We forgot to set the error code on two error paths which means that we return ERR_PTR(0) which is NULL. The caller, find_and_alloc_map(), is not expecting that and will have a NULL dereference. Fixes: 546ac1ff ("bpf: add devmap, a map for storing net device references") Signed-off-by:

Merge tag 'rxrpc-rewrite-20170721' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Rearrange headers Here's a pair of patches that rearrange some of the AF_RXRPC header files that are outside of the net/rxrpc/ directory: (1) The bits userspace need are moved to uapi/linux/rxrpc.h. [Should this be af_rxrpc.h instead, I wonder - but there doesn't seem to be precedent for that in the other net UAPI headers.] (2) For the most part, the contents of rxrpc/packet.h are no longer used outside of the AF_RXRPC module, so move them to net/rxrpc/protocol.h with the exception of the standard abort codes which are exposed to userspace when an abort occurs and the security index values which are needed when constructing keys. ==================== Signed-off-by:

Sabrina Dubroca says: ==================== Allow to switch off UDP-based tunnel offloads per netdevice This patchset adds a new netdevice feature to toggle RX offloads of UDP-based tunnel via ethtool. This is useful if the offload is causing issues, for example if the hardware is buggy. The feature is added to all devices providing the ->ndo_udp_tunnel_add op, and enabled by default to preserve current behavior. When the administrator disables this feature on a device, all currently offloaded ports are cleared from the device. When the feature is turned on, the stack notifies the device about all current ports. v2: - rename feature bit to NETIF_F_RX_UDP_TUNNEL_PORT - rename ethtool feature to rx-udp_tunnel-port-offload ==================== Signed-off-by:

NETIF_F_RX_UDP_TUNNEL_PORT is special, in that we need to do more than just flip the bit in dev->features. When disabling we must also clear currently offloaded ports from the device, and when enabling we must tell the device to offload the ports it can. Because vxlan stores its sockets in a hashtable and they are inserted at the head of per-bucket lists, switching the feature off and then on can result in a different set of ports being offloaded (depending on the HW's limits).

This patch adds changelink rtnl operation support for geneve devices and the code changes involve: - added geneve_quiesce() which quiesces the geneve device data path for both TX and RX. This lets us perform the changelink operation atomically w.r.t data path. Also added geneve_unquiesce() to reverse the operation of geneve_quiesce(). - refactor geneve_newlink into geneve_nl2info to be used by both geneve_newlink and geneve_changelink - geneve_nl2info takes a changelink boolean argument to isolate changelink checks. - Allow changing only a few attributes (ttl, tos, and remote tunnel endpoint IP address (within the same address family)): - return -EOPNOTSUPP for attributes that cannot be changed for now. Incremental patches can make the non-supported one available in the future if needed. Signed-off-by:

Current XDP implementation wants guest offloads feature to be disabled on device. This is inconvenient and means guest can't benefit from offloads if XDP is not used. This patch tries to address this limitation by disabling the offloads on demand through control guest offloads. Guest offloads will be disabled and enabled on demand on XDP set. Signed-off-by:

We currently reset the device during XDP set, the main reason is that we allocate more headroom with XDP (for header adjustment). This works but causes network downtime for users. Previous patches encoded the headroom in the buffer context, this makes it possible to detect the case where a buffer with headroom insufficient for XDP is added to the queue and XDP is enabled afterwards. Upon detection, we handle this case by copying the packet (slow, but it's a temporary condition). Signed-off-by:

Move the protocol description header file into net/rxrpc/ and rename it to protocol.h. It's no longer necessary to expose it as packets are no longer exposed to kernel services (such as AFS) that use the facility.

balance-alb mode used to have transmit dynamic load balancing feature enabled by default. However, transmit dynamic load balancing no longer works in balance-alb after commit 8b426dc5 ("bonding: remove hardcoded value"). Both balance-tlb and balance-alb use the function bond_do_alb_xmit() to send packets. This function uses the parameter tlb_dynamic_lb. tlb_dynamic_lb used to have the default value of 1 for balance-alb, but now the value is set to 0 except in balance-tlb. Re-enable transmit dyanmic load balancing by initializing tlb_dynamic_lb for balance-alb similar to balance-tlb. Fixes: 8b426dc5 ("bonding: remove hardcoded value") Signed-off-by:
