Disable execve for select processes
───────────────────────────────────

libnoexecve.so is expected to be listed in /etc/ld.so.preload or manually
injected through LD_PRELOAD env variable, for example with systemd:

Environment=LD_PRELOAD=/.noexec/libnoexecve.so

Once it is active, it will examine /proc/self/exe.  If this file has
an extended attribute "user.noexecve", it will install a seccomp
handler which blocks execve (and execveat, if defined at compilation
time).  You can set such an extended attribute on a program with:

  setfattr -n user.noexecve <program>

setfattr is part of the attr package.

Alternatively, the library blocks all execve() calls if the /proc/self/cmdline
param contains "java".
