pch_gbe: memory corruption calling pch_gbe_validate_option()

2012-04-22T22:31:14+00:00

commit 73f98eab9b9e0bab492ca06add5657d9e702ddb1 upstream.

pch_gbe_validate_option() modifies 32 bits of memory but we pass
&hw->phy.autoneg_advertised which only has 16 bits and &hw->mac.fc
which only has 8 bits.

pch_gbe: Do not abort probe on bad MAC

2012-04-22T22:31:13+00:00

commit 2b53d07891630dead46d65c8f896955fd3ae0302 upstream.

If the MAC is invalid or not implemented, do not abort the probe. Issue
a warning and prevent bringing the interface up until a MAC is set manually
(via ifconfig $IFACE hw ether $MAC).

Tested on two platforms, one with a valid MAC, the other without a MAC. The real
MAC is used if present, the interface fails to come up until the MAC is set on
the other. They successfully get an IP over DHCP and pass a simple ping and
login over ssh test.

This is meant to allow the Inforce SYS940X development board:
http://www.inforcecomputing.com/SYS940X_ECX.html
(and others suffering from a missing MAC) to work with the mainline kernel.
Without this patch, the probe will fail and the interface will not be created,
preventing the user from configuring the MAC manually.

This does not make any attempt to address a missing or invalid MAC for the
pch_phub driver.

r8169: runtime resume before shutdown.

2012-04-13T15:33:48+00:00

commit 2a15cd2ff488a9fdb55e5e34060f499853b27c77 upstream.

With runtime PM, if the ethernet cable is disconnected, the device is
transitioned to D3 state to conserve energy. If the system is shutdown
in this state, any register accesses in rtl_shutdown are dropped on
the floor. As the device was programmed by .runtime_suspend() to wake
on link changes, it is thus brought back up as soon as the link recovers.

Resuming every suspended device through the driver core would slow things
down and it is not clear how many devices really need it now.

Original report and D0 transition patch by Sameer Nanda. Patch has been
changed to comply with advices by Rafael J. Wysocki and the PM folks.

Fix non TBI PHY access; a bad merge undid bug fix in a previous commit.

[ Upstream commit 464b57da56910c8737ede75ad820b9a7afc46b3e ]

The merge done in commit b26e478f undid bug fix in commit c3e072f8
("net: fsl_pq_mdio: fix non tbi phy access"), with the result that non
TBI (e.g. MDIO) PHYs cannot be accessed.

[ Upstream commit 085f1afc56619bda424941412fdeaff1e32c21dc ]

If port 0 of a 5717 serdes device powers down, it hides the phy from
port 1.  This patch works around the problem by keeping port 0's phy
powered up.

sky2: override for PCI legacy power management

[ Upstream commit 5676cc7bfe1e388e87843f71daa229610385b41e ]

Some BIOS's don't setup power management correctly (what else is
new) and don't allow use of PCI Express power control. Add a special
exception module parameter to allow working around this issue.
Based on slightly different patch by Knut Petersen.

e1000e: Avoid wrong check on TX hang

2012-04-02T16:52:52+00:00

commit 09357b00255c233705b1cf6d76a8d147340545b8 upstream.

Based on the original patch submitted my Michael Wang
.
Descriptors may not be write-back while checking TX hang with flag
FLAG2_DMA_BURST on.
So when we detect hang, we just flush the descriptor and detect
again for once.

-v2 change 1 to true and 0 to false and remove extra ()

As part of the big network driver reorg, each vendor directory defaults to
yes, so that older config's can migrate correctly. Looks like this one
got missed.
