Hi Greg,

With 4.11 the enlightenment window mangers fails to start setuid children due to commit 64b875f7ac8a ("ptrace: Capture the ptracer's creds not PT_PTRACE_CAP").

Commit c70d9d809fde ("ptrace: Properly initialize ptracer_cred on fork") in Linus tree fixes the issue. Tested with v4.11.4. Please consider cherry-picking.

Thanks
Ralph

Sorry for the delay, others also asked for this, I'll try to get to it for the next release.
