* drm/vmwgfx: Convert macro to octal representationØyvind A. Holm2017-04-211-1/+1

This change should be part of commit 50f837371dd9 ("drm/vmwgfx: Revert "drm/vmwgfx: Replace numeric parameter like 0444 with macro""), but the patch was truncated somewhere in the patch route, so add the missing change.

| * dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macroLogan Gunthorpe2017-04-201-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Seeing the kunmap_atomic dma_buf_ops share the same name with a macro in highmem.h, the former can be aliased if any dma-buf user includes that header. I'm personally trying to include highmem.h inside scatterlist.h and this breaks the dma-buf code proper. Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP. To maintain consistency I've renamed all four of kmap* and kunmap* to be map* and unmap*. (Even though only kmap_atomic presently conflicts.)

Probably much better to look into refactoring the entire code to use the helpers, but since that's not a viable long-term solution fix the issue by open-coding a vmwgfx version of set_config, that does the legacy backoff dance internally. Note: Just compile-tested. The idea is to take drm_mode_set_config_internal(), remove the "is this a legacy driver" check, and whack the drm_atomic_legacy_backoff trickery at the end. Since drm_atomic_legacy_backoff is for atomic commits only we need to open-code it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Atomic helpers really want this instead of the hacked-up legacy backoff trick, which unfortunately prevents drivers from using their own private drm_modeset_locks. Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which don't yet use the new atomic color mgmt/gamma table stuff. Would be nice if they could switch over and just hook up drm_atomic_helper_legacy_gamma_set() instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In vmw_surface_define_ioctl(), the 'num_sizes' is the sum of the 'req->mip_levels' array. This array can be assigned any value from the user space. As both the 'num_sizes' and the array is uint32_t, it is easy to make 'num_sizes' overflow. The later 'mip_levels' is used as the loop count. This can lead an oob write. Add the check of 'req->mip_levels' to avoid this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, when a surface was opened using a legacy (non prime) handle, it was verified to have been created by a client in the same master realm. Relax this so that opening is also allowed recursively if the client already has the surface open. This works around a regression in svga mesa where opening of a shared surface is used recursively to obtain surface information.

* | drm/vmwgfx: Work around drm removal of control nodesThomas Hellstrom2017-02-262-3/+12
|/ | | | | | | | | | | | | | | | | | vmware tools has a daemon that gets layout information from the GUI and forwards it to DRM so that the modesetting code can set preferred connector locations and modes. This daemon was using control nodes but since control nodes were just removed, make it possible for the daemon to use render- or primary nodes instead. This is a bit ugly but will allow drm to proceed with removal of the mostly unused control-node code and allow vmware to proceed with fixing up automatic layout settings for gnome-shell/wayland. We bump minor to inform user-space about the api change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drm_mm range manager claimed to support top-down insertion, but it was neither searching for the top-most hole that could fit the allocation request nor fitting the request to the hole correctly. In order to search the range efficiently, we create a secondary index for the holes using either their size or their address. This index allows us to find the smallest hole or the hole at the bottom or top of the range efficiently, whilst keeping the hole stack to rapidly service evictions. v2: Search for holes both high and low. Rename flags to mode. v3: Discover rb_entry_safe() and use it! v4: Kerneldoc for enum drm_mm_insert_mode.
