Drivers, and perhaps other entities we have not yet considered, sometimes want to know how deep the protocol headers go before deciding how large of an SKB to allocate and how much of the packet to place into the linear SKB area. For example, consider a driver which has a device which DMAs into pools of pages and then tells the driver where the data went in the DMA descriptor(s). The driver can then build an SKB and reference most of the data via SKB fragments (which are page/offset/length triplets). However at least some of the front of the packet should be placed into the linear SKB area, which comes before the fragments, so that packet processing can get at the headers efficiently. The first thing each protocol layer is going to do is a "pskb_may_pull()" so we might as well aggregate as much of this as possible while we're building the SKB in the driver. Part of supporting this is that we don't have an SKB yet, so we want to be able to let the flow dissector operate on a raw buffer in order to compute the offset of the end of the headers. So now we have a __skb_flow_dissect() which takes an explicit data pointer and length. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Jon Maloy says: ==================== tipc: Merge port and socket layer code After the removal of the TIPC native interface, there is no reason to keep a distinction between a "generic" port layer and a "specific" socket layer in the code. Throughout the last months, we have posted several series that aimed at facilitating removal of the port layer, and in particular the port_lock spinlock, which in reality duplicates the role normally kept by lock_sock()/bh_lock_sock(). In this series, we finalize this work, by making a significant number of changes to the link, node, port and socket code, all with the aim of reducing dependencies between the layers. In the final commits, we then remove the port spinlock, port.c and port.h altogether. After this series, we have a socket layer that has only few dependencies to the rest of the stack, so that it should be possible to continue cleanups of its code without significantly affecting other code. ==================== Signed-off-by: NDavid S.

In previous commits we have reduced usage of port_lock to a minimum, and complemented it with usage of bh_lock_sock() at the remaining locations. The purpose has been to remove this lock altogether, since it largely duplicates the role of bh_lock_sock. We are now ready to do this. However, we still need to protect the BH callers from inadvertent release of the socket while they hold a reference to it. We do this by replacing port_lock by a combination of a rw-lock protecting the reference table as such, and updating the socket reference counter while the socket is referenced from BH. This technique is more standard and comprehensible than the previous approach, and turns out to have a positive effect on overall performance.

In order to make tipc_sock the only entity referencable from other parts of the stack, we add a tipc_sock pointer instead of a tipc_port pointer to the registry. As a consequence, we also let the function tipc_port_lock() return a pointer to a tipc_sock instead of a tipc_port. We keep the function's name for now, since the lock still is owned by the port. This is another step in the direction of eliminating port_lock, replacing its usage with lock_sock() and bh_lock_sock().

The functions tipc_port_get_ports() and tipc_port_reinit() scan over all sockets/ports to access each of them. This is done by using a dedicated linked list, 'tipc_socks' where all sockets are members. The list is in turn protected by a spinlock, 'port_list_lock', while each socket is locked by using port_lock at the moment of access. In order to reduce complexity and risk of deadlock, we want to get rid of the linked list and the accompanying spinlock. This is what we do in this commit. Instead of the linked list, we use the port registry to scan across the sockets. We also add usage of bh_lock_sock() inside the scope of port_lock in both functions, as a preparation for the complete removal of port_lock. Finally, we move the functions from port.c to socket.c, and rename them to tipc_sk_sock_show() and tipc_sk_reinit() repectively.

After the latest changes to the socket/port layer the existence of the functions tipc_port_init() and tipc_port_destroy() cannot be justified. They are both called only once, from tipc_sk_create() and tipc_sk_delete() respectively, and their functionality can better be merged into the latter two functions. This also entails that all remaining references to port_lock now are made from inside socket.c, something that will make it easier to remove this lock.

tipc_port_connect()/tipc_port_disconnect() are remnants of the obsolete native API. Their only task is to grab port_lock and call the functions __tipc_port_connect()/__tipc_port_disconnect() respectively, which will perform the actual state change. Since socket/port exection now is single-threaded the use of port_lock is not needed any more, so we can safely replace the two functions with their lock-free counterparts. In this commit, we remove the two functions. Furthermore, the contents of __tipc_port_disconnect() is so trivial that we choose to eliminate that function too, expanding its functionality into tipc_shutdown(). __tipc_port_connect() is simplified, moved to socket.c, and given the more correct name tipc_sk_finish_conn(). Finally, we eliminate the function auto_connect(), and expand its contents into filter_connect().

tipc_port_shutdown() is a remnant from the now obsolete native interface. As such it grabs port_lock in order to protect itself from concurrent BH processing. However, after the recent changes to the port/socket upcalls, sockets are now basically single-threaded, and all execution, except the read-only tipc_sk_timer(), is executing within the protection of lock_sock(). So the use of port_lock is not needed here. In this commit we eliminate the whole function, and merge it into its only caller, tipc_shutdown().

