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.

2020-11-27Fix 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.

2020-11-05std: 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?

2020-11-01"The Traveling Wilburys' - Handle With Care"Joran Dirk Greef
Both `offset` and `len` are `off_t`. Like the rest of the std lib we assume that `_FILE_OFFSET_BITS == 64` is always true, so that `off_t` is a `u64`. When passing to 32-bit kernels, we split these into two `u32` parameters.

2020-10-27std.os.linux.accept/accept4: allow null for addr and lenjohnLate
std.os.accept already wants to allow null, which matches `man 3p accept`: > address Either a null pointer, or a pointer to a sockaddr structure > where the address of the connecting socket shall be re‐ > turned. > > address_len Either a null pointer, if address is a null pointer, or a > pointer to a socklen_t object which on input specifies the > length of the supplied sockaddr structure, and on output > specifies the length of the stored address. Fixes ziglang#6832.

* improve docs * add TODO comments for things that don't have open issues * remove redundant namespacing of struct fields * guard against ioctl returning EINTR * remove the general std.os.ioctl function in favor of the specific ioctl_SIOCGIFINDEX function. This allows us to have a more precise error set, and more type-safe API.
