From 498595d54347d711dbd24247ed12c659b9d89c58 Mon Sep 17 00:00:00 2001 From: Michael Pratt Date: Mon, 9 Dec 2019 11:21:01 -0800 Subject: Add tests for rseq(2) Add a decent set of syscall tests for rseq(2). These are a bit awkward because of issues with library integration. libc may register rseq on thread start (including before main on the initial thread), precluding much testing. Thus we run tests in a libc-free subprocess. Support for rseq(2) in gVisor will come in a later commit.
