From 7171a0b0cf5792fd549b601c84b274cd5e4155ed Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Wed, 13 Jul 2016 17:44:00 +0200 Subject: index-pack: correct "len" type in unpack_data() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On 32-bit systems with large file support, one entry could be larger than 4GB and overflow "len". Correct it so we can unpack a full entry.
