Vulnerability Title
vdpa/mlx5: Fix release of uninitialized resources on error path
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
vdpa/mlx5: Fix release of uninitialized resources on error path
The commit in the fixes tag made sure that mlx5_vdpa_free()
is the single entrypoint for removing the vdpa device resources
added in mlx5_vdpa_dev_add(), even in the cleanup path of
mlx5_vdpa_dev_add().
This means that all functions from mlx5_vdpa_free() should be able to
handle uninitialized resources. This was not the case though:
mlx5_vdpa_destroy_mr_resources() and mlx5_cmd_cleanup_async_ctx()
were not able to do so. This caused the splat below when adding
a vdpa device without a MAC address.
This patch fixes these remaining issues:
- Makes mlx5_vdpa_destroy_mr_resources() return early if called on
uninitialized resources.
- Moves mlx5_cmd_init_async_ctx() early on during device addition
because it can't fail. This means that mlx5_cmd_cleanup_async_ctx()
also can't fail. To mirror this, move the call site of
mlx5_cmd_cleanup_async_ctx() in mlx5_vdpa_free().
An additional comment was added in mlx5_vdpa_free() to document
the expectations of functions called from this context.
Splat:
mlx5_core 0000:b5:03.2: mlx5_vdpa_dev_add:3950:(pid 2306) warning: No mac address provisioned?
