====================
netfilter/IPVS updates for net-next
The following patchset contains Netfilter updates for your net-next tree,
they are:
* Add full port randomization support. Some crazy researchers found a way
to reconstruct the secure ephemeral ports that are allocated in random mode
by sending off-path bursts of UDP packets to overrun the socket buffer of
the DNS resolver to trigger retransmissions, then if the timing for the
DNS resolution done by a client is larger than usual, then they conclude
that the port that received the burst of UDP packets is the one that was
opened. It seems a bit aggressive method to me but it seems to work for
them. As a result, Daniel Borkmann and Hannes Frederic Sowa came up with a
new NAT mode to fully randomize ports using prandom.
* Add a new classifier to x_tables based on the socket net_cls set via
cgroups. These includes two patches to prepare the field as requested by
Zefan Li. Also from Daniel Borkmann.
* Use prandom instead of get_random_bytes in several locations of the
netfilter code, from Florian Westphal.
* Allow to use the CTA_MARK_MASK in ctnetlink when mangling the conntrack
mark, also from Florian Westphal.
* Fix compilation warning due to unused variable in IPVS, from Geert
Uytterhoeven.
* Add support for UID/GID via nfnetlink_queue, from Valentina Giusti.
* Add IPComp extension to x_tables, from Fan Du.

+
+1. IPcomp: Small IP packet won't get compressed at sender, and failed on
+ policy check on receiver.
+
+Quote from RFC3173:
+2.2. Non-Expansion Policy
+
+ If the total size of a compressed payload and the IPComp header, as
+ defined in section 3, is not smaller than the size of the original
+ payload, the IP datagram MUST be sent in the original non-compressed
+ form. To clarify: If an IP datagram is sent non-compressed, no
+
+ IPComp header is added to the datagram. This policy ensures saving
+ the decompression processing cycles and avoiding incurring IP
+ datagram fragmentation when the expanded datagram is larger than the
+ MTU.
+
+ Small IP datagrams are likely to expand as a result of compression.
+ Therefore, a numeric threshold should be applied before compression,
+ where IP datagrams of size smaller than the threshold are sent in the
+ original form without attempting compression. The numeric threshold
+ is implementation dependent.
+
+Current IPComp implementation is indeed by the book, while as in practice
+when sending non-compressed packet to the peer(whether or not packet len
+is smaller than the threshold or the compressed len is large than original
+packet len), the packet is dropped when checking the policy as this packet
+matches the selector but not coming from any XFRM layer, i.e., with no
+security path. Such naked packet will not eventually make it to upper layer.
+The result is much more wired to the user when ping peer with different
+payload length.
+
+One workaround is try to set "level use" for each policy if user observed
+above scenario. The consequence of doing so is small packet(uncompressed)
+will skip policy checking on receiver side.

+/* Description:
+ * This header file describes the VF-PF communication protocol used
+ * by the various i40e drivers.
+ *
+ * Admin queue buffer usage:
+ * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
+ * flags, retval, datalen, and data addr are all used normally.
+ * Firmware copies the cookie fields when sending messages between the PF and
+ * VF, but uses all other fields internally. Due to this limitation, we
+ * must send all messages as "indirect", i.e. using an external buffer.
+ *
+ * All the vsi indexes are relative to the VF. Each VF can have maximum of
+ * three VSIs. All the queue indexes are relative to the VSI. Each VF can
+ * have a maximum of sixteen queues for all of its VSIs.
+ *
+ * The PF is required to return a status code in v_retval for all messages
+ * except RESET_VF, which does not require any response. The return value is of
+ * i40e_status_code type, defined in the i40e_type.h.
+ *
+ * In general, VF driver initialization should roughly follow the order of these
+ * opcodes. The VF driver must first validate the API version of the PF driver,
+ * then request a reset, then get resources, then configure queues and
+ * interrupts. After these operations are complete, the VF driver may start
+ * its queues, optionally add MAC and VLAN filters, and process traffic.

---help---
This is a standard Linux network device driver for the
on-chip Tilera Gigabit Ethernet and XAUI interfaces.
To compile this driver as a module, choose M here: the module
will be called tile_net.
-
-config PTP_1588_CLOCK_TILEGX
- tristate "Tilera TILE-Gx mPIPE as PTP clock"
- select PTP_1588_CLOCK
- depends on TILE_NET
- depends on TILEGX
- ---help---
- This driver adds support for using the mPIPE as a PTP
- clock. This clock is only useful if your PTP programs are
- getting hardware time stamps on the PTP Ethernet packets
- using the SO_TIMESTAMPING API.

