The stub occupies the same region that execve() would create for the original progam. The stub copies everything to a new area, erases the original region, replaces it with the de-compressed program, and erases the copy of itself via the escape hatch. The copy is inexpensive via mmap() of /proc/self/exe. modified: stub/src/i386-linux.elf-entry.S modified: stub/src/i386-linux.elf-fold.S modified: stub/src/i386-linux.elf-main.c modified: p_lx_elf.cpp modified: p_lx_elf.h modified: p_lx_interp.cpp modified: p_lx_interp.h modified: p_lx_sh.cpp modified: p_lx_sh.h modified: p_mach.cpp modified: p_mach.h modified: p_unix.cpp modified: p_unix.h modified: p_vmlinx.cpp plus .h, .map, .dump