The last remaining BH upcall to the socket, apart for the message reception function tipc_sk_rcv(), is the timer function. We prefer to let this function continue executing in BH, since it only does read-acces to semi-permanent data, but we make three changes to it: 1) We introduce a bh_lock_sock()/bh_unlock_sock() inside the scope of port_lock. This is a preparation for replacing port_lock with bh_lock_sock() at the locations where it is still used. 2) We move the function from port.c to socket.c, as a further step of eliminating the port code level altogether. 3) We let it make use of the newly introduced tipc_msg_create() function.

In the current implementation, each 'struct tipc_node' instance keeps a linked list of those ports/sockets that are connected to the node represented by that struct. The purpose of this is to let the node object know which sockets to alert when it loses contact with its peer node, i.e., which sockets need to have their connections aborted. This entails an unwanted direct reference from the node structure back to the port/socket structure, and a need to grab port_lock when we have to make an upcall to the port. We want to get rid of this unecessary BH entry point into the socket, and also eliminate its use of port_lock. In this commit, we instead let the node struct keep list of "connected socket" structs, which each represents a connected socket, but is allocated independently by the node at the moment of connection. If the node loses contact with its peer node, the list is traversed, and a "connection abort" message is created for each entry in the list. The message is sent to it respective connected socket using the ordinary data path, and the receiving socket aborts its connections upon reception of the message. This enables us to get rid of the direct reference from 'struct node' to ´struct port', and another unwanted BH access point to the latter.

The current link implementation keeps a linked list of blocked ports/ sockets that is populated when there is link congestion. The purpose of this is to let the link know which users to wake up when the congestion abates. This adds unnecessary complexity to the data structure and the code, since it forces us to involve the link each time we want to delete a socket. It also forces us to grab the spinlock port_lock within the scope of node_lock. We want to get rid of this direct dependence, as well as the deadlock hazard resulting from the usage of port_lock. In this commit, we instead let the link keep list of a "wakeup" pseudo messages for use in such situations. Those messages are sent to the pending sockets via the ordinary message reception path, and wake up the socket's owner when they are received. This enables us to get rid of the 'waiting_ports' linked lists in struct tipc_port that manifest this direct reference. As a consequence, we can eliminate another BH entry into the socket, and hence the need to grab port_lock. This is a further step in our effort to remove port_lock altogether.

The function tipc_msg_init() has turned out to be of limited value in many cases. It take too few parameters to be usable for creating a complete message, it makes too many assumptions about what the message should be used for, and it does not allocate any buffer to be returned to the caller. Therefore, we now introduce the new function tipc_msg_create(), which takes all the parameters needed to create a full message, and returns a buffer of the requested size. The new function will be very useful for the changes we will be doing in later commits in this series.

Upon timeout, undo (via both timestamps/Eifel and DSACKs) was disabled if any retransmits were still in flight. The concern was perhaps that spurious retransmission sent in a previous recovery episode may trigger DSACKs to falsely undo the current recovery. However, this inadvertently misses undo opportunities (using either TCP timestamps or DSACKs) when timeout occurs during a loss episode, i.e. recurring timeouts or timeout during fast recovery. In these cases some retransmissions will be in flight but we should allow undo. Furthermore, we should only reset undo_marker and undo_retrans upon timeout if we are starting a new recovery episode. Finally, when we do reset our undo state, we now do so in a manner similar to tcp_enter_recovery(), so that we require a DSACK for each of the outstsanding retransmissions. This will achieve the original goal by requiring that we receive the same number of DSACKs as retransmissions. This patch increases the undo events by 50% on Google servers.
