Hi, We have been working on a TRILL implementation in the Linux kernel for some time now. We have sent a first RFC a year ago (already!) and we are back with a second version; this time we will try to update more quicly according to the comments. The code has been pushed here https://github.com/Gandi/ktrill.git in the devel branch (be careful this branch is constantly rebased!) Attached a series of patch as a second request for comment. The code is not perfect and probably still lacks of improvements. It's a second request of comment in order to get some feedbacks. This code has been tested for some time now.
These patch tries to implement TRILL protocol RFC 6325. As a first implementation, some RFC details are still not implemented. In order to test these patches please follow the instruction: download quagga (userland) from here https://github.com/Gandi/quagga.git compile it using these options ./bootstrap.sh && ./configure --localstatedir=/var/run/quagga \ --enable-isisd --enable-trilld --enable-trilld-monitoring --disable-ipv6 \ --disable-ospfd --disable-ospfclient --disable-ripd --disable-babeld \ --disable-bgpd && make && make install start zebra and trilld $ zebra -f $ZEBRA_CONF -P 2121 -u quagga -d $ trilld -f $TRILLD_CONF -P 2021 -u quagga -d Configuration sample can be found here https://github.com/Gandi/quagga/blob/dev_trill/zebra/zebra.conf.sample and here https://github.com/Gandi/quagga/blob/dev_trill/isisd/trilld.conf.sample Finally you need to correctly configure bridge port For access port (native frames) echo 4 > /sys/class/net/<INTERFACE>/brport/trill_state For trunk port (trill frame and control frames) echo 8 > /sys/class/net/<INTERFACE>/brport/trill_state more detail can be found here: https://github.com/Gandi/ktrill/wiki NB: for port state github version has different flags as we did not take into consideration all port flag when implementing it --- Changes in V2: - rebase on v4.2 tag - replace genl netlink by rtnetlink - each port will either have TRILL or bridge packet handler deponding on bridge status in version 0 all port used to have a unique handler that fallback to bridge handler if trill is not enabled - remove usesless locks - remove all format errors - handle TRILL packets within packet split process Ahmed Amamou (19): net: rbridge: add trill frame description net: rbridge: add RBridge structure net: rbridge: add CONFIG_TRILL net: rbridge: adapt Bridge structure net: rbridge: enable/disable TRILL capability net: rbridge: add sysfs for trill_state net: rbridge: get Rbridge nickname from daemon net: rbridge: add elected dtroot net: rbridge: add rbr_node management function net: rbridge: clean up rbr_node on rbridge stop net: rbridge: update node table net: rbridge: add basic trill frame handling function net: rbridge: update forwarding database net: rbridge: add test on trill flag before flood net: rbridge: add encapsulation process net: rbridge: add receive function net: rbridge: add rbr_fwd net: rbridge: add rbr_multidest_fwd net: rbridge: replace net_port rx_handler François Cachereul (1): net: rbridge: add layer 2 IS-IS Ethertype William Dauchy (1): net: handle packet split for trill include/linux/etherdevice.h | 17 + include/net/if_trill.h | 88 ++++++ include/uapi/linux/if_ether.h | 2 + include/uapi/linux/if_link.h | 6 + net/bridge/Kconfig | 8 + net/bridge/Makefile | 2 + net/bridge/br_fdb.c | 41 +++ net/bridge/br_forward.c | 37 ++- net/bridge/br_if.c | 7 +- net/bridge/br_netlink.c | 10 +- net/bridge/br_private.h | 53 ++++ net/bridge/br_sysfs_br.c | 38 +++ net/bridge/br_sysfs_if.c | 26 ++ net/bridge/rbr.c | 718 ++++++++++++++++++++++++++++++++++++++++++ net/bridge/rbr_private.h | 85 +++++ net/bridge/rbr_rtnetlink.c | 93 ++++++ net/core/flow_dissector.c | 31 ++ 17 files changed, 1259 insertions(+), 3 deletions(-) create mode 100644 include/net/if_trill.h create mode 100644 net/bridge/rbr.c create mode 100644 net/bridge/rbr_private.h create mode 100644 net/bridge/rbr_rtnetlink.c -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
