Summary: Feature request for module argon2.so to support
Argon2i, Argon2d, Argon2id
Product: OpenLDAP
Version: 2.6.1
Hardware: All
OS: All
Status: UNCONFIRMED

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

A program using libldap will crash on exit after using SSL connection.
How to reproduce on CentOS 9:
Uncomment the following lines in /etc/pki/tls/openssl.cnf:
[provider_sect]
legacy = legacy_sect
[legacy_sect]
activate = 1
Run the command (you must enter a valid LDAP server address):
python3 -c "import ldap; ldap.initialize('ldaps://<LDAP SERVER
ADDRESS>').whoami_s()"
Another example (no server required):
python3 -c "import ctypes;
ctypes.CDLL('libldap.so.2').ldap_pvt_tls_init_def_ctx(0)"
Results:
Segmentation fault (core dumped)

The problem is that ldap_int_tls_destroy() is called after the clean up of
libssl.
On program exit, at first default_context_int is cleaned up (OPENSSL_cleanup()
was registered with atexit()):
0 ossl_lib_ctx_default_deinit () at crypto/context.c:196
1 OPENSSL_cleanup () at crypto/init.c:424
2 OPENSSL_cleanup () at crypto/init.c:338

6 0x00007ffff785befc in __libc_start_main_impl (main=0x55555556aa20 <main>,
argc=4, argv=0x7fffffffe2c8, init=<optimized out>, fini=<optimized out>,
rtld_fini=<optimized out>, stack_end=0x7fffffffe2b8) at ../csu/libc-start.c:409
7 0x000055555556b575 in _start ()
Then ossl_lib_ctx_get_data() tries to use default_context_int.lock, which is
NULL. ldap_int_tls_destroy() is called by ldap_int_destroy_global_options(),
registered by "__attribute__ ((destructor))".
It seems that shared library destructors are always called before functions
registered with atexit().
A solution may be to modify libraries/libldap/init.c to use atexit() instead of
"__attribute__ ((destructor))". atexit() manual page says: "Since glibc 2.2.3,
atexit() can be used within a shared library to establish functions that are
called when the shared library is unloaded.".
Functions registered with atexit() are called in the reverse order of their
registration, so libssl must by initialized before libldap. If the order is
wrong, libldap should detect it somehow and exit with abort().

Summary: MDB_PAGE_FULL with master3 (encryption) because there
is no room for the authentication data (MAC)

Created attachment 915
--> https://bugs.openldap.org/attachment.cgi?id=915&action=edit
proposed patch
Hello,
on master3, using the encryption at rest feature,
I am testing as follow:
- on a new named database, i set the encryption function with
mdb_env_set_encrypt(env, encfunc, &enckey, 32)
- note that I chose to have a size parameter (The size of authentication data
in bytes, if any. Set this to zero for unauthenticated encryption mechanisms.)
of 32 bytes.
- I add 2 entries on the DB, trying to saturate the first page. I chose to add
a key of 33 Bytes and a value of 1977 Bytes, so the size of each node is 2010
Bytes (obviously the 2 keys are different).
- This passes and the DB has just one leaf_pages, no overflow_pages, no
branch_pages, an a depth of 1.
- If I add one byte to the values I insert (starting again from a blank DB),
then , instead of seeing 2 overflow_pages, I get an error : MDB_PAGE_FULL.
- this clearly should not have happened.
- Here is some tracing :
add to leaf page 2 index 0, data size 48 key size 7 [74657374646200]
add to leaf page 3 index 0, data size 1978 key size 33
[000000000000000000000000000000000000000000000000000000000000000000]
add to branch page 5 index 0, data size 0 key size 0 [null]
add to branch page 5 index 1, data size 0 key size 33
[000000000000000000000000000000000000000000000000000000000000000000]
add to leaf page 4 index 0, data size 1978 key size 33
[000000000000000000000000000000000000000000000000000000000000000000]
add to leaf page 4 index 1, data size 1978 key size 33
[020202020202020202020202020202020202020202020202020202020202020202]
not enough room in page 4, got 1 ptrs
upper-lower = 2020 - 2 = 2016
node size = 2020
Looking at the code, I understand that there is a problem at line 9005 :
} else if (node_size + data->mv_size > mc->mc_txn->mt_env->me_nodemax) {
where me_nodemax is incorrect, as it is not taking into account that some bytes
will be needed for the MAC authentication code, which size is in
env->me_esumsize.
me_nodemax is calculated at line 5349:
env->me_nodemax = (((env->me_psize - PAGEHDRSZ ) / MDB_MINKEYS) & -2)
- sizeof(indx_t);
So I substract me_esumsize with a "- env->me_esumsize" here:
env->me_nodemax = (((env->me_psize - PAGEHDRSZ - env->me_esumsize) /
MDB_MINKEYS) & -2)
- sizeof(indx_t);
I also substract it from me_maxfree_1pg in the line above, and in pmax in line
10435.
I do not know if my patch is correct, but it solves the issue.
Maybe there are other places in the code where the me_esumsize should be
substracted from the available size. By example, when calculating the number of
overflow pages in OVPAGES, it does not take into account me_esumsize, but I
think it is ok, because there is only one MAC for the entire set of OV pages,
and there is room for it in the first OV page.
See the attached proposed patch.

Summary: Add list of peerSIDs to consumer cookie to reduce
cross traffic
Product: OpenLDAP
Version: 2.5

Status: UNCONFIRMED
Severity: normal

Component: slapd
Assignee: bugs(a)openldap.org
Reporter: quanah(a)openldap.org
Target Milestone: ---
If we add a list of peersids to the cookie, each consumer can tell the
providers who else the consumers talk to and then the provider can omit sending
updates to that consumer, originating from those peers
There's some special handling needed if a connection dies
If a consumer loses one of its peer connections, and after N retries is still
not connected, it should send a new cookie to its remaining peers saying
"here's my new peer list" with the missing one removed. Likewise, if a retry
eventually connects again, it can send a new cookie again
Make that peer list reset configurable in the syncrepl config stanza. This can
help account for end admin knowledge that some links may be more or less stable
than other ones.
The idea here is that if one of your other peers can still see the missing
peer, they can start routing updates to you again
It should abandon all existing persist sessions and send a new sync search with
the new cookie to all remaining peers
For consumer side, also means adding the sid for a given provider into the
syncrepl stanza to save on having to try and discover the peer sid.

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
