  "message": "selftests/bpf: Reject graph kptr use after RCU unlock\n\nAdd a sleepable verifier test that loads a graph-node local kptr in an\nexplicit RCU read-side critical section, then passes its node to\nbpf_rbtree_remove() after the section ends.\n\nBefore the verifier fix, the stale NON_OWN_REF flag makes the node look like\na live borrowed reference and the program is accepted. After the fix, the\npointer is demoted without NON_OWN_REF and the graph kfunc argument is\nrejected.\n\nAlso exercise a graph kptr loaded while a spin lock provides implicit RCU\nprotection. The pointer must be invalidated when the lock is released, which\nguards the required ordering between non-owning-reference invalidation and\nRCU demotion.\n\nUpdate the existing fault-protected load test state description. The\npost-unlock pointer no longer carries NON_OWN_REF, but remains readable\nbecause the load is rewritten to use BPF_PROBE_MEM.\n\nSigned-off-by: Kumar Kartikeya Dwivedi \u003cmemxor@gmail.com\u003e\nLink: https://lore.kernel.org/r/20260904084325.52250-7-memxor@gmail.com\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\n\n",
