2023-10-24clk: cdce925: Extend match support for OF tablesBiju Das1-30/+35
The driver has an OF match table, still, it uses an ID lookup table for retrieving match data. Currently, the driver is working on the assumption that an I2C device registered via OF will always match a legacy I2C device ID. The correct approach is to have an OF device ID table using i2c_get_match_data() if the devices are registered via OF/ID. Unify the OF/ID table by using struct clk_cdce925_chip_info as match data for both these tables and replace the ID lookup table for the match data by i2c_get_match_data(). Split the array clk_cdce925_chip_info_tbl[] as individual variables, and make lines shorter by referring to e.g. &clk_cdce913_info instead of &clk_cdce925_chip_info_tbl[CDCE913]. Drop enum related to chip type as there is no user. While at it, remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing.

2023-10-24Merge branch 'introduce-page_pool_alloc-related-api'Jakub Kicinski12-58/+220
Yunsheng Lin says: ==================== introduce page_pool_alloc() related API In [1] & [2] & [3], there are usecases for veth and virtio_net to use frag support in page pool to reduce memory usage, and it may request different frag size depending on the head/tail room space for xdp_frame/shinfo and mtu/packet size. When the requested frag size is large enough that a single page can not be split into more than one frag, using frag support only have performance penalty because of the extra frag count handling for frag support. So this patchset provides a page pool API for the driver to allocate memory with least memory utilization and performance penalty when it doesn't know the size of memory it need beforehand. 1. https://patchwork.kernel.org/project/netdevbpf/patch/d3ae6bd3537fbce379382ac6a42f67e22f27ece2.1683896626.git.lorenzo@kernel.org/ 2. https://patchwork.kernel.org/project/netdevbpf/patch/20230526054621.18371-3-liangchen.linux@gmail.com/ 3. https://github.com/alobakin/linux/tree/iavf-pp-frag ==================== Link: https://lore.kernel.org/r/20231020095952.11055-1-linyunsheng@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-10-24page_pool: introduce page_pool_alloc() APIYunsheng Lin2-2/+68
Currently page pool supports the below use cases: use case 1: allocate page without page splitting using page_pool_alloc_pages() API if the driver knows that the memory it need is always bigger than half of the page allocated from page pool. use case 2: allocate page frag with page splitting using page_pool_alloc_frag() API if the driver knows that the memory it need is always smaller than or equal to the half of the page allocated from page pool. There is emerging use case [1] & [2] that is a mix of the above two case: the driver doesn't know the size of memory it need beforehand, so the driver may use something like below to allocate memory with least memory utilization and performance penalty: if (size << 1 > max_size) page = page_pool_alloc_pages(); else page = page_pool_alloc_frag(); To avoid the driver doing something like above, add the page_pool_alloc() API to support the above use case, and update the true size of memory that is acctually allocated by updating '*size' back to the driver in order to avoid exacerbating truesize underestimate problem. Rename page_pool_free() which is used in the destroy process to __page_pool_destroy() to avoid confusion with the newly added API. 1. https://lore.kernel.org/all/d3ae6bd3537fbce379382ac6a42f67e22f27ece2.1683896626.git.lorenzo@kernel.org/ 2. https://lore.kernel.org/all/20230526054621.18371-3-liangchen.linux@gmail.com/ Signed-off-by: Yunsheng Lin <linyunsheng@huawei.com> CC: Lorenzo Bianconi <lorenzo@kernel.org> CC: Alexander Duyck <alexander.duyck@gmail.com> CC: Liang Chen <liangchen.linux@gmail.com> CC: Alexander Lobakin <aleksander.lobakin@intel.com> Link: https://lore.kernel.org/r/20231020095952.11055-4-linyunsheng@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-10-24page_pool: unify frag_count handling in page_pool_is_last_frag()Yunsheng Lin2-14/+43
Currently when page_pool_create() is called with PP_FLAG_PAGE_FRAG flag, page_pool_alloc_pages() is only allowed to be called under the below constraints: 1. page_pool_fragment_page() need to be called to setup page->pp_frag_count immediately. 2. page_pool_defrag_page() often need to be called to drain the page->pp_frag_count when there is no more user will be holding on to that page. Those constraints exist in order to support a page to be split into multi fragments. And those constraints have some overhead because of the cache line dirtying/bouncing and atomic update. Those constraints are unavoidable for case when we need a page to be split into more than one fragment, but there is also case that we want to avoid the above constraints and their overhead when a page can't be split as it can only hold a fragment as requested by user, depending on different use cases: use case 1: allocate page without page splitting. use case 2: allocate page with page splitting. use case 3: allocate page with or without page splitting depending on the fragment size. Currently page pool only provide page_pool_alloc_pages() and page_pool_alloc_frag() API to enable the 1 & 2 separately, so we can not use a combination of 1 & 2 to enable 3, it is not possible yet because of the per page_pool flag PP_FLAG_PAGE_FRAG. So in order to allow allocating unsplit page without the overhead of split page while still allow allocating split page we need to remove the per page_pool flag in page_pool_is_last_frag(), as best as I can think of, it seems there are two methods as below: 1. Add per page flag/bit to indicate a page is split or not, which means we might need to update that flag/bit everytime the page is recycled, dirtying the cache line of 'struct page' for use case 1. 2. Unify the page->pp_frag_count handling for both split and unsplit page by assuming all pages in the page pool is split into a big fragment initially. As page pool already supports use case 1 without dirtying the cache line of 'struct page' whenever a page is recyclable, we need to support the above use case 3 with minimal overhead, especially not adding any noticeable overhead for use case 1, and we are already doing an optimization by not updating pp_frag_count in page_pool_defrag_page() for the last fragment user, this patch chooses to unify the pp_frag_count handling to support the above use case 3. There is no noticeable performance degradation and some justification for unifying the frag_count handling with this patch applied using a micro-benchmark testing in [1]. 1. https://lore.kernel.org/all/bf2591f8-7b3c-4480-bb2c-31dc9da1d6ac@huawei.com/ Signed-off-by: Yunsheng Lin <linyunsheng@huawei.com> CC: Lorenzo Bianconi <lorenzo@kernel.org> CC: Alexander Duyck <alexander.duyck@gmail.com> CC: Liang Chen <liangchen.linux@gmail.com> CC: Alexander Lobakin <aleksander.lobakin@intel.com> Link: https://lore.kernel.org/r/20231020095952.11055-2-linyunsheng@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-10-24KEYS: trusted: tee: Refactor register SHM usageSumit Garg1-44/+20
The OP-TEE driver using the old SMC based ABI permits overlapping shared buffers, but with the new FF-A based ABI each physical page may only be registered once. As the key and blob buffer are allocated adjancently, there is no need for redundant register shared memory invocation. Also, it is incompatibile with FF-A based ABI limitation. So refactor register shared memory implementation to use only single invocation to register both key and blob buffers.

