From: Sergey Matyukevich <sergey.matyukevich.os@xxxxxxxxxxxxx> Commit cdeea70f59d0 added wpa_s configuration options allowing HT STBC modifications for RX/TX spatial streams. Add tests to verify overriding of default HT STBC configuration for Tx and Rx spatial streams for hwsim driver. The test flow is straightforward: use wpa_s 'tx_stbc' and 'rx_stbc' configuration options to override default HT Rx/Tx STBC settings and check HT capabilities IEs in ASSOC frames. The following tests have been added: - ap_ht_stbc_disabled make sure that HT Rx/Tx STBC is disabled by default for hwsim driver - ap_ht_stbc_tx make sure that Tx STBC can be properly enabled for hwsim driver using wpa_s 'tx_stbc' configuration option - ap_ht_stbc_rx make sure that Tx STBC can be properly enabled for hwsim driver using wpa_s 'tx_stbc' configuration option Signed-off-by: Sergey Matyukevich <sergey.matyukevich.os@xxxxxxxxxxxxx> --- This patch depends on the following hwsim driver change: https://patchwork.kernel.org/patch/10752835/ tests/hwsim/test_ap_ht.py | 68 +++++++++++++++++++++++++++++++++++---- 1 file changed, 62 insertions(+), 6 deletions(-) diff --git a/tests/hwsim/test_ap_ht.py b/tests/hwsim/test_ap_ht.py index e6f6502f4..bd452d5ba 100644 --- a/tests/hwsim/test_ap_ht.py +++ b/tests/hwsim/test_ap_ht.py @@ -9,11 +9,13 @@ import time import logging logger = logging.getLogger() import struct +import os import hostapd from utils import HwsimSkip, alloc_fail, parse_ie import hwsim_utils from test_ap_csa import csa_supported +from tshark import run_tshark def clear_scan_cache(apdev): ifname = apdev['ifname'] @@ -851,16 +853,70 @@ def test_ap_require_ht(dev, apdev): ampdu_density="1", disable_ht40="1", disable_sgi="1", disable_ldpc="1", rx_stbc="2", tx_stbc="1") -def test_ap_ht_stbc(dev, apdev): - """HT STBC overrides""" +def test_ap_ht_stbc_disabled(dev, apdev, p): + """HT STBC overrides: RX/TX STBC is disabled by default""" params = { "ssid": "ht" } hapd = hostapd.add_ap(apdev[0], params) dev[0].connect("ht", key_mgmt="NONE", scan_freq="2412") - dev[1].connect("ht", key_mgmt="NONE", scan_freq="2412", - rx_stbc="0", tx_stbc="0") - dev[2].connect("ht", key_mgmt="NONE", scan_freq="2412", - rx_stbc="1", tx_stbc="1") + dev[1].connect("ht", key_mgmt="NONE", scan_freq="2412", tx_stbc="-1", rx_stbc="-1") + dev[2].connect("ht", key_mgmt="NONE", scan_freq="2412", tx_stbc="0", rx_stbc="0") + + capfile = os.path.join(p['logdir'], "hwsim0.pcapng") + filt = "wlan.sa==%s && wlan.fc.type_subtype == 0x0" + + for sta in [0, 1, 2]: + res = run_tshark(capfile, filt % dev[sta].own_addr(), [ "wlan.ht.capabilities.txstbc" ]) + res = res.splitlines() + res = [int(x) for x in res] + for tx_stbc in res: + if tx_stbc != 0: + raise Exception("STA[%d]: TX STBC should be disabled, actual value: %d" % (sta, tx_stbc)) + + res = run_tshark(capfile, filt % dev[sta].own_addr(), [ "wlan.ht.capabilities.rxstbc" ]) + res = res.splitlines() + res = [int(x, 16) for x in res] + for rx_stbc in res: + if rx_stbc != 0: + raise Exception("STA[%d]: RX STBC should be disabled, actual value: %d" % (sta, rx_stbc)) + +def test_ap_ht_stbc_tx(dev, apdev, p): + """HT STBC overrides: verify TX STBC configuration""" + params = { "ssid": "ht" } + hapd = hostapd.add_ap(apdev[0], params) + + dev[0].connect("ht", key_mgmt="NONE", scan_freq="2412", tx_stbc="1") + + capfile = os.path.join(p['logdir'], "hwsim0.pcapng") + filt = "wlan.sa==%s && wlan.fc.type_subtype == 0x0" + + res = run_tshark(capfile, filt % dev[0].own_addr(), [ "wlan.ht.capabilities.txstbc" ]) + res = res.splitlines() + res = [int(x) for x in res] + for tx_stbc in res: + if tx_stbc != 1: + raise Exception("TX STBC should be enabled, actual value: %d" % tx_stbc) + +def test_ap_ht_stbc_rx(dev, apdev, p): + """HT STBC overrides: verify RX STBC configuration""" + params = { "ssid": "ht" } + hapd = hostapd.add_ap(apdev[0], params) + + dev[0].connect("ht", key_mgmt="NONE", scan_freq="2412", rx_stbc="1") + dev[1].connect("ht", key_mgmt="NONE", scan_freq="2412", rx_stbc="2") + dev[2].connect("ht", key_mgmt="NONE", scan_freq="2412", rx_stbc="3") + + capfile = os.path.join(p['logdir'], "hwsim0.pcapng") + filt = "wlan.sa==%s && wlan.fc.type_subtype == 0x0" + + for sta in [0, 1, 2]: + res = run_tshark(capfile, filt % dev[sta].own_addr(), [ "wlan.ht.capabilities.rxstbc" ]) + res = res.splitlines() + res = [int(x, 16) for x in res] + expected = sta + 1 + for actual in res: + if actual != expected: + raise Exception("STA[%d]: RX STBC expected %d, actual %d" % (sta, expected, actual)) @remote_compatible def test_ap_require_ht_limited_rates(dev, apdev): -- 2.20.1 _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
