Re: [libvirt] [PATCH] LXC: Fix virLXCControllerSetupDevPTS() wrt user namespaces

-----Original Message----- From: libvir-list-bounces(a)redhat.com [mailto:libvir-list-bounces@redhat.com] On Behalf Of Richard Weinberger Sent: Tuesday, July 29, 2014 4:59 AM To: libvir-list(a)redhat.com Cc: Richard Weinberger; david(a)sigma-star.at Subject: [libvirt] [PATCH] LXC: Fix virLXCControllerSetupDevPTS() wrt user namespaces The gid value passed to devpts has to be translated by hand as virLXCControllerSetupDevPTS() is called before setting up the user and group mappings. Otherwise devpts will use an unmapped gid and openpty() will fail within containers. Linux commit commit 23adbe12 ("fs,userns: Change inode_capable to capable_wrt_inode_uidgid") uncovered that issue.
