[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... -- You are receiving this mail because: You are on the CC list for the bug.

[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. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 9189] New: Add GSSAPI channel-bindings support

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9189 Bug ID: 9189 Summary: Add GSSAPI channel-bindings support Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: iboukris(a)gmail.com Target Milestone: --- Recently MS has announce they plan to enforce channel-bindings for LDAP over TLS (ADV190023). To support it on client side, we need to pass "tls-endpoint" bindings (RFC 5929) to the SASL plugin, and make use of that in GSSAPI.

[Bug 9204] New: slapo-constraint allows anyone to apply Relax control

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9204 Bug ID: 9204 Summary: slapo-constraint allows anyone to apply Relax control Product: OpenLDAP Version: 2.4.49 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: ryan(a)openldap.org Target Milestone: --- slapo-constraint doesn't limit who can use the Relax control, beyond the global limits applied by slapd. In practice, for many modifications this means any configured constraints are advisory only. In my opinion this should be considered a bug, in design if not implementation. I expect many admins would not read the man page closely enough to realize the behaviour does technically adhere to the letter of what's written there. Either slapd should require manage privileges for the Relax control globally, or slapo-constraint should perform a check for manage privilege itself, like slapo-unique does. Quoting ando in https://bugs.openldap.org/show_bug.cgi?id=5705#c4: > Well, a user with "manage" privileges on related data could bypass > constraints enforced by slapo-constraint(5) by using the "relax" > control. The rationale is that a user with manage privileges could be > able to repair an entry that needs to violate a constraint for good > reasons. Note that the user: > > - must have enough privileges to do it (manage) > > - must inform the DSA that intends to violate the constraint (by using > the control) but such privileges are currently not being required. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 9211] New: Relax control is not consistently access-restricted

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9211 Bug ID: 9211 Summary: Relax control is not consistently access-restricted Product: OpenLDAP Version: 2.4.49 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ryan(a)openldap.org Target Milestone: --- The following operations can be performed by anyone having 'write' access (not even 'manage') using the Relax control: - modifying/replacing structural objectClass - adding/modifying OBSOLETE attributes Some operations are correctly restricted: - adding/modifying NO-USER-MODIFICATION attributes marked as manageable (Modification of non-conformant objects doesn't appear to be implemented at all.) In the absence of ACLs for controls, I'm of the opinion that all use of the Relax control should require manage access. The Relax draft clearly and repeatedly discusses its use cases in terms of directory _administrators_ temporarily relaxing constraints in order to accomplish a specific task. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 9218] New: Revist entry_release handling in slapo-pache, slapo-translucent

by openldap-its＠openldap.org

[Bug 9221] New: Move all replication consumer code into its own overlay

by openldap-its＠openldap.org

https://bugs.openldap.org/show_bug.cgi?id=9221 Bug ID: 9221 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. -- You are receiving this mail because: You are on the CC list for the bug.
