Intel Wired LAN Driver Updates 2015-09-22
This series contains updates to e1000, e1000e, igbvf, ixgbe, ixgbevf and
fm10k.
Jacob provides several updates for fm10k, which cleans up comments and
most notably a fix for a corner case issue with the PF/VF mailbox code.
The issue being fm10k_mbx_reset_work clears various states about the
mailbox, but does not clear the Tx FIFO head/tail pointers. We also
are not able to simply clear these pointers, as we would drop
untransmitted messages without error. Also adds support for extra debug
statistics, which provides the ability to see what the PF thinks the
VF mailboxes look like.
Don adds support for SFP+ in X550 and support for SCTP flow director
filters SCTP mask.
Francois Romieu dusts off the e1000 driver and removes some dead calls
to e1000_init_eeprom_params().
Toshiaki Makita provides three patches to enable TSO for stacked VLAN's
on e1000e, igbvf and ixgbevf.
Mark provides the first of several ixgbe updates. First updates the
driver to accept SFP not present error for all devices, since an SFP
can still be inserted. Adds support for SFP insertion interrupt on
X550EM devices with SPFs. Adds I2C combined operations on X550EM
(not X550) devices. Moved the setting of lan_id to before any I2C
eeprom access. Lastly, set the bit bang mode in the hardware when
performing bit banding I2C operations on X550.

bridge: don't age out externally added FDB entries
v3: Per davem review: add del_timer_sync on rocker port remove.
v2: Per Jiri review comment: add BR_DEFAULT_AGEING_TIME to defines
Siva originally proposed skipping externally added FDB entries in the bridge's
FDB garbage collection func, and moving the ageing of externally added entries
to the port driver/device. This broke rocker, since rocker didn't have a
hardware (or software) mechanism for ageing out its learned FDB entries.
This patchset reintroduces Siva's bridge driver patch to skip externally added
entries and adds support in rocker so rocker can age out its own entries.
Rocker does this using a software timer similar to the bridge's FDB garbage
collection timer. Other switchdev devices/drivers can use this software timer
method or program the device to nofity aged-out entries to the driver.

e1000: remove dead e1000_init_eeprom_params calls
The device probe method e1000_probe calls e1000_init_eeprom_params
itself so there's no reason to call it again from e1000_do_write_eeprom
or e1000_do_read_eeprom.
The sentence above assumes that e1000_init_eeprom_params is effective.
e1000_init_eeprom_params depends mostly on hw->mac_type and e1000_probe
bails out early if it can't set mac_type (see e1000_init_hw_struct, then
e1000_set_mac_type), qed.
Btw, if effective, the removed paths would had been deadlock prone when
e1000_eeprom_spi was set:
-> e1000_write_eeprom (takes e1000_eeprom_lock)
-> e1000_do_write_eeprom
-> e1000_init_eeprom_params
-> e1000_read_eeprom (takes e1000_eeprom_lock)
(same narrative with e1000_read_eeprom -> e1000_do_read_eeprom etc.)
As a final note, the candidate deadlock above can't happen in e1000_probe
due to the way eeprom->word_size is set / tested.

fm10k: add support for extra debug statistics
Add a private ethtool flag to enable display of these statistics, which
are generally less useful. However, sometimes it can be useful for
debugging purposes. The most useful portion is the ability to see what
the PF thinks the VF mailboxes look like.

fm10k: create "correct" header for the remote end on connect
When we connect to the mailbox, we insert a fake disconnect header so
that the code does not see an invalid header and thus instantly error
every time we bring up the mailbox. However, we incorrectly record the
tail and head from the local perspective. Since the remote end shouldn't
have anything for us, add a "create_fake_disconnect_hdr" function which
inverts the TAIL and HEAD fields. This enables us to connect without any
errors of either TAIL or HEAD incorrectness, and prevents creating
extraneous error messages. This is necessary now since mbx_reset_work
does not actually reset the Tx FIFO head and tail pointers, thus head
and tail might not be equivalent on a reconnect.

fm10k: drop transmitted messages in Tx FIFO as part of reset_work
This patch fixes a corner case issue with the PF/VF mailbox code.
Currently, fm10k_mbx_reset_work clears various state about the mailbox.
However, it does not clear the Tx FIFO head/tail pointers. We can't
simply clear these pointers as we unintentionally drop untransmitted
messages without error.
Doing nothing results in a possible phantom re-transmission of messages,
since we leave tx.head and tx.tail intact, but clear the tx_pulled and
tail_len values. This means that the PF could continuously re-send a
message which triggers a reset in the VF. Upon reset, the VF will
re-receive the same message after a reconnect.
If we reset the tx.head and tx.tail pointers completely, we end up
dropping some messages that were pending before connect. This results in
missing LPORT_MSG_READY bits, and VFs will end up reporting no link.
However, we can resolve both issues by simply incrementing head to
account for the already transmitted messages, before we reset tx_pulled.
We do this via the same logic as fm10k_mbx_head_pull.
We account for the tail_len which includes all data not yet transmitted,
once we account for the acked data which means re-reading the HEAD
variable from the message header. Then, we drop messages until we've
dropped more than the new tx_pulled value. At this point, resetting
tail_len and tx_pulled, but not tx.head and tx.tail will result in
prevention of the phantom message. It also prevents us from dropping
untransmitted messages upon attempting to Tx into a connect or
disconnect header.

====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next tree
in this 4.4 development cycle, they are:
1) Schedule ICMP traffic to IPVS instances, this introduces a new schedule_icmp
proc knob to enable/disable it. By default is off to retain the old
behaviour. Patchset from Alex Gartrell.
I'm also including what Alex originally said for the record:
"The configuration of ipvs at Facebook is relatively straightforward. All
ipvs instances bgp advertise a set of VIPs and the network prefers the
nearest one or uses ECMP in the event of a tie. For the uninitiated, ECMP
deterministically and statelessly load balances by hashing the packet
(usually a 5-tuple of protocol, saddr, daddr, sport, and dport) and using
that number as an index (basic hash table type logic).
The problem is that ICMP packets (which contain really important
information like whether or not an MTU has been exceeded) will get a
different hash value and may end up at a different ipvs instance. With no
information about where to route these packets, they are dropped, creating
ICMP black holes and breaking Path MTU discovery. Suddenly, my mom's
pictures can't load and I'm fielding midday calls that I want nothing to do
with.
To address this, this patch set introduces the ability to schedule icmp
packets which is gated by a sysctl net.ipv4.vs.schedule_icmp. If set to 0,
the old behavior is maintained -- otherwise ICMP packets are scheduled."
2) Add another proc entry to ignore tunneled packets to avoid routing loops
from IPVS, also from Alex.
3) Fifteen patches from Eric Biederman to:
* Stop passing nf_hook_ops as parameter to the hook and use the state hook
object instead all around the netfilter code, so only the private data
pointer is passed to the registered hook function.
* Now that we've got state->net, propagate the netns pointer to netfilter hook
clients to avoid its computation over and over again. A good example of how
this has been simplified is the former TEE target (now nf_dup infrastructure)
since it has killed the ugly pick_net() function.
There's another round of netns updates from Eric Biederman making the line. To
avoid the patchbomb again to almost all the networking mailing list (that is 84
patches) I'd suggest we send you a pull request with no patches or let me know
if you prefer a better way.
