(ITS#7793) mdb_cursor_put(,,,MDB_CURRENT) should ignore key
by h.b.furuseth＠usit.uio.no 27 Jan '14

Full_Name: Hallvard B Furuseth Version: LMDB_0.9.11 OS: Linux x86_64 URL: ftp://ftp.openldap.org/incoming/Hallvard-Furuseth-140128.c Submission from: (NULL) (81.191.45.35) Submitted by: hallvard The doc for mdb_cursor_put:MDB_CURRENT says "The key parameter is ignored". However: - key==NULL gives EINVAL after a thinko in the assert cleanup. 5bda3565a9bfaa6cd54053faeafcc06da15bc00c moved assert(key) from mdb_cursor_set() to the wrong place in the one relevant caller. - A huge key.mv_size triggers mdb_page_spill(). - If data.mv_size==0, the record's key instead of data is modified (so you can modify e.g. key:"foo" to key:"bar"). I expect the test should be (mc->mc_flags & C_SUB). Changing that has a side effect on a non-MDB_CURRENT case: With a cmp function like strncasecmp, changing "KEY" to "key" currently works with if old datasize = new datasize = 0. After this it won't, as with non-empty data of the same size. Test program enclosed.

(ITS#7792) slapd problems - ldap_result: Can't contact LDAP server (-1) result.c:813

Full_Name: Warron French Version: 2.4.38 LTB Project OS: CentOS-6.5 URL: Submission from: (NULL) (130.221.145.5) LTB-Project.org or OpenLDAP.org developers, please help: I am running CentOS-6.5 (on all machines in my little lab) and attempting to setup an LDAP server for user-account authentication, which requires TLS. My CentOS-6.5 machines are all running kernel 2.6.32-431.3.1.el6.x86_64. Also, the version of OpenLDAP I am running based on a suggestion from a user is LTB-Project.org's OpenLDAP-2.4.38, because the version that came natively available with CentOS-6.5's repos was a very old 2.4.23. I am writing a document in order to successfully repeat the build/configuration steps from my lab and lessons learned into a production system. The following is where I am... I am still having problems with adding (via .ldif file) the following LDIF file contents of /tmp/LDAP-CONFIG-TLS.ldif: dn: cn=config changetype: modify add: olcTLSCipherSuite olcTLSCipherSuite: TLSv1+RSA:\!EXP:\!MD5:\!NULL (<- not sure if that argument is valid for that CipherSuite selection either) I use the following ldapmodify command: ldapmodify -x -D "cn=admin,cn=config" -W -f /tmp/LDAP-CONFIG-TLS.ldif Because I have debugging turned up (to -d 32768), the results now look like: modifying entry "cn=config" 52e68423 connection_input: conn=1000 deferring operation: binding slapd: result.c:813: slap_send_ldap_result: Assertion `!((rs->sr_err)<0)' failed. ldap_result: Can't contact LDAP server (-1) I saw a thread on openldap.org on the following link, http://www.openldap.org/lists/openldap-bugs/201308/msg00066.html , that has the exact same error. I can see that Howard Chu from Symas fixed the problem for Symas, did LTB Project fix this problem? I cannot find any threads via websearch for this issue. My /var/log/openldap.log file does not show anything extra. In fact a tail of the log file doesn't even show any errors really. What do I need to do in order to get my LDAP running with TLS? Thank you for any help, I am losing my sanity.

Hard to tell what's going on without seeing the configuration. I'd disable overlays one by one to check whether one of those causes the seg fault. slapo-rwm is one such candidate. Ciao, Michael.

No, I'm talking about X changing the mapsize when there is no txn, then afterwards doing a write txn so the mapsize gets written. > If Y doesn't start its write txn until after X finishes, then Y will > see the new size. It doesn't, that's the point. Only txn_commit pays attention, and it checks the size which existed in the wrong metapage. Come to think of it, set_mapsize(); env_open(); txn begin/end should do the same. Y will either way not pay attention to the new mapsize. -- Hallvard

The doc says the caller of set_mapsize is required to make sure there are no active transactions when it is called. As such, X failed this requirement, and this sequence of events is explicitly unsupported.

