2023-10-24net: ethernet: davinci_emac: Use MAC Address from Device TreeAdam Ford
Currently there is a device tree entry called "local-mac-address" which can be filled by the bootloader or manually set.This is useful when the user does not want to use the MAC address programmed into the SoC. Currently, the davinci_emac reads the MAC from the DT, copies it from pdata->mac_addr to priv->mac_addr, then blindly overwrites it by reading from registers in the SoC, and falls back to a random MAC if it's still not valid. This completely ignores any MAC address in the device tree. In order to use the local-mac-address, check to see if the contents of priv->mac_addr are valid before falling back to reading from the SoC when the MAC address is not valid.

2023-10-24sock: Ignore memcg pressure heuristics when raising allocatedAbel Wu
Before sockets became aware of net-memcg's memory pressure since commit e1aab161e013 ("socket: initial cgroup code."), the memory usage would be granted to raise if below average even when under protocol's pressure. This provides fairness among the sockets of same protocol. That commit changes this because the heuristic will also be effective when only memcg is under pressure which makes no sense. So revert that behavior. After reverting, __sk_mem_raise_allocated() no longer considers memcg's pressure. As memcgs are isolated from each other w.r.t. memory accounting, consuming one's budget won't affect others. So except the places where buffer sizes are needed to be tuned, allow workloads to use the memory they are provisioned.

2023-10-24net: microchip: lan743x: improve throughput with rx timestamp configVishvambar Panth S
Currently all RX frames are timestamped which results in a performance penalty when timestamping is not needed. The default is now being changed to not timestamp any Rx frames (HWTSTAMP_FILTER_NONE), but support has been added to allow changing the desired RX timestamping mode (HWTSTAMP_FILTER_ALL - which was the previous setting and HWTSTAMP_FILTER_PTP_V2_EVENT are now supported) using SIOCSHWTSTAMP. All settings were tested using the hwstamp_ctl application. It is also noted that ptp4l, when started, preconfigures the device to timestamp using HWTSTAMP_FILTER_PTP_V2_EVENT, so this driver continues to work properly "out of the box".

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>

2023-10-23page_pool: introduce page_pool_alloc() APIYunsheng Lin
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>

2023-10-23page_pool: unify frag_count handling in page_pool_is_last_frag()Yunsheng Lin
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>

2023-10-23Bluetooth: Fix double free in hci_conn_cleanupZhengHan Wang
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.

2023-10-23Bluetooth: msft: __hci_cmd_sync() doesn't return NULLDan Carpenter
The __hci_cmd_sync() function doesn't return NULL. Checking for NULL doesn't make the code safer, it just confuses people. When a function returns both error pointers and NULL then generally the NULL is a kind of success case. For example, maybe we look up an item then errors mean we ran out of memory but NULL means the item is not found. Or if we request a feature, then error pointers mean that there was an error but NULL means that the feature has been deliberately turned off. In this code it's different. The NULL is handled as if there is a bug in __hci_cmd_sync() where it accidentally returns NULL instead of a proper error code. This was done consistently until commit 9e14606d8f38 ("Bluetooth: msft: Extended monitor tracking by address filter") which deleted the work around for the potential future bug and treated NULL as success. Predicting potential future bugs is complicated, but we should just fix them instead of working around them. Instead of debating whether NULL is failure or success, let's just say it's currently impossible and delete the dead code.

2023-10-23Bluetooth: ISO: Pass BIG encryption info through QoSIulia Tanasescu
This enables a broadcast sink to be informed if the PA it has synced with is associated with an encrypted BIG, by retrieving the socket QoS and checking the encryption field. After PA sync has been successfully established and the first BIGInfo advertising report is received, a new hcon is added and notified to the ISO layer. The ISO layer sets the encryption field of the socket and hcon QoS according to the encryption parameter of the BIGInfo advertising report event. After that, the userspace is woken up, and the QoS of the new PA sync socket can be read, to inspect the encryption field and follow up accordingly.
