[ Upstream commit f6131f28057d4fd8922599339e701a2504e0f23d ]
The cgroup testing relies on the root cgroup's subtree_control setting,
If the 'memory' controller isn't set, all test cases will be failed
as following:
$ sudo ./test_memcontrol
not ok 1 test_memcg_subtree_control
not ok 2 test_memcg_current
ok 3 # skip test_memcg_min
not ok 4 test_memcg_low
not ok 5 test_memcg_high
not ok 6 test_memcg_max
not ok 7 test_memcg_oom_events
ok 8 # skip test_memcg_swap_max
not ok 9 test_memcg_sock
not ok 10 test_memcg_oom_group_leaf_events
not ok 11 test_memcg_oom_group_parent_events
not ok 12 test_memcg_oom_group_score_events
To correct this unexpected failure, this patch write the 'memory' to
subtree_control of root to get a right result.

The test_core will skip the
test_cgcore_no_internal_process_constraint_on_threads test case if the
'cpu' controller missing in root's subtree_control. In fact we need to
set the 'cpu' in subtree_control, to make the testing meaningful.

From: Xin Long <lucien.xin@gmail.com>
[ Upstream commit 67c0aaa1eaec60e9dab301012bdebe6726ae04bd ]
sysctl setting bc_forwarding for $rp2 is needed when ping_test_from h2,
otherwise the bc packets from $rp2 won't be forwarded. This patch is to
add this setting for $rp2.
Also, as ping_test_from does grep "$from" only, which could match some
unexpected output, some test case doesn't really work, like:
# ping_test_from $h2 198.51.200.255 198.51.200.2
PING 198.51.200.255 from 198.51.100.2 veth3: 56(84) bytes of data.
64 bytes from 198.51.100.1: icmp_seq=1 ttl=64 time=0.336 ms
When doing grep $form (198.51.200.2), the output could still match.
So change to grep "bytes from $from" instead.
Fixes: 40f98b9af943 ("selftests: add a selftest for directed broadcast forwarding")
