[Intel-gfx] [PATCH v6 0/4] drm: address potential UAF bugs with drm_master ptrs

[Desmond Cheong Zhi Xi]

This patch series addresses potential use-after-free errors when dereferencing pointers to struct drm_master. These were identified after one such bug was caught by Syzbot in drm_getunique():
https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803

The series is broken up into four patches:

1. Move a call to drm_is_current_master() out from a section locked by &dev->mode_config.mutex in drm_mode_getconnector(). This patch does not apply to stable.

2. Move a call to _drm_lease_held() out from the section locked by &dev->mode_config.idr_mutex in __drm_mode_object_find().

3. Implement a locked version of drm_is_current_master() function that's used within drm_auth.c.

4. Identify areas in drm_lease.c where pointers to struct drm_master are dereferenced, and ensure that the master pointers are not freed during use.

Changes in v5 -> v6:
- Patch 2:
Add patch 2 to the series. This patch moves the call to _drm_lease_held out from the section locked by &dev->mode_config.idr_mutex in __drm_mode_object_find.

- Patch 4:
Clarify the kerneldoc for dereferencing drm_file.master, as suggested by Daniel Vetter.

Refactor error paths with goto labels so that each function only has a single drm_master_put(), as suggested by Emil Velikov.

Modify comparison to NULL into "!master", as suggested by the intel-gfx CI.

Changes in v4 -> v5:
- Patch 1:
Add patch 1 to the series. The changes in patch 1 do not apply to stable because they apply to new changes in the drm-misc-next branch. This patch moves the call to drm_is_current_master in drm_mode_getconnector out from the section locked by &dev->mode_config.mutex.

Additionally, added a missing semicolon to the patch, caught by the intel-gfx CI.

- Patch 3:
Move changes to drm_connector.c into patch 1.

Changes in v3 -> v4:
- Patch 3:
Move the call to drm_is_current_master in drm_mode_getconnector out from the section locked by &dev->mode_config.mutex. As suggested by Daniel Vetter. This avoids a circular lock lock dependency as reported here https://patchwork.freedesktop.org/patch/440406/

Additionally, inside drm_is_current_master, instead of grabbing &fpriv->master->dev->master_mutex, we grab &fpriv->minor->dev->master_mutex to avoid dereferencing a null ptr if fpriv->master is not set.

- Patch 4:
Modify kerneldoc formatting.

Additionally, add a file_priv->master NULL check inside drm_file_get_master, and handle the NULL result accordingly in drm_lease.c. As suggested by Daniel Vetter.

Changes in v2 -> v3:
- Patch 3:
Move the definition of drm_is_current_master and the _locked version higher up in drm_auth.c to avoid needing a forward declaration of drm_is_current_master_locked. As suggested by Daniel Vetter.

- Patch 4:
Instead of leaking drm_device.master_mutex into drm_lease.c to protect drm_master pointers, add a new drm_file_get_master() function that returns drm_file->master while increasing its reference count, to prevent drm_file->master from being freed. As suggested by Daniel Vetter.

Changes in v1 -> v2:
- Patch 4:
Move the lock and assignment before the DRM_DEBUG_LEASE in drm_mode_get_lease_ioctl, as suggested by Emil Velikov.

[Intel-gfx] [PATCH v6 1/4] drm: avoid circular locks in drm_mode_getconnector

[Desmond Cheong Zhi Xi]

In preparation for a future patch to take a lock on
drm_device.master_mutex inside drm_is_current_master(), we first move
the call to drm_is_current_master() in drm_mode_getconnector out from the
section locked by &dev->mode_config.mutex. This avoids creating a
circular lock dependency.

Failing to avoid this lock dependency produces the following lockdep
splat:

[Intel-gfx] [PATCH v6 2/4] drm: avoid circular locks in __drm_mode_object_find

[Desmond Cheong Zhi Xi]

In a future patch, _drm_lease_held will dereference drm_file->master
only after making a call to drm_file_get_master which increments the
reference count of drm_file->master while holding a lock on
drm_device.master_mutex.

In preparation for this, the call to _drm_lease_held should be moved
out from the section locked by &dev->mode_config.idr_mutex. This
avoids inverting the lock hierarchy for
&dev->master_mutex --> &dev->mode_config.idr_mutex

[Intel-gfx] [PATCH v6 3/4] drm: add a locked version of drm_is_current_master

[Desmond Cheong Zhi Xi]

While checking the master status of the DRM file in
drm_is_current_master(), the device's master mutex should be
held. Without the mutex, the pointer fpriv->master may be freed
concurrently by another process calling drm_setmaster_ioctl(). This
could lead to use-after-free errors when the pointer is subsequently
dereferenced in drm_lease_owner().

The callers of drm_is_current_master() from drm_auth.c hold the
device's master mutex, but external callers do not. Hence, we implement
drm_is_current_master_locked() to be used within drm_auth.c, and
modify drm_is_current_master() to grab the device's master mutex
before checking the master status.

[Intel-gfx] [PATCH v6 4/4] drm: protect drm_master pointers in drm_lease.c

[Desmond Cheong Zhi Xi]

Currently, direct copies of drm_file->master pointers should be
protected by drm_device.master_mutex when being dereferenced. This is
because drm_file->master is not invariant for the lifetime of
drm_file. If drm_file is not the creator of master, then
drm_file->is_master is false, and a call to drm_setmaster_ioctl will
invoke drm_new_set_master, which then allocates a new master for
drm_file and puts the old master.

Thus, without holding drm_device.master_mutex, the old value of
drm_file->master could be freed while it is being used by another
concurrent process.

In drm_lease.c, there are multiple instances where drm_file->master is
accessed and dereferenced while drm_device.master_mutex is not
held. This makes drm_lease.c vulnerable to use-after-free bugs.

We address this issue in 3 ways:

1. Clarify in the kerneldoc that drm_file->master is protected by
drm_device.master_mutex.

2. Add a new drm_file_get_master() function that calls drm_master_get
on drm_file->master while holding on to drm_device.master_mutex. Since
drm_master_get increments the reference count of master, this
prevents master from being freed until we unreference it with
drm_master_put.

3. In each case where drm_file->master is directly accessed and
eventually dereferenced in drm_lease.c, we wrap the access in a call
to the new drm_file_get_master function, then unreference the master
pointer once we are done using it.
