[Bug 9244] New: API calls blocking after async connect
by openldap-its＠openldap.org 07 Nov '23

07 Nov '23

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 07 Nov '23

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 9221] New: Move all replication consumer code into its own overlay
by openldap-its＠openldap.org 07 Nov '23

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.

https://bugs.openldap.org/show_bug.cgi?id=9218 Bug ID: 9218 Summary: Revist entry_release handling in slapo-pache, slapo-translucent 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: --- 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 -- You are receiving this mail because: You are on the CC list for the bug.

[Issue 10072] New: Querying for transaction memory use
by openldap-its＠openldap.org 28 Oct '23

https://bugs.openldap.org/show_bug.cgi?id=10072 Issue ID: 10072 Summary: Querying for transaction memory use Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: tagwerk19.openldap(a)innerjoin.org Target Milestone: --- It would be useful to have a way to ask liblmdb how much "dirty memory" a transaction is using, up to that point. The goal is to be able to bundle writes into fewer transactions, making best use of available memory and reducing total disc writes. It is possible for an application to count the number of writes but this has only a loose relation to the *actual* number of dirty pages flagged. The target would be to write data up until the dirty memory gets to a threshold and then commit. I see that there's a: txn->mt_dirty_room and wonder if MDB_IDL_UM_MAX - txn->mt_dirty_room would give a count of that an "aware" application could make use of (an exact count? or maybe a usable and sufficient indication?) The need for this has been sharpened with the use of systemd service files that cap the memory allowed for a process, for example: MemoryHigh=512M If the process reaches this limit and continues to write data, the system uses swap.

[Issue 10085] New: test029 can't pass with SLAPD_USE_SASL is set
by openldap-its＠openldap.org 25 Oct '23

https://bugs.openldap.org/show_bug.cgi?id=10085 Issue ID: 10085 Summary: test029 can't pass with SLAPD_USE_SASL is set Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: test suite Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Running make test with SLAPD_USE_SASL set will fail test029. There is even a comment there that we can't support that functionality as-is when SASL binds are configured. We should probably remove that part of the test or skip it unconditionally for now. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10045] New: back-config operations abandoned while waiting in slap_pause_server() aren't committed to ldif

https://bugs.openldap.org/show_bug.cgi?id=10045 Issue ID: 10045 Summary: back-config operations abandoned while waiting in slap_pause_server() aren't committed to ldif Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- slap_pause_server() can take an unbounded time to process and it is possible the operation is abandoned in the meantime (e.g. the connection is lost and the loss is still noticed at this point). However the processing still goes ahead and passed onto back-ldif - where it is discarded as abandoned already so we can end up with an inconsistent view of our persistent configuration. Checking op->o_abandon again after slap_pause_server() finishes might be enough. -- You are receiving this mail because: You are on the CC list for the issue.
