| |
Changes in v2:
- Squash a couple of the uasm cleanups.
- Make insn_table_MM const (suggested by Matt Redfearn)
- Put the eBPF in its own source file (should fix build warnings/errors on 32-bit kernel builds).
- Use bpf_jit_binary_alloc() (suggested by Daniel Borkmann)
- Implement tail calls.
- Fix system call tracing to extract arguments for kprobe/__seccomp_filter() tracing (perhaps not really part the the JIT, but necessary to have fun with the samples/bpf programs).
Most things in samples/bpf work, still working on the incantations to build tools/testing/selftests/bpf/ ...
From v1:
The first three patches improve MIPS uasm in preparation for use by the JIT. Then the eBPF JIT implementation.
I am CCing netdev@ and the BPF maintainers for their comments, but would expect Ralf to merge via the MIPS tree if and when it all looks good.
David Daney (5): MIPS: Optimize uasm insn lookup. MIPS: Correctly define DBSHFL type instruction opcodes. MIPS: Add some instructions to uasm. MIPS: Add support for eBPF JIT. MIPS: Give __secure_computing() access to syscall arguments.
