The current X.25 code has some bugs in throughput negotiation:
1. It does negotiation in all cases, usually there is no need
2. It incorrectly attempts to negotiate the throughput class in one
direction only. There are separate throughput classes for input
and output and if either is negotiated both mist be negotiates.
This is bug https://bugzilla.kernel.org/show_bug.cgi?id=15681
This bug was first reported by Daniel Ferenci to the linux-x25 mailing
list on 6/8/2004, but is still present.
The current (2.6.34) x.25 code doesn't seem to know that the X.25
throughput facility includes two values, one for the required
throughput outbound, one for inbound.
This causes it to attempt to negotiate throughput 0x0A, which is
throughput 9600 inbound and the illegal value "0" for inbound
throughput.
Because of this some X.25 devices (e.g. Cisco 1600) refuse to connect
to Linux X.25.
The following patch fixes this behaviour. Unless the user specifies a
required throughput it does not attempt to negotiate. If the user
does not specify a throughput it accepts the suggestion of the remote
X.25 system. If the user requests a throughput then it validates both
the input and output throughputs and correctly negotiates them with
the remote end.

The driver attempts to select an IRQ for the NIC automatically by
testing which of the supported IRQs are available and then probing
each available IRQ with probe_irq_{on,off}(). There are obvious race
conditions here, besides which:
1. The test for availability is done by passing a NULL handler, which
now always returns -EINVAL, thus the device cannot be opened:
<http://bugs.debian.org/566522>
2. probe_irq_off() will report only the first ISA IRQ handled,
potentially leading to a false negative.
There was another bug that meant it ignored all error codes from
request_irq() except -EBUSY, so it would 'succeed' despite this
(possibly causing conflicts with other ISA devices). This was fixed
by ab08999d60 'WARNING: some
request_irq() failures ignored in el2_open()', which exposed bug 1.
This patch:
1. Replaces the use of probe_irq_{on,off}() with a real interrupt handler
2. Adds a delay before checking the interrupt-seen flag
3. Disables interrupts on all failure paths
4. Distinguishes error codes from the second request_irq() call,
consistently with the first
Compile-tested only.

* git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-for-linus:
hvc_console: Fix race between hvc_close and hvc_remove
virtio: disable multiport console support.
virtio: console makes incorrect assumption about virtio API
virtio: console: Fix early_put_chars usage
MAINTAINERS: Put the virtio-console entry in correct alphabetical order
I don't claim to understand the tty layer, but it seems like hvc_open and
hvc_close should be balanced in their kref reference counting.
Right now we get a kref every call to hvc_open:
if (hp->count++ > 0) {
tty_kref_get(tty); <----- here
spin_unlock_irqrestore(&hp->lock, flags);
hvc_kick();
return 0;
} /* else count == 0 */
tty->driver_data = hp;
hp->tty = tty_kref_get(tty); <------ or here if hp->count was 0
But hvc_close has:
tty_kref_get(tty);
if (--hp->count == 0) {
...
/* Put the ref obtained in hvc_open() */
tty_kref_put(tty);
...
}
tty_kref_put(tty);
Since the outside kref get/put balance we only do a single kref_put when
count reaches 0.
The patch below changes things to call tty_kref_put once for every
hvc_close call, and with that my machine boots fine.

As reported in <https://bugzilla.kernel.org/show_bug.cgi?id=15355>, r6040_
multicast_list currently crashes. This is due a wrong maximum of multicast
entries. This patch fixes the following issues with multicast:
- number of maximum entries if off-by-one (4 instead of 3)
- the writing of the hash table index is not necessary and leads to invalid
values being written into the MCR1 register, so the MAC is simply put in a non
coherent state
- when we exceed the maximum number of mutlticast address, writing the
broadcast address should be done in registers MID_1{L,M,H} instead of
MID_O{L,M,H}, otherwise we would loose the adapter's MAC address
