2020-06-04inet_connection_sock: clear inet_num out of destroy helperPaolo Abeni
Clearing the 'inet_num' field is necessary and safe if and only if the socket is not bound. The MPTCP protocol calls the destroy helper on bound sockets, as tcp_v{4,6}_syn_recv_sock completed successfully. Move the clearing of such field out of the common code, otherwise the MPTCP MP_JOIN error path will find the wrong 'inet_num' value on socket disposal, __inet_put_port() will acquire the wrong lock and bind_node removal could race with other modifiers possibly corrupting the bind hash table.

2020-06-04seg6: fix seg6_validate_srh() to avoid slab-out-of-boundsAhmed Abdelsalam
The seg6_validate_srh() is used to validate SRH for three cases: case1: SRH of data-plane SRv6 packets to be processed by the Linux kernel. Case2: SRH of the netlink message received from user-space (iproute2) Case3: SRH injected into packets through setsockopt In case1, the SRH can be encoded in the Reduced way (i.e., first SID is carried in DA only and not represented as SID in the SRH) and the seg6_validate_srh() now handles this case correctly. In case2 and case3, the SRH shouldn’t be encoded in the Reduced way otherwise we lose the first segment (i.e., the first hop). The current implementation of the seg6_validate_srh() allow SRH of case2 and case3 to be encoded in the Reduced way. This leads a slab-out-of-bounds problem. This patch verifies SRH of case1, case2 and case3. Allowing case1 to be reduced while preventing SRH of case2 and case3 from being reduced .

2020-06-01bpf: Add link-based BPF program attachment to network namespaceJakub Sitnicki
Extend bpf() syscall subcommands that operate on bpf_link, that is LINK_CREATE, LINK_UPDATE, OBJ_GET_INFO, to accept attach types tied to network namespaces (only flow dissector at the moment). Link-based and prog-based attachment can be used interchangeably, but only one can exist at a time. Attempts to attach a link when a prog is already attached directly, and the other way around, will be met with -EEXIST. Attempts to detach a program when link exists result in -EINVAL. Attachment of multiple links of same attach type to one netns is not supported with the intention to lift the restriction when a use-case presents itself. Because of that link create returns -E2BIG when trying to create another netns link, when one already exists. Link-based attachments to netns don't keep a netns alive by holding a ref to it. Instead links get auto-detached from netns when the latter is being destroyed, using a pernet pre_exit callback. When auto-detached, link lives in defunct state as long there are open FDs for it. -ENOLINK is returned if a user tries to update a defunct link. Because bpf_link to netns doesn't hold a ref to struct net, special care is taken when releasing, updating, or filling link info. The netns might be getting torn down when any of these link operations are in progress. That is why auto-detach and update/release/fill_info are synchronized by the same mutex. Also, link ops have to always check if auto-detach has not happened yet and if netns is still alive (refcnt > 0).

2020-06-01net: Introduce netns_bpf for BPF programs attached to netnsJakub Sitnicki
In order to: (1) attach more than one BPF program type to netns, or (2) support attaching BPF programs to netns with bpf_link, or (3) support multi-prog attach points for netns we will need to keep more state per netns than a single pointer like we have now for BPF flow dissector program. Prepare for the above by extracting netns_bpf that is part of struct net, for storing all state related to BPF programs attached to netns. Turn flow dissector callbacks for querying/attaching/detaching a program into generic ones that operate on netns_bpf. Next patch will move the generic callbacks into their own module. This is similar to how it is organized for cgroup with cgroup_bpf.

