The >80 chars long line should be fixed, this patch has worked well for me.

This line is apparently too long. The automatic checks complain about this, sorry.

Like commit 1cf3bfc ("bpf: Support 64-bit pointers to kfuncs") for s390x, add support for 64-bit pointers to kfuncs for LoongArch. Since the infrastructure is already implemented in BPF core, the only thing need to be done is to override bpf_jit_supports_far_kfunc_call(). Before this change, several test_verifier tests failed: # ./test_verifier | grep # | grep FAIL thesofproject#119/p calls: invalid kfunc call: ptr_to_mem to struct with non-scalar FAIL thesofproject#120/p calls: invalid kfunc call: ptr_to_mem to struct with nesting depth > 4 FAIL thesofproject#121/p calls: invalid kfunc call: ptr_to_mem to struct with FAM FAIL thesofproject#122/p calls: invalid kfunc call: reg->type != PTR_TO_CTX FAIL thesofproject#123/p calls: invalid kfunc call: void * not allowed in func proto without mem size arg FAIL thesofproject#124/p calls: trigger reg2btf_ids[reg->type] for reg->type > __BPF_REG_TYPE_MAX FAIL thesofproject#125/p calls: invalid kfunc call: reg->off must be zero when passed to release kfunc FAIL thesofproject#126/p calls: invalid kfunc call: don't match first member type when passed to release kfunc FAIL thesofproject#127/p calls: invalid kfunc call: PTR_TO_BTF_ID with negative offset FAIL thesofproject#128/p calls: invalid kfunc call: PTR_TO_BTF_ID with variable offset FAIL thesofproject#129/p calls: invalid kfunc call: referenced arg needs refcounted PTR_TO_BTF_ID FAIL thesofproject#130/p calls: valid kfunc call: referenced arg needs refcounted PTR_TO_BTF_ID FAIL thesofproject#486/p map_kptr: ref: reference state created and released on xchg FAIL This is because the kfuncs in the loaded module are far away from __bpf_call_base: ffff800002009440 t bpf_kfunc_call_test_fail1 [bpf_testmod] 9000000002e128d8 T __bpf_call_base The offset relative to __bpf_call_base does NOT fit in s32, which breaks the assumption in BPF core. Enable bpf_jit_supports_far_kfunc_call() lifts this limit. Note that to reproduce the above result, tools/testing/selftests/bpf/config should be applied, and run the test with JIT enabled, unpriv BPF enabled. With this change, the test_verifier tests now all passed: # ./test_verifier ...
