Bug description:
  == Impact ==
  Marvell WiFi cards supported by the mwifiex driver may fail to connect to some access points after kernel upgrade.
  This is caused by the commit

  commit e18696786548244914f36ec3c46ac99c53df99c3
  Author: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
  Date:   Wed Jul 8 14:58:57 2020 +0300

      mwifiex: Prevent memory corruption handling keys
      
      The length of the key comes from the network and it's a 16 bit number.  It
      needs to be capped to prevent a buffer overflow.

  The commit added a check to mwifiex_ret_802_11_key_material_v2() to
  make sure the key length doesn't larger than the key buffer size
  before copying it. The allocated key buffer is 16-byte long. In some
  cases the key would be 32-byte long and hence the check fails. One
  thing to note is that this commit is not the cause of the problem,
  instead it just makes the issue visible.

  The commit is included in Ubuntu-4.4.0-190.220, Ubuntu-4.15.0-119.120,
  Ubuntu-5.4.0-48.52, and Ubuntu-5.8.0-18.19.

  == Fix ==
  There's already a fix in the mainline which increase the key buffer size to 32 bytes:

      mwifiex: Increase AES key storage size to 256 bits
      
      Following commit e18696786548 ("mwifiex: Prevent memory corruption
      handling keys") the mwifiex driver fails to authenticate with certain
      networks, specifically networks with 256 bit keys, and repeatedly asks
      for the password. The kernel log repeats the following lines (id and
      bssid redacted):
      
          mwifiex_pcie 0000:01:00.0: info: trying to associate to '<id>' bssid <bssid>
          mwifiex_pcie 0000:01:00.0: info: associated to bssid <bssid> successfully
          mwifiex_pcie 0000:01:00.0: crypto keys added
          mwifiex_pcie 0000:01:00.0: info: successfully disconnected from <bssid>: reason code 3
      
      Tracking down this problem lead to the overflow check introduced by the
      aforementioned commit into mwifiex_ret_802_11_key_material_v2(). This
      check fails on networks with 256 bit keys due to the current storage
      size for AES keys in struct mwifiex_aes_param being only 128 bit.
      
      To fix this issue, increase the storage size for AES keys to 256 bit.

  == Regression Potential ==
  Low. While the fix increases the buffer size, it still checks and make sure data to be copy can fit into the buffer. Also the commit does fix the issue we saw in the Cert lab.
