A question Luis. Looking at the code (and not knowing _anything_ about
wireless internals):
- if (sc->sc_keytype == ATH9K_CIPHER_WEP)
+ if (tx_info->control.hw_key->alg == ALG_WEP)
txctl->keytype = ATH9K_KEY_TYPE_WEP;
- else if (sc->sc_keytype == ATH9K_CIPHER_TKIP)
+ else if (tx_info->control.hw_key->alg == ALG_TKIP)
txctl->keytype = ATH9K_KEY_TYPE_TKIP;
- else if (sc->sc_keytype == ATH9K_CIPHER_AES_CCM)
+ else if (tx_info->control.hw_key->alg == ALG_CCMP)
txctl->keytype = ATH9K_KEY_TYPE_AES;
I'm confused regarding the AES cypher. My AP is set through its
interface as:
Security Mode: WPA-Personal
WPA Mode: WPA2 Only
Cipher Type: AES
Group Key Update Interval: 2461 seconds (~41 minutes)
Pre-Shared Key: Loooong long key.
But the output from "iwlist scan" tells another story:
Encryption key:on
IE: IEEE 802.11i/WPA2 Version 1
Group Cipher : TKIP
Pairwise Ciphers (1) : TKIP
Authentication Suites (1) : PSK
So someones lying... Does this effect ath9k?
I'll compile another kernel and try to get rid of TKIP stuff completely
to test this out. At the moment the environment looks like this:
grep -i tkip my-.config
grep -i michael my-.config
# CONFIG_CRYPTO_MICHAEL_MIC is not set
grep -i ecb my-.config
CONFIG_CRYPTO_ECB=m
grep -i aes my-.config
CONFIG_CRYPTO_AES=m
CONFIG_CRYPTO_AES_X86_64=m
[EMAIL PROTECTED]:~$ lsmod|grep -i ecb
ecb 1344 2
crypto_blkcipher 8964 1 ecb
crypto_algapi 6336 6
aes_x86_64,aes_generic,arc4,ecb,crypto_blkcipher,cryptomgr
[EMAIL PROTECTED]:~$ lsmod|grep -i aes
aes_x86_64 6784 3
aes_generic 25576 1 aes_x86_64
crypto_algapi 6336 6
aes_x86_64,aes_generic,arc4,ecb,crypto_blkcipher,cryptomgr
Perhaps I'll break ath9k if the kernel lets me compile without an ecb
module...
