This series fixes a use-after-free that can happen when importing a
dma-buf and dma_buf_dynamic_attach() fails.

The imported BO is created as ttm_bo_type_sg with bo->base.resv pointing
at the exporter's dma_buf->resv before the attach is attempted. If the
attach fails, the importer holds no attachment and no dma-buf reference,
yet the BO still points at the exporter's resv. Once the exporter is
freed, a later dma_resv_lock(bo->base.resv) can hit freed memory:

  Oops: general protection fault, probably for non-canonical address
        0x6b6b6b6b6b6b6b9c
  Workqueue: ttm ttm_bo_delayed_delete [ttm]
  RIP: 0010:mutex_can_spin_on_owner+0x3f/0xc0

There are two places where the stale resv can be reached:

Patch 1 fixes the TTM delayed-delete path. Failed sg imports now
individualize bo->base.resv to the private _resv, keyed on
import_attach, while successful imports keep the shared exporter resv for
normal dma-buf cleanup.

Patch 2 fixes the xe LRU-walker path raised during review. xe was
creating imported sg BOs with a ttm_resource before attach succeeded,
making them visible to LRU walkers. An LRU walker could then take a BO
reference and lock bo->base.resv before the TTM release path could
individualize it. xe now creates imported sg BOs with empty initial
placement, keeping bo->resource NULL and off the LRU until after a
successful attach.

v5:
 - Add drm/xe patch to keep imported sg BOs off the LRU before attach
   succeeds; the TTM fix alone is not sufficient for xe if the BO is
   already LRU-visible. (Thomas)
   v4 patch:
   https://patchwork.freedesktop.org/patch/736663/?series=169129&rev=2
  - Patch 1 (drm/ttm) carries Christian's Reviewed-by from v4.

v4:
 - Moved import_attach check to after dma_resv_copy_fences() so fences
   are copied before returning for successful imports (Thomas).
 - Removed exporter-alive claim from commit message (Thomas).

v3:
 - Dropped the xe-side reordering approach since importer_priv must be
   valid when dma_buf_dynamic_attach() publishes the attachment.
 - Per Christian's suggestion on the v1 thread, keyed the check on
   import_attach rather than removing the sg guard entirely.
 - Fixes both xe and amdgpu in a single TTM patch.

  drm/xe: Keep imported sg BOs off LRU until dma-buf attach succeeds

When a dma-buf importer creates a ttm_bo_type_sg BO with bo->base.resv
pointing at the exporter's dma_buf->resv and dma_buf_dynamic_attach()
fails, no dma_buf reference is held. The exporter can be freed before
the delayed_delete worker calls dma_resv_lock(bo->base.resv), causing a
use-after-free:

  Oops: general protection fault, probably for non-canonical address
        0x6b6b6b6b6b6b6b9c
  Workqueue: ttm ttm_bo_delayed_delete [ttm]
  RIP: 0010:mutex_can_spin_on_owner+0x3f/0xc0

ttm_bo_individualize_resv() skips the resv swap for all sg BOs to keep
the shared resv available for delayed_delete to release the dma-buf
mapping. A BO whose attach never succeeded has no mapping to release,
yet it keeps bo->base.resv pointing at the exporter resv that
delayed_delete later locks once the exporter is gone.

Fix this by checking bo->base.import_attach, which is set only after a
successful attach. The check is placed after dma_resv_copy_fences() so
successful imports still copy fences to _resv before returning, keeping
the shared resv for delayed_delete. Failed imports fall through to swap
resv to _resv, so delayed_delete never locks the stale exporter resv.

Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/work_items/8023

It seems you dropped the patch changelog?

Also the WARN_ON_ONCE() we discussed for last version?

Sorry about both.
I had added the changelog in the cover letter only; I'll add it below the --- in the patch as well.

Also, I should have kept it. Will add it back: WARN_ON_ONCE(bo->type == ttm_bo_type_sg && bo->resource);

With the xe patch (patch 2)applied, this should not hit for xe anymore, but yes it will help to catch other driver that makes a failed sg import LRU-visible before attach succeeds.
I will update this in v6.

Thank you,
Nitin

Imported dma-buf BOs are created as ttm_bo_type_sg with bo->base.resv
pointing at the exporter's resv. They are initialized with system
placement, which allocates a ttm_resource and makes the BO visible to
TTM LRU walkers before dma_buf_dynamic_attach() has succeeded.

If attach fails, xe holds no dma-buf reference, but an LRU walker may
already have referenced the BO and locked bo->base.resv (the exporter
resv). If the exporter is then freed, this is a use-after-free.

Use an empty initial placement for imported sg BOs so bo->resource
stays NULL and the BO is never added to an LRU before attach succeeds.

As a result sg BOs now start without a resource, so their first move
has old_mem == NULL. Check ttm_bo_type_sg before the creation path in
xe_bo_move() so imports always use the dma-buf move path, and handle
resource-less sg BOs in xe_evict_flags() before dereferencing
tbo->resource.

Better if evict is not called on them at all. Could we have the dma-buf
move_notify immediately return 0 if the bo has no resource?

Agreed, will add an early return in xe_dma_buf_move_notify() for !bo->ttm.resource.

Yes, will drop the xe_evict_flags() change.

However, CI showed another issue with the empty-placement (num_placement=0) approach, 
which seen only on BMG-VM devices and not reproduced on bare-metal BMG.

num_placement=0 keeps the BO off the LRU, but it can make ttm_bo_validate() go through ttm_bo_pipeline_gutting() and create a
transfer/ghost BO when the exporter resv has unsignaled fences. That object can outlive the exporter and we still hit the UAF in
dma_resv_copy_fences() from delayed_delete.

I'm further checking on this approach.

Hi,

Please drop this series - both patches:

  [PATCH v5 1/2] drm/ttm: Fix UAF on dma-buf attach failure for sg BOs
  [PATCH v5 2/2] drm/xe: Keep imported sg BOs off LRU until dma-buf
                 attach succeeds

These addressed the UAFs  (patch 1 the TTM delayed-delete path, 
patch 2 the xe LRU-walker path) and were getting increasingly complex. 
Patch 2 also regressed in CI BAT: the empty placement (num_placement=0) took the ttm_bo_pipeline_gutting() path,
which creates a ghost BO that outlives the exporter and hit the same UAF in dma_resv_copy_fences() during delayed delete.

Following Thomas' review and the approach he suggested (discussed offline), we're going with
a simpler root-cause fix in xe instead: hold a dma-buf reference for the
whole lifetime of the imported BO, so the shared resv can never be freed
while the BO still references it. This closes all the paths at once and
drops the need for the TTM change and the LRU/placement handling.

I'll send the replacement as a separate patch:
  drm/xe: Hold a dma-buf reference for imported Bos

Thank you,
Nitin
