由 Hannes Frederic Sowa 提交于
We currently don't report IPV6_RECVPKTINFO in cmsg access ancillary data for IPv4 datagrams on IPv6 sockets. This patch splits the ip6_datagram_recv_ctl into two functions, one which handles both protocol families, AF_INET and AF_INET6, while the ip6_datagram_recv_specific_ctl only handles IPv6 cmsg data. ip6_datagram_recv_*_ctl never reported back any errors, so we can make them return void. Also provide a helper for protocols which don't offer dual personality to further use ip6_datagram_recv_ctl, which is exported to modules. I needed to shuffle the code for ping around a bit to make it easier to implement dual personality for ping ipv6 sockets in future.

This information is already available via IPV6_FLOWINFO of IPV6_2292PKTOPTIONS, and them a filtering to get the flow label information.

由 Michal Sekletar 提交于
For user space packet capturing libraries such as libpcap, there's currently only one way to check which BPF extensions are supported by the kernel, that is, commit aa1113d9 ("net: filter: return -EINVAL if BPF_S_ANC* operation is not supported"). For querying all extensions at once this might be rather inconvenient. Therefore, this patch introduces a new option which can be used as an argument for getsockopt(), and allows one to obtain information about which BPF extensions are supported by the current kernel. As David Miller suggests, we do not need to define any bits right now and status quo can just return 0 in order to state that this versions supports SKF_AD_PROTOCOL up to SKF_AD_PAY_OFFSET. Later additions to BPF extensions need to add their bits to the bpf_tell_extensions() function, as documented in the comment.

Pull networking fixes from David Miller: 1) The value choosen for the new SO_MAX_PACING_RATE socket option on parisc was very poorly choosen, let's fix it while we still can. From Eric Dumazet. 2) Our generic reciprocal divide was found to handle some edge cases incorrectly, part of this is encoded into the BPF as deep as the JIT engines themselves. Just use a real divide throughout for now. From Eric Dumazet. 3) Because the initial lookup is lockless, the TCP metrics engine can end up creating two entries for the same lookup key. Fix this by doing a second lookup under the lock before we actually create the new entry. From Christoph Paasch. 4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork. 5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting. From Dan Carpenter. 6) Netlink socket dumping uses the wrong socket state for timewait sockets. Fix from Neal Cardwell. 7) Fix netlink memory leak in ieee802154_add_iface(), from Christian Engelmayer. 8) Multicast forwarding in ipv4 can overflow the per-rule reference counts, causing all multicast traffic to cease.

He cleans up the code by removing the adapter structure as a parameter from multiple functions in favor of using the ixgbevf_ring structure and moves hot-path specific statistic int the ring structure for anticipated performance gains. He also removes the Tx/Rx counters for checksum offload and adds counters for tx_restart_queue and tx_timeout_count. Next he makes it so that the first tx_buffer structure acts as a central storage location for most the skb info we are about to transmit, then takes advantage of the dma buffer always being present in the first descriptor and mapped as single allowing a call to dma_unmap_single which alleviates the need to check for DMA mapping in ixgbevf_clean_tx_irq().

This patch adds capability to configure DCB on i40e network interfaces using Intel XL710 adapter firmware APIs. By default all VSIs are only enabled for the default traffic class enabled by firmware for any given PF. The driver would query the firmware for the traffic classes that are enabled for the port and reconfigure the LAN VSI to match to the port traffic class settings. All other VSIs are only enabled for the default traffic class settings for now. The driver registers and listens to firmware events that may require change in the DCB settings. It may reconfigure the VSI settings based on these events. This patch exposes IEEE DCBNL interfaces for the i40e driver to allow any application to query the DCB settings on the adapter.

The firmware runs DCBX in willing mode and configures the port as per the DCB settings recommended by it's link partner. By default in absence of any DCBX; firmware would configure the port with a single traffic class and all of the port bandwith will be allocated to that traffic class.

The s390 bpf jit compiler emits the signed divide instructions "dr" and "d" for unsigned divisions. This can cause problems: the dividend will be zero extended to a 64 bit value and the divisor is the 32 bit signed value as specified A or X accumulator, even though A and X are supposed to be treated as unsigned values. The divide instrunctions will generate an exception if the result cannot be expressed with a 32 bit signed value. This is the case if e.g. the dividend is 0xffffffff and the divisor either 1 or also 0xffffffff (signed: -1). To avoid all these issues simply use unsigned divide instructions.

Scott Feldman says: ==================== bonding: add slave netlink and sysfs support v2: - Address review comment from Ding (and Veacesiav): handle kobj cleanup if sysfs_create_file() fails when adding slave attribute nodes. v1: The following series adds bonding slave netlink and sysfs interfaces. Slave interfaces get a new IFLA_SLAVE set of netlink attributes, along with RTM_NEWLINK notification when slave's active status changes. The sysfs interface adds read-only nodes for slave attributes under a /slave dir, simliar to how bond interfaces get a /bonding dir for bonding attributes. ==================== Reviewed-by: NDing Tianhong <dingtianhong@huawei.com> Signed-off-by: NDavid S.

If link is IFF_SLAVE, extend link dev netlink attributes to include slave attributes with new IFLA_SLAVE nest. Add netlink notification (RTM_NEWLINK) when slave status changes from backup to active, or visa-versa. Adds new ndo_get_slave op to net_device_ops to fill skb with IFLA_SLAVE attributes. Currently only used by bonding driver, but could be used by other aggregating devices with slaves. Signed-off-by: NScott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: NDavid S.

Add sub-directory under /sys/class/net/<interface>/slave with read-only attributes for slave. Directory only appears when <interface> is a slave. $ tree /sys/class/net/eth2/slave/ /sys/class/net/eth2/slave/ ├── ad_aggregator_id ├── link_failure_count ├── mii_status ├── perm_hwaddr ├── queue_id └── state $ cat /sys/class/net/eth2/slave/* 2 0 up 40:02:10:ef:06:01 0 active Signed-off-by: NScott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: NDavid S.
