David Howells says: ==================== RxRPC: 2nd rewrite part 1 Okay, I'm in the process of rewriting the RxRPC rewrite. The primary aim of this second rewrite is to strictly control the number of active connections we know about and to get rid of connections we don't need much more quickly. On top of this, there are fixes to the protocol handling which will all occur in later parts. Here's the first set of patches from the second go, aimed at net-next. These are all fixes and cleanups preparatory to the main event. Notable parts of this set include: (1) A fix for the AFS filesystem to wait for outstanding calls to complete before closing the RxRPC socket. (2) Differentiation of local and remote abort codes. At a future point userspace will get to see this via control message data on recvmsg(). (3) Absorb the rxkad module into the af_rxrpc module to prevent a dependency loop. (4) Create a null security module and unconditionalise calls into the security module that's in force (there will always be a security module applied to a connection, even if it's just the null one). ==================== Signed-off-by: David S.

Create a null security type for security index 0 and get rid of all conditional calls to the security operations. We expect normally to be using security, so this should be of little negative impact.

Absorb the rxkad security module into the af_rxrpc module so that there's only one module file. This avoids a circular dependency whereby rxkad pins af_rxrpc and cached connections pin rxkad but can't be manually evicted (they will expire eventually and cease pinning). With this change, af_rxrpc can just be unloaded, despite having cached connections. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Don't assume transport address family and size when using the peer address to send a packet. Instead, use the start of the transport address rather than any particular element of the union and use the transport address length noted inside the sockaddr_rxrpc struct. This will be necessary when IPv6 support is introduced. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Don't pass gfp around in incoming call handling functions, but rather hard code it at the points where we actually need it since the value comes from within the rxrpc driver and is always the same.

David Howells authored
In the rxrpc_connection and rxrpc_call structs, there's one field to hold the abort code, no matter whether that value was generated locally to be sent or was received from the peer via an abort packet. Split the abort code fields in two for cleanliness sake and add an error field to hold the Linux error number to the rxrpc_call struct too (sometimes this is generated in a context where we can't return it to userspace directly). Furthermore, add a skb mark to indicate a packet that caused a local abort to be generated so that recvmsg() can pick up the correct abort code. A future addition will need to be to indicate to userspace the difference between aborts via a control message. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S.

The afs filesystem needs to wait for any outstanding asynchronous calls (such as FS.GiveUpCallBacks cleaning up the callbacks lodged with a server) to complete before closing the AF_RXRPC socket when unloading the module. This may occur if the module is removed too quickly after unmounting all filesystems. This will produce an error report that looks like: AFS: Assertion failed 1 == 0 is false 0x1 == 0x0 is false ------------[ cut here ]------------ kernel BUG at ../fs/afs/rxrpc.c:135! ...

Willem de Bruijn says: ==================== net: fix udp pull header breakage Commit e6afc8ac ("udp: remove headers from UDP packets before queueing") modified udp receive processing to pull headers before enqueue and to not expect them on dequeue. The patch missed protocols on top of udp with in-kernel implementations that have their own skb_recv_datagram calls and dequeue logic. Modify these datapaths to also no longer expect a udp header at skb->data. Sunrpc and rxrpc are the only two protocols that call this function and contain references to udphr (some others, like tipc, are based on encap_rcv, which acts before enqueue, before the the header pull). ==================== Signed-off-by: David S.

Multipath route lookups should consider knowledge about next hops and not select a hop that is known to be failed. Example: [h2] [h3] 15.0.0.5 | | 3| 3| [SP1] [SP2]--+ 1 2 1 2 | | /-------------+ | | \ / | | X | | / \ | | / \---------------\ | 1 2 1 2 12.0.0.2 [TOR1] 3-----------------3 [TOR2] 12.0.0.3 4 4 \ / \ / \ / -------| |-----/ 1 2 [TOR3] 3| | [h1] 12.0.0.1 host h1 with IP 12.0.0.1 has 2 paths to host h3 at 15.0.0.5: root@h1:~# ip ro ls ... 12.0.0.0/24 dev swp1 proto kernel scope link src 12.0.0.1 15.0.0.0/16 nexthop via 12.0.0.2 dev swp1 weight 1 nexthop via 12.0.0.3 dev swp1 weight 1 ... If the link between tor3 and tor1 is down and the link between tor1 and tor2 then tor1 is effectively cut-off from h1. Yet the route lookups in h1 are alternating between the 2 routes: ping 15.0.0.5 gets one and ssh 15.0.0.5 gets the other. Connections that attempt to use the 12.0.0.2 nexthop fail since that neighbor is not reachable: root@h1:~# ip neigh show ... 12.0.0.3 dev swp1 lladdr 00:02:00:00:00:1b REACHABLE 12.0.0.2 dev swp1 FAILED ... The failed path can be avoided by considering known neighbor information when selecting next hops. If the neighbor lookup fails we have no knowledge about the nexthop, so give it a shot. If there is an entry then only select the nexthop if the state is sane. This is similar to what fib_detect_death does. To maintain backward compatibility use of the neighbor information is based on a new sysctl, fib_multipath_use_neigh.

The host_port field is constantly assigned to 0 and this value has never changed (since time when cpsw driver was introduced. More over, if this field will be assigned to non 0 value it will break current driver functionality. Hence, there are no reasons to continue maintaining this host_port field and it can be removed, and the HOST_PORT_NUM and ALE_PORT_HOST defines can be used instead.

ALE APIs expect to receive port masks as input values for arguments port_mask, untag, reg_mcast, unreg_mcast. But there are few places in code where port masks are passed left-shifted by cpsw_priv->host_port, like below: cpsw_ale_add_vlan(priv->ale, priv->data.default_vlan, ALE_ALL_PORTS << priv->host_port, ALE_ALL_PORTS << priv->host_port, 0, 0); and cpsw is still working just because priv->host_port == 0 and has never ever been changed. Hence, fix port_mask parameters in ALE APIs calls and drop "<< priv->host_port" from all places where it's used to shift valid port mask.

verifier is using the following structure to track the state of registers: struct reg_state { enum bpf_reg_type type; union { int imm; struct bpf_map *map_ptr; }; }; and later on in states_equal() does memcmp(&old->regs[i], &cur->regs[i],..) to find equivalent states. Throughout the code of verifier there are assignements to 'imm' and 'map_ptr' fields and it's not obvious that most of the assignments into 'imm' don't need to clear extra 4 bytes (like mark_reg_unknown_value() does) to make sure that memcmp doesn't go over junk left from 'map_ptr' assignment.

Enables the use of multiple transmit and receive scrqs allowing the ibmvnic driver to take advantage of multiqueue functionality. To achieve this, the driver must implement the process of negotiating the maximum number of queues allowed by the server. Initially, the driver will attempt to login with the maximum number of tx and rx queues supported by the server. If the server fails to allocate the requested number of scrqs, it will return partial success in the login response. In this case, we must reinitiate the login process from the request capabilities stage and attempt to login requesting fewer scrqs.
