From 63df98fa78c8a6e12b40ebdc5c155838d2bf8b5f Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Thu, 29 Nov 2018 18:00:23 -0800 Subject: [PATCH 11/11] gdbserver ctrl-c handling This problem was created by the upstream commit 78708b7c8c After applying the commit, it will send SIGINT to the process group(-signal_pid). But if we use gdbserver send SIGINT, and the attached process is not a process group leader, then the "kill (-signal_pid, SIGINT)" returns error and fails to interrupt the attached process.
