Zenghui Yu d43fde5ebf kselftests: dmabuf-heaps: Ensure the driver name is null-terminated ... [ Upstream commit 291e4baf70 ] Even if a vgem device is configured in, we will skip the import_vgem_fd() test almost every time. TAP version 13 1..11 # Testing heap: system # ======================================= # Testing allocation and importing: ok 1 # SKIP Could not open vgem -1 The problem is that we use the DRM_IOCTL_VERSION ioctl to query the driver version information but leave the name field a non-null-terminated string. Terminate it properly to actually test against the vgem device. While at it, let's check the length of the driver name is exactly 4 bytes and return early otherwise (in case there is a name like "vgemfoo" that gets converted to "vgem\0" unexpectedly).
