Fix Description: Created a new "monitoring" thread that checks all the replicas RUV's to see if the rid was cleaned. Once they are cleaned, we automatically release the RID for reuse.

An intruder can brute force guess the password all day long until they succeed, especailly if the DS is publicly available. Fix Description: Created a new plugin, type "internalpreoperation" and an internal preop bind function. You can configure the plugin with some basic access control: rootdn-open-time: 0800 rootdn-close-time: 1700 rootdn-days-allowed: Mon, Tue, Wed, Thu, Fri rootdn-allow-host: *.redhat.com rootdn-allow-host: *.fedora.com rootdn-deny-host: dangerous.boracle.com rootdn-allow-ip: 127.0.0.1 rootdn-allow-ip: 2000:db8:de30::11 rootdn-deny-ip: 192.168.1.* As with our other ACL code, deny's

Branch: master Fix Description: The problem was that because usn was creating a tombstone, it was also setting the OP_FLAG_TOMBSTONE flag in the operation, which was causing the operation to think it was deleting a tombstone. The fix is to not set this flag, and instead have operations that delete tombstones to set that flag explicitly when creating the delete op request. In addition, the CSN for delete ops was not being logged - the usn bepostop was deleting it, even when replication was being used. Previously the csn was needed as a "trigger" to tell the ldbm_back_delete code to create a tombstone rather than deleting the entry outright. Instead, use the slapi_operation_get_replica_attr (pb, operation, "nsds5ReplicaTombstonePurgeInterval, &create_tombstone_entry) to determine whether or not to create a tombstone entry. Both replication and usn configure this, so if using one or both of those, tombstones will be created, otherwise, not.

Branch: master Fix Description: 1) Fix handling of DB_LOCK_DEADLOCK conditions. When a database operation returns DB_LOCK_DEADLOCK, all cursors must be closed, and the transaction aborted and retried. If not in a transaction, the operation may be retried immediately. This fix adds this logic to many places in the db code where it was lacking. 2) Fix resetting of the data when an operation has to be retried. When a transaction has to be retried, we must reset the data to the same state it was before any of the operations in the transaction were attempted. This includes the entry cache state, which was lacking in a number of ways. One major problem with resetting the cache is that cache_add_tentative adds an entry to the dncache, but not the idcache, in order to reserve a space in the cache, and to prevent other entries with the same DN from being added while the operation is in progress. There was no good way to remove this entry. In the case of modrdn, removing the tentative entry would also remove the real entry since they share the same entryid. This fix also makes sure that in error conditions, temporary entries are removed from the cache and properly freed, and real entries are "rolled back" into the cache. 3) Added a transaction stress thread. This thread can simulate various types of read and write locking that can cause conflicts and trigger regular database operations to return DB_LOCK_DEADLOCK. The usual culprit is read locks which are held on pages that are searched outside of a transaction. The stress thread can lock, via read cursors, all of the pages in all of the indexes in the database, and hold these pages for some set period of time, then loop and do it again. 4) It is quite easy to get the database in a deadlock situation, where a update operation is waiting for a read lock to be released in order to write to a page, while a search operation is waiting for a write lock to be released in order to read lock the page. If we are going to allow concurrent searches during update operations, without making search requests transacted, we need to have some way to detect these deadlocks. The fastest way to do it is to use the DB_TXN_NOWAIT flag when starting transactions. This tells bdb to return immediately with a DB_LOCK_DEADLOCK if the transaction cannot proceed due to a locked page (e.g. a search request has read locked a page). Alternately, we could have transactions wait for some specified period of time, but if we think that this type of thread contention is going to be rare, it makes sense to return immediately, if our deadlock handling is fast and robust. 5) Fixed some memory leaks 6) The txn_test thread needs to know when the backend databases are available - had to add a backend flag BE_STATE_STOPPING so that the txn_thread knows when the databases are available 7) If the op was retried RETRY_TIMES times, return LDAP_BUSY instead of OPERATIONS_ERROR - the problem really is that the server is busy with other transactions, and the operation could go through if the client were to retry. 8) Renaming an entry without changing the dn e.g. changing the case does not cache the entry, so handle that 9) Added a delay when a deadlock is encountered in modrdn - same as the other add/mod/del cases Platforms tested: RHEL6 x86_64, Fedora 17 Flag Day: yes Doc impact: yes (cherry picked from commit 48b8ace54583662306c75f22f2f243fc274251af) diff --git a/ldap/servers/plugins/replication/repl5_plugins.c b/ldap/servers/plugins/replication/repl5_plugins.c index a768edb..2b4d0c9 100644 --- a/ldap/servers/plugins/replication/repl5_plugins.c +++ b/ldap/servers/plugins/replication/repl5_plugins.c @@ -1007,6 +1007,11 @@ write_changelog_and_ruv (Slapi_PBlock *pb) return 0;

