2013-10-09[snmp/agent] enable SNMP to create missing database directoriesSteve Vinoski
Add {db_init_error, create_db_and_dir} option to SNMP manager and agent. This allows them to create any missing parent directories for db_dir, rather than treating any missing directories as a fatal error. The default for db_init_error, which is terminate, is unchanged. Add create_db_and_dir to the documentation. Add new tests to verify that using create_db_and_dir results in missing parent directories being created.

Add utility functions for checking view masks. Code cleanup, function renaming and comment fix (%% instead of %). Also updated the mask check in the vacm config file check function. Finally, release notes and some cosmetic changes to the agent config-file(s) user guide chapter.

2013-06-10SNMP/VACM: bugfix for vacmViewTreeFamilyMaskStefan Zegenhagen
Dear all, it's almost a year since I sent the patch attached to this e-mail, and I just found out that I have not yet gotten a response to it. I would consider this patch important because it fixes an issue with the interpretation of data that might be critical for SNMPv3 operation. I confirmed at that time that erlangs interpretation of vacmViewTreeFamilyMask is indeed not interoperable with other SNMP stacks. Kind regards, > > > the implementation of SNMP-VIEW-BASED-ACM.mib assumes that the input for > > > vacmViewTreeFamilyMask is an OID consisting of 1's and 0's only to form > > > the mask. However, the MIB states that the input should be a bitstring. > > > > > > The OID representation of the mask is useful in the code as it speeds up > > > time-critical code paths when checking access permissions for EACH SNMP > > > access. Reading/writing the view mask objects is less time-critical. > > > > > > Therefore, to fix the issue, convert between OID representation and > > > bitstring when the vacmViewTreeFamilyMask objects are accessed. This is > > > done by the patch attached to this e-mail. > > > I'm very sorry for the troubles that I am causing but it seems that the > previous version of the patch did more than it should: the OID-bitstring > conversion was also applied to other tables in the same MIB on > get/get-next requests. > > The version of the patch that is attached to this e-mail restricts the > OID-bitstring conversion to vacmViewTreeFamilyMask alone. -- Dr. Stefan Zegenhagen arcutronix GmbH Garbsener Landstr. 10 30419 Hannover Germany Tel: +49 511 277-2734 Fax: +49 511 277-2709 Email: [email protected] Web: www.arcutronix.com *Synchronize the Ethernet* General Managers: Dipl.

However, the MIB implementation assumed the latter, effectively rendering all attempts to read/set masks via SNMP unsuccessful. Since the mask is used in hot paths (e.g. access permission checks for each SNMP operation, the OID representation of the mask has benefits (e.g. faster processing). Therefore, convert the bitstring to/from its OID representation when reading/setting any mask object.

2013-05-24[snmp/agent] Improved mib-storage ets module error handlingMicael Karlberg
Also fixed some of the debug printouts.
2013-05-23[snmp/agent] Handle mib-storage ets module non-ex fileMicael Karlberg
Make sure snmpa_mib_storage_ets can handle a non-ex file whe n openning a table (it should simply create it).
2013-05-23[snmp/agent] Updated open options for the mnesia mib-storage moduleMicael Karlberg
Updated the snmpa_mib_storage_mnesia module to handle alias atoms for the nodes option. Also, (git) added mib-storage behaviour ref-man.

2013-05-22[snmp/agent] Add default value for mib_storage for sub-agentMicael Karlberg
When starting a sub-agent we previously did not provide a value for mib_storage, which was alright because ets was assumed as a default in every place where it was used. Now we expect the value to be defined and therefor we must explicitly add the default value for sub-agents when staring them.
