Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not
going to scale if we add any more segmentation methods (e.g., DCCP). So
let's merge them.
They were used to tell the protocol of a packet. This function has been
subsumed by the new gso_type field. This is essentially a set of netdev
feature bits (shifted by 16 bits) that are required to process a specific
skb. As such it's easy to tell whether a given device can process a GSO
skb: you just have to and the gso_type field and the netdev's features
field.
I've made gso_type a conjunction. The idea is that you have a base type
(e.g., SKB_GSO_TCPV4) that can be modified further to support new features.
For example, if we add a hardware TSO type that supports ECN, they would
declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would
have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO
packets would be SKB_GSO_TCPV4. This means that only the CWR packets need
to be emulated in software.

Several problems occured with lcs device driver:
- device not operational anymore after cable pull/plug-in.
- unpredictable results occured, e.g. kernel panic
using cards of type QD8F.
- STOPLAN and delete multicast address command
were not proper recognized by OSA card under heavy network workload.
- channel/device error checks missing in interrupt handler.
To fix all problems at once recovery of lcs devices has been improved.
missing error checks in lcs interrupt handler has been added.
Once a hardware problem occurs lcs will recover the device now properly.

- fix fake_ll during initial device bringup. fake_ll was
not active after first start of the device.
Problem only occured when qeth was built without IPV6 support.
- avoid skb usage after invocation of qeth_flush_buffers,
because skb might already be freed.
- remove yet another useless netif_wake_queue in
qeth_softsetup_ipv6 since this function is only called
when device is going online. In this case card->state will
never be in state UP. So let the net_device queue down .

While debugging why our LCS emulator is having some problems I noticed the

statement is always true since SCHN_STAT_PCI is defined as 0x80.

Hi jeff,
after the first shot I sent to you did not apply I
resend two new patches I've made today to remove tty from ctc network driver.
Please apply ....
Thank you ...
Frank
From: Peter Tiedemann <ptiedem@de.ibm.com>
[1/2]:
tty support code will be removed from the ctc network device driver.
Today we have a couple of alternatives which are performing much
better. The second thing is that ctc should be a network
device driver only.
We should not mix tty and networking here.
This first patch will remove the tty code from ctcmain.c .
It also removes the build entry from the Makefile as well as TTY
definitions from ctcmain.h.
The second patch will remove two files, ctctty.c and ctctty.h.

