This series adds basic IPv6 support to U-boot. It is a reboot of my earlier work on this[1].
Most of this is ported from Allied Telesis' additions to u-boot[2]. (Note that I am employed by Allied Telesis[3]). The hard work was done some time ago by Angga, I've cleaned it up and made some improvements with the hope of getting it accepted upstream. This is still very much a work in progress but it is functional. If anyone is willing/able to test on some other hardware I'd appreciate some feedback. If it's helpful for testing I'm keeping the 'ipv6' branch of https://github.com/cpackham/u-boot.git up to date with these changes. A few open issues 1) rxhand_f currently takes an struct in_addr. TFTP doesn't use this (I haven't looked at other users). To support V6 this may need to be a new union, a void * with some kind of flag or nothing if no rxhandler actually cares. It has been suggested that this parameter be removed and any users that care can re-parse the packet. 2) Unit tests. This code needs them. The testing so-far has been ad-hoc manual testing using qemu-x86. 3) Fancy v6 feature xyz. There are a lot of things that _could_ be implemented on top of this (DHCPV6 and SLAAC are two obvious things that stick out). For now I want to concentrate on getting the core code stable and accepted, if anyone else wants to work on either of those features that'd be great. -- [1] - http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/151390 [2] - http://www.alliedtelesis.co.nz/support/gpl/other.html [3] - some of this has been done on work time, other parts have been done in my personal time. Since I'm subscribed to the list using my gmail account I've signed using that. Changes in v2: - Split environment variables from main implementation - remove "prefixlength6" environment variable. The prefix length is now set when specifying the address i.e. setenv ip6addr 2001:db8::1/64. - split ping6 support into separate patch - split environment variables into separate patch - change ip6_ndisc_* to ndisc_*, fix CamelCase - split ping6 support into it's own patch Chris Packham (11): Initial net6.h lib: vsprintf: add IPv6 compressed format %pI6c lib: net_utils: make string_to_ip stricter lib: net_utils: add string_to_ip6 net: add definition of udp_hdr net: IPv6 skeleton and environment variables net: IPv6 support net: Add ping6 command and implementation net: TFTP over IPv6 net: IPv6 documentation net: e1000 enable multicast reception README | 3 + common/Kconfig | 15 ++ common/cmd_net.c | 41 +++++ doc/README.ipv6 | 32 ++++ drivers/net/e1000.c | 5 + include/env_callback.h | 8 + include/env_flags.h | 9 + include/net.h | 18 +- include/net6.h | 262 ++++++++++++++++++++++++++++ lib/net_utils.c | 132 +++++++++++++- lib/vsprintf.c | 154 ++++++++++++++--- net/Kconfig | 5 + net/Makefile | 3 + net/ndisc.c | 266 ++++++++++++++++++++++++++++ net/ndisc.h | 25 +++ net/net.c | 41 ++++- net/net6.c | 459 +++++++++++++++++++++++++++++++++++++++++++++++++ net/ping6.c | 111 ++++++++++++ net/tftp.c | 58 +++++++ 19 files changed, 1616 insertions(+), 31 deletions(-) create mode 100644 doc/README.ipv6 create mode 100644 include/net6.h create mode 100644 net/ndisc.c create mode 100644 net/ndisc.h create mode 100644 net/net6.c create mode 100644 net/ping6.c -- 2.5.3 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
