2019-09-19Fix test breakage in Seccomp mode.Alan Somers
Travis is now using Seccomp, and Docker's default Seccomp policy disables execveat (though, weirdly, not fexecve). It also prohibits any operations on AF_ALG sockets. While I'm here, replace close/dup with dup2, which is more reliable. Also, drop the fork mutex earlier. This way all of the exeve tests will run, even if one fails. https://docs.docker.com/engine/security/seccomp/
2019-09-19Require CAP_SYS_PTRACE for certain testsAlan Somers
process_vm_readv requires it, and I'm not exactly sure which other things do too.

1120: Fix length of abstract socket address r=asomers a=yshui NULL bytes have no special significance in an abstrace address, and the length of the address is solely decided by the length member. If the length is set to sun_path.len(), all the NULL bytes will be considered part of the address. Tests are updated accordingly. Closes #1119 Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com> Co-authored-by: Yuxuan Shui <yshuiv7@gmail.com>

2019-09-04Replace Signal::from_c_int by Signal::try_fromAlan Somers
TryFrom wasn't stable when that function was written.
2019-09-03Skip the aio_suspend test on LinuxAlan Somers
On Travis (and only on Travis) this test crashes. It hits an internal assertion within glibc. It happens reliably with rustc 1.37.0. Ignore the test until Travis updates its images; then we'll try again. Issue #1099
2019-09-03Replace most instances of mem::uninitialized with mem::MaybeUninitAlan Somers
Only two instances remain: * For the deprecated sys::socket::CmsgSpace::new. We should probably just remove that method. * For sys::termios::Termios::default_uninit. This will require some more thought. Fixes #1096
2019-08-28Fix some ioctl tests on muslAlan Somers
Weirdly, musl uses i32 to store the ioctl opcode

1095: Fix warnings on Rust 1.37.0 r=asomers a=asomers * Replace obsolete range syntax "..." with inclusive range "..=" * Use dyn Trait syntax instead of Box<Trait> * Raise MSRV to 1.27.0 (for dyn Trait syntax) * Test with nightly again Co-authored-by: Alan Somers <asomers@gmail.com>
2019-07-13Fix warnings on Rust 1.37.0Alan Somers
* Replace obsolete range syntax "..." with inclusive range "..=" * Use dyn Trait syntax instead of Box<Trait> * Raise MSRV to 1.27.0 (for dyn Trait syntax) * Raise MSRV to 1.31.0 (because of rand) tempfile pulls in rand, and rand pulls in fuchsia-cprng, which requires 1.31.0. Why rand pulls in fuchsia-cprng I don't know. It's specified as a target-specific dependency, but Cargo tries to build it anyway (only on Linux, not on FreeBSD or OSX). A bug in Cargo 1.27.0?
2019-07-12test_socket: add AddressFamily::Vsock testStefano Garzarella
The current VSOCK implementation does not support loopback devices, so, for now, we expect a failure in the spawned thread when it tries to connect. Signed-off-by: Stefano Garzarella <sgarzare@redhat.com>
2019-06-11Fix tests for abstract socketsBryant Mairs
Abstract paths should always be N-1 in length where N is the length of the `sun_path` field (first byte is \0). Given that, `UnixAddr::new_abstract()` should always return this N-1 length, not just the length of the string provided (the rest of the array will be \0s).
2019-06-09Add extra traits for all typesBryant Mairs
Derive Clone, Copy, Eq, Hash, and PartialEq for all types. Not all traits are supported by all types, which is why many are missing some.
2019-06-06Fix an "unused use statement" warning on non-musl platformsAlan Somers
This was an oversight from 974320d09fbd1fae79da537383c2144ed9aa4967
2019-06-06Fix kmod tests on in Linux containersAlan Somers
It's not sufficient to check for root privileges, because a containerized process may have root's euid but still lack important capabilities. Fix these tests by checking for the CAP_SYS_MOD capability.
2019-06-06Fix the is_so_mark_functional test in Linux containersAlan Somers
It's not sufficient to check for root privileges. In a container, the euid may be root even though the user lacks some capabilities. Replace this test's root check with a check for the CAP_NET_ADMIN capability instead.
2019-06-02Fix test_pthread_self on muslAlan Somers
On musl, pthread_t is a pointer type.

