Subject: [Xenomai] Does RTNET supports TCP?
Date: Fri, 5 Oct 2018 01:02:46 +0000	[thread overview]
Message-ID: <C2EC5BA46D13CD44B5915A8FEEB4C44ED1819D8C@DDCEXCH.ddc-ny.com> (raw)


Hi,

I noticed starting Xenomai 3.0.1 until now (3.0.7), there is net/ in .../kernel/drivers/ and in ../kernel/drivers/net/stack/ipv4/Kconfig

# source "drivers/xenomai/net/stack/ipv4/tcp/Kconfig"

If I uncomment out the above line, it leads to compilation error in tcp.c.

Questions:

1)      Is the commented out line intentional? (short run and long run)

2)      When will TCP be supported in RTnet?

3)      Will it ever be supported?

4)      Will this statement still holds true in tcp/Kconfig? "When the RTnet IPv4 is enabled while this feature is disabled, TCP will be forwarded to the Linux network stack."

5)      When I created a socket with rt_dev_socket(AF_INET, SOCK_STREAM, 0); and attempting to rt_dev_connect(fd, server_ip_addr, sizeof(server_ip_addr)), I get errno = 25 (Inappropriate ioctl for device).  Does it mean b/c TCP is not supported in RTnet and I attempt to connect via TCP (w/ socket SOCK_STREAM)?

Phong.
