Hi, I have filed an Ubuntu bug after being unable to use --db-attach=yes feature of valgrind. https://bugs.launchpad.net/bugs/665850
It looks like this feature has been destroyed "by design": https://wiki.ubuntu.com/Security/Features#ptrace https://wiki.ubuntu.com/SecurityTeam/Roadmap/KernelHardening#ptrace%20Protection This new hardened behaviour can be deactivated by modifying /proc/sys/kernel/yama/ptrace_scope which is then global and not really pretty solution. Does anybody have suggestion how to fix the problem in user space? I can easily imagine scenario where I would need to use valgrind with debugger on a machine, where I have no root access.
