From 388e061ecfe42446d51d8a90dabce6b43fd76167 Mon Sep 17 00:00:00 2001 From: Herakliusz Lipiec Date: Thu, 25 Apr 2019 13:48:17 +0100 Subject: [PATCH] net/tap: fix memory leak on IPC request When sending synchronous IPC requests, the caller must free the response buffer if the request was successful and reply is no longer needed. Fix the code to correctly use the IPC API.
