Use the in-kernel structure and flags instead of defining a separate one. The rtw_ieee80211_channel structure and flags can be replaced by the ieee80211_channel defined in include/net/cfg80211.h since the flags serve the same purpose and the ieee80211_channel struct includes the elements used in the rtw_ieee80211_channel struct.

Unlike mlme_sta_tbl, OnAction_tbl is an array of structs. OnAction iterates over the array to find the entry for a specific action category. No action is performed if a category has no entry. We can remove the entries that point to the dummy function DoReserved. These were the last users of DoReserved, the function itself can be removed as well. Signed-off-by:

Remove the empty OnAtim function. We can set the function pointer in mlme_sta_tbl to NULL if no action is required for this management frame subtype. Signed-off-by:

The rtllib_rx_assoc_resp() function has a signedness bug because it's a declared as a u16 but it return -ENOMEM. When you look at it more closely it returns a mix of error codes including 0xcafe, -ENOMEM, and a->status which is WLAN_STATUS_NOT_SUPPORTED_AUTH_ALG. This is a mess. Clean it up to just return standard kernel error codes. We can print out the a->status before returning a regular error code. The printks in the caller need to be adjusted as well. Reviewed-by:

Currently, these three get_key functions return -1 when the provided len value is less a specific key length value, which can result in buffer overflow depending on how the returned value is used. These functions are used in three places in ieee80211/ieee80211_wx.c: ieee80211_wx_get_encode() : The behavior of this function will be unchanged. ieee80211_wx_get_encode_ext() : The result of the get_key function is written to ext->key_len, resulting in a buffer overflow if the result is negative. ieee80211_wx_set_encode() : The behavior of this function will change. When len is less than the key length value, it will set a default key of all 0.

There is a deadlock in rtllib_beacons_stop(), which is shown below: (Thread 1) | (Thread 2) | rtllib_send_beacon() rtllib_beacons_stop() | mod_timer() spin_lock_irqsave() //(1) | (wait a time) ... | rtllib_send_beacon_cb() del_timer_sync() | spin_lock_irqsave() //(2) (wait timer to stop) | ... We hold ieee->beacon_lock in position (1) of thread 1 and use del_timer_sync() to wait timer to stop, but timer handler also need ieee->beacon_lock in position (2) of thread 2. As a result, rtllib_beacons_stop() will block forever. This patch extracts del_timer_sync() from the protection of spin_lock_irqsave(), which could let timer handler to obtain the needed lock.

Add " == 0" to the condition in both else if branches to address a possible bug. strcmp returns 0 when its arguments are equal, which evaluates to false, often leading to errors when used in if statements. Currently, the statement in the first else if branch does not execute when its arguments are equal, but it does execute when crypt->ops->name equals any string other than "WEP" or "TKIP". Similarly, the second else if branch does not execute when its arguments are equal, and it only executes when crypt->ops->name equals "TKIP". The else branch never executes. It is unlikely that this is working as intended. Reviewed-by:

The Unisys sub-tree of drivers/staging contains three drivers for the "Unisys Secure Partition" (s-Par(R)): visorhba, visorinput, visornic. They have no maintainers, in fact the only one that is listed in MAINTAINERS has an unreacheable email address. During 2021 and 2022 several patches have been submitted to these drivers but nobody at Unisys cared of reviewing the changes. Probably, also the "sparmaintainer" internal list of unisys.com is not anymore read by interested Unisys' engineers. Therefore, remove the drivers/staging/unisys directory and delete the relevant entries in the MAINTAINERS, Kconfig, Makefile files, then remove also the drivers/visorbus directory which is not anymore needed (it contained the driver for the virtualized bus for the Unisys s-Par firmware).
