In commit d618d09a68e4 ("tipc: enforce valid ratio between skb truesize
and contents") we introduced a test for ensuring that the condition
truesize/datasize <= 4 is true for a received buffer. Unfortunately this
test has two problems.
- Because of the integer arithmetics the test
if (skb->truesize / buf_roundup_len(skb) > 4) will miss all
ratios [4 < ratio < 5], which was not the intention.
- The buffer returned by skb_copy() inherits skb->truesize of the
original buffer, which doesn't help the situation at all.
In this commit, we change the ratio condition and replace skb_copy()
with a call to skb_copy_expand() to finally get this right.
