When macvtap forwards skb to its tap, it needs to check if GSO needs to be performed. This is sometimes necessary when the HW device performed GRO, but the guest reading from the tap does not support it (ex: Windows 7).

Currently macvtap uses rcu_bh functions in its user facing fuction macvtap_get_user() and macvtap_put_user(). However, its packet handlers use normal rcu as the rcu_read_lock() is taken in netif_receive_skb(). We can safely discontinue the usage or rcu with bh disabled.

Macvtap uses a private lock to protect the relationship between macvtap_queue and macvlan_dev. The private lock is not needed since the relationship is managed by user via open(), release(), and dellink() calls. dellink() already happens under rtnl, so we can safely convert open() and release(), and use it in ioctl() as well.

Signed-off-by: NEric Dumazet <edumazet@google.com> mlx4 exclusively uses order-2 allocations in RX path, which are likely to fail under memory pressure. We therefore drop frames more than needed. This patch tries order-3, order-2, order-1 and finally order-0 allocations to keep good performance, yet allow allocations if/when memory gets fragmented. By using larger pages, and avoiding unnecessary get_page()/put_page() on compound pages, this patch improves performance as well, lowering false sharing on struct page. Also use GFP_KERNEL allocations in initialization path, as allocating 12 MB (390 order-3 pages) can easily fail with GFP_ATOMIC.

blkt settings (or LAN idle settings) for an OSA Express card determine when and how often an OSA Express card tells the operating system about new incoming packets. The semantic of these settings has changed starting with OSA Express3. Currently the qeth standard settings apply to OSA Express2 and older generations of OSA Express cards, while new generations of OSA Express cards require extra coding of their reasonable default. To cover future OSA Express generations the qeth default standard blkt setting is now the desired setting for OSA generations starting with OSA Express3, while the fixed set of older OSA Express cards receives its blkt settings explicitly.

Currently, there is no good possibility to debug netlink traffic that is being exchanged between kernel and user space. Therefore, this patch implements a netlink virtual device, so that netlink messages will be made visible to PF_PACKET sockets. Once there was an approach with a similar idea [1], but it got forgotten somehow. I think it makes most sense to accept the "overhead" of an extra netlink net device over implementing the same functionality from PF_PACKET sockets once again into netlink sockets. We have BPF filters that can already be easily applied which even have netlink extensions, we have RX_RING zero-copy between kernel- and user space that can be reused, and much more features. So instead of re-implementing all of this, we simply pass the skb to a given PF_PACKET socket for further analysis. Another nice benefit that comes from that is that no code needs to be changed in user space packet analyzers (maybe adding a dissector, but not more), thus out of the box, we can already capture pcap files of netlink traffic to debug/troubleshoot netlink problems. Also thanks goes to Thomas Graf, Flavio Leitner, Jesper Dangaard Brouer.

The lifetime of an irq_cpu_rmap is odd: we have to allocate it before installing IRQ handlers and free it before removing the IRQ handlers. As a result of this asymmetry, it was omitted from some failure paths. On another failure path, we could try to remove IRQ handlers we had not yet installed. Move the irq_cpu_rmap allocation and freeing alongside IRQ handler installation and removal, in efx_nic_{init,fini}_interrupts(). Count the number of IRQ handlers successfully installed and only remove those on the failure path. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

GRO can handle non-TCP packets and pass them up without coalescing, but it has to do some extra work to parse the packet which we can bypass using the hardware parse result. (This condition yields a false negative for TCP/IPv6 packets received by Falcon, but its performance is already poor in that case due to lack of checksum offload.)

Callers of skb_seq_read() are currently forced to call skb_abort_seq_read() even when consuming all the data because the last call to skb_seq_read (the one that returns 0 to indicate the end) fails to unmap the last fragment page. With this patch callers will be allowed to traverse the SKB data by calling skb_prepare_seq_read() once and repeatedly calling skb_seq_read() as originally intended (and documented in the original commit 677e90ed), that is, only call skb_abort_seq_read() if the sequential read is actually aborted.
