commit d90310243fd750240755e217c5faa13e24f41536
Author: Octavian Purdila <opurdila@ixiacom.com>
Date:   Wed Nov 18 02:36:59 2009 +0000

    net: device name allocation cleanups

introduced a bug when there is a hash collision making impossible
to rename a device with eth%d. This bug is very hard to reproduce
and appears rarely.

The problem is coming from we don't pass a temporary buffer to
__dev_alloc_name but 'dev->name' which is modified by the function.

A detailed explanation is here:

rtnetlink: Fix error handling in do_setlink()

Commit c02db8c6290bb992442fec1407643c94cc414375:

Author:  Chris Wright <chrisw@sous-sol.org>
Date:    Sun May 16 01:05:45 2010 -0700
Subject: rtnetlink: make SR-IOV VF interface symmetric

adds broken error handling to do_setlink() in net/core/rtnetlink.c.  The
problem is the following chunk of code:

if (tb[IFLA_VFINFO_LIST]) {
struct nlattr *attr;
int rem;
nla_for_each_nested(attr, tb[IFLA_VFINFO_LIST], rem) {
if (nla_type(attr) != IFLA_VF_INFO)
  ----> goto errout;
err = do_setvfinfo(dev, attr);
if (err < 0)
goto errout;
modified = 1;
}
}

which can get to errout without setting err, resulting in the following error:

net/core/rtnetlink.c: In function 'do_setlink':
net/core/rtnetlink.c:904: warning: 'err' may be used uninitialized in this function

Change the code to return -EINVAL in this case.  Note that this might not be

9 years agonet: fix problem in dequeuing from input_pkt_queue
Tom Herbert [Thu, 20 May 2010 18:37:59 +0000]
net: fix problem in dequeuing from input_pkt_queue

Fix some issues introduced in batch skb dequeuing for input_pkt_queue.
The primary issue it that the queue head must be incremented only
after a packet has been processed, that is only after
__netif_receive_skb has been called.  This is needed for the mechanism
to prevent OOO packet in RFS.  Also when flushing the input_pkt_queue
and process_queue, the process queue should be done first to prevent
OOO packets.

Because the input_pkt_queue has been effectively split into two queues,
the calculation of the tail ptr is no longer correct.  The correct value
would be head+input_pkt_queue->len+process_queue->len.  To avoid
this calculation we added an explict input_queue_tail in softnet_data.
The tail value is simply incremented when queuing to input_pkt_queue.

Alan Stern [Wed, 12 May 2010 22:21:35 +0000]
USB: EHCI: fix controller wakeup flag settings during suspend

This patch (as1380) fixes a bug in the wakeup settings for EHCI host
controllers.  When the controller is suspended, if it isn't enabled
for remote wakeup then we have to turn off all the port wakeup flags.
Disabling PCI PME# isn't good enough, because some systems (Intel)
evidently use alternate wakeup signalling paths.

In addition, the patch improves the handling of the Intel Moorestown
hardware by performing various power-up and power-down delays just
once instead of once for each port (i.e., the delays are moved outside
of the port loops).  This requires extra code, but the total delay
time is reduced.

There are also a few additional minor cleanups.

Anand Gadiyar [Thu, 6 May 2010 14:39:48 +0000]
USB: ehci-omap: Fix resume failures after bus suspend

An undocumented "feature" in the OMAP3 EHCI controller causes
suspended ports to be taken out of suspend when the USBCMD.Run/Stop
bit is cleared (this bit is normally cleared when ehci_bus_suspend
is called).

This "feature" breaks suspend-resume if the root-hub is allowed
to suspend. (The controller thinks it is in resume, and the PHY
thinks it is still in suspend).

There is an undocumented register bit that can be used to disable
this feature and restore normal behavior. Set this bit so
suspend-resume can work normally.

Tested on OMAP3 SDPs with the NXP ISP1504 and NXP ISP1703 PHYs.

This patch (as1379) reworks the logic for handling USB interface
runtime-PM settings -- hopefully it's right this time!  The problem is
that when a driver is unbound or binding fails, runtime PM for the
interface always gets disabled.  But pm_runtime_disable() nests, so it
shouldn't be called unless the interface was previously enabled for

a companion to the EHCI controller on OMAP3 and newer chips.

to keep both drivers around.
