Move all shared mem code to bnx2x to avoid code duplication. bnx2x now performs: - Read the FCoE and iSCSI max connection information. - Read the iSCSI and FCoE MACs from NPAR configuration in shmem. - Block the CNIC for the current function if there is neither FCoE nor iSCSI valid configuration by returning NULL from bnx2x_cnic_probe().

Both fib_trie and fib_hash have a local implementation of fib_table_select_default(). This is completely unnecessary code duplication. Since we now remember the fib_table and the head of the fib alias list of the default route, we can implement one single generic version of this routine. Looking at the fib_hash implementation you may get the impression that it's possible for there to be multiple top-level routes in the table for the default route. The truth is, it isn't, the insert code will only allow one entry to exist in the zero prefix hash table, because all keys evaluate to zero and all keys in a hash table must be unique.

This will be used later to implement fib_select_default() in a completely generic manner, instead of the current situation where the default route is re-looked up in the TRIE/HASH table and then the available aliases are analyzed. Signed-off-by: David S. Miller <davem@davemloft.net>

The routing algorithm must be able to decide if a fragment can be merged with the missing part and still be passed to a forwarding interface. The fragments can only differ by one byte in case that the original payload had an uneven length. In that situation the sender has to inform all possible receivers that the tail is one byte longer using the flag UNI_FRAG_LARGETAIL. The combination of UNI_FRAG_LARGETAIL and UNI_FRAG_HEAD flag makes it possible to calculate the correct length for even and uneven sized payloads. The original formula missed to add the unicast header at all and forgot to remove the fragment header of the second fragment. This made the results highly unreliable and only useful for machines with large differences between the configured MTUs.

The routing algorithm must know how large two fragments are to be able to decide that it is safe to merge them or if it should resubmit without waiting for the second part. When these two fragments have a too different size, it is not possible to guess right in every situation. The user could easily configure the MTU of the attached cards so that one fragment is forwarded and the other one is added to the fragments table to wait for the missing part. For even sized packets, it is possible to split it so that the resulting packages are equal sized by ignoring the old non-fragment header at the beginning of the original packet. This still creates different sized fragments for uneven sized packets.

The batman-adv vis server has to a stack which stores all information about packets which should be send later. This stack is protected with a spinlock that is used to prevent concurrent write access to it. The send_vis_packets function has to take all elements from the stack and send them to other hosts over the primary interface. The send will be initiated without the lock which protects the stack. The implementation using list_for_each_entry_safe has the problem that it stores the next element as "safe ptr" to allow the deletion of the current element in the list. The list may be modified during the unlock/lock pair in the loop body which may make the safe pointer not pointing to correct next element. It is safer to remove and use the first element from the stack until no elements are available. This does not need reduntant information which would have to be validated each time the lock was removed.

SIOCGETSGCNT is not a unique ioctl value as it it maps tio SIOCPROTOPRIVATE +1, which unfortunately means the existing infrastructure for compat networking ioctls is insufficient. A trivial compact ioctl implementation would conflict with: SIOCAX25ADDUID SIOCAIPXPRISLT SIOCGETSGCNT_IN6 SIOCGETSGCNT SIOCRSSCAUSE SIOCX25SSUBSCRIP SIOCX25SDTEFACILITIES To make this work I have updated the compat_ioctl decode path to mirror the the normal ioctl decode path. I have added an ipv4 inet_compat_ioctl function so that I can have ipv4 specific compat ioctls. I have added a compat_ioctl function into struct proto so I can break out ioctls by which kind of ip socket I am using. I have added a compat_raw_ioctl function because SIOCGETSGCNT only works on raw sockets. I have added a ipmr_compat_ioctl that mirrors the normal ipmr_ioctl. This was necessary because unfortunately the struct layout for the SIOCGETSGCNT has unsigned longs in it so changes between 32bit and 64bit kernels. This change was sufficient to run a 32bit ip multicast routing daemon on a 64bit kernel. Reported-by: Bill Fenner <fenner@aristanetworks.com> Signed-off-by: Eric W.

Biederman <ebiederm@aristanetworks.com> Date: Sun Nov 8 00:53:51 2009 -0800 net: Support specifying the network namespace upon device creation. There is no good reason to not support userspace specifying the network namespace during device creation, and it makes it easier to create a network device and pass it to a child network namespace with a well known name. We have to be careful to ensure that the target network namespace for the new device exists through the life of the call. To keep that logic clear I have factored out the network namespace grabbing logic into rtnl_link_get_net. In addtion we need to continue to pass the source network namespace to the rtnl_link_ops.newlink method so that we can find the base device source network namespace. Signed-off-by: Eric W.

On older kernels the VLAN code may zero skb->dev before dropping it and causing it to be reused by GRO. Unfortunately we didn't reset skb->dev in that case which causes the next GRO user to get a bogus skb->dev pointer. This particular problem no longer happens with the current upstream kernel due to changes in VLAN processing. However, for correctness we should still reset the skb->dev pointer in the GRO reuse function in case a future user does the same thing.
