04.09.2016153KernelBug ReportVery LowLowKERNEL_DYNAMIC_FTRACE=y on mips => panic TrunkAssigned Task Description

Github issue #129 reported by: https://github.com/stsydow

If KERNEL_DYNAMIC_FTRACE is enabled on a MIPS system it will panic in late boot. (tested on ar71xx and malta)
The error message is not very helpful, maybe some one has an idea how to track it down:

24.08.2016115Base systemBug ReportVery LowMediumWWAN-connections using 3g with HUAWEI ME909u-521 unstab...TrunkUnconfirmed Task Description

Actually, I am trying to stabilize wwan (3g actually; LTE later on) using pppd with my HUAWEI ME909u-521,
because either my MT7620-based router locks up during boot already; or after short period of real usage.
During night, when router is almost idle, just some watchdog date sent via wwan, no problem.

First trace of a possible problem was this msg in logread:
daemon.notice netifd: wwan (1676): Error setting WWAN mode!

Wich is expected, as in /lib/netifd/proto/3g.sh:

...

                      elif echo "$cardinfo" | grep -qi huawei; then
                              case "$service" in
                                      umts_only) CODE="14,2";;
                                      gprs_only) CODE="13,1";;
                                      *) CODE="2,2";;
                              esac
                              export MODE="AT^SYSCFG=${CODE},3FFFFFFF,2,4"    #####Will not work !!!!! Switching USB-Stick to 3g-preferred ?

...
...

                      [ -n "$MODE" ] && gcom -d "$device" -s /etc/gcom/setmode.gcom

Will not work, because the ME909u-521 rejects AT^SYSCFG . However, AT^SYSCFGEX will work, but having different syntax.
MODE=”AT^SYSCFG=${CODE},3FFFFFFF,2,4” will be effective for simpler modems.

/etc/gcom/setmode.gcom returns exit 1; but this error is not checked in 3g.sh

Not shure, whether this is the reason for my problems; however, reason of concern, as high speed modems
are more and more common.
Willing to participate in testing/debugging.

For details regarding my modem, consult

16.08.201695Base systemBug ReportVery LowLowsystem looses IPv6 prefix after valid_lft reaches 0TrunkUnconfirmed Task Description

Trunk odhcp6c somehow lets the valid-lifetime of interface expire and the prefix if the quite logically getting dropped from the interface.

This has been tested on several types of interfaces ethernet copper , SFP modules , GEPON ONU SFP
and various versions of OpenWRT all resulting in the same loss of prefix.

The same tests performed on Virtual Machines running OpenWRT kernel 4.4.7 x86_64
The VM behave normally which is difficult to explain except by the difference of architecture and drivers ?

I believe that LEDE has the same problem.

I will give configuration for LEDE/OPENWRT to test with later on.

16.08.201694Base systemBug ReportVery LowMediumnetifd: PPPoE MTU problemTrunkNew Task Description

When you set the MTU of a ppp interface with proto=pppoe and ifname=nas0 via the mtu option,
the configured mtu will not be set on the ppp interface (what you want), but on the
underlying interface named by ifname (what you normally don’t want to change).

This leeds to log messages like this:


pppd[5641]: Interface nas0 has MTU of 1448 – should be at least 1500.


and MTUs other than what you really want.

example:


desired PPPoE MTU: 1448
actual nas0 MTU: 1448
actual PPPoE MTU: 1440

This issue seems to be related to the commit 7ac29b75319fd69a8a7c0aeea7804d381ec07d3d of netifd.

Regards,
Martin

07.08.201681Base systemFeature RequestVery LowLowAdd ability to limit wifi channels for "auto" channel s...TrunkUnconfirmed Task Description

A nice feature for LEDE would be ability to limit what channels are used for when setting an interface up for “auto” channel selection.

For example, on 2.4 GHz, while channels 1-11 are often available, it’s better to just use 1, 6, and 11. But for “auto” mode, the router will still sometimes pick one of the in between channels. If there was some sort of checklist where you could pick only those channels you want the algorithm to use, it would allow finer grained control over the process.

It would be trickier for the GHz band though, since there are often different power limits associated with the different bands.

13.07.201650Base systemBug ReportVery LowLowNo image or non-verbose output created if image is too ...TrunkUnconfirmed Task Description

The target/install target does not produce the *squashfs-factory.bin and *squashfs-sysupgrade.bin binaries if the images are too big to fit the selected flash size.
However, make doesn't say a word to the user but simply does not produce the files. The user has to either check the mtime of the files if they were created earlier or use

make target/install V=s

to derive what's wrong.
According to jow on IRC this is just an artifact of no way to bypass silent mode. That might be the common explanation but it is still a bug from my POV.

Currently the formatting options are not documented anywhere, and I failed to find any documentation with google. There are a few buttons to use, but they seem to be rather limited (e.g. nothing for quotations).