Branch: master Fix Description: The problem was that because usn was creating a tombstone, it was also setting the OP_FLAG_TOMBSTONE flag in the operation, which was causing the operation to think it was deleting a tombstone. The fix is to not set this flag, and instead have operations that delete tombstones to set that flag explicitly when creating the delete op request. In addition, the CSN for delete ops was not being logged - the usn bepostop was deleting it, even when replication was being used. Previously the csn was needed as a "trigger" to tell the ldbm_back_delete code to create a tombstone rather than deleting the entry outright. Instead, use the slapi_operation_get_replica_attr (pb, operation, "nsds5ReplicaTombstonePurgeInterval, &create_tombstone_entry) to determine whether or not to create a tombstone entry. Both replication and usn configure this, so if using one or both of those, tombstones will be created, otherwise, not.

Branch: master Fix Description: 1) Fix handling of DB_LOCK_DEADLOCK conditions. When a database operation returns DB_LOCK_DEADLOCK, all cursors must be closed, and the transaction aborted and retried. If not in a transaction, the operation may be retried immediately. This fix adds this logic to many places in the db code where it was lacking. 2) Fix resetting of the data when an operation has to be retried. When a transaction has to be retried, we must reset the data to the same state it was before any of the operations in the transaction were attempted. This includes the entry cache state, which was lacking in a number of ways. One major problem with resetting the cache is that cache_add_tentative adds an entry to the dncache, but not the idcache, in order to reserve a space in the cache, and to prevent other entries with the same DN from being added while the operation is in progress. There was no good way to remove this entry. In the case of modrdn, removing the tentative entry would also remove the real entry since they share the same entryid. This fix also makes sure that in error conditions, temporary entries are removed from the cache and properly freed, and real entries are "rolled back" into the cache. 3) Added a transaction stress thread. This thread can simulate various types of read and write locking that can cause conflicts and trigger regular database operations to return DB_LOCK_DEADLOCK. The usual culprit is read locks which are held on pages that are searched outside of a transaction. The stress thread can lock, via read cursors, all of the pages in all of the indexes in the database, and hold these pages for some set period of time, then loop and do it again. 4) It is quite easy to get the database in a deadlock situation, where a update operation is waiting for a read lock to be released in order to write to a page, while a search operation is waiting for a write lock to be released in order to read lock the page. If we are going to allow concurrent searches during update operations, without making search requests transacted, we need to have some way to detect these deadlocks. The fastest way to do it is to use the DB_TXN_NOWAIT flag when starting transactions. This tells bdb to return immediately with a DB_LOCK_DEADLOCK if the transaction cannot proceed due to a locked page (e.g. a search request has read locked a page). Alternately, we could have transactions wait for some specified period of time, but if we think that this type of thread contention is going to be rare, it makes sense to return immediately, if our deadlock handling is fast and robust. 5) Fixed some memory leaks 6) The txn_test thread needs to know when the backend databases are available - had to add a backend flag BE_STATE_STOPPING so that the txn_thread knows when the databases are available 7) If the op was retried RETRY_TIMES times, return LDAP_BUSY instead of OPERATIONS_ERROR - the problem really is that the server is busy with other transactions, and the operation could go through if the client were to retry. 8) Renaming an entry without changing the dn e.g. changing the case does not cache the entry, so handle that 9) Added a delay when a deadlock is encountered in modrdn - same as the other add/mod/del cases Platforms tested: RHEL6 x86_64, Fedora 17 Flag Day: yes Doc impact: yes diff --git a/ldap/servers/plugins/replication/repl5_plugins.c b/ldap/servers/plugins/replication/repl5_plugins.c index dfbb80e..5ca6d90 100644 --- a/ldap/servers/plugins/replication/repl5_plugins.c +++ b/ldap/servers/plugins/replication/repl5_plugins.c @@ -997,6 +997,11 @@ write_changelog_and_ruv (Slapi_PBlock *pb) return 0;

Branch: 389-ds-base-1.2.10 Fix Description: The usn code called from ldbm_back_delete was adding entryusn and preventryusn to the entry directly in the cache. If another thread was accessing the entry (e.g. an internal search done by referint or memberof, or an external search) at the same time, the server would crash. The fix is to not modify the cached entry directly - instead, modify a copy of the entry, and apply the entryusn set in the copy to the tombstone. Then we don't need to use SLAPI_DELETE_BEPREOP_ENTRY or SLAPI_DELETE_BEPOSTOP_ENTRY at all. We don't need to clean up the postentry - we are not setting entryusn or preventryusn in the real entry - we are setting those values in the tombstone entry - if successful, the values will be added or deleted accordingly - if not successful, the values are thrown away and freed.
