Subject: exec: close stdout and stderr streams on child signal
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Frpcd.git;a=commitdiff_plain;h=10f787881da2dc6aac261a2ee3b5eedc0f8b5b54

exec: close stdout and stderr streams on child signal

This prevents timing out ubus call when the child invokes further detached
childs inheriting stdio descriptors.
