* [PATCH 04/14] [rndis_host] Halt device if rndis_bind fails.
From: Jussi Kivilinna @ 2008-01-20 0:14 UTC (permalink / raw)
To: linux-wireless; +Cc: bjd, dbrownell, netdev
When bind fails after device was initialized, shutdown device properly
by sending RNDIS_MSG_HALT.

RNDIS packet filter flags are not exactly the same as CDC flags
so we cannot reuse them.

Split up rndis_host.c into rndis_host.h and rndis_base.c. This is done so
that rndis_wext can reuse common parts with rndis_host.

Function pointer is for rndis minidrivers that need to do work on device right
after RNDIS_INIT. For example setting device specific configuration parameters
with OID_GEN_RNDIS_CONFIG_PARAMETER.

To: linux-wireless; +Cc: bjd, dbrownell, netdev
Move headers usbnet.h and rndis_host.h to include/linux/usb and fix includes
for drivers/net/usb modules. Headers are moved because rndis_wext will be
outside drivers/net/usb in drivers/net/wireless and yet need these headers.

Looks good Samuel.
Thank you for improving on my original suggested patch.
Now let's hope someone queues it up for mainline :)

The mainline kernel doesn't have ESFQ, so the distribute version of iproute2
does not. If your distro chooses to add ESFQ to their kernel, then they
need to extend tc as well.

I agree, bogus, and in fact I've already removed it from our development
version of ixgbe. Right now I wanted to report I can't remove e1000 at
all on 2.6.24-rc8+git
I continually get the
kernel: unregister_netdevice: waiting for eth2 to become free. Usage
count = 1
Where 2.6.24-rc5 e1000 is okay still. Seems like maybe we are still
missing a netif_rx_complete or a napi_disable somewhere.
I don't think this problem has anything to do with the irq_sem right
now. Something is still badly broken. I am just using the interface
regularly (no heavy load) and I can't unload the module.

Hi David
Thanks for beating into my thick scull that this is in 2.6.25. I missed that
initially.
Anyway, here is a patch that sets the correct value.

Subject: [PATCH] [SCTP] Correctly initialize error when parameter validation failed.
When parameter validation fails, there should be error causes
that specify what type of failure we've encountered. If the
causes are not there, we lacked memory to allocated them. Thus
make that the default value for the error.

That doesn't work in this case since nf_bridge_info contains
unsigned long data[32 / sizeof(unsigned long)];
and I don't want to assign each array element seperately.

Hello,
net 2.6.25 is broken when building with the wireless/iwlwifi
subtree; we get the following errors (we noticed that iwl_down() and
iwl_resume()

so a simple
patch with only adding these two methods might be risky)

* [NET_SCHED 00/09]: sch_ingress cleanups
From: Patrick McHardy @ 2008-01-20 14:32 UTC (permalink / raw)
To: davem; +Cc: netdev, Patrick McHardy, hadi
These patches clean up sch_ingress by reformatting the code to match the
usual kernel style, removing lots of debugging statements that seem
unnecessary after years of stable operation, removing some "future use"
stuff that doesn't seem likely to ever get used and some minor additional
cleanups.
