Subject: array: Number of items in get_size() is unsigned
X-Git-Tag: 5.1.0~26
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=116363e5c639be5e35483ad72ac275e5cfaee4eb;p=thirdparty%2Fstrongswan.git

array: Number of items in get_size() is unsigned

Otherwise, array->esize is promoted to int and if array->esize * num
results in a value > 0x7fffffff the return value would be incorrect due
the implicit sign extension when getting cast to size_t.
