Subject: hivex: allocate_block should update valid block bitmap.
X-Git-Tag: 1.0.83~19
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=3113582ef88d280cfa3c479cc705c3972c777fb7;p=libguestfs.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.
