33ed27ae65 Squashed commit of the following:
net/mld: Checksum calculation needs to know the full size of the IPv6 header, including the size of the extension headers.  The payload size in the IPv64 header must include the extension headers (not considered part of the header in this case).  Fixes a few additional errors in size, endian-ness and checksum calculations.  Wireshark now reports the the outgoing Report has a good checksum.

    net/mld/mld_query.c:  Add a cast to assure that the left shift does not overflow.

c6156818b0 net/mld: Fix some compile errors fill debug info is enabled. Fix some errors in formatting the Listerner report. Still has a checksum error. 2018-11-04 18:18:14 -06:00

9a75a14800 net/mld: Implement MLDv1 compatibility mode. This completes coding of MLD. MLD is, howeer, still completely untested. 2018-11-04 14:07:27 -06:00

b1a61834d9 net/mld: Review and update all MLD message receipt logic. Also ripple changs that are, hopefully, improvements back to IGMP. 2018-11-04 10:57:21 -06:00

a4dc759b4d net/mld: Defer all timeout-related operations to the work queue vs. handling within the timer interrupt. Need to notify the device driver for an immediate poll when there are MLD packets waiting to be sent. 2018-11-03 16:47:08 -06:00

6c0ab0e077 Squashed commit of the following:
include/nuttx/net/ipv6ext.h:  Fix some terminology:  Hop-by-hop, not Hop-to-hop or Hop2hop.

    net/devif/ipv6_input.c and net/icmpv6/icmpv6_input.c:  Add logic to skiip over the variable number of IPv6 extension headers that may be present between the IPv6 header and the transport layer header.  The extension headers are simply ignored.  This is necessary because with MLD, certain incoming messages may have, at a mimimum, a Router Alert Hop-by-hop extension header.

    net/inet/ipv6_setsockopt.c:  Implement the IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP socket options.

9f2cb42918 include/nuttx/net/ipv6ext.h: Create header file with all of the definitions of IPv6 extension headers that I could find. net/mld/mld_send.c: Correct the size and format of the Hop-to-hop, Router alert extension header. 2018-11-01 17:51:47 -06:00

5b7ef856a0 Squashed commit of the following:
net/mld:  The MLD logic now compiles and is much less toxic.  It still is not a proper MLD implementation:  (1) It is basically a port of IGMP, tweaked to work with IPv6 and ICMPv6 MLD messages, (2) it needs a proper analysis and comparison with RFC 3810, and (3) it is completely untested.  For this reason, it will remain EXPERIMENTAL for some time.
    net/mld:  Add some missing macros, more fixes related to IPv6 vs IPv4 types,
    net/mld:  More compilation cleaning.  Most fixups for IPv6 vs IPv4 types.
    net/mld:  Hook crudely converted .c files into build system and resolve a few of the many, many compilation/design problems.
    net/mld:  Add support for MLD statistics.
    net/mld:  Hook in MLD poll and packet transmission logic.
    net/mld:  Change references to IPv4 definitions to IPv6 definitions; Remove mld_input() since MLD piggybacks on ICMPv6 input.  Add functions to catch MLD messages dispatched by ICMPv6 input logic.
    net/mld:  As a starting point, copy all net/igmp/*.c files to net/mld/. and change all occurrences of igmp (or IGMP) to mld (or MLD).

6d93658ff8 Add new configuratin CONFIG_NET_MCASTGROUP. This option is selected automatically if either CONFIG_NET_IGMP or CONFIG_NET_MLD are selected. Most conditional logic based on CONFIG_NET_IGMP replaced with conditioning on CONFIG_NET_MCASTGROUP. 2018-10-31 15:03:51 -06:00

dde1e89b8c net/mld: Add basic build structure for Multicast Listener Discovery (MLD). No real MLD logic yet. Only a few hooks to capture and dispatch MLD ICMPv6 packets. 2018-10-31 14:10:19 -06:00
