In setups with a global scope address on an interface, and a lesser scope address on an interface sending IGMP reports, the reports can be sent using the other interfaces global scope address rather than the local interface address. RFC 2236 suggests: Ignore the Report if you cannot identify the source address of the packet as belonging to a subnet assigned to the interface on which the packet was received. since such reports could be forged. Look at the protocol when deciding if a RT_SCOPE_LINK address should be used for the packet. Signed-off-by: NAndrew Lunn <andrew@lunn.ch> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

tcp_sacktag_one() always picks the earliest sequence SACKed for RTT. This might not make sense for congestion control in cases where: 1. ACKs are lost, i.e. a SACK following a lost SACK covers both new and old segments at the receiver. 2. The receiver disregards the RFC 5681 recommendation to immediately ACK out-of-order segments. Give congestion control a RTT for the latest segment SACKed, which is the most accurate RTT estimate, but preserve the conservative RTT for RTO.

Alexander Duyck says: ==================== A few minor clean-ups to eth_type_trans This series addresses a few minor issues I found in eth_type_trans that that allow us to gain back something like 3 or more cycles per packet. The first change is to drop the byte swap since it isn't necessary. On x86 we could just check the first byte and compare that against the upper 8 bits of the Ethertype to determine if we are dealing with a size value or not. The second makes it so that the value we read in to test for multicast can be used for the address comparison. This allows us to avoid a second read of the destination address. The final change is to avoid some unneeded instructions in computing the Ethernet header pointer. When we start the call the Ethernet header is at skb->data, so we just use that rather than computing mac_header, and then adding that back to skb->head. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Alexander Duyck 提交于
Avoid recomputing the Ethernet header location and instead just use the pointer provided by skb->data. The problem with using eth_hdr is that the compiler wasn't smart enough to realize that skb->head + skb->mac_header was the same thing as skb->data before it added ETH_HLEN. By just caching it off before calling skb_pull_inline we can avoid a few unnecessary instructions. Signed-off-by: NAlexander Duyck <alexander.h.duyck@redhat.com> Signed-off-by: NDavid S.

This change makes it so that we process the address in is_multicast_ether_addr at the same size as the other calls. This allows us to avoid duplicate reads when used with other calls such as is_zero_ether_addr or eth_addr_copy. In addition I have added a 64 bit version of the function so in eth_type_trans we can process the destination address as a 64 bit value throughout.

This change takes advantage of the fact that ETH_P_802_3_MIN is aligned to 512 so as a result we can actually ignore the lower 8b when comparing the Ethertype to ETH_P_802_3_MIN.

This patch divides the IPv6 flow label space into two ranges: 0-7ffff is reserved for flow label manager, 80000-fffff will be used for creating auto flow labels (per RFC6438). This only affects how labels are set on transmit, it does not affect receive. This range split can be disbaled by systcl. Background: IPv6 flow labels have been an unmitigated disappointment thus far in the lifetime of IPv6. Support in HW devices to use them for ECMP is lacking, and OSes don't turn them on by default. If we had these we could get much better hashing in IPv6 networks without resorting to DPI, possibly eliminating some of the motivations to to define new encaps in UDP just for getting ECMP. Unfortunately, the initial specfications of IPv6 did not clarify how they are to be used. There has always been a vague concept that these can be used for ECMP, flow hashing, etc. and we do now have a good standard how to this in RFC6438. The problem is that flow labels can be either stateful or stateless (as in RFC6438), and we are presented with the possibility that a stateless label may collide with a stateful one. Attempts to split the flow label space were rejected in IETF. When we added support in Linux for RFC6438, we could not turn on flow labels by default due to this conflict. This patch splits the flow label space and should give us a path to enabling auto flow labels by default for all IPv6 packets. This is an API change so we need to consider compatibility with existing deployment. The stateful range is chosen to be the lower values in hopes that most uses would have chosen small numbers. Once we resolve the stateless/stateful issue, we can proceed to look at enabling RFC6438 flow labels by default (starting with scaled testing).

It is currently targeted for net-next due to the number of code churn but it is also applicable to net (should be without conflict).

Patch 03 fixes the /128 route disappearing bug.

inet_peer is indexed by the dst address alone. However, the fib6 tree could have multiple routing entries (rt6_info) for the same dst. For example, 1. A /128 dst via multiple gateways. 2. A RTF_CACHE route cloned from a /128 route. In the above cases, all of them will share the same metrics and step on each other. This patch will steer away from inet_peer's metrics and use dst_cow_metrics_generic() for everything. Change Highlights: 1. Remove rt6_cow_metrics() which currently acquires metrics from inet_peer for DST_HOST route (i.e. /128 route). 2. Add rt6i_pmtu to take care of the pmtu update to avoid creating a full size metrics just to override the RTAX_MTU. 3. After (2), the RTF_CACHE route can also share the metrics with its dst.from route, by: dst_init_metrics(&cache_rt->dst, dst_metrics_ptr(cache_rt->dst.from), true); 4. Stop creating RTF_CACHE route by cloning another RTF_CACHE route. Instead, directly clone from rt->dst. [ Currently, cloning from another RTF_CACHE is only possible during rt6_do_redirect(). Also, the old clone is removed from the tree immediately after the new clone is added. ] In case of cloning from an older redirect RTF_CACHE, it should work as before. In case of cloning from an older pmtu RTF_CACHE, this patch will forget the pmtu and re-learn it (if there is any) from the redirected route. The _rt6i_peer and DST_METRICS_FORCE_OVERWRITE will be removed in the next cleanup patch.

However if one of these routes is marked as invalid, we may fail to find a route even if there is a appropriate route with lower priority.

It is a prep work for the later bug-fix patch which will stop /128 route from disappearing after pmtu update. The later bug-fix patch will allow a /128 route and its RTF_CACHE clone both exist at the same fib6_node. To do this, we need to prepare the existing fib6 tree search to expect RTF_CACHE for /128 route. Note that the fn->leaf is sorted by rt6i_metric. Hence, RTF_CACHE (if there is any) is always at the front. This property leads to the following: 1. When doing ip6_route_del(), it should honor the RTF_CACHE flag which the caller is used to ask for deleting clone or non-clone. The rtm_to_fib6_config() should also check the RTM_F_CLONED and then set RTF_CACHE accordingly so that: - 'ip -6 r del...' will make ip6_route_del() to delete a route and all its clones. Note that its clones is flushed by fib6_del() - 'ip -6 r flush table cache' will make ip6_route_del() to only delete clone(s). 2. Exclude RTF_CACHE from addrconf_get_prefix_route() which should not configure on a cloned route. 3. No change is need for rt6_device_match() since it currently could return a RTF_CACHE clone route, so the later bug-fix patch will not affect it.
