Concerning ssh, this setup contains the following security issue. Since |

candidate. |
| 331 | 331 |
- Whether the master candidate's certificate digest match their entry |
| 332 | 332 |
in the candidate map. |
| 333 |
- Whether no node tries to use the certificate of another node. In |
|
| 334 |
particular, it is important to check that no normal node tries to |
|
| 335 |
use the certificate of a master candidate. |

Crypto renewal |

renewed (among others). Option ``--new-cluster-certificate`` renews the |
| 341 | 344 |
node daemon certificate only. |
| 342 | 345 |
|
| 343 |
Additionally to the renewal of the node daemon server certificate, we |
|
| 344 |
propose to renew all client certificates when ``gnt-cluster |
|
| 345 |
renew-crypto`` is called without another option. |
|
| 346 |
|
|
| 347 | 346 |
By adding an option ``--new-node-certificates`` we offer to renew the |
| 348 |
client certificates only. Whenever the client certificates are renewed, the
|
|
| 347 |
client certificate. Whenever the client certificates are renewed, the |
|
| 349 | 348 |
candidate map has to be updated and redistributed. |
| 350 | 349 |
|
| 351 |
If for whatever reason there is an entry in the candidate map of a node |
|
| 352 |
that is not a master candidate (for example due inconsistent updating |
|
| 353 |
after a demotion or offlining), we offer the user to remove the entry |
|
| 354 |
from the candidate list (for example if cluster verify detects this |
|
| 355 |
inconsistency). We propose to implement a new option called |
|
| 356 |
|
|
| 357 |
:: |
|

gnt-cluster renew-crypto --update-candidate-map |

TODO: describe what exactly should happen here |
|

If for whatever reason, the candidate map becomes inconsistent, for example |
|
| 351 |
due inconsistent updating after a demotion or offlining), the user can use |
|
| 352 |
this option to renew the client certificates and update the candidate |
|
| 353 |
certificate map. |
