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: NDavid Howells <dhowells@redhat.com> Signed-off-by: NDavid 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: NDavid Howells <dhowells@redhat.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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: NDavid Howells <dhowells@redhat.com> Signed-off-by: NDavid 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.

find_outdev calls inet{,6}_fib_lookup_dev() or dev_get_by_index() to find the output device. In case of an error, inet{,6}_fib_lookup_dev() returns error pointer and dev_get_by_index() returns NULL. But the function only checks for NULL and thus can end up calling dev_put on an ERR_PTR. This patch adds an additional check for err ptr after the NULL check.

Resetting a bearer/interface, with the consequence of resetting all its pertaining links, is not an atomic action. This becomes particularly evident in very large clusters, where a lot of traffic may happen on the remaining links while we are busy shutting them down. In extreme cases, we may even see links being re-created and re-established before we are finished with the job. To solve this, we now introduce a solution where we temporarily detach the bearer from the interface when the bearer is reset. This inhibits all packet reception, while sending still is possible. For the latter, we use the fact that the device's user pointer now is zero to filter out which packets can be sent during this situation; i.e., outgoing RESET messages only. This filtering serves to speed up the neighbors' detection of the loss event, and saves us from unnecessary probing.

When enabling a bearer we create a 'neigbor discoverer' instance by calling the function tipc_disc_create() before the bearer is actually registered in the list of enabled bearers. Because of this, the very first discovery broadcast message, created by the mentioned function, is lost, since it cannot find any valid bearer to use. Furthermore, the used send function, tipc_bearer_xmit_skb() does not free the given buffer when it cannot find a bearer, resulting in the leak of exactly one send buffer each time a bearer is enabled. This commit fixes this problem by introducing two changes: 1) Instead of attemting to send the discovery message directly, we let tipc_disc_create() return the discovery buffer to the calling function, tipc_enable_bearer(), so that the latter can send it when the enabling sequence is finished. 2) In tipc_bearer_xmit_skb(), as well as in the two other transmit functions at the bearer layer, we now free the indicated buffer or buffer chain when a valid bearer cannot be found.

This patch fixes an issue I found in which we were dropping frames if we had enabled checksums on GRE headers that were encapsulated by either FOU or GUE. Without this patch I was barely able to get 1 Gb/s of throughput. With this patch applied I am now at least getting around 6 Gb/s. The issue is due to the fact that with FOU or GUE applied we do not provide a transport offset pointing to the GRE header, nor do we offload it in software as the GRE header is completely skipped by GSO and treated like a VXLAN or GENEVE type header. As such we need to prevent the stack from generating it and also prevent GRE from generating it via any interface we create.

This patch adds GRO functions (gro_receive and gro_complete) to UDP sockets. udp_gro_receive is changed to perform socket lookup on a packet. If a socket is found the related GRO functions are called. This features obsoletes using UDP offload infrastructure for GRO (udp_offload). This has the advantage of not being limited to provide offload on a per port basis, GRO is now applied to whatever individual UDP sockets are bound to. This also allows the possbility of "application defined GRO"-- that is we can attach something like a BPF program to a UDP socket to perfrom GRO on an application layer protocol.

David Ahern reported panics in __inet_hash() caused by my recent commit. The reason is inet_reuseport_add_sock() was still using sk_nulls_for_each_rcu() instead of sk_for_each_rcu(). SO_REUSEPORT enabled listeners were causing an instant crash. While chasing this bug, I found that I forgot to clear SOCK_RCU_FREE flag, as it is inherited from the parent at clone time.

The check in vmci_transport_peer_detach_cb should only allow a detach when the qp handle of the transport matches the one in the detach message. Testing: Before this change, a detach from a peer on a different socket would cause an active stream socket to register a detach.

Trinity and other fuzzers can hit this WARN on far too easily, resulting in a tainted kernel that hinders automated fuzzing. Replace it with a rate-limited printk.

This fixes: net/mac80211/mesh_hwmp.c:603:26: warning: ‘target_metric’ may be used uninitialized in this function target_metric is only consumed when reply = true so no bug exists here, but not all versions of gcc realize it. Initialize to 0 to remove the warning. Signed-off-by: NJeff Mahoney <jeffm@suse.com> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

If the user space issues a NL80211_CMD_CONNECT with NL80211_ATTR_PREV_BSSID when there is already a connection, allow this to proceed as a reassociation instead of rejecting the new connect command with EALREADY.

This extends NL80211_CMD_CONNECT to allow the NL80211_ATTR_PREV_BSSID attribute to be used similarly to way this was already allowed with NL80211_CMD_ASSOCIATE. This allows user space to request reassociation (instead of association) when already connected to an AP. This provides an option to reassociate within an ESS without having to disconnect and associate with the AP.
