      rndis_host learns ActiveSync basics · ad55d71a
      由 Ole Andre Vadla Ravnas 提交于 
      Windows Mobile 5 based devices described as supporting "ActiveSync":

 - Speak RNDIS but lack the CDC and union descriptors.  This patch
   updates the cdc ethernet code to fake ACM descriptors we need.

 - Require RNDIS_MSG_QUERY messages to include a buffer of the size the
   response should generate.  This patch updates the rndis host code to
   pass this will-be-ignored data.

The resulting RNDIS host code has been reported to work with several
WM5 based devices.

(Note that a fancier patch is available at synce.sf.net.)


Some bugfixes, affecting not just ActiveSync:
    (a)	when cleaning up after RNDS init fails, scrub the second interface
	just like cdc_ether does, so disconnect won't oops.
    (b)	handle peripherals that use the pad-to-end-of-packet option; some
	devices can't talk to us if that option doesn't work.
    (c)	when choosing configurations, don't forget about an RNDIS config
	just because the RNDIS driver is dynamically linked.

Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update.
Also for paranoia's sake, refuse to talk to something that looks like a
real modem instead of RNDIS.

      USB: rndis_host: fix crash while probing a Nokia S60 mobile · deb31f17
      由 Daniel Gollub 提交于 
      Bug fix for driver rndis_host which fixes rndis_host probing certain
Nokia S60 (Series 60) mobiles. While the rndis_host get probed by usbnet
and tries to bind the Nokia mobile the bind is going to fail. The
rndis_host module tries to release the device, in a wrong way, which
cause the oops.

Fixes Bugzilla #7201

      USB: asix: Detect internal PHY and enable/use accordingly · d0ffff8f
      由 Andres Salomon 提交于 
      Different AX88772 dongles use different PHYs; the chip is capable of using
both a primary and secondary PHY, and supports an internal and external PHY.

It appears that some DUB-E100 devices use the internal PHY, so trying to use
an external one will not work (note that this is different across revisions,
as well; the "A" and "B" revs of the DUB-E100 use different PHYs!).  The data
sheet for the AX88772 chip specifies that the internal PHY id will be 0x10,
so if that's read from the EEPROM, we should use that rather than attempting
to use an external PHY.

Thanks to Mitch Bradley for pointing this out!

      USB: use MII hooks only if CONFIG_MII is enabled · 18ee91fa
      由 David Brownell 提交于 
      Fix mcs7830 patch

The recent mcs7830 update to make the MII support sharable goofed various
pre-existing configurations in two ways:

  - it made the usbnet infrastructure reference MII symbols even
    when they're not needed in the kernel being built

  - it didn't enable MII along with the mcs7830 minidriver

This patch fixes these two problems.

However, there does seem to be a Kconfig reverse dependency bug in that MII
gets wrongly enabled in some cases (like USBNET=y and USBNET_MII=n); I think
I've noticed that same problem in other situations too.  So the result can
mean kernels being bloated by stuff that's needlessly enabled ... better
than wrongly being disabled, but contributing to bloat.

      IRQ: Maintain regs pointer globally rather than passing to IRQ handlers · 7d12e780
      由 David Howells 提交于 
      Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

      [PATCH] USB: add ZyXEL vendor/product ID to rtl8150 driver · b6c2799d
      由 Dan Streetman 提交于 
      I just got a "ZyXEL Prestige USB Adapter" that is actually RTL8150
adapter.  Here is the relevant /proc/bus/usb/devices output (after
adding the vendor/product IDs to the driver):

T:  Bus=01 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#=119 Spd=12  MxCh= 0

S:  SerialNumber=1027
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=120mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=ff Driver=rtl8150

E:  Ad=02(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=83(I) Atr=03(Int.) MxPS=   8 Ivl=1ms

This patch adds the ZyXEL vendor ID to the rtl8150.c driver.  The
device has absolutely no identifying marks on the outside for model
type, just a serial number, and I can't find anything on ZyXEL's
website, so I called the product ID PRODUCT_ID_PRESTIGE to match the
product string.
