[OpenWrt-Devel] [PATCH] start selected services after block mount
This patch adds /etc/hotplug.d/block/60-services that will look for "service" entries in /etc/config/fstab against a given mount and start them once the mount has been completed by the hotplug system. This is to solve the problem of usb devices being mounted after most of the rc system has completed, therefore any services that are intended to write to a mounted filesystem either fail or end up writing to the mount point prior to the mount.An example config:config 'mount' option 'enabled' '1' option 'device' '/dev/sda1' option 'target' '/site' option 'fstype' 'ext4' option 'options' 'rw,noatime' list 'service' 'syslog-ng' list 'service' 'collectd'Signed-off-by: Lee Essen block_mount_svcs.patch Description: Binary data ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
[OpenWrt-Devel] Resend: [PATCH] start selected services after block mount
Is there any interest in this?Is it better packaged separately?Also, as a side note, it does present another challenge ... all packages included in the image are enabled by default, this means these things would startup automatically the first time around could be enhanced to include a config string containing those packages not to auto-enable. I'm happy to implement, but if nobody is interested then I'll just keep it to my local repository.Thanks,Lee.Begin forwarded message:From: Lee Essen <lee.es...@nowonline.co.uk>Date: 18 February 2011 08:48:00 GMTTo: openwrt-devel@lists.openwrt.orgSubject: [PATCH] start selected services after block mountThis patch adds /etc/hotplug.d/block/60-services that will look for "service" entries in /etc/config/fstab against a given mount and start them once the mount has been completed by the hotplug system.

[OpenWrt-Devel] [PATCH] ltq_dsl_app support for taking pppoa link up and down
Hi, The attached patch adds a "notify" script to the dsl_cpe_control app to bring the relevant pppoa interface up (or down) whenever there is a line status change. As far as I can tell the existing hotplug mechanism doesn't work for non-br2684 based systems as there is no nas0 interface created, and hence no hotplug event ... so the ppp link stays down until you manually start it, people may be surviving by having an erroneous bridge configured (which seems to be the default), but clearly this isn't the right behaviour. The patch largely replicates the code from the atm hotplug script (with the addition of support for the link going down.)

If this script didn't look for pppoa interfaces then it would try to bring up any 'down' interfaces when the DSL line came up, and more worryingly it would take every interface down when the link went down. My understanding is that you either use a br2684 bridge (for pppoe based DSL providers) or pppoa for native pppoa DSL providers (although I've no experience of the bridge option so I am making some assumptions.) In the bridge case the ppp link comes up as part of the hotplug mechanism, but for pppoa you need to trigger it as per the patch. So I'm not sure why you would look at non pppoa interfaces? In fact the code is mostly copied from the hotplug atm script to ensure the behaviour is as similar as possible. > + if [ "$DSL_INTERFACE_STATUS" = "UP" ]; then > + if [ "$proto" = "pppoa" ] && [ "$up" != 1 ] && [ "$auto" = 1 > ]; then > + found=1 > + ( sleep 1; ifup "$ifc" ) & > + fi > + else > + if [ "$proto" = "pppoa" ] && [ "$up" = 1 ] && [ "$auto" = 1 > ]; then > + found=1 > + ( sleep 1; ifdown "$ifc" ) & > + fi > + fi > +done > > This is the part of the patch I'm refering to.

