Fix memory errors when trim causes testcase growth ( #881 ) ( #903 )
...
* Revert "fixed potential double free in custom trim (#881 )"
This reverts commit e9d2f72382cab75832721d859c3e731da071435d.
* Revert "fix custom trim for increasing data"
This reverts commit 86a8ef168dda766d2f25f15c15c4d3ecf21d0667.
* Fix memory errors when trim causes testcase growth
Modify trim_case_custom to avoid writing into in_buf because
some custom mutators can cause the testcase to grow rather than
shrink.
Instead of modifying in_buf directly, we write the update out
to the disk when trimming is complete, and then the caller is
responsible for refreshing the in-memory buffer from the file.
This is still a bit sketchy because it does need to modify q->len in
order to notify the upper layers that something changed, and it could
end up telling upper layer code that the q->len is *bigger* than
the buffer (q->testcase_buf) that contains it, which is asking
for trouble down the line somewhere...
* Fix an unlikely situation
Put back some `unlikely()` calls that were in
the e9d2f72382cab75832721d859c3e731da071435d commit that was
reverted.
