Subject: P2P: Clear GO negotiation results from stack after use
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6efcc17cb8ff4660ccf586f3028665d976f17ecb;p=thirdparty%2Fhostap.git

P2P: Clear GO negotiation results from stack after use

struct p2p_go_neg_results contains private keys, so clear it from stack
explicitly to avoid leaving any unnecessary copies of keys in memory.
