Hello, Running 2.6.11 kernel on some host and running 2.6.5 kernel on other hosts.
I will try no to mix apples with oranges here,
I can "SSH -6" from a 2.6.11 system to a 2.6.5 system with no problems.
I can also "SSH -6" from a 2.6.5 system to another 2.6.5 system with no
problems.
When I attempt to "SSH -6" from either a 2.6.5 or a 2.6.11 system to a
2.6.11 system, I get an immediate tcp resest.
In tcp_ipv6.c, the following routine is called and the subsequent call to
"sk_for_each" fails because in list.h (in include/linux) the define
“hlist_for_each_entry” has “(head)->first” as NULL (it appears that the
link list is not set up correctly). This eventually leads to the call to
“tcp_v6_send_reset”.
static inline struct sock *__tcp_v6_lookup_established(struct in6_addr
*saddr, u16 sport,
struct in6_addr *daddr, u16 hnum, int dif)
{
struct tcp_ehash_bucket *head;
struct sock *sk;
struct hlist_node *node;
__u32 ports = TCP_COMBINED_PORTS(sport, hnum);
int hash;
/* Optimize here for direct hit, only listening connections can
* have wildcards anyways.
*/
hash = tcp_v6_hashfn(daddr, hnum, saddr, sport);
head = &tcp_ehash[hash];
read_lock(&head->lock);
sk_for_each(sk, node, &head->chain) { **********THIS
FAILS**********
/* For IPV6 do the cheaper port and family tests first. */
if(TCP_IPV6_MATCH(sk, saddr, daddr, ports, dif))
goto hit; /* You sunk my battleship! */
}
Has anyone seen an issue such as this?
Thanks,
Phil Bellino
