native-rustposix

Tools to compile native applications with the RustPOSIX library OS

Building

Pull this repo, then

export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH

Then compile the program by make test or make perf-test, for example.

Write a c program

• #include "lind_platform.h" at top
• lindrustinit(0) at begining of main, lindrustfinalize() in the end
• calling lind syscalls, with the last parameter the cage number. Witout forking, we always use cage number 1.
• lind_fork merely duplicates the metadata of a cage, we still need to use native pthread_create to really spawn a new thread, in conjunction with lind_fork. Note that we still need to keep track of cage numbers outselves, and be careful about the heap and data, as there are no memory isolation at all.
• to make lind_fork work correctly, we also need to call rustposix_thread_init(1, 0) at the begining of main, as NaCl also call this to register the main thread of the App being started.

pipe-cages Example

Running pipe-cages

./pipe-cages {log2 of write buffer size} {log2 of read buffer size}

If no argument provided, the default is 16 for both args

NOTE!

The OUTLOOP = 1UL << 4 is just 8, so we will iterate the outer loop for 8 times, 8 * 2^30 bits = 1 GigaByte
