    A compiler-rt/test/sanitizer_common/TestCases/Linux/get_sock_peer_name.cpp

  Log Message:
  -----------
  [sanitizer] Allow getsockname with NULL addrlen

This is already permitted in getpeername, and returns EFAULT
on Linux (does not crash the program).

Fixes https://github.com/google/sanitizers/issues/1451.