[OpenWrt-Devel] DSL support and luci integration
Hi,
I've been using trunk on a Buffalo WBMR-HP-G300H ADSL router with great
success, so I've been looking at the existing DSL support and am keen to
help out getting it better integrated.
I'm conscious that there are likely to be a number of different DSL
devices needing support and have been thinking about a way to have
relatively standard support in LuCI but with flexibility in
implementation.
I have put together some patches to start doing this, but thought it
best to check the concepts before getting too far ... also I don't know
if anyone else is working on this or if other ideas have been discussed.
So basically:
A single "control" script that is shipped as part of the relevant
driver (or app) for the device. For me, this is the lantiq one.
The control script (my suggestion is: /etc/init.d/dsl_control) would
be responsible for the normal start and stop as any rc script would be.
But also ... the control script can be used to get the DSL status,
either in human readable form, or in a standard form parsable by Luci.
In this way any DSL implementation need only provide basic start, stop
and status information and then it could easily appear in LuCI to
provide line status, speed and noise information without any hardware
specific detail in LuCI.
Just by way of example:
root@OpenWrt:~# /etc/init.d/dsl_control status
Line State: UP [0x801: showtime_tc_sync]
Data Rate: 4.064 Mb/s / 448 Kb/s
Line Attenuation: 49.0dB / 26.5dB
Noise Margin: 12.2dB / 25.0dB
Or, the LuCI compatible version ... I went for a "loadstring" approach
that returned a lua table:
root@OpenWrt:~# /etc/init.d/dsl_control luastat
local dsl={}
dsl.line_state_num=0x801
dsl.line_state_detail="showtime_tc_sync"
dsl.line_state="UP"
dsl.data_rate_down=4064000
dsl.data_rate_up=448000
dsl.data_rate_down_s="4.064 Mb"
dsl.data_rate_up_s="448 Kb"
dsl.line_attenuation_down=49.0
dsl.line_attenuation_up=26.5
dsl.noise_margin_down=12.3
dsl.noise_margin_up=25.0
return dsl
I've also implemented the basic summary in the LuCI admin overview page
which looks pretty nice, updates regularly (you can see the noise margin
changing) and doesn't seem to place much load on the system.
There's a bit more to do, it currently doesn't actually check the
daemon is running etc, also I think a "start_available" and
"stop_available" variable might be a nice way to control whether LuCI
should allow start and stop buttons ... possible on the network admin
page?
Anyway ... just a few ideas, interested in thoughts, I can post the
current patches if there's interest, or happy to explore other ideas if
I'm way off the mark.
Cheers,
Lee.

Ok, these aren't in the right format for a couple of reasons (namely that I
haven't got a LuCI tree checked out yet, and that I'm still working on the main
script and haven't put it back into the main tree), but hopefully this will
give you a feel for what I'm talking about….
Firstly the main dsl_control script (/etc/init.d/dsl_control) … used to
stop/start and provide hardware specific stats, this is still work in progress,
I'll tidy it up and add more functionality (and error checking) over the next
couple of days, and build a proper patch...

There is an ioctl interface, which also works without the daemon running, which I did consider, but my thought was that this would require an extra binary to maintain (unless there's a simple lua ioctl interface, but I couldn't find one) and would have a lot less transparency than a script -- but I'm happy to knock something up to make use of this if it's considered a better approach.

Re: [OpenWrt-Devel] DSL support and luci integration
Ok, with a bit of further investigation, netlink doesn't actually seem too difficult … is there a process for registering new support (i.e. NETLINK_DSL) or is there some other way to do this? Could something else be re-used? I'm happy to have a go at a sample implementation, but I'm completely new to netlink, so a little help and a few pointers would be great. Cheers, Lee.

[OpenWrt-Devel] [PATCH 1/2] Initial DSL framework for Lantiq
Hi,
I think I've got my initial concept for DSL support to a point where it's quite
functional now and ready for a bit more extensive testing. I will look at
netlink as discussed, but I think that will take some time, so I think this
would serve as a good interim solution (some of it is valid with a netlink
solution anyway.)
So this proposes a very simple script based framework (which is used by LuCI)
and provides an implementation for the Lantiq driver.
The patch is in two parts, this one contains the non-LuCI bits, the next one
provides support for DSL in LuCI with an overview status in the admin_status
page and a extra DSL tab on the network admin section which shows similar data
and allows you to start and start the daemon.
So the non-luci bits:
- Removed ifx_cpe_control_init.sh (the old init script)
- Created dsl_control (/etc/init.d)
- tidied up start and stop
- stop calls dsl_notify before killing daemon
- has status and lucistat options to provide detail
- copes with daemon not running situation
- Updated package makefile to use new init script and to build cli support
- Provide a dsl_notify.sh script to cope with line up/down events
The patch is below.
Cheers,
Lee.

Hi Andy,
I posted a brief summary on the openwrt 'General' forum earlier today ... it's
brief but will hopefully help. I've done 2 now, only bricked one (by
experimenting) and the serial cable makes it pretty easy to recover.

ever resubmitted - so here's a second go!
Basically if you make use of usb storage devices and specifically if
you want to have services make use of the storage from service start
time (for example, collectd or syslog-ng etc.) then you have a problem
... the usb device is mounted much too late in the boot sequence and
you'll find the services writing "underneath" the mount point.
Also, you may want to only start the service once the device is plugged
in (well after the boot sequence) ... can't think of a good example
here, but it's probably better to do the right thing with hotplug rather
than to hack around with the startup sequence.
So the basic idea is that in the fstab config you can specify that
specific services are started once the filesystem is mounted, this is
then handled by the hotplug system. There's also a menuconfig option to
allow you to specific services that aren't started at boot time (since
that's the default.)
This is made up of a patch to package/Makefile to handle the
non-auto-starting of services, and then a new package which I've called
block-hotplug-svcs.
An example /etc/config/fstab entry:
config mount
option target /site
option device /dev/sda1
option fstype ext4
option options rw,sync,noatime
list servicesyslog-ng
option enabled 1
option enabled_fsck 1
The code below is probably space mangled, but it's really there for
comment for now

