treewide: Use sizeof_field() macro

2019-12-09T18:36:44+00:00

Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except at places where these are defined. Later patches will remove the unused definition of FIELD_SIZEOF(). This patch is generated using following script: EXCLUDE_FILES="include/linux/stddef.h|include/linux/kernel.h" git grep -l -e "\bFIELD_SIZEOF\b" | while read file; do if [[ "$file" =~ $EXCLUDE_FILES ]]; then continue fi sed -i -e 's/\bFIELD_SIZEOF\b/sizeof_field/g' $file; done Signed-off-by: Pankaj Bharadiya Link: https://lore.kernel.org/r/20190924105839.110713-3-pankaj.laxminarayan.bharadiya@intel.com Co-developed-by: Kees Cook Signed-off-by: Kees Cook Acked-by: David Miller # for net

bpf: sparc64: Enable sparc64 jit to provide bpf_line_info

2018-12-20T01:04:53+00:00

This patch enables sparc64's bpf_int_jit_compile() to provide bpf_line_info by calling bpf_prog_fill_jited_linfo(). Signed-off-by: Martin KaFai Lau Acked-by: David S. Miller Signed-off-by: Daniel Borkmann

sparc: Adjust bpf JIT prologue for PSEUDO calls.

2018-11-27T08:46:52+00:00

Move all arguments into output registers from input registers. This path is exercised by test_verifier.c's "calls: two calls with args" test. Adjust BPF_TAILCALL_PROLOGUE_SKIP as needed. Let's also make the prologue length a constant size regardless of the combination of ->saw_frame_pointer and ->saw_tail_call settings. Signed-off-by: David S. Miller Signed-off-by: Daniel Borkmann

sparc: Correct ctx->saw_frame_pointer logic.

2018-11-27T01:52:29+00:00

We need to initialize the frame pointer register not just if it is seen as a source operand, but also if it is seen as the destination operand of a store or an atomic instruction (which effectively is a source operand). This is exercised by test_verifier's "non-invalid fp arithmetic" Signed-off-by: David S. Miller Signed-off-by: Alexei Starovoitov

sparc: Fix JIT fused branch convergance.

2018-11-27T01:48:36+00:00

On T4 and later sparc64 cpus we can use the fused compare and branch instruction. However, it can only be used if the branch destination is in the range of a signed 10-bit immediate offset. This amounts to 1024 instructions forwards or backwards. After the commit referenced in the Fixes: tag, the largest possible size program seen by the JIT explodes by a significant factor. As a result of this convergance takes many more passes since the expanded "BPF_LDX | BPF_MSH | BPF_B" code sequence, for example, contains several embedded branch on condition instructions. On each pass, as suddenly new fused compare and branch instances become valid, this makes thousands more in range for the next pass. And so on and so forth. This is most greatly exemplified by "BPF_MAXINSNS: exec all MSH" which takes 35 passes to converge, and shrinks the image by about 64K. To decrease the cost of this number of convergance passes, do the convergance pass before we have the program image allocated, just like other JITs (such as x86) do.
