When netdev events happen, a rtnetlink_event() handler will send messages for every event in it's white list. These messages contain current information about a particular device, but they do not include the iformation about which event just happened. The consumer of the message has to try to infer this information. In some cases (ex: NETDEV_NOTIFY_PEERS), that is not possible. This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT that would have an encoding of the which event triggered this message. This would allow the the message consumer to easily determine if it is interested in a particular event or not. Signed-off-by: NVladislav Yasevich <vyasevic@redhat.com> Signed-off-by: NDavid S.

The rtnetlink_event currently functions as a blacklist where we block cerntain netdev events from being sent to user space. As a result, events have been added to the system that userspace probably doesn't care about. This patch converts the implementation to the white list so that newly events would have to be specifically added to the list to be sent to userspace. This would force new event implementers to consider whether a given event is usefull to user space or if it's just a kernel event.

Since commit d6580a9f ("kexec: sysrq: simplify sysrq-c handler"), the sysrq handler for the 'c' key has been sysrq_crash_op. Debugging code in the ibm_emac driver also tries to register a handler for the 'c' key, but this has no effect because register_sysrq_key() doesn't replace existing handlers. Since evidently no one has cared enough to fix this in the last 8 years, and it's very rare for drivers to register sysrq handlers (for good reason), just remove the dead code.

Earlier patch c4adfc82 ("bonding: make speed, duplex setting consistent with link state") made an attempt to keep slave state consistent with speed and duplex settings. Unfortunately link-state transition is used to change the active link especially when used in conjunction with mii-mon. The above mentioned patch broke that logic. Also when speed and duplex settings for a link are updated during a link-event, the link-status should not be changed to invoke correct transition logic. This patch fixes this issue by moving the link-state update outside of the bond_update_speed_duplex() fn and to the places where this fn is called and update link-state selectively.

cb_running is reported in /proc/self/net/netlink and it is reported by the ss tool, when it gets information from the proc files. sock_diag is a new interface which is used instead of proc files, so it looks reasonable that this interface has to report no less information about sockets than proc files. We use these flags to dump and restore netlink sockets. Signed-off-by: NAndrei Vagin <avagin@openvz.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Yuval Mintz says: ==================== qed: QM & ILT changes This series introduces several changes and improvements to existing queue manager and ILT configurations done during initialization. Notice some of the patches are actually future fixes, I.e., bugs that can't be triggered with exisiting driver but are needed for some future functionality. Patch #1 refactors the configuration of the hardware's queue manager, which is quite messy today. This contains most of the bulk [code-wise] in the series. Patch #2, #3 fix Timers related ILT configurations that are yet to affect qed in existing scenarios. Patch #4 reduces needless ILT lines wasted for RoCE configurations. Patch #5 allows RoCE partitions to manage with less memory regions [important, e.g., for Multi-function parititions with RoCE support]. ==================== Signed-off-by: NDavid S.

Add support for the net stats64 counters to the usbnet core. With that in place put the hooks into every usbnet driver to use it. This is a strait forward addition of 64bit counters for RX and TX packet and byte counts. It is done in the same style as for the other net drivers that support stats64. Note that the other stats fields remain as 32bit sized values (error counts, etc). The motivation to add this is that it is not particularly difficult to get the RX and TX byte counts to wrap on 32bit platforms.

When an incoming frame is tagged or when GRO is disabled, the skb handled to vxlan_xmit() doesn't contain a valid transport header offset. This makes ND proxying fail. We combine two changes: replace use of skb_transport_offset() and ensure the necessary amount of skb is linear just before using it: - In vxlan_xmit(), when determining if we have an ICMPv6 neighbor discovery packet, just check if it is an ICMPv6 packet and rely on neigh_reduce() to do more checks if this is the case. The use of pskb_may_pull() is replaced by skb_header_pointer() for just the IPv6 header. - In neigh_reduce(), add pskb_may_pull() for IPv6 header and neighbor discovery message since this was removed from vxlan_xmit(). Replace skb_transport_header() with ipv6_hdr() + 1. - In vxlan_na_create(), replace first skb_transport_offset() with ipv6_hdr() + 1 and second with skb_network_offset() + sizeof(struct ipv6hdr). Additionally, ensure we pskb_may_pull() the whole skb as we need it to iterate over the options. Signed-off-by: NVincent Bernat <vincent@bernat.im> Signed-off-by: NDavid S.
