LTP has over 3800 test cases. Some test cases are not suitable for testing LTS kernel on Ampere platform, e.g:
- Test cases depending on architectures other than aarch64
- Not useful for server system
All test groups in ltp/runtest are added to ltp_cmdfile by default.

Use https://github.com/AmpereComputing/ampere-lts-kernel/blob/main/tests/lkft/ltp/skipfile-lkft.yaml to control:
E.g: due to missing configurations, ltp test framework does not run the test. These test cases are counted in the LTP test result as Skipped, e.g: "Total tests 3554, Skipped 223, Failures 106"
| Test set | Why skipped | Comments |
|---|---|---|
| io_cd | Need cd media | |
| io_floppy | Need floppy disk |
The cause for the failure is listed in: https://docs.google.com/spreadsheets/d/1kNXjuFW_OxsNXR1kxfbeIOhodwRRf8S8xdy0YSKD2l8/edit#gid=2004818483
Ampere-lts ltp testcase revise (4).xlsx
$ wget https://github.com/AmpereComputing/ampere-lts-kernel/archive/refs/heads/main.zip
$ unzip main.zip; cd ampere-lts-kernel-main/tests/
$ ./runall.sh <--- this will run both kernel-selftest and ltp. You can edit this script to run ltp only.
LTP result depends on OS version, OS configuration, kernel version and config. It is common some test case passed on some kernel, but failed on another.
We start by running a single test case:
e.g, we observed some unexpected skip case:
net_stress.ipsec_tcp,tcp4_ipsec01,SKIP,32
net_stress.ipsec_tcp,tcp4_ipsec02,SKIP,32
net_stress.ipsec_tcp,tcp4_ipsec03,SKIP,32
net_stress.ipsec_tcp,tcp4_ipsec04,SKIP,32
Try to run this single test:
# ./runltp -f net_stress.ipsec_tcp -s tcp4_ipsec01
... ...

Next, we debug tcp_ipsec.sh:
+++ echo add local addr fd00:1:1:1::2/64
add local addr fd00:1:1:1::2/64
+++ ip addr add fd00:1:1:1::2/64 dev ltp_ns_veth2 nodad <------------------- this is where error happens

Check my kernel boot option, there is:
ipv6.disable=1
Remove this option and reboot. Fine.
