4 | Subject: [PATCH] babeld: close stdout once the background daemon is created | ||
5 | |||
6 | Upstream-Status: pending | ||
7 | |||
8 | Once babald becomes a background daemon, it should not output information to | ||
9 | stdout, so need to close stdout. | ||
10 | |||
11 | In fact, other daemons close their stdout when they run into background, like | ||
12 | ospfd, isisd and bgpd, by calling daemon() which is in lib/daemon.c | ||
13 | |||
14 | Closing the stdout can fix a tee hang issue { #/usr/sbin/babeld -d |tee tmp } | ||
