### Integrated Storage panic related to old TLS key
|

|
Raft in Vault uses its own set of TLS certificates, independent of those that the user
|
|
|
|
|
controls to protect the API port and those used for replication and clustering. These
|
|
|
|
|
certs get rotated daily, but to ensure that nodes which were down or behind on Raft log
|
|
|
|
|
replication don't lose the ability to speak with other nodes, the newly generated daily
|
|
|
|
|
TLS cert only starts being used once we see that all nodes have received it.
|
|
|
|
|
|
|
|
|
|
A recent security audit related change results in this rotation code [getting a
|
|
|
|
|
panic](https://github.com/hashicorp/vault/issues/15147) when the current cert is
|
|
|
|
|
more than 24h old. This can happen if the cluster as a whole is down for a day
|
|
|
|
|
or more. It can also happen if a single node is unreachable 24h, or sufficiently
|
|
|
|
|
backlogged in applying raft logs that it's more than a day behind.
|
|
|
|
|
|
|
|
|
|
Impacted versions: 1.10.1, 1.9.5, 1.8.10. Versions prior to these are unaffected.
|
|
|
|
|
|
|
|
|
|
New releases addressing this panic are coming soon.
