Hello Kudu Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/6137
to look at the new patch set (#4).
Change subject: [security] Add per-connection nonce for Kerberos replay
resistance
......................................................................
[security] Add per-connection nonce for Kerberos replay resistance
Kerberos is suceptible to replay attacks, which it attempts to mitigate
by using a server-side replay cache. The cache is not 100% effective,
and is extremely slow. This commit introduces an effective and efficient
method of mitigating replay attacks by using a server-generated nonce
which the client must send back to the server, wrapped in SASL integrity
protection. This will allow Kudu to disable the replay cache without
negatively affecting security.
No tests are provided, but the codepath is well covered by existing
Kerberos negotiation tests. I intend to write simulated mitm tests to
check this and the channel binding protections soon.