(ITS#7790) config.h filename clash. include path broken.

Full_Name: Mark Version: 2.4.35 OS: Solaris 11 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (203.63.89.15) openldap-2.4.35/servers/slapd/back-ldif root# cc -I/usr/local/include -I../../../include -I../../../include -I.. -I./.. -I/usr/local/include -c ldif.c -o ldif.o "ldif.c", line 166: warning: no explicit type given "ldif.c", line 166: syntax error before or at: ldifcfg This happens because there is a /usr/local/include/config.h from libstdc++ which is included before openldap-2.4.35/servers/slapd/config.h, according to the -I include path order. The Makefile sets CFLAGS to "AC_CFLAGS DEFS". DEFS includes XINCPATH which should precede AC_CFLAGS, not succeed it. Either the order needs to be fixed, or more usefully config.h renamed to slapd_config.h To have configure work correctly, CPPFLAGS needs to be set to "-I/usr/local/include" otherwise /usr/local/include isn't searched for db.h, it picks up /usr/include/db.h which is not the one it needs to link against. + print -r -- 'configure:20296: checking for Berkeley DB major version in db.h' [...] 1> conftest.c + /bin/ggrep -E __db_version + eval '$CPP $CPPFLAGS conftest.c' + cc -E conftest.c + set X __db_version 5 none none + ol_cv_bdb_major=5 You can see it's only using CPP and CPPFLAGS in the eval command. Not CFLAGS which has the path for the correct db.h to use. To fix that, CPPFLAGS also needs to point to /usr/local/include. I'm using these fixes to move past both problems and get a properly working build: ./configure --prefix=/usr/local \ --with-cyrus-sasl \ --enable-bdb=yes \ --enable-spasswd=yes \ --enable-modules \ --enable-wrappers \ --enable-shared \ --with-tls=openssl \ ol_cv_berkeley_db_version=4.8.30 mv servers/slapd/config.h servers/slapd/slapd_config.h perl -pe 's#config.h#slapd_config.h#' -i servers/slapd/*.c perl -pe 's#"config.h"#"slapd_config.h"#' -i servers/slapd/*/*.c gmake depend gmake

(ITS#7789) Unreliable mdb_env_set_mapsize()

Full_Name: Hallvard B Furuseth Version: LMDB 0.9.11 OS: Linux x86_64 URL: Submission from: (NULL) (129.240.6.254) Submitted by: hallvard Mapsize changes do not work as described, do not reliably store the mapsize in the map, and it's hard to see how it is supposed to work. E.g.: - Open an environment twice, in processes X and Y. - X grows the map and writes (commits) something to the DB. That MDB_meta gets the new mapsize. - Y writes to the DB. It does not get MDB_MAP_RESIZED like the doc says, nor does it carry forward X's MDB_meta.mm_mapsize change. - Process Z opens the environment without doing set_mapsize(), and gets the original mapsize from the MDB_meta written by Y. For that matter, from reading the doc I'd expect a mapsize change to commit a txn with the new mapsize. There's no mention that the change (and the MDB_MAP_RESIZED) will wait for something to be committed. mdb_txn_commit() writes nothing if the txn didn't change anything. It needs to notice that there is a mapsize change to write. The doc talks about shrinking the map, but reduced mapsizes are not written to the datafile. Only increases are written. All in all, it looks to me like _changing_ the mapsize should be an operation on a write transaction or invoke a write transaction, while setting the size or catching up with a mapsize change can be an environment operation. That way it would be possible to make sense of it. A txn can do it when it has no cursors and no dirty WRITEMAP pages (or WRITEMAP could spill all pages first). BTW, I don't see the point of conditionally avoiding to write the mapsize in mdb_env_write_meta() when full page gets written to disk anyway - as long as txn_begin() stashes the mapsize from the original meta so it knows what to write. (It need not obey the mapsize at that point, but it must carry a change forward.)
