Eric W. Biederman says: ==================== Using dev_kfree_skb_any for functions called in multiple contexts This patchset should be an uncontroversial set of changes to change dev_kfree_skb to dev_kfree_skb_any for code paths that are called in hard irq contexts in addition to other contexts. netpoll is the reason this code gets called in multiple contexts. There is more coming but these changes are a good starting place, and stand on their own. Since the last round changes to the rx path have been removed netpoll will changed to avoid that. ==================== Signed-off-by:

netpoll can call functions in hard irq context that are ordinarily called in lesser contexts. For those functions use dev_kfree_skb_any and dev_consume_skb_any so skbs are freed safely from hard irq context. Signed-off-by:

Or Gerlitz says: ==================== mlx4: Add SRIOV support for RoCE This series adds SRIOV support for RoCE (RDMA over Ethernet) to the mlx4 driver. The patches are against net-next, as of commit 2d8d40af "pkt_sched: fq: do not hold qdisc lock while allocating memory" changes from V1: - addressed feedback from Dave on patch #3 and changed get_real_sgid_index() to be called fill_in_real_sgid_index() and be a void function. - removed some checkpatch warnings on long lines changes from V0: - always check the return code of mlx4_get_roce_gid_from_slave(). The call we fixed is introduced in patch #1 and later removed by patch #3 that allows guests to have multiple GIDS. The 1..3 separation was done for proper division of patches to logical changes. ==================== Signed-off-by:

To activate RoCE/SRIOV, need to remove the following: 1. In mlx4_ib_add, need to remove the error return preventing initialization of a RoCE port under SRIOV. 2. In update_vport_qp_params (in resource_tracker.c) need to remove the error return when a RoCE RC or UD qp is detected. This error return causes the INIT-to-RTR qp transition to fail in the wrapper function under RoCE/SRIOV. Signed-off-by:

Since there is no connection between the MAC/VLAN and the GID when using IP-based addressing, the proxy QP1 (running on the slave) must pass the source-mac, destination-mac, and vlan_id information separately from the GID. Additionally, the Host must pass the remote source-mac and vlan_id back to the slave, This is achieved as follows: Outgoing MADs: 1. Source MAC: obtained from the CQ completion structure (struct ib_wc, smac field). 2. Destination MAC: obtained from the tunnel header 3. vlan_id: obtained from the tunnel header. Incoming MADs 1. The source (i.e., remote) MAC and vlan_id are passed in the tunnel header to the proxy QP1. VST mode support: For outgoing MADs, the vlan_id obtained from the header is discarded, and the vlan_id specified by the Hypervisor is used instead. For incoming MADs, the incoming vlan_id (in the wc) is discarded, and the "invalid" vlan (0xffff) is substituted when forwarding to the slave.

The IB side of RoCE requires the MAC table index of the MAC address used by its QPs. To obtain the real MAC index, the IB side registers the MAC (increasing its ref count, and also returning the real MAC index) during the modify-qp sequence. This protects against the ETH side deleting or modifying that MAC table entry while the QP is active. Note that until the modify-qp command returns success, the MAC and VLAN information only has "candidate" status. If the modify-qp succeeds, the "candidate" info is promoted to the operational MAC/VLAN info for the qp. If the modify fails, the candidate MAC/VLAN is unregistered, and the old qp info is preserved. The patch is a bit complex, because there are multiple qp transitions where the primary-path information may be modified: INIT-to-RTR, and SQD-to-SQD. Similarly for the alternate path information. Therefore the code must handle cases where path information has already been entered into the QP context by previous qp transitions. For the MAC address, the success logic is as follows: 1. If there was no previous MAC, simply move the candidate MAC information to the operational information, and reset the candidate MAC info. 2. If there was a previous MAC, unregister it. Then move the MAC information from candidate to operational, and reset the candidate info (as in 1. above). The MAC address failure logic is the same for all cases: - Unregister the candidate MAC, and reset the candidate MAC info. For Vlan registration, the logic is similar. Signed-off-by:

The GIDs are statically distributed, as follows: PF: gets 16 GIDs VFs: Remaining GIDS are divided evenly between VFs activated by the driver. If the division is not even, lower-numbered VFs get an extra GID. For an IB interface, the number of gids per guest remains as before: one gid per guest. Signed-off-by: -

For IB transport, the host determines the slave GIDs. For ETH (RoCE), however, the slave's GID is determined by the IP address that the slave itself assigns to the ETH device used by RoCE. In this case, the slave must be able to write its GIDs to the HCA gid table (at the GID indices that slave "owns"). This commit adds processing for the SET_PORT_GID_TABLE opcode modifier for the SET_PORT command wrapper (so that slaves may modify their GIDS for RoCE). Signed-off-by:

This requires the following modifications: 1. Fix build_mlx4_header to properly fill in the ETH fields 2. Adjust mux and demux QP1 flow to support RoCE. This commit still assumes only one GID per slave for RoCE. The commit enabling multiple GIDs is a subsequent commit, and is done separately because of its complexity. Signed-off-by:

Jon Maloy says: ==================== tipc: simplifications in socket and port layer After the removal of the tipc native API the relation between tipc_port and its API types is strictly one-to-one, i.e, the latter can now only be a socket API. This change opens up for simplifications both in the code, data and locking structure. We start with this series, where we ensure that port and socket structures are co-allocated. Note that the first commit in the series is unrelated to the above. ==================== Signed-off-by: -

As an artefact from the native interface, the message sending functions in the port takes a port ref as first parameter, and then looks up in the registry to find the corresponding port pointer. This despite the fact that the only currently existing caller, tipc_sock, already knows this pointer. We change the signature of these functions to take a struct tipc_port* argument, and remove the redundant lookups. We also remove an unmotivated extra lookup in the function socket.c:auto_connect(), and, as the lookup functions tipc_port_deref() and ref_deref() now become unused, we remove these two functions.

The practice of naming variables in TIPC is inconistent, sometimes even within the same file. In this commit we align variable names and declarations within socket.c, and function and macro names within socket.h. We also reduce the number of conversion macros to two, in order to make usage less obsure. These changes are purely cosmetic. Signed-off-by:

Jon Paul Maloy authored
The three functions tipc_portimportance(), tipc_portunreliable() and tipc_portunreturnable() and their corresponding tipc_set* functions, are all grabbing port_lock when accessing the targeted port. This is unnecessary in the current code, since these calls only are made from within socket downcalls, already protected by sock_lock. We remove the redundant locking. Also, since the functions now become trivial one-liners, we move them to port.h and make them inline. Signed-off-by:

Due to the original one-to-many relation between port and user API layers, upcalls to the API have been performed via function pointers, installed in struct tipc_port at creation. Since this relation now always is one-to-one, we can instead use ordinary function calls. We remove the function pointers 'dispatcher' and ´wakeup' from struct tipc_port, and replace them with calls to the renamed functions tipc_sk_rcv() and tipc_sk_wakeup(). At the same time we change the name and signature of the functions tipc_createport() and tipc_deleteport() to reflect their new role as mere initialization/destruction functions. Signed-off-by:

After the removal of the tipc native API the relation between a tipc_port and its API types is strictly one-to-one, i.e, the latter can now only be a socket API. There is therefore no need to allocate struct tipc_port and struct sock independently. In this commit, we aggregate struct tipc_port into struct tipc_sock, hence saving both CPU cycles and structure complexity. There are no functional changes in this commit, except for the elimination of the separate allocation/freeing of tipc_port. All other changes are just adaptatons to the new data structure. This commit also opens up for further code simplifications and code volume reduction, something we will do in later commits. Signed-off-by:
