[1] Support for bpf-to-bpf function calls in the powerpc64 JIT compiler.
[2] Provide a way for resolving function calls because of the way JITed
images are allocated in powerpc64.
[3] Fix to get JITed instruction dumps for multi-function programs from
the bpf system call.
[4] Fix for bpftool to show delimited multi-function JITed image dumps.
v4:
- Incorporate review comments from Jakub.
- Fix JSON output for bpftool.
v3:
- Change base tree tag to bpf-next.
- Incorporate review comments from Alexei, Daniel and Jakub.
- Make sure that the JITed image does not grow or shrink after
the last pass due to the way the instruction sequence used
to load a callee's address maybe optimized.
- Make additional changes to the bpf system call and bpftool to
make multi-function JITed dumps easier to correlate.
v2:
- Incorporate review comments from Jakub.
Sandipan Das (10):
bpf: support 64-bit offsets for bpf function calls
bpf: powerpc64: pad function address loads with NOPs
bpf: powerpc64: add JIT support for multi-function programs
bpf: get kernel symbol addresses via syscall
tools: bpf: sync bpf uapi header
tools: bpftool: resolve calls without using imm field
bpf: fix multi-function JITed dump obtained via syscall
bpf: get JITed image lengths of functions via syscall
tools: bpf: sync bpf uapi header
tools: bpftool: add delimiters to multi-function JITed dumps
