sys/netinet6 : nd6.c nd6.h
usr.sbin/ndp : ndp.c
Log message:
Document struct nd_ifinfo protection, remove obsolete .initialized member
All access to struct ifnet's member *if_nd is read-only, with the one
write exception being nd6_slowtimo() updating ND information.
IPv6 Neighbour Discovery information is fully protected by the net lock.
---
nd6_ifattach() allocates and unconditionally initialises struct ifnet's
*if_nd member, so early in if_attachsetup() that there is no way to query
unitialised Neighour Unreachable Detection bits.
Only SIOCGIFINFO_IN6 through ndp(8) used the .initialized member:
Added/set since 2002 sys/netinet6/nd6.c r1.42
attach nd_ifinfo structure to if_afdata.
split IPv6 MTU (advertised by RA) from real link MTU.
sync with kame
Read since 2002 usr.sbin/ndp/ndp.c r1.16
use new SIOCGIFINFO_IN6. random other cleanups. sync w/kame.
Obsolete since 2017 sys/netinet6/nd6.c r1.217
usr.sbin/ndp/ndp.c r1.85
Remove knob and always do neighbor unreachable detection.
