Subject: hivex: allocate_block should update valid block bitmap.
X-Git-Tag: 1.1.0~22
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=d5e1a21afc6a5245b31e0017317c76aa1864e874;p=hivex.git

hivex: allocate_block should update valid block bitmap.

The internal allocate_block() function wasn't updating the bitmap,
so if you revisited a block which you had allocated in the same
session, you could get an EFAULT error.
