After the randomization of TCP timestamp offsets
in commit 8a5bd45f6616 (tcp: randomize tcp timestamp offsets

anymore.

sunvnet: better connection management
These patches remove some problems in handling of carrier state
with the ldmvsw vswitch, remove an xoff misuse in sunvnet, and

The sunvnet netdev is connected to the controlling ldom's vswitch
for network bridging. However, for higher performance between ldoms,
there also is a channel between each client ldom. These connections are
represented in the sunvnet driver by a queue for each ldom. The driver
uses select_queue to tell the stack which queue to use by tracking the mac
addresses on the other end of each port. When a connected ldom shuts down,
the driver receives an LDC_EVENT_RESET and the port is removed from the
driver, thus a queue with no ldom on the other end will never be selected
for Tx.
The driver was trying to reinforce the "don't use this queue" notion with
netif_tx_stop_queue() and netif_tx_wake_queue(), which really should only
be used to signal a Tx queue is full (aka XOFF). This misuse of queue
state resulted in NETDEV WATCHDOG messages and lots of unnecessary calls
into the driver's tx_timeout handler. Simply removing these takes care
of the problem.

When an ldom VM is bound, the network vswitch infrastructure is set up for
it, but was being forced 'UP' by the userland switch configuration script.
When 'UP' but not actually connected to a running VM, the ipv6 neighbor
probes fail (not a horrible thing) and start cluttering up the kernel logs.
Funny thing: these are debug messages that never actually show up, but
we do see the net_ratelimited messages that say N callbacks were
suppressed.
This patch defers the netif_carrier_on() until an actual link has been
established with the VM, as indicated by receiving an LDC_EVENT_UP from
the underlying LDC protocol. Similarly, we take the link down when we
see the LDC_EVENT_RESET. Now when we see the ndo_open(), we reset the
link to get things talking again.

All IRQs owned by the PF and VF drivers share the same nondescript name
"octeon"; this makes it difficult to setup interrupt affinity.
Change the IRQ names to reflect their specific purpose:
LiquidIO<id>-<func>-<type>-<queue pair num>
Examples:
LiquidIO0-pf0-rxtx-3
LiquidIO1-vf1-rxtx-0
LiquidIO0-pf0-aux
We cannot use netdev->name for naming the IRQs because:
1. Early during init, the PF and VF drivers require interrupts to
send/receive control data from the NIC firmware; so the PF and VF
must request IRQs long before the netdev struct is registered.
2. The IRQ name can only be specified at the time it is requested.
It cannot be changed after that.

I recently reported on the netem list that iperf network benchmarks
show unexpected results when a bandwidth throttling rate has been
configured for netem. Specifically:
1) The measured link bandwidth *increases* when a higher delay is added
2) The measured link bandwidth appears higher than the specified limit
3) The measured link bandwidth for the same very slow settings varies significantly across
machines
The issue can be reproduced by using tc to configure netem with a
512kbit rate and various (none, 1us, 50ms, 100ms, 200ms) delays on a
veth pair between network namespaces, and then using iperf (or any
other network benchmarking tool) to test throughput. Complete detailed
instructions are in the original email chain here:
https://lists.linuxfoundation.org/pipermail/netem/2017-February/001672.html
There appear to be two underlying bugs causing these effects:
- The first issue causes long delays when the rate is slow and no
delay is configured (e.g., "rate 512kbit"). This is because SKBs are
not orphaned when no delay is configured, so orphaning does not
occur until *after* the rate-induced delay has been applied. For
this reason, adding a tiny delay (e.g., "rate 512kbit delay 1us")
dramatically increases the measured bandwidth.
- The second issue is that rate-induced delays are not correctly
applied, allowing SKB delays to occur in parallel. The indended
approach is to compute the delay for an SKB and to add this delay to
the end of the current queue. However, the code does not detect
existing SKBs in the queue due to improperly testing sch->q.qlen,
which is nonzero even when packets exist only in the
rbtree. Consequently, new SKBs do not wait for the current queue to
empty. When packet delays vary significantly (e.g., if packet sizes
are different), then this also causes unintended reordering.
I modified the code to expect a delay (and orphan the SKB) when a rate
is configured. I also added some defensive tests that correctly find
the latest scheduled delivery time, even if it is (unexpectedly) for a
packet in sch->q. I have tested these changes on the latest kernel
(4.11.0-rc1+) and the iperf / ping test results are as expected.

