has this call to the open() function:
if (( fd = open( "lber-test", O_WRONLY|O_CREAT|O_TRUNC|O_BINARY ))
Since O_CREAT is specified, there should be a third argument specifying
the file permissions for the newly created file, but it is missing here,
which may cause the file to be created with permissions based on whatever
noise is in the register or stack position the call reads the third argument
from on a given platform.
Fortunately, it looks like this code may never be compiled, since it's
inside #ifdef HAVE_CONSOLE_H and I can't find anywhere that is set, since
it's not in any AC_CONFIG_HEADER checks in the configure.ac file.

Dears,
When I do following ldapsearch as following :
ldapsearch -x -H ldap://hostname:3891 -b "o=mobistar.be" -s subtree
"(&(objectClass=groupOfUniqueNames)(uniqueMember=uid=jlb,ou=*,o=mobistar.be))"
cn dn
and the DB is containing these entries :
dn: uid=jlb,ou=Test (aa),ou=Partners,o=mobistar.be
dn: ou=Test (aa),ou=Partners,o=mobistar.be
even if this "uid=jlb" isn't member of a group as uniqueMember, it makes slapd
crashing.
I did test it on versions 2.5.7 & 2.5.16, same result --> slapd crashed.
Seems to be related to parenthesis presence in OU attribut.
Is it a bug ?
Thx,
Jean-Luc.

Hi,
I am currently experiencing issues while building a Docker container for
OpenLDAP. I hope that an expert from the community can help me solve my
problem.
Issue 1: Docker Setup
I'm in the process of setting up OpenLDAP within a Docker container on a RHEL 9
base OS. I've attached the Dockerfile I'm using for reference. My primary
concern is that when I run the command RUN slaptest -f /tmp/slapd.conf -F
/etc/openldap/slapd.d -d 1, it fails with mdb_db_open: database
"dc=my-domain,dc=com": dbenv_open(/usr/var/openldap-data).
mdb_db_open: database "dc=my-domain,dc=com" cannot be opened: No such file or
directory (2). Restore from backup!.
Interestingly, slaptest -u seems to work fine. I would greatly appreciate it if
you could review my Dockerfile or provide insights into what might be causing
this issue.
Issue 2: LDAP Migration
Additionally, I'm trying to migrate configuration data from a system using
OpenLDAP 2.4.50 to OpenLDAP 2.5.13. During this process, I encountered the
following error:
csharp
Copy code
olcAuthzRegexp: value #0: keyword <olcAuthzRegexp> missing <regexp> <DN>
argument
slapadd: could not add entry dn="cn=config" (line=1)
Dockerfile.txt
logs_importfile.txt
logs_slaptest.txt
I'm not sure if these issues are related, but I thought it would be best to ask
for your expertise on both matters.
Thank you in advance for your assistance. Your guidance would be greatly
appreciated.

the root user is not supported. If yes, what additional configuration items do
you need to pay attention to when authenticating the root user? Looking forward

Summary: slapd needs a config option for the ssf of an external
security proxy using "proxy protocol v2"
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal
Priority: ---
Component: slapd
Assignee: bugs(a)openldap.org
Reporter: sean(a)teletech.com.au
Target Milestone: ---
Commit 146889f introduced support for the haproxy "proxy protocol v2". A very
welcome addition that allows an external security layer to be implemented. This
implementation is however somewhat hobbled.
Cyrus SASL uses "Security Strength Factors" or "ssf" to determine what
Authentication mechanisms to offer. slapd conveys the implicit security of UNIX
domain sockets to the SASL layer by specifying a non-zero ssf for these
connections. This can be configured with the "olcLocalSSF" config setting.
For implicit/explicit TLS connections, the "olcSecurity: tls=<n>" provides the
cryptographic strength of the TLS layer to the SASL layer.
For an external TLS-terminating proxy, there does not appear to be any way to
inform Cyrus SASL of the presence of TLS security on these proxied connections.
The outcome of this is that PLAIN and EXTERNAL authentication mechanisms are
not offered to clients connecting through the secure proxy.
This can be overcome by weakening the security properties of the SASL layer
with the olcSaslSecProps configuration option, but this weakening will apply to
all clients, not just clients connecting via the secure proxy.
What is required is some way to tell slapd and it's integrated SASL layer about
the presence of TLS encryption on the proxy's input. As a precaution, this
might be restricted to slapd connections in the 127.0.0.0/8 [IPv6:::] address
ranges.

