Topic: BB with NCM based 4g/lte DHCP not functioning

The content of this topic has been archived on 1 May 2018. Unfortunately there are posts – most likely complete pages – missing.

I can use tcpdump to grab more data.  Maybe this will help, but it all seems pretty normal to me.

This is from running on BB with the FLAG_SEND_ZLP compiled into cdc.ncm.c.

I also sent you a private email, not sure if you received.  Thanks again for the help with this.

I added some debug messages to cdc_ncm_rx_fixup and cdc_ncm_tx_fixup  in the cdc_ncm.c file to see if sheds any light.

It does not appear that cdc_ncm_rx_fixup is ever called.  Which implies (I think) nothing is coming back from the USB (DHCP) calls.  Unless the USB RX is failing somewhere earlier in the stack, correct?

Does this lean more to an issue with the TX packet, or the RX packet?


Running with standard BB NCM files (no ZLP flag and the padding code left intact), I added a debug message to the cdc_ncm_tx_fixup call, at the enty into the function, and one at the end of the function.

    printk(KERN_INFO KBUILD_MODNAME
            ": TX_FIXUP return: skb_out: %p\n", skb_out);

Does this provide any insight?  I doubt it.

I am trying to output the sk_buff content from the tx_fixup function.  Will try to add that here also.

Here is the output of the skb from the cdc_ncm_tx_fixup function.

I have before the call to cdc_ncm_fill_tx_frame and after the call logged.

I am not sure how to take this though and figure out what is "wrong".  Any suggestions on next steps?

Here is the debug placement:

cdc_ncm_tx_fixup(struct usbnet *dev, struct sk_buff *skb, gfp_t flags)
{
    struct sk_buff *skb_out;
    struct cdc_ncm_ctx *ctx = (struct cdc_ncm_ctx *)dev->data[0];

        printk(KERN_INFO KBUILD_MODNAME
            ": TX_FIXUP entry: skb: %p\n", skb);
            
    skb_print_bits("TX_FIXUP Entry (skb)", skb, 0, 0);

...

    spin_lock_bh(&ctx->mtx);
    skb_out = cdc_ncm_fill_tx_frame(ctx, skb, cpu_to_le32(USB_CDC_NCM_NDP16_NOCRC_SIGN));
    spin_unlock_bh(&ctx->mtx);
    
    skb_print_bits("TX_FIXUP return (skb_out)", skb_out, 0, 400);
    
    printk(KERN_INFO KBUILD_MODNAME
            ": TX_FIXUP return: skb_out: %p\n", skb_out);
    
    return skb_out;


Here is the ouput:

Hi,

I think I just run into this myself with my E3372. No DHCP reply on CC as well as Fedora 21. However DHCP works fine on Fedora 20 until 3.15. 3.16 is the first kernel version DHCP doesn't work anymore. So this looks like a kernel driver issue to me.

Will try to dig deeper in the next days.

Oh, and another bug report I found earlier: https://bugzilla.redhat.com/show_bug.cgi?id=1214165

In my research there is some issue in 3.16, and it has been fixed in a later release.  Don't have the link handy right now, sorry.  Google should find it.

My issue is different, as it doesn't work on 3.10, or 3.18 (which it should be fixed in).

I wanted to add to this thread as we have gotten the ME936 LTE module to work correctly (Thank you Bjorn!) using the NCM interface on Barrier Breaker.

There were 2 issues preventing it from working.

1) ARP is not supported on the card, so the interface must be brorught up with the '-arp' argument:  ifconfig wwan0 -arp up

2) DHCP is not supported on the card so the ncm.sh script had to be modified to support pulling the DHCP information from the serial interface and setting the IP/Mask/GW/DNS in the script as the dhcp service calls will never work.   The AT command "at^dhcp?" will return DHCP information:

<clientip>,<netmask>,<gate>,<dhcp>,<pDNS>,<sDNS>,<max_rx_data>,<max_tx_data>



Once these two items were addressed, the card works correctly.

Can you share your modifications please?

I added this code to the ncm.sh script:

Before the connect command is executed via gcom:

# Make sure the interface is started before we connect.  Turn ARP off for ME936 card.
ifconfig "$ifname" -arp up

I added this code after the connection was made to retrieve DHCP from the AT commant, and removed the existing code that attempted to use udhcp to retrieve the DHCP information.  Please note this has only been tested with the ME936 and may not generically work with other adapters.

