[Bug 9244] New: API calls blocking after async connect

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 9513] New: Enhanced debug output
by openldap-its＠openldap.org 13 Feb '26

13 Feb '26

https://bugs.openldap.org/show_bug.cgi?id=9513 Issue ID: 9513 Summary: Enhanced debug output Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: enhancement Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- While debugging ITS#9479 I needed more information on which threads were doing what actions. Also, when looking for delays/hangs/race conditions, the 1-second granularity of the debug msg timestamp was inadequate. And also, some of the debug output for the Search operation was being done in separate Debug calls for a single line of output. This gets jumbled up pretty badly if other threads are printing output as well. New patch set will extend the debug timestamp to have fractional seconds too; it will use clock_gettime for nanosecond resolution if available, otherwise use gettimeofday for microsecond resolution. Also tweak the Search debug output to only use one Debug invocation per line of output. This is MR!279. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9796] New: Deprecate GnuTLS support

https://bugs.openldap.org/show_bug.cgi?id=9796 Issue ID: 9796 Summary: Deprecate GnuTLS support Product: OpenLDAP Version: 2.6.1 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Support for GnuTLS was added specifically for the Debian (and thus Ubuntu) due to the license objections at the time that the Debian project had for the OpenSSL license. Since that time, Debian has reclassified OpenSSL as a core library and the OpenSSL project has resolved the original complaint by licensing OpenSSL 3 and later under the Apache License v2. Thus there is no longer a reason to maintain support for GnuTLS and given the long standing concerns over the security and quality of the GnuTLS bridge in addition to the extra cost of maintaining that code, it should be marked as deprecated and removed in a future release. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9577] New: slapd -V should be deprecated
by openldap-its＠openldap.org 16 Dec '25

https://bugs.openldap.org/show_bug.cgi?id=9577 Issue ID: 9577 Summary: slapd -V should be deprecated Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: smckinney(a)symas.com Target Milestone: --- Sometimes a user's (present one included) ignorance gets them in trouble unnecessarily. The -V option is an example... Normally, when one wants to determine the version of a process, they use -V, or perhaps -v. With slapd, the daemon actually continues to run, which can have negative consequences. The doc clearly states that -VV is probably what the user wants, but is counter-intutive. Who RTFM's before checking the version? -V print version info (-VV exit afterwards, -VVV print info about static overlays and backends) I propose we eliminate the option to allow slapd to continue running after displaying the version. Perhaps we eliminate the -V option entirely, or just make it work the same as -VV. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9640] New: ACL privilege for MOD_INCREMENT

https://bugs.openldap.org/show_bug.cgi?id=9640 Issue ID: 9640 Summary: ACL privilege for MOD_INCREMENT Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: michael(a)stroeder.com Target Milestone: --- I'm using LDAP write operations with MOD_INCREMENT with pre-read-control for uidNumber/gidNumber generation. I'd like to limit write access to an Integer attribute "nextID" to MOD_INCREMENT, ideally even restricting the de-/increment value. (Uniqueness is achieved with slapo-unique anyway but still I'd like to avoid users messing with this attribute). IMHO the ideal solution would be a new privilege "i". Example for limiting write access to increment by one and grant read access for using read control: access to attrs=nextID val=1 by group=... =ri Example for decrementing by two without read: access to attrs=nextID val=-2 by group=... =i -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9584] New: cn=config replication ops/refresh should pause server

https://bugs.openldap.org/show_bug.cgi?id=9584 Issue ID: 9584 Summary: cn=config replication ops/refresh should pause server 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: --- Looking into this crash: https://git.openldap.org/openldap/openldap/-/jobs/7286 The thread in question is running a plain syncrepl refresh while another thread seems to have done the same. This thread fetched the entryUUID attribute of the 'cn=config' entry as 'a' and in the meantime, that entry has been rewritten, with 'a' presumably cleaned up and returned to the pool, so addressing a->a_nvals[0] is a NULL-dereference now. This might or might not be related to the fix in ITS#8102. -- You are receiving this mail because: You are on the CC list for the issue.
