1083: Allow signal injection in ptrace::syscall and ptrace::detach r=asomers a=frangio Fixes #1049 Should I add tests for this functionality? By the way, I noticed that the BSD module doesn't have `ptrace::syscall`. I couldn't find a reason behind this in #949. Should we add it? Co-authored-by: Francisco Giordano <frangio.1@gmail.com>

1148: Implement sched::sched_getaffinity() r=asomers a=thib-ack Hello, I found the function `sched::sched_setaffinity()` but I also needed to get the process affinity and I did not find the function `sched::sched_getaffinity()` So I added the function which maps [sched_getaffinity(2)](https://linux.die.net/man/2/sched_getaffinity) which "get a process's CPU affinity mask" to the sched.rs file. I hope the code match your guidelines (returned `Result<CpuSet>` instead of pointer parameter) If that's not the case, tell me, I will fix asap. I hope this will help ! Thanks, Thibaut Co-authored-by: Thibaut Ackermann <thibaut@ackermann.dev>

1138: Add Signal::as_str() to get representation as static string r=asomers a=MikailBag # Motivation Currently string representation of signal can be obtained with AsRef<str> impl. But it has downside: returned string's lifetime is bound to lifetime of signal, so &str must be converted to String. This allocation is avoidable, because as_ref() only returns static strings. To fix this problem, my PR adds Signal::as_str() method, which returns static string. Co-authored-by: Mikail Bagishov <bagishov.mikail@yandex.ru>

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/

process_vm_readv requires it, and I'm not exactly sure which other things do too.
