The problem is that we always copy a minimum of ETH_ZLEN (60) bytes from
skb->data even when skb->len is less than ETH_ZLEN so it leads to a read
overflow.
The fix is to pad skb->data to at least ETH_ZLEN bytes.

The CCK TX setting when switch channel will fix the CCK to
path A only, so if the antenna is configured to path B
(e.g. iw phy set antenna 0x2 0x3 "TX B/RX AB"), then the CCK
packets can never be delivered to the air if only path B is
connected with an antenna (it can possibly be transmitted
through path A, but as path B is configured, the expected
behavior is incorrect).
This can also solve the racing issue of CCK TX setting between
driver and firmware. The CCK TX setting in driver should be
removed. Otherwise, the CCK TX setting would be wrong when the
racing occurs.

Connecting to an AP with WPA2 security may fail. The IQK
and the EAPOL 4-way handshake may overlap because the
driver does IQK right after assoc success.
For 802.11n devices, the IQK is done in the driver and it
could require more than 100ms to complete. During IQK, any
TX/RX events are paused. So if the EAPOL 4-way handshake
started before IQK finished, then the 1/4 and 2/4 part of
the handshake could be dropped. The AP will then issue
deauth with reason IEEE8021X_FAILED (23).
To resolve this, move IQK routine into managed TX prepare
(ieee80211_ops::mgd_prepare_tx()). The callback is called
before the managed frames (auth/assoc) are sent. This will
make sure that the IQK is completed before the handshake
starts. But don't do IQK during scanning because doing it
on each channel will take too long.
For 802.11ac devices, the IQK is done in firmware and it
takes less time to complete. Therefore we don't see a
failure during the EAPOL 4-way handshake. But it is still
worth moving the IQK into ieee80211_ops::mgd_prepare_tx().

Since the driver was first introduced into the kernel, it has only
handled the ciphers associated with WEP, WPA, and WPA2. It fails with
WPA3 even though mac80211 can handle those additional ciphers in software,
b43legacy did not report that it could handle them. By setting MFP_CAPABLE using
ieee80211_set_hw(), the problem is fixed.
With this change, b43legacy will handle the ciphers it knows in hardware,
and let mac80211 handle the others in software. It is not necessary to
use the module parameter NOHWCRYPT to turn hardware encryption off.
Although this change essentially eliminates that module parameter,
I am choosing to keep it for cases where the hardware is broken,
and software encryption is required for all ciphers.

This reverts commit 07d0f5534935e2daf63a4e1012af13d68e089fed.
For rtw88 driver, the SDIO is going to be supported, so there is
no need to remove the SDIO related power sequence settings. And
while the power sequence parser will pass in the mask of the HCI,
the SDIO part will not be used to set registers accordingly.
Moreover, the power sequence table is released as a whole package,
so the next time if we are going to update, the SDIO settings will
be overwritten. So, revert this now.

This patch drops the use of the static iterator, and instead every time
the function is called iterates to the idx-th position of the
linked-list.
It would be better to convert the code not to use linked list for
associated stations storage (since the chip has a limited number of
associated stations anyway - it could just be an array). Such a change
may be proposed in the future. In the meantime this patch can backported
into stable kernels in this simple form.

Rename the name of the kernel module for rtw88's core and pci.
Add proper prefix 'rtw88_' to easily recognize them, also can
avoid confusion with other drivers. (ex. r8822be in staging)

In the current design, chip entry points are built into
the pci module. That makes the pci module depend on chips.
According to dependence, once the pci module is loaded,
kernel will load chip functionalities, including those that
may not be currently used.
We plan to split chip entry points from the pci module.
Thence we export pci symbols that will be used in chip
entry point modules.

In the current design, various chip functions and tables
are built into rtw88 core. That causes kernel to load its
functionalities even if a chip isn't currently used. We
plan to make each chip's functionalities a separate
kernel module to reduce rtw88 core. And kernel will be
able to load the necessary.
Before extracting chip functionalities, we export symbols
inside rtw88 core which will be used in chip modules.

Seven years ago we tried to fix a leak but actually introduced a double
free instead. It was an understandable mistake because the code was a
bit confusing and the free was done in the wrong place. The "skb"
pointer is freed in both _rtl_usb_tx_urb_setup() and _rtl_usb_transmit().
The free belongs _rtl_usb_transmit() instead of _rtl_usb_tx_urb_setup()
and I've cleaned the code up a bit to hopefully make it more clear.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.
