Add ip_cmsg_recv_offset function which takes an offset argument that indicates the starting offset in skb where data is being received from. This will be useful in the case of UDP and provided checksum to user space. ip_cmsg_recv is an inline call to ip_cmsg_recv_offset with offset of zero.

Move the IP_CMSG_* constants from ip_sockglue.c to inet_sock.h so that they can be referenced in other source files. Restructure ip_cmsg_recv to not go through flags using shift, check for flags by 'and'. This eliminates both the shift and a conditional per flag check.

Move convert_csum from udp_sock to inet_sock. This allows the possibility that we can use convert checksum for different types of sockets and also allows convert checksum to be enabled from inet layer (what we'll want to do when enabling IP_CHECKSUM cmsg).

This patch uses skb->xmit_more flag to batch TX requests. TX is flushed either when xmit_more is false or there is no more space in the TXQ. Skyhawk-R and BEx chips require an even number of wrbs to be posted. So, when a batch of TX requests is accumulated, the last header wrb may need to be fixed with an extra dummy wrb. This patch refactors be_xmit() routine as a sequence of be_xmit_enqueue() and be_xmit_flush() calls. The Tx completion code is also updated to be able to unmap/free a batch of skbs rather than a single skb. Signed-off-by: NSathya Perla <sathya.perla@emulex.com> Signed-off-by: NDavid S.

Jesse Gross says: ==================== Geneve Cleanups Much of the basis for the Geneve code comes from VXLAN. However, Geneve is quite a bit simpler than VXLAN and so this cleans up a lot of the infrastruction - particularly around locking - where the extra complexity is not necessary. ==================== Signed-off-by: NDavid S.

When searching for an existing socket to reuse, the address family is not taken into account - only port number. This means that an IPv4 socket could be used for IPv6 traffic and vice versa, which is sure to cause problems when passing packets. It is not possible to trigger this problem currently because the only user of Geneve creates just IPv4 sockets. However, that is likely to change in the near future.

The hash table for open Geneve ports is used only on creation and deletion time. It is not performance critical and is not likely to grow to a large number of items.

The existing Geneve locking scheme was pulled over directly from VXLAN. However, VXLAN has a number of built in mechanisms which make the locking more complex and are unlikely to be necessary with Geneve. This simplifies the locking to use a basic scheme of a mutex when doing updates plus RCU on receive. In addition to making the code easier to read, this also avoids the possibility of a race when creating or destroying sockets since UDP sockets and the list of Geneve sockets are protected by different locks. After this change, the entire operation is atomic. Signed-off-by: NJesse Gross <jesse@nicira.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The work queue is used only to free the UDP socket upon destruction. This is not necessary with Geneve and generally makes the code more difficult to reason about. It also introduces nondeterministic behavior such as when a socket is rapidly deleted and recreated, which could fail as the the deletion happens asynchronously.

Thomas Graf says: ==================== rhashtable: Per bucket locks & deferred table resizing Prepares for and introduces per bucket spinlocks and deferred table resizing. This allows for parallel table mutations in different hash buckets from atomic context. The resizing occurs in the background in a separate worker thread while lookups, inserts, and removals can continue. Also modified the chain linked list to be terminated with a special nulls marker to allow entries to move between multiple lists. Last but not least, reintroduces lockless netlink_lookup() with deferred Netlink socket destruction to avoid the side effect of increased netlink_release() runtime. ==================== Signed-off-by: NDavid S.

In order to allow for wider usage of rhashtable, use a special nulls marker to terminate each chain. The reason for not using the existing nulls_list is that the prev pointer usage would not be valid as entries can be linked in two different buckets at the same time. The 4 nulls base bits can be set through the rhashtable_params structure like this: struct rhashtable_params params = { [...] .nulls_base = (1U << RHT_BASE_SHIFT), }; This reduces the hash length from 32 bits to 27 bits.

Introduces an array of spinlocks to protect bucket mutations. The number of spinlocks per CPU is configurable and selected based on the hash of the bucket. This allows for parallel insertions and removals of entries which do not share a lock. The patch also defers expansion and shrinking to a worker queue which allows insertion and removal from atomic context. Insertions and deletions may occur in parallel to it and are only held up briefly while the particular bucket is linked or unzipped. Mutations of the bucket table pointer is protected by a new mutex, read access is RCU protected. In the event of an expansion or shrinking, the new bucket table allocated is exposed as a so called future table as soon as the resize process starts. Lookups, deletions, and insertions will briefly use both tables. The future table becomes the main table after an RCU grace period and initial linking of the old to the new table was performed. Optimization of the chains to make use of the new number of buckets follows only the new table is in use. The side effect of this is that during that RCU grace period, a bucket traversal using any rht_for_each() variant on the main table will not see any insertions performed during the RCU grace period which would at that point land in the future table. The lookup will see them as it searches both tables if needed. Having multiple insertions and removals occur in parallel requires nelems to become an atomic counter.

The removal function of nft_hash currently stores a reference to the previous element during lookup which is used to optimize removal later on. This was possible because a lock is held throughout calling rhashtable_lookup() and rhashtable_remove(). With the introdution of deferred table resizing in parallel to lookups and insertions, the nftables lock will no longer synchronize all table mutations and the stored pprev may become invalid. Removing this optimization makes removal slightly more expensive on average but allows taking the resize cost out of the insert and remove path.

Subsequent patches will require access to the bucket tail. Access to the tail is relatively cheap as the automatic resizing of the table should keep the number of entries per bucket to no more than 0.75 on average.

This patch is in preparation to introduce per bucket spinlocks. It extends all iterator macros to take the bucket table and bucket index. It also introduces a new rht_dereference_bucket() to handle protected accesses to buckets. It introduces a barrier() to the RCU iterators to the prevent the compiler from caching the first element. The lockdep verifier is introduced as stub which always succeeds and properly implement in the next patch when the locks are introduced.
