2010-12-02tipc: Eliminate obsolete native API forwarding routinesAllan Stephens
Moves the content of each native API message forwarding routine into the sole routine that calls it, since the forwarding routines no longer be called in isolation. Also removes code in each routine that altered the outgoing message's importance level since this is now no longer possible. The previous function mapping (parent function, and child API) was as follows: tipc_send2name \--tipc_forward2name tipc_send2port \--tipc_forward2port tipc_send_buf2port \--tipc_forward_buf2port After this commit, the children don't exist and their functionality is completely in the respective parent.

2010-12-02tipc: Remove obsolete native API files and exportsAllan Stephens
As part of the removal of TIPC's native API support it is no longer necessary for TIPC to export symbols for routines that can be called by kernel-based applications, nor for it to have header files that kernel-based applications can include to access the declarations for those routines. This commit eliminates the exporting of symbols by TIPC and migrates the contents of each obsolete native API include file into its corresponding non-native API equivalent. The code which was migrated in this commit was migrated intact, in that there are no technical changes combined with the relocation.

2010-12-02tcp: Add timewait recycling bits to ipv6 connect code.David S. Miller
This will also improve handling of ipv6 tcp socket request backlog when syncookies are not enabled. When backlog becomes very deep, last quarter of backlog is limited to validated destinations. Previously only ipv4 implemented this logic, but now ipv6 does too. Now we are only one step away from enabling timewait recycling for ipv6, and that step is simply filling in the implementation of tcp_v6_get_peer() and tcp_v6_tw_get_peer(). Signed-off-by: David S.

2010-12-01Bluetooth: Automate remote name requestsJohan Hedberg
In Bluetooth there are no automatic updates of remote device names when they get changed on the remote side. Instead, it is a good idea to do a manual name request when a new connection gets created (for whatever reason) since at this point it is very cheap (no costly baseband connection creation needed just for the sake of the name request). So far userspace has been responsible for this extra name request but tighter control is needed in order not to flood Bluetooth controllers with two many commands during connection creation. It has been shown that some controllers simply fail to function correctly if they get too many (almost) simultaneous commands during connection creation. The simplest way to acheive better control of these commands is to move their sending completely to the kernel side. This patch inserts name requests into the sequence of events that the kernel performs during connection creation. It does this after the remote features have been successfully requested and before any pending authentication requests are performed. The code will work sub-optimally with userspace versions that still do the name requesting themselves (it shouldn't break anything though) so it is recommended to combine this with a userspace software version that doesn't have automated name requests.

2010-12-01net/ipv6/sit.c: return unhandled skb to tunnel4_rcvDavid McCullough
I found a problem using an IPv6 over IPv4 tunnel. When CONFIG_IPV6_SIT was enabled, the packets would be rejected as net/ipv6/sit.c was catching all IPPROTO_IPV6 packets and returning an ICMP port unreachable error. I think this patch fixes the problem cleanly. I believe the code in net/ipv4/tunnel4.c:tunnel4_rcv takes care of it properly if none of the handlers claim the skb.

2010-12-01Make the ip6_tunnel reflect the true mtu.Anders Franzen
The ip6_tunnel always assumes it consumes 40 bytes (ip6 hdr) of the mtu of the underlaying device. So for a normal ethernet bearer, the mtu of the ip6_tunnel is 1460. However, when creating a tunnel the encap limit option is enabled by default, and it consumes 8 bytes more, so the true mtu shall be 1452.

Remove a superfluous ieee80211_is_data check as that was checked a few lines before already and we wont't get here for non-data frames at all. Second, the frame was already converted to 802.3 header format and reading the fc and addr1 fields was only possible because the 802.3 header is short enough and didn't overwrite the relevant parts of the 802.11 header. Make the code more obvious by checking the ethernet header's h_dest field.
