Add From<User> for libc::passwd trait implementation to convert
a User into a libc::passwd
Implementation consumes the User struct, giving ownership over
the internal members to the libc::passwd struct
Add the User::gecos field to 64-bit Android builds, since it is
supported by libc::passwd for those builds

to get the packet drop counter of UDP socket.

Now that Nix's weird error types are eliminated, there's no reason not
to simply use Errno as the Error type.
|
|
For many of Nix's consumers it be convenient to easily convert a Nix
error into a std::io::Error. That's currently not possible because of
the InvalidPath, InvalidUtf8, and UnsupportedOperation types that have
no equivalent in std::io::Error.
However, very few of Nix's public APIs actually return those unusual
errors. So a more useful API would be for Nix's standard error type to
implement Into<std::io::Error>.
This commit makes Error a simple NewType around Errno. For most
functions it's a drop-in replacement. There are only three exceptions:
* clearenv now returns a bespoke error type. It was the only Nix
function whose error couldn't be cleanly mapped onto an Errno.
* sys::signal::signal now returns Error(Errno::ENOTSUP) instead of
Error::UnsupportedOperation when the user passes an incompatible
argument to `handler`.
* When a NixPath exceeds PATH_MAX, it will now return
Error(Errno::ENAMETOOLONG) instead of Error::InvalidPath.
In the latter two cases there is now some abiguity about whether the
error code was generated by Nix or by the OS. But I think the ambiguity
is worth it for the sake of being able to implement Into<io::Error>.
This commit also introduces Error::Sys() as a migration aid. Previously
that as an enum variant. Now it's a function, but it will work in many
of the same contexts as the original.
Fixes #1155

* Fix race conditions in the tests. Two tests were grabbing a mutex but
immediately dropping it. Thank you, Clippy.
* Remove vestigial Windows support. Remove some code added to support
Windows in 2015. Nix is no longer intended to ever run on Windows.
* Various other minor Clippy lints.

* libc::aiocb must not be moved while the kernel has a pointer to it.
This change enforces that requirement by using std::pin.
* Split LioCbBuilder out of LioCb. struct LioCb relied on the
(incorrect) assumption that a Vec's elements have a stable location in
memory. That's not true; they can be moved during Vec::push. The
solution is to use a Vec in the new Builder struct, but finalize it to
a boxed slice (which doesn't support push) before allowing it to be
submitted to the kernel.
* Eliminate owned buffer types. mio-aio no longer uses owned buffers
with nix::aio. There's little need for it in the world of
async/await. I'm not aware of any other consumers. This
substantially simplifies the code.

1439: Add sendfile64 r=asomers a=tdryer
`sendfile64` is a Linux-specific call with a wider type for the `offset` argument than `sendfile`.
This is largely a copy of the existing `sendfile` function and associated test.

It's not available from libc on that platform.

Travis didn't compile check tests on platforms that couldn't run tests
in CI, so they bitrotted. Let's see how bad they are.
Most annoyingly, 32-bit Android defines mode_t as 16 bits, but
stat.st_mode as 32-bits.

This reverts commit c0783e7f8d55a7725179afc1b3c8eeae932d228c.
Now the test should work correctly, so we can re-enable it.

Starting from Linux 5.6, VMADDR_CID_LOCAL is supported to do local
communication (loopback device).
Before Linux 5.6 it was called VMADDR_CID_RESERVED and was not
supported, so we could expect an EADDRNOTAVAIL, but now this address
is supported and handled by the 'vsock_loopback' kernel module loaded
automatically if no other vsock transports are loaded.

1390: pty: Make forkpty() unsafe r=asomers a=tavianator
After the child returns from a fork() of a multi-threaded process, it is
undefined behaviour to call non-async-signal-safe functions according to
POSIX. Since forkpty() is implemented in terms of fork(), those
restrictions should apply to it too.

This is useful to allow returning an iterator based on a directory iterator
without needing a self-referential struct.

Need to use the right cfg option for the conditional compilation.
target_os is the right option to use when targeting FreeBSD. target_env
was used before which seems to be a typo.

Allow nix to compile on Fuchsia by conditionally avoiding libc
functionality that does not exist for Fuchsia.

On Cirrus-CI, this test frequently fails with EINVAL. The error goes
away if I add a line of debugging, so it's probably a timing issue. But
I can't debug it myself.

In older versions of Musl, ttyname_r would wrongly return ENOTTY instead
of EBADF. We expected that bug in our test suite. But Rust
1.37.0 updated Musl to 1.1.22, which fixes the problem. This change
reverts our workaround.

On Cirrus-CI, these tests frequently segfault. It's probably indicative
of a real bug, not just a problem in the tests. But for now we need to
skip them to get CI working.

On OSX, this test has begun to fail in CI on OSX. Presumably it's because
aio_suspend was getting interrupted by a signal.

The test was assuming that once dropped, a temporary file's file
descriptor would be invalid. But it might not be, because another file
might be opened with the same file descriptor. Instead, use an
obviously invalid file descriptor.

Ensure that the exec functions' arguments are valid for 'static.
Previously they were short-lived temporaries.

Travis has been super-slow lately (> 6 hours per build). Cirrus is much
faster: about 20 minutes. Cirrus also has slightly better test
coverage, mainly because it doesn't use SECCOMP.
Also,
* Fix the Redox CI build. The old Travis configuration didn't actually
build for Redox, so we never noticed that Redox can't be built with a
stable compiler. Thanks to @coolreader18 for finding this.
* Disable the udp_offload tests on cross-tested platforms. These tests
are failing with ENOPROTOOPT in Cirrus-CI. I suspect it's due to a
lack of support in QEMU. These tests were skipped on Travis because
its kernel was too old.
* Fix require_kernel_version on Cirrus-CI. Cirrus reports the Linux
kernel version as 4.19.112+, which the semver crate can't handle.
* Fix test_setfsuid on Cirrus. When run on Cirrus, it seems like the
file in /tmp gets deleted as soon as it's closed. Probably an
overzealous temporary file cleaner. Use /var/tmp, because no
temporary file cleaner should run in there.
* Skip mount tests on Cirrus. They fail for an unknown reason.

* Skip the AF_ALG tests on Cirrus-CI

1345: Disable test-aio-drop in GNU environments r=asomers a=asomers
This test occasionally fails in Travis on x86_64-unknown-linux-gnu. The
failure takes the form of the test executable receiving a random signal.
Sometimes SIGHUP, sometimes SIGKILL, etc. I think this must be a bug in
glibc, even though I can't reproduce it in my development environment.
But it interferes with CI too much to leave enabled.
