====================
pull-request: bpf 2018-01-18
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a divide by zero due to wrong if (src_reg == 0) check in
64-bit mode. Properly handle this in interpreter and mask it
also generically in verifier to guard against similar checks
in JITs, from Eric and Alexei.
2) Fix a bug in arm64 JIT when tail calls are involved and progs
have different stack sizes, from Daniel.
3) Reject stores into BPF context that are not expected BPF_STX |
BPF_MEM variant, from Daniel.
4) Mark dst reg as unknown on {s,u}bounds adjustments when the
src reg has derived bounds from dead branches, from Daniel.
