hostapd:SAE: Confirm mismatch with H2E

[RAGHAVENDRA SADARAMACHANDRA (rsadaram)]

Hi,
 
Just searching for H2E is not enough. I don't have specific patch list I applied. However I followed below approach. 
 
git clone git://w1.fi/srv/git/hostap.git
cd hostap-master
git log --oneline de4d62dbc...d1fb06c94 > ~/git_log_de4d62dbc_d1fb06c94.txt
egrep -ri 'hash-to|H2E|PWE|SAE|rsn'  ~/git_log_de4d62dbc_d1fb06c94.txt > ~/filtered_de4d62dbc_d1fb06c94.txt
 
These gave me list of commits related to H2E for hostapd, wpa_supplicant and src folder in filtered_de4d62dbc_d1fb06c94.txt
Patched individual required diffs to our hostapd.

    Hi Raghu,

    I'd also be interested in using SAE H2E on OpenWrt 19.07, which is
    based on hostapd from 2019-08-08 (ca8c2bd28ad).

    Do you have a list of patches you ported to hostap 2.9? With
    "git log --oneline --all --grep='H2E'" I get a list of 65 patches
    (or 42 without the tests), but I'm not sure if they'd be
    sufficient.

    Regards, Linus