The package Makefile
I am upgrading openLDAP from version 2.4.59 to 2.5.16 and am running into show
stopper issues.
In my environment I am running CLIENT mode only (libldap).
I have tried 2.5.16 with the following combinations:
openSSL version 1.1.1s and 3.0.8
Kernel versions: 5.4.92, 4.19.192 and 2.6.32
Problems described below ONLY happens when connecting with a domain controller
using LDAPS - does NOT happen with LDAP (non-secure).
When I use ANY combination that includes kernel version 4 or 5 along with
openLDAP 2.5.16 I get random lockups to the point where IP connectivity breaks
into and out of the node. And also it is so completely hosed that even issuing
a reboot command from the console completely hangs and does not restart the
node.
The problem happens roughly 50% of the time with openLDAP combined with version
5 kernel but happens noticeably less frequently with the version 4 kernel.
As soon as I kill the process that invokes the connection with openLDAP the
problem clears up.
I invoke the connection with the following function call:
nReturnCode = ldap_sasl_bind( m_pLD, m_ADBind.GetBindDN(), LDAP_SASL_SIMPLE,
&stPassword, NULL, NULL, &nMsgID);
I use simple auth simply because the entire connection is secured with TLS
anyway and there is another functional reason which I cannot go into details
on.
OpenLDAP never returns from the ldap_sasl_bind function call. It hangs
somewhere inside the library but that alone cannot account for the complete
lockup where basic commands like reboot, etc do not work and where all IP
connectivity breaks. It seems it has to be something with openLDAP and the
Linux kernel combined that triggers this issue.
I am hoping that someone who is much more familiar with the libldap part of the
library will pick up on this and be able to determine how to fix this.
As an FYI: I also tried the very first version of 2.5.1 (alpha release) and the
latest 2.6 and the problem happens on those versions as well.
To be clear the problem does NOT happen if I run openLDAP 2.5.16 with Linux
kernel version 2.6.32.
ADDITIONALLY ALL openSSL & kernel combinations works with openLDAP version
2.4.59!
I am attaching the package Makefile to this report. Below is the ldap.conf
contents:
TLS_REQCERT never
TLS_KEY /tmp/ssl/certs/server.pem
TLS_CERT /tmp/ssl/certs/server.pem
TLS_PROTOCOL_MIN 3.1

A server consuming a plain syncrepl session (might be a delta-MMR refresh)
still has to log the entries into accesslog, however that accesslog stops being
capable of serving as a delta-sync source:
- operation entryCSNs will be out-of-order
- the changes logged will not be the intended modifications (e.g. if we fell
back after a conflict, the conflicting entry will be replaced with the other
version, other examples available)
We need to deal with that somehow, at the very least we need to make sure the
consumer will not take them at face value. We could record this in the
accesslog root entry if we can detect when this starts and match it up with the
final cookie, syncprov would still need some tweaks to understand it.
We could mark the entries received this way and make sure delta-consumers treat
them as "poison", as if they were running a plain syncrepl session themselves
(not update contextCSN until that's finished, mark its own accesslog entries
this way, ...). Anything like that needs guarantees that it will clean itself
up once all of the real plain sessions finish otherwise we've lost delta-sync
altogether.
A different approach might or might not be needed for live delta-persist
sessions replicating from a refreshing provider, but at least that syncprov has
a way of detecting this live if it chooses to.

If two or more updates are spread across several providers before they have a

content regardless of the order in which they arrive.
One example that is broken at the moment:
- (csn a) server 1 accepts a modify
- (csn b) server 2 accepts a delete on the same DN
- (csn c) server 2 accepts an add on that DN again
If a replica receives the actions in the order bca vs. abc, the content of the
entry will be different even though the final CSN set is the same -> they will
never converge. The ordering 'bac' also needs to result in eventual
convergence, even if it means a refresh or replication from either provider
stalling temporarily?

When configured to do dynamic "member" expansion, i.e.:

dynlist-attrset groupOfURLs memberURL member
Any query against an object that would trigger this expansion will incur a
penalty while dynlist does the expansion work even if there was no request for
the member attribute.
Currently that can be worked around by specifying the manageDSAit control when
doing a search on the object, but this may not be feasible for some client
applications and additionally other directory servers do not do this expansion
for their dynamic group implementations unless the underlying configured
attribute is explicitly requested.
We've already implemented this in dynlist for the memberOfAD case, we should do
it here as well.

