Subject: [PATCH bpf-next v3 00/10] bpf: enhancements for multi-function programs
Date: Tue, 22 May 2018 22:46:03 +0530 [thread overview]
Message-ID: <cover.1527008646.git.sandipan@linux.vnet.ibm.com> (raw)
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
