powerpc64/bpf: Add support for bpf trampolines 2024-10-31T00:00:55+00:00 Naveen N Rao naveen@kernel.org 2024-10-30T07:08:50+00:00 d243b62b7bd3d5314382d3b54e4992226245e936 Add support for bpf_arch_text_poke() and arch_prepare_bpf_trampoline() for 64-bit powerpc. While the code is generic, BPF trampolines are only enabled on 64-bit powerpc. 32-bit powerpc will need testing and some updates. BPF Trampolines adhere to the existing ftrace ABI utilizing a two-instruction profiling sequence, as well as the newer ABI utilizing a three-instruction profiling sequence enabling return with a 'blr'. The trampoline code itself closely follows x86 implementation. BPF prog JIT is extended to mimic 64-bit powerpc approach for ftrace having a single nop at function entry, followed by the function profiling sequence out-of-line and a separate long branch stub for calls to trampolines that are out of range. A dummy_tramp is provided to simplify synchronization similar to arm64. When attaching a bpf trampoline to a bpf prog, we can patch up to three things: - the nop at bpf prog entry to go to the out-of-line stub - the instruction in the out-of-line stub to either call the bpf trampoline directly, or to branch to the long_branch stub. - the trampoline address before the long_branch stub. We do not need any synchronization here since we always have a valid branch target regardless of the order in which the above stores are seen. dummy_tramp ensures that the long_branch stub goes to a valid destination on other cpus, even when the branch to the long_branch stub is seen before the updated trampoline address. However, when detaching a bpf trampoline from a bpf prog, or if changing the bpf trampoline address, we need synchronization to ensure that other cpus can no longer branch into the older trampoline so that it can be safely freed. bpf_tramp_image_put() uses rcu_tasks to ensure all cpus make forward progress, but we still need to ensure that other cpus execute isync (or some CSI) so that they don't go back into the trampoline again.

When attaching a bpf trampoline to a bpf prog, we can patch up to three

- the instruction in the out-of-line stub to either call the bpf trampoline

The only difference now between bpf_jit_emit_func_call_hlp() and bpf_jit_emit_func_call_rel() is in handling of the initial pass where target function address is not known. Fold that logic into bpf_jit_emit_func_call_hlp() and rename it to bpf_jit_emit_func_call_rel() to simplify bpf function call JIT code. We don't actually need to load/restore TOC across a call out to a different kernel helper or to a different bpf program since they all work with the kernel TOC. We only need to do it if we have to call out to a module function. So, guard TOC load/restore with appropriate conditions.
