On Linux, if the signal trampoline code is in the C library, sigaction
sets the SA_RESTORER flag (0x04000000) in the sa_flags field of old
sigaction (see sigreturn(2)).
This is not intended for application use and is missing from SaFlags,
therefore from_bits fails and unwrapping panics the user program.
This fix just drops the bits that are not defined in SaFlags.

820: Change AioCb to primarily use Bytes instead of Rc<[u8]> r=Susurrus a=asomers
`Rc<[u8]>` isn't a very good buffer type to use for aio. For one thing, it lacks interior mutability. For another, a single `Rc<[u8]>` can't be carved up into smaller buffers of the same type. `Bytes` and `BytesMut` fix both problems. This PR removes the ability to construct an `AioCb` from `Rc<[u8]>` and adds the ability to construct one from `Bytes`, `BytesMut`, or raw pointers (for consumers who need even more flexibility). At this stage, the PR has the following warts:
1. A hack is necessary to force small `Bytes` buffers to allocate on the heap. I plan to fix this with an enhancement to the bytes crate.
2. The `AioCb::buffer` method is necessary due to a deficiency in the tokio-core crate. Once I fix that, then only `AioCb::into_buffer`will need to be public.

It's not actually safe to read into an `Rc<[u8]>`. It only worked
because of a coincidental `unsafe` block. Replace that type with
`BytesMut` from the bytes crate. For consistency's sake, use `Bytes`
for writing too, and completely remove methods relating to `Rc<[u8]>`.
Note that the `AioCb` will actually own the `BytesMut` object. The
caller must call `into_buffer` to get it back once the I/O is complete.
Fixes #788

`pause` will always return `-1` as a result and sets `errno` to
`EINTR`, which indicates that a signal was caught by the process. Since
this is the point of `pause` return an error here makes little sense.
Closes #827.

More Rusty to use &X and &mut X where X is a container type.

It's unclear why these were static in the first place.
|
|
As of Rust 1.17 'static lifetimes are implied when
declaring consts.

Several tests make the assumption that all data is written, which
is not guaranteed with write(), so use write_all() instead.

799: Fix nix on Dragonfly r=Susurrus a=mneumann
This commit replaces pull request https://github.com/nix-rust/nix/pull/684. It fixes building `nix` on DragonFly. All tests pass. This requires most recent libc to build: https://github.com/rust-lang/libc/pull/851.
|

* DragonFly does not have a O_DSYNC flag
* Fix type_of_cmsg_data on DragonFly
* No fexecve() on DragonFly
* Do not run aio test cases on DragonFly
* Keep target lists in alphabetical order
* Unscrable #[cfg] directives and use cfg_if! macro instead
* Fix errno on DragonFly
Below follows an explanation why we have to use a C extension
to get errno working on DragonFly:
DragonFly uses a thread-local errno variable, but #[thread_local] is
feature-gated and not available in stable Rust as of this writing (Rust
1.21.0). We have to use a C extension (src/errno_dragonfly.c) to access
it.
Tracking issue for `thread_local` stabilization:
https://github.com/rust-lang/rust/issues/29594
Once this becomes stable, we can remove build.rs, src/errno_dragonfly.c,
remove the build-dependency from Cargo.toml, and use:
extern {
#[thread_local]
static errno: c_int;
}
Now all targets will use the build.rs script, but only on DragonFly this
will do something. Also, there are no additional dependencies for
targets other than DragonFly (no gcc dep).

741: Expose `decode` on `WaitStatus` and make it return a `Result` r=Susurrus a=rocallahan
Closes #740.

cc #664 (unsure if this is everything needed)

The libc_bitflags! macro was replaced with a non-recursive one supporting
only public structs. I could not figure out how to make the old macro work
with the upgrade, so I reworked part of the bitflags! macro directly to suit
our needs, much as the original recursive macro was made. There are no uses
of this macro for non-public structs, so this is not a problem for internal code.
|

This introduces an `as_abstract()` getter to `UnixAddr` in order to
retrieve the name of an abstract unix socket.
This also adds tests around abstract addresses and clarify docs,
adding explicit semantics.

773: Add more accessors for AioCb r=asomers a=asomers
|
|
This fixes the following warning during run of cargo test
warning: variable does not need to be mutable
--> test/sys/test_aio.rs:16:13
|
16 | fn poll_aio(mut aiocb: &mut AioCb) -> Result<()> {
| ^^^^^^^^^
|
= note: #[warn(unused_mut)] on by default
|
|
|
|
Previously, the `AioCb`'s `in_progress` field would erroneously be set
to `true`, even if the syscall had an error
Fixes #714
|
|
Printing a warning message to stderr isn't really appropriate, because
there's no way to guarantee that stderr is even valid. Nor is
aio_suspend necessarily an appropriate action to take.

746: Replace socket FFI with libc versions r=asomers a=Susurrus
Getting this up there to get some CI run on it. Replacing the `msghdr`, `cmsghdr`, and other FFI function declarations will be a little more involved so I wanted to run this through first.
|
|
745: Use upstream libc definitions for fcntl FFI r=asomers a=Susurrus
|
|
|
|
Used the libc_enum! macro to create enums for the ptrace event, request, and libc_bitflags for options constants defined in libc.
Also, replicated functionality to move from c_int to PtraceEvent enum in PR #728 as it appears to be abandoned.
Added utility function for detaching from tracee. Updated names and removed ptrace::ptrace namespace

700: Get rid of a lot of transmutes r=asomers
Most could be replaced by simple raw pointer casts (or even perfectly
safe coercions!).

701: Calculate `nfds` parameter for `select` r=asomers
Doing this behind the scenes makes the API less error-prone and easier
to use. It should also fix my issue in https://github.com/nix-rust/nix/issues/679#issuecomment-316838148