Currently, split ops of doit and dumpit are merged into a single iter item when they are subsequent. However, there is no guarantee that the dumpit op is for the same cmd as doit op. Fix this by checking if cmd is the same for both. This problem does not occur in existing families.

In idpf_vc_core_init, the mailbox work is queued on a mailbox workqueue but it is not cancelled on error. This results in a call trace when idpf_mbx_task tries to access the freed mailbox queue pointer. Fix it by cancelling the mailbox work in the error path.

2023-10-24idpf: set scheduling mode for completion queueMichal Kubiak2-3/+15
The HW must be programmed differently for queue-based scheduling mode. To program the completion queue context correctly, the control plane must know the scheduling mode not only for the Tx queue, but also for the completion queue. Unfortunately, currently the driver sets the scheduling mode only for the Tx queues. Propagate the scheduling mode data for the completion queue as well when sending the queue configuration messages.

2023-10-23Bluetooth: Fix double free in hci_conn_cleanupZhengHan Wang2-15/+14
syzbot reports a slab use-after-free in hci_conn_hash_flush [1]. After releasing an object using hci_conn_del_sysfs in the hci_conn_cleanup function, releasing the same object again using the hci_dev_put and hci_conn_put functions causes a double free. Here's a simplified flow: hci_conn_del_sysfs: hci_dev_put put_device kobject_put kref_put kobject_release kobject_cleanup kfree_const kfree(name) hci_dev_put: ... kfree(name) hci_conn_put: put_device ... kfree(name) This patch drop the hci_dev_put and hci_conn_put function call in hci_conn_cleanup function, because the object is freed in hci_conn_del_sysfs function. This patch also fixes the refcounting in hci_conn_add_sysfs() and hci_conn_del_sysfs() to take into account device_add() failures. This fixes CVE-2023-28464.
