Hi Johannes, Thanks for your time on reviewing this. I will make changes following your review. See details below. By the way, I'm still struggling on how to run unit tests. It might take time for me to make it run on my machine. 2017-10-02 8:04 GMT-04:00 Johannes Berg <johannes@xxxxxxxxxxxxxxxx>: > Please use "v2" tag or so in the subject line, having the same patch > again is really not helpful. > > The next should be v3, obviously.

Hmm... good question. The reason is, aes_ccm.c and aes_gcm.c was almost exact copy of each other. But they have different copyright information. The copyright of aes_ccm.c was: Copyright 2006, Devicescape Software, Inc. Copyright 2003-2004, Instant802 Networks, Inc. and the copyright of aes_gcm.c was: Copyright 2014-2015, Qualcomm Atheros, Inc. I just don't know how to write the copyright for the new aead_api.c, so I does not put anything there. These copyright information are still at aes_ccm.h and aes_gcm.h What's your opinion on writing these copyright information? Do I write all of them? like: Copyright 2014-2015, Qualcomm Atheros, Inc.

This was because I was planning to put it to crypto directory, then I changed it to the same name as in other crypto api. Now that it will goes to the mac80211, I think it is time to revert this change. > >> @@ -540,10 +541,11 @@ ieee80211_crypto_ccmp_decrypt(struct >> ieee80211_rx_data *rx, >> ccmp_special_blocks(skb, pn, b_0, aad); >> >> if (ieee80211_aes_ccm_decrypt( >> - key->u.ccmp.tfm, b_0, aad, >> - skb->data + hdrlen + IEEE80211_CCMP_HDR_LEN, >> - data_len, >> - skb->data + skb->len - mic_len, mic_len)) >> + key->u.ccmp.tfm, b_0, aad, >> + skb->data + hdrlen + IEEE80211_CCMP_HDR_LEN, >> + data_len, >> + skb->data + skb->len - key->u.ccmp.tfm->authsize >> + )) >> return RX_DROP_UNUSABLE; > > That's a really really strange way of writing this ... > > Please reformat.
