  - xdp: fix invalid wait context of page_pool_destroy() If the driver uses a page pool, it creates a page     pool with page_pool_create(). The reference count of page pool is 1 as default. A page pool will be     destroyed only when a reference count reaches 0. page_pool_destroy() is used to destroy page pool, it     decreases a reference count. When a page pool is destroyed, ->disconnect() is called, which is     mem_allocator_disconnect(). This function internally acquires mutex_lock(). If the driver uses XDP, it     registers a memory model with xdp_rxq_info_reg_mem_model(). The xdp_rxq_info_reg_mem_model() internally     increases a page pool reference count if a memory model is a page pool. Now the reference count is 2. To     destroy a page pool, the driver should call both page_pool_destroy() and xdp_unreg_mem_model(). The     xdp_unreg_mem_model() internally calls page_pool_destroy(). Only page_pool_destroy() decreases a reference     count. If a driver calls page_pool_destroy() then xdp_unreg_mem_model(), we will face an invalid wait     context warning. Because xdp_unreg_mem_model() calls page_pool_destroy() with rcu_read_lock(). The     page_pool_destroy() internally acquires mutex_lock().

    Using xa without rcu_read_lock() here is safe. xa is freed by __xdp_mem_allocator_rcu_free() and this is     called by call_rcu() of mem_xa_remove(). The mem_xa_remove() is called by page_pool_destroy() if a     reference count reaches 0. The xa is already protected by the reference count mechanism well in the     control plane. So removing rcu_read_lock() for page_pool_destroy() is safe. (CVE-2024-43834)
