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.
|
|
|
|
|
