Subject [Impala-ASF-CR] KUDU-2220: GetEndOfChainX509 does not return end-user cert
Date Tue, 21 Nov 2017 19:17:25 GMT
Hello Alexey Serbin, Kudu Jenkins, Todd Lipcon,

I'd like you to do a code review. Please visit

to review the following change.

Change subject: KUDU-2220: GetEndOfChainX509 does not return end-user cert

KUDU-2220: GetEndOfChainX509 does not return end-user cert

KUDU-2091 introduced a function GetEndOfChainX509() which was supposed
to return the "end-user" certificate. However, the end-user certificate
is not at the end of the chain, but rather at the beginning of the chain
as specificed by the RFC:

  | This is a sequence (chain) of certificates. The sender's certificate MUST
  | come first in the list. Each following certificate MUST directly certify
  | the one preceding it.

This patch fixes this by changing the GetEndOfChainX509() to
GetTopOfChainX509(). An existing test is modified to test this patch. It does
not pass without this change.
