2011-03-12ipv4: Pass ipv4 flow objects into fib_lookup() paths.David S. Miller2-3/+11
To start doing these conversions, we need to add some temporary flow4_* macros which will eventually go away when all the protocol code paths are changed to work on AF specific flowi objects. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Add flowiX_to_flowi() shorthands.David S. Miller1-0/+15
This is just a shorthand which will help in passing around AF specific flow structures as generic ones. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Break struct flowi out into AF specific instances.David S. Miller2-59/+59
Now we have struct flowi4, flowi6, and flowidn for each address family. And struct flowi is just a union of them all. It might have been troublesome to convert flow_cache_uli_match() but as it turns out this function is completely unused and therefore can be simply removed. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Make flowi ports AF dependent.David S. Miller3-36/+46
Create two sets of port member accessors, one set prefixed by fl4_* and the other prefixed by fl6_* This will let us to create AF optimal flow instances. It will work because every context in which we access the ports, we have to be fully aware of which AF the flowi is anyways. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Create union flowi_uliDavid S. Miller1-23/+25
This will be used when we have seperate flowi types. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Create struct flowi_commonDavid S. Miller1-9/+21
Pull out the AF independent members of struct flowi into a new struct flowi_common Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Put flowi_* prefix on AF independent members of struct flowiDavid S. Miller4-33/+33
I intend to turn struct flowi into a union of AF specific flowi structs. There will be a common structure that each variant includes first, much like struct sock_common. This is the first step to move in that direction. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12net: Remove unnecessary padding in struct flowiDavid S. Miller1-10/+10
Move tos, scope, proto, and flags to the beginning of the structure. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-12ipv4: Create and use route lookup helpers.David S. Miller1-0/+48
The idea here is this minimizes the number of places one has to edit in order to make changes to how flows are defined and used. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-09Phonet: allocate sock from accept syscall rather than soft IRQRémi Denis-Courmont1-1/+0
This moves most of the accept logic to process context like other socket stacks do. Then we can use a few more common socket helpers and simplify a bit. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-08ipv4: Fix scope value used in route src-address caching.David S. Miller1-0/+1
We have to use cfg->fc_scope not the final nh_scope value. Reported-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S. Miller <davem@davemloft.net>
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 <davem@davemloft.net>

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 - 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: Normalize arguments to ip6_dst_blackhole().David S. Miller1-3/+2

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 <davem@davemloft.net>
2011-03-01udp: Switch to ip_finish_skbHerbert Xu2-0/+23
This patch converts UDP to use the new ip_finish_skb API. This would then allows us to more easily use ip_make_skb which allows UDP to run without a socket lock.

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.

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.
