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
2020-12-23openbsd: fix siginfo_t struct definitionSébastien Marie
`_proc` struct part contains an union for kill/cld parts. see [siginfo_t](https://github.com/openbsd/src/blob/77c6c13150aaa9f0a29fe29b233c4436d1da01c0/sys/sys/siginfo.h#L132)

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.

Before this change, thread local variables were landmines if LLVM decided to optimize any writes to them using vector instructions.

I'm not sure this prefix-free style is a good idea, but let's roll with it for the moment.

2020-12-13std: Fixes for siginfo test on macosLemonBoy
Xnu's sigaction() only supports fetching a limited set of sa_flags, test SA_SIGINFO instead of SA_RESETHAND as that's supported everywhere. Add another check to make sure SA_RESETHAND works. Co-authored-by: Jakub Konka <kubkon@jakubkonka.com>

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.

2020-11-23Fix the ELF base calculationLemonBoy
Find the effective ELF load address in dl_iterate_phdr by computing the difference between the in-memory phdr and its p_vaddr specified in the ELF file. This makes the dl_iterate_phdr test pass and restores the stack traces.
