[net-next 1/6] e1000e: locking bug introduced by commit 67fd4fcb

[Jeff Kirsher]

From: Bruce Allan <bruce.w.allan@intel.com>

Commit 67fd4fcb (e1000e: convert to stats64) added the ability to update
statistics more accurately and on-demand through the net_device_ops
.ndo_get_stats64 hook, but introduced a locking bug on 82577/8/9 when
linked at half-duplex (seen on kernels with CONFIG_DEBUG_ATOMIC_SLEEP=y and
CONFIG_PROVE_LOCKING=y).  The commit introduced code paths that caused a
mutex to be locked in atomic contexts, e.g. an rcu_read_lock is held when
irqbalance reads the stats from /sys/class/net/ethX/statistics causing the
mutex to be locked to read the Phy half-duplex statistics registers.

The mutex was originally introduced to prevent concurrent accesses of
resources (the NVM and Phy) shared by the driver, firmware and hardware
a few years back when there was an issue with the NVM getting corrupted.
It was later split into two mutexes - one for the NVM and one for the Phy
when it was determined the NVM, unlike the Phy, should not be protected by
the software/firmware/hardware semaphore (arbitration of which is done in
part with the SWFLAG bit in the EXTCNF_CTRL register).  This latter
semaphore should be sufficient to prevent resource contention of the Phy in
the driver (i.e. the mutex for Phy accesses is not needed), but to be sure
the mutex is replaced with an atomic bit flag which will warn if any
contention is possible.

Also add additional debug output to help determine when the sw/fw/hw
semaphore is owned by the firmware or hardware.

[net-next 2/6] if_link: Add additional parameter to IFLA_VF_INFO for spoof checking

[Jeff Kirsher]

From: Greg Rose <gregory.v.rose@intel.com>

Add configuration setting for drivers to turn spoof checking on or off
for discrete VFs.

v2 - Fix indentation problem, wrap the ifla_vf_info structure in
     #ifdef __KERNEL__ to prevent user space from accessing and
     change function paramater for the spoof check setting netdev
     op from u8 to bool.
v3 - Preset spoof check setting to -1 so that user space tools such
     as ip can detect that the driver didn't report a spoofcheck
     setting.  Prevents incorrect display of spoof check settings
     for drivers that don't report it.

[net-next 4/6] igb: enable l4 timestamping for v2 event packets

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

When enabling hardware timestamping for ptp v2 event packets, the
software does not setup the queue for l4 packets, although layer 4
packets are valid for v2. This patch adds the flag which enables
setting up a queue and enabling udp packet timestamping.

[net-next 5/6] igb: fix timecompare_upate race condition

[Jeff Kirsher]

From: Jacob Keller <jacob.e.keller@intel.com>

This patch closes a possible race condition when timestamping using
the timecompare_update function as a method to detect clock skew of
the internal cycle counter. Because timecompare_update usually allows
skew detection no more than once a second, if ptpd or other software
performs a clock offset (for example, using the "date" command), there
is a small window of time where the clock skew will not match the
current kernel wall time. This patch forces the timecompare_update to
calculate skew every time we timestamp a packet, which removes the
possibility of this race condition.

NAK.

What will happen when you use the card for the telecom profile?

In that case you can expect 32 sync packets per second (plus delay
requests times number of clients).

A better way is to remove the timecompare stuff and offer a PTP
Hardware Clock instead. That would make the race condition a non-issue
and also enable the nice hardware clock offered by the card(s).

Thanks,
Richard

[net-next 6/6] igbvf: convert to ndo_fix_features

[Jeff Kirsher]

From: Michał Mirosław <mirq-linux@rere.qmqm.pl>

Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM.
Removing this needs deeper surgery.

Things noticed:
 - HW VLAN acceleration probably can be toggled, but it's left as is
 - the resets on RX csum offload change can probably be avoided
 - there is A LOT of copy-and-pasted code here

These four still look like unnecessary churn to me, and possibly the
wrong direction WRT time stamping in the 82580.

But these two look important, so I don't know what to say.

(I apologize for the delayed response--I was out of the office. I've read through the discussions and will respond here in the interest of brevity.)

I still fail to see how they're churn. I'm making the code make sense for what is actually supported today. I understand that, theoretically, some of this work may be reverted if/when we pull out hardware timestamping as a separate feature from the PTP support in the driver, but I don't think we should leave it general because someone someday might get around to doing something with it. It's confusing and more difficult to maintain for no benefit. It should be part of the development effort to generalize and consolidate where possible when adding a feature.

Those two are definitely important. :)

Matthew

Dave-
I see you have set this series to "Changes Requested" in patchworks, and
I am assuming that is from the discussion that occurred on patch 04 of
the series.  That discussion came to the conclusion that changes should
happen in the PTP core, and that the patch is fine as is currently.

If there was something else you want changed, let me/Matthew know so
that we can make the necessary changes.

Cheers,
Jeff

This series contains updates to igb, specifically the PTP code.
There have been no changes since the last pull request other than
the update to the git tree to the latest net-next.

There was discussion on patch 4 of the series which resulted in
a suggested change to the PTP core.  Once these get accepted,
Matthew Vick will continue on with the suggested changes made by
Richard Cochran, Ben Hutchings and Jacob Keller.
  
The following are changes since commit ba01dfe18241bf89b058fd8a60218b218ad2bb30:

Nothing there:

[davem@tempietto net-next]$ git pull git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master
>From git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
 * branch            master     -> FETCH_HEAD
Already up-to-date.
[davem@tempietto net-next]$ 

Now is AN EXTREMELY bad period to waste my time like this.

REALLY Sorry, I forgot to push the patches up to kernel.org.  I have
pushed them up now.

Pulled, thanks Jeff.

[net-next 0/6][pull request] Intel Wired LAN Driver Updates

[Jeff Kirsher]

This series contains updates to e1000, igb, ixgbe and ixgbevf.

Hong Zhiguo provides a fix for e1000 where tx_ring and adapter->tx_ring
are already of type "struct e1000_tx_ring" so no need to divide by
e1000_tx_ring size in the idx calculation.

Emil provides a fix for ixgbevf to remove a redundant workaround related
to header split and a fix for ixgbe to resolve an issue where the MTA table
can be cleared when the interface is reset while in promisc mode.

Todd provides a fix for igb to prevent ethtool from writing to the iNVM
in i210/i211 devices.  This issue was reported by Marek Vasut <marex@denx.de>.

Anton Blanchard provides a fix for ixgbe to reduce memory consumption
with larger page sizes, seen on PPC.

Don provides a cleanup in ixgbe to replace the IXGBE_DESC_UNUSED macro with
the inline function ixgbevf_desc_unused() to make the logic a bit more
readable.

The following are changes since commit ba4865027c11d7ac8e5a33e0624dd415caab2027:
  ipv6: remove the unnecessary statement in find_match()
and are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next master

Anton Blanchard (1):
  ixgbe: Reduce memory consumption with larger page sizes

Don Skidmore (1):
  ixgbe: cleanup IXGBE_DESC_UNUSED

Emil Tantilov (2):
  ixgbevf: remove redundant workaround
  ixgbe: fix inconsistent clearing of the multicast table

Fujinaka, Todd (1):
  igb: Don't let ethtool try to write to iNVM in i210/i211

Hong Zhiguo (1):
  e1000: fix wrong queue idx calculation
