HT40 after associated" break iwlagn driver for Intel Corporation
Centrino Ultimate-N 6300 (rev 35) on my Thinkpad t510. I still can

Hi,
The patch fixes the following bug:
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2326
If the patch introduces a regression for you, then the problem needs to be
investigated further. Reverting the patch will reintroduce an already fixed
problem for others.
Cheers,
- Udo

Hi,
this is pretty mean regression for the stable kernel. You may the fix
only for cards, which need it and not for all of them.

Could you elaborate more on the failure case and setup. this patch is to
address HT40 related problem which cause the iwlwifi firmware crash.

Hi,
i haven't experienced firmware crushes, but after that commit i don't
get any networking with my wlan card. I added some lspci and dmesg
output to the patch. There was no strange output in my dmesg. dhcpcd
says in logs, that carrier lost after about 30 seconds. How can i
reproduce the HT40 bug?
Regards,
Andrej

Hi,
Glad to hear it works for you now. In the patch, the following piece of code
+ if ((iwl_is_associated_ctx(ctx) &&
+ !ctx->ht.is_40mhz) ||
+ !iwl_is_associated_ctx(ctx))
can be simplified to:
if (!iwl_is_associated_ctx(ctx) || !ctx->ht.is_40mhz)
Cheers,

I had a problem with 3.1.5 (3.1.4 was fine) and current Linus git
where I was able to associate with my AP (5GHz) but only icmp was
working and while trying to ssh then all packets (including icmp ones)
started to be dropped.
My card is 5350 AGN [Echo Peak] and this patch makes things working
for me on top of current Linus git, too.
