Subject: [PATCH v2 0/8] bpf powerpc: Add BPF_PROBE_MEM support in powerpc JIT compiler
Date: Fri, 17 Sep 2021 21:00:39 +0530 [thread overview]
Message-ID: <20210917153047.177141-1-hbathini@linux.ibm.com> (raw)
Patch #1 & #2 are simple cleanup patches. Patch #3 refactors JIT
compiler code with the aim to simplify adding BPF_PROBE_MEM support.
Patch #4 introduces PPC_RAW_BRANCH() macro instead of open coding
branch instruction. Patch #5 & #7 add BPF_PROBE_MEM support for PPC64
& PPC32 JIT compilers respectively. Patch #6 & #8 add explicit
addr > TASK_SIZE_MAX check to handle bad userspace pointers for
PPC64 & PPC32 cases respectively.