- just merge the whole thing?
- are there components that link liblutil but _not_ libldap?
- build liblutil as PIC (take a minor performance hit when linked into
programs?)
- build liblutil twice (liblutil.a and liblutil_pic.a)
- symlink liblutil sources into libldap build dir, like libldap_r does with
libldap
- both of these last options require checking whether executables can call
the PIC symbols safely (if some symbols are used by both library and program
code)
Nice-to-have for 2.5, I'd say more likely for 2.6 at this point.

Summary: Move all replication consumer code into its own
overlay
Product: OpenLDAP
Version: 2.5
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: overlays
Assignee: bugs(a)openldap.org
Reporter: quanah(a)openldap.org
Target Milestone: ---
(In relation to a discussion about slapo-chain)
<hyc> anyway, the nicer ting to fix would be in 2.5, push all of the repl
consumer code into its own overlay
<hyc> in that case, updateref would be processed wherever the overlay was
configured
<hyc> so no longer tied to the frontend
<hyc> it would also make it more feasible to have multiple different consumer
configs in a single DB, each with their own provider URL (and thus their own
updateref)
<hyc> I would think we can get rid of the update ref directive entirely, just
point all writes to that consumer's provider.

From a past discussion with hyc on 2.5 items:
[13:57] <hyc> there's a nagging problem though, pcache's entry_release function
needs to distinguish between its backend actually freeing the entry, or being a
no-op
[13:57] <hyc> so it can decide whether to return success or continue
[13:58] <hyc> the patch to translucent sidesteps the question, by avoiding
other overlays
[13:58] <hyc> but we need to revisit this in 2.5

Next I rebuild openldap adding flags to configure step:
./configure CFLAGS=-g
When I run slapd in new image:
slapd -h 'ldap://0.0.0.0:10389 ldaps://0.0.0.0:10536
ldapi://%2Fopt%2Fldap%2Fldapi' -F /opt/ldap//openldap/etc/openldap/slapd.d
all working well and I didn't get segementation fault.
Can someone tell me what I'm doing wrong and how to investigate the problem?
Regards
BS

Issue ID: 10127
Summary: Thread Safety in LMDB with MDB_NOTLS and Readonly
Cursors
Product: LMDB
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal
Priority: ---
Component: liblmdb
Assignee: bugs(a)openldap.org
Reporter: xiaoya2wei(a)gmail.com
Target Milestone: ---
Greetings LMDB Community,
I am delving into the thread-safety aspects of LMDB, specifically regarding the
use of readonly cursors across multiple threads. With the MDB_NOTLS flag
enabled, which disables thread-local storage, my understanding is that readonly
transactions may be shared between threads, provided there is proper
synchronization to prevent concurrent access.
Building upon this, I seek clarity on the following: Can multiple threads
safely access a single readonly cursor derived from such a synchronized
readonly transaction when MDB_NOTLS is enabled?
Upon reviewing the LMDB source code, I noticed that cursors are tied to
transactions (see mdb.c#L1335). This suggests that if threads can synchronously
share a transaction, they might also share a cursor associated with it for data
retrieval.
I recognize my analysis might be superficial, and I'm open to corrections. Your
insights on this matter would be greatly appreciated to enhance my
understanding of LMDB's concurrency mechanisms.
Thank you in advance for your assistance!

--- Comment #8 from Ondřej Kuzník <ondra(a)mistotebe.net> ---
For comparison, using deltasync (and sortvals!) makes the consumer take a
similar amount of CPU time (about +50-90 % on the provider's) to process the
10k value additions, just like Ryan noted earlier.
On the other idea, no clue on whether we can somehow limit the amount of data
queued up without severely impairing replication progress.

--- Comment #7 from Ondřej Kuzník <ondra(a)mistotebe.net> ---
Making attr_cmp do a linear sweep for sortvals attributes (instead of the
quadratic match it has to do right now) makes the consumer 7-8x slower than a
provider across the board with the environment provided. I might have expected
something like 3-4x but that's out of scope for this particular ITS.

attr_cmp should check the attribute is a sortval and if so, should diff without
resolving to a double loop.

May be possible to improve diff code for standard syncrepl to improve
performance on the consumer side if the attribute is sorted via sortvals, needs
investigation.
