From: George Guo <[email protected]>
Some test_progs cases cannot pass on LoongArch and otherwise fail the
run. Add a deny list mirroring the other architectures:
- arena_atomics: the JIT gates atomic operations on arena pointers
(bpf_jit_supports_insn() rejects BPF_ATOMIC in the arena case), so
the verifier rejects these programs early and the skeleton fails to
load. Observed on LoongArch:
13: (db) r3 = atomic64_fetch_add((u64 *)(r2 +0), r3)
BPF_ATOMIC stores into R2 arena is not allowed
... failed to load: -EACCES
