(ITS#6692) LDAP_INAPPROPRIATE_MATCHING not returned when faced with an unsupported extensible match
by doug.leavitt＠oracle.com 02 Nov '10

02 Nov '10

Full_Name: Doug Leavitt Version: HEAD OS: Solaris URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (192.18.43.225) It seems that slapd is returning success if an unsupported extensible match is given. Probably LDAP_INAPPROPRIATE_MATCHING or maybe LDAP_UNAVAILABLE_CRITICAL_EXTENSION chould be returned. Instead. Example: Attempting a search using the MS LDAP_MATCHING_RULE_IN_CHAIN extensible match rule: http://msdn.microsoft.com/en-us/library/aa746475%28VS.85%29.aspx OID: 1.2.840.113556.1.4.194 Should fail since it is currently unsupported by OpenLDAP. Something like: ldapsearch -v -h <server> -D <admin dn> -w <admin pw> -b <base> "memberof:1.2.840.113556.1.4.1941:=cn=ldap_many1,dc=mc,dc=sun,dc=com" Should return error, but instead returns success with 0 matches. I believe that the root of the problem is that in servers/slapd/filter.c: case LDAP_FILTER_EXT: Debug( LDAP_DEBUG_FILTER, "EXTENSIBLE\n", 0, 0, 0 ); err = get_mra( op, ber, &f, text ); if ( err != LDAP_SUCCESS ) { break; >>> err is returned with the value LDAP_INAPPROPRIATE_MATCHING } assert( f.f_mra != NULL ); break; default: (void) ber_scanf( ber, "x" ); /* skip the element */ Debug( LDAP_DEBUG_ANY, "get_filter: unknown filter type=%lu\n", f.f_choice, 0, 0 ); f.f_choice = SLAPD_FILTER_COMPUTED; f.f_result = SLAPD_COMPARE_UNDEFINED; break; } >>> and will return LDAP_SUCCESS with the following: if( err != LDAP_SUCCESS && err != SLAPD_DISCONNECT ) { /* ignore error */ *text = NULL; f.f_choice = SLAPD_FILTER_COMPUTED; f.f_result = SLAPD_COMPARE_UNDEFINED; err = LDAP_SUCCESS; } which will allow the filter to proceed, loosing the error. It seems like the search should fail given an illegal/unsupported extensible filter.

Re: (ITS#6691) error 4 in slapd: segfault with back-sql in debian amd64

Looks like a duplicate of ITS#6657; I have already investigated that bug to no avail. Apparently, a pointer to stack-residing data is erroneously freed. You may be able to find out more info by checking where this happens from the core. I can't take care of this issue right now as I'd need to give it incredibly low priority. p. > Ok, thanks for the answer > > This is the new backtrace: > > Core was generated by `./slapd -d -1'. > Program terminated with signal 11, Segmentation fault. > [New process 1656] > [New process 1570] > [New process 1573] > #0 0x0000000000491ac5 in slap_sl_free (ptr=0xffffffd2028b00d0, > ctx=0x28a3120) > at sl_malloc.c:490 > 490 if ( tmpp[-1] & 1 ) { > (gdb) bt > #0 0x0000000000491ac5 in slap_sl_free (ptr=0xffffffd2028b00d0, > ctx=0x28a3120) > at sl_malloc.c:490 > #1 0x00000000004d562e in backsql_entry_clean (op=0x28a9b10, e=0x42e98a40) > at search.c:2680 > #2 0x00000000004d4e8f in backsql_search (op=0x28a9b10, rs=0x42e99ca0) > at search.c:2517 > #3 0x0000000000429f5c in fe_op_search (op=0x28a9b10, rs=0x42e99ca0) > at search.c:366 > #4 0x00000000004298c7 in do_search (op=0x28a9b10, rs=0x42e99ca0) > at search.c:217 > #5 0x0000000000426952 in connection_operation (ctx=0x42e99df0, > arg_v=0x28a9b10) at connection.c:1109 > #6 0x0000000000426ede in connection_read_thread (ctx=0x42e99df0, > argv=0x9) > at connection.c:1245 > #7 0x000000000050e33b in ldap_int_thread_pool_wrapper (xpool=0x26f6ea0) > at tpool.c:685 > #8 0x00007fddda10cfc7 in start_thread () from /lib/libpthread.so.0 > #9 0x00007fddd9e8264d in clone () from /lib/libc.so.6 > #10 0x0000000000000000 in ??

Re: (ITS#6688) OpenLDAP 2.4.23 doesn't enforce ACLs on back-perl subordinate database
by mark.cave-ayland＠siriusit.co.uk 29 Oct '10

Hi all, An update on this bug report: with a modified slapd.conf and a small patch to the back-perl module, I can use the ACL mask to ensure that the perl search function doesn't get invoked if disallowed by the ACLs. The patch works by creating a "fake" empty entry whose DN is the base of the search, and then passing this entry into access_allowed() using code borrowed from one of the other backends to either deny or allow access. http://pastebin.siriusit.co.uk/perlacl/slapd2.conf http://pastebin.siriusit.co.uk/perlacl/openldap-backperl-acls.patch Is this something that could be considered for inclusion upstream or does it require more work?
