| Brad Bishop | 1a4b7ee | 2018-12-16 17:11:34 -0800 | [diff] [blame] | 1 | This problem was created by the upstream commit 78708b7c8c |
| 2 | After applying the commit, it will send SIGINT to the process group(-signal_pid). |
| 3 | But if we use gdbserver send SIGINT, and the attached process is not a process |
| 4 | group leader, then the "kill (-signal_pid, SIGINT)" returns error and fails to |
| 5 | interrupt the attached process. |