Automatically start samba/sharing service when an external USB disk has been plugged in? And how about stopping services when an USB device has been removed. Say I have an exeternal harddisk plugged in, but I want to use it (temporarely) to transport (other) data or something. So I remove it from the router, any file sharing services should be stopped (ideally). Is it possible to support this as well? Regards, Maarten Hi Maarten, On the "stopping" front, the code actually attempts to do this, however I'm not sure how (or if) the hotplug stuff will get called *before* the device actually goes away. It would be easy to put together some kind of "eject" script that would do the right thing, but there may be a better way of achieving it. I'll happily add "eject" unless someone comes up with a better approach.

[OpenWrt-Devel] shellinabox build problems
Hi, There's a ticket open (#7043) for adding shellinabox to openwrt ... there are patches attached to it which seem to do the job, however (as you can see from the last comment in Jan) there is a problem building it. I've got what I assume is the same problem: mv -f .deps/hashmap.Tpo .deps/hashmap.Plo mv: cannot stat `.deps/hashmap.Tpo': No such file or directory If you go through Makefile.in and remove the lines containing these mv's then it seems to build ok, all except the final binary (although there's no error, just doesn't seem to be there???) So fundamentally this looks like it should build ok, and it would be really handy to have ... any ideas? I've never really understood all the deps stuff.

[OpenWrt-Devel] [PATCH] fix syslog-ng start script
Hi,
The syslog-ng start script doesn't stop syslog-ng because it tries to
use pid's instead of the executable name. Very simple patch attached.
(apologies: tabs are mangled, I'm on a webmail system and can't seem to
fix it, there are only 2 though :-))

[OpenWrt-Devel] Frequent reboot WBMR & Lantiq
Hi, I've been running the Buffalo WBMR-HP-G300H routers for a while now, actually three of them on a bonded line, and in general they are working very well. On one of the lines I am seeing very frequent reboots (of the whole system, not just the DSL) every two or three hours, the other two lines seem to be stable (although I have seen reboots on the other lines, not for the last week or so). The "faulty" line is the one that seems to sync closer to it's limit (it has a smaller noise margin) but it's been stable with other DSL routers in the past. I am going to swap the hardware around, to make sure it's not something hardware related (they are all running the same firmware), although I suspect it's a panic caused by the lantiq driver when some situation happens on the line ... the same router stayed up for over 6 weeks with no DSL connected while I was puting the build together. Is there any way to get a crash dump configured in openwrt so I can get more info about the reboot cause? Thanks, Lee. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

[OpenWrt-Devel] local domain resolver issues
Hi, I've noticed some slightly strange behaviour on trunk (certainly compared with older releases) around how names are resolved. If I have a host "fred", that I configure within LuCI then the dnsmasq command line will include records for that, with the appropriate domain (lets call it: my.domain.org) So if I'm on another machine, pointing dns at openwrt then everything is fine, my domain name is properly set and query's for "fred" without a domain get the domain added and then the result is returned. If I'm actually on the openwrt box, then whenever I run a query (ping, nslookup anything) it doesn't seem to append the domain name (I assumed it would use the "search" entry from resolve.conf, or the domain from the hostname) … neither of these seem to get looked at and the bare query is sent to dnsmasq … which doesn't know the answer since it's appended the domain onto all the host records and doesn't keep the non-appended ones. I believe the problem is with the resolver since it's clearly not using resolv.conf … has anyone else seen this? I'll continue to dig.

[OpenWrt-Devel] dnsmasq sending to all upstream servers??
You can tell I've been looking at my outgoing DNS traffic … another problem… >From looking at traffic I can see dnsmasq sending each dns request to ALL the >servers configured (two in my case) which it shouldn't be doing (I haven't got >the all-servers option enabled) So it's obviously a bit wasteful ands add upstream load, but given it seems to close the socket once it's got the first reply, it also ends up generating a icmp port unreachable for the second and presumably subsequent replies. Can anyone else confirm this? (trunk) Thanks, Lee. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
