We keep IB device structures around until the last sysfs reference is
gone, but we shouldn't ask the low-level driver to do anything after
the LLD unregisters the device. To handle this, check the reg_state
field and just fail sysfs show() requests if the device has already
been unregistered.

SMACK (Stuttgart Modified Amateurradio CRC KISS) is a KISS variant that

It's also used to communicate over a pty to applications such as Wampes.

From Suzanne Wood <suzannew@cs.pdx.edu>:
Clarify RCU implementation in bpqether.c.
Because bpq_new_device() calls list_add_rcu() and bpq_free_device() calls
list_del_rcu(), substitute list_for_each_entry_rcu() for
list_for_each_entry() in bpq_get_ax25_dev() and in bpq_seq_start().
Add rcu dereference protection in bpq_seq_next().
The rcu_read_lock()/unlock() in bpq_device_event() are removed because
netdev event handlers are called with RTNL locking in place.
FYI: bpq_free_device() calls list_del_rcu() which, per list.h, requires
synchronize_rcu() which can block or call_rcu() or call_rcu_bh() which
cannot block. Herbert Xu notes that synchronization is done here by
unregister_netdevice(). This calls synchronize_net() which in turn uses
synchronize_rcu().

This patch fixes the following bugs with offline diagnostics
code(run with "ethtool -t").
1. After running offline diagnostics, adapter would report
corrupted packets on receive. This was because of adapter not
being brought out of "RLDRAM test mode".
2. Current EEPROM test works only for Xframe I. Since Xframe II
uses different interface(SPI), support for this interface has
been added. Also, since SPI supports write access to all areas
of EEPROM, negative testing is done only for Xframe I.
3. Return values from subfunctions of offline diagnostics have
been corrected.
4. In register test, expected value from rx_queue_cfg register
is made to depend on adapter type.
5. After the test, need to restore values at EEPROM offsets
0x4F0 and 0x7F0. These locations were modified as part of test.
6. Use macro SPECIAL_REG_WRITE for write access to mc_rldram_test_ctrl
register. Also, couple of unnecessary writes to mc_rldram_test_ctrl
have been removed.

"...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which
I'm using the Vesa FB driver. When the machine has been idle for some
time and the driver attempts to powerdown the display, rather than the
display going blank, it goes gray with several strange lines. When I
hit the "shift" key or other-wise wake up the display, the old video
state is not fully restored..."
vesafb recently added a blank method which has only 2 states, powerup and
powerdown. The powerdown state is used for all blanking levels, but in his
case, powerdown does not work correctly for higher levels of display
powersaving. Thus, for intermediate power levels, use software blanking,
and use only hardware blanking for an explicit powerdown.

During the development of an USB device I found a bug in the handling of
Highspeed HID devices in the kernel.
What happened?
Highspeed HID devices are correctly recognized and enumerated by the
kernel. But even if usbhid kernel module is loaded, no HID reports are
received by the kernel.
The output of the hardware USB analyzer told me that the host doesn't
even poll for interrupt IN transfers (even the "interrupt in" USB
transfer are polled by the host).
After some debugging in hid-core.c I've found the reason.
In case of a highspeed device, the endpoint interval is re-calculated in
driver/usb/input/hid-core.c:
line 1669:
/* handle potential highspeed HID correctly */
interval = endpoint->bInterval;
if (dev->speed == USB_SPEED_HIGH)
interval = 1 << (interval - 1);
Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6).
This new calculated value of "interval" is used as input for
usb_fill_int_urb:
line 1685:
usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0,
hid_irq_in, hid, interval);
Unfortunately the same calculation as above is done a second time in
usb_fill_int_urb in the file include/linux/usb.h:
line 933:
if (dev->speed == USB_SPEED_HIGH)
urb->interval = 1 << (interval - 1);
else
urb->interval = interval;
This means, that if the endpoint descriptor (of a high speed device)
specifies e.g. bInterval = 7, the urb->interval gets the value:
hid-core.c: interval = 1 << (7-1) = 0x40 = 64
urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow
Because of this the value of urb->interval is sometimes negative and is
rejected in core/urb.c:
line 353:
/* too small? */
if (urb->interval <= 0)
return -EINVAL;
The conclusion is, that the recalculaton of the interval (which is
necessary for highspeed) should not be made twice, because this is
simply wrong. ;-)
Re-calculation in usb_fill_int_urb makes more sense, because it is the
most general approach. So it would make sense to remove it from
hid-core.c.
Because in hid-core.c the interval variable is only used for calling
usb_fill_int_urb, it is no problem to remove the highspeed
re-calculation in this file.

Increased use of scatter-gather by usb-storage driver after 2.6.13 has
exposed a buggy codepath in isp116x-hcd, which was probably never
visited before: bug happened only for those urbs, for which
URB_SHORT_NOT_OK was set AND short transfer occurred.
The fix attached was tested in 2 ways: (a) it fixed failing
initialization of a flash drive with an embedded hub; (b) the fix was
tested with 'usbtest' against a modified g_zero driver (on top of
net2280), which generated short bulk IN transfers of various lengths
including multiples and non-multiples of max_packet_length.
