 |
|
Hi guys,
I'm facing a problem very similar to this (https://forums.gentoo.org/viewtopic-t-1063542.html). I have a hardened kernel with grsecurity and pax disabled and my wireless driver seem to crash every time I try to connect to an AP. I'm able to scan and negotiate a connection but can't finish it. Any help/guidance is appreciated. Here is the dmesg:

Amity88 ...
it seems to be a somewhat different issue to that linked, theirs happens on suspend/wake while yours seems to be an issue with CFG80211_WEXT. I don't have a broadcom chip/card but do these actually require WEXT? Are you passing -Dnl80211 to wpa_supplicant? If not you should try doing so, and/or disabling CFG80211_WEXT in the kernel (assuming the tools, and driver, are using NL80211 rather than WEXT). Otherwise, it might be worth enabling debug, and logging, on wpa_supplicant, eg:
| /etc/conf.d/net: | | wpa_supplicant_wlan0="-Dnl80211 -dd -f /var/log/wpa_supplicant.log" |
or, if you're using wpa_supplicant, or dhcpcd, to provide 'net'
| /etc/conf.d/wpa_supplicant: | | wpa_supplicant_args="-Dnl80211 -dd -f /var/log/wpa_supplicant.log" |
If this is in fact an issue with powersave then you might try disabling powersave on the card (requires net-wireless/iw) ...
| Code: | | # iw dev wlan0 set power_save off |
You didn't mention what you're using as a supplicant (I'm assuming wpa_supplicant), or what other tools are involved, or firmware. These may play some role as some tools (net-wireless/wireless-tools for instance) require (the now obsolete) WEXT, whereas net-wireless/wpa_supplicant, net-wireless/iw, etc, use NL80211.

Khay,
Thanks for pointing that out., my problem got solved It was indeed due to WEXT. I actually had two problems, this was one. Then WICD kept crashing wpa_supplicant, I got rid of it and installed networkmanager.
Note:
For anyone using Gentoo Hardened with PAX enabled. Proprietary WL will work but disable KERNEXEC, RAP and don't restrict kmem access.

Amity88 ... you're welcome. As for wicd, this is one of those tools that uses WEXT exclusively, so by disabling CFG80211_WEXT you would need to switch to some other tool. BTW, wpa_supplicant also has wpa_gui (if USE="qt5" is set) if you were looking for something other than NetworkManager.
