2011-03-07ipv4: Cache source address in nexthop entries.David S. Miller1-2/+5
When doing output route lookups, we have to select the source address if the user has not specified an explicit one. First, if the route has an explicit preferred source address specified, then we use that. Otherwise we search the route's outgoing interface for a suitable address. This search can be precomputed and cached at route insertion time. The only missing part is that we have to refresh this precomputed value any time addresses are added or removed from the interface, and this is accomplished by fib_update_nh_saddrs().

2011-03-04ipv4: Remove flowi from struct rtable.David S. Miller1-9/+13
The only necessary parts are the src/dst addresses, the interface indexes, the TOS, and the mark. The rest is unnecessary bloat, which amounts to nearly 50 bytes on 64-bit. Signed-off-by: David S. Miller <[email protected]>

2011-03-03net_sched: reduce fifo qdisc sizeEric Dumazet1-0/+1
Because of various alignements [SLUB / qdisc], we use 512 bytes of memory for one {p|b}fifo qdisc, instead of 256 bytes on 64bit arches and 192 bytes on 32bit ones. Move the "u32 limit" inside "struct Qdisc" (no impact on other qdiscs) Change qdisc_alloc(), first trying a regular allocation before an oversized one.

2011-03-02dcbnl: add support for retrieving peer configuration - ceeShmulik Ravid1-0/+3

2011-03-02dcbnl: add support for retrieving peer configuration - ieeeShmulik Ravid1-0/+6
These 2 patches add the support for retrieving the remote or peer DCBX configuration via dcbnl for embedded DCBX stacks. The peer configuration is part of the DCBX MIB and is useful for debugging and diagnostics of the overall DCB configuration. The first patch add this support for IEEE 802.1Qaz standard the second patch add the same support for the older CEE standard. Diff for v2 - the peer-app-info is CEE specific.

2011-03-01ipv6: Consolidate route lookup sequences.David S. Miller1-3/+8
Route lookups follow a general pattern in the ipv6 code wherein we first find the non-IPSEC route, potentially override the flow destination address due to ipv6 options settings, and then finally make an IPSEC search using either xfrm_lookup() or __xfrm_lookup(). __xfrm_lookup() is used when we want to generate a blackhole route if the key manager needs to resolve the IPSEC rules (in this case -EREMOTE is returned and the original 'dst' is left unchanged). Otherwise plain xfrm_lookup() is used and when asynchronous IPSEC resolution is necessary, we simply fail the lookup completely. All of these cases are encapsulated into two routines, ip6_dst_lookup_flow and ip6_sk_dst_lookup_flow. The latter of which handles unconnected UDP datagram sockets. Signed-off-by: David S. Miller <[email protected]>
2011-03-01udp: Switch to ip_finish_skbHerbert Xu2-0/+23

2011-03-01inet: Add ip_make_skb and ip_finish_skbHerbert Xu1-0/+16
This patch adds the helper ip_make_skb which is like ip_append_data and ip_push_pending_frames all rolled into one, except that it does not send the skb produced. The sending part is carried out by ip_send_skb, which the transport protocol can call after it has tweaked the skb. It is meant to be called in cases where corking is not used should have a one-to-one correspondence to sendmsg. This patch also adds the helper ip_finish_skb which is meant to be replace ip_push_pending_frames when corking is required. Previously the protocol stack would peek at the socket write queue and add its header to the first packet. With ip_finish_skb, the protocol stack can directly operate on the final skb instead, just like the non-corking case with ip_make_skb.

2011-03-01inet: Remove explicit write references to sk/inet in ip_append_dataHerbert Xu1-9/+14
In order to allow simultaneous calls to ip_append_data on the same socket, it must not modify any shared state in sk or inet (other than those that are designed to allow that such as atomic counters). This patch abstracts out write references to sk and inet_sk in ip_append_data and its friends so that we may use the underlying code in parallel.

2011-02-25mac80211: support direct offchannel TX offloadJohannes Berg1-0/+10
For devices supported by iwlwifi sometimes off-channel transmissions need to be handled by the device completely. To support this mac80211 needs to pass the frame directly to the driver and not through the TX path as the driver needs the frame and channel information at the same time.

2011-02-25mac80211: make tx() operation return voidJohannes Berg1-1/+1
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

2011-02-24ipv4: Rearrange how ip_route_newports() gets port keys.David S. Miller1-8/+11
ip_route_newports() is the only place in the entire kernel that cares about the port members in the routing cache entry's lookup flow key. Therefore the only reason we store an entire flow inside of the struct rtentry is for this one special case. Rewrite ip_route_newports() such that: 1) The caller passes in the original port values, so we don't need to use the rth->fl.fl_ip_{s,d}port values to remember them. 2) The lookup flow is constructed by hand instead of being copied from the routing cache entry's flow.
