[External] Kernel panic when running bpf selftest cases

Hi,

I pull master branch code from upstream, and try to run bpf self test
cases.  The kernel panics when running tunnel related cases.
It seems that the kernel panics when calling the function
"_xfrm_get_state".  Could someone help to check this ?

The output message is as follows:
"
# [60] FUNC _xfrm_get_state type_id=59
# [61] VAR _version type_id=15 linkage=1
# [62] INT char size=1 bits_offset=0 nr_bits=8 encoding=SIGNED
# [63] ARRAY (anon) type_id=62 index_type_id=6 nr_elems=4
# [64] VAR _license type_id=63 linkage=1
# [65] DATASEC license size=0 vlen=1 size == 0
