Subject: libxt_quota: make sure uint64 is not truncated
X-Git-Tag: v1.4.11~1^2~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2305d5fb42fc059f38fc1bdf53411dbeecdb310b;p=thirdparty%2Fiptables.git

libxt_quota: make sure uint64 is not truncated

The xtables_strtoul() would cram a long long into a long.
The parse_int would try to cram a UINT64 into a long.
