Subject: RADIUS: Use size_t instead of int for message attributes
X-Git-Tag: hostap_2_10~1587
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=02b43c557c6638327b257c16f3b01aab468e5472;p=thirdparty%2Fhostap.git

RADIUS: Use size_t instead of int for message attributes

While RADIUS messages are limited to 4 kB, use size_t to avoid even a
theoretical overflow issue with 16-bit int.
