1739: ppoll: make sigmask parameter optional r=rtzoeller a=stefano-garzarella ppoll(2) supports 'sigmask' as NULL. In that case no signal mask manipulation is performed.

2022-06-07Fix the test_acct testAlan Somers
It has never actually executed its command, so the only reason that it ever worked is that on most systems there are usually processes starting and exiting all the time.

2022-05-14Rewrite the aio moduleAlan Somers
The existing AIO implementation has some problems: 1) The in_progress field is checked at runtime, not compile time. 2) The mutable field is checked at runtime, not compile time. 3) A downstream lio_listio user must store extra state to track whether the whole operation is partially, completely, or not at all submitted. 4) Nix does heap allocation itself, rather than allowing the caller to choose it. This can result in double (or triple, or quadruple) boxing. 5) There's no easy way to use lio_listio to submit multiple operations with a single syscall, but poll each individually. 6) The lio_listio usage is far from transparent and zero-cost. 7) No aio_readv or aio_writev support. 8) priority has type c_int; should be i32 9) aio_return should return a usize instead of an isize, since it only uses negative values to indicate errors, which Rust represents via the Result type. This rewrite solves several problems: 1) Unsolved. I don't think it can be solved without something like C++'s guaranteed type elision. It might require changing the signature of Future::poll too. 2) Solved. 3) Solved, by the new in_progress method and by removing the complicated lio_listio resubmit code. 4) Solved. 5) Solved. 6) Solved, by removing the lio_listo resubmit code. It can be reimplemented downstream if necessary. Or even in Nix, but it doesn't fit Nix's theme of zero-cost abstractions. 7) Solved. 8) Solved. 9) Solved. The rewrite includes functions that don't work on FreeBSD, so add CI testing for FreeBSD 14 too. By default only enable tests that will pass on FreeBSD 12.3. But run a CI job on FreeBSD 14 and set a flag that will enable such tests.

1643: Replace the IoVec struct with IoSlice and IoSliceMut from the standard library r=asomers a=notgull As per discussion in #1637, the `IoVec<&[u8]>` and `IoVec<&mut [u8]>` types have been replaced with `std::io::IoSlice` and `IoSliceMut`, respectively. Notable changes made in this pull request include: - The complete replacement of `IoVec` with `IoSlice*` types in both public API, private API, and tests. - Replacing `IoVec` with `IoSlice` in docs. - Replacing `&[IoVec<&mut [u8]>]` with `&mut [IoSliceMut]`, note that the slice requires a mutable reference now. This is how it's done in the standard library, and there might be a soundness issue in doing it the other way. Resolves #1637 Co-authored-by: not_a_seagull <notaseagull048@gmail.com>

2022-03-23Make `uname` always safeJan Bujak
This fixes several issues with the current `uname` bindings: - Do not ignore `uname` errors; at least on glibc `uname` can fail, so now it returns a `Result` instead of assuming that the call will always succeed. - Do not assume `uname` will initialize every member of `utsname`; not every implementation initializes every field, so internally the struct is now zero-initialized. - Do not blindly assume strings returned by `uname` will always be valid UTF-8; `UtsName`'s accessors will now return `&OsStr`s instead of `&str`s.
2022-03-22Deprecate IpAddr, Ipv4Addr, and Ipv6AddrAlan Somers
Because they're redundant with types in the standard library. Fixes #1681
2022-03-21Replace the Sockaddr enum with a unionAlan Somers
The SockAddr enum is quite large, and the user must allocate space for the whole thing even though he usually knows what type he needs. Furthermore, thanks to the sa_family field, the sockaddr types are basically an enum even in C. So replace the ungainly enum with a SockaddrLike trait implemented by all sockaddr types and a SockaddrStorage union that has safe accessors. Also, deprecate InetAddr, which only existed to support SockAddr. Supplants #1504 Fixes #1544

2022-03-09wait: implement waitid()Matthias Schiffer
waitid() has a number of additional features that waitpid() is missing: - WNOWAIT is only accepted for waitid() on Linux (and possibly other platforms) - Support for waiting on PID file descriptors on Linux For now support is added for all platforms with waitid() that have proper siginfo_t support in libc. NetBSD support is currently a work in progress [1]. Tests for the signal/exit code are currently skipped on MIPS platforms due to bugs in qemu-user's translation of siginfo_t (fixed in [2] and [3]; the second fix is not in a released qemu version yet).

2022-01-22Better type safety for mqueueAlan Somers
On some platforms, mqd_t is a pointer. That means code like the below can trigger a segfault. Fix it by defining a Newtype around mqd_t that prevents use-after-free and dangling pointer scenarios. ```rust fn invalid_mqd_t() { let mqd: libc::mqd_t = std::ptr::null_mut(); mq_close(mqd).unwrap(); } ``` Also, get test coverage for mqueue in CI on FreeBSD.

2022-01-02Fix intermittency in test_timer::alarm_firesAlan Somers
The test was disabling the signal handler before disabling the timer. Fix intermittent failures by: * Reversing the cleanup order. * Sleeping for a while before removing the signal handler, since POSIX does not guarantee that timer_delete will clear pending signals. Also, speed up the timer to make the test suite complete faster.
