This patch series makes RTnet's tcp module usable again. It was not
working due to several bugs which showed up in combination with reworked
RTDM of Xenomai 3.
Tests on real hardware (little endian) were successful. A test on big
endian is still pending.
Sebastian Smolorz (8):
net/tcp: return u
Closing a connected TCP socket initiates a handshake procedure. The
closing socket is supposed to receive two more packets and send one
ACK at the end. RTnet's TCP stack tries to get a reference to a
socket before writing data to its buffer. Taking a reference to an
RTnet socket in Xenomai 3 is rea

Setting TCP header flags like ACK was fragile and not working when
RTnet was running on big endian processors. Use the macro provided
by the linux kernel for setting the TCP flags instead.

In the following situation a recv() call to a RT-TCP socket returned 0
although there was data already copied to the caller's buffer:
- S1 connects to S2
- S1 calls recv() with buffer size b1
- S2 sends data of size b2 < b1
- S1 receives the data, copies it to its buffer and waits for more data
-
listen() and shutdown() pass their simple int argument directly casted to
void *arg, not as a pointer to their value.

A bug in rt_tcp_recvmsg() prevented an application to receive data
over an RTTCP socket. Data was not copied back to the application's
buffer but rather into a temporary kernel buffer.

Hard to find a UP target these days, and we definitely want to be
generic with Debian packages.

Hi Sebastian,
Your patch (fixing TCP flags endianness issue) does work. (I was under the
impression to use tcp_flag_word and fix it in rt_tcp_set_flags() which I
reported doesn't work earlier.)

Hi all,
as I was (and still am) in the need to test also non-x86 from time to time, I
hacked up a little framework for generating bootable Debian images with Xenomai
pre-installed. It's currently hosted on my personal github space:

This looks really good. How easy is it to add more targets? I looked
at the jailhouse-images commits to see how to add a board, is that a
good place to start to see how to add a new board?

Dear all,
I am trying to run 32bit applications on 64bit xenomai. I installed xenomai
2.6.0 on fedora 13 x86_64. I installed all 32bit GCC lib & c librarys
(glibc-devel.i686 & going.i686).
I made one hello world sample (non-rt) app, it is giving error while running

Yes, it is. But I'll likely commit at least one real exam

Thank you Jan.
For my project requirement I am working with xenomai 2.6.0 on fedora 13.
My doubt is at least sample app compiled as a 32bit exe on 64bit kernel
should work. But it is not running on xenomai patched 64bit os,why?
