Revision 1.5, Mon Jul 27 06:52:48 2020 UTC (7 months ago) by gson
Branch: MAIN
CVS Tags: HEAD
Changes since 1.4: +13 -6 lines

Instead of just skipping interfaces that are "up", skip the whole
repeated_updown test case unless explicitly enabled with "atf-run -v
run_unsafe=yes".  Gratuitously configuring interfaces "up" is no more
safe than gratuitously configuring them "down"; for example, it could
lead to accidentally connecting to an insecure network or diverting
traffic from the desired route.
