shill: dhcp: Tolerate early dhcpcd exit When the shill process is killed (e.g., during shutdown) a terminate signal is sent to the shill process group, which includes the dhcpcd process. As the two processes race to exit, it is common that the dhcpcd process is already gone by the time shill attempts to release its lease and kill the dhcpcd subprocess. Neither of these errors are worthy of concern, since it is known ahead of time that we are in the process of stopping dhcpcd when these errors occur. BUG=chromium:498908 TEST=Unit tests (for regression) TEST="restart shill; grep dhcp /var/log/messages" TEST=Should contain no messages of the form: TEST="dhcpcd daemon appears to have already exited" or TEST="No such process" Change-Id: I48d2e63c9793eb7f635d2973d931e94c5e8227a2 Reviewed-on: https://chromium-review.googlesource.com/277136 Reviewed-by: mukesh agrawal <quiche@chromium.org> Reviewed-by: Zeping Qiu <zqiu@chromium.org> Tested-by: Paul Stewart <pstew@chromium.org> Commit-Queue: Paul Stewart <pstew@chromium.org>
