Subject: [dpdk-dev] [PATCH] kni: Passing task_pid_vnr(current) to get_net_ns_by_pid() in kni_ioctl_create()
Date: Mon, 15 Jun 2015 00:07:33 -0400 [thread overview]
Message-ID: <1434341253-3227-1-git-send-email-liuwf@arraynetworks.com.cn> (raw)
In containers like docker, current->pid returns current process's global PID instead of its
own PID under containers's PID namespace, and get_net_ns_by_pid() suppose to accept a virtual
PID under its own namespace, so we should use task_pid_vnr(current) to get current process's
virtual PID instead of current->pid.
