(ITS#7943) LMDB fails to process transactions after map resize

Full_Name: Carlo Pires Version: LMDB 0.9.14 OS: Ubuntu Linux 14.04 LTS URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (177.53.184.142) LMDB 0.9.14 is refusing to process new transactions after map resize. The following test case shows the error: /* mtest7.c - memory-mapped database tester/toy */ /* Tests for DB map resize */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <assert.h> #include "lmdb.h" #define E(expr) CHECK((rc = (expr)) == MDB_SUCCESS, #expr) #define EX(err, expr) CHECK((rc = (expr)) == (err), #expr) #define RES(err, expr) ((rc = expr) == (err) || (CHECK(!rc, #expr), 0)) #define CHECK(test, msg) ((test) ? (void)0 : ((void)fprintf(stderr, \ "%s:%d: %s: %s\n", __FILE__, __LINE__, msg, mdb_strerror(rc)), abort())) int main(int argc,char * argv[]) { int rc; MDB_env *env; MDB_dbi dbi; MDB_val key, data; MDB_txn *txn; MDB_envinfo minfo; char kval[32]; char* sval = calloc(1, 8*1024*1024); assert(sval); // create database E(mdb_env_create(&env)); E(mdb_env_set_mapsize(env, 10*1024*1024)); E(mdb_env_set_maxdbs(env, 0)); E(mdb_env_open(env, "./testdb", MDB_NORDAHEAD|MDB_NOLOCK|MDB_NOSYNC, 0664)); // starts dbi E(mdb_txn_begin(env, NULL, 0, &txn)); E(mdb_open(txn, NULL, MDB_CREATE, &dbi)); E(mdb_txn_commit(txn)); // check database mapsize E(mdb_env_info(env, &minfo)); printf("map size is %ldMB\n%, C minfo.me_mapsize/1048576); // try to insert data E(mdb_txn_begin(env, NULL, 0, &txn)); key.mv_size = sizeof(kval); key.mv_data = &kval; data.mv_size = 8*1024*1024; data.mv_data = sval; sprintf(kval, "0"); E(mdb_put(txn, dbi, %kekey, &data, 0)); sprintf(kval, "1"); EX(MDB_MAP_FULL, mdb_put(txn, dbi, &key, &data, 0)); // abort transaction and increase map size mdb_txn_abort(txn); mdb_env_set_mapsize(env, 20*1024*1024); // check database mapsize E(mdb_env_info(env, &minfo)); printf("new map size is %ldMB\n", minfo.me_mapsize/1048576); // try to insert data again E(mdb_txn_begin(env, NULL, 0, &txn)); sprintf(kval, "0"); E(mdb_put(txn, dbi, &key, &data, 0)); sprintf(kval, "1"); E(mdb_put(txn, dbi, &key, &data, 0)); E(mdb_txn_commit(txn)); mdb_env_close(env); free(sval); return 0; } The code worked fine until LMDB 0.9.13.

(ITS#7942) memory leak in control parsing
by hyc＠openldap.org 17 Sep '14

17 Sep '14

Full_Name: Howard Chu Version: 2.4 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (8.25.222.90) Submitted by: hyc A number of controls allocate additional structures in their parsing, stored in the op->o_controls[] array. Nothing cleans these up at the end of the operation. Usually these don't leak because they're allocated on the thread slab, but if the incoming request is large enough it can force them into regular malloc. Fix coming shortly.

Re: (ITS#6035) slapd requires restart after modifying olcAuthzRegexp

Hi, Following up from <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=761407#23>: This limitation seems to still exist (tried RE24 and master). Until it can be fixed, please document it clearly in slapd-config.5 (and maybe the admin guide too), as well as any related attrs if they also require a restart (olcAuthzPolicy?). It's surprising behaviour, since almost every other attribute does support online configuration. Proposed patch follows. thanks, Ryan diff --git a/doc/man/man5/slapd-config.5 b/doc/man/man5/slapd-config.5 index c5bf06f..7c39369 100644 --- a/doc/man/man5/slapd-config.5 +++ b/doc/man/man5/slapd-config.5 @@ -409,6 +409,10 @@ values can be specified to allow for multiple matching and replacement patterns.

Even with -M, it appears impossible to find a specific glued entry, which is problematic when attempting to find if it indeed exists or not outside of a slapcat, or trying to parse (in this case) the 306 broken glued entries that exist in the DB. It would be useful to be able (with -M) to actually search for and find the specific entry so that the account management client can then proceed accordingly. Right now, a search for the specific entry results in error code 32, so then the account management software attempts to create it, which results in error code 68. The software then has no way to find the entry and decide if it needs modification or deletion. OTOH, it is entirely the clients fault for providing bad input, so I'm not sure how hard we should chase it. :P --Quanah -- Quanah Gibson-Mount Server Architect Zimbra, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration

(ITS#7940) Glue entry creation creates entries that cannot be found via ldapsearch filters
by quanah＠openldap.org 16 Sep '14

16 Sep '14

Full_Name: Quanah Gibson-Mount Version: 2.4.39 OS: Linux 3.11 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (75.111.58.125) Found this at a customer site. They loaded an LDIF file that had the child of an entry, but not the entry itself. slapadd then created a glue entry to account for this, however there some significant problems with this process a) The glue entry is not syntactically correct. There is no RDN value. b) It is impossible to use a filter with ldapsearch to find the entry. It appears the objectClass index is utterly broken. Example entry, and the child that created it: dn: uid=abcd,ou=people,dc=xxxx,dc=com,dc=uy entryUUID: a326899a-ad0e-1033-8edf-d9cf7a32cf04 creatorsName: cn=config createTimestamp: 20140731145640Z entryCSN: 20140731145640.037371Z#000000#002#000000 modifiersName: cn=config%momodifyTimestamp: 20140731145640Z objectClass: top objectClass: glue structuralObjectClass: glue dn: zimbraDataSourceName=Adinet,uid=abcd,ou=people,dc=xxxx,dc=com,dc=uy objectClass: zimbraDataSource objectClass: zimbraImapDataSource .... As we can see, the glue entry has no RDN attribute at all. It is also impossible to find this entry via ldapsearch; ldapsearch -x -LLL -D $zimbra_ldap_userdn -w $zimbra_ldap_password -H $ldap_url -b "ou=people,dc=xxxx,dc=com,dc=uy" uid=abcd [zimbra@ldap01 ~]$ [zimbra@ldap01 ~]$ ldapsearch -x -LLL -D $zimbra_ldap_userdn -w $zimbra_ldap_password -H $ldap_url -b "ou=people,dc=xxxx,dc=com,dc=uy" "(objectClass=glue)" 1.1 [zimbra@ldap01 ~]$
