Subject: rar: Do not forcefully set offset to unpacked size
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f3949062edd13da3d0ac330d3226871350f3ff6b;p=thirdparty%2Flibarchive.git

rar: Do not forcefully set offset to unpacked size

If an entry reaches its end of file, the offset is not necessarily
the same as unp_size. This is especially true for links which have
a "0 size body" even though the unpacked size is not 0.
