[Issue 9037] observing crash in mdb_cursor_put()

https://bugs.openldap.org/show_bug.cgi?id=9037 --- Comment #28 from mdufour(a)audiokinetic.com --- Apologies, in the last message, the provide line of code is indeed 7998, the crash location (and not 8183 as written). It is slightly different from the official mdb.c due to some unrelated local changes earlier in the file. -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=9037 --- Comment #27 from mdufour(a)audiokinetic.com --- We are also seeing rare instances of this crash since we released a version of our product which uses LMDB. Specifically, call stack is: mdb_cursor_put(MDB_cursor * mc, MDB_val * key, MDB_val * data, unsigned int flags) Line 7998 mdb_put(MDB_txn * txn, unsigned int dbi, MDB_val * key, MDB_val * data, unsigned int flags) Line 10107 where line 8183 is nsize = IS_LEAF2(mc->mc_pg[mc->mc_top]) ? key->mv_size : mdb_leaf_size(env, key, rdata); and mc->mc_top == 0 mc->mc_pg[0] == NULL rc == -30798 Although we do not have a reproduction case, we do have a full crash dump with heap of an unoptimized debug build of our application. There is no evidence of stack corruption (in fact, mc->mc_pg[1] is still 0xcccccccccccccccc as per the msvc run-time check initialization). Unfortunately we do not have the matching LMDB file. Anything we can provide to help narrow down the issue? -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10184] New: slapo-translucent

https://bugs.openldap.org/show_bug.cgi?id=10184 Issue ID: 10184 Summary: slapo-translucent Product: OpenLDAP Version: 2.6.3 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: marco.esposito(a)gmail.com Target Milestone: --- I am currently experiencing an issue with an OpenLDAP instance configured with the slapo-translucent overlay. After performing an ldapmodify: # ldapmodify -x -D cn=Manager,dc=example,dc=com -W -H ldap:/// <<EOF dn: uid=user,ou=People,dc=example,dc=com changetype: modify replace: uidNumber uidNumber: 99 EOF LDAP queries requesting only translucent local attributes do not return results unless both the remote and local attributes are included in the filter. Here is an example illustrating the behavior: Query with both remote and local attributes in the filter after ldapmodify (works correctly): # ldapsearch -x -D "cn=Manager,dc=example,dc=com" -W -H ldap:/// -b "ou=People,dc=example,dc=com" "(uid=user)" uid uidNumber # extended LDIF # # LDAPv3 # base <ou=People,dc=example,dc=com> with scope subtree # filter: uid=user # requesting: uid uidNumber # # user, People, example.com dn: uid=user,ou=People,dc=example,dc=com uidNumber: 99 uid: user # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 Query with only local attributes in the filter after ldapmodify (does not return results): # ldapsearch -x -D "cn=Manager,dc=example,dc=com" -W -H ldap:/// -b "ou=People,dc=example,dc=com" "(uid=user)" uidNumber # extended LDIF # # LDAPv3 # base <ou=People,dc=example,dc=com> with scope subtree # filter: uid=user # requesting: uidNumber # # search result search: 2 result: 0 Success # numResponses: 1 While attempting to debug the issue, I believe the problem may be related to the code in lines 928 - 940 of the file overlays/translucent.c: https://git.openldap.org/openldap/openldap/-/blob/master/servers/slapd/over… Specifically, I suspect that the issue may be related to the conditions within the 'if' statement. I have carefully reviewed the slapd instance configuration and overlay settings, but I have not been able to identify the root cause. Any assistance or advice on resolving this issue would be greatly appreciated. Thank you for your time and support.
