With this patch applied to 2.6.33-rc3 kernel crashes at boot...
I have a iwl4965 connecting to a wpa2-psk encrypted network, arch is
x86_64, distro Mandriva Linux and the kernel has preempt enabled.
Am I only missing some patches, or did I hit a real bug ?
It'd help if you said what crashes and how since nobody else seems to be
having that particular problem with this patch.
I have an idea.
The patch adds the following chunk of code:
+ if (!sta&& ra&& !is_multicast_ether_addr(ra)) {
+ sta = sta_info_get(sdata, ra);
+ if (sta)
+ sta_flags = get_sta_flags(sta);
In wireless-testing, sta_info_get takes sdata as first argument, in
2.6.33-rc3 it expects a pointer to local. This should have emitted a
compiler warning... I saw the same thing when applying the patch to an
older compat-wireless snapshot.
Oh so it did (unfortunately the kernel build does not honour LC_ALL=C
anymore, so the warning is in swedish):
net/mac80211/wme.c: I funktion "ieee80211_select_queue":
net/mac80211/wme.c:99: varning: skickar argument 1 till "sta_info_get" fr?n inkompatibel pekartyp
