[LTP] LTP network test case failed.

[samir mulani]

Hi Team,

The following network-related test cases are failing. Could anyone help me
to understand why they are failing?
*Platform*: SUSE
command used: Under /opt/ltp
-> ./runltp -f net.features

sctp01                                             FAIL       1
Error: sctp01 2 TFAIL: performance result is -342% < threshold -200%
sctp01_ipv6                                        FAIL       1
Error: sctp01 1 TFAIL: performance result is -1887% < threshold -200%
Error: sctp01 2 TFAIL: performance result is -347% < threshold -200%
macsec01                                           FAIL       1
macsec01 1 TFAIL: performance result is -309% < threshold -100%
macsec01 1 TFAIL: performance result is -315% < threshold -100%
macsec01 1 TFAIL: performance result is -298% < threshold -100%
macsec01 1 TFAIL: performance result is -309% < threshold -100%
macsec01 1 TFAIL: performance result is -288% < threshold -100%
macsec01 1 TFAIL: performance result is -301% < threshold -100%

 Following is a common observation for all three test cases:

macsec01 2 TINFO: AppArmor enabled, this may affect test results
macsec01 2 TINFO: it can be disabled with TST_DISABLE_APPARMOR=1 (requires
super/root)
macsec01 2 TINFO: loaded AppArmor profiles: none

Is it correct that to pass the above three test cases, AppArmor needs to be
disabled?
There are a few error logs observed in AppArmor logs when the above three
test cases are run,
/org/opensuse/Network/Interface/252.getManagedObjects failed. Server
responds:
May 23 06:42:31 localhost wickedd-nanny[824]:
org.freedesktop.DBus.Error.UnknownMethod: Method "GetManagedObjects" with
signature "" on interface "org.freedesktop.DBus.ObjectManager" doesn't exist


Thanks,
Samir M.
