[Bug 9244] New: API calls blocking after async connect
by openldap-its＠openldap.org 07 Aug '26

07 Aug '26

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.

[Issue 9729] New: Allow setting multiprovider before adding syncrepl stanzas

Instead, the only requirement should be that serverID has been explicitly set (hopefully != 0). -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9642] New: Adding a task to runqueue doesn't wake the main thread

https://bugs.openldap.org/show_bug.cgi?id=9642 Issue ID: 9642 Summary: Adding a task to runqueue doesn't wake the main thread Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- If a connection adds a new syncrepl stanza, that is not started until the main thread comes around to doing it. However if that thread is currently stuck in SLAP_EVENT_WAIT() and nothing else happens (like an unbind over the connection that modified the config), the task is never started. This can take a long time. No idea yet how to wake it up with/from ldap_pvt_runqueue_insert() given that sits within libldap and not really something that should be calling slap_wake_listener(). -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10306] New: epoll, kqueue etc. are not used when cross compiling
by openldap-its＠openldap.org 07 Aug '26

07 Aug '26

https://bugs.openldap.org/show_bug.cgi?id=10306 Issue ID: 10306 Summary: epoll, kqueue etc. are not used when cross compiling Product: OpenLDAP Version: 2.6.9 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: build Assignee: bugs(a)openldap.org Reporter: hi(a)alyssa.is Target Milestone: --- OpenLDAP's build system relies on running test programs to see whether epoll or kqueue are available, after checking the headers are available. When cross compiling, test programs can't be run, and even if they could, they wouldn't produce useful results because they'd be testing the build machine. Running test programs like this isn't even a great idea for native builds, because the package is still quite likely to end up running on a different machine than it was built for — think about distro packages. This means that cross-compiled OpenLDAP ends up using select, even though it could almost certainly use epoll or kqueue. The best thing to do for this sort of thing is to check at runtime whether the epoll/kqueue/whatever is available, and fall back if not, but this would probably be hard to implement in OpenLDAP. Other, easier, things that could be done to improve the situation would be: • Assume that epoll/kqueue are available if the headers are. It's very unlikely nowadays that a system with the headers won't actually have the API available. • If the AC_RUN_IFELSE checks are staying, make sure that they're all overridabel with configure flags or at least AC_CACHE_CHECK. There are also uses of AC_RUN_IFELSE for pthreads, which presumably have the same problem. -- You are receiving this mail because: You are on the CC list for the issue.
