From: Shaun Pereira <spereira@tusc.com.au>
This is the first (independent of the second) patch of two that I am
working on with x25 on linux (tested with xot on a cisco router). Details
are as follows.
Current state of module:
A server using the current implementation (2.6.11.7) of the x25 module will
accept a call request/ incoming call packet at the listening x.25 address,
from all callers to that address, as long as NO call user data is present
in the packet header.
If the server needs to choose to accept a particular call request/ incoming
call packet arriving at its listening x25 address, then the kernel has to
allow a match of call user data present in the call request packet with its
own. This is required when multiple servers listen at the same x25 address
and device interface. The kernel currently matches ALL call user data, if
present.
Current Changes:
This patch is a follow up to the patch submitted previously by Andrew
Hendry, and allows the user to selectively control the number of octets of
call user data in the call request packet, that the kernel will match. By
default no call user data is matched, even if call user data is present.
To allow call user data matching, a cudmatchlength > 0 has to be passed
into the kernel after which the passed number of octets will be matched.
Otherwise the kernel behavior is exactly as the original implementation.
This patch also ensures that as is normally the case, no call user data
will be present in the Call accepted / call connected packet sent back to
the caller
Future Changes on next patch:
There are cases however when call user data may be present in the call
accepted packet. According to the X.25 recommendation (ITU-T 10/96)
section 5.2.3.2 call user data may be present in the call accepted packet
provided the fast select facility is used. My next patch will include this
fast select utility and the ability to send up to 128 octets call user data
in the call accepted packet provided the fast select facility is used. I
am currently testing this, again with xot on linux and cisco.

Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. The current code is not wrong, but it does not account for
early return due to signals, so I think msleep() should be appropriate.

This patch provides support for registering multiple netpoll clients to the
same network device. Only one of these clients may register an rx_hook,
however. In practice, this restriction has not been problematic. It is
worth mentioning, though, that the current design can be easily extended to
allow for the registration of multiple rx_hooks.
The basic idea of the patch is that the rx_np pointer in the netpoll_info
structure points to the struct netpoll that has rx_hook filled in. Aside
from this one case, there is no need for a pointer from the struct
net_device to an individual struct netpoll.
A lock is introduced to protect the setting and clearing of the np_rx
pointer. The pointer will only be cleared upon netpoll client module
removal, and the lock should be uncontested.

This patch introduces a netpoll_info structure, which the struct net_device
will now point to instead of pointing to a struct netpoll. The reason for
this is two-fold: 1) fields such as the rx_flags, poll_owner, and poll_lock
should be maintained per net_device, not per netpoll; and 2) this is a first
step in providing support for multiple netpoll clients to register against the
same net_device.
The struct netpoll is now pointed to by the netpoll_info structure. As
such, the previous behaviour of the code is preserved.

This trivial patch moves the assignment of poll_owner to -1 inside of

After using this facility for a while to test my changes to the
cipher crypt() layer, I realised that I should've listend to Dave
and made this thing use CPU cycle counters :) As it is it's too
jittery for me to feel safe about relying on the results.
So here is a patch to make it use CPU cycles by default but fall
back to jiffies if the user specifies a non-zero sec value.

I recently had the requirement to do some benchmarking on cryptoapi, and
I found reyk's very useful performance test patch [1].
However, I could not find any discussion on why that extension (or
something providing a similar feature but different implementation) was
not merged into mainline. If there was such a discussion, can someone
please point me to the archive[s]?
I've now merged the old patch into 2.6.12-rc1, the result can be found
attached to this email.

CS4236+ driver
Background: The card/chipset supports an external MIDI interrupt. By
default, this interrupt isn't used (because the isapnp mechanism chooses a
configuration without an assigned interrupt). If the user wishes to
explicitly select an interrupt via the mpu_irq parameter for such a
configured device, it doesn't work: The driver always shows:
isapnp MPU: port=0x330, irq=-1
(note the 'irq=-1')
Problem: The driver only allows to set the irq if pnp_irq_valid returns
true for this particular pnp device. This, however, is only true if an
interrupt has already been assigned (pnp_valid_irq returns true if the flag
IORESOURCE_IRQ is set and IORESOURCE_UNSET is not set). If no interrupt
has been assigned so far, IORESOURCE_UNSET is set and pnp_irq_valid returns
false, thereby inhibiting the selection of a valid irq.
Solution: Don't check for a valid (= already assigned) irq at the point of
calling pnp_resource_change.
Tested successfully on Linux 2.6.11.
