03:54 DemiMarie: Will compositors generally support linear modifiers?
03:59 YaLTeR[m]: Demi: I guess depends on the GPU and its driver. E.g. if I'm not mistaken, Nvidia cannot render into linear buffers
03:59 DemiMarie: YaLTeR: can it _accept_ linear buffers?
03:59 YaLTeR[m]: Probably
04:00 DemiMarie: Without linear buffers, my other options are to either copy to CPU memory or write a validation library that knows about every modifier I need to care about.
04:01 YaLTeR[m]: pretty sure compositors get supported modifier lists directly from the GPU drivers
04:01 DemiMarie: I am starting to suspect that this is a security vulnerability in most compositors out there.
04:02 DemiMarie: Which is more practical: writing a validation library or sending patches to use robust access to imported buffers?
04:02 DemiMarie:wonders if this should be a generic ioctl on dmabuf FDs
06:39 daniels: what?
06:40 daniels: Mesa generally validates for size on import
16:59 vyivel: i saw something about a new w-p release a few days ago; could https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/294 make it in too?
