* net/smc: remove unused fields from smc structuresKarsten Graul2018-03-014-18/+8Star
| | | | | | | | | | | | The daddr field holds the destination IPv4 address. The field was set but never used and can be removed. The addr field was a left-over from an earlier version of non-blocking connects and can be removed. The result of the call to kernel_getpeername is not used, the call can be removed. Non-blocking connects are working, so remove restriction comment.

* ipmr, ip6mr: Unite dumproute flowsYuval Mintz2018-03-013-239/+201Star
| | | | | | | | | | | | | | | The various MFC entries are being held in the same kind of mr_tables for both ipmr and ip6mr, and their traversal logic is identical. Also, with the exception of the addresses [and other small tidbits] the major bulk of the nla setting is identical. Unite as much of the dumping as possible between the two. Notice this requires creating an mr_table iterator for each, as the for-each preprocessor macro can't be used by the common logic.

| | | | | | | | | | | | | | | ipmr and ip6mr utilize the exact same methods for searching the hashed resolved connections, difference being only in the construction of the hash comparison key. In order to unite the flow, introduce an mr_table operation set that would contain the protocol specific information required for common flows, in this case - the hash parameters and a comparison key representing a (*,*) route.

Make a common structure encapsulating most of the multicast routing logic - mr_mfc and convert both ipmr and ip6mr into using it.

| | | | | | | | | | | | | | | | The two implementations have almost identical structures - vif_device and mif_device. As a step toward uniforming the mr_tables, eliminate the mif_device and relocate the vif_device definition into a new common header file. Also, introduce a common initializing function for setting most of the vif_device fields in a new common source file. This requires modifying the ipv{4,6] Kconfig and ipv4 makefile as we're introducing a new common config option - CONFIG_IP_MROUTE_COMMON.

* rds: deliver zerocopy completion notification with dataSowmini Varadhan2018-02-274-25/+53
| | | | | | | | | | | | | | | | | | | | | | | This commit is an optimization over commit 01883eda72bd ("rds: support for zcopy completion notification") for PF_RDS sockets. RDS applications are predominantly request-response transactions, so it is more efficient to reduce the number of system calls and have zerocopy completion notification delivered as ancillary data on the POLLIN channel. Cookies are passed up as ancillary data (at level SOL_RDS) in a struct rds_zcopy_cookies when the returned value of recvmsg() is greater than, or equal to, 0. A max of RDS_MAX_ZCOOKIES may be passed with each message. This commit removes support for zerocopy completion notification on MSG_ERRQUEUE for PF_RDS sockets.

* | net: Convert simple pernet_operationsKirill Tkhai2018-02-273-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These pernet_operations make pretty simple actions like variable initialization on init, debug checks on exit, and so on, and they obviously are able to be executed in parallel with any others: vrf_net_ops lockd_net_ops grace_net_ops xfrm6_tunnel_net_ops kcm_net_ops tcf_net_ops Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S.

* | net: Convert synproxy_net_opsKirill Tkhai2018-02-271-0/+1
| | | | | | | | | | | | | | | | | | These pernet_operations create and destroy /proc entries and allocate extents to template ct, which depend on global nf_ct_ext_types[] array. So, we are able to mark them async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | net: Convert hashlimit_net_ops and recent_net_opsKirill Tkhai2018-02-272-0/+2
| | | | | | | | | | | | | | | | | | | | These pernet_operations just create and destroy /proc entries. Also, new /proc entries also may come after new nf rules are added, but this is not possible, when net isn't alive. So, they are safe to be marked as async.
