2020-01-28Prevent arbitrary size allocation when sending UDS messages.Dean Deng
Currently, Send() will copy data into a new byte slice without regard to the original size. Size checks should be performed before the allocation takes place. Note that for the sake of performance, we avoid putting the buffer allocation into the critical section. As a result, the size checks need to be performed again within Enqueue() in case the limit has changed. PiperOrigin-RevId: 292058147

2020-01-28Prefer Type& over Type &Michael Pratt
And Type* over Type *. This is basically a whitespace only change. gVisor code already prefers left-alignment of pointers and references, but clang-format formats for consistency with the majority of a file, and some files leaned the wrong way. This is a one-time pass to make us completely conforming. Autogenerated with: $ find . \( -name "*.cc" -or -name "*.c" -or -name "*.h" \) \ | xargs clang-format -i -style="{BasedOnStyle: Google, \ DerivePointerAlignment: false, PointerAlignment: Left}" PiperOrigin-RevId: 291972421