2019-02-14Fix misaligned references when using recvmsg with control messagesAlan Somers
On some platforms the alignment of cmsg_data could be less than the alignment of the messages that it contains. That led to unaligned reads on those platforms. This change fixes the issue by always copying the message contents into aligned objects. The change is not 100% backwards compatible when using recvmsg. Users may have to replace code like this: ```rust if let ControlMessage::ScmRights(&fds) = cmsg { ``` with this: ```rust if let ControlMessageOwned::ScmRights(fds) = cmsg { ``` Fixes #999
2019-02-14Replace CmsgSpace with a macroAlan Somers
CmsgSpace had three problems: 1) It would oversize buffers that expect multiple control messages 2) It didn't use the libc CMSG_SPACE(3) macro, so it might actually undersize a buffer for a single control message. 3) It could do bad things on drop, if you instantiate it with a type that implements Drop (which none of the currently supported ControlMessage types do). Fixes #994
2019-02-14Fix error handling of RecvMsgAlan Somers
There were two problems: 1) It would always return Ok, even on error 2) It could panic if there was an error, because sockaddr_storage_to_addr would be called on uninitialized memory.
2019-01-23Add IP_RECVIF & IP_RECVDSTADDR.Tom Pusateri
Include IP_PKTINFO and IP6_PKTINFO on netbsd/openbsd.
2019-01-15Fix build and tests issues on OpenBSD 6.4+Andrei-Marius Radu
1) lutimes doesn't exist on OpenBSD so it needs to be under conditional compilation. The only "reference" that I could find related to this is the discussion here: https://github.com/rust-lang/libc/pull/790 . 2) fexecve doesn't exist on OpenBSD so add conditional compilation for it in unistd and in related tests. The only "reference" that I could find is a mention that fexecve is not implemented on OpenBSD in the manual pages for signal(3) and sigaction(2): Official repository (search for "fexecve"): https://cvsweb.openbsd.org/src/lib/libc/sys/sigaction.2?rev=1.75&content-type=text/x-cvsweb-markup Github mirror: https://github.com/openbsd/src/blob/master/lib/libc/sys/sigaction.2#L619 3) AIO doesn't work on OpenBSD so put test_aio_drop under conditional compilation. 4) Add relevant changelog entries. P.S. On OpenBSD remains the issue of test_scm_rights which builds correctly but fails at runtime.

2018-10-21Added ptrace support for BSDsxd009642
* Moved ptrace API into it's own module with cfg'ed modules exported for linux/android or BSDs. * Replicated current linux API for BSD * Added API functions to peek and poke memory to avoid needing to replicate deprecated linux API and remaining feature complete * Added helper function for `PTRACE_KILL` requests * Updated tests based on new API changes * Added addition kill calls to `test_ptrace_cont` as inferior death doesn't happen immediately on OSX which caused issues in the tests.

2018-06-01Remove tests that weren't mineBryant Mairs
2018-06-01Remove emulation of FD_CLOEXEC/O_NONBLOCKBryant Mairs
Rather than using the native implementation of these constants on supported platforms, the native implementation was instead emulated. This was also hidden from the user even though this could result in data races and the functionality being broken. Native functionality is, however, not support on macos/ios. Rather than enable this emulation solely for this platform, it should be removed as this is a dangerous abstraction.
2018-04-28select: add pselect syscallAndreas Fuchs
This is a straight port of @abbradar's work in #276, with two (somewhat weak) tests and a bit of documentation.
2018-04-10Implement equivalent for _IOWINT for FreeBSD-like targetsBryant Mairs
ioctls on FreeBSD and DragonflyBSD have a separate request code generation macro `_IOWINT` which is now exposed as `request_code_write_int`. `ioctl_write_int` is also fixed on these platforms to use this new request
2018-04-10Refactor the ioctl API and documentationBryant Mairs
* Split `ioctl!` into separate macros. This makes documentation easier to read. * For every `ioctl_*!` macro include a description of the macro arguments as, the function prototype for the generated wrapper function, and an example if we have one. * Expose `request_code_*!` in the documentation to make the `ioctl_*_bad` macros easier to use. * Reorganize the file hierarchy to be simpler
2018-04-06Add LioCb::listio_resubmitAlan Somers
It helps deal with errors like EAGAIN, which can result in a subset of an LioCb's operations being queued. The test is only enabled on FreeBSD, because it requires intimate knowledge of AIO system limits.
2018-03-22Replace AioCb::from_bytes with more generic from_boxed_sliceAlan Somers
Supporting the bytes crate was unnecessarily specific. This change replaces from_bytes and from_bytes_mut with from_boxed_slice and from_boxed_mut_slice, which can work with anything that implements Borrow<[u8]> and BorrowMut<[u8]>, respectively.
2018-03-22Change sys::aio::lio_listio to sys::aio::LioCb::listioAlan Somers
The new LioCb structure allows us to control the exact arguments passed to lio_listio, guaranteeing that each call gets a unique storage location for the list argument. This prevents clients from misusing lio_listio in a way that causes events to get dropped from a kqueue Fixes #870
