(ITS#8159) Missing parameter in the Configuration man page
by elecharny＠apache.org 01 Jun '15

01 Jun '15

Full_Name: Emmanuel Lecharny Version: 2.4.40 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (212.195.127.200) There is a missing parameter description in the slapd-config man page, on the olcSizeLimit parameter. The doc says : "The syntax size.prtotal={<integer>|unlimited|disabled}..." when the code is also checking for an 'hard' value : } else if ( STRSTART( arg, "prtotal=" ) ) { arg += STRLENOF( "prtotal=" ); ... } else if ( strcasecmp( arg, "hard" ) == 0 ) { limit->lms_s_pr_total = 0;

(ITS#8158) cldap broken for aix and solaris
by goran.hammarback＠foxt.com 29 May '15

29 May '15

Full_Name: G.ran Hammarb.ck Version: 2.4.40 OS: Solaris 11, aix 7.1 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (192.71.43.2) In the routine libraries/liblber/sockbuf.s:sb_dgram_write(), the last argument to the sendto() call is sizeof( struct sockaddr_storage ). While this works on Linux, on Solaris 11 and AIX 7.1 (and likely other versions of these OSes) the call returns EINVAL. This causes attempts to use connectionless ldap to fail. Here is a suggestion to a patch that has been tested on Solaris 11, AIX 7.1 and RedHat 6: *** libraries/liblber/sockbuf.c..org 2015-05-27 09:55:14.001639041 +0200 --- libraries/liblber/sockbuf.c

(ITS#8157) txn can be useless after mdb_txn_renew()
by h.b.furuseth＠usit.uio.no 27 May '15

27 May '15

Full_Name: Hallvard B Furuseth Version: LMDB 0.9.14 OS: URL: Submission from: (NULL) (81.191.45.5) Submitted by: hallvard mdb_txn_renew() may initialize txn halfway and then fail. After that, it refuses to work even when it should have succeeded, since the txn looks active (mt_dbxs != NULL). Fixing.

Sorry, I should I said there's no need to recommend changing MDB_MAXKEYSIZE as anything else than 0, except if you need to make sure old liblmdb versions can use the database. I don't want to restart the discussion about which errors to catch yet again.

Its doc says: "Keys and MDB_DUPSORT data items must fit on a node in a regular page." But the doc should clarify that MDB_MAXKEYSIZE can be set big enough to break lmdb. Or mdb_env_open() can fail if the computed me_maxkey would be smaller. Or compute a safe MIN_PAGESIZE from MDB_MAXKEYSIZE and use that, and then fail if the page size would be unsupported. (MIN_PAGESIZE can be computed at compile time, with some ugly macros.) lmdb sets the max safe maxkeysize if you define MDB_MAXKEYSIZE=0. Some time ago, that was 1/3 of the size you could reasonably use (to allow 1 key + sub-page with 2 dupsort values), so it could make sense to define MDB_MAXKEYSIZE above the safe max. Today lmdb uses a sub-DB at once if a sub-page would be too small, though. So I don't see much need to support maxkeysize > safe max.

(ITS#8155) add support for cacertdir with gnutls
by ryan＠openldap.org 26 May '15

26 May '15

Full_Name: Ryan Tandy Version: OS: URL: Submission from: (NULL) (142.31.146.2) Submitted by: ryan GnuTLS recently (3.3.6) finally added an API for adding a directory of CA files: http://gnutls.org/manual/html_node/Core-TLS-API.html#gnutls_005fcertificate… https://www.happyassassin.net/2015/01/12/a-note-about-ssltls-trusted-certif… Haven't actually tried it yet, but I think it should allow us to implement cacertdir. Just filing this for tracking right now, patch to come later.

(ITS#8154) sizeLimit/timeLimit are described as Multi-value in slapd-config man page
by elecharny＠apache.org 26 May '15

26 May '15

Full_Name: Emmanuel Lecharny Version: 2.4.40 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (109.190.108.22) The slapd-config man page says that we can store the sizeLimit and timeLimit values as multiple values, when they are single value attributes (at least they should be...) : olcTimeLimit: time[.{soft|hard}]=<integer> [...] Specify the maximum number of seconds (in real time) slapd will spend answering a search request. The default time limit is 3600. Use unlimited to specify no limits. The second format allows a fine grain setting of the time limits. Extra args can be added ***in the same value or as additional values***. See olcLimits for an explanation of the different flags.
