             Summary: Make it possible to reliably inject environment variables into forked processes
                 Key: MESOS-8229
                 URL: https://issues.apache.org/jira/browse/MESOS-8229
             Project: Mesos
          Issue Type: Improvement
          Components: agent, containerization, master
            Reporter: Benjamin Bannier


We should consider supporting reliable injection of environment variables into forked processes, e.g., to customize dynamic library loading with {{LD_PRELOAD}} or the influence the behavior of the used runtime (e.g., glibc options). Customary, environment variables are used for this, but we tend to in many cases strip away all but a hardcoded set of flags (e.g., when starting executors). The possible set of these flags seems to be open.

I came across this when trying to run our test suites with a build with clang address sanitization enabled (passing {{-fsanitize=address}} in the compiler flags). This links in a C runtime which aborts processes if memory leaks are detected. These aborts can be disabled by passing runtime options in an environment variable {{ASAN_OPTIONS}}, but unfortunately, it is not effective in all forked processes.
