Subject: [PATCH 5/5] index-pack: correct "offset" type in unpack_entry_data()
Date: Tue, 5 Jul 2016 19:05:58 +0200 [thread overview]
Message-ID: <20160705170558.10906-6-pclouds@gmail.com> (raw)
In-Reply-To: <20160705170558.10906-1-pclouds@gmail.com>
unpack_entry_data() receives an off_t value from unpack_raw_entry(),
which could be larger than unsigned long on 32-bit systems with large
file support. Correct the type so truncation does not happen. This
only affects bad object reporting though.
