The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

The kzalloc() in brcmf_pcie_download_fw_nvram() will return null if the physical memory has run out. As a result, if we use get_random_bytes() to generate random bytes in the randbuf, the null pointer dereference bug will happen. In order to prevent allocation failure, this patch adds a separate function using buffer on kernel stack to generate random bytes in the randbuf, which could prevent the kernel stack from overflow. Fixes: 91918ce8 ("wifi: brcmfmac: pcie: Provide a buffer of random bytes to the device") Suggested-by:

The ssb_device_uevent() function first attempts to convert the 'dev' pointer to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before performing the NULL check, potentially leading to a NULL pointer dereference if 'dev' is NULL. To fix this issue, move the NULL check before dereferencing the 'dev' pointer, ensuring that the pointer is valid before attempting to use it.

We used EHT capability of 20MHz-only as rate mask to RA (rate adaptive) H2C command when connecting with AP set EHT 20MHz. It would get the wrong rate mask and the MCS rate can only reach MCS11. According to the description of 802.11be spec, if all supported channel bandwidth field of HE PHY capabilities are zero, then the EHT capability of 20MHz-only is valid. As a result, we adjust the code to set correct rate mask based on HE PHY bandwidth capability. Signed-off-by:

Patches were previously sent as part of a full feature series and were previously reviewed in that context: "Add support for QMC HDLC, framer infrastructure and PEF2256 framer" [1] In order to ease the merge, the full feature series has been split and needed parts were merged in v6.8-rc1: - "Prepare the PowerQUICC QMC and TSA for the HDLC QMC driver" [2] - "Add support for framer infrastructure and PEF2256 framer" [3] This series contains patches related to the QMC HDLC part (QMC HDLC driver): - Introduce the QMC HDLC driver (patches 1 and 2) - Add timeslots change support in QMC HDLC (patch 3) - Add framer support as a framer consumer in QMC HDLC (patch 4) Compare to the original full feature series, a modification was done on patch 3 in order to use a coherent prefix in the commit title. I kept the patches unsquashed as they were previously sent and reviewed. Of course, I can squash them if needed. Compared to the previous iteration: https://lore.kernel.org/linux-kernel/20240306080726.167338-1-herve.codina@bootlin.com/ this v7 series mainly: - Rename a variable. - Fix reverse xmas tree declarations. - Add 'Acked-by' tag. ==================== Signed-off-by:

Saeed Mahameed says: ==================== Support Multi-PF netdev (Socket Direct) This series adds support for combining multiple devices (PFs) of the same port under one netdev instance. Passing traffic through different devices belonging to different NUMA sockets saves cross-numa traffic and allows apps running on the same netdev from different numas to still feel a sense of proximity to the device and achieve improved performance. We achieve this by grouping PFs together, and creating the netdev only once all group members are probed. Symmetrically, we destroy the netdev once any of the PFs is removed. The channels are distributed between all devices, a proper configuration would utilize the correct close numa when working on a certain app/cpu. We pick one device to be a primary (leader), and it fills a special role. The other devices (secondaries) are disconnected from the network in the chip level (set to silent mode). All RX/TX traffic is steered through the primary to/from the secondaries. Currently, we limit the support to PFs only, and up to two devices (sockets). * tag 'mlx5-socket-direct-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: Documentation: networking: Add description for multi-pf netdev net/mlx5: Enable SD feature net/mlx5e: Block TLS device offload on combined SD netdev net/mlx5e: Support per-mdev queue counter net/mlx5e: Support cross-vhca RSS net/mlx5e: Let channels be SD-aware net/mlx5e: Create EN core HW resources for all secondary devices net/mlx5e: Create single netdev per SD group net/mlx5: SD, Add debugfs net/mlx5: SD, Add informative prints in kernel log net/mlx5: SD, Implement steering for primary and secondaries net/mlx5: SD, Implement devcom communication and primary election net/mlx5: SD, Implement basic query and instantiation net/mlx5: SD, Introduce SD lib net/mlx5: Add MPIR bit in mcam_access_reg ==================== Link: https://lore.kernel.org/r/20240307084229.500776-1-saeed@kernel.orgSigned-off-by:

