<br>
I am happy that LwIP is getting into state<br>
of viable alternative of TCP/IP stack for<br>
resource constrained RTEMS targets.<br>
<br>
But as I have already reported before, I would<br>
be happy if the code licenses and locations are cleanup.<br>
<br>
The RTEMS core integration layer is held in uLan/ports/os/rtems<br>
subdirectory<br>
<br>
<a href="https://git.rtems.org/rtems-lwip/tree/uLan/ports/os/rtems/arch/sys_arch.c" rel="noreferrer" target="_blank">https://git.rtems.org/rtems-lwip/tree/uLan/ports/os/rtems/arch/sys_arch.c</a><br>
<br>
It should be moved somewhere else, i.e. under<br>
<br>
<a href="https://git.rtems.org/rtems-lwip/tree/rtemslwip/common" rel="noreferrer" target="_blank">https://git.rtems.org/rtems-lwip/tree/rtemslwip/common</a><br>
<br>
but for sure the reference to our uLAN project is nonsense in this<br>
content<br>
<br>
<a href="https://ulan.sourceforge.net/" rel="noreferrer" target="_blank">https://ulan.sourceforge.net/</a><br>
<br>
even that initial LwIP integration for RTEMS is based on our<br>
previous work in frame of that project for system-less and later<br>
RTEMS use.<br>
<br>
To make integration with RTEMS easier, the source should<br>
be relicensed to some common actual RTEMS license template,<br>
for example<br>
<br>
<a href="https://git.rtems.org/rtems/tree/bsps/arm/lpc176x/start/bspstart.c" rel="noreferrer" target="_blank">https://git.rtems.org/rtems/tree/bsps/arm/lpc176x/start/bspstart.c</a><br>
<br>
We have referenced Swedish Institute of Computer Science license<br>
there to allow integration even to some official LwIP port<br>
but except for function and defines names the code is our own<br>
so RTEMS copyright with reference to implementation inspired by<br>
other LwIP OS integration should be OK.<br>
<br>
I have contacted Premysl Houdek who worked on project during<br>
his RTEMS GSoC and followup diploma thesis<br>
<br>
<a href="https://support.dce.felk.cvut.cz/mediawiki/images/f/f1/Dp_2016_houdek_premysl.pdf" rel="noreferrer" target="_blank">https://support.dce.felk.cvut.cz/mediawiki/images/f/f1/Dp_2016_houdek_premysl.pdf</a><br>
<br>
and he is prepared to confirm relicensing to any RTEMS fitting<br>
open source license.<br>
<br>
For actual RTEMS LwIP users and contributors, please propose license change<br>
or chose some of above offers and then propose new files location including<br>
git patches or I can take that action if <br>
<br>
Best wishes,<br>
<br>
Pavel<br>
