2020-12-23Truncate user and group ids for 64 bit Linux systems (#7466)Andreas Linz
* Truncate user and group ids Calls to `getuid`, `getgid` and their `eid` variants fail to compile on 64bit Linux systems because the return value of the syscall is of `usize` and needs to be truncated to fit the size of `uid_t` that is 32 bit. Thanks to @FireFox317 for figuring this out in Zig's Discord channel! * Add a regression test for user and group ids * Replace @truncate with @intCast This should be safe because `uid_t` will be 32-bit. * Add missing import for getauxval * Add missing package names * Revert "Add missing import for getauxval" This reverts commit 38f93dc89effdf657f2b81a56b96527ce4083f52. * Skip user and group test if builtin.link_libc
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: Properly fix the TLS alignment problemLemonBoy
ad05509 introduced a fix for the wrong problem, the logic to align the start of main_thread_tls_buffer was already there but was flawed. Fix it for good and avoid wasting too many bytes for alignment purposes.
2020-12-17std: align(16) main_thread_tls_bufferAndrew Kelley
Before this change, thread local variables were landmines if LLVM decided to optimize any writes to them using vector instructions.

2020-11-27Fix fork() on Linux/sparc64Koakuma
fork() on Linux/sparc64 seems to return its result in two registers, with %o0 always holding the current process' PID, and the parent/child status returned in %o1. Add some glue code to convert those into the libc-style return value.

Thanks @daurnimator for catching this.

This is the part of #3960 that has to be rewritten to apply to latest master branch code.

Conflicts: lib/std/dynamic_library.zig (fixed in this commit) src/all_types.hpp src/codegen.cpp src/link.cpp src/main.cpp Will manually apply the diffs to these deleted files to the new zig code in a followup commit.

2020-11-05std: Split kernel&libc definitions of stat structLemonBoy
There's no guarantee for the kernel definition to be ABI compatible with the libc one (and vice versa). There's also no guarantee of ABI compatibility between musl/glibc. Fun, isn't it?

2020-10-21std: Slim down the error code path in initStaticTLSLemonBoy
Calling @panic made the executable ~30x times bigger, use a simple `abort()` and let the user figure out what went wrong. Supporting ARMv6 (and earlier?) platforms is not a priority. Closes #6676

2020-10-04Split openat/close test into two separate testsJoran Dirk Greef
If an older kernel fails the `openat` test because of `AT_FDCWD` then we don't want to skip the `close` test.

2020-10-04Allow for advanced non-sequential SQE allocation schemesJoran Dirk Greef
Decouples SQE queueing and SQE prepping methods to allow for non-sequential SQE allocation schemes as suggested by @daurnimator. Adds essential SQE prepping methods from liburing to reduce boilerplate. Removes non-essential .link_with_next_sqe() and .use_registered_fd().

2020-10-04Expose available kernel featuresJoran Dirk Greef
2020-10-03Use load acquire semantics when reading the SQPOLL wakeup flagJoran Dirk Greef
Ensures that the wakeup flag is read after the tail pointer has been written. It's important to use memory load acquire semantics for the flags read, otherwise the application and the kernel might not agree on the consistency of the wakeup flag, leading to I/O starvation.