The API and code have been through various bits of initial review by
serial driver people but they definitely need to live somewhere for a
while so the unconverted drivers can get knocked into shape, existing
drivers that have been updated can be better tuned and bugs whacked out.
This replaces the tty flip buffers with kmalloc objects in rings. In the
normal situation for an IRQ driven serial port at typical speeds the
behaviour is pretty much the same, two buffers end up allocated and the
kernel cycles between them as before.
When there are delays or at high speed we now behave far better as the
buffer pool can grow a bit rather than lose characters. This also means
that we can operate at higher speeds reliably.
For drivers that receive characters in blocks (DMA based, USB and
especially virtualisation) the layer allows a lot of driver specific
code that works around the tty layer with private secondary queues to be
removed. The IBM folks need this sort of layer, the smart serial port
people do, the virtualisers do (because a virtualised tty typically
operates at infinite speed rather than emulating 9600 baud).
Finally many drivers had invalid and unsafe attempts to avoid buffer
overflows by directly invoking tty methods extracted out of the innards
of work queue structs. These are no longer needed and all go away. That
fixes various random hangs with serial ports on overflow.
The other change in here is to optimise the receive_room path that is
used by some callers. It turns out that only one ldisc uses receive room
except asa constant and it updates it far far less than the value is
read. We thus make it a variable not a function call.
I expect the code to contain bugs due to the size alone but I'll be
watching and squashing them and feeding out new patches as it goes.
Because the buffers now dynamically expand you should only run out of
buffering when the kernel runs out of memory for real. That means a lot of
the horrible hacks high performance drivers used to do just aren't needed any
more.
Description:
tty_insert_flip_char is an old API and continues to work as before, as does
tty_flip_buffer_push() [this is why many drivers dont need modification]. It
does now also return the number of chars inserted
There are also
tty_buffer_request_room(tty, len)
which asks for a buffer block of the length requested and returns the space
found. This improves efficiency with hardware that knows how much to
transfer.
and tty_insert_flip_string_flags(tty, str, flags, len)
to insert a string of characters and flags
For a smart interface the usual code is
len = tty_request_buffer_room(tty, amount_hardware_says);
tty_insert_flip_string(tty, buffer_from_card, len);
More description!
At the moment tty buffers are attached directly to the tty. This is causing a
lot of the problems related to tty layer locking, also problems at high speed
and also with bursty data (such as occurs in virtualised environments)
I'm working on ripping out the flip buffers and replacing them with a pool of
dynamically allocated buffers. This allows both for old style "byte I/O"
devices and also helps virtualisation and smart devices where large blocks of
data suddenely materialise and need storing.
So far so good. Lots of drivers reference tty->flip.*. Several of them also
call directly and unsafely into function pointers it provides. This will all
break. Most drivers can use tty_insert_flip_char which can be kept as an API
but others need more.
At the moment I've added the following interfaces, if people think more will
be needed now is a good time to say
int tty_buffer_request_room(tty, size)
Try and ensure at least size bytes are available, returns actual room (may be
zero). At the moment it just uses the flipbuf space but that will change.
Repeated calls without characters being added are not cumulative. (ie if you
call it with 1, 1, 1, and then 4 you'll have four characters of space. The
other functions will also try and grow buffers in future but this will be a
more efficient way when you know block sizes.
int tty_insert_flip_char(tty, ch, flag)
As before insert a character if there is room. Now returns 1 for success, 0
for failure.
int tty_insert_flip_string(tty, str, len)
Insert a block of non error characters. Returns the number inserted.
int tty_prepare_flip_string(tty, strptr, len)
Adjust the buffer to allow len characters to be added. Returns a buffer
pointer in strptr and the length available. This allows for hardware that
needs to use functions like insl or mencpy_fromio.

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

This patch introduces new feature in qeth:
qeth enhancement provides the device driver support for
the Communication Controller for Linux on System z9 and zSeries
(CCL), which is software that enables running the Network Control
Program (NCP) on a zSeries machine. The OSA CDLC support is based
on a new IBM mainframe CHPID type called Open Systems Adaper for
NCP (OSN). In case of OSN qeth communicates with the type-OSN
OSA-card on one hand, and with the CCL-kernel-component Network
Device Handler (NDH) on the other.

minor qeth fixes:
- free old skb in qeth_realloc_headroom after duplicating skb
- disable IPV6 support for Hipersockets devices
- call ccw_device_set_offline on every channel regardless
of the return value of the prior ccw_device_set_offline calls
- allocate qdio structures in DMA-area
- schedule recovery of appropriate card
when cable has been inserted again.
- add missing initialization of card->lock
- write sequence number in skb->cb for SNA protocol which
requires strictly serialized packets.

The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
introduces __in_dev_get_rcu() to cover the second case.
1) RCU with refcnt should use in_dev_get().
2) RCU without refcnt should use __in_dev_get_rcu().
3) All others must hold RTNL and use __in_dev_get_rtnl().
There is one exception in net/ipv4/route.c which is in fact a pre-existing
race condition. I've marked it as such so that we remember to fix it.
This patch is based on suggestions and prior work by Suzanne Wood and
Paul McKenney.

- Clear read channel first prior to using ccw_device_set_offline.
- use QETH_DBF_TEXT instead of QETH_DBF_SPRINTF
- invoke qeth_halt_channel and qeth_clear_channel for all channels,
even if halt/clear for one of the channel fails.
- enable qeth_arp_query function for GuestLAN devices

Jeff,
I'm sorry seems that they have not been sent out either ...
ok here they come ...
[patch 3/4] s390: TSO related fixes in qeth driver
From: Frank Pavlic <pavlic@de.ibm.com>
TSO related fixes :
- changing value of large_send attribute while network traffic
is running caused program check and thus device recovery.
- Due to hardware restriction discard packet when it exceeds 60K
otherwise qeth will cause program checks and thus traffic stall
when trying to send such huge packets.
