Subject: Linux 2.4.25, nfs client hangs when talking to a MacOS nfs server.

Hi all,

i'm facing a very annoying problem with nfs on linux 2.4.25 ( vanilla
kernel ).
I have a MacOS X server ( tried with version 10.2.8 and 10.3.2 ) acting
as an nfs server for a bunch of linux clients ( 2.4.25 vanilla ).
Whenever i try to copy a file from the server to the client, the
process gets stuck after copying a few bytes from the server. This is
systematic.
Looking at the process state gives:

PID PPID WCHAN S
12539 12516 rpc_ex D

nfs mount options are the following : ro,nosuid,nolock
I've also tried to add the soft option, it does not change anything.

After doing some research, i found a patch available for linux nfs to
support larger locking cookies ( as used by FreeBsd and MaxOSX ) but as
far as i understant, this should not be the cause of my problem since
i'm mounting readonly and also i secified the nolock option to mount.

Does anyone have an idea of what's happening ? Is is a problem specific
to interactions between Linux & MacOS ? I could not find any info about
this on the net.
Thanks in advance for any help.

I've turned on debugging for nfs ( setting /proc/sys/sunrpc/*_debug to
9 ) and i'm getting the following logs:

Your Mac server is replying slooooooooowwwwwwwwllllllllllyyyyyyyyyyy.
That either indicates that you have a dirty network which is losing
packets (can happen if you are mixing 10Mbps and 100Mbps segments) or
the Mac server is hanging.

Hi Trond,
thanks for the quick reply.
As you pointed out i've got a network which mixes 100Mbps and 1Gbps (
the mac is on 1Gps and the linux on 100Mbps ).
However i've done a little troubleshooting on the network and i achieve
full 100Mbps speed scp'ing files from/to both machines.
I've also tried to use nfs over tcp instead of udp and it does not
change anything.
I've got a Gigabit card for the Linux box and i've scheduled to install
it within the next few days. I'll see if this helps or not.
In the meantime, any other hint is welcome.
Thanks.

Subject: arithmetic functions for linux driver

Hi,
I am new to linux world and this mailing list.

I need to use the arithmetic functions like sin, cos,
exp, log, etc in linux device driver.

On search read , not to use libm from kernel driver
as it will harm the fpu registers.

Do you have any insight how to support these
functions in linux driver or any code that is
available which I can make use of?

thanks
vinod

What exactly are you trying to do? Why not simply create a look up
table for the functions you need, if the expected range of input
values is small?

The range of input is varying.
Iam looking for floating point arithmetic functions
like log10, pow , sin ,exp , cos etc.

There are at least three problems.
(1) The kernel does not save and restore FPU registers across
system calls, only context-switches. This means that you will
probably break some user-mode code that is using the FPU.
You could, of course, save then restore the FPU state in your
code. However, there are other problems, read on.

(2) Some versions of the GCC compiler rely on the floating-
point library and do not generate FPU instructions in-line.
You absolutely-positively cannot link your kernel code against
such a library. The shared libraries don't even exist from
within the kernel, and the static library assumes user-mode
code.

(3) The use of FP within the kernel means that you have
lost the reason for a kernel module. Any such code must
execute in user-mode. The Unix/Linux way involves a
task called a daemon. Such a task does all the user-mode
stuff like floating-point math and file-I/O. It interfaces
with your driver either through the POSIX API (open/close/read/write),
/proc, or sockets.

A Unix/Linux "driver" is NOT anything like a Windows "driver".
Most Windows drivers are not drivers at all, but Libraries!
Such Libraries run in user-mode. Making such a library
in Linux is easy, just compile your library-code and link
against it. You can use any resources other user-mode code
can use.

Like the range of input from an ADC? You get the data in
the kernel and you muck with it in user-mode after you
have it.

If the task in hand is anything much more complicated than getting the
input from an 8-bit ADC, and transforming it using a single function
such as sin, then yes, do it in userspace.

I'd recommend using fixed denominator rational numbers to represent real
numbers and polynomial approximations for the transcendental functions.
We do this in our EBS scheduler patches and it seems to be successful.
The main downside to this approach is the limited range (and
precision) of values that can be represented so you need to have a clear
idea of the likely values at various stages of your calculations.

The "Handbook of Mathematical Functions" by Abramowitz and Stegun, Dover
Publications, New York ISBN 486-61272-4 (LCN 65-12253) is a good source
of methods for approximating functions.

If you'd like more detailed assistance don't hesitate to ask.
