This allows better performance and management of DNS functionality on your local network. You should review the, r34106 (stamp files for build variants) broke dnsmasq package's dhcpv6 variant. The strange thing is that I can flash again those firmware images that I know from earlier experience to be working. As my kernel is 13.994 x 64k, no buffer gets actually added as (13.994 gets rounded down to 13, then 1 is added, and 14.00 is the final about of 64k blocks used.). Of course, if you change all instances of home.example.com to a real domain and set up some glue records you can get to all the devices from the outside (provided you have port forwards set, of course). option interface 'lan' It looks like including dnsmasq-dhcpv6 variant after r34106 causes the router not to boot up. If you first build a pre-34106 version and do then svn up to post-r34106 and build without a "make clean", the build is normal and boots. 1537853508 18:b4:30:be:9a:b0 192.168.3.120 01:18:b4:30:be:9a:b0, Mon Sep 24 09:06:59 2018 daemon.notice odhcpd[1529]: Got DHCPv6 request THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. But I'm sure I see DHCPv6 leases being issued in the log. The steps to get this working are as follows: The first step is to install the required packages. $(STAGING_DIR_HOST)/bin/lzma e $(1) -lc1 -lp2 -pb2 -d20 $(2). option dnssec '1' (see below from lzma help file.). ### SQUASHFS LOAD ERROR<0> for image!

Thank you for leading me to discover the solution! Configure dnsmasq to provide DHCP and DNS Bonus: Dynamic IPv6 firewall rules Install Packages The first step is to install the required packages. Sections Sign in ), overall it's not a terribly painful process. Dnsmasq serves as a downstream caching DNS server advertising itself to DHCP clients. 1537868050 c0:c1:c0:4b:ca:b9 192.168.1.103 * Changeset r34106 (isolating stamp files for build variants) has apparently broken dnsmasq package's dhcpv6 variant. There are times when you need to filter out what some hosts in the network can or cannot do. I had to de-brick it with a TFTP flash to get it back to running order. option limit '150' First we'll add a firewall rule to be dynamically updated: Upon a new or renewed lease, Dnsmasq calls the script /usr/lib/dnsmasq/dhcp-script.sh, which, in turn calls /sbin/hotplug-call dhcp (after setting up an environment). Restart your dnsmasq server to activate the new settings and verify that your clients successfully receieve IPv6 addresses. Dnsmasq, however does provide such callbacks making automatic updating of firewall rules a relative breeze. it has also been fairly reliable for me for several months. Details are below. I have solved this by deleting the lease files (/var/lib/NetworkManager/.lease on Ubuntu and /var/lib/dhcpcd5/.lease on Raspbian) and then reconnecting the network. Full bootlog again includding the few first lines, and my correct name Additional info: So, we need to add some sections to the /etc/dnsmasq.conf file that contains the remainder of the configuration. ### SQUASHFS loading 'image/uImage' to 0x80800000 1537839435 d0:13:fd:64:d9:db 192.168.1.114 * 01:d0:13:fd:64:d9:db Jow is probably right that it is not about that package. option domain 'lan' I have uploaded the build r34174-2012-11-12-2328 to http://koti.welho.com/hnyman1/Openwrt/trunk_error_does_not_boot/ , so if somebody wants to test the build with a v1, please do so.

