There are sleep in atomic context bugs when dm_fsync_timer_callback is
executing. The root cause is that the memory allocation functions with
GFP_KERNEL or GFP_NOIO parameters are called in dm_fsync_timer_callback
which is a timer handler. The call paths that could trigger bugs are
shown below:
(interrupt context)
dm_fsync_timer_callback
write_nic_byte
kzalloc(sizeof(data), GFP_KERNEL); //may sleep
usb_control_msg
kmalloc(.., GFP_NOIO); //may sleep
write_nic_dword
kzalloc(sizeof(data), GFP_KERNEL); //may sleep
usb_control_msg
kmalloc(.., GFP_NOIO); //may sleep
This patch uses delayed work to replace timer and moves the operations
that may sleep into the delayed work in order to mitigate bugs.

The ieee80211_check_auth_response() 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.

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 ieee80211_beacons_stop(), which is shown below:
(Thread 1) | (Thread 2)
| ieee80211_send_beacon()
ieee80211_beacons_stop() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | ieee80211_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, ieee80211_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.

Tasklets have long been deprecated as being too heavy on the system
by running in irq context - and this is not a performance critical
path. If a higher priority process wants to run, it must wait for
the tasklet to finish before doing so.
rtllib_sta_ps() and ieee80211_sta_ps() will now run in process context
and have further concurrency (tasklets being serialized among themselves),
but this is done holding the ieee->lock, so it should be fine.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
In this case these aren't actually dynamic sizes: both sides of the
multiplication are constant values. However it is best to refactor these
anyway, just to keep the open-coded math idiom out of code.
So, use the purpose specific kcalloc() function instead of the argument
size * count in the kzalloc() function.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
Split the 3 addr memcpy() into 3 memcpy() calls so the compiler doesn't
think an overflowing memcpy() happens against the addr1 field (the
neighbors are intended to be copied as well).
ieee80211_read_qos_param_element() copies a struct ieee80211_info_element
into a struct ieee80211_qos_information_element, but is actually wanting to
copy into the larger struct ieee80211_qos_parameter_info (the contents of
ac_params_record[] is later examined). Refactor the routine to perform
centralized checks, and copy the entire contents directly (since the id
and len members match the elementID and length members):
struct ieee80211_info_element {
u8 id;
u8 len;
u8 data[];
} __packed;
struct ieee80211_qos_information_element {
u8 elementID;
u8 length;
u8 qui[QOS_OUI_LEN];
u8 qui_type;
u8 qui_subtype;
u8 version;

struct ieee80211_qos_information_element info_element;
u8 reserved;
struct ieee80211_qos_ac_parameter ac_params_record[QOS_QUEUE_NUM];
} __packed;
Additionally replace old-style zero-element arrays with flexible arrays.

The for-loop iterates with a u8 loop counter i and compares this
with the loop upper limit of riv->ieee80211->LinkDetectInfo.SlotNum
that is a u16 type. There is a potential infinite loop if SlotNum
is larger than the u8 loop counter. Fix this by making the loop
counter the same type as SlotNum.
