Allan, Bruce W [Wed, 13 Apr 2011 13:09:10 +0000]
ethtool: allow custom interval for physical identification

When physical identification of an adapter is done by toggling the
mechanism on and off through software utilizing the set_phys_id operation,
it is done with a fixed duration for both on and off states.  Some drivers
may want to set a custom duration for the on/off intervals.  This patch
changes the API so the return code from the driver's entry point when it
is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to
cycle the on/off states, and updates the drivers that have already been
converted to use the new set_phys_id and use the synchronous method for
identifying an adapter.

The physical identification frequency set in the updated drivers is based
on how it was done prior to the introduction of set_phys_id.

Compile tested only.  Also fixes a compiler warning in sfc.

v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE
v3: fold patchset into single patch and cleanup per Ben's feedback

8 years agoipv4: Call fib_select_default() only when actually necessary.
David S. Miller [Thu, 14 Apr 2011 21:49:37 +0000]
ipv4: Call fib_select_default() only when actually necessary.

fib_select_default() is a complete NOP, and completely pointless
to invoke, when we have no more than 1 default route installed.

And this is far and away the common case.

So remember how many prefixlen==0 routes we have in the routing
table, and elide the call when we have no more than one of those.

This cuts output route creation time by 157 cycles on Niagara2+.

In order to add the new int to fib_table, we have to correct the type
of ->tb_data[] to unsigned long, otherwise the private area will be
unaligned on 64-bit systems.

John Fastabend [Mon, 4 Apr 2011 04:29:41 +0000]
ixgbe: DCB, misallocated packet buffer size with X540 device

The X540 device has a smaller packet buffer but the DCB configuration
never took this into account. Under stress this can result in the DMA
engine hanging and TX Unit hang occurring to reset the device. This
patch reworks the packet buffer allocation routine used for DCB on
82599 and X540 devices to account for RX packet buffer sizes.

This fixes the immediate hang. We should consolidate the various
hardware specific routines for configuring features into a single
routine. This will make it much harder to miss feature cases like
this.

8 years agoe1000e: If ASPM L0s needs to be disabled, do it prior to enabling device
Bruce Allan [Thu, 24 Mar 2011 03:09:03 +0000]
e1000e: If ASPM L0s needs to be disabled, do it prior to enabling device

Based on a patch from Naga Chumbalkar <nagananda.chumbalkar@hp.com>:

If ASPM L0s needs to be disabled due to HW errata, do it prior to
"enabling" the device. This way if the kernel ever defaults its
aspm_policy to POLICY_POWERSAVE, then the e1000e driver will get a
chance to disable ASPM on the misbehaving device *prior* to calling
pci_enable_device_mem(). This will be useful in situations
where the BIOS indicates ASPM support on the server by clearing the
ACPI FADT "ASPM Controls" bit.

Note:
The kernel (2.6.38) currently uses the BIOS "default" as its aspm_policy.
However, Linux distros can diverge from that and set the default to
"powersave".

v2: o cleanup namespace pollution of e1000e_disable_aspm(),
    o fix type and initialization of the new aspm_disable_flag in a few
      functions, and
    o redefine FLAG2_DISABLE_ASPM_L0S to the first unused bit in
      adapter->flags2.

tg3: Dump registers when status block shows errors

This patch monitors the error bit of the status word within the status
block.  If it is set, the driver will dump the driver state after
validating the error and then reset the chip.

When the RX network flow classification interface was originally

not given distinct flow class codes (apparently because the Sun

compatibility, flow hash operations should continue to support the

8 years agostmmac: fix Transmit Underflow error
Giuseppe CAVALLARO [Sun, 10 Apr 2011 23:16:46 +0000]
stmmac: fix Transmit Underflow error

On some old MAC chips without COE sometime the
Transmit Underflow error is issued.

The driver aborted all the transmission process
and initialized it from scratch.
This breaks the network activity as raised by Nachiketa
on a SPEAr board.

The patch is to fix this rare underflow event.
The driver will only clear the interrupt and the Tx
DMA will go out the Suspend state as soon as the
descriptor is fetched again.
The driver will continue to bump-up the DMA FIFO threshold
that, indeed, helped somebody to prevent this kind of error
in the past as well.

pci: fix PCI bus allocation alignment handling

In commit 13583b16592a ("PCI: refactor io size calculation code") Ram
had a thinko in the refactorization of the code: the end result used the
variable 'align' for the bus alignment, but the original code used
'min_align'.

Since then, another use of that 'align' variable got introduced by
commit c8adf9a3e873 ("PCI: pre-allocate additional resources to devices
only after successful allocation of essential resources.")

Fix both of those uses to use 'min_align' as they should.

If the MAC features can be detected at probe time and not at open, then
stmmac_fix_features could be simplified by limiting hw_features. That's
also better for users as they don't see offloads being togglable but
never turned on.

Redundant fallbacks for TX csum are removed as it's already handled

8 years agoDisable rp_filter for IPsec packets
Michael Smith [Thu, 7 Apr 2011 04:51:51 +0000]
Disable rp_filter for IPsec packets

The reverse path filter interferes with IPsec subnet-to-subnet tunnels,
especially when the link to the IPsec peer is on an interface other than
the one hosting the default route.

With dynamic routing, where the peer might be reachable through eth0
today and eth1 tomorrow, it's difficult to keep rp_filter enabled unless
fake routes to the remote subnets are configured on the interface
currently used to reach the peer.

IPsec provides a much stronger anti-spoofing policy than rp_filter, so
this patch disables the rp_filter for packets with a security path.
