2018-05-06netfilter: nft_numgen: add map lookups for numgen statementsLaura Garcia Liebana2-5/+84
This patch includes a new attribute in the numgen structure to allow the lookup of an element based on the number generator as a key. For this purpose, different ops have been included to extend the current numgen inc functions. Currently, only supported for numgen incremental operations, but it will be supported for random in a follow-up patch.

Basically it provides consistent hashing but offers some special features about disruption and load balancing. 1) minimal disruption: when the set of destinations changes, a connection will likely be sent to the same destination as it was before. 2) load balancing: each destination will receive an almost equal number of connections. Seel also: [3.4 Consistent Hasing] in https://www.usenix.org/system/files/conference/nsdi16/nsdi16-paper-eisenbud.pdf " * Fix to correct implementation of Knuth's multiplicative hashing which is used in sh/dh/lblc/lblcr algorithms.

Marco De Benedetto says: I would like to use a timeout of 30 days for elements in a set but it seems there is a some kind of problem above 24d20h31m23s. Fix this by using 'jiffies64' for timeout handling to get same behaviour on 32 and 64bit systems. nftables passes timeouts as u64 in milliseconds to the kernel, but on kernel side we used a mixture of 'long' and jiffies conversions rather than u64 and jiffies64.

2018-04-24netfilter: add NAT support for shifted portmap rangesThierry Du Tre36-71/+145
This is a patch proposal to support shifted ranges in portmaps. (i.e. tcp/udp incoming port 5000-5100 on WAN redirected to LAN 192.168.1.5:2000-2100) Currently DNAT only works for single port or identical port ranges. (i.e. ports 5000-5100 on WAN interface redirected to a LAN host while original destination port is not altered) When different port ranges are configured, either 'random' mode should be used, or else all incoming connections are mapped onto the first port in the redirect range. (in described example WAN:5000-5100 will all be mapped to 192.168.1.5:2000) This patch introduces a new mode indicated by flag NF_NAT_RANGE_PROTO_OFFSET which uses a base port value to calculate an offset with the destination port present in the incoming stream. That offset is then applied as index within the redirect port range (index modulo rangewidth to handle range overflow). In described example the base port would be 5000. An incoming stream with destination port 5004 would result in an offset value 4 which means that the NAT'ed stream will be using destination port 2004. Other possibilities include deterministic mapping of larger or multiple ranges to a smaller range : WAN:5000-5999 -> LAN:5000-5099 (maps WAN port 5*xx to port 51xx) This patch does not change any current behavior. It just adds new NAT proto range functionality which must be selected via the specific flag when intended to use. A patch for iptables (libipt_DNAT.c + libip6t_DNAT.c) will also be proposed which makes this functionality immediately available.

2018-04-24netfilter: nf_tables: Simplify set backend selectionPhil Sutter5-143/+139
Drop nft_set_type's ability to act as a container of multiple backend implementations it chooses from. Instead consolidate the whole selection logic in nft_select_set_ops() and the actual backend provided estimate() callback. This turns nf_tables_set_types into a list containing all available backends which is traversed when selecting one matching userspace requested criteria. Also, this change allows to embed nft_set_ops structure into nft_set_type and pull flags field into the latter as it's only used during selection phase. A crucial part of this change is to make sure the new layout respects hash backend constraints formerly enforced by nft_hash_select_ops() function: This is achieved by introduction of a specific estimate() callback for nft_hash_fast_ops which returns false for key lengths != 4. In turn, nft_hash_estimate() is changed to return false for key lengths == 4 so it won't be chosen by accident. Also, both callbacks must return false for unbounded sets as their size estimate depends on a known maximum element count. Note that this patch partially reverts commit 4f2921ca21b71 ("netfilter: nf_tables: meter: pick a set backend that supports updates") by making nft_set_ops_candidate() not explicitly look for an update callback but make NFT_SET_EVAL a regular backend feature flag which is checked along with the others. This way all feature requirements are checked in one go. Signed-off-by: Phil Sutter <[email protected]> Signed-off-by: Pablo Neira Ayuso <[email protected]>

2018-04-24netfilter: nf_flow_table: add support for sending flows back to the slow pathFelix Fietkau1-1/+49
Since conntrack hasn't seen any packets from the offloaded flow in a while, and the timeout for offloaded flows is set to an extremely long value, we need to fix up the state before we can send a flow back to the slow path. For TCP, reset td_maxwin in both directions, which makes it resync its state on the next packets. Use the regular timeout for TCP and UDP established connections.

2018-04-24netfilter: nf_flow_table: add a new flow state for tearing down offloadingFelix Fietkau2-8/+16
On cleanup, this will be treated differently from FLOW_OFFLOAD_DYING: If FLOW_OFFLOAD_DYING is set, the connection is going away, so both the offload state and the connection tracking entry will be deleted. If FLOW_OFFLOAD_TEARDOWN is set, the connection remains alive, but the offload state is torn down. This is useful for cases that require more complex state tracking / timeout handling on TCP, or if the connection has been idle for too long.

2018-04-18hv_netvsc: propogate Hyper-V friendly name into interface aliasStephen Hemminger2-0/+29
This patch implement the 'Device Naming' feature of the Hyper-V network device API. In Hyper-V on the host through the GUI or PowerShell it is possible to enable the device naming feature which causes the host to make available to the guest the name of the device. This shows up in the RNDIS protocol as the friendly name. The name has no particular meaning and is limited to 256 characters. The value can only be set via PowerShell on the host, but could be scripted for mass deployments. The default value is the string 'Network Adapter' and since that is the same for all devices and useless, the driver ignores it. In Windows, the value goes into a registry key for use in SNMP ifAlias. For Linux, this patch puts the value in the network device alias property; where it is visible in ip tools and SNMP. The host provided ifAlias is just a suggestion, and can be overridden by later ip commands. Also requires exporting dev_set_alias in netdev core.
