[PATCH v3] ath10k: add 'cryptmode' param to support raw tx injection and software crypto
Liu CF/TW
cfliu.tw at gmail.com
Mon Jun 8 18:13:02 PDT 2015
This change supports hardware crypto engine bypass by enabling raw
Rx/Tx encap mode. This enables use cases such as software crypto and raw
tx injection. This change introduces a new module param 'cryptmode'.
cryptmode:
0: Use hardware crypto engine globally with native Wi-Fi mode TX/RX
encapsulation to the firmware. This is the default mode.
1: Use sofware crypto engine globally with raw mode TX/RX encapsulation
to the firmware.
2: Supports both hardware and software crypto with raw mode TX/RX
encapsulation to the firmware. By default hardware crypto engine is
used. To use software crypto in this mode, set the per ath10k_vif
'nohwcrypt' flag value to True.*
*) The patch for setting vif specific 'nohwcrypt' flag when
cryptmode=2 would be a separate patch to mac80211.
Possible use case examples:
- Use software crypto engine in mac80211. (cryptmode=1)
- Support inject raw unencrypted frame on monitor interface and use
hardware crypto to encrypt the injected Tx frames. (cryptmode=2)
- Support receive raw hardware decrypted frame with encryption header
on monitor interface. (cryptmode=2)
- Support hybrid local & split MAC mode to support tunneling protocols
such as CAPWAP: Use hardware crypto for BSS in local mode,
and bypass hardware crypto for BSS in split MAC mode.
(cryptmode=2, ath10k_vif nohwcrypt=0 for local mode, =1 for split MAC
mode)
Testing:
Used QCA988x hw 2.0 with firmware-4.bin_10.2.4.48 with
backports-20150424.
All test case tested** with hostapd in both WPA2-PSK-TKIP (11g) and
WPA2-PSK-CCMP(11n/ac). Verified ping and http to google.com works.
**) Need to skip ATH10K_FW_FEATURE_RAW_MODE_SUPPORT check in core.c to
test firmware. After all, none of the existing QCA official firmware
exports that firmware bit yet.
Test Case cryptmode value tested
--------------------------------------------- ----------------------
1. ath10k hardware crypto can encrypt/decrypt 0: PASS
data frames when hostapd config the BSS in 1: Not applicable.
WPA2-PSK-TKIP and WPA2-PSK-CCMP modes. 2: PASS
2. mac80211 software crypto can encrypt/decrypt 0: Not applicable
data frames when hostapd config the BSS in 1: PASS
WPA2-PSK-TKIP and WPA2-PSK-CCMP modes. 2: PASS, when vif
nohwcrypt=1
3. Monitor interface Tx: User application can 0: Not applicable
inject unencrypted raw Tx frames to monitor 1: PASS (mac80211)
interface for mac80211 or hardware to encrypt 2: PASS (hardware)
the frames.
4. Monitor interface Rx: mac80211 software crypto 0: Not applicable
engine can decrypt received TKIP/CCMP frames. 1: PASS
User application see decrypted frames. 2: PASS, when vif
nohwcrypt=1
5. CAPWAP-like local and split MAC datapath 0: Not applicable
tunneling: Setup BSS1=Local MAC mode on wlan0, 1: Not applicable
BSS2=Split MAC mode on wlan0_monitor interface. 2: PASS
Test BSS1 data frames can be encrypted and
decrypted by ath10k hardware crypto engine
while BSS2 data frames can skip both hardware &
kernel mac80211 crypto engines via monitor
interface to the user application fot tunneling.
