Change the algorithm. Read systimel twice and check for overflow. If there was no overflow, use the first value. If there was an overflow, read systimeh again and use the second systimel value. Signed-off-by:

This patch fixes wrong locking usage. In the context of slot reset, we should use lock. And during resume, there is no need of lock. Reported-by:

This patch implements the EEE in Sx code so that it only applies to parts that support EEE in Sx (as opposed to all parts that support EEE). It also uses the existing eee_advert and eee_lp_abiliity to set just the bits (100/1000) that should be set. Signed-off-by:

X722 fixes an issue from X710 where TX descriptor WB would not happen if the interrupts were disabled. In order for the write backs to happen a bit needs to be set in the dynamic interrupt control register called WB_ON_ITR. With this feature, the SW driver need not arm SW interrupts to work around the issue in X710. Signed-off-by:

X722 uses the admin queue to configure RSS. This patch adds the necessary flow changes to configure RSS through AQ. It also adds the separate VMDQ2 lookup tables and hash key programming for X722. X722 also exposes a different set of PCTYPES for RSS, this patch accommodates those changes. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next, they are: 1) A couple of cleanups for the netfilter core hook from Eric Biederman. 2) Net namespace hook registration, also from Eric. This adds a dependency with the rtnl_lock. This should be fine by now but we have to keep an eye on this because if we ever get the per-subsys nfnl_lock before rtnl we have may problems in the future. But we have room to remove this in the future by propagating the complexity to the clients, by registering hooks for the init netns functions. 3) Update nf_tables to use the new net namespace hook infrastructure, also from Eric. 4) Three patches to refine and to address problems from the new net namespace hook infrastructure. 5) Switch to alternate jumpstack in xtables iff the packet is reentering. This only applies to a very special case, the TEE target, but Eric Dumazet reports that this is slowing down things for everyone else. So let's only switch to the alternate jumpstack if the tee target is in used through a static key. This batch also comes with offline precalculation of the jumpstack based on the callchain depth. From Florian Westphal. 6) Minimal SCTP multihoming support for our conntrack helper, from Michal Kubecek. 7) Reduce nf_bridge_info per skbuff scratchpad area to 32 bytes, from Florian Westphal. 8) Fix several checkpatch errors in bridge netfilter, from Bernhard Thaler. 9) Get rid of useless debug message in ip6t_REJECT, from Subash Abhinov. ==================== Signed-off-by:David S.

Robert Shearman says: ==================== lwtunnel: encap locally-generated ipv4 packets Locally-generated IPv4 packets, such as from applications running on the host or traceroute/ping currently don't have lwtunnel output redirected encap applied. However, they should do in the same way as for forwarded packets and this patch series addresses that. ==================== Signed-off-by: -
Robert Shearman authored
lwtunnel encap is applied for forwarded packets, but not for locally-generated packets. This is because the output function is not overridden in __mkroute_output, unlike it is in __mkroute_input. The lwtunnel state is correctly set on the rth through the call to rt_set_nexthop, so all that needs to be done is to override the dst output function to be lwtunnel_output if there is lwtunnel state present and it requires output redirection. Signed-off-by:
-
Robert Shearman authored
In the locally-generated packet path skb->protocol may not be set and this is required for the lwtunnel encap in order to get the lwtstate. This would otherwise have been set by ip_output or ip6_output so set skb->protocol prior to calling the lwtunnel encap function. Additionally set skb->dev in case it is needed further down the transmit path. Signed-off-by:

Since the introduction of the BPF action in d23b8ad8 ("tc: add BPF based action"), late binding was not working as expected. I.e. setting the action part for a classifier only via 'bpf index <num>', where <num> is the index of an existing action, is being rejected by the kernel due to other missing parameters. It doesn't make sense to require these parameters such as BPF opcodes etc, as they are not going to be used anyway: in this case, they're just allocated/parsed and then freed again w/o doing anything meaningful. Instead, parse and verify the remaining parameters *after* the test on tcf_hash_check(), when we really know that we're dealing with creation of a new action or replacement of an existing one and where late binding is thus irrelevant. After patch, test case is now working: FOO="1,6 0 0 4294967295," tc actions add action bpf bytecode "$FOO" tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action bpf index 1 tc actions show action bpf action order 0: bpf bytecode '1,6 0 0 4294967295' default-action pipe index 1 ref 2 bind 1 tc filter show dev foo filter protocol all pref 49152 bpf filter protocol all pref 49152 bpf handle 0x1 flowid 1:1 bytecode '1,6 0 0 4294967295' action order 1: bpf bytecode '1,6 0 0 4294967295' default-action pipe index 1 ref 2 bind 1 Late binding of a BPF action can be useful for preloading maps (e.g. before they hit traffic) in case of eBPF programs, or to share a single eBPF action with multiple classifiers.

Before this patch when a vid was not specified, the entry was added with vid 0 which is useless when vlan_filtering is enabled. This patch makes the entry to be added on all configured vlans when vlan filtering is enabled and respectively deleted from all, if the entry vid is 0. This is also closer to the way fdb works with regard to vid 0 and vlan filtering. Example: Setup: $ bridge vlan add vid 256 dev eth4 $ bridge vlan add vid 1024 dev eth4 $ bridge vlan add vid 64 dev eth3 $ bridge vlan add vid 128 dev eth3 $ bridge vlan port vlan ids eth3 1 PVID Egress Untagged 64 128 eth4 1 PVID Egress Untagged 256 1024 $ echo 1 > /sys/class/net/br0/bridge/vlan_filtering Before: $ bridge mdb add dev br0 port eth3 grp 239.0.0.1 $ bridge mdb dev br0 port eth3 grp 239.0.0.1 temp After: $ bridge mdb add dev br0 port eth3 grp 239.0.0.1 $ bridge mdb dev br0 port eth3 grp 239.0.0.1 temp vid 1 dev br0 port eth3 grp 239.0.0.1 temp vid 128 dev br0 port eth3 grp 239.0.0.1 temp vid 64 Signed-off-by:

Straightforward patch to add GRO processing to virtio_net. napi_complete_done() usage allows more aggressive aggregation, opted-in by setting /sys/class/net/xxx/gro_flush_timeout Tested: Setting /sys/class/net/xxx/gro_flush_timeout to 1000 nsec, Rick Jones reported following results. One VM of each on a pair of OpenStack compute nodes with E5-2650Lv3 CPUs and Intel 82599ES-based NICs. So, two "before" and two "after" VMs. The OpenStack compute nodes were running OpenStack Kilo, with VxLAN encapsulation being used through OVS so no GRO coming-up the host stack. The compute nodes themselves were running a 3.14-based kernel. Single-stream netperf, CPU utilizations and thus service demands are based on intra-guest reported CPU.

Add skb->hash to the __sk_buff offset map, so it can be accessed from an eBPF program. We currently already do this for classic BPF filters, but not yet on eBPF, it might be useful as a demuxer in combination with helpers like bpf_clone_redirect(), toy example: __section("cls-lb") int ingress_main(struct __sk_buff *skb) { unsigned int which = 3 + (skb->hash & 7); /* bpf_skb_store_bytes(skb, ...); */ /* bpf_l{3,4}_csum_replace(skb, ...); */ bpf_clone_redirect(skb, which, 0); return -1; } I was thinking whether to add skb_get_hash(), but then concluded the raw skb->hash seems fine in this case: we can directly access the hash w/o extra eBPF helper function call, it's filled out by many NICs on ingress, and in case the entropy level would not be sufficient, people can still implement their own specific sw fallback hash mix anyway.
