This avoids invoking the NVMe kernel driver with invalid IP addresses and getting error messages in the syslog. +- The Avahi driver will now print an error message if the same IP address is found on multiple interfaces. This indicates a misconfiguration of the network. Bug fixes: * For TCP transport: use `sysfs` controller `src_addr` attribute when matching to a configured "candidate" controller. This is to determine when an existing controller (located under the `sysfs`) can be reused instead of creating a new one. This avoids creating unnecessary duplicate connections. * Udev event handling: use `systemctl restart` instead of `systemctl start`. There is a small chance that a `start` operation has not completed when a new `start` is required. Issuing a `start` while a `start` is being performed has no effect. However, a `restart` will be handled properly. +* `stafd`: Do not delete and recreate DC objects on kernel events indicating that an nvme device associated to a discovery controller was removed by the kernel. This was done to kick start the reconnect process, but was also causing the DLPE (Discovery Log Page Entries) cache to be lost. This could potentially result in `stacd` disconnecting from I/O controllers. Instead, keep the existing DC object which contains a valid DLPE cache and simply restart the "retry to connect" timer. This way the DLPE cache is maintained throughout the reconnect to DC process. ## Changes with release 2.2.3 |
