Subject: [PATCH 04/24] libxt_quota: make sure uint64 is not truncated
Date: Wed, 25 May 2011 01:08:05 +0200 [thread overview]
Message-ID: <1306278506-11463-5-git-send-email-jengelh@medozas.de> (raw)
In-Reply-To: <1306278506-11463-1-git-send-email-jengelh@medozas.de>
From: JP Abgrall <jpa@google.com>
The xtables_strtoul() would cram a long long into a long.
The parse_int would try to cram a UINT64 into a long.
