parking_lot provides synchronization primitives which aren't
poisoned on panic. This makes it easier to determine which tests
are failing, as a test failure no longer causes all subsequent tests
using that mutex to fail.
|
|
Ensure file descriptors are nonnegative and less than `FD_SETSIZE`.
(Fixes #1572.)

libc::posix_fadvise returns errnos directly rather than in the errno
variable.

Test: `cargo test --test test test_pollfd_events`
|
|
This was an oversight from #1306.

1496: Rework UnixAddr to fix soundness issues r=asomers a=coolreader18
Fixes #1494
I went with making `sun_path` always nul-terminated since that just seems to make things easier, since (at least according to linux man pages) `sockaddr_un`s returned by the kernel will always be nul-terminated.

1509: Allow Android to use timerfd r=asomers a=rtzoeller
This is a continuation of #1336 which also enables the timerfd tests.

1516: Implement AsRawFd for PollFd r=asomers a=cemeyer
Implement the trait on PollFd, providing an `as_raw_fd()` accessor to
get the RawFd associated with the PollFd.
Subsumes #1147, #1286. Closes #1146.

1317: test_af_alg_aead waits indefinitely r=asomers a=ritzk
Starting with linux kernel 4.9, the crypto interface changed slightly such that the authentication tag memory is only needed in the output buffer for encryption and in the input buffer for decryption. Thus, we have fewer bytes to read than the buffer size. Do not block on read.
alternatively, we can adjust the decrypted buffer size based on kernel version ( ">= 4.9") to not include auth_size .
```
if kernel_version >= "4.9":
let mut decrypted = vec![0u8; payload_len + (assoc_size as usize) ];
```
before
```
test sys::test_socket::test_af_alg_aead ... test sys::test_socket::test_af_alg_aead has been running for over 60 seconds
```
after
```
test sys::test_socket::test_af_alg_aead ... ok
```

Setting these options enables receiving errors, such as ICMP errors from
the network, via `recvmsg()` with `MSG_ERRQUEUE`.
Adds new `Ipv{4,6}RecvErr` variants to `ControlMessageOwned`. These
control messages are produced when `Ipv4RecvErr` or `Ipv6RecvErr`
options are enabled on a raw or datagram socket.
New tests for the functionality can be run with `cargo test --test test
test_recverr`.
This commit builds on an earlier draft of the functionality authored by
Matthew McPherrin <git@mcpherrin.ca>.

1506: Test Linux aarch64 on real aarch64 hardware. r=asomers a=asomers
Co-authored-by: Alan Somers <asomers@gmail.com>

Apparently AWS Graviton containers don't support it. socket() retunrs
EAFNOSUPPORT in that environment.
Also, be more selective about skipping tests under QEMU
Instead of skipping them on architectures where we happen to use QEMU,
only skip them when QEMU is actually being used.

|
|
|
Also, split the overbroad test_mknod_family into two tests

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

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.
