Summary0013265: PTRACE_GETEVENTMSG broken for pids in pidnamespaces
DescriptionIf you fork a child, which unshares CLONE_NEWPID, ptrace-attach to it, set PTRACE_O_TRACEFORK, then have the child fork, the ptrace eventmsg you receive will be the pid in the child's namespace, not yours. This is fixed by commit 4e52365f279564cef0ddd41db5237f0471381093 from 2014 which applies cleanly to the 3.10 kernel.

It was suggested on irc that i might ask for toracat to cherrypick the patch into the centosplus kernel,
Steps To ReproduceI can provide a test program, but the above desribes how to do it.
