Public bug reported: As part of the error reporting features in 12.10, we're adding the ability to generate reports from hanging applications. This requires that we can gdb attach and backtrace to an arbitrary PID running as the same user, which requires working around the restrictions set by the ptrace scope:
https://wiki.ubuntu.com/Security/Features#ptrace A new plugin for compiz will be written to notify a new dbus service on the system bus that it should write a gdb backtrace for the pid (provided by the _NET_WM_PID xprop. This service will only accept connections from the compiz process. It will only accept the request if the PID was running with a valid session cookie (unless this is overkill?). How does that sound? ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006398 Title: Bypassing ptrace restrictions for errors from hanging applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1006398/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
