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
Most of the EventFlags have been renamed already, but Poll was the only one remaining. This commit fixes that. Issue 317 https://github.com/nix-rust/nix/issues/317

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.

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.

This patch adds a wrapper for the acct(2) syscall, with two functions for enabling and disabling process accounting.
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.

This also adds a test for truncate (obviously) but, while doing so, also adds a test for the already-existing ftruncate.

2018-09-03new dir moduleScott Lamb
This is a lower-level interface than `std::fs::ReadDir`. Notable differences: * can be opened from a file descriptor (as returned by `openat`, perhaps before knowing if the path represents a file or directory). Uses `fdopendir` for this, available on all Unix platforms as of rust-lang/libc#1018. * implements `AsRawFd`, so it can be passed to `fstat`, `openat`, etc. * can be iterated through multiple times without closing and reopening the file descriptor. Each iteration rewinds when finished. * returns entries for `.` (current directory) and `..` (parent directory). * returns entries' names as a `CStr` (no allocation or conversion beyond whatever libc does).

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.
