[lwip-users] Stable release with IPv6 support
Omer Ilany
I'm currently using version 1.4.0 in a project I'm working on and I was wondering if IPv6 support (dual stack, as in the master branch) is going to be integrated soon into future stable releases.
Can you provide any information regarding what is the next stable version supporting IPv6 and when is it expected?
Do you have any experience with that code? Was it tested against standard linux/windows stacks?

The next release will most probably be 1.4.1 - a pure bugfix release from 1.4.0. I'd expect to finish bug fixing during November, so I expect it to be released this year.
For now, we planned to release the IPv6 code (i.e. the current master code) as 1.5.0 and I'd like to get a beta out around the same time as the 1.4.1 release.

Although the code runs pretty stable in my tests, we (in our company) haven't done any IPv6 tests. Also, I don't expect too many users currently used it as it's available via git only - that's the reason I'd like to provide a beta downloadable as ZIP.

I am using LWIP head for a project with IPv6 and UDP only. It works as expected
and so far without any problems.

I think getting the 1.4.1 release out by the end of the year should be our primary target, with 1.5.0 to follow. I haven't yet decided, or given enough thought to, what features other than IPv6 should be included in the 1.5.0 release.

Support for zero-copy DMA drivers (RX and TX) with netconn API :-)
On RX, I used
CORE_LOCKING=1
CORE_LOCKING_INPUT=1
PBUF_REF custom pbuf with custom free function

I haven't found how to make TX work without copying the frame before
sending, yet.

I may be wrong, but I think that 1.3 may be configured to support
EITHER v4 OR v6 (both at the same time is not supported).
I don't think anyone is looking at porting the dual stack back to
the 1.3 branch.

Well, there has been IPv6 support in lwIP for a while, but I don't think it really worked. I think it didn't actually compile without errors for a while now.
The IPv6 code we have now is completely new written (in addition to dual stack support).

I wouldn't advise that as there have been many other bugs fixed since 1.3.x.

I'm afraid you won't get IPv6 support from us before 1.5.0 unless you
are willing to use a version checked out from git or backport it
yourself or are lucky enough to find someone doing the work for you.
There are not many developers active for lwIP, currently, and so we
don't have a very strict and short time schedule for releases.

When will LWIP1.5.0 released ?

We don't have a time schedule, but probably not before the first quarter of the next year, I guess...

When will you release new lwIP with stable IPv6 version?
Could IPv6 work with IPv4 together ? if not, how to switch automatically ?
Thank you in advance

I think the trunk supports dual stack operation.

Hehe, I think the link you posted doesn't really fit to those mails: his mail was not replying to the original mail at all, so he should not have included the original mail at all if there's nothing of interest to his own question in it. That's not a question of top- or bottom-post, but a more general question of formatting a mail in a way that makes it easy for others to read it (and no, HTML-formatting, doubled line distance and full quoting does *not* increase the chance of such a mail being read by many people!).
And in addition to this: yes, I have already answered that question before. The answer was not too accurate and maybe that's why he now explicitly asked Kieran, not me :-)

Simon's already answered this, but I'm even more vague (I think start of
next year is optimistic). It will be released when (i) it is ready; and
(ii) we have the time to do it. I'm more concerned about getting 1.4.1
out at the moment, so won't start thinking about 1.5.0 until after that.

Thank you for your answer, what I can do now is waiting until next year, but maybe I could play contrite version first.
In fact, I have developed ftp server with lwIP, it works well enough ..and support FlashFXP and FileZilla utility.
The download speed is 200KB/s and upload speed is 40KB/s in my Cortex M3 with spi flash AT45DB321D.
I also plan to release it in LWIP contribution version ...
Hope you can allow me this ...
Appreciate very much
