Since commit 2d47c6956ab3 ("ubsan: Tighten UBSAN_BOUNDS on GCC"), UBSAN_BOUNDS no longer pretends 1-element arrays are unbounded. Walking 'element' and 'channel_list' will trigger warnings, so make them proper flexible arrays.

2023-09-11wifi: iwlwifi: mvm: Fix a memory corruption issueChristophe JAILLET1-1/+1
A few lines above, space is kzalloc()'ed for: sizeof(struct iwl_nvm_data) + sizeof(struct ieee80211_channel) + sizeof(struct ieee80211_rate) 'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is fine. At the end of this structure, there is the 'channels' flex array. Each element is of type 'struct ieee80211_channel'. So only 1 element is allocated in this array. When doing: mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels; We point at the first element of the 'channels' flex array. So this is fine. However, when doing: mvm->nvm_data->bands[0].bitrates = (void *)((u8 *)mvm->nvm_data->channels + 1); because of the "(u8 *)" cast, we add only 1 to the address of the beginning of the flex array. It is likely that we want point at the 'struct ieee80211_rate' allocated just after. Remove the spurious casting so that the pointer arithmetic works as expected.

2023-09-04wifi: mwifiex: Fix tlv_buf_left calculationGustavo A. R. Silva1-2/+2
In a TLV encoding scheme, the Length part represents the length after the header containing the values for type and length. In this case, `tlv_len` should be: tlv_len == (sizeof(*tlv_rxba) - 1) - sizeof(tlv_rxba->header) + tlv_bitmap_len Notice that the `- 1` accounts for the one-element array `bitmap`, which 1-byte size is already included in `sizeof(*tlv_rxba)`. So, if the above is correct, there is a double-counting of some members in `struct mwifiex_ie_types_rxba_sync`, when `tlv_buf_left` and `tmp` are calculated: 968 tlv_buf_left -= (sizeof(*tlv_rxba) + tlv_len); 969 tmp = (u8 *)tlv_rxba + tlv_len + sizeof(*tlv_rxba); in specific, members: drivers/net/wireless/marvell/mwifiex/fw.h:777 777 u8 mac[ETH_ALEN]; 778 u8 tid; 779 u8 reserved; 780 __le16 seq_num; 781 __le16 bitmap_len; This is clearly wrong, and affects the subsequent decoding of data in `event_buf` through `tlv_rxba`: 970 tlv_rxba = (struct mwifiex_ie_types_rxba_sync *)tmp; Fix this by using `sizeof(tlv_rxba->header)` instead of `sizeof(*tlv_rxba)` in the calculation of `tlv_buf_left` and `tmp`.

2023-08-25wifi: rtw88: usb: kill and free rx urbs on probe failureSascha Hauer1-1/+4
After rtw_usb_alloc_rx_bufs() has been called rx urbs have been allocated and must be freed in the error path. After rtw_usb_init_rx() has been called they are submitted, so they also must be killed. Add these forgotten steps to the probe error path. Besides the lost memory this also fixes a problem when the driver fails to download the firmware in rtw_chip_info_setup(). In this case it can happen that the completion of the rx urbs handler runs at a time when we already freed our data structures resulting in a kernel crash.

Clang is a little more pedantic than GCC, which does not warn when falling through to a case that is just break or return. Clang's version is more in line with the kernel's own stance in deprecated.rst, which states that all switch/case blocks must end in either break, fallthrough, continue, goto, or return. Add the missing break to silence the warning.

The ENV_MNTR(environment monitor) is the dynamic mechanism which based on the HW of CCX(Cisco Compatible Extensions) which provide the channel loading and noisy level indicator to debug or support the 802.11k. The PHYSTS provide the detail PHY information per packet we received for debugging. The DIG(dynamic initial gain) is the dynamic mechanism to adjust the packet detect power level by received signal strength to avoid false detection of the WiFi packet. The address of registers used for ENV_MNTR, PHYSTS and DIG of WiFi 7 IC are different with WiFi 6 series, so we modify the method to access the register address in order to compatible with all WiFi 7 and 6 ICs.

cr_base is base address of PHY control register. The base of WiFi 6 and 7 chips are 0x1_0000 and 0x2_0000 respectively, so define them accordingly. For example, if PHY address is 0x1330, absolute address is 0x1_1330 for WiFi 6 chips, and 0x2_1330 for WiFi 7 chips. Meanwhile, there are two copies of PHY hardware named PHY0 and PHY1. The offset between them is 0x2_0000, so the base address of PHY0 and PHY1 are 0x2_0000 and 0x4_0000 respectively.

To diagnose abnormal behavior, we need to dump certain internal memory. For example, dump security CAM when debugging encryption/decryption problems, or dump BA CAM when debugging abnormal BlockAck. Since the indirect address and internal memory base address are different between WiFi 6 and 7 chips, add fields to reuse codes. Also, only WiFi 6 chips initialize DMAC and CMAC tables via this indirect interface, so no need to change the constant register address, and new firmware will help to initialize these tables.

However, the other detail coding of MCC start/stop will be implemented in the following. Besides, chanctx listener struct is pre-added in chip info. Each component can add callback type in chanctx listener and configure its callback function to react according to chanctx states.

A mouse that uses a USB connection is called a "USB mouse" device (or "USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi adapter that connects to the host computer via USB is a "USB wireless" device, not a "wireless USB" device. (The latter term more properly refers to a defunct Wireless USB specification, which described a technology for sending USB protocol messages over an ultra wideband radio link.) Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a "PCIe wireless" device, not a "wireless PCIe" device. Rephrase the text in the kernel source where the word ordering is wrong.

Currently when ath12k_dp_cc_desc_init() is called we allocate memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during descriptor cleanup rx_descs and tx_descs memory is not freed. This is cause of memory leak. These allocated memory should be freed in ath12k_dp_cc_cleanup. In ath12k_dp_cc_desc_init(), we can save base address of rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), we can free rx_descs and tx_descs memory using their base address.

2023-08-23wifi: ath5k: ath5k_hw_get_median_noise_floor(): use swap()Mahmoud Maatuq1-16/+13
coccinielle reported the following: ./drivers/net/wireless/ath/ath5k/phy.c:1573:25-26: WARNING opportunity for swap() while trying to fix the above warning, it reveals that ath5k_hw_get_median_noise_floor() had open-coded sort() functionality. Since ath5k_hw_get_median_noise_floor() only executes once every 10 seconds, any extra overhead due to sort() calling its "compare" and "swap" functions can be ignored, so replace the existing logic with a call to sort().
