It's been observed that in a corner case mwifiex_usb_tx_complete() gets called before we exit from mwifiex_usb_host_to_card() after submitting the urb. 'data_sent' flag remains set in this case. It blocks further Tx packets and triggers watchdog timeout. The problem is fixed by setting data_sent and port_block flag at correct place. Signed-off-by:

We may end up attaching new skb to URB in a corner case and same will be freed. This results in the kernel crash. The problem is solved by changing the sequence. Signed-off-by:

The 802.11 standard only has four valid auth type configurations of which our firmware only supports two, ie. Open System and Shared Key. Simplify the mapping falling back to automatic for other types specified by user-space. Reviewed-by:

Clearing the wowl wakeindicator happens with a rather odd construction where the string "clear" is used to set the iovar wowl_wakeind. This was implemented incorrectly as it caused an out of bound access. Use an intermediate variable of correct length and copy string in that. Problem was found using coverity. Reviewed-by:

When IPv6 address is to be cleared there is a possible out of bound access. But also the clearing of the last entry and the adjustment of total number of stored IPv6 addresses is not updated. This patch fixes that bug. Bug was found using coverity. Reviewed-by:

The variable info is assigned to point to bcdc->msg[1], which is the same as pointing to bcdc->buf. As that is what we want to access make it clear by fixing the assignment. This also avoid out-of-bounds errors from static analyzers are bcdc->msg[1] is not in the structure definition. Reviewed-by:

802.11d is not always supported by firmware anymore. Currently the AP configuration of 11d will cause an abort if the ioctl set is failing. This behavior is not correct and the error should be ignored. Reviewed-by:

Booting multiple wl12xx and wl18xx devices using the same rootfs is a pain. You currently have to symlink the right nvs file depending on the wl12xx type. For example, with wl1271-nvs.bin being a symlink to wl127x-nvs.bin by default and trying to bring up a wl128x based device: wlcore: ERROR nvs size is not as expected: 1113 != 912 wlcore: ERROR NVS file is needed during boot wlcore: ERROR NVS file is needed during boot wlcore: ERROR firmware boot failed despite 3 retries Note that wl18xx uses a separate config firmware wl18xx-conf.bin that can be generated with tools using the following two git repos: git.ti.com/wilink8-wlan/18xx-ti-utils git.ti.com/wilink8-wlan/wl18xx_fw So let's not configure the nvs file for wl18xx as it's not needed AFAIK. If it turns out that we also need the nvs file for wl18xx, we can just add it to the config firmware data for wl18xx. Let's fix the issue by using the chip specific config firmware data, and make sure we produce understandable warnings if something is missing. Signed-off-by:

Move struct wilink_family_data to be available for all TI WLAN variants. And fix familiy typo, it should be just family. Looks like wl12xx use two different nvs.bin files and wl18xx uses a different conf.bin file. Signed-off-by:

In order to access cached/paged memory, there are a couple of firmware commands (one for UMAC and one for LMAC) that let the host access memory and registers indirectly. Since this is done by the firmware on behalf of the host, even if memory is paged out or cached, the host will retrieve the memory as the firmware sees it (paged out memory will get paged in). Export this mechanism via a debugfs entry for both read and write access. WARNING: This mechanism has no protections at all. Invalid addresses may crash or hang the firmware. Writing to arbitrary memory also comes with no guarantees. Signed-off-by:

There's no need for the common MAC context function to have an if on AP mode, the values can be overridden in the AP-specific function later. Clean that up by adding the full command as a new parameter to the AP-specific function, and doing it there. Signed-off-by:

There was recently a Full AP mode feature added where hostap adds the station at auth stage, and not assoc. However, when running with legacy hostapd, we get the auth response before station was added, and tx_skb_non_sta fails to allocate a queue, resulting in a complete failure of association. Take care of this situation as well. Add a warning when no valid queue is returned at all and make mvm drop the packet instead of passing it on. Refactor the function a bit while at it.
