The channel configuration of 8852BT is very similar but a little different to 8852B, so use chip ID as condition to add extra handles including external loss compensation, ADC configurations, spur settings and so on. Don't affect existing 8852BE. Signed-off-by:

New upcoming chip is RTL8852BE-VT (or RTL8852BTE; 8852BT PCIE interface), which is a variant of 8852B, and many codes excepting to RF calibration can be shared, so move common code to an new kernel module named rtw89_8852b_common.ko. No logic change. Signed-off-by:

There is a confusing pattern in the kernel to use a variable named 'timeout' to store the result of wait_for_completion_timeout() causing patterns like: timeout = wait_for_completion_timeout(...) if (!timeout) return -ETIMEDOUT; with all kinds of permutations. Use 'time_left' as a variable to make the code self explaining. Signed-off-by:

This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "cmd_buf" variable is a pointer to "struct at76_command" and this structure ends in a flexible array: struct at76_command { [...] u8 data[]; } __packed; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the calculation "size + count" in the kmalloc() function. Also, declare a new variable (total_size) since the return value of the struct_size() helper is used several times. At the same time, prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). In this case, it is important to note that the attribute used is "__counted_by_le" since the counter type is "__le16". This way, the code is more readable and safer.

It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). This patch has no effect on runtime behavior. At the same time remove some redundant NULL initializations. Signed-off-by:

When EMLSR gets unblocked, the current code checks if the last exit was due to an EXIT reason (as opposed to a BLOCKING one), and if so, it does nothing, as in this case a MLO scan was scheduled to run in 30 seconds. But the code doesn't consider the time that passed from the last exit, so if immediately after the exit a blocker occurred (e.g. non-BSS interface), and lasts for more than 30 seconds, then the MLO scan and the following link selection will decide not to enter EMLSR, and when the unblocking event finally happens, the reason is still set to the EXIT one, so it will do nothing, and we will not have the chance to re-enable EMLSR. Fix this by checking also the time that has passed since the last exit, only if it is less than 30 seconds, we can count on the scheduled MLO scan. Note that clearing the reason itself can't be done since it is needed for the EMLSR prevention mechanism.

This was needed when we had multiple types of transports. Now we only have pcie, so there is no need for this ops. Cleanup the code such as the different trans APIs will call the pcie function directly, instead of calling the callback, and remove struct iwl_trans_ops. Signed-off-by:

The TX queue code was mostly moved out to support an internal transport that we were never going to publish, but we're no longer using that. Since we're also going to be dissolving the virtual transport layer entirely, integrate the TX queue code into the PCIe layer. This also has a small kernel of already removing the virtual transport function layer, since iwl_trans_send_cmd() calls iwl_trans_pcie_send_hcmd() directly now, even if that still calls the transport send_cmd method for now, we'll clean it up later. Also, not everything is renamed yet. Signed-off-by:

This really isn't correct to be in the opmode, do the clamping (and power-of-2 fixup that may be necessary due to this, or even otherwise) in the queue code. Also move down the retrying of the allocation, it should be after all the size fixups, but also it just makes sense, and avoids retrying same-size allocations in the case of the BZ-family A-step workaround.

If a user uses iw to connect to a network and we don't have any information about the existing networks, cfg80211 will trigger a scan internally even if the user didn't ask for a scan. This scan is implemented by cfg80211_conn_scan(). This function called rdev_scan() directly without honoring the WIPHY_FLAG_SPLIT_SCAN_6GHZ flag. Use cfg80211_scan instead, this will split the scan if the low level driver asked to. Signed-off-by:

When e.g. wpa_supplicant sets only the MLD "sta" authorized state, the code actually applies that change, but then returns an error to userspace anyway because there were no changes to the link station, and no link ID was given. However, it's not incorrect to not have a link ID when wanting to change only the MLD peer ("sta") state, so the code shouldn't require it. To fix this, separate the "new_link" argument out into a new three-state enum, because if modify is called on a link STA only, it should return an error if no link is given or if it doesn't exist. For modify on the MLD "sta", not having a link ID is OK, but if there is one it should be validated. This seems to not have mattered much as wpa_supplicant just prints a message and continues, and the authorized state was already set before this error return. However, in the later code powersave recalculation etc. will be skipped, so that it may result in never allowing powersave on MLO connections. Signed-off-by: -

To later introduce an override for VLP APs being allowed despite NO-IR flags, which is somewhat similar in construction to being allowed to monitor on disabled channels, refactor the code that checks channel flags to have not a 'monitor' argument but a set of 'permitting' flags that permit the operation without checking for 'prohibited' flags.

Commit 3e2f544d ("net: get stats64 if device if driver is configured") moved the callback to dev_get_tstats64() to net core, so, unless the driver is doing some custom stats collection, it does not need to set .ndo_get_stats64. Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64 function pointer. In this driver specifically, .ndo_get_stats64 basically points to dev_fetch_sw_netstats(). Now it will point to dev_get_tstats64(), which calls netdev_stats_to_stats64() and dev_fetch_sw_netstats(). netdev_stats_to_stats64() seems irrelevant for this driver. Signed-off-by:

Jiazi Li reported that they occasionally see hash table duplicates as evidenced by the WARN_ON() in rb_insert_bss() in this code. It isn't clear how that happens, nor have I been able to reproduce it, but if it does happen, the kernel crashes later, when it tries to unhash the entry that's now not hashed. Try to make this situation more survivable by removing the BSS from the list(s) as well, that way it's fully leaked here (as had been the intent in the hash insert error path), and no longer reachable through the list(s) so it shouldn't be unhashed again later.
