Gregory Nutt f6b00e1966 tools/nxstyle.c: Fix logic error that prevent detecion of '/' and '/=' as operators. net/: Minor updates resulting from testing tools/nxstyle. 2019-03-11 12:48:39 -06:00
Gregory Nutt 8a3fc26b74 Squashed commit of the following:
The MLD implementation did not follow the RFC correctly when it is the Querier.  The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

    Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.

    net/mld: Group may be NULL when sending a general query

Gregory Nutt 854046a931 /net/devif/ipv6_input.c: Correct handling of IPv6 extension headers. The main confusion was that the payload length in the IPv6 header does not include its extension headers.
net/icmpv6/icmpv6_input.c:  Correct caculation of the ICMPv6 header address
    net/mld/mld_query.c:  Correct back test for group found.
    net/mld/mld_report.c: Fix host vs. network order problem.
    net/mld/mld_send.c: Correct the address used in sending the General Query.  It should be the unspecified address in that case.
    net/mld:  Querying workaround.  The MLD implementation does not follow the RFC correct when it is the Querier.  The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer since all groups are queried at once.  Instead, the design currently uses a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

Gregory Nutt 5340016104 net/mld: Very that the address of the group that we join is a valid IPv6 multicast address. 2018-11-08 06:37:46 -06:00
Gregory Nutt 9c3e65f15f net/mld: Fix a few compilation problems that cropped up in a different network configuration. Fix a logic error in setting the 'Other Querier Present' timer. Various cosmetic improvements. 2018-11-07 18:21:21 -06:00

net/mld:  Fix a couple of places where I forgot to unlock the network in the previous commit.

    net/mld:  Implement 'Other Querier Present Timer'.  This timer is used to revert to Querier mode if there is no other querier on the network.  Also, fix some naming:  The Done message is not just Version 1 but is used with Version 2 as well.

    net/igmp:  Back out some blind, backported improvements to IGMP from MLD.  There are too many subtle differences in the protocols for this to be safe.

Gregory Nutt 62e4a41209 net/mld: Add reference counting on the group joins. If there are multiple joins from the same group on this, the don't really leave the group until the matching number of leaves happen. Also add to hooks for the router case: Keep track of the number members NOT on this host. Integrate this with the Leave logic to that the group structure can persist while there no non-local members of the group as well. 2018-11-06 14:46:03 -06:00
Gregory Nutt 3db3c3952b net/mld: Standard usage of debug output macros. Add configuration options to enable MLD debug even when there network debug is disabled. Add configuration option to dump the content of outgoing MLD packets. 2018-11-05 18:39:55 -06:00
Gregory Nutt 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
Gregory Nutt 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

Gregory Nutt 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).
