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.

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

2019-08-22fix readlink/readlinkat to return too long only when it is longSendil Kumar
2019-07-17Add renameatScott Lamb
renameat is (somewhat oddly, imho) in stdio.h. I put it in nix::fcntl because there's no nix::stdio and all its friends (including the AT_* constants) are in nix::fcntl.

1058: Implement unlinkat r=asomers a=jlb6740 This adds the unlinkat function, which is part of POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/functions/unlinkat.html and widely implmented on Unix-family platforms. Co-authored-by: Johnnie Birch <45402135+jlb6740@users.noreply.github.com>
2019-07-14Implement unlinkatJohnnie Birch
This adds the unlinkat function, which is part of POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/functions/unlinkat.html and widely implmented on Unix-family platforms. Implement unlinkat - Update comments to unlink at and breakup tests Changes made based on comments from pull request #1058 Implement unlinkat - Update should_panic for more precise check Updae should_panic attribute for more precise check. Also remove some dead code and note the pull request ID. Implement unlinkat - Update error handling to use unwrap_err The previous patch failed testing on two targets that returned EPERM as the Sys error instead of EISDIR. This patch changes from using the should_panic attribute to using the unwrap_err and matching against the result. Implement Unlinkat - Passing tests should not print anything. Fix. Implement unlinkat - Update location of commit comment in the CHANGELOG Implement unlinkat - Remove newline

This fixes the tests on Rust 1.38.0. We'll fix them for real after release 0.15.0. Issue #1096
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

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 some bugs with multithreaded tests:Alan Somers
* kmod tests must run exclusively, because they load and unload a module with a constant name. * A few tests were doing some variant of chdir, but weren't taking the CWD_MTX. * The kmod tests read files by path relative to CWD, so they need the CWD_MTX. But they don't need it exclusively, so convert the CWD_MTX into an RwLock. * Tests that do change the cwd need to change it back when they're done.
2019-06-06Fix multiple problems with the test_acct testAlan Somers
* On Linux, it requires the CAP_SYS_PACCT capability. * Reenable the test on FreeBSD, because our FreeBSD CI environment is no longer jailed (since we switched from BuildBot to CirrusCI), but check at runtime whether the process is jailed. * test_acct needs the FORK_MTX because it uses Command::new . * Fix a race condition. acct(2) isn't synchronous. It starts a kernel thread but does not wait for it to become ready. Fix it by running the test command within the polling loop.
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.
2019-02-12`PollFd` event flags renamed to `PollFlags` from `EventFlags`.Amanjeev Sethi

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.

2018-11-27Merge #967bors[bot]
967: Add a wrapper for lutimes(2) r=asomers a=jmmv PR #944 added wrappers for the more-modern futimens(2) and utimesat(2), but unfortunately these APIs are not available on old-ish systems. In particular, macOS Sierra and below don't implement them, making the new APIs unusable. Whether we should care about such "old" systems is debatable, but the problem is that, at the moment, this is the only macOS version usable on Travis to test kexts and, thus, to test FUSE file systems. This should have been part of PR #946, which added a wrapper for utimes(2) following this same rationale, but missed lutimes(2) because I simply didn't notice it existed.
