[Issue 9504] New: Assertion failure after reconfiguring olcDbIDAssertBind in slapd-ldap

https://bugs.openldap.org/show_bug.cgi?id=9504 Issue ID: 9504 Summary: Assertion failure after reconfiguring olcDbIDAssertBind in slapd-ldap Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: backends Assignee: bugs(a)openldap.org Reporter: tero.saarni(a)est.tech Target Milestone: --- OpenLDAP crashes to following assert error: slapd: bind.c:2657: ldap_back_proxy_authz_ctrl: Assertion `0' failed. The crash can be reproduced by executing following sequence: 1. create proxy with OLC configuration 2. execute modify operation that changes olcDbIDAssertBind (replace or delete&add) but do set mode=legacy as the value 3. execute ldapsearch as user that maps into idassert-bind 4. slapd crashes with the above error message mode=legacy is the default and everything works after initial configuration (1) even without adding mode=legacy into the configuration, but when doing re-configuration using OLC (2) the default value does not seem to get initialized correctly anymore. This causes next LDAP operation (3) to fail after changing the configuration since the server crashes (4). The assert in question is here, in the default branch when "mode" variable is not set at all: https://git.openldap.org/openldap/openldap/-/blob/c9ee2ccd1c8aadaef9db90742… -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9382] New: client tools ldapvc.c tracks criticality but doesn't use it

It would appear the intention was to determine whether or not this control is marked critical and then do something based on that, but there is in fact nothing ever done. This leads to a warning that crit is set but unused. If the criticality of the control doesn't matter, than this variable should be eliminated. If it does matter, then the missing code needs to be added. -- You are receiving this mail because: You are on the CC list for the issue.

We thought it was due to some weird stuff we were doing in the 16.04 version (2.4.42+dfsg-2ubuntu3.8), but we deployed a new LDAP proxy in 20.04 (2.4.49+dfsg-2ubuntu1.2) which appears to have the same issue so I am reporting it and hoping for guidance as we use this proxy for our corporate VPN. Below is the backtrace which was the same from both proxy systems, but this one is from the 20.04 version as that is our current system in use: root@useldap02:~/_usr_sbin_slapd.0.crash# apport-retrace --stdout /var/crash/_usr_sbin_slapd.0.crash --- stack trace --- #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 set = {__val = {0, 140488162916432, 140488307736576, 140487911640016, 140487911640117, 140487911640016, 140487911640016, 140487911640147, 140487911640316, 140487911640016, 140487911640316, 0, 0, 0, 0, 0}} pid = <optimized out> tid = <optimized out> ret = <optimized out> #1 0x00007fc5f3043859 in __GI_abort () at abort.c:79 save_stage = 1 act = {__sigaction_handler = {sa_handler = 0x2, sa_sigaction = 0x2}, sa_mask = {__val = {131, 4, 99, 0, 0, 140488164070405, 0, 21474836480, 140488121483504, 0, 140488164102160, 0, 6703301646461552640, 140488164070405, 140488165695488, 140488164087176}}, sa_flags = -235332728, sa_restorer = 0xbf} sigs = {__val = {32, 0 <repeats 15 times>}} #2 0x00007fc5f3043729 in __assert_fail_base (fmt=0x7fc5f31d9588 "%s%s%s:%u: %s%sAssertion `%s' failed.\n%n", assertion=0x7fc5f1f91953 "!LDAP_BACK_CONN_TAINTED( lc )", file=0x7fc5f1f91b88 "../../../../../servers/slapd/back-ldap/bind.c", line=191, function=<optimized out>) at assert.c:92 str = 0x7fc5c410a280 "@Q\021\344\305\177" total = 4096 #3 0x00007fc5f3054f36 in __GI___assert_fail (assertion=0x7fc5f1f91953 "!LDAP_BACK_CONN_TAINTED( lc )", file=0x7fc5f1f91b88 "../../../../../servers/slapd/back-ldap/bind.c", line=191, function=0x7fc5f1f921a0 "ldap_back_conn_delete") at assert.c:101 No locals. #4 0x00007fc5f1f807c7 in ldap_back_conn_delete () from /usr/lib/ldap/back_ldap-2.4.so.2 No symbol table info available. #5 0x00007fc5f1f814a4 in ??
