Subject: [PATCH 1/1] journal: fix HMAC calculation when appending a data
|
|
object
|
|
|
|
Since commit 5996c7c295e073ce21d41305169132c8aa993ad0 (v190 !), the
|
|
calculation of the HMAC is broken because the hash for a data object
|
|
including a field is done in the wrong order: the field object is
|
|
hashed before the data object is.
|
|
|
|
However during verification, the hash is done in the opposite order as
|
|
objects are scanned sequentially.
|
|
|
|
(cherry picked from commit 33685a5a3a98c6ded64d0cc25e37d0180ceb0a6a)
