When built with Control Flow Integrity, function prototypes between caller and function declaration must match. These mismatches are visible at compile time with the new -Wcast-function-type-strict in Clang[1]. Of the 1549 warnings found, 188 come from the atmel driver. For example: drivers/net/wireless/atmel/atmel.c:2518:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, void *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict] (iw_handler) atmel_config_commit, /* SIOCSIWCOMMIT */ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The atmel Wireless Extension handler callbacks (iw_handler) use a union for the data argument. Actually use the union and perform explicit member selection in the function body instead of having a function prototype mismatch. There are no resulting binary differences. This patch is a cleanup based on Brad Spengler/PaX Team's modifications to the atmel driver in their last public patch of grsecurity/PaX based on my understanding of the code. Changes or omissions from the original code are mine and don't reflect the original grsecurity/PaX code.

MAC maintains TX FIFO to transmit packets with meta data to BB layer. To debug abnormal transmission, we need to dump the content to dig problem. Since FIFO of 8852C locates on different address with different size and need additional switch to enable read operation, this patch adds the changes accordingly. Signed-off-by:

Auto Channel Select feature of HostAP uses dump_survey to fetch OBSS statistics. When the device is in the middle of an authentication sequence or just at the end of authentication completion, running dump_survey would trigger a channel change. The channel change in-turn can cause packet loss, resulting in authentication delay. With this change, dump_survey won't be run when authentication or association is in progress, hence resolving the issue. Signed-off-by:

When doing dump_survey, host will call "dump_obss" iovar to firmware side. Host need to make sure the HW clock in dongle is on, or there is high probability that firmware gets trap because register or shared memory access failed. To fix this, we disable mpc when doing dump obss and set it back after that.

Re-enable the function rtl8xxxu_gen2_report_connect. It informs the firmware when connecting to a network. This makes the firmware enable the rate control, which makes the upload faster. It also informs the firmware when disconnecting from a network. In the past this made reconnecting impossible because it was sending the auth on queue 0x7 (TXDESC_QUEUE_VO) instead of queue 0x12 (TXDESC_QUEUE_MGNT): wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 1/3) wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 2/3) wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 3/3) wlp0s20f0u3: authentication with 90:55:de:__:__:__ timed out Probably the firmware disables the unnecessary TX queues when it knows it's disconnected. However, this was fixed in commit edd5747a ("wifi: rtl8xxxu: Fix skb misuse in TX queue selection").

This chip is found in the cheapest USB adapters, e.g. 1.17 USD with VAT and shipping from China included. It's a gen 2 chip, similar to the RTL8723BU, but without Bluetooth. Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps. The vendor driver rtl8188fu version 4.3.23.6_20964.20170110 [0] was used as reference. The CD shipped with the device includes a newer driver, version 5.11.5-1-g12f7cde4b.20201102, but that one couldn't complete the WPA2 key exchange thing for whatever reason.

Previously, we thought control registers or setting things for TX power series may change according to chip. So, setting functions are implemented chip by chip. However, until now, the functions keep the same among chips, at least 8852A, 8852C, and 8852B. There is a sufficient number of chips to share generic setting functions. So, we now remake them including TX power by rate, TX power offset, TX power limit, and TX power limit RU as generic ones in phy.c. Besides, there are some code refinements in the generic ones, but almost all of the logic doesn't change. Signed-off-by:

struct mlx5e_alloc_unit consists of a single union. Convert it to a union itself to simplify casting it to struct xdp_buff *, which will be used to implement XSK batching on striding RQ. Signed-off-by:
-
Maxim Mikityanskiy authored
mlx5e_alloc_unit stores the DMA address and a pointer to either struct page (regular RQ) or struct xdp_buff (XSK RQ). This DMA address is redundant, because when a page or an XSK frame is allocated, the same address is also stored there. Some flows take the address from struct mlx5e_alloc_unit, and some take it from struct page or xdp_buff. This commit removes the address from struct mlx5e_alloc_unit, which makes it twice as small and improves locality (this struct is used in an array), also saving on unnecessary stores to the addr field. Almost all flows know unambiguously whether the DMA address should be taken from page or from xdp_buff. The exception is the allocation flows, where a new branch appeared, which will be optimized out in the next commits. struct mlx5e_alloc_unit used to be called mlx5e_dma_info. Signed-off-by:

Maxim Mikityanskiy authored
The next commit will remove the DMA address from the struct currently called mlx5e_dma_info, because the same value can be retrieved with page_pool_get_dma_addr(page) in almost all cases, with the notable exception of SHAMPO (HW GRO implementation) that modifies this address on the fly, after the initial allocation. To keep the SHAMPO logic intact, struct mlx5e_dma_info remains in the SHAMPO code, consisting of addr and page (XSK is not compatible with SHAMPO). The struct used in all other places is renamed to mlx5e_alloc_unit, allowing the next commit to remove the addr field without affecting SHAMPO. The new name means "allocation unit", and it's more appropriate after the field with the DMA address gets removed. Signed-off-by:

RX page cache stores dma_info structs, that consist of a pointer to struct page and a DMA address. In fact, the DMA address is extracted from struct page using page_pool_get_dma_addr when a page is pushed to the cache. By moving this call to the point when a page is popped from the cache, we can avoid storing the DMA address in the cache, effectively reducing its size by two times without losing any functionality.

WQEs must not cross page boundaries, they are padded with NOPs if they don't fit the page. mlx5e_mpwrq_total_umr_wqebbs doesn't take into account this padding, risking reserving not enough space. The padding is not straightforward to add to this calculation, because WQEs of different sizes may be mixed together in the queue. If each page ends with a big WQE that doesn't fit and requires at most its size minus 1 WQEBB of padding, the total space can be much bigger than in case when smaller WQEs take advantage of this padding. Replace the wrong exact calculation by the following estimation. Each padding can be at most the size of the maximum WQE used in the queue minus one WQEBB. Let's call the rest of the page "useful space". If we divide the total size of all needed WQEs by this useful space, rounding up, we'll get the number of pages, which is enough to contain all these WQEs. It's correct, because every WQE that appeared on the boundary between two blocks of useful space would start in the useful space of one page and end in the padding of the same page, while our estimation reserved space for its tail in the next space, making the estimation not smaller than the real space occupied in the queue. The code actually uses a looser estimation: instead of taking the maximum size of all used WQE types minus 1 WQEBB, it takes the maximum hardware size of a WQE. It's made for simplicity and extensibility. Signed-off-by:
