Priority: medium Bug ID: 71282 Assignee: dri-devel at lists.freedesktop.org Summary: Cannot authenticate second libva client Severity: normal Classification: Unclassified OS: Linux (All) Reporter: rekjanov at epiphan.com Hardware: x86-64 (AMD64) Status: NEW Version: unspecified Component: General Product: DRI Created attachment 88733 --> https://bugs.freedesktop.org/attachment.cgi?id=88733&action=edit Test program Environment: * ubuntu 12.04.3 LTS with 3.8 kernel * No X11, pure DRM * libva 0.34 * libdrm 2.4.43 * regular user account, no CAP_SYS_ADMIN, but in 'video' group * A simple program, which calls vaInitialize and then sleeps for several seconds. * Intel video hardware (Ivy Bridge) Problem: If another test program instance is started while the first is sleeping, it fails in va_getDriverName. Debugging and source review shows that the first instance is authenticated automatically, because it gets the master. Second instance tries to authenticate using authmagic, but fails because auth magic ioctl is marked as DRM_AUTH - so you need to be already authenticated in order to authenticate! -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
