From 4bb9af48ca36605424c57b6af27dd5e5c827395f Mon Sep 17 00:00:00 2001 From: Liangbin Lian Date: Tue, 14 May 2019 23:20:45 +0800 Subject: lua: lnum: fix strtoul based number parsing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lua's LNUM patch currently doesn't parse properly certain numbers as it's visible from the following simple tests. On x86_64 host (stock Lua 5.1.5, expected output): $ /usr/bin/lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)' 2147483648 8796093022208 4294967296 On x86_64 host: $ staging_dir/hostpkg/bin/lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)' -2147483648 0 0 On x86_64 target: $ lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)' -2147483648 0 0 On ath79 target: $ lua -e 'print(0x80000000); print(0x80000000000); print(0x100000000)' -2147483648 8796093022208 4294967296 It's caused by two issues fixed in this patch, first issue is caused by unhadled strtoul overflow and second one is caused by the cast of unsigned to signed Lua integer when parsing from hex literal.
