Re: [Madwifi-devel] TKIP crashes kernel, AES works...

[Alfred A. <al...@cc...>]

Hi,

just a thought: TKIP-encrypting a frame makes it altogether 20 bytes
longer (8 bytes EIV, 8 bytes Michael hash, 4 bytes ICV).  Maybe the
software-based TKIP doesn't properly extend the tx buffer.  AES makes a
frame only 16 bytes longer (8 bytes EIV, 8 bytes hash), and if either is
computed by hardware, the hash/ICV portions are appended automatically by
hardware, so they aren't present in the tx buffer at all.  Just an idea
where to search...

Best regards

Alfred Arnold
