18.06.20192328Base systemBug ReportHighMediumAllocate resources to sort out odhcpd/dnsmasq interacti...TrunkNew Task Description

As IPv6 is being adopted, increasingly people are seeing dnsmasq log ‘spam’. See

By default under openwrt, dhcpv4 leases are handled by dnsmasq whilst dhcpv6/RA is handled by openwrt’s odhcpd.

odhcpd could handle both v4 & v6 but does not yet have the same configuration flexibility for dhcp options as dnsmasq. I guess this is why no one has been brave enough to switch to odhcpd for ipv4 operations as well as ipv6.

dnsmasq can also handle dhcpv6/RA but not quite as flexibly as odhcpd. dnsmasq will automatically find IP6 prefixes on interfaces and start handling them, whilst openwrt’s strategy with odhcpd is to only handle stuff we tell you to handle, don’t do it automagically.

As dnsmasq is the default resolver for openwrt and the wider LAN, it needs to know about DHCP/hostname allocations. For DHCPv4 this is easy, dnsmasq is controlling them. For DHCPv6 a hosts file (called a statefile in the odhcpd code) is handed to dnsmasq.

By default this host file is not read dynamically, so odhcpd has to signal dnsmasq to re-read the host file (and clear caches etc etc) upon every ipv6 lease change.

This generates a lot of log spam and process startup overhead. There are also questions about service operability during this time.

Effort needs to be put into sorting this out.

Temporary workarounds:

Use ‘hostsdir’ dnsmasq option instead of ‘addn-hosts’ - dnsmasq will dynamically scan changes/additions to hosts in hostsdir whereas addn-hosts needs a SIGHUP. Host deletions cannot be handled by this method, so odhcpd would still need to SIGHUP on lease expiry. It might reduce some of the spam.

Longer term:

Teach dnsmasq to accept hostname updates over an IPC mechanism. ubus? and carry on using odhcpd for ipv6.

Teach dnsmasq to handle ipv6 prefix additions/deletions/handling via an IPC mechanism in the same way as odhcpd. Drop odhcpd and use dnsmasq for everything.

Use odhcpd for everything and use another dns resolver that interfaces nicely with odhcpd.

Why don’t I see this problem: I use dnsmasq to handle ipv6 but I’m lucky enough that this works for me.

This needs fixing/funding to sort it out though.

19.06.20192330PackagesBug ReportVery LowHighSamba - smb.conf templating allows arbitrary injections...AllUnconfirmed Task Description

First, I have to say I’m not 100% sure it is something to be addressed within samba package itself, so forgive me if this is something you have already evaluated as not being an issue.

In short, something like that works:

    option workgroup 'WORKGROUP\
    security = share\
    guest account = root\
    interfaces = lo br-lan\

I’m not sure this works in plain openwrt images, but there exists a widely deployed commercial fork of openwrt which is definitely vulnerable to some exploit chain involving this one in the middle.
You could argue that the right of modifying uci config already gives an equivalent authorization level, or this should have been sanitized at user interface. So, is this something you consider safe?

  • Device: Ubiquiti EdgeRouter X (ramips mt7621)
  • Software: LuCI Master (f138fc93) / OpenWrt SNAPSHOT r10210-09c6885
  • Steps to reproduce: enable hardware flow offloading

Brief description:
Enabling hardware flow offloading causes kernel oops/panic, resulting in device rebooting. The device remains in a bootloop.
Hard powercycle does not resolve the kernel panic.

Steps taken to resolve the issue:
Powering the device off, disconnecting all rj45 ports then reconnecting a single rj45 cable allows to disable the hardware offload. As the hardware offload is no longer active, the issue stops from happening.

Crash logs:

Additional information:
The issue was not present prior to this snapshot. Packet capture on a device connected to eth1 port did not reveal anything strange. There was a broadcast message sent from the router to UPD port 4919 stating

 Uncompressing Kernel Image ... Unimplemented compression type 3

Checking into u-boot (make menuconfig) seems that lzma cannot be set , only LZ4 is provided.

Also the option to change compression type of the kernel do not work. I try to switch from default (gzip) to LZ4 but kernel uimage is always lzma compressed.

Could you provide some hint to unlock the situation ?

Another strange things is :

Error: ethernet@f0028000 address not set.
No ethernet found.

f0028000 is memory address of GMAC that is not provided in sama5d31 SoC but the curious is the next No ethernet found.

Does it mean that nor EMAC was found ?

Thanks in advance

14.06.20192319PackagesBug ReportVery LowHighusbmode bug which is fixed in usb-modeswitch...openwrt-18.06Unconfirmed Task Description

I wrote a bug report but then the bug report said wrong token and I lost the report... :(

Now again but shorter version. The usb-modeswitch (which seems to be an openwrt project, a rewrite of original usb_modeswitch ) needs to set some devices to config 0 before switching to config 3.

BTW this is fixed in usb-modeswitch... Here is the link to discussion about this:

Some devices need to be set to config 0 first to be able to switch to config 3. Otherwise they hang...

Here a working example:
