessionlog a second time
without the prior instance having been removed.