I am thinking about alternative explanations, and the first that comes into mind is the current ar71xx/wndr3700 kernel size optimization in the build process. Apparently the previous build's leftovers are enough to get included in the final firmware. option interface 'guest' But the router does not start after the flash. option leasefile '/tmp/dhcp.leases' I have managed to set up DNS on my router without the need for static IP addresses using dnsmasq as the main DHCP client. Also, in case it matters, unbound is working as a fully I then modified the ar71xx image makefile and removed those non-standard compression parameters from the lzma command line. root@OpenWrt:~# cat /etc/config/dhcp config dnsmasq option domainneeded '1' option boguspriv '1' option filterwin2k '0' option localise_queries '1' option rebind_protection '1' option rebind_localhost '1' option local '/lan/' option domain 'lan' option expandhosts '1' option nonegcache '0' option authoritative '1' option readethers '1' option leasefile '/tmp/dhcp.leases' option resolvfile . Restart your dnsmasq server to activate the new settings and verify that your clients successfully receieve IPv6 addresses. I see DHCPv6 leases displayed until I remove "dnsmasq" and install "dnsmasq-full". At the first glance it looks like the lib_bootstarp/lzmadecode.c basicly So that some bit does not get toggled by flashing any more, and it randomly depends on the firmware image, if the bit is right. dhcp: Yup, removing odhcpd-ipv6only has corrected the issue. errors are returned, but in most cases just LZMA_RESULT_DATA_ERROR is Alternatively, the new Virtualbox version 4.2.4 screws things up. dnsmasq's dhcpv6 variant got introduced by r32764. It would be helpful if you could attach serial and capture the bootlog of the device failing to boot. I built 34036 and 34066 fully from scratch and they both worked both in v1 and v2. 1537832014 b4:f7:a1:be:e3:00 192.168.3.115 * 01:b4:f7:a1:be:e3:00 The problem with odhcpd is that it doesn't provide script callbacks that will notify of new or renewed DHCP leases. Can you please attach the output of scripts/diffconfig.sh of a config that triggers this problem? I really fail to see how a broken dnsmasq-dhcpv6 would prevent the router from booting. Hang on, odhcpd? And that has worked ok. After r34106 that combination stops the router from booting. list dhcp_option '252,"\n"', config dhcp 'wan' option ignore '1', config dhcp 'guest' While there is a little bit of configuration involved and a couple of custom scripts to fill in the functionality gaps (be sure to include the files in your backups! After r29406 an "estimation version" of the kernel is built first, its size is assessed and then the final kernel is built with the size set by the estimation. https://forum.openwrt.org/viewtopic.php?id=40565. The DHCP subsystem supports DHCPv4, DHCPv6, BOOTP and PXE. This issue is probably due to my router handling DNS/DHCP different than the standard openWrt setup. option ra 'server' option localise_queries '1' 1537850651 00:18:39:43:3b:49 192.168.1.104 01:00:18:39:43:3b:49 (I made the last build without clean, as it was supposed change just the image creation), Read about the lzma/xz memory consumption here: Mon Sep 24 09:06:59 2018 daemon.warn odhcpd[1529]: DHCPV6 RENEW IA_NA from 00010001232af947bcaec50ff2b3 on br-lan: ok 2601:601:9280:2081::102/128. I have now a serial to USB converter and the bootlog from serial console is as below. This ticket should maybe closed as invalid and a new one opened, as the problem description is wrong. When I receive the serial port converter, I will test my 3700v1 and see the boot log what it says. http://linux.die.net/man/1/lzma This website uses cookies. option dhcpv6 'server' But if you "make clean" and build then a post-r34106 version, the build succeeds but is not bootable. Hopefully that will give some insights. OpenWrt uses dnsmasq and odhcpd to serve DNS / DHCP and DHCPv6 by default. option nonwildcard '1' It includes proxy-mode, where the PXE system co-operates with another DHCP server. I just didn't have to do this with LEDE V17. As you're probably aware, IPv6 prefixes can change pretty frequently depending on your ISP. Why should that surface then now, is then more problematic to answer That was made 4 years ago, so it is really old, but is a deviation from the Netgear's own routines, shown in forum: https://forum.openwrt.org/viewtopic.php?pid=183591#p183591. The key part is probably: I earlier thought that it might be faulty flash memory, but at the first glance that does not sound like that, as checksum is right, but lzma_fs returns error regarding squashfs. I stopped the u-boot boot process with keyboard and tried a few commands in u-boot.

The dnsmasq DHCPv6 server provides the same set of features as the DHCPv4 server, and in addition, it includes router advertisements and a neat feature which allows nameing for clients which use DHCPv4 and stateless autoconfiguration only for IPv6 configuration.

