If a device has self-managed regulatory, insist on returning the wiphy specific regdomain if a wiphy-idx is specified. The global regdomain is meaningless for such devices.

Add a new regulatory flag that allows a driver to manage regdomain changes/updates for its own wiphy. A self-managed wiphys only employs regulatory information obtained from the FW and driver and does not use other cfg80211 sources like beacon-hints, country-code IEs and hints from other devices on the same system. Conversely, a self-managed wiphy does not share its regulatory hints with other devices in the system. If a system contains several devices, one or more of which are self-managed, there might be contradictory regulatory settings between them. Usage of flag is generally discouraged. Only use it if the FW/driver is incompatible with non-locally originated hints. A new API lets the driver send a complete regdomain, to be applied on its wiphy only. After a wiphy-specific regdomain change takes place, usermode will get a new type of change notification. The regulatory core also takes care enforce regulatory restrictions, in case some interfaces are on forbidden channels.

If a wiphy-idx is specified, the kernel will return the wiphy specific regdomain, if such exists. Otherwise return the global regdom. When no wiphy-idx is specified, return the global regdomain as well as all wiphy-specific regulatory domains in the system, via a new nested list of attributes. Add a new attribute for each wiphy-specific regdomain, for usermode to identify it as such.

There have been several times where I have had to rebuild a kernel to cause a panic when hitting a WARN() in the code in order to get a crash dump from a system. Sometimes this is easy to do, other times (such as in the case of a remote admin) it is not trivial to send new images to the user. A much easier method would be a switch to change the WARN() over to a panic. This makes debugging easier in that I can now test the actual image the WARN() was seen on and I do not have to engage in remote debugging. This patch adds a panic_on_warn kernel parameter and /proc/sys/kernel/panic_on_warn calls panic() in the warn_slowpath_common() path. The function will still print out the location of the warning. An example of the panic_on_warn output: The first line below is from the WARN_ON() to output the WARN_ON()'s location. After that the panic() output is displayed.

virtio 1.0 modified virtio net header format, making all fields little endian. Users can tweak header format before submitting it to tun, but this means more data copies where none were necessary. And if the iovec is in RO memory, this means we might need to split iovec also means we might in theory overflow iovec max size. This patch adds a simpler way for applications to handle this, using new "little endian" flag in tun. As a result, tun simply byte-swaps header fields as appropriate. This is a NOP on LE architectures. Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

This patch extends the set/get_rxfh ethtool-options for getting or setting the RSS hash function. It modifies drivers implementation of set/get_rxfh accordingly. This change also delegates the responsibility of checking whether a modification to a certain RX flow hash parameter is supported to the driver implementation of set_rxfh. User-kernel API is done through the new hfunc bitmask field in the ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an index in the new string-set ETH_SS_RSS_HASH_FUNCS. Got approval from most of the relevant driver maintainers that their driver is using Toeplitz, and for the few that didn't answered, also assumed it is Toeplitz.

Allow reading of timestamps and cmsg at the same time on all relevant socket families. One use is to correlate timestamps with egress device, by asking for cmsg IP_PKTINFO. on AF_INET sockets, call the relevant function (ip_cmsg_recv). To avoid changing legacy expectations, only do so if the caller sets a new timestamping flag SOF_TIMESTAMPING_OPT_CMSG. on AF_INET6 sockets, IPV6_PKTINFO and all other recv cmsg are already returned for all origins. only change is to set ifindex, which is not initialized for all error origins. In both cases, only generate the pktinfo message if an ifindex is known. This is not the case for ACK timestamps. The difference between the protocol families is probably a historical accident as a result of the different conditions for generating cmsg in the relevant ip(v6)_recv_error function: ipv4: if (serr->ee.ee_origin == SO_EE_ORIGIN_ICMP) { ipv6: if (serr->ee.ee_origin != SO_EE_ORIGIN_LOCAL) { At one time, this was the same test bar for the ICMP/ICMP6 distinction. This is no longer true. Signed-off-by: NWillem de Bruijn <willemb@google.com> ---- Changes v1 -> v2 large rewrite - integrate with existing pktinfo cmsg generation code - on ipv4: only send with new flag, to maintain legacy behavior - on ipv6: send at most a single pktinfo cmsg - on ipv6: initialize fields if not yet initialized The recv cmsg interfaces are also relevant to the discussion of whether looping packet headers is problematic. For v6, cmsgs that identify many headers are already returned. This patch expands that to v4. If it sounds reasonable, I will follow with patches 1. request timestamps without payload with SOF_TIMESTAMPING_OPT_TSONLY (http://patchwork.ozlabs.org/patch/366967/) 2. sysctl to conditionally drop all timestamps that have payload or cmsg from users without CAP_NET_RAW.

This ensures that error state changes are handled the same way everywhere (where this function is used).

When the swdev device learns a new mac/vlan on a port, it sends some async notification to the driver and the driver installs an FDB in the device. To give a holistic system view, the learned mac/vlan should be reflected in the bridge's FBD table, so the user, using normal iproute2 cmds, can view what is currently learned by the device. This API on the bridge driver gives a way for the swdev driver to install an FBD entry in the bridge FBD table. (And remove one). This is equivalent to the device running these cmds: bridge fdb [add|del] <mac> dev <dev> vid <vlan id> master This patch needs some extra eyeballs for review, in paricular around the locking and contexts.
