Since we've added support for IFLA_IF_NETNSID for RTM_{DEL,GET,SET,NEW}LINK it is possible for userspace to send us requests with three different properties to identify a target network namespace. This affects at least RTM_{NEW,SET}LINK. Each of them could potentially refer to a different network namespace which is confusing. For legacy reasons the kernel will pick the IFLA_NET_NS_PID property first and then look for the IFLA_NET_NS_FD property but there is no reason to extend this type of behavior to network namespace ids. The regression potential is quite minimal since the rtnetlink requests in question either won't allow IFLA_IF_NETNSID requests before 4.16 is out (RTM_{NEW,SET}LINK) or don't support IFLA_NET_NS_{PID,FD} (RTM_{DEL,GET}LINK) in the first place.

When using devmap to redirect packets between interfaces, xdp_do_flush() is usually a must to flush any batched packets. Unfortunately this is missed in current tuntap implementation. Unlike most hardware driver which did XDP inside NAPI loop and call xdp_do_flush() at then end of each round of poll. TAP did it in the context of process e.g tun_get_user(). So fix this by count the pending redirected packets and flush when it exceeds NAPI_POLL_WEIGHT or MSG_MORE was cleared by sendmsg() caller. With this fix, xdp_redirect_map works again between two TAPs. Fixes: 761876c8 ("tap: XDP support") Signed-off-by:

Nowadays, nlmsg_multicast() returns only 0 or -ESRCH but this was not the case when commit 134e6375 was pushed. However, there was no reason to stop the loop if a netns does not have listeners. Returns -ESRCH only if there was no listeners in all netns. To avoid having the same problem in the future, I didn't take the assumption that nlmsg_multicast() returns only 0 or -ESRCH.

Jakub Kicinski says: ==================== nfp: fix disabling TC offloads in flower, max TSO segs and module version This set corrects the way nfp deals with the NETIF_F_HW_TC flag. It has slipped the review that flower offload does not currently refuse disabling this flag when filter offload is active. nfp's flower offload does not actually keep track of how many filters for each port are offloaded. The accounting of the number of filters is added to the nfp core structures, and BPF moved to use these structures as well. If users are allowed to disable TC offloads while filters are active, not only is it incorrect behaviour, but actually the NFP will never be told to remove the flows, leading to use-after-free when stats arrive. Fourth patch makes sure we declare the max number of TSO segments. FW should drop longer packets cleanly (otherwise this would be a security problem for untrusted VFs) but dropping longer TSO frames is not nice and driver should prevent them from being generated. Last small addition populates MODULE_VERSION with kernel version. ==================== Signed-off-by: -

DKMS and similar out-of-tree module replacement services use module version to make sure the out-of-tree software is not older than the module shipped with the kernel. We use the kernel version in ethtool -i output, put it into MODULE_VERSION as well. Reported-by:

All netdevs which can accept TC offloads must implement .ndo_set_features(). nfp_reprs currently do not do that, which means hw-tc-offload can be turned on and off even when offloads are active. Whether the offloads are active is really a question to nfp_ports, so remove the per-app tc_busy callback indirection thing, and simply count the number of offloaded items in nfp_port structure.

Jakub Kicinski authored
nfp_port is a structure which represents an ASIC port, both PCIe vNIC (on a PF or a VF) or the external MAC port. vNIC netdev (struct nfp_net) and pure representor netdev (struct nfp_repr) both have a pointer to this structure. nfp_reprs always have a port associated. nfp_nets, however, only represent a device port in legacy mode, where they are considered the MAC port. In switchdev mode they are just the CPU's side of the PCIe link. By definition TC offloads only apply to device ports. Don't set the flag on vNICs without a port (i.e. in switchdev mode).

Upcoming changes will require all netdevs supporting TC offloads to have a full struct nfp_port. Require those for BPF offload. The operation without management FW reporting information about Ethernet ports is something we only support for very old and very basic NIC firmwares anyway. Signed-off-by:

It was discovered that simple program which indefinitely sends 200b UDP packets and runs on TI AM574x SoC (SMP) under RT Kernel triggers network watchdog timeout in TI CPSW driver (<6 hours run). The network watchdog timeout is triggered due to race between cpsw_ndo_start_xmit() and cpsw_tx_handler() [NAPI] cpsw_ndo_start_xmit() if (unlikely(!cpdma_check_free_tx_desc(txch))) { txq = netdev_get_tx_queue(ndev, q_idx); netif_tx_stop_queue(txq); ^^ as per [1] barier has to be used after set_bit() otherwise new value might not be visible to other cpus } cpsw_tx_handler() if (unlikely(netif_tx_queue_stopped(txq))) netif_tx_wake_queue(txq); and when it happens ndev TX queue became disabled forever while driver's HW TX queue is empty. Fix this, by adding smp_mb__after_atomic() after netif_tx_stop_queue() calls and double check for free TX descriptors after stopping ndev TX queue - if there are free TX descriptors wake up ndev TX queue.

Because of differences in how ipv4 and ipv6 handle fib lookups, verification of nexthops with onlink flag need to default to the main table rather than the local table used by IPv4. As it stands an address within a connected route on device 1 can be used with onlink on device 2. Updating the table properly rejects the route due to the egress device mismatch. Update the extack message as well to show it could be a device mismatch for the nexthop spec. Fixes: fc1e64e1 ("net/ipv6: Add support for onlink flag") Signed-off-by:

AF_RXRPC is incorrectly sending back to the server any abort it receives for a client connection. This is due to the final-ACK offload to the connection event processor patch. The abort code is copied into the last-call information on the connection channel and then the event processor is set. Instead, the following should be done: (1) In the case of a final-ACK for a successful call, the ACK should be scheduled as before. (2) In the case of a locally generated ABORT, the ABORT details should be cached for sending in response to further packets related to that call and no further action scheduled at call disconnect time. (3) In the case of an ACK received from the peer, the call should be considered dead, no ABORT should be transmitted at this time. In response to further non-ABORT packets from the peer relating to this call, an RX_USER_ABORT ABORT should be transmitted. (4) In the case of a call killed due to network error, an RX_USER_ABORT ABORT should be cached for transmission in response to further packets, but no ABORT should be sent at this time.

Fix this resource leak by scheduling removal of all entries and explicit call to the garbage collector. 10) nf_ct_nat_offset() declaration is dead code, this function prototype is not used anywhere, remove it.

flow_offload_del frees the flow, so all associated resource must be freed before. Since the ct entry in struct flow_offload_entry was allocated by flow_offload_alloc, it should be freed by flow_offload_free to take care of the error handling path when flow_offload_add fails.

The pipe buffer limits are accessed without any locking, and may be changed at any time by the sysctl handlers. In theory this could cause problems for expressions like the following: pipe_user_pages_hard && user_bufs > pipe_user_pages_hard ... since the assembly code might reference the 'pipe_user_pages_hard' memory location multiple times, and if the admin removes the limit by setting it to 0, there is a very brief window where processes could incorrectly observe the limit to be exceeded. Fix this by loading the limits with READ_ONCE() prior to use. Link: http://lkml.kernel.org/r/20180111052902.14409-8-ebiggers3@gmail.comSigned-off-by:Eric Biggers <ebiggers@google.com> Acked-by:
