o Some adapter types do not support co-existence of Legacy Interrupt with MSI-x or MSI among multiple functions. For those adapters, prevent attaching to a function during normal load, if MSI-x or MSI vectors are not available. o Using module parameters use_msi=0 and use_msi_x=0, driver can be loaded in legacy mode for all functions in the adapter.

Pablo Neira Ayuso says: ==================== This batch contains netfilter updates for you net-next tree, they are: * The new connlabel extension for x_tables, that allows us to attach labels to each conntrack flow. The kernel implementation uses a bitmask and there's a file in user-space that maps the bits with the corresponding string for each existing label. By now, you can attach up to 128 overlapping labels. From Florian Westphal. * A new round of improvements for the netns support for conntrack. Gao feng has moved many of the initialization code of each module of the netns init path. He also made several code refactoring, that code looks cleaner to me now. * Added documentation for all possible tweaks for nf_conntrack via sysctl, from Jiri Pirko. * Cisco 7941/7945 IP phone support for our SIP conntrack helper, from Kevin Cernekee. * Missing header file in the snmp helper, from Stephen Hemminger. * Finally, a couple of fixes to resolve minor issues with these changes, from myself. ==================== Signed-off-by:

When posting a message on the bulletin board, the PF calculates crc over the message and places the result in the message. When the VF samples the Bulletin Board it copies the message aside and validates this crc. The length of the message is crucial here and must be the same in both parties. Since the PF is running in the Hypervisor and the VF is running in a Vm, they can possibly be of different versions. As the Bulletin Board is designed to grow forward in future versions, in the VF the length must not be the size of the message structure but instead it should be a field in the message itself.

In INTA mode, cnic and bnx2x share the same IRQ. During chip reset, for example, cnic will stop servicing IRQs after it has shutdown the cnic hardware resources. However, the shared IRQ is still active as bnx2x needs to finish the reset. There is a window when bnx2x does not know that cnic is no longer handling IRQ and things don't always work properly. Add a flag to tell bnx2x that cnic is handling IRQ. The flag is set before the first cnic IRQ is expected and cleared when no more cnic IRQs are expected, so there should be no race conditions.

Slightly changes the bnx2x code without `true' functional changes. Changes include: 1. Gathering macros into a single macro when combination is used multiple times. 2. Exporting parts of functions into their own functions. 3. Return values after if-else instead of only on the else condition (where current flow would simply return same value later in the code) 4. Removing some unnecessary code (either dead-code or incorrect conditions) Signed-off-by: -

Tom Herbert says: ==================== This series implements so_reuseport (SO_REUSEPORT socket option) for TCP and UDP. For TCP, so_reuseport allows multiple listener sockets to be bound to the same port. In the case of UDP, so_reuseport allows multiple sockets to bind to the same port. To prevent port hijacking all sockets bound to the same port using so_reuseport must have the same uid. Received packets are distributed to multiple sockets bound to the same port using a 4-tuple hash. The motivating case for so_resuseport in TCP would be something like a web server binding to port 80 running with multiple threads, where each thread might have it's own listener socket. This could be done as an alternative to other models: 1) have one listener thread which dispatches completed connections to workers. 2) accept on a single listener socket from multiple threads. In case #1 the listener thread can easily become the bottleneck with high connection turn-over rate. In case #2, the proportion of connections accepted per thread tends to be uneven under high connection load (assuming simple event loop: while (1) { accept(); process() }, wakeup does not promote fairness among the sockets. We have seen the disproportion to be as high as 3:1 ratio between thread accepting most connections and the one accepting the fewest. With so_reusport the distribution is uniform. The TCP implementation has a problem in that the request sockets for a listener are attached to a listener socket. If a SYN is received, a listener socket is chosen and request structure is created (SYN-RECV state). If the subsequent ack in 3WHS does not match the same port by so_reusport, the connection state is not found (reset) and the request structure is orphaned. This scenario would occur when the number of listener sockets bound to a port changes (new ones are added, or old ones closed). We are looking for a solution to this, maybe allow multiple sockets to share the same request table... The motivating case for so_reuseport in UDP would be something like a DNS server. An alternative would be to recv on the same socket from multiple threads. As in the case of TCP, the load across these threads tends to be disproportionate and we also see a lot of contection on the socket lock. Note that SO_REUSEADDR already allows multiple UDP sockets to bind to the same port, however there is no provision to prevent hijacking and nothing to distribute packets across all the sockets sharing the same bound port. This patch does not change the semantics of SO_REUSEADDR, but provides usable functionality of it for unicast. ==================== Signed-off-by: -

Move the code that register/unregister l4proto to the module_init/exit context. Given that we have to modify some interfaces to accomodate these changes, it is a good time to use shorter function names for this using the nf_ct_* prefix instead of nf_conntrack_*, that is: nf_ct_l4proto_register nf_ct_l4proto_pernet_register nf_ct_l4proto_unregister nf_ct_l4proto_pernet_unregister We same many line breaks with it.
