Netd error after JB porting

[Fabio Fumi]

We're approaching a porting to JB for a Renesas-based tablet. Progress here:

https://groups.google.com/forum/#!forum/renesas-emev-osp

The main issue we're hitting is a boot-loop, with the following in the logcat:

I/Netd    ( 2440): Netd 1.0 starting
E/BandwidthController( 2440): runIptablesCmd(): failed /system/bin/iptables -N bw_INPUT res=768

E/NetdConnector(  675): Error in NativeDaemonConnector: java.io.IOException: No such file or directory

I've found several similar issues on the net, all pointing in away or another to the kernel configuration of NETFILTER (and sub-options). At present I have these set:

$ grep NF_IP .config | grep -v "^#"
CONFIG_IP_NF_IPTABLES=y

$ grep NET .config | grep -v "^#"
CONFIG_NET=y
CONFIG_INET=y
CONFIG_ANDROID_PARANOID_

NETWORK=y
CONFIG_NET_ACTIVITY_STATS=y
CONFIG_NETFILTER=y
CONFIG_NETFILTER_ADVANCED=y
CONFIG_NETFILTER_XTABLES=y
CONFIG_NETDEVICES=y
CONFIG_NET_ETHERNET=y
CONFIG_NETWORK_FILESYSTEMS=y

but looks like they're not enough, as errors are still there. Probably in the init.rc something to enable? I'm stuck !

Do we have any reference about the minimal kernel config for JB? Note - this is a 2.6.35 kernel.

 thanks in advance for any help

MDnsDS (btw - what is it?) doesn't report errors, but debug messages. Infact, I had found some fixes to the init.rc, which I've already included.

What I miss I think is several kernel options, in the "netfilter" and "IPtables" area, which I'm not sure they're all even exist in pre-3.x kernel. E.g I found this interesting post:

 http://android.modaco.com/topic/330834-advent-vega-kernel-source-code-now-available/page__st__820

saying we need (at least) to back-port to a 2.6.x kernel the " porting the quota2 netfilter " from a 3.x one... That's what I'm trying now, using some AOSP 3.x kernel.

Any suggestion which one to use, for a new device, as a starting point?

I only wonder if there's any "minimal" configuration and if we really need a 3.x kernel for JB.

Sounds like a ramdisk issue. Check and make sure your ramdisk (mainly init.rc) has the necessary parts for the mdns service. You can see here that there are additions to the netd service (these mdns services weren't in Android versions before Jellybean) that have mdns added to it and there is also an mdns service as well at the bottom of the init.rc I linked to earlier. Add those two parts to the init.rc and see if that resolves the issue.

Re-posting, correcting a few typo...

[Fabio Fumi]

I've enabled a number of config options in my 2.6.35 kernel,about the NETFILTER, IP_NF, IPV6 and IP6_NF features, taking this one as an example:

https://android.googlesource.com/kernel/tegra/+/8dd2eab82ac83ffbc1936b7b7d5a8971ce2ad74b/arch/arm/configs/tegra3_android_defconfig

(this is the 3.1 android tegra kernel)

Final result is the same (a boot-loop) but return codes from the iptables and ip6tables are different. Used to be "res=768", now it's "res=256":

iptables v1.4.11.1: can't initialize iptables table `raw': Permission denied
Perhaps iptables or your kernel needs to be upgraded.

3|shell@android:/ $ /system/bin/iptables -A bw_INPUT -m owner --socket-exists
Could not open socket to kernel: Permission denied

In both cases a "Permission denied" error is returned now.

Any idea what could be missing now?

[Fabio Fumi]

This one:

E/BandwidthController( 1097): runIptablesCmd(): failed /system/bin/iptables -t raw -N bw_raw_PREROUTING res=256

comes from this call:

    sockfd = socket(TC_AF, SOCK_RAW, IPPROTO_RAW);

failing with:

       EACCES Permission to create a socket of the specified type and/or protocol is denied.

Anyone knows what does that mean?
Where's this permission defined?

I have used Johnatan's suggestion, so my init.rc now includes:

service netd /system/bin/netd
    class main
    socket netd stream 0660 root system
    socket dnsproxyd stream 0660 root inet

service mdnsd /system/bin/mdnsd
    class main
    user mdnsr
    group inet net_raw
    socket mdnsd stream 0660 mdnsr inet
    disabled
    oneshot

...but same errors are still there in logcat.

I've enabled debugging from iptables. Hoping someone here can read at it...

Looks like I managed to make it go this time !

I had to add this section at the end of init.rc:

service mdnsd /system/bin/mdnsd
    class main
    user mdnsr
    group inet net_raw
    socket mdnsd stream 0660 mdnsr inet
    disabled
    oneshot

Thanks Johnatan for the pointers!

+    class main
+    user mdnsr
+    group inet net_raw
+    socket mdnsd stream 0660 mdnsr inet

here:https://groups.google.com/forum/#!forum/renesas-emev-ospThe main issue

we're hitting is a boot-loop, with the following in the logcat:I/Netd    (

found several similar issues on the net, all pointing in away or another to

the init.rc something to enable? I'm stuck !Do we have any reference about

the minimal kernel config for JB? Note - this is a 2.6.35 kernel. thanks in
advance for any help Fabio

I managed to correct this error by add one line in the service 'netd'
such as

service netd /system/bin/netd
class main
socket netd stream 0660 root system
socket dnsproxyd stream 0660 root inet

socket mdns stream 0660 root system
the last line was what I added following the default init.rc file in
system/core/rootdir/
