Stanislav Fomichev a439184d51 bpf/test_run: fix unkillable BPF_PROG_TEST_RUN for flow dissector ... Syzbot found out that running BPF_PROG_TEST_RUN with repeat=0xffffffff makes process unkillable. The problem is that when CONFIG_PREEMPT is enabled, we never see need_resched() return true. This is due to the fact that preempt_enable() (which we do in bpf_test_run_one on each iteration) now handles resched if it's needed. Let's disable preemption for the whole run, not per test. In this case we can properly see whether resched is needed. Let's also properly return -EINTR to the userspace in case of a signal interrupt. This is a follow up for a recently fixed issue in bpf_test_run, see commit df1a2cb7c7 ("bpf/test_run: fix unkillable BPF_PROG_TEST_RUN").
