Add x86_64-linux-gnu emulator I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4

Fix link order in cosmopolitan.a It turned out that the linker was doing the wrong with the amalgamation library concerning weak stubs. A regression test has been added and new binaries have been uploaded to https://justine.lol/cosmopolitan/ Ideally this should be fixed by building a tool that turns multiple .a files into a single .a file with deduplication. As a workaround for now the cosmopolitan.a build is restructured to not include LIBC_STUBS which meant technical debt needed to be paid off where non-stub interfaces were moved to LIBC_INTRIN and LIBC_NEXGEN32E. Thank @PerfectProductions in #31 for the report!

LIBC_INTRIN \
Make C memory safe like Rust This change enables Address Sanitizer systemically w/ `make MODE=dbg`. Our version of Rust's `unsafe` keyword is named `noasan` which is used for two functions that do aligned memory chunking, like `strcpy.c` and we need to fix the tiny DEFLATE code, but that's it everything else is fabulous you can have all the fischer price security blankets you need Best of all is we're now able to use the ASAN data in Blinkenlights to colorize the memory dumps. See the screenshot below of a test program: https://justine.lol/blinkenlights/asan.png Which is operating on float arrays stored on the stack, with red areas indicating poisoned memory, and the green areas indicate valid memory.

Support non-blocking i/o across platforms This change introduces new tests for `O_NONBLOCK` and `SOCK_NONBLOCK` to confirm that non-blocking i/o is now working on all supported platforms, including Windows. For example, you can now say on Windows, MacOS, etc.: socket(AF_INET, SOCK_STREAM | SOCK_NONBLOCK, IPPROTO_TCP); To create a non-blocking IPv4 TCP socket. Or you can enable non-blocking i/o on an existing socket / pipe / etc. file descriptor by calling fcntl fcntl(fd, F_SETFL, fcntl(fd, F_GETFL) | O_NONBLOCK); This functionality is polyfilled on older Linux kernels too, e.g. RHEL5. Now that fcntl() support is much better the FIOCLEX / FIONCLEX polyfills for ioctl() have been removed since they're ugly non-POSIX diameond APIs This change fixes a weakness in kprintf() that was causing Windows trace tools to frequently crash.

Make garbage collection thread safe - You can now use _gc(malloc()) in multithreaded programs - This change fixes a bug where fork() on NT disabled TLS - Fixed TLS code morphing on XNU/NT, for R8-R15 registers

LIBC_LOG \
Prevent Make from talking to public Internet This change introduces the nointernet() function which may be called to prevent a process and its descendants from communicating with publicly routable Internet addresses. GNU Make has been modified to always call this function. In the future Landlock Make will have a way to whitelist subnets to override this behavior, or disable it entirely. Support is available for Linux only. Our firewall does not require root access. Calling nointernet() will return control to the caller inside a new process that has a SECCOMP BPF filter installed, which traps network related system calls. Your original process then becomes a permanent ptrace() supervisor that monitors all processes and threads descending from the returned child. Whenever a networking system call happens the kernel will stop the process and wakes up the monitor, which then peeks into the child memory to read the sockaddr_in to determine if it's ok. The downside to doing this is that there can be only one supervisor at a time using ptrace() on a process. So this firewall won't be enabled if you run make under strace or inside gdb. It also makes testing tricky.

Greatly expand system() shell code features The cosmopolitan command interpreter now has 13 builtin commands, variable support, support for ; / && / || syntax, asynchronous support, and plenty of unit tests with bug fixes. This change fixes a bug in posix_spawn() with null envp arg. strace logging now uses atomic writes for scatter functions. Breaking change renaming GetCpuCount() to _getcpucount(). TurfWar is now updated to use the new token bucket algorithm. WIN32 affinity masks now inherit across fork() and execve().
