Adding this supports beacon filter and connection quality monitor. To make host CPU wake up less, let firmware perform signal monitoring and beacon processing, then notify driver upon signal changes or beacon loss. This feature needs firmware 0.27.56 or newer to support it. Signed-off-by:

The if statement here is misleading, we return zero anyway since we just checked the 'ret' variable, simplify the code to remove the condition entirely. 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:

Implement the full STA mask and selecting the correct link for key installation. While at it, catch errors if this function returns a bad zero station mask, rather than waiting for the firmware to crash on it. Signed-off-by:

If adding a key to firmware fails we leak the allocated ptk_pn. This shouldn't happen in practice, but we should still fix it. Signed-off-by:

We never needed this to be non-static, that was just an artifact of the development process. Make it static. 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:

On 22000 and AX210 devices, there's a ROM bug that causes it to set invalid LTR settings. On 22000 and AX210 non-integrated we can fix up these settings from the driver (as done in the code here), but on AX210 integrated these registers are not available to the driver. Attempt to work around the issue by spinning while the IML is being loaded, the IML will then reprogram the LTR values itself after it's loaded, so only the brief IML load (which the ROM is doing) is affected.

beacon_inject_active turns true and false via debugfs when we inject a beacon. During the time of the beacon injection we can't configure the FW with a beacon cmd. If we have a hw restart during the beacon injection then in the recovery flow we will not be able to configure the beacon cmd to the FW. Fix this by cleaning up this variable after an hw restart.

Some drivers like iwlwifi might have per-STA queues, so we may want to flush/drop just those queues rather than all when removing a station. Add a separate method for that. Signed-off-by: -
Johannes Berg authored
When we remove a station, we first make it unreachable, then we (must) remove its keys, and then remove the station itself. Depending on the hardware design, if we have hardware crypto at all, frames still sitting on hardware queues may then be transmitted without a valid key, possibly unencrypted or with a fixed key. Fix this by flushing the queues when removing stations so this cannot happen. Signed-off-by: -

The checks of whether or not a frame is bufferable were not taking into account that some action frames aren't, such as FTM. Check this, which requires some changes to the function ieee80211_is_bufferable_mmpdu() since we need the whole skb for the checks now. Reviewed-by:
