The usage of the 'dtim_period' value was wrong, as it is only a multiplier of the beacon interval, and thus, beacon interval should also be considered. Fix it. Signed-off-by:

In iwl_mvm_mac_ctxt_get_lowest_rate() we were still accessing vif->bss_conf without any multi-link provisions, and also the info->band, both of which isn't valid in MLO. Fix the code to look at the correct link. In case of EAPOL transmissions for the initial 4-way-HS, look up the correct link here as well, and warn if multiple are active. Signed-off-by:

Add SDIO ids for use with the muRata 1YN (Cypress CYW43439). The odd thing about this is that the previous 1YN populated on M.2 card for evaluation purposes had BRCM SDIO vendor ID, while the chip populated on real hardware has a Cypress one. The device ID also differs between the two devices. But they are both 43439 otherwise, so add the IDs for both. On-device 1YN (43439), the new one, chip label reads "1YN": ``` /sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device 0x04b4 0xbd3d ``` EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4": ``` /sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device 0x02d0 0xa9a6 ``` Reviewed-by:

These tables contain BB and RF parameters that driver will load them into registers. It also contains TX power according to country, band, rate and so on. Increasing thermal can cause TX power degraded, so power tracking tables are defined to compensate TX power.

One chip can have different RFE (RF front end) types which we will judge at runtime. And, different RFE types may use different RF parameter tables. Though we didn't really meet this case previously, we are going to meet it on upcoming chip RTL8851B. So, this commit handles parameter tables for runtime RFE type. We now encapsulate rtw89_txpwr_rule_<2/5/6>ghz tables into rtw89_rfe_parms. Then, each chip defines its default parameter tables, and if needed, it can configure extra parameter tables by RFE type. Finally we determine runtime parameter tables by RFE type if one is configured. Otherwise, we use the default parameter tables. For now, we just move all settings under default parameter tables. We will configure parameter tables by RFE types in separate commits afterwards. Signed-off-by:

In the discuss threads [1] [2], new firmware format break user space because older drivers can't recognize new firmware format. To avoid this, the new format will be named rtw89/rtw8852b_fw-1.bin and only new driver try to load it. Old drivers only load original and understandable firmware rtw89/rtw8852b_fw.bin. More, new driver will be still backward compatible with old firmware, so original firmware can be used by new driver. If there is newer firmware format is introduced, rtw89/rtw8852b_fw-2.bin will be given. The same rules will be applied like above. So, we will have firmware like below in linux-firmware in the future. rtw89/rtw8852b_fw-2.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852b_fw.bin After this patch, MODULE_FIRMWARE() of 8852A/B/C become rtw89/rtw8852a_fw.bin rtw89/rtw8852b_fw-1.bin rtw89/rtw8852c_fw.bin [1] https://lore.kernel.org/linux-wireless/df1ce994-3368-a57e-7078-8bdcccf4a1fd@gmail.com/T/#m24cb43be31a762d0ea70bf07f27ae96c59f6931b [2] https://bugzilla.kernel.org/show_bug.cgi?id=217207Signed-off-by:

Since we are going to load more than one firmware and some are not presented or optional, using asynchronous API request_firmware_nowait() will become complicated. Also, we want to use firmware_request_nowarn() to avoid warning messages when loading optional files. So, use schedule_work to be simpler. To abstract loading a firmware or file, define a struct rtw89_fw_req_info containing a struct firmware and a completion to ensure this firmware is loaded completely. Signed-off-by:

In early feature bitmap obtained from rtw89_early_fw_feature_recognize(), the bits needed to check get increased. It's more friendly to work with RTW89_CHK_FW_FEATURE(). So, we concentrate the flow of iterating FW feature configures and calling RTW89_SET_FW_FEATURE() for various uses. And then, we adjust rtw89_early_fw_feature_recognize() for RTW89_CHK_FW_FEATURE().

We used to store operating channel info after associated. However, scan might happen before that. Without switching back to operating channel, authentication or association might fail. Therefore, we switch back to operating channel when the scanning vif's BSSID is non-zero, which implies connected or during attempt to connect. Signed-off-by:

Use POWER_ON flag to make sure power on/off is symmetric. Since both remain_on_channel and hw_scan both alter the power state, this makes sure that we don't enter/leave IPS mode twice. Also, replace IPS related functions with inline function that does similar logic so we can track it more easily. Signed-off-by:

Add support of remain on channel ops. Since channel context is required to enable multi-channel concurrent(MCC) and the current ROC in mac80211 don't support more than 1 channel context, add this to let P2P and other protocols relying on this work as expected. The off-channel duration and cancel timing is purely controlled by upper layers. Signed-off-by:

The setting of the rate used for non station cases did not take into consideration the interface type etc., thus when probe responses are transmitted on P2P Device interface etc. CCK rates were used which is not allowed. Modify the code so the non station case would consider the interface type etc. For HWs/FWs that do not support rate control, preserve the previous behavior, i.e., take the rate from the skb metadata and adjust as needed.

If we have MLO, then the deflink.ap_sta_id cannot be used. However, we can use the new mvmvif->ap_sta pointer for the validation instead. Also don't do it multiple times for different FW instances of the same AP STA (TDLS STAs are only on a single link). Note that this isn't really working right yet since the underlying flush code hasn't been updated yet to know of multiple link STAs. Signed-off-by:

Instead of relying on the AP STA ID and dereferencing our firmware -> mac80211 STA array when we really only need the STA, not the per-link information (and might not have it, e.g. for a pairwise key installation where this is relevant), keep track of the AP STA as a pointer to the mac80211 STA, protected by the mutex. Then use it here in the key code instead. Signed-off-by:

An integer overflow occurs in the iwl_write_to_user_buf() function, which is called by the iwl_dbgfs_monitor_data_read() function. static bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count, void *buf, ssize_t *size, ssize_t *bytes_copied) { int buf_size_left = count - *bytes_copied; buf_size_left = buf_size_left - (buf_size_left % sizeof(u32)); if (*size > buf_size_left) *size = buf_size_left; If the user passes a SIZE_MAX value to the "ssize_t count" parameter, the ssize_t count parameter is assigned to "int buf_size_left". Then compare "*size" with "buf_size_left" . Here, "buf_size_left" is a negative number, so "*size" is assigned "buf_size_left" and goes into the third argument of the copy_to_user function, causing a heap overflow. This is not a security vulnerability because iwl_dbgfs_monitor_data_read() is a debugfs operation with 0400 privileges. Signed-off-by:Hyunwoo Kim <imv4bel@gmail.com> Signed-off-by:
