* Lock around more ulog operationsGreg Hudson2014-02-201-1/+2
| | | | | | | | | | | | | | | Always lock the ulog when accessing it. We can currently get away with some laxness on iprop slaves because they are mostly synchronous, but hierarchical iprop will allow master and slave operations to take place concurrently, requiring more strict locking. Add new functions ulog_get_last and ulog_set_last, which access the ulog header with locking, and use them in kdb5_util and kpropd. Add locking to ulog_replay and ulog_init_header. ulog_lock and ulog_sync_header are no longer used outside of kdb_log.c after these changes, so make them static functions and remove the ulog_ prefix. Add an unlock_ulog function for clarity.
* Factor out ulog serial number status checkGreg Hudson2014-02-201-0/+1
| | | | | | | | | | | | | | | Add a new function ulog_get_sno_status, which checks a serial number and timestamp against the ulog for currency. Use it in kdb5_util dump and in ulog_get_entries. Adjust parse_iprop_header's contract in dump.c to better match the ulog_get_sno_status contract. This change causes some minor behavior differences. kadmind will check for an empty ulog unless the last serial number matches exactly, and will never set lastentry when returning UPDATE_FULL_RESYNC_NEEDED (which was pointless). kdb5_util dump will recognize a dump file as current if it exactly matches the last serial number, even if the ulog is empty; it will be more robust in the presence of non-monotonic clocks; and it will properly lock around the ulog access.
* Add test case for ulog serial number wrappingGreg Hudson2014-01-301-0/+1
| | | | | | | | | Add a unit test program named t_ulog. Make it map a ulog file, set up header state where kdb_last_sno is the last serial number, and then add an empty update. Check that the result is a ulog header with one update at serial number 1. ticket: 7839
* Fix iprop log reinitializationGreg Hudson2013-01-221-0/+1
| | | | | | | | | | | | | | | | If the master iprop log is reinitialized to serial number 0, slaves will need to take a full dump--but after that happens, we need to know whether the slave has taken that full dump, we we don't offering full dumps indefinitely. So, record a timestamp in kdb_last_time when we reinitialize the log header, and compare the slave timestamp to kdb_last_time whenever it has the current serial number, even if it's 0. Test this by performing a propagation with sno 0 in t_iprop.py and detecting whether kpropd gets a second UPDATE_FULL_RESYNC_NEEDED response from kadmind. ticket: 7550 (new)
* Use a single global dump for iprop full syncsNicolas Williams2012-10-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Use a global dump (the default dump file) for full syncs for iprop. When a slave asks for a fullsync we kprop the existing global dump to it if that is good enough, else we dump the DB and send the new global dump. Before this change kadmind would run kdb5_util dump -i... each time a slave asked for a full dump. This was done in a sub-process, thankfully, but it was still a waste of time and storage (e.g., if one has a huge KDB). Also, long dump times might cause a slave to give up (the timeout for this is now configurable). But since iprop dumps bear a serial number and timestamp and since slaves will resync from that point forward, it doesn't matter if the dump we send a slave is fresh as long as it is fresh enough (i.e., that its sno and timestamp are in the ulog). Also: - Rename dumps into place instead of unlink, create, write (but we still keep the dump ok files as lock files and as a method of signaling to kprop that the dump is complete). ticket: 7371
* Policy extensions + new policy: allowed ks typesNicolas Williams2012-07-301-0/+1
| | | | | | | | | | | | | | | | | This simply adds KADM5_API_VERSION_4 and various fields to the policy structures: - attributes (policy-ish principal attributes) - max_life (max ticket life) - max_renewable_life (max ticket renewable life) - allowed_keysalts (allowed key/salt types) - TL data (future policy extensions) Of these only allowed_keysalts is currently implemented. Some refactoring of TL data handling is also done. ticket: 7223 (new)
* Only store master mey list in DAL handleGreg Hudson2012-03-211-1/+1
| | | | | | | | | | | | | | r24314 (#6778) created a hybrid owernship model for the master key list, with one virtual copy stored in the DAL handle and one provided to the caller of krb5_db_fetch_mkey_list. Replace this with a model where only the DAL handle owns the list, and a caller can get access to an alias pointer with a new function krb5_db_mkey_list_alias(). Functions which previously accepted the master key list as an input parameter now expect to find it in the DAL handle. Patch by Will Fiveash <will.fiveash@oracle.com>. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@25781 dc483132-0cff-0310-8789-dd5450dbe970

| | | | | | | | | | | | Create a new tl-data type to hold the time of the last administrative unlock, and factor it into decisions about account lockout. Since tl-data values are propagated from master to slave, this will cause modprinc -unlock operations to reach slave KDCs on the next propagation. ticket: 6795 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24424 dc483132-0cff-0310-8789-dd5450dbe970
* kdb: store mkey list in context and permit NULL mkey for ↵Sam Hartman2010-09-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | kdb_dbe_decrypt_key_data Previously, code needed to run a loop to find the current master key, possibly fetch a new master key list and try finding the master key again around each key decryption. This was not universally done; there are cases where only the current master key was used. In addition, the correct ideom for decrypting key data is too complicated and is potentially unavailable to plugins that do not have access to the master key. Instead, store the master key list in the dal_handle whenever it is fetched and permit a NULL master key for krb5_dbe_decrypt_key_data. * Remove APIs for krb5_db_{get|set}_mkey_list * krb5_db_fetch_mkey_list: memoize master key list in dal_handle * krb5_db_free_mkey_list: don't free the memoized list; arrange for it to be freed later * krb5_dbe_decrypt_key_data: Search for correct master key on NULL argument * change call sites to take advantage ticket: 6778 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24314 dc483132-0cff-0310-8789-dd5450dbe970

* Handle migration from pre-1.7 databases with master key kvno != 1Greg Hudson2010-01-281-0/+1
| | | | | | | | | | | | | | | | | | | | krb5_dbe_lookup_mkvno assumes an mkvno of 1 for entries with no explicit tl_data. We've seen at least one pre-1.7 KDB with a master kvno of 0, violating this assumption. Fix this as follows: * krb5_dbe_lookup_mkvno outputs 0 instead of 1 if no tl_data exists. * A new function krb5_dbe_get_mkvno translates this 0 value to the minimum version number in the mkey_list. (krb5_dbe_lookup_mkvno cannot do this as it doesn't take the mkey_list as a parameter.) * Call sites to krb5_dbe_lookup_mkvno are converted to krb5_dbe_get_mkvno, except for an LDAP case where it is acceptable to store 0 if the mkvno is unknown. ticket: 6650 target_version: 1.7.1 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23676 dc483132-0cff-0310-8789-dd5450dbe970
