[Issue 9421] New: SIGSEGV in the MMR synchro

https://bugs.openldap.org/show_bug.cgi?id=9421
Issue ID: 9421

We are in the process of migrating from a single outdated node to an up to date
MMR cluster. Through this process we write LSC synchronizations from the old
server to the new server so we can keep the old server around.
Our preliminary tests show that when LSC hammers the ldap using multiple
threads while another node is included in the replication, we get segmentation
faults with the following backtrace:

If we take down the second node, we cannot reproduce the segfaults anymore.
Let me know if we can provide more information (we can't provide the core dump
since it's full of passwords).

Add support for the HAProxy proxy protocol v2:

This will allow slapd to receive and act upon client addresses when operating
behind a NAT'ing load balancer or proxy server which would otherwise obscure
the true client address.
Patch will be submitted as a pull request on gitlab.
The submitted pull request is derived from OpenLDAP Software. All of the

ldapsearch debug log
When -Z is passed to an OpenLDAP utility, it will try to establish a TLS
connection with StartTLS, and in case it fails to do so it should continue
without the TLS layer.
OpenLDAP version:
openldap-2.4.56-4.fc34.x86_64 (but it also doesn't work on older versions too)
How reproducible:
Always
Steps to Reproduce:
1. Run `ldapsearch ...' against a server and see successful operation result.
2. Run `ldapsearch -Z ...' against a server whose certificate is not trusted
(e.g. a hostname mismatch) and observe it fails to connect as in point 1.
Actual results:
~~~
ldap_start_tls: Connect error (-11)
additional info: TLS: hostname does not match CN in peer certificate
# and it hangs there
~~~
Expected results:
The line
~~~
ldap_result: Can't contact LDAP server (-1)
~~~
is not present and the utility successfully continues with plain LDAP protocol
as expected.
Additional info:
I'm attaching a full debug log (-d -1) to this bug.

[Bug 9199] New: Disable IPv6 makes listener work on IP address but hostname or localhost
by openldap-its＠openldap.org

Hi,
We're compiling 2.4.49 on CentOS8.
Make test fails at "test000-rootdse" with error Can't contact LDAP server.
Debug log shows error "Address already in use".
We're quite sure the port (9011) is not in use.
Starting slapd with test command verified the error:
../servers/slapd/slapd -f testrun/slapd.1.conf -h ldap://localhost:9011
Found that it's okay to start slapd if listener URL is using IP address
instead.
Checked ldap_url_parse* call may not work as expected with V6 disabled
(configure option --disable-ipv6).
Re-do configuration and make without "--disable-ipv6" works as expected.
Would you help? Thanks.

[Bug 9192] New: slapo-rwm: assert triggered with invalid UUID filter
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9192
Bug ID: 9192
Summary: slapo-rwm: assert triggered with invalid UUID filter
Product: OpenLDAP
Version: 2.4.48

Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: overlays
Assignee: bugs(a)openldap.org

slapo-rwm triggers an assert when a filter with an invalid UUID syntax is used.
For example:
/opt/symas/bin/ldapsearch -x -H ldaps://ldap0.example.com -D
"cn=admin,dc=example,dc=com" -W -b dc=example,dc=com
idmUUID=b58540b2-f16c-41c9-8147-83068004dd0a,ou=People,dc=example,dc=com
Enter LDAP Password:
# extended LDIF
#
# LDAPv3
# base <dc=example,dc=com> with scope subtree
# filter:
idmUUID=b58540b2-f16c-41c9-8147-83068004dd0a,ou=People,dc=example,dc=com
# requesting: ALL
#
The above search will trigger an assert. Note that idmUUID is a custom
attribute defined as:
# idmUUID
attributetype ( 1.3.6.1.4.1.29179.2.3.3
NAME 'idmUUID'
DESC 'RFC4122 Univeral Unique Identifier for idM'
EQUALITY uuidMatch
SYNTAX 1.3.6.1.1.16.1
SINGLE-VALUE )
which is using the RFC4530 definition for UUID.
On the slapd side, we see:

[Issue 9422] New: add #define LDAP_OPT_X_TLS_PROTOCOL_TLS1_3 to ldap.h
by openldap-its＠openldap.org

I'm not sure whether naively adding this line to ldap.h would be correct:
#define LDAP_OPT_X_TLS_PROTOCOL_TLS1_3 ((3 << 8) + 4)

[Bug 9197] New: slapd-ldap/slapo-chain hits error 80 after idletimeout
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9197
Bug ID: 9197
Summary: slapd-ldap/slapo-chain hits error 80 after idletimeout
Product: OpenLDAP
Version: 2.5
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: backends
Assignee: bugs(a)openldap.org
Reporter: quanah(a)openldap.org
Target Milestone: ---
From a customer:
In order to communicate via the LB managed writable ldap, we have to ensure
that an idle connection is periodically refreshed. If we do not, the LB will
silently drop the connection after 5 minutes.
Therefore to combat that I set an olcIdleTimeout on the writable server so that
the chain cached connections will be removed before the LB timeout hits.
However the slapo-ldap client goes into CLOSE_WAIT state, which causes
subsequent ldapmodify updates being brokered by the read only instance to fail
with err=80. There appear to be a few bugs filed on this in the past against
slapd-ldap, but it's not clear if we may be hitting the same issue, or if this
is a new one.
I've also connected the read only instances directly to the writable ldap
instances and the CLOSE_WAIT issue persists, so I don't believe the CLOSE_WAIT
issue is caused by the LB
These were the other threads I found as I started looking for this problem,
these are using the ldap-proxy though I think:
https://www.openldap.org/lists/openldap-technical/201301/msg00323.html
http://www.openldap.org/lists/openldap-software/201004/msg00060.html
https://www.openldap.org/lists/openldap-bugs/200412/msg00029.html
The LB we have seems to be set to forget connections that last over 5 min per
the setting, so the 240:10:30 seemed like it should have worked and I just
thought it wasn't working because in the man page the text "Only some systems
support the customization of these values" is present. however after setting
keepalive to 60:10:30 did I maintain a stable connection, so there may be other
network settings at play I'm not aware of.
