Hi Folks,
I wanted to use strace(1) to get to the bottom of the glance service launch failures that have been plaguing Smokestack and Jenkins in the past few weeks: https://review.openstack.org/8722 However I just realized that Ubuntu from Maverick onward no longer allows ptrace to attach to a user's own processes that are not direct children :( So I'm wondering whether the CI side-of-the-house would be prepared to enable this temporarily on the Jenkins slaves, by running: echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope prior to the glance tests being kicked off, then reverting straight after. Or, for a more permanent setting: sed -e 's/kernel\.yama.\ptrace_scope *= *1/kernel.yama.ptrace_scope = 0/' /etc/sysctl.d/10-ptrace.conf and then re-cast the image used for the Jenkins slaves. Thanks, Eoghan _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
