ipv4: Remove all uses of LL_ALLOCATED_SPACE
commit 660882432909dbe611f1792eda158188065cb9f1 upstream.
ipv4: Remove all uses of LL_ALLOCATED_SPACE
The macro LL_ALLOCATED_SPACE was ill-conceived. It applies the
alignment to the sum of needed_headroom and needed_tailroom. As
the amount that is then reserved for head room is needed_headroom
with alignment, this means that the tail room left may be too small.
This patch replaces all uses of LL_ALLOCATED_SPACE in net/ipv4
with the macro LL_RESERVED_SPACE and direct reference to
needed_tailroom.
This also fixes the problem with needed_headroom changing between
allocating the skb and reserving the head room.