2020-06-01bpf: Fix running sk_skb program types with ktlsJohn Fastabend
KTLS uses a stream parser to collect TLS messages and send them to the upper layer tls receive handler. This ensures the tls receiver has a full TLS header to parse when it is run. However, when a socket has BPF_SK_SKB_STREAM_VERDICT program attached before KTLS is enabled we end up with two stream parsers running on the same socket. The result is both try to run on the same socket. First the KTLS stream parser runs and calls read_sock() which will tcp_read_sock which in turn calls tcp_rcv_skb(). This dequeues the skb from the sk_receive_queue. When this is done KTLS code then data_ready() callback which because we stacked KTLS on top of the bpf stream verdict program has been replaced with sk_psock_start_strp(). This will in turn kick the stream parser again and eventually do the same thing KTLS did above calling into tcp_rcv_skb() and dequeuing a skb from the sk_receive_queue. At this point the data stream is broke. Part of the stream was handled by the KTLS side some other bytes may have been handled by the BPF side. Generally this results in either missing data or more likely a "Bad Message" complaint from the kTLS receive handler as the BPF program steals some bytes meant to be in a TLS header and/or the TLS header length is no longer correct. We've already broke the idealized model where we can stack ULPs in any order with generic callbacks on the TX side to handle this. So in this patch we do the same thing but for RX side. We add a sk_psock_strp_enabled() helper so TLS can learn a BPF verdict program is running and add a tls_sw_has_ctx_rx() helper so BPF side can learn there is a TLS ULP on the socket. Then on BPF side we omit calling our stream parser to avoid breaking the data stream for the KTLS receiver. Then on the KTLS side we call BPF_SK_SKB_STREAM_VERDICT once the KTLS receiver is done with the packet but before it posts the msg to userspace. This gives us symmetry between the TX and RX halfs and IMO makes it usable again. On the TX side we process packets in this order BPF -> TLS -> TCP and on the receive side in the reverse order TCP -> TLS -> BPF. Discovered while testing OpenSSL 3.0 Alpha2.0 release.

2020-06-01bridge: mrp: Add support for role MRAHoratiu Vultur
A node that has the MRA role, it can behave as MRM or MRC. Initially it starts as MRM and sends MRP_Test frames on both ring ports. If it detects that there are MRP_Test send by another MRM, then it checks if these frames have a lower priority than itself. In this case it would send MRP_Nack frames to notify the other node that it needs to stop sending MRP_Test frames. If it receives a MRP_Nack frame then it stops sending MRP_Test frames and starts to behave as a MRC but it would continue to monitor the MRP_Test frames send by MRM. If at a point the MRM stops to send MRP_Test frames it would get the MRM role and start to send MRP_Test frames. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S.

2020-06-01net: flow_offload: consolidate indirect flow_block infrastructurePablo Neira Ayuso
Tunnel devices provide no dev->netdev_ops->ndo_setup_tc(...) interface. The tunnel device and route control plane does not provide an obvious way to relate tunnel and physical devices. This patch allows drivers to register a tunnel device offload handler for the tc and netfilter frontends through flow_indr_dev_register() and flow_indr_dev_unregister(). The frontend calls flow_indr_dev_setup_offload() that iterates over the list of drivers that are offering tunnel device hardware offload support and it sets up the flow block for this tunnel device. If the driver module is removed, the indirect flow_block ends up with a stale callback reference. The module removal path triggers the dev_shutdown() path to remove the qdisc and the flow_blocks for the physical devices. However, this is not useful for tunnel devices, where relation between the physical and the tunnel device is not explicit. This patch introduces a cleanup callback that is invoked when the driver module is removed to clean up the tunnel device flow_block. This patch defines struct flow_block_indr and it uses it from flow_block_cb to store the information that front-end requires to perform the flow_block_cb cleanup on module removal.

2020-05-31cfg80211: add and expose HE 6 GHz band capabilitiesJohannes Berg
These capabilities cover what would otherwise be transported in HT/VHT capabilities, but only a subset thereof that is actually needed on 6 GHz with HE already present. Expose the capabilities to userspace, drivers are expected to set them as using the 6 GHz band (currently) requires HE capability.

now that can be done conveniently - all non-trivial cases have _HAVE_ARCH_COPY_AND_CSUM_FROM_USER defined, so the fallback in net/checksum.h is used only for dummy (copy_from_user, then csum_partial) implementation.