DHCP="$(gcom -d "$device" -s /etc/gcom/getdhcp.gcom)"

# Extract IP values from AT command
IPLOCAL=${DHCP:20:8}
IPMASK=${DHCP:31:8}
IPGW=${DHCP:42:8}

# Convert IP values to decimal form

echo "local IP address: $IPLOCAL"
echo "Netmask: $IPMASK"
echo "Gateway: $IPGW"
echo "Primary DNS: $DNS1"
echo "Secondary DNS: $DNS2"

# Override GW with IPLOCAL
IPGW=$IPLOCAL

proto_init_update "$ifname" 1

# IPMASK is invalid, just use 255.255.255.255 (32)
[ -n "$IPLOCAL" ] && proto_add_ipv4_address "$IPLOCAL" 32 "" ""
[ -n "$IPGW" ] && proto_add_ipv4_route 0.0.0.0 0 "$IPGW"
[ -n "$DNS1" ] && proto_add_dns_server "$DNS1"
[ -n "$DNS2" -a "$DNS1" != "$DNS2" ] && proto_add_dns_server "$DNS2"

proto_send_update "$interface"

You will also need to add a gcom script to execute the AT^DHCP command and retrieve the result.

Thanks.

I'm running CHAOS CALMER (15.05-rc2, r45918) with no modifications on a 1043nd

Any idea why I'm not getting a DHCP response, and what else I could try?

It looks like the modem is not connecting to the provider.  The cdc_ncm driver should get notified of the connection and the output some lines into the log.

To further debug, I would try doing everything by hand, step by step, and see if you can get any further.  But I don't know anything about that modem......

If the AT^DHCP command does not work, I would think the modem supports DHCP in which case udhcp should work, but I think your issue is before that in that no connection is actually being established.

I assume the SIM is active and works in another device?  And the APN is correct?

This is what the log should be (on BB) after the connect command:

Wed Jun 24 07:51:17 2015 daemon.notice netifd: wan2 (1833): sending -> AT^NDISDUP=1,1,""
Wed Jun 24 07:51:17 2015 kern.info kernel: [   76.860000] cdc_ncm: wwan0: network connection: connected
Wed Jun 24 07:51:17 2015 kern.info kernel: [   76.860000] IPv6: ADDRCONF(NETDEV_CHANGE): wwan0: link becomes ready
Wed Jun 24 07:51:17 2015 kern.info kernel: [   76.870000] cdc_ncm: wwan0: 100 mbit/s downlink 50 mbit/s uplink

Yes the card is working (it's a second card to my contract), verified on a phone. The APN matches the one on the phone.

When doing the steps manually, it looks good:

AT^NDISDUP=1,1,"internet.telekom"
OK
^NDISSTAT:1,,,"IPV4"
^NDISSTAT:0,50,,"IPV6"
AT+COPS?
+COPS: 0,0,"Telekom.de“,7

But the wwan0 interface is not getting an IP.

I found some people having identical issues: https://bugs.archlinux.org/task/39021
Should be resolved with my kernel however, but no joy.

Anyway I gave up, returned the device. Now I have a Vodafone K5150 (Huawei E3276) which has an MBIM interface and works on the first try. Thanks, blogic, for the hint!

Some news here? I have one E3276s-500:
Manufacturer: huawei
Model: E3276
Revision: 21.260.05.00.255

and same problem with CCrc3, get a interface up but not get IP. uDHCP failed.

Try the AT^DHCP command to see if you can grab DHCP info manually.

The latest official CC doesn't fix the issue.

The fix in https://dev.openwrt.org/ticket/20103 is the correct one, but it hasn't been applied in CC.
I'm using the latest trunk and that works ok. (Sort of, I still get wwan0: kevent 12 may have been dropped and I don't get a connection message when a connection is made successfully)

The following line should be present in dmesg if the fix is present:

huawei_cdc_ncm 2-1:1.2: NDP will be placed at end of frame for this device.

My 3 cents. I have Huawei E3372 HiLink which was flashed to 21.180.01.00.00 firmware. lsusb now reports

12d1:1506 Huawei Technologies Co., Ltd. Modem/Networkcard,

which is equivalent to Huawei E398. Modem is handled correctly by Kubuntu 14.04 as well as 16.04. Under OpenWrt 15.05.1 (CC) the modem does not work correctly, as the patch of Enrico Mioso:

190-cdc_ncm_add_support_for_moving_ndp_to_end_of_ncm_frame.patch

did not enter this release. After a switch to the development snapshot of 2016/09/12 I got my modem working, but without DHCP. Modem connects using

AT^NDISDUP

command and reports valid IP settings by

AT^DHCP.

Manual configuration of wan0 interface and routing tables makes the connection operable and quite fast (28Mbps). I use

h_t_t_p_s://github.com/zabbius/smarthome/tree/master/openwrt/,

to connect to my ISP so the application of JohnV scripts should be straightforwad (ty John). Nevertheless, the problem with DHCP in cdc_ncm  (?) was still not solved until 2016/09/12.
