2020-12-18std.crypto.random: introduce fork safetyAndrew Kelley
Everybody gets what they want! * AT_RANDOM is completely ignored. * On Linux, MADV_WIPEONFORK is used to provide fork safety. * On pthread systems, `pthread_atfork` is used to provide fork safety. * For systems that do not have the capability to provide fork safety, the implementation falls back to calling getrandom() every time. * If madvise is unavailable or returns an error, or pthread_atfork fails for whatever reason, it falls back to calling getrandom() every time. * Applications may choose to opt-out of fork safety. * Applications may choose to opt-in to unconditionally calling getrandom() for every call to std.crypto.random.fillFn. * Added `std.meta.globalOption`. * Added `std.os.madvise` and related bits. * Bumped up the size of the main thread TLS buffer. See the comment there for justification. * Simpler hot path in TLS initialization.

2020-12-18std: tlcsprng: cleanups & improvementsAndrew Kelley
* get rid of the pointless fences * make seed_len 16 instead of 32, which is accurate since it was already padding the rest anyway; now we do 1 pad instead of 2. * secureZero to clear the AT_RANDOM auxval * add a flag root source files can use to disable the start code. This is in case people want to opt out of the initialization when they don't depend on it.

2020-12-18start code: overwrite AT_RANDOM after we use itAndrew Kelley
2020-12-18std: introduce a thread-local CSPRNG for general useAndrew Kelley
std.crypto.random * cross platform, even freestanding * can't fail. on initialization for some systems requires calling os.getrandom(), in which case there are rare but theoretically possible errors. The code panics in these cases, however the application may choose to override the default seed function and then handle the failure another way. * thread-safe * supports the full Random interface * cryptographically secure * no syscall required to initialize on Linux (AT_RANDOM) * calls arc4random on systems that support it `std.crypto.randomBytes` is removed in favor of `std.crypto.random.bytes`. I moved some of the Random implementations into their own files in the interest of organization. stage2 no longer requires passing a RNG; instead it uses this API. Closes #6704
2020-11-24make start code more versatileAndrew Kelley
* always align the stack to 16. I saw an instance on x86_64 linux where it was needed. * detect at runtime if being interpreted by a dynamic loader and if so avoid clobbering the fs register.

2020-11-16start.zig: call wWinMain with root's typeJonathan Marler
I have an alternative set of windows bindings I'm working on: https://github.com/marler8997/zig-os-windows. So I'm declaring my wWinMain function with my own HINSTANCE type rather than the one from std.os.windows. This change allows start to call wWinMain using any pointer type.

2020-10-22Fix Compiler Error When Using wWinMain Entry-PointDixiE
The fix for #6715 introduced a new compiler error when attempting to use wWinMain as the application entry-point. The Windows API often relies on implicit casts between signed and unsigned variables. In this case, wWinMain returns an INT despite the fact this value is intended to feed into ExitProcess, which expects a UINT, so I've restored the bitcast from #5613.
2020-10-19std: Minor changes to startup codeLemonBoy
* Smaller startup sequence for ppc64 * Terminate the frame-pointer chain when executing _start * Make the stack traces work on ppc64 * Make the stack traces coloured on ppc64, some ioctls numbers are different and the whole set of constants should be audited.

2020-07-01Implement std.start for powerpc64leShawn Anastasio
This is a bit hacky since we end up doing more than just grabbing the stack pointer in the inline assembly block. Ideally _start would be implemented in pure asm for powerpc64le, but this will do for now. Still to be implemented is powerpc, powerpc64, and powerpc64 (ELFv2) support. The latter will just require correctly determing target ABI for powerpc64 and enabling the existing powerpc64le implementation for it.

2020-02-28introduce operating system version ranges as part of the targetAndrew Kelley
* re-introduce `std.build.Target` which is distinct from `std.Target`. `std.build.Target` wraps `std.Target` so that it can be annotated as "the native target" or an explicitly specified target. * `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a struct which has the tag as well as version range information. * `std.elf` gains some more ELF header constants. * `std.Target.parse` gains the ability to parse operating system version ranges as well as glibc version. * Added `std.Target.isGnuLibC()`. * self-hosted dynamic linker detection and glibc version detection. This also adds the improved logic using `/usr/bin/env` rather than invoking the system C compiler to find the dynamic linker when zig is statically linked. Related: #2084 Note: this `/usr/bin/env` code is work-in-progress. * `-target-glibc` CLI option is removed in favor of the new `-target` syntax. Example: `-target x86_64-linux-gnu.2.27` closes #1907
