If it was such a big problem, why did you not report it when you first encountered it in 2.4.26, which was released over 4 years ago? You waited this long, clearly it's not that high a priority. That makes it even less of a priority for an open source project comprised of volunteers who have their own interests to pursue. Your repeating how big a problem you perceive it to be only comes across as whining, which makes folks even less interested in helping. > slapd of backend ldap crashes 4-5 times per day.

(ITS#8200) Potential use of freed data after mdb_midl_shrink()
by h.b.furuseth＠usit.uio.no 14 Jul '15

14 Jul '15

Full_Name: Hallvard B Furuseth Version: LMDB_0.9.15 OS: URL: Submission from: (NULL) (81.191.45.5) Submitted by: hallvard This code is wrong if the realloc in mdb_midl_shrink fails: if (mdb_midl_shrink(&txn->mt_free_pgs)) env->me_free_pgs = txn->mt_free_pgs; env->me_free_pgs is left pointing as an old, freed IDL. (Freed when mt_free_pgs was originally grown.) It should be: mdb_midl_shrink(&txn->mt_free_pgs); env->me_free_pgs = txn->mt_free_pgs; So mdb_midl_shrink() can return void.

(ITS#8199) Crash when modifying the first olcAttributeTypes element in olcSchemaConfig objectClass

Full_Name: Luca BRUNO Version: 2.4.40 OS: Debian URL: Submission from: (NULL) (217.110.53.72) Hi, slapd 2.4.40 realiably crashes when modifying the 0th olcAttributeTypes element in a olcSchemaConfig object.

PRNG from ITS#7027 (shuffling DNS SRV records) is poorly seeded
by Sergio.Gelato＠astro.su.se 12 Jul '15

12 Jul '15

Full_Name: Sergio Gelato Version: 2.4.40 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (85.225.123.131) As part of ITS#7027, a simple PRNG was added to libraries/libldap/dnssrv.c in order to implement shuffling of SRV RRs as per RFC2782. I see two shortcomings with the way this generator is being seeded. (1) The seed is a very slowly varying function of time: (float)time(NULL) / (2**32-1). The mantissa of an IEEE754 float has 24 bits, so one only gets a new seed every 2**7 seconds with the current seeding method. (2) At any given time, all clients areikikely to use the same seed and therefore pick the same SRV record. This means the load on individual servers will fluctuate a lot more than if the clients picked records in an uncorrelated fashion. To fix (1) I think we need to hash the seed so that it is much more sensitive to the least significant bit of the current time value. (2) can be addressed by mixing in some value that varies from client to client; maybe the 16-bit DNS query ID is most readily available (as the first two bytes of the reply buffer; I hope all implementations of res_query() return it). Come to think of it, shifting the query ID up by 15 bits and XORing with the current time might be good enough.

(ITS#8195) Regression: wrong conversion specifier for "port" in "ldap_domain2hostlist"
by Sergio.Gelato＠astro.su.se 11 Jul '15

Full_Name: Sergio Gelato Version: 2.4.40 OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (85.225.123.131) Commit 5de85b922aaa5bfa6eb53db6000adf01ebdb0736 has undone the fix for ITS#6644. As a consequence, if one has a record _ldap._tcp.example.org IN SRV 0 0 38900 ldap.example.org ldap_domain2hostlist("example.org",&result) returns ldap.example.org:-26636 as the value of the result string.