The only error that can happen during a nexthop dump is insufficient space in the skb caring the netlink messages (EMSGSIZE). If this happens and some messages were already filled in, the nexthop code returns the skb length to signal the netlink core that more objects need to be dumped. After commit b5a89915 ("netlink: handle EMSGSIZE errors in the core") there is no need to handle this error in the nexthop code as it is now handled in the core. Simplify the code and simply return the error to the core. No regressions in nexthop tests: # ./fib_nexthops.sh Tests passed: 234 Tests failed: 0 Signed-off-by:

Similar to skb_unref(), add skb_data_unref() to save an expensive atomic operation (and cache line dirtying) when last reference on shinfo->dataref is released. I saw this opportunity on hosts with RAW sockets accidentally bound to UDP protocol, forcing an skb_clone() on all received packets. These RAW sockets had their receive queue full, so all clone packets were immediately dropped. When UDP recvmsg() consumes later the original skb, skb_release_data() is hitting atomic_sub_return() quite badly, because skb->clone has been set permanently. Note that this patch helps TCP TX performance, because TCP stack also use (fast) clones. This means that at least one of the two packets (the main skb or its clone) will no longer have to perform this atomic operation in skb_release_data(). Signed-off-by:

The hisilicon device now supports a new 200G link interface, which query from firmware in a new bit. Therefore, the HCLGE_SUPPORT_200G_R4_BIT capability bit has been added. The HCLGE_SUPPORT_200G_BIT has been renamed as HCLGE_SUPPORT_200G_R4_EXT_BIT, and the firmware has extended support for this mode.

Shannon Nelson says: ==================== ionic: putting ionic on a diet Building on the performance work done in the previous patchset [Link] https://lore.kernel.org/netdev/20240229193935.14197-1-shannon.nelson@amd.com/ this patchset puts the ionic driver on a diet, decreasing the memory requirements per queue, and simplifies a few more bits of logic. We trimmed the queue management structs and gained some ground, but the most savings came from trimming the individual buffer descriptors. The original design used a single generic buffer descriptor for Tx, Rx and Adminq needs, but the Rx and Adminq descriptors really don't need all the info that the Tx descriptors track. By splitting up the descriptor types we can significantly reduce the descriptor sizes for Rx and Adminq use. There is a small reduction in the queue management structs, saving about 3 cachelines per queuepair: ionic_qcq: Before: /* size: 2176, cachelines: 34, members: 23 */ After: /* size: 2048, cachelines: 32, members: 23 */ We also remove an array of completion descriptor pointers, or about 8 Kbytes per queue. But the biggest savings came from splitting the desc_info struct into queue specific structs and trimming out what was unnecessary. Before: ionic_desc_info: /* size: 496, cachelines: 8, members: 10 */ After: ionic_tx_desc_info: /* size: 496, cachelines: 8, members: 6 */ ionic_rx_desc_info: /* size: 224, cachelines: 4, members: 2 */ ionic_admin_desc_info: /* size: 8, cachelines: 1, members: 1 */ In a 64 core host the ionic driver will default to 64 queuepairs of 1024 descriptors for Rx, 1024 for Tx, and 80 for Adminq and Notifyq. The total memory usage for 64 queues: Before: 65 * sizeof(ionic_qcq) 141,440 + 64 * 1024 * sizeof(ionic_desc_info) 32,505,856 + 64 * 1024 * sizeof(ionic_desc_info) 32,505,856 + 64 * 1024 * 2 * sizeof(ionic_qc_info) 16,384 + 1 * 80 * sizeof(ionic_desc_info) 39,690 ---------- 65,201,038 After: 65 * sizeof(ionic_qcq) 133,120 + 64 * 1024 * sizeof(ionic_tx_desc_info) 32,505,856 + 64 * 1024 * sizeof(ionic_rx_desc_info) 14,680,064 + (removed) 0 + 1 * 80 * sizeof(ionic_admin desc_info) 640 ---------- 47,319,680 This saves us approximately 18 Mbytes per port in a 64 core machine, a 28% savings in our memory needs. In addition, this improves our simple single thread / single queue iperf case on a 9100 MTU connection from 86.7 to 95 Gbits/sec. ==================== Signed-off-by: -
