Patch fixing the issue "try hard to find free space if database cannot grow"
Note:
- the issue is the same in version 0.9.70 (git)
Situation:
- the database had already grown to its limit (mapsize) in the past
- overflow pages are used heavily as stored values are usually several pages
long
- free space got fragmented
Problem:
- attempt to insert new value results in MDB_MAP_FULL despite there is free
space available
Cause: there is a heursitic in mdb_page_alloc() that gives up searching for
free space chunk if this would take too much time. This is useful when the
database can still grow, as it balances performance with space usage. However,
if the database can no longer grow, it prevents inserting new values.
Solution: detect early on in mdb_page_alloc() if the database can grow, and if
not, let it try hard to search for free space.
Patch: attached

Symas will contribute its RBAC overlay to core
The slapo-rbac overlay is an implementation of the ANSI INCITS 359 Role-Based
Access Control (RBAC) Core.
When instantiated, it intercepts, decodes and enforces specific RBAC policies
per the Apache Fortress RBAC data formats.
The overlay provides a set of extended operations.
They include session create/delete, checkAccess, addActiveRole, dropActiveRole
and sessionRoles.

Symas will contribute its variant overlay to OpenLDAP core
The variant overlay to slapd allows attributes/values to be shared between
several entries. In some ways this is similar to slapo-collect with the
exception that the source and target attributes can be different.

[Issue 9813] New: Incompatibility between remoteauth and ppolicy overlays
by openldap-its＠openldap.org

Hi,
We are planning to use OpenLDAP as a proxy for some users in our Active
Directory servers, using remoteauth overlay.
We want this OpenLDAP instance to also implement an account lockout policy,
preventing the lockout on our internal Active Directory servers.
But there seems to be an incompatibility between remoteauth and ppolicy
overlays : remoteauth won't remote authenticate a user if local userPassword
attribute exists, while ppolicy overlay needs this attribute.
Could there be a configuration parameter in ppolicy to allow lockout
checks/modifications (which seemed to be the default behavior of OpenLDAP
before ITS#7089) ?
I can provide a patch if allowed.
Thanks by advance,
Best regards,
Thierry

[Issue 9827] New: Feature request for module argon2.so to support Argon2i, Argon2d, Argon2id
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9827
Issue ID: 9827
Summary: Feature request for module argon2.so to support
Argon2i, Argon2d, Argon2id
Product: OpenLDAP
Version: 2.6.1
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal

Hi,
This is a feature request.
I would like to be able to chooses between Argon2i, Argon2d and Argon2id in
slappasswd like in argon2 command:
# argon2
Usage: argon2 [-h] salt [-i|-d|-id] [-t iterations] [-m log2(memory in KiB) |
-k memory in KiB] [-p parallelism] [-l hash length] [-e|-r] [-v (10|13)]
Password is read from stdin
Parameters:
salt The salt to use, at least 8 characters
-i Use Argon2i (this is the default)
-d Use Argon2d instead of Argon2i
-id Use Argon2id instead of Argon2i
-t N Sets the number of iterations to N (default = 3)
-m N Sets the memory usage of 2^N KiB (default 12)
-k N Sets the memory usage of N KiB (default 4096)
-p N Sets parallelism to N threads (default 1)
-l N Sets hash output length to N bytes (default 32)
-e Output only encoded hash
-r Output only the raw bytes of the hash
-v (10|13) Argon2 version (defaults to the most recent version,
currently 13)
-h Print argon2 usage
Example:
/usr/local/etc/openldap # /usr/sbin/slappasswd -h "{ARGON2}" -o
module-load="argon2.so i" -s secret
/usr/local/etc/openldap # /usr/sbin/slappasswd -h "{ARGON2}" -o
module-load="argon2.so d" -s secret
/usr/local/etc/openldap # /usr/sbin/slappasswd -h "{ARGON2}" -o
module-load="argon2.so id" -s secret
Best regards

[Issue 10025] New: Add option to disable filtered searches for memberURL groups
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=10025
Issue ID: 10025
Summary: Add option to disable filtered searches for memberURL
groups
Product: OpenLDAP
Version: 2.5.14
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal
Priority: ---
Component: overlays

Reporter: subbarao(a)computer.org
Target Milestone: ---
One of the changes from 2.4 to 2.5 is that dynlist groups are now returned with
(member=memberDN) searches. This is potentially appealing, but even with the
ITS#9929 performance improvements, given the number of dynlist groups we have,
search times are significantly impacted.
We'd like to be able to cleanly disable this feature and exclude dynlist groups
from (member=memberDN) filter consideration. The only way I've found so far is
to patch the dynlist code itself. What I'm currently doing is adding a continue
statement right above this line in dynlist_search():
https://git.openldap.org/openldap/openldap/-/blob/OPENLDAP_REL_ENG_2_5_14...
That way the member searches are excluded, but dynlists otherwise work as
expected.
Here is the dynlist config we're using, just basic support for
groupOfURLs/memberURL:
overlay dynlist
dynlist-attrset groupOfURLs memberURL member
I'd like to request a configurable option to exclude dynlists from
(member=memberDN) searches.

[Issue 9944] New: Reverting an olcDbACLBind statement breaks proxied write operations
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9944
Issue ID: 9944
Summary: Reverting an olcDbACLBind statement breaks proxied
write operations

Version: 2.6.3
Hardware: All

Target Milestone: ---
On a system with olcDbIDAssertBind configured, and proxied authorizations
working correctly, an olcDbACLBind statement was added to the configuration for
lastbind support. However an incorrect identity was in place for the authzid
in the ACL bind statement which caused proxy authorization to fail. The change
was backed out (There was never any change to the olcDbIDAssertBind config
fragment) and after that, all write operations failed instead of being proxied,
with err=80. Restarting slapd fixed the issue, which indicates an underlying
problem in the cn=config db in reverting to the original working state.

REP_CTRLS_MUSTBEFREED when touching rs->sr_ctrls

Assignee: bugs(a)openldap.org
Reporter: ondra(a)mistotebe.net
Target Milestone: ---
Certain parts of the source indicate that rs->sr_ctrls shouldn't be
realloc'd/free'd unless REP_CTRLS_MUSTBEFREED is set, but then other parts of
slapd (slap_ctrl_whatFailed_add, glue_op_search?, ...) and overlays (ppolicy,
syncprov, ...) will blindly overwrite and/or realloc it.
slap_add_control() (an analog of slap_add_controls()) might be useful for this,
possibly alongside some way to free the other data kept around to streamline
the code other users need for correct operation.

[Issue 10026] New: Refresh handling can skip entries (si_dirty not managed properly)

Take MPR plain syncrepl with 3+ providers.
When a provider's own syncrepl session transitions to persist and a it starts a
new parallel session towards another host, that session always has to start as
a refresh. If that refresh serves entries to us, our handling of si_dirty is
not consistent:
- if the existing persist session serves some of these entries to us, we can
"forget" to pass the others to a newly connected consumer
- same if the refresh is abandoned and we start refreshing from a different
provider that might be behind what we were being served (again our consumers
could suffer)
- if we restart, si_dirty is forgotten and our consumers suffer even worse
We might need to be told (at the beginning of the refresh?) what the end state
we're going for is, so we can keep si_dirty on until then. And somehow persist
that knowledge in the DB...
