filter: add minimal BPF JIT image disassembler This is a minimal stand-alone user space helper, that allows for debugging or verification of emitted BPF JIT images. This is in particular useful for emitted opcode debugging, since minor bugs in the JIT compiler can be fatal. The disassembler is architecture generic and uses libopcodes and libbfd. How to get to the disassembly, example: 1) `echo 2 > /proc/sys/net/core/bpf_jit_enable` 2) Load a BPF filter (e.g. `tcpdump -p -n -s 0 -i eth1 host 192.168.20.0/24`) 3) Run e.g. `bpf_jit_disasm -o` to disassemble the most recent JIT code output `bpf_jit_disasm -o` will display the related opcodes to a particular instruction as well. Example for x86_64: $ ./bpf_jit_disasm 94 bytes emitted from JIT compiler (pass:3, flen:9) ffffffffa0356000 + <x>: 0: push %rbp 1: mov %rsp,%rbp 4: sub $0x60,%rsp 8: mov %rbx,-0x8(%rbp) c: mov 0x68(%rdi),%r9d 10: sub 0x6c(%rdi),%r9d 14: mov 0xe0(%rdi),%r8 1b: mov $0xc,%esi 20: callq 0xffffffffe0d01b71 25: cmp $0x86dd,%eax 2a: jne 0x000000000000003d 2c: mov $0x14,%esi 31: callq 0xffffffffe0d01b8d 36: cmp $0x6,%eax [...] 5c: leaveq 5d: retq $ ./bpf_jit_disasm -o 94 bytes emitted from JIT compiler (pass:3, flen:9) ffffffffa0356000 + <x>: 0: push %rbp 55 1: mov %rsp,%rbp 48 89 e5 4: sub $0x60,%rsp 48 83 ec 60 8: mov %rbx,-0x8(%rbp) 48 89 5d f8 c: mov 0x68(%rdi),%r9d 44 8b 4f 68 10: sub 0x6c(%rdi),%r9d 44 2b 4f 6c [...] 5c: leaveq c9 5d: retq c3 Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: David S.

tools/: Convert to new topic libraries Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where the Makefile lives and then we place the headers in subdirs. For example, all the fs-related stuff goes to tools/lib/api/fs/ from which we get libapikfs.a (acme got almost the naming he wanted :-)) and we link it into the tools which need it - in this case perf and tools/vm/page-types. acme: "Looking at the implementation, I think some tools can even link directly to the .o files, avoiding the .a file altogether. But that is just an optimization/finer granularity tools/lib/ cherrypicking that toolers can make use of." Fixup documentation cleaning target while at it.
