Gregory Nutt 68a115aed9 net/icmpv6/icmpv6_autoconfig.c and icmpv6_rnotify.c: Don't take the network device down when reconfiguring only the IP address from within ICMPv6 logic. Recommended by Xiang Xiao in order to avoid the long delays of bringing some networks back up.
Normally it is required that the network be in the "down" state when re-configuring the network interface.  This is thought not to be a necessary here because.

  1. The ICMPv6 logic here runs with the network locked so there can be no outgoing packets with bad source IP addresses from any asynchronous network activity using the device being reconfigured.
  2. Incoming packets depend only upon the MAC filtering.  Network drivers do not use the IP address; they filter incoming packets using only the MAC address which is not being changed here.

mld 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
neighbor net/icmpv6, neighbor, and netdev: Rename netdev_dev_lladdrsize() to netdev_lladdrsize() and move the prototype to include/nuttx/nex/netdev.h, giving is global scope within the OS. Reviewer: This degrades the integrity of the modular architecture by introducing a new coupling via C function call. Not a good thing at all. 2018-11-09 16:05:11 -06:00

pkt net/: Fix some compile errors introduce with recent networking patches. Found in build testing. 2018-11-09 14:25:44 -06:00
procfs 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
