I do have a patch+Perl script which wraps all operation(op, rs) calls, but it doesn't know which ops are "internal". I want it for the SlapReply cleanup (ITS#6758). The only way to make a hunt for dirty SlapReplies feasible. I suggested it when I was doing the cleanup, but IIRC nobody replied - except there were related complaints that my cleanup was too invasive. http://www.openldap.org/lists/openldap-devel/201101/msg00039.html http://folk.uio.no/hbf/OpenLDAP/wrap_slap_ops.txt Anyway, here's me trying agin again:-) -- Hallvard

A definitive and simple solution, although invasive, would be to: - add a o_internal flag to the Operation structure - add a macro BE_INTERNAL(op, rs, op_type) like #define BE_INTERNAL(op, rs, op_type, rcp) \ { int save_o_internal = op->o_internal; op->o_internal = 1; *rcp = (&op->o_bd->bi_info->bi_op_bind)[op_type]( op, rs ); op->o_internal = save_o_internal; } fix all calls to internal operations (brrr....) p.

(ITS#7251) MDB shared mutexes ambiguous on Apple/Windows
by hyc＠OpenLDAP.org 18 Apr '12

18 Apr '12

Full_Name: Howard Chu Version: HEAD/RE24 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (109.151.244.127) Submitted by: hyc Currently since MacOSX and Windows don't support process-shared mutexes residing in shared memory, MDB uses global named semaphores instead on these platforms. The semaphore name is derived from a hash of the pathname of the lock file. This approach was quick and dirty and is prone to failure if relative paths and absolute paths are mixed, or if a file can be accessed thru multiple paths (e.g. symlinks, loopback mounts, whatever). Instead of the pathname, a unique file identifier of the lock file should be used. For MacOSX we can obtain (device,inode) using fstat(). For Windows we can obtain (dwVolumeSerialNumber,nFileIndexLow,nFileIndexHigh) using GetFileInformationByHandle().

Hm, we've run into this similar problem before with syncprov and introduced op->o_dont_replicate. As a general rule, accesslog is meant to log user operations, not internal operations. Currently accesslog checks (op->o_dont_replicate && op->orm_no_opattrs) to skip logging of write ops. I guess we need a more general flag instead. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Thanks, p. > > http://www.stroeder.com/temp/openldap-testbed-its7239.tar.bz2 Thanks. The explanation is always simple, after one finds it. The DN of accesslog entries is generated using the reqStart AVA. When logops all and internal operations take place, multiple entries are generated with the same reqStart AVA. So an internal search which is logged because of some overlay eats up the DN of the modrdn, and be_add() called by slapo-accesslog(5) fails because the entry already exists. Although logging internal entries could be of some use, I see two solutions: - modify the value of reqStart (e.g. instead of using o_tincr for the fractional part of the timestamp, we could use an incremental counter initialized with o_tincr and incremented at each logging within the same operation. The counter could be stored somewhere in the operation structure (e.g. in o_extra) - prevent logging of internal ops; again, this could be achieved by setting a dedicated o_internal_op field in the Operation structure. Since this modification could be intrusive, I'd like to gather some comments before proceeding with a fix. p.

You're clearly missing the point between escaping in shell and in C code. However this is a user error, not an (Open)LDAP bug, so I suggest you direct your question to openldap-technical(a)openldap.org; this ITS will be closed. p. -- Pierangelo Masarati Associate Professor Dipartimento di Ingegneria Aerospaziale Politecnico di Milano

(ITS#7250) Issue with search filter escape sequanced
by malleswari.nandi＠gmail.com 18 Apr '12

Full_Name: Malleswari Nandireddy Version: 2.4.23 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (206.126.170.20) In our code we are using ldap_add_ext_s and ldap_search_ext_s , to add an entry to LDAP and to search and entry in the LDAP. If the enter added is "00*#116cr36_1R1T1S1P1Q1" , then we we try to search using ldap_search_ext_s , it is not returning any records. But when I try to search using ldapsearch , after replacing escape charecter "*" in the string with "\2a" it is returning records. ./ldapsearch -h 10.29.6.33:12660 -x -b 'dc=CVGLDAP,dc=com' 'ets=1:00\2a#116cr36_1R1T1S1P1Q1' We have tried passing 'ets=1:00\2a#116cr36_1R1T1S1P1Q1' to ldap_search_ext_s() , but it is not returning any records. Please help me searching records in LDAP using ldap_search_ext_s() if the filter has escape charecters like "*,(,)....).