+ * undefined in this case though. It is a bad option, but, unfortunately,
+ * nowadays most vendors do this. Apparently with the secret goal to sell
+ * you new devices, when you will add new protocol to your host, f.e. IPv6 8)
+ *
+ * CHECKSUM_COMPLETE:
+ *
+ * This is the most generic way. The device supplied checksum of the _whole_
+ * packet as seen by netif_rx() and fills out in skb->csum. Meaning, the
+ * hardware doesn't need to parse L3/L4 headers to implement this.
+ *
+ * Note: Even if device supports only some protocols, but is able to produce
+ * skb->csum, it MUST use CHECKSUM_COMPLETE, not CHECKSUM_UNNECESSARY.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ * This is identical to the case for output below. This may occur on a packet
+ * received directly from another Linux OS, e.g., a virtualized Linux kernel
+ * on the same host. The packet can be treated in the same way as
+ * CHECKSUM_UNNECESSARY, except that on output (i.e., forwarding) the
+ * checksum must be filled in by the OS or the hardware.
+ *
+ * B. Checksumming on output.
+ *
+ * CHECKSUM_NONE:
+ *
+ * The skb was already checksummed by the protocol, or a checksum is not
+ * required.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ * The device is required to checksum the packet as seen by hard_start_xmit()
+ * from skb->csum_start up to the end, and to record/write the checksum at
+ * offset skb->csum_start + skb->csum_offset.
+ *
+ * The device must show its capabilities in dev->features, set up at device
+ * setup time, e.g. netdev_features.h:
+ *
+ * NETIF_F_HW_CSUM - It's a clever device, it's able to checksum everything.
+ * NETIF_F_IP_CSUM - Device is dumb, it's able to checksum only TCP/UDP over
+ * IPv4. Sigh. Vendors like this way for an unknown reason.
+ * Though, see comment above about CHECKSUM_UNNECESSARY. 8)
+ * NETIF_F_IPV6_CSUM - About as dumb as the last one but does IPv6 instead.
+ * NETIF_F_... - Well, you get the picture.
+ *
+ * CHECKSUM_UNNECESSARY:
+ *
+ * Normally, the device will do per protocol specific checksumming. Protocol
+ * implementations that do not want the NIC to perform the checksum
+ * calculation should use this flag in their outgoing skbs.

+/* Heavy-Hitter Filter (HHF)
+ *
+ * Principles :
+ * Flows are classified into two buckets: non-heavy-hitter and heavy-hitter
+ * buckets. Initially, a new flow starts as non-heavy-hitter. Once classified
+ * as heavy-hitter, it is immediately switched to the heavy-hitter bucket.
+ * The buckets are dequeued by a Weighted Deficit Round Robin (WDRR) scheduler,
+ * in which the heavy-hitter bucket is served with less weight.
+ * In other words, non-heavy-hitters (e.g., short bursts of critical traffic)
+ * are isolated from heavy-hitters (e.g., persistent bulk traffic) and also have
+ * higher share of bandwidth.
+ *
+ * To capture heavy-hitters, we use the "multi-stage filter" algorithm in the
+ * following paper:
+ * [EV02] C. Estan and G. Varghese, "New Directions in Traffic Measurement and
+ * Accounting", in ACM SIGCOMM, 2002.
+ *
+ * Conceptually, a multi-stage filter comprises k independent hash functions
+ * and k counter arrays. Packets are indexed into k counter arrays by k hash
+ * functions, respectively. The counters are then increased by the packet sizes.
+ * Therefore,
+ * - For a heavy-hitter flow: *all* of its k array counters must be large.
+ * - For a non-heavy-hitter flow: some of its k array counters can be large
+ * due to hash collision with other small flows; however, with high
+ * probability, not *all* k counters are large.
+ *
+ * By the design of the multi-stage filter algorithm, the false negative rate
+ * (heavy-hitters getting away uncaptured) is zero. However, the algorithm is
+ * susceptible to false positives (non-heavy-hitters mistakenly classified as
+ * heavy-hitters).
+ * Therefore, we also implement the following optimizations to reduce false
+ * positives by avoiding unnecessary increment of the counter values:
+ * - Optimization O1: once a heavy-hitter is identified, its bytes are not
+ * accounted in the array counters. This technique is called "shielding"
+ * in Section 3.3.1 of [EV02].
+ * - Optimization O2: conservative update of counters
+ * (Section 3.3.2 of [EV02]),
+ * New counter value = max {old counter value,
+ * smallest counter value + packet bytes}
+ *
+ * Finally, we refresh the counters periodically since otherwise the counter
+ * values will keep accumulating.
+ *
+ * Once a flow is classified as heavy-hitter, we also save its per-flow state
+ * in an exact-matching flow table so that its subsequent packets can be
+ * dispatched to the heavy-hitter bucket accordingly.
+ *
+ *
+ * At a high level, this qdisc works as follows:
+ * Given a packet p:
+ * - If the flow-id of p (e.g., TCP 5-tuple) is already in the exact-matching
+ * heavy-hitter flow table, denoted table T, then send p to the heavy-hitter
+ * bucket.
+ * - Otherwise, forward p to the multi-stage filter, denoted filter F
+ * + If F decides that p belongs to a non-heavy-hitter flow, then send p
+ * to the non-heavy-hitter bucket.
+ * + Otherwise, if F decides that p belongs to a new heavy-hitter flow,
+ * then set up a new flow entry for the flow-id of p in the table T and
+ * send p to the heavy-hitter bucket.
+ *
+ * In this implementation:
+ * - T is a fixed-size hash-table with 1024 entries. Hash collision is
+ * resolved by linked-list chaining.
+ * - F has four counter arrays, each array containing 1024 32-bit counters.
+ * That means 4 * 1024 * 32 bits = 16KB of memory.
+ * - Since each array in F contains 1024 counters, 10 bits are sufficient to
+ * index into each array.
+ * Hence, instead of having four hash functions, we chop the 32-bit
+ * skb-hash into three 10-bit chunks, and the remaining 10-bit chunk is
+ * computed as XOR sum of those three chunks.
+ * - We need to clear the counter arrays periodically; however, directly
+ * memsetting 16KB of memory can lead to cache eviction and unwanted delay.
+ * So by representing each counter by a valid bit, we only need to reset
+ * 4K of 1 bit (i.e. 512 bytes) instead of 16KB of memory.
+ * - The Deficit Round Robin engine is taken from fq_codel implementation
+ * (net/sched/sch_fq_codel.c). Note that wdrr_bucket corresponds to
+ * fq_codel_flow in fq_codel implementation.
