Problem Description:
I can't get an IP address via DHCP with my wireless connection. I have an Intel Wireless 4965 card and I use WPA personal with AES encryption. After a git-bisect run, it seems the first bad commit is the following:

net_sched: Add size table for qdiscs
Add size table functions for qdiscs and calculate packet size in qdisc_enqueue().
Based on patch by Patrick McHardy
http://marc.info/?l=linux-netdev&m=115201979221729&w=2

A whole pile of networking patches went into mainline about 12 hours ago, one of which might have fixed this. Can you please test 2.6.26-git10 once it has appeared and let us know the result?

Thanks.

Thanks.

The problem still occurs with 2.6.26-git-10. But if I use a static address instead of DHCP, the connection work. DHCP also work with my ethernet card (a Marvell yukon which use the sky2 driver). But DHCP doesn't work with my wireless connection using the iwl4965 driver. As I said, my router offer several time a correct IP adress but it is not accepted by my computer. I don't use traffic shaping (see my iptables rules). Furthermore, the problem still occurs if I disable iptables. Does anybody have an idea to solve the problem ?

Thanks for your help,
François

P.S: why don't you want to use the bugzilla interface ?

P.S: why don't you want to use the bugzilla interface ?

Depends on the subsystem. ACPI is 100% bugzilla-based, net people prefer email, others are in-between.

Plus for recently-occurring bugs it's best to knock them over via email without getting into bugzilla bureaucracy. bugzilla is more appropriate to longer-term bugs.

And when the bug affects multiple subsystems, multiple developers and we don't even know which subsystem introduced it, it is much better to perform the diagnosis and repair via email.

I make a judgement call on each report. Been doing it for a while, don't get too many complaints ;)

I tested myself using dhcpcd 3.2.3 on an ethernet device and it works fine, so this appears to be driver related.

I also noticed that DHCP works without problem with my ethernet card (using the sky2 driver), so there seems to be a problem or conflict with the iwl4965 driver. However, if I use dhclient instead of dhcpcd, I can get an IP adress with DHCP and the DNS servers are correctly written in /etc/resolv.conf. Unfortunately, name resolution doesn't work, even if I can ping the DNS server.

Interesting. Could you post straces of both commands please?

I suppose you wanted to see the output of strace for dhcpcd and dhclient. So I have attached the two files.

OK, thanks for the explanation. But do you have more ideas about the problem ?

I tested myself using dhcpcd 3.2.3 on an ethernet device and it works fine, so this appears to be driver related.
I also noticed that DHCP works without problem with my ethernet card (using the sky2 driver), so there seems to be a problem or conflict with the iwl4965 driver. However, if I use dhclient instead of dhcpcd, I can get an IP adress with DHCP and the DNS servers are correctly written in /etc/resolv.conf. Unfortunately, name resolution doesn't work, even if I can ping the DNS server.
Interesting. Could you post straces of both commands please?

I also send the output of strace for dhcpd under kernel 2.6.26 (where it works correctly). François

Well, no luck, the current -git kernel doesn't boot on my notebook and I don't have time for a bisection currently. Could someone else try to verify/debug this?

net_sched: Add size table for qdiscs

Add size table functions for qdiscs and calculate packet size in qdisc_enqueue().

Based on patch by Patrick McHardy

    http://marc.info/?l=3Dlinux-netdev&m=3D115201979221729&w=3D2

This time, I didn't encounter kernels which didn't compile. So, I didn'= t=20
use git-reset or git-bisect skip.

This time, I didn't encounter kernels which didn't compile. So, I didn't use git-reset or git-bisect skip.

I think I know whats happening (Jussi CCed). That commit introduced a qdisc_skb_cb, which conflicts with the mac80211 usage of skb->cb. mac80211 seems to expect the CB to survive the qdisc layer, which is wrong. One possibility to fix this (or just test my theory) would be to make sure they don't clash by adding the struct ieee80211_tx_info to qdisc_skb_cb->data. Something like this patch.

This time, I didn't encounter kernels which didn't compile. So, I=20 didn't use git-reset or git-bisect skip.
I think I know whats happening (Jussi CCed). That commit introduced a qdisc_skb_cb, which conflicts with the mac80211 usage of skb->cb. mac80211 seems to expect the CB to survive the qdisc layer, which is wrong. One possibility to fix this (or just test my theory) would be to make sure they don't clash by adding the struct ieee80211_tx_info to qdisc_skb_cb->data. Something like this patch.

I tested your last patch. Unfortunately, I get the following compile error:
In file included from net/mac80211/main.c:11:
include/net/mac80211.h: In function ‘IEEE80211_SKB_CB’:
include/net/mac80211.h:347: erreur: size of array ‘type name’ is negative

I was afraid that might happen. This means skb->cb is not large enough to hold both the qdisc and the ieee80211 structs.

Just for testing, changing (include/net/mac80211.h):

#define IEEE80211_TX_INFO_DRIVER_DATA_SIZE \
        (sizeof(((struct sk_buff *)0)->cb) - 8)

#define IEEE80211_TX_INFO_DRIVER_DATA_SIZE \
        (sizeof(((struct sk_buff *)0)->cb) - 12)

might help to get it to compile. If that doesn't work, try -16. --

We can't fit them into the cb together, I don't see a way to shrink ieee80211_tx_info.

Maybe one of the wireless folks can suggest something? Is it really necessary to pass the full struct ieee80211_tx_info through the qdisc layer, or could the struct be split? It needs to find a way to co-exist peacefully with qdiscs' skb->cb usage.

This is another area that got mangled up in the ->select_queue() conversion of the WME bits, but in another aspect this problem existed beforehand as well.

Specifically, when RX packets get requeued out to transmit in the code in net/mac80211/rx.c that resends packets back out the wireless device by setting a bit in the SKB CB then calling dev_queue_xmit().

That's completely illegal :-)

There's a ton of stuff in that structure, I can't see how to make it smaller either. Maybe some bits only matter through the layers of the TX mac80211 stack and thus can be passed as parameters during such processing?

It seems its doing even more illegal things that were also present previously. The ieee80211_master_start_xmit function expects to get a valid IEEE80211_SKB_CB, which means it expects it to survive through the entire qdisc layer. I'm not sure how packets get to the master device from the subifs though, so I might be wrong.

We've discussed that over and over and over and over again, and it's not going to fly since 802.11 throughout assumes that you have a two-address data service to the upper layers.

Besides, making it 802.11 native doesn't help with the control information at all.
