https://bugs.openldap.org/show_bug.cgi?id=9471
Issue ID: 9471
Summary: Add RBAC overlay to core
Product: OpenLDAP
Version: 2.5
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: overlays

Target Milestone: ---
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.

[Issue 9473] New: Add variant overlay to core

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 9278] New: liblmdb: robust mutexes should not be unmapped
by openldap-its＠openldap.org

Issue ID: 9278
Summary: liblmdb: robust mutexes should not be unmapped
Product: LMDB
Version: unspecified
Hardware: All
OS: FreeBSD
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: liblmdb

Created attachment 736
--> https://bugs.openldap.org/attachment.cgi?id=736&action=edit
A possible workaround
We recently noticed that lmdb would have the memory region containing the
robust mutex unmapped on mdb_env_close0():
munmap((void *)env->me_txns,
(env->me_maxreaders-1)*sizeof(MDB_reader)+sizeof(MDB_txninfo));
Note that if this is the last unmap for a robust mutex, the FreeBSD
implementation would garbage-collect the mutex, making it no longer visible to
other processes. As the result, a second instance of the attached test.c (from
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244493 with minor changes)
would trigger the assertion at mdb_txn_begin() because the acquisition of the
mutex would return 22 (EINVAL), because the mutex appeared to be a robust
mutex, but was invalid.
The attached lmdb.diff is a possible workaround for this (it would skip
unmapping when setting up the robust mutex for the first time).

[Issue 9506] New: dynlist: member expansion when member attribute not requested
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9506
Issue ID: 9506
Summary: dynlist: member expansion when member attribute not
requested
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: ---
When configured to do dynamic "member" expansion, i.e.:
overlay dynlist
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.

[Bug 9244] New: API calls blocking after async connect
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9244
Bug ID: 9244
Summary: API calls blocking after async connect
Product: OpenLDAP
Version: 2.4.49
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: libraries
Assignee: bugs(a)openldap.org
Reporter: ryan(a)openldap.org
Target Milestone: ---
Created attachment 721
--> https://bugs.openldap.org/attachment.cgi?id=721&action=edit
async connect test without TLS
My understanding of LDAP_OPT_CONNECT_ASYNC is that the attached program should
not block. If the connection does not establish fast enough, the bind call is
supposed to return LDAP_X_CONNECTING.
(At least that's how I understand it, based on the original behaviour (circa
2.4.23 up to 2.4.40) as well as the bind loop in back-meta. On the other hand,
the man page does "Subsequent calls to library routines will poll for
completion of the connect before performing further operations" which might be
interpreted as meaning they would block...)
In current releases it does block, as demonstrated by strace on Linux (latency
added using 'tc qdisc'):
[...]
connect(3, {sa_family=AF_INET, sin_port=htons(389),
sin_addr=inet_addr("192.168.1.204")}, 16) = -1 EINPROGRESS (Operation now in
progress)
write(3, "0\f\2\1\1`\7\2\1\3\4\0\200\0", 14) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLOUT|POLLERR|POLLHUP}], 1, -1) = 1 ([{fd=3,
revents=POLLOUT}])
write(3, "0\f\2\1\1`\7\2\1\3\4\0\200\0", 14) = 14
poll([{fd=3, events=POLLIN|POLLPRI}], 1, -1) = 1 ([{fd=3, revents=POLLIN}])
read(3, "0\f\2\1\1a\7\n", 8) = 8
read(3, "\1\0\4\0\4\0", 6) = 6
write(2, "OK: ldap_simple_bind_returned 0 "..., 42OK: ldap_simple_bind_returned
0 (Success)
) = 42
[...]
As discussed in IRC, I believe I bisected this down to commit ae6347bac, from
bug 8022. The reasoning is sound, but ldap_int_open_connection does not
actually return -2, only -1 or 0.
The patch is simple enough, but I'm also looking at some later commits that
were probably done to work around this, and might not be needed now (bug 8957,
bug 8968, bug 8980). Also need to test all setups thoroughly (ldap, ldaps,
STARTTLS, not to mention back-meta/asyncmeta).
I also notice that LDAP_OPT_CONNECT_ASYNC is not effective unless
LDAP_OPT_NETWORK_TIMEOUT is also set. It might be intentional, but the man page
doesn't mention this specifically, and I don't see why it would be necessary...

[Bug 9229] New: Make liblutil usable by libldap
by openldap-its＠openldap.org
https://bugs.openldap.org/show_bug.cgi?id=9229
Bug ID: 9229
Summary: Make liblutil usable by libldap
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: ---
Component: build
Assignee: bugs(a)openldap.org
Reporter: ryan(a)openldap.org
Target Milestone: ---
liblutil is a static library (non-PIC) and so cannot be linked into shared
objects, however we have several use cases for reusing its code in libldap.
Some options:
- moving more code from liblutil to libldap
- 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.

OpenLDAP master fails to build against OpenSSL 3.0 alpha when "no-deprecated"
is specified.
Currently hitting these errors:
./.libs/libldap.so: undefined reference to `SSL_get_peer_certificate'
./.libs/libldap.so: undefined reference to `PEM_read_bio_DHparams'
./.libs/libldap.so: undefined reference to `ERR_get_error_line'
./.libs/libldap.so: undefined reference to `DH_free'
./.libs/libldap.so: undefined reference to `SSL_CTX_set_tmp_dh'
Notes:
SSL_get_peer_certificate is SSL_get1_peer_certificate in 3.0.0
SSL_CTX_set_tmp_dh should be replaced as follows:
# define SSL_CTX_set_tmp_dh(ctx,dh) \
SSL_CTX_ctrl(ctx,SSL_CTRL_SET_TMP_DH,0,(char *)(dh))
Have to dig deeper for:
PEM_read_bio_DHparams
ERR_get_error_line
DH_free

OpenSSL no longer supports the 1.0.2 series and specifically notes it should
not be used:
"All older versions (including 1.1.0, 1.0.2, 1.0.0 and 0.9.8) are now out of
support and should not be used."
Currently configure checks for 1.0.2 or higher.
OpenSSL 1.1.1 is supported through 11 Sep 2023.

[Issue 9496] New: Some writes missing from database

Summary: Some writes missing from database

Assignee: bugs(a)openldap.org

Target Milestone: ---
With the attached test program, some of my database writes appear not to
actually be written to the database. For example, a run may look like this:
$ ./run.sh
All done.
All finished
1802 test.txt
foo_200 is missing
bar_200 is missing
foo_404 is missing
bar_404 is missing
foo_407 is missing
bar_407 is missing
The script that I am using to run the program is below. This is using
mdb.master 52bc29ee2efccf09c650598635cd42a50b6ecffe on Linux, with an ext4
filesystem.
Is this an LMDB bug, or is there a bug in my code?
Thanks
Ian
