[libvirt] [PATCH 3/8] virstoragefile: Resolve Coverity DEADCODE

Coverity complains that the condition "size + 1 == 0" cannot happen. It's already been determined that offset+size is not larger than buf_size (and buf_size is smaller than UINT_MAX); and also that offset+size didn't overflow. So just remove the check Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- src/util/virstoragefile.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/src/util/virstoragefile.c b/src/util/virstoragefile.c index 5db9184..1a02b18 100644 --- a/src/util/virstoragefile.c +++ b/src/util/virstoragefile.c @@ -393,8 +393,6 @@ qcowXGetBackingStore(char **res, } if (offset + size > buf_size || offset + size < offset) return BACKING_STORE_INVALID; - if (size + 1 == 0) - return BACKING_STORE_INVALID; if (VIR_ALLOC_N(*res, size + 1) < 0) return BACKING_STORE_ERROR; memcpy(*res, buf + offset, size); -- 1.9.3