So no clue from the error number. Firewall settings It's important to note that the addresses your clients will be reachable publically, much unlike the standard IPv4+NAT setup commonly used. 1537850779 04:5d:4b:49:16:32 192.168.1.171 * 01:04:5d:4b:49:16:32 I will attempt to increase the buffer set in Makefile and try rebuilding tonight. option expandhosts '1' 1537857704 00:26:2d:00:84:5b 192.168.1.100 01:00:26:2d:00:84:5b opkg_install_cmd: Cannot install package dnsmasq-dhcpv6. Start with editing /etc/config/dhcp to add the following tag definitions in the file (tag identifier can be any string, I chose these for clarity purposes): These definitions stop the DHCP server from providing gateway and/or DNS information to the hosts they are applied to. Looks like the reason was indeed the lzma compression parameters. In particular, on my router both DNS and DHCP are handled by unbound. http://nbd.name/gitweb.cgi?p=openwrt.git;a=commitdiff;h=6fb33f05da8ff895875cb8d98a7c18e9c606e205. My kernel size is currently quite at a 64 kB border (917117, 916862 B = 13,994 x 64kB), and I am thinking if it is possible that the estimation is a few bytes short and the final kernel image just crosses the border by a few bytes and thus the kernel bootline gets set wrong. Firewall settings It's important to note that the addresses your clients will be reachable publically, much unlike the standard IPv4+NAT setup commonly used. lucenera January 14, 2019, 8:18pm #5 I followed the Github page of the Stubby package to configure DNS on TLS. If the prefix were to change, your existing firewall port forwards for IPv6 will be crippled until you manually re-set them at some point. 1537869657 78:d2:94:4f:ec:21 192.168.1.126 * * DNS and DHCP configuration for OpenWRT https://wiki.openwrt.org/doc/uci/dhcp The dnsmasq and dhcpd configuration is located in /etc/config/dhcp and controls both DNS and DHCP server options. (according to juhosg, this will probably be later fixed in AA, after the rc1 images have been built.). By Edgewall Software. I checked some of the the "bad builds" with a hex editor, but there are a few dozens of 00 bytes at the end of the kernel area, so kernel size overflow is not the reason. Both versions worked in both of my routers. My whole purpose of setting up Dnsmasq rather than odhcpd to begin with was because I was trying to create dynamic IPv6 firewall rules. SQUASHFS error: squashfs_readdir: read_block I see DHCPv6 leases displayed until I remove dnsmasq and install dnsmasq-full. I have flashed both routers over 100 times, but that should not be too much for the flash chip, should it? You really need to know why you want to prefer dnsmasq over odhcpd for IPv6, there's a reason why odhcpd is developed - dnsmasq is lacking in regards to dynamic prefixes (thanks dear ISPs) and other domains. returns 0 for success and 1 for most errors. There are my options to dnsmasq that aren't available through the standard configuration files. 1537853321 18:b4:30:a8:a6:df 192.168.3.245 * * http://koti.welho.com/hnyman1/Openwrt/trunk_error_does_not_boot/Netgear3800_uboot.zip. option ra_management '1', dhcp.leases: dnsmasq can also be configured to cache DNS queries for improved DNS lookup speeds to previously visited sites. If nobody suggests anything better, I will continue to live with this change: Fixed in trunk with r34248 which applies the 20-bit dictionary size option "-d20" to just wndr3700/3800 instead of all ar71xx images.

This how-to provides most common dnsmasq and odhcpd tuning scenarios adapted for OpenWrt. dnsmasq. let 'kk = (((s + c) / (64 * 1024) + 1) * 64)'; which sets the allocated kernel size. It sets the size based on the estimation size, it first calculates the used 64k blocks and rounds upward to the next 64 kB size. Let's add one: This script simply does a sanity check to ensure we're updating the firewall rule to the correct host by matching the hostname and the DUID. Somehow it sounds like there is an illegal structure in the squashfs compressed image that breaks the decompression, or something like that. 1537864168 b8:27:eb:e6:08:9b 192.168.1.106 * I was unable to connect to the router with telnet or SSH, so there is no bootlog available.

