Re: (ITS#4964) consumer with slapo-chain segfaults when using ldappasswd

This is now completely fixed in HEAD; I need to check any issue related to backporting to re23, for quick release. Please test. Thanks for reporting, p. Ing.

(ITS#4973) Inconsistent initialization of internal modifications
by ando＠sys-net.it 19 May '07

19 May '07

Full_Name: Pierangelo Masarati Version: HEAD OS: irrelevant URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (81.72.89.40) Submitted by: ando While fixing slapo-chain(5) handling of passmods, I stumbled into an inconsistent initialization of internal modifications. What happens is that in most cases the Operation structure used for internal operations is either directly the structure passed to the function that performs the internal operation, or a copy of it, something like Operation op2 = *op; The oq_modify.rs_modlist member now contains an orm_no_opattrs field which, if non-zero, inhibits the modification of operational attributes, and thus indirectly breaks replication. I've fixed the occurrence in passwd_extop(), but the code is full of internal modifications that might need care. p.

I've updated and applied a patch I had lying around for this one: Give OperationBuffer struct members instead of using LBER_ALIGNED_BUFFER. -- Regards, Hallvard

I assume you refer to a patch that was submitted along with ITS#4868; that patch is absolutely incorrect and in fact it has been rejected. A consistent fix has been applied to hEAD code. It has never been backported to OpenLDAP 2.3 because nobody fed back about it. If you wish to test HEAD code and report success, I'll be happy to backport it to OpenLDAP 2.3 so that it gets released with the next release. > And by the way I want to store 'userCertificate' attribute type in PostrgreSQL. > > What type of the field in the table should I use?

And I want to know more about this problem, if possible. Please direct software use related questions to the openldap-software mailing list. p. Ing.

(ITS#4972) thr_debug problems
by h.b.furuseth＠usit.uio.no 18 May '07

18 May '07

Full_Name: Hallvard B Furuseth Version: HEAD, RE23 OS: URL: Submission from: (NULL) (129.240.202.105) Submitted by: hallvard $LDAP_THREAD_DEBUG parsing is bogus, code in the inner loop should be outside it. Detached threads can validly exit after ldap_debug_thread_destroy() (fixed in HEAD). Valgrind carries the 'uninialized' state out of debug_already_initialized(). RE23/thr_debug.c has some other problems that are fixed in HEAD, but take a bit more work to fix and test. I'll align it with HEAD if anyone is interested.

Unfortunately the problem has not been completely fixed in the HEAD. With the fix in the head the error message disappears but the contextCSN ins NOT ACTUALLY written to the disk. So at the next slapd startup the ContextCSN is missing. An the servers hav to resynchronize. Below you find the log extract.
