2006-02-04[ICMP]: Fix extra dst release when ip_options_echo failsHerbert Xu
When two ip_route_output_key lookups in icmp_send were combined I forgot to change the error path for ip_options_echo to not drop the dst reference since it now sits before the dst lookup. To fix it we simply jump past the ip_rt_put call. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

We should never touch the dst lock in softirq context. Since inet6_destroy_sock may be called from that context due to the asynchronous nature of sockets, we can't take the lock there. In fact this sk_dst_reset is totally redundant since all IPv6 sockets use inet_sock_destruct as their socket destructor which always cleans up the dst anyway. So the solution is to simply remove the call. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-02-02[SCTP]: Fix 'fast retransmit' to send a TSN only once.Vlad Yasevich
SCTP used to "fast retransmit" a TSN every time we hit the number of missing reports for the TSN. However the Implementers Guide specifies that we should only "fast retransmit" a given TSN once. Subsequent retransmits should be timeouts only. Also change the number of missing reports to 3 as per the latest IG(similar to TCP).

2006-02-02[IPV6]: Don't hold extra ref count in ipv6_ifa_notifyHerbert Xu
Currently the logic in ipv6_ifa_notify is to hold an extra reference count for addrconf dst's that get added to the routing table. Thus, when addrconf dst entries are taken out of the routing table, we need to drop that dst. However, addrconf dst entries may be removed from the routing table by means other than __ipv6_ifa_notify. So we're faced with the choice of either fixing up all places where addrconf dst entries are removed, or dropping the extra reference count altogether. I chose the latter because the ifp itself always holds a dst reference count of 1 while it's alive. This is dropped just before we kfree the ifp object. Therefore we know that in __ipv6_ifa_notify we will always hold that count. This bug was found by Eric W. Biederman. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2006-02-01SUNRPC: Move upcall out of auth->au_ops->crcreate()Trond Myklebust
This fixes a bug whereby if two processes try to look up the same auth_gss credential, they may end up creating two creds, and triggering two upcalls because the upcall is performed before the credential is added to the credcache. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2006-02-01SUNRPC: Fix a lock recursion in the auth_gss downcallTrond Myklebust
When we look up a new cred in the auth_gss downcall so that we can stuff the credcache, we do not want that lookup to queue up an upcall in order to initialise it. To do an upcall here not only redundant, but since we are already holding the inode->i_mutex, it will trigger a lock recursion. This patch allows rpcauth cache searches to indicate that they can cope with uninitialised credentials. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2006-01-31[IPV6] tcp_v6_send_synack: release the destinationEric W. Biederman
This patch fix dst reference counting in tcp_v6_send_synack Analysis: Currently tcp_v6_send_synack is never called with a dst entry so dst always comes in as NULL. ip6_dst_lookup calls ip6_route_output which calls dst_hold before it returns the dst entry. Neither xfrm_lookup nor tcp_make_synack consume the dst entry so we still have a dst_entry with a bumped refrence count at the end of this function. Therefore we need to call dst_release just before we return just like tcp_v4_send_synack does. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

2006-01-31[BRIDGE]: Fix device delete race.Stephen Hemminger
This is a simpler fix for the two races in bridge device removal. The Xen race of delif and notify is managed now by a new deleted flag. No need for barriers or other locking because of rtnl mutex. The del_timer_sync()'s are unnecessary, because br_stp_disable_port delete's the timers, and they will finish running before RCU callback.

2006-01-31[IPV4]: Always set fl.proto in ip_route_newportsPatrick McHardy
ip_route_newports uses the struct flowi from the struct rtable returned by ip_route_connect for the new route lookup and just replaces the port numbers if they have changed. If an IPsec policy exists which doesn't match port 0 the struct flowi won't have the proto field set and no xfrm lookup is done for the changed ports.

2006-01-27[PATCH] ieee80211: Add helpers for IBSS DFS handlingZhu Yi
To support IEEE 802.11h in IBSS, an ibss_dfs field is added to struct ieee80211_network. In IBSS, if one STA sends a beacon with DFS info (for radar detection), all the other STAs should receive and store this DFS. All STAs should send the DFS as one of the information element in the beacon they are scheduled to send (if possible) in the future. Since the ibss_dfs has variable length, it must be allocated dynamically. ieee80211_network_reset() is added to clear the ibss_dfs field. ieee80211_network_free() is also updated to free the ibss_dfs field if it is not NULL.

The following patch fixes these problems in MLDv2: 1) Add/remove "delete" records for sending change reports when addition of a filter results in that filter transitioning to/from inactive. [same as recent IPv4 IGMPv3 fix] 2) Remove 2 redundant "group_type" checks (can't be IPV6_ADDR_ANY within that loop, so checks are always true) 3) change an is_in() "return 0" to "return type == MLD2_MODE_IS_INCLUDE". It should always be "0" to get here, but it improves code locality to not assume it, and if some race allowed otherwise, doing the check would return the correct result.
