2023-10-23idpf: set scheduling mode for completion queueMichal Kubiak
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.

It has four programmable Network-on-Chip (NoC) interface ports and is designed to handle multiple streams of traffic. The driver reports correctable and uncorrectable errors, and also creates debugfs entries for testing through error injection.

strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. wl->chip.phy_fw_ver_str is obviously intended to be NUL-terminated by the deliberate comment telling us as much. Furthermore, its only use is drivers/net/wireless/ti/wlcore/debugfs.c shows us it should be NUL-terminated since its used in scnprintf: 492 | DRIVER_STATE_PRINT_STR(chip.phy_fw_ver_str); which is defined as: | #define DRIVER_STATE_PRINT_STR(x) DRIVER_STATE_PRINT(x, "%s") ... | #define DRIVER_STATE_PRINT(x, fmt) \ | (res += scnprintf(buf + res, DRIVER_STATE_BUF_LEN - res,\ | #x " = " fmt "\n", wl->x)) We can also see that NUL-padding is not required. Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. The very fact that a plain-english comment had to be made alongside a manual NUL-byte assignment for such a simple purpose shows why strncpy is faulty. It has non-obvious behavior that has to be clarified every time it is used (and if it isn't then the reader suffers).

2023-10-23wifi: ipw2x00: replace deprecated strncpy with strscpy_padJustin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. `extra` is intended to be NUL-terminated which is evident by the manual assignment of a NUL-byte as well as its immediate usage with strlen(). Moreover, many of these getters and setters are NUL-padding buffers with memset(): 2439 | memset(&tx_power, 0, sizeof(tx_power)); 9998 | memset(sys_config, 0, sizeof(struct ipw_sys_config)); 10084 | memset(tfd, 0, sizeof(*tfd)); 10261 | memset(&dummystats, 0, sizeof(dummystats)); ... let's maintain this behavior and NUL-pad our destination buffer. Considering the above, a suitable replacement is `strscpy_pad` due to the fact that it guarantees both NUL-termination and NUL-padding on the destination buffer. To be clear, there is no bug in the current implementation as MAX_WX_STRING is much larger than the size of the string literals being copied from. Also, strncpy() does NUL-pad the destination buffer and using strscpy_pad() simply matches that behavior. All in all, there should be no functional change but we are one step closer to eliminating usage of strncpy(). Do note that we cannot use the more idiomatic strscpy invocation of (dest, src, sizeof(dest)) as the destination buffer cannot have its size determined at compile time. So, let's stick with (dest, src, LEN).

2023-10-23wifi: rt2x00: fix rt2800 watchdog functionShiji Yang
The watchdog function is broken on rt2800 series SoCs. This patch fixes the incorrect watchdog logic to make it work again. 1. Update current wdt queue index if it's not equal to the previous index. Watchdog compares the current and previous queue index to judge if the queue hung. 2. Make sure hung_{rx,tx} 'true' status won't be override by the normal queue. Any queue hangs should trigger a reset action. 3. Clear the watchdog counter of all queues before resetting the hardware. This change may help to avoid the reset loop. 4. Change hang check function return type to bool as we only need to return two status, yes or no.

`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces.

However, now a length-bounded strncmp is used: | if (strncmp(cmd->policy_name, policy_name, sizeof(cmd->policy_name))) ... which means NUL-terminated may not strictly be required. However, I believe the intent of the code is clear and we should maintain NUL-termination of policy_names. Moreover, __begin_transaction_flags() zero-allocates `cmd` before calling read_superblock_fields(): | cmd = kzalloc(sizeof(*cmd), GFP_KERNEL); Also, `disk_super->policy_name` is zero-initialized | memset(disk_super->policy_name, 0, sizeof(disk_super->policy_name)); ... therefore any NUL-padding is redundant. Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

Let's instead use memcpy() as this more properly relays the intended behavior. Do note that ec_fw_string will still end up being NUL-terminated since we are memcpy'ing only 8 bytes into a buffer full of 18 zeroes. There's still some trailing NUL-bytes there. To ensure this behavior, let's add a BUILD_BUG_ON checking the length leaves space for at least one trailing NUL-byte.

Revert the remains of it back to almost the original scheme, but now expanded to track per-DTC indices, in preparation for making use of them in anger.

2023-10-23spi: omap2-mcspi: Add FIFO support without DMAVaishnav Achath
Currently, the built-in 64-byte FIFO on the MCSPI controller is not enabled in PIO mode and is used only when DMA is enabled. Enable the FIFO in PIO mode by default for transactions larger than the FIFO depth and fallback only if FIFO is not available. When DMA is not enabled, it is efficient to enable the RX FIFO almost full and TX FIFO almost empty events after each FIFO fill instead of each word. Update omap2_mcspi_set_fifo() to enable the events accordingly and also rely on OMAP2_MCSPI_CHSTAT_RXS for the last transfer instead of the FIFO events to handle the case when the transfer size is not a multiple of FIFO depth.

2023-10-23wifi: iwlwifi: mvm: cycle FW link on chanctx removalJohannes Berg
When the vif is in MLD mode, we'll get a vif links change from non-zero to zero on disassociation, which removes all links in the firmware and adds the 'deflink' the driver/mac80211 has. This causes the firmware to clear some internal state. However, in non-MLD mode, this doesn't happen, and causes some state to be left around in firmware, which can particularly cause trouble with the ref-BSSID in multi-BSSID, leading to an assert later if immediately making a new multi-BSSID connection with a different ref-BSSID. Fix this by removing/re-adding the link in the non-MLD case when the channel is removed from the vif. This way, all of the state will get cleared out, even if we need the deflink, which is more for software architecture purposes than otherwise.
