** Description changed:
- There are failed cases in the xfrm_policy.sh test, but the overall result is
PASS
+ [Impact]
+ Even with failed cases reported in the xfrm_policy.sh test, the overall
result is still "PASS"

$ echo $?
0
This is because of the variable "lret" in check_xfrm() is not a local
variable, and it looks like it will override the one in
check_exceptions() thus making the return value become 0 for the passed
test case after the failed one.
+
+ [Fix]
+ * f6e9ceb7a7fc32 (" selftests: xfrm: fix test return value override issue in
xfrm_policy.sh")
+
+ This patch can be cherry-picked into all of the affected kernels.
+
+ Focal kernel got this patch via stable update, and we don't have this
+ test in Bionic.
+
+ [Test]
+ Run the xfrm_policy.sh test, if there is any failed cases the final result
will not be 0.
+
+ [Regression Potential]
+ This change is just for testing tools, it's unlikely to affect real kernel
functionality. However it's expected to generate failures in our test report as
it's reflecting the real test result.
