Todd Fiala f183754779 Fix HelloWorld attach test for Linux kernels with ptrace ancestor lockdown. ... Similar to a recent test I fixed for gdb-remote attach scenarios, this fix is for Linux kernels, such as Ubuntu's stock setup on 11.04-ish and later, where ptrace starts requiring a ptracer to be an ancestor of the inferior to be ptraced. This change checks for Linux and the ptrace-related flags. If they're found, it tries to switch on the "allow any ptracer" mode for the inferior as the first statements in the program. It's a best-effort solution - if the prctl call fails, the failure is ignored, and probably will lead to the test failing. The ptrace security behavior can be modified system-wide, but is outside the scope of the test to address. Hence I went with this particular solution. llvm-svn: 220650		2014-10-26 21:37:46 +00:00
