Shamir seals now come in two varieties: legacy and new-style. Legacy
Shamir is automatically converted to new-style when a rekey operation
is performed. All new Vault initializations using Shamir are new-style.
New-style Shamir writes an encrypted master key to storage, just like
AutoUnseal. The stored master key is encrypted using the shared key that
is split via Shamir's algorithm. Thus when unsealing, we take the key
fragments given, combine them into a Key-Encryption-Key, and use that
to decrypt the master key on disk. Then the master key is used to read
the keyring that decrypts the barrier.
* Initial work
* rework
* s/dr/recovery
* Add sys/raw support to recovery mode (#7577)
* Factor the raw paths out so they can be run with a SystemBackend.
# Conflicts:
# vault/logical_system.go
* Add handleLogicalRecovery which is like handleLogical but is only
sufficient for use with the sys-raw endpoint in recovery mode. No
authentication is done yet.
* Integrate with recovery-mode. We now handle unauthenticated sys/raw
requests, albeit on path v1/raw instead v1/sys/raw.
* Use sys/raw instead raw during recovery.
* Don't bother persisting the recovery token. Authenticate sys/raw
requests with it.
* RecoveryMode: Support generate-root for autounseals (#7591)
* Recovery: Abstract config creation and log settings
* Recovery mode integration test. (#7600)
* Recovery: Touch up (#7607)
* Recovery: Touch up
* revert the raw backend creation changes
* Added recovery operation token prefix
* Move RawBackend to its own file
* Update API path and hit it using CLI flag on generate-root
* Fix a panic triggered when handling a request that yields a nil response. (#7618)
* Improve integ test to actually make changes while in recovery mode and
verify they're still there after coming back in regular mode.
* Refuse to allow a second recovery token to be generated.
* Resize raft cluster to size 1 and start as leader (#7626)
* RecoveryMode: Setup raft cluster post unseal (#7635)
* Setup raft cluster post unseal in recovery mode
* Remove marking as unsealed as its not needed
* Address review comments
* Accept only one seal config in recovery mode as there is no scope for migration
* Save the original request body for forwarding
If we are forwarding a request after initial parsing the request body is
already consumed. As a result a forwarded call containing a request body
will have the body be nil. This saves the original request body for a
given request via a TeeReader and uses that in cases of forwarding past
body consumption.
* Add helper for checking if an error is a fatal error
The double-double negative was really confusing, and this pattern is used a few places in Vault. This negates the double negative, making the devx a bit easier to follow.
* Check return value of UnsealWithStoredKeys in sys/init
* Return proper error types when attempting unseal with stored key
Prior to this commit, "nil" could have meant unsupported auto-unseal, a transient error, or success. This updates the function to return the correct error type, signaling to the caller whether they should retry or fail.
* Continuously attempt to unseal if sealed keys are supported
This fixes a bug that occurs on bootstrapping an initial cluster. Given a collection of Vault nodes and an initialized storage backend, they will all go into standby waiting for initialization. After one node is initialized, the other nodes had no mechanism by which they "re-check" to see if unseal keys are present. This adds a goroutine to the server command which continually waits for unseal keys to exist. It exits in the following conditions:
- the node is unsealed
- the node does not support stored keys
- a fatal error occurs (as defined by Vault)
- the server is shutting down
In all other situations, the routine wakes up at the specified interval and attempts to unseal with the stored keys.
* Provide base64 keys in addition to hex encoded.
Accept these at unseal/rekey time.
Also fix a bug where backup would not be honored when doing a rekey with
no operation currently ongoing.
