RFC 5095 Deprecation of Type 0 Routing Headers in IPv6 and FreeBSD

Hi, Looks like: https://svnweb.freebsd.org/base?view=revision&revision=191942 I am wondering if it should also be removed from icmp6_notify_error? ## /* * XXX: cu

Bug in ICMP redirect handling

This seems like a bug: https://svnweb.freebsd.org/base/head/sys/netinet/tcp_subr.c?r1=303457&r2=303456&pathrev=303457 I believe the ordering of if/else checks for cmd value is important as the last one checks for mapping of PRC* to an error. Given that the mapping is defined to be 0 for redirect

Re: IPv6 stacks responds to all node link local multicast NS

RFC. Also the comment in the code suggests what RFC says but the check is more liberal. Also why it is different for DAD NS vs Neighbor resolution NS. On Friday, October 17, 2014, Hiroki Sato wrote: > prabhakar lakhera > wrote > in >: > > pr> This probably is more of a co

IPv6 stacks responds to all node link local multicast NS

This probably is more of a compliance issue (or may be not as the NS receipt section of RFC 4861 http://tools.ietf.org/html/rfc4861#page-62 does not talk about it). The neighbor solicitation message format says this: http://tools.ietf.org/html/rfc4861#page-22 Destination Address

Why did KAME need ND6_LLINFO_WAITDELETE?

Hi, I see that* ND6_LLINFO_WAITDELETE *was done away with long time back. I was looking for any historical reasons for why it was needed and what triggered its removal. Any pointers will be much appreciated. Thanks! ___ freebsd-net@freebsd.org mailing

Hi, It could very well be that my brain wires are not working late in the day. >From what I know most of the routing table entries (unless referenced by some other entity or another route in routing table) have reference count 0. At least that's how things used to be in BSD as also stated in TCP I

Route addition/deletion by nd6_prefix_(on/off)link

Hi, I have a question regarding route addition and deletion from these functions for IPv6. Why do we need it? Shouldn't the address configuration take care of installing subnet routes and deletion should take care of their deletion. best, Prabhakar ___

mbuf leak in icmp6 code??

Hi, In FreeBSD icmp6 code I see function where we are either going to freeit where passed mbuf is freed or we are simply returning. For example: icmp6_input calls icmp6_redirect_input and right after it returns it makes m=NULL. Inside icmp6_redirect_input there are checks for ifp and for the mess
