16 hours agoImplement RSS hashing/re-hashing for IPv6 ingress packets.
adrian [Sat, 29 Aug 2015 07:14:29 +0000 (07:14 +0000)]
Implement RSS hashing/re-hashing for IPv6 ingress packets.

This mirrors the basic IPv4 implementation - IPv6 packets under RSS
now are checked for a correct RSS hash and if one isn't provided,
it's done in software.

This only handles the initial receive - it doesn't yet handle
reinjecting / rehashing packets after being decapsulated from
various tunneling setups.  That'll come in some follow-up work.

For non-RSS users, this is almost a giant no-op.

It does change a couple of ipv6 methods to use const mbuf * instead of
mbuf * but it doesn't have any functional changes.

So, the following now occurs:

* If the NIC doesn't do any RSS hashing, it's all done in software.
  Single-queue, non-RSS NICs will now have the RX path distributed
  into multiple receive netisr queues.

* If the NIC provides the wrong hash (eg only IPv6 hash when we needed
  an IPv6 TCP hash, or IPv6 UDP hash when we expected IPv6 hash)
  then the hash is recalculated.

* .. if the hash is recalculated, it'll end up being injected into
  the correct netisr queue for v6 processing.

Remove weighted page handling from vm_page_advise().

Now that the pagedaemon performs steady scanning of the active page queue,

2 days agoReplay r286410. Change KPI of how device drivers that provide wireless
glebius [Thu, 27 Aug 2015 08:56:39 +0000 (08:56 +0000)]
Replay r286410. Change KPI of how device drivers that provide wireless
connectivity interact with the net80211 stack.

Historical background: originally wireless devices created an interface,
just like Ethernet devices do. Name of an interface matched the name of
the driver that created. Later, wlan(4) layer was introduced, and the
wlanX interfaces become the actual interface, leaving original ones as
"a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer
and a driver became a mix of methods that pass a pointer to struct ifnet
as identifier and methods that pass pointer to struct ieee80211com. From
user point of view, the parent interface just hangs on in the ifconfig
list, and user can't do anything useful with it.

Now, the struct ifnet goes away. The struct ieee80211com is the only
KPI between a device driver and net80211. Details:

- The struct ieee80211com is embedded into drivers softc.
- Packets are sent via new ic_transmit method, which is very much like
  the previous if_transmit.
- Bringing parent up/down is done via new ic_parent method, which notifies
  driver about any changes: number of wlan(4) interfaces, number of them
  in promisc or allmulti state.
- Device specific ioctls (if any) are received on new ic_ioctl method.
- Packets/errors accounting are done by the stack. In certain cases, when
  driver experiences errors and can not attribute them to any specific
  interface, driver updates ic_oerrors or ic_ierrors counters.

Details on interface configuration with new world order:
- A sequence of commands needed to bring up wireless DOESN"T change.
- /etc/rc.conf parameters DON'T change.
- List of devices that can be used to create wlan(4) interfaces is
  now provided by net.wlan.devices sysctl.

Most drivers in this change were converted by me, except of wpi(4),
that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing
changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann,
Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in
