It was my understanding at -the time that the BPF test suite was passing & JITing a comparable -number of tests to our cBPF JIT [1], but it turns out that was not the -case. - -The eBPF JIT has a number of problems on MIPS32: - -- Most notably various code paths still result in emission of MIPS64 - instructions which will cause reserved instruction exceptions & kernel - panics when run on MIPS32 CPUs. - -- The eBPF JIT doesn't account for differences between the O32 ABI used - by MIPS32 kernels versus the N64 ABI used by MIPS64 kernels. Notably - arguments beyond the first 4 are passed on the stack in O32, and this - is entirely unhandled when JITing a BPF_CALL instruction. Stack space - must be reserved for arguments even if they all fit in registers, and - the callee is free to assume that stack space has been reserved for - its use - with the eBPF JIT this is not the case, so calling any - function can result in clobbering values on the stack & unpredictable - behaviour. Function arguments in eBPF are always 64-bit values which - is also entirely unhandled - the JIT still uses a single (32-bit) - register per argument. As a result all function arguments are always - passed incorrectly when JITing a BPF_CALL instruction, leading to - kernel crashes or strange behavior. - -- The JIT attempts to bail our on use of ALU64 instructions or 64-bit - memory access instructions. The code doing this at the start of - build_one_insn() incorrectly checks whether BPF_OP() equals BPF_DW, - when it should really be checking BPF_SIZE() & only doing so when - BPF_CLASS() is one of BPF_{LD,LDX,ST,STX}. This results in false - positives that cause more bailouts than intended, and that in turns - hides some of the problems described above. - -- The kernel's cBPF->eBPF translation makes heavy use of 64-bit eBPF - instructions that the MIPS32 eBPF JIT bails out on, leading to most - cBPF programs not being JITed at all. - -Until these problems are resolved, revert the removal of the cBPF JIT -performed by commit 716850ab104d ("MIPS: eBPF: Initial eBPF support for -MIPS32 architecture."). Together with commit f8fffebdea75 ("MIPS: BPF: -Disable MIPS32 eBPF JIT") this restores MIPS32 BPF JIT behavior back to -the same state it was prior to the introduction of the broken eBPF JIT -support. - -[1] https://lore.kernel.org/linux-mips/MWHPR2201MB13583388481F01A422CE7D66D4410@MWHPR2201MB1358.namprd22.prod.outlook.com/ - -Signed-off-by: Paul Burton -Fixes: 716850ab104d ("MIPS: eBPF: Initial eBPF support for MIPS32 architecture.") -Cc: Daniel Borkmann -Cc: Hassan Naveed -Cc: Tony Ambardar -Cc: bpf@vger.kernel.org -Cc: netdev@vger.kernel.org -Cc: linux-mips@vger.kernel.org -Cc: linux-kernel@vger.kernel.org ---- - arch/mips/Kconfig | 1 + - arch/mips/net/Makefile | 1 + - arch/mips/net/bpf_jit.c | 1270 +++++++++++++++++++++++++++++++++++ - arch/mips/net/bpf_jit_asm.S | 285 ++++++++ - 4 files changed, 1557 insertions(+) - create mode 100644 arch/mips/net/bpf_jit.c - create mode 100644 arch/mips/net/bpf_jit_asm.S - ---- a/arch/mips/Kconfig -+++ b/arch/mips/Kconfig -@@ -46,6 +46,7 @@ config MIPS - select HAVE_ARCH_TRACEHOOK - select HAVE_ARCH_TRANSPARENT_HUGEPAGE if CPU_SUPPORTS_HUGEPAGES - select HAVE_ASM_MODVERSIONS -+ select HAVE_CBPF_JIT if !64BIT && !CPU_MICROMIPS - select HAVE_EBPF_JIT if 64BIT && !CPU_MICROMIPS && TARGET_ISA_REV >= 2 - select HAVE_CONTEXT_TRACKING - select HAVE_COPY_THREAD_TLS ---- a/arch/mips/net/Makefile -+++ b/arch/mips/net/Makefile -@@ -1,4 +1,5 @@ - # SPDX-License-Identifier: GPL-2.0-only - # MIPS networking code - -+obj-$(CONFIG_MIPS_CBPF_JIT) += bpf_jit.o bpf_jit_asm.o - obj-$(CONFIG_MIPS_EBPF_JIT) += ebpf_jit.o ---- /dev/null -+++ b/arch/mips/net/bpf_jit.c -@@ -0,0 +1,1270 @@ -+/* -+ * Just-In-Time compiler for BPF filters on MIPS -+ * -+ * Copyright (c) 2014 Imagination Technologies Ltd. -+ * Author: Markos Chandras -+ * -+ * This program is free software;
