Wpad 802.11w no longer working in trunk?

Installing and Using OpenWrt

Not sure if it will mean anything, but removing ieee80211w from the config the radios will start normally with the following log messages:

Compiled using Ubuntu 17.04 x64 and fresh pull of source.git. ieee80211w option continues to cause the radios to not start on WNDR3800. Same error message as in previous logs.

12

Compiled using the same Ubuntu 17.04 box and this time with a fresh pull from the libreCMC git (they re-based off LEDE 17.01) and ieee80211w works fine again on my WNDR3800.

https://bugs.lede-project.org/index.php?do=details&task_id=898

have you tried using hostapd instead?

14

I have same problem on wzr-hp-ag300h, builded on Ubuntu 17.04 x64, snapshot r5025.
When 80211w option removed, everything work well.

Ok, the 11W setting is supposed to be enabled by passing a -DCONFIG_IEEE80211W cflag:
https://github.com/lede-project/source/blame/master/package/network/services/hostapd/Makefile#L75

This should be working fine, if it wasn't for some checks in hostapd's makefiles:
http://w1.fi/cgit/hostap/tree/hostapd/Makefile#n286
Because the makefile doesn't know about cflags and will only care about the contents of the ".config"
which as you can see here:

disables the symbol - (it's commented out so the =y does nothing. + check out the git blame history of the 11W line there.)

Can you edit the hostapd-full.config file (remove the leading #) in your repository, recompile wpad and install the new package?

16

Yep.
root@AG300H:~# opkg list-installed |grep hostapd
hostapd-common - 2017-08-24-c2d4f2eb-1
root@AG300H:~# opkg list-installed |grep wpad
wpad - 2017-08-24-c2d4f2eb-1

17

Oops, I think I accidentally edited the previous reply, instead of making a new one.
Please see: Wpad 802.11w no longer working in trunk?

18

Hmm. That option in hostapd-full.config did not actually change recently, but instead wpa_supplicant-full.config did recently change due to this commit ( cc @stintel ):
https://git.lede-project.org/?p=source.git;a=commitdiff;h=65113799d734d4f6a2cf10f9d704a94b71340fbe

Commented CONFIG_IEEE80211W=y flag because it is
set in the Makefile, only if the driver supports it.

Removed NEED_80211_COMMON flag because it is not part
of config file, it is set by the hostapd upstream Makefile.

The curious part here is why this would affect only some users.

19

If I had to guess, it's probably because of

disabling CONFIG_WPS. But we won't know, unless someone reverts it and tests whenever ieee80211w=1 does work or not.

20

I'm edit hostapd-full.config and/or wpa_supplicant-full.config, recompiled&install but still not work.

The problem has been reported to the Mailing-List.

Apparently, the issue started with:

mac80211: update to backports-4.14-rc2"

Let's see how this will play out.

22

What does WPS has to do with ieee80211w?
I think the problem is the newer version of hostapd

23

Nothing directly. But the CONFIG_WPS did set the NEED_SHA256 dependency in src/hostapd/Makefile (which CONFIG_IEEE80211W needs). Without CONFIG_WPS, this is no longer the case. But other options set it as well,
with any luck something else in the hostapd-full.config needs it too and sets it.

But If this error can really be traced to the the backports-4.14-rc2 patch, you could also try if installing the kmod-cmac module helps. (Note: the module will need to be loaded / (or you reboot the router). I know that mac80211 can request missing cipher modules at runtime and that this is working on a debian system with udev / systemd. But I haven't
verified that procd does it too ).

24

But in my commit i removed CONFIG_WPS2, not CONFIG_WPS...

I'm going to test the older hostapd version

25

Ok, just tested with older version of hostapd (2016-12-19) and it's NOT working.
So the problem may be really related to backports-4.14-rc2.

26

Felix has posted RFT on the mailing-list.

27

For me it's working again after this commit
https://github.com/lede-project/source/commit/609208597b6d18b0c1730f34685db73c859aa492

28

But now I have another problem LOL
The txpower now is alway at minimum...
With iwinfo phy0 txpower
i receive:

   0 dBm (   1 mW)
   1 dBm (   1 mW)
   2 dBm (   1 mW)
*  3 dBm (   1 mW)
   4 dBm (   2 mW)
   5 dBm (   3 mW)
   6 dBm (   3 mW)
   7 dBm (   5 mW)
   8 dBm (   6 mW)
   9 dBm (   7 mW)
  10 dBm (  10 mW)
  11 dBm (  12 mW)
  12 dBm (  15 mW)
  13 dBm (  19 mW)
  14 dBm (  25 mW)
  15 dBm (  31 mW)
  16 dBm (  39 mW)
  17 dBm (  50 mW)
  18 dBm (  63 mW)
  19 dBm (  79 mW)
  20 dBm ( 100 mW)
  21 dBm ( 125 mW)

Also if I try with iw phy phy0 set txpower fixed 1500 nothing changes

29

Well, you know what to do: Report your findings to the Mailing-List :wink: .