"Active DHCPv6 Leases" on status page is empty if system is running dnsmasq-full. The text was updated successfully, but these errors were encountered: Please provide your /etc/config/dhcp and a scrubbed example of /tmp/dhcp.leases from your setup. There are multiple ways to delegate and obtain IPv6-prefixes, the most common way is that your ISP delegate a prefix to you using slaac or dhcpv6. Changeset r34106 (isolating stamp files for build variants) has apparently broken dnsmasq package's dhcpv6 variant. Windows doesn't seem to be affected. Now I'm thinking when I remove dnsmasq I also need to remove odhcpd-ipv6only before installing dnsmasq-full. One supporting factor for this line of reasoning is that there was one firmware version, the first with which I noticed this problem, where I had succesfully flashed my 3700v1, but that then failed in a 3700v2, although it had been built on the same compilation run. One idea is the lzma parameters " -lc1 -lp2 -pb2 ", which have been introduced without any explanation four years ago with r12628. If nobody else starts complaining about similar issues, this might be something specific to my buildhost :-( My build host is Ubuntu 12.04 x64 in Virtualbox, but I have used the same machine to build Openwrt since April 4-5 times per week, so it sounds strange that it would have broken down now. If you do not agree leave the website. option dhcpv6 'server' Every received DNS query not currently in cache is forwarded to the upstream DNS servers. And that booting difference sounds strange. I actually created the images with two different parameter lines in target/linux/ar71xx/image/Makefile: First that already discussed removal of the current parameters: But then also with original parameters, but added the directory size limitation from the default 8MB to 1 MB = 20 bits.

WNDR3700-trunk-r34105-2012-11-11-1841.diffconfig. I have also tried having both enabled, but that does not work either. For this setup, the version of dnsmasq built-in to OpenWRT does not have DNS functionality. Have a question about this project? But the router does not start after the flash. Is there any good way to check the flash quality? 1537839170 e0:4f:43:d9:e6:d7 192.168.3.186 * Request an /56-prefix using dhcpv6-pd and configure a prefix delegation; Set up dnsmasq to handle router advertisement and dhcpv6 along side the regular dhcp for IPv4; And then covering some basics. dnsmasq provides a DNS server, a DHCP server with support for DHCPv6 and PXE, and a TFTP server. Based on the line number 547, the error is probably coming quite from the end Dictionary size will stay at the default 23 bits for the other routers. privacy statement. Already on GitHub? When the router "did not boot", it started the boot process but then got stuck in the middle, just the power led slowly blinking. The firmware gets built normally and there is no apparent fault in the build process. Otherwise the system is working fine, I can see in DHCPv6 leases being issued. My last build 34174 runs ok in 3700v2, but does not boot in 3700v1. I will rebuild 34085 once again from scratch and retry. Reading whole flash contents from /dev/mtd and comparing to the original image? When you have a router running OpenWRT this can be done at the firewall level. option resolvfile '/tmp/resolv.conf.auto' The versions are built during the same build run, so they should be as identical as possible. If you want to contribute to the OpenWrt wiki, please post HERE in the forum or ask on IRC for access. option local '/lan/' option interface 'wan' Instead, we'll want to install dnsmasq-full opkg update && opkg install dnsmasq-full I guess that router somehow does not boot properly from u-boot to kernel, or something like that. option authoritative '1' Could a bad flash chip be a reason? option dnsseccheckunsigned '1', config dhcp 'lan' But if youre not much into advanced configuration and just want to completely block out some network hosts from reaching the internet (and hence phoning home) then its a lot simpler to do this directly from the DHCP and simply leave them without a DNS and gateway configuration. option rebind_localhost '1' It looks like including dnsmasq-dhcpv6 variant after r34106 causes the router not to boot up. http://sourceforge.net/projects/lzmautils/forums/forum/708858/topic/3965542, Based on those articles, it might be sensible to either revert to default parameters, or based on seeing the parameters at staging_dir/host/bin/lzma to change the default directory size from 23 bits (8 MB) to something smaller, as the firmware is usually much smaller.
