Syrone, afaict, tc dlopen()'s iptables .so's, which implies that
iptables is needed at runtime, at least to support the associated
features.

I didn't get circular dependency problems with this either.

[LEDE-DEV] [PATCH] libubox: Fix -Wsign-compare warnings

[Rosen Penev]

-Wsign-compare is part of the -Wextra series of warnings so it's worth fixing. 
The issues are mainly sign conversion ones.

[LEDE-DEV] [PATCH RFC] ar8216: (try to) implement get_port_stats

[Vittorio Gambaletta (VittGam)]

Hello,

TP-LINK, in their new TL-WR1043ND v4, for some reason wired the
ethernet LEDs not to the AR8337, but to the QCA956x SoC instead.

This means that the switch LED trigger needs to be used for all
of the ethernet LEDs (4 x LAN and 1 x WAN), like on the AR9341
when its internal switch is used.

But the ar8216/8327/8337 switch driver does not implement the
get_port_stats function, so the LEDs are lit but do not blink
when traffic passes through the ports.

(By the way, if I remember well, the stock firmware of this router
does not make those LEDs blink either...)

I've tried to write the needed function, as you can see in the
patch below.

The problem is that now a kworker kernel thread is constantly
consuming 12-15% of CPU. It stops when I change the trigger on
the LEDs to something else via sysfs. So, there is clearly
something wrong with it. But what?

The implementation for the AR9341 internal switch (in
target/linux/ar71xx/files/drivers/net/ethernet/atheros/ag71xx/ag71xx_ar7240.c)
does it in a quite similar way (it actually polls ALL the switch
ports every time data for a single port is requested...), but
it uses 0% CPU instead.

What do you think?

Thank you!

Best regards,
Vittorio G

[LEDE-DEV] [PATCH] rules.mk: disable CXX11 ABI with uClibc++

[Stijn Tintel]

GCC 5.1 introduced a new library ABI to conform to the 2011 C++
standard. This new ABI is enabled by default. This causes compatibility
issues between libraries compiled against libstdc++ and libraries
compiled against uClibc++, as the latter doesn't support this new ABI.

Solve this by disabling the _GLIBCXX_USE_CXX11_ABI macro when uClibc++
is selected as the preferred standard C++ library.

Sorry for the delay, but I just also compile-tested this ;)

With gcc 4.7.2, the following further changes are needed to compile the code.
Can you take them and send a v2?

It will be really nice if the size can be squeezed for at least the
ip-tiny package.  Are you already working on this?

The other thing is that adding iptables as a build dependency should
be the way to go if only header files of that packages are needed to
build iproute2.

[LEDE-DEV] Kodi feed

[Stijn Tintel]

Hi all,

After a minor cleanup, I published [0] Kodi and dependencies for running
on the brcm2708 target (Raspberry Pi). Dependencies for this are in the
kodi branches of my LEDE staging tree [1], and my fork of the packages
feed [2].

I am currently working on x86 support, but it's taking longer than
expected so I decided to already post what's working. If you want to
contribute, please contact me first (preferably on IRC), to avoid
duplicate effort.

Several packages have a hard dependency on libstdcpp. This is either due
to uClibc++ not supporting shared_ptr (kodi, libcec), or to avoid
linking problems (taglib, tinyxml).
The Kodi patch 900-musl-compat.patch is ugly, especially the "iofile.h"
part. Unfortunately the Kodi patch from Alpine that addresses this issue
[3] doesn't apply to Kodi 17, so I went for a quick & dirty fix.
Suggestions for a clean fix that can be submitted upstream are very welcome.

Thanks,
Stijn