mlxsw: Enable VRF offload
Ido says:
Packets received from netdevs enslaved to different VRF devices are
forwarded using different FIB tables. In the Spectrum ASIC this is
achieved by binding different router interfaces (RIFs) to different
virtual routers (VRs). Each RIF represents an enslaved netdev and each
VR has its own FIB table according to which packets are forwarded.
The first three patches add an helper to check if a FIB rule is a
default rule and extend the FIB notification chain to include the rule's
info as part of the RULE_{ADD,DEL} events. This allows offloading
drivers to sanitize the rules they don't support and flush their tables.
The fourth patch introduces a small change in the VRF driver to allow
capable drivers to more easily offload VRFs.
Finally, the last patches gradually add support for VRFs in the mlxsw
driver. First, on top of port netdevs, stacked LAG and VLAN devices and
then on top of bridges.
Some limitations I would like to point out:
1) The old model where 'oif' / 'iif' rules were programmed for each L3
master device isn't supported. Upon insertion of these rules the driver
will flush its tables and forwarding will be done by the kernel instead.
It's inferior in every way to the single 'l3mdev' rule, so this shouldn't
be an issue.
2) Inter-VRF routes pointing to a VRF device aren't offloaded. Packets
hitting these routes will be forwarded by the kernel. Inter-VRF routes
pointing to netdevs enslaved to a different VRF are offloaded.
3) There's a small discrepancy between the kernel's datapath and the
device's. By default, packets forwarded by the kernel first do a lookup
in the local table and then in the VRF's table (assuming no match). In
the device, lookup is done only in the VRF's table, which is probably
the intended behavior. Changes in v2 allow user to properly re-order the
default rules without triggering the abort mechanism.
Changes in v3:
* Remove 'l3mdev' from the matchall list, as it's related to the action
and not the selector (David Ahern).
* Use container_of() instead of typecasting (David Ahern).
* Add David's Acked-by to the second patch.
* Add an helper in IPv4 code to check if rule is a default rule (David
Ahern).
Changes in v2:
* Drop default rule indication and allow re-ordering of default rules
(David Ahern).
* Remove ifdef around 'struct fib_rule_notifier_info' and drop redundant
dependency on IP_MULTIPLE_TABLES from rocker and mlxsw.
* Add David's Acked-by to the fourth patch.
* Remove netif_is_vrf_master() and use netif_is_l3_master() instead
(David Ahern).

However, we merely sent a RULE_ADD notification in case custom rules

anymore. Instead, we should notify the caller about all the FIB rules
and let it act accordingly.
Upon registration to the FIB notification chain, replay a RULE_ADD

Whenever a FIB rule is added or removed, a notification is sent in the
FIB notification chain. However, listeners don't have a way to tell
which rule was added or removed.
This is problematic as we would like to give listeners the ability to
decide which action to execute based on the notified rule. Specifically,
offloading drivers should be able to determine if they support the
reflection of the notified FIB rule and flush their LPM tables in case
they don't.
Do that by adding a notifier info to these notifications and embed the
common FIB rule struct in it.

Currently, when non-default (custom) FIB rules are used, devices capable
of layer 3 offloading flush their tables and let the kernel do the
forwarding instead.
When these devices' drivers are loaded they register to the FIB
notification chain, which lets them know about the existence of any
custom FIB rules. This is done by sending a RULE_ADD notification based
on the value of 'net->ipv4.fib_has_custom_rules'.
This approach is problematic when VRF offload is taken into account, as
upon the creation of the first VRF netdev, a l3mdev rule is programmed
to direct skbs to the VRF's table.
Instead of merely reading the above value and sending a single RULE_ADD
notification, we should iterate over all the FIB rules and send a
detailed notification for each, thereby allowing offloading drivers to
sanitize the rules they don't support and potentially flush their
tables.
While l3mdev rules are uniquely marked, the default rules are not.
Therefore, when they are being notified they might invoke offloading
drivers to unnecessarily flush their tables.
Solve this by adding an helper to check if a FIB rule is a default rule.
Namely, its selector should match all packets and its action should
point to the local, main or default tables.
As noted by David Ahern, uniquely marking the default rules is
insufficient. When using VRFs, it's common to avoid false hits by moving
the rule for the local table to just before the main table:
Default configuration:
$ ip rule show
0: from all lookup local
32766: from all lookup main
32767: from all lookup default
Common configuration with VRFs:
$ ip rule show
1000: from all lookup [l3mdev-table]
32765: from all lookup local
32766: from all lookup main
32767: from all lookup default
