There is one interesting bug:
Test 2224 (ovn -- dhcpv4 : 1 HV, 2 LS, 2 LSPs/LS) constantly fails
with 'CFLAGS=-march=native'. All other tests works normally.
Environment:
* OVS current master:
commit d59831e9b08e ("bridge: No QoS configured is not an error")
* Red Hat Enterprise Linux Server release 7.2 (Maipo)
* Compiler: gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-4)
* Intel(R) Xeon(R) CPU E5-2690 v3
Test scenario:
1. Checkout current master branch.
2. Configure OVS with default configuration:
# ./boot.sh && ./configure && make
3. Check test #2224
# make check TESTSUITEFLAGS='2224'
2224: ovn -- dhcpv4 : 1 HV, 2 LS, 2 LSPs/LS ok
4. Clean up
# make distclean
5. Configure OVS with '-march=native':
# ./boot.sh && ./configure CFLAGS="-march=native" && make
6. Check test #2224
# make check TESTSUITEFLAGS='2224'
2224: ovn -- dhcpv4 : 1 HV, 2 LS, 2 LSPs/LS FAILED
(ovn.at:3205)
Test failed because of bad packet:
./ovn.at:3205: cat 1.packets | cut -c 53-
