How would I get access to the Coverity results?
You ask. :)
I feel the block layer
is scoring a bit too high here... :-)
Well, five of those are simply new unchecked uses of strstart that
Coverity complains about and I've muted them so you're already down to
0.5. :)
Most of the problems are overflows caused by int32 multiplications (such
as number of sectors * 512, or number of clusters * clusters per sector)
before casting to int64. Many of them probably cannot really happen,
because one of the factor is small and related to the size of an L2
table; for example the number of sectors could be the size of an L2
table, or the number of clusters could be the number of entries in an L2
table.
