Try "Understanding Sockets in Unix, NT, and Java" from Kenneth M. Nordby.
You can download it from the IBM-Site:

Subject: sysctl & arrays.
Date: Sat, 28 Apr 2001 20:12:15 +0200
Hi,
In my project I need to use 3 arrays, which the user can change their
value with out compile the kernel again.
While I use only one array, all the project worked well. So I add 2
other array, same definition, different name. The Kernel has been
compiled, with out any error message regarding the arrays. I reboot the
machine, and try
'echo 1 2 3 4 5 6 7 8 > /proc/sys/net/ipv4/myarray2' after some seconds
the kernel fall with the 'killing the idle task'.
I check the definiotn of myarray2, and it is the same as myarray1. I
remove the code which read from myarray2, and the same.
The arrays are in 40 int size. the kernel is 2.2.14-5.0 , i386 machine.
any one have any idea what can cause the kernel falling after
initializing a variable under proc?
{not immediately, I even can make ls a few times, send a ping or two}
another wierd thing I notice that when I read a sysctl value from the
code ) I mean in the kernel-code...) his value is 100*value, any one
have reason for that?
(until now I didn't mind to x/100 any time I needed get the value ;-))
Thanks,
Arie.

I'd say you actually have two problems. The first is the waitpid in the
else clause of the lower fork. This will cause your program to stop and
wait until the child process has stopped before it will fire off the next
child process. The second problem which looks even hairier is that you are
trying to assign each of the middle processes the same pipe as their stdin
and stdout. You need to have a pipe set for each process (actually
I believe you can use n-1 pipe sets) that you fire up. The stdin in for
the next process needs to be assigned the stdout of the previous process
and it's stdout be one of the new pipes, with the last one having it's
stdout be regular stdout (which you do have).
Hope this helped,

Subject: DHCP client broken in 2.4.4
From: Guy Geens <[EMAIL PROTECTED]>
Date: Sun, 29 Apr 2001 15:53:51 GMT
I just tried to upgrade my system from kernel 2.4.3 to 2.4.4. After
reboot, the system could not get a network address from the DHCP
server. The old 2.4.3 kernel works fine.
Both kernels have been compiled with the same options.
When I assign a static IP address to the network card, I can make
connections without problems.
The DCHP client tries to get an IP address from the server, but it
doesn't seem to get any answer. (So it tries again and again...)
When I look in the log files for the DHCP server, I see each request
and the answer being logged and answered.
My network card is a RTL8139 (driver 8139too.c). The DHCP client is
the ISC client, version 2.0pl5. (Taken from Debian woody.)
Any hints on how to fix this are appreciated.
Please CC: me on your replies.

Read the source to gnu mount. You will love all the #ifdef's, looks

do bitwise 'and' (32bit) -8192 to reg.
IOW, the whole thing puts esp & -8192 into reg. Since -8192 is ~8191, that's
esp with 13 lower bits cleared, i.e. esp rounded down to the multiple of 8K.
>put the value of reg to esp then andl $-8192, reg;
It would be, if the idiotic Intel syntax was used. IOW, you got the order
of arguments wrong. E.g.
addl n, %eax
is "add n to eax", or, in Intel syntax,
ADD EAX, [n]
Suffix of the instruction determines the size of arguments (no DWORD PTR for
you), %<register_name> means register, $<number> means constant. IOW,
%eax is register EAX
eax is value of variable called eax
$eax is address of that variable
With binary operations, source goes before the target. That's it.

Date: Sun, 29 Apr 2001 18:43:41 +0100
I'm starting a C++ project which has to compile to form both an MSVC 6
command line application and an RH Linux 6.2 command line application.
I was hoping to use C++ with the Standard Library as described in "The
C++ Programming Language" by Bjarne Stroustrup. WiIl this be
possible ?
I ask, because as soon as I stated adding code to the class skeleton I
found I needed to add a reference to the standard library at link time.
Was I being hopelessly naive in expecting it to be linked by default ?
In the end I found it in:
/usr/lib/gcc-lib/alpha-redhat-linux/egcs-2.91.66/libstdc++.a
but it doesn't seem to be in the default library path so I have to
identify the full path in the Makefile. That stuff now compiles, but is
this normal ?
Now I've added stuff that requires the #include <sstream> according to
Stroustrup. I can find sstream.h, but only in:
/usr/include/linuxconf/sstream.h
which doesn't seem to be in the default include path. When I include
this by giving the full path, the compile fails, complaining that
ostringstream is undeclared, and it does indeed seem to be unmentioned
the linuxconf sstream.h file.
So - a couple of questions:
1) is there a way to get ostringstream to work ?
2) is the Standard C++ library ready for prime time under Linux ?
Isn't its
use utterly routine these days ? Or am I trying to be too modern ?
I'm having no problem getting this stuff to compile under MSVC 6. Have
I missed something obvious under Linux ?
If the compiler that ships with RH6.2 won't do what I need, ( I guess
it must be a year old now ! ), is it simple to upgrade it to a later
gcc that
will ?
If gcc won't work with the standard C++ lib, will the Compaq C for Linux
Alpha compiler be any use ? Will that compiler coexist with the Linux
compiler ? I gather I'd still need that for building kernels !
I've just tried to get an 'on line test drive' to see if the Compaq
compiler would compile my code skeleton, but the link from the Compaq
site is broken.
If I can, I'd rather stay with a standard Linux compiler so that we can
port to Intel Linux if needs be later on.
Cheers, J/.

I'm going to save you some time (because I wasted a lot of my own
before learning what the answer was). ostringstream is not supported
with RH6.2's supplied compiler/libraries. Yes, standard C++ library is
ready for prime time under linux, but it's not an out-of-the-box
experience yet. Yes, stndard C++ is utterly routine (on some platforms-
for example, Tru64 and IRIX, as long as you have $$$). It's a bit
"modern" since the specification was only standardized recently, and
software people have to play catch-up.
If you want standard C++ with the standard C++ library on Linux, and
you are using RH 6.2, then download gcc-2.95.3, compile and install it
according to the instructions, then download STLport-4.0 from
www.stlport.org, and install it according to its instructions. Compile
your apps to use the header files from STLport and link against the
STLport library.
The RH6.2 g++ compiler isn't standard C++ compiliant; gcc-2.95.3 is
nearly enough so (more so than MSVC6 by far) for nearly all code.
Worse, the standard C++ libray they included ISN'T standard. It's
pre-standard, with crap like strstream.h. On the other hand, STLport
is an excellent implementation of the standard C++ library.
RH7.1 comes with a modified g++ compiler, its main issue is that the
ABI it uses is incompatible with the standard g++ library and so when
you try to link apps you have a hard time getting everything to work
properly if you use things like exceptions. As long as you stick to
their compiler, everything will work OK (although you'll pull your hair
out trying to get STLport to compile with their compiler due to
locations of some include files, I have solved this problem, drop me a
line if youwant to know the details).
You might run into some problems because the alpha version of linux
tends to be less well-tested than the intel version, and might not
compile as easily.

Hello,
in the do_irq() function (\arch\i386\kernel\irq.c) do_softirq() is
called.
In do_softirq() (\kernel\softirq.c) interrupts get enabled.
Isn't this possible: do_softirq() can get interrupted bij an IRQ, so
do_irq() is called which finally calls do_softirq(), which gets
interrupted again... and so on...
If not (probably) then what stops this from happening?

This #define creates an assembler macro using AT&T syntax:
The first line moves the stack pointer (%esp) into the
target register, %ebx in this case.
The second line masks (AND) that register with -8192,
better understood as 0xFFFFFFE000 to clear the lower
13 bits.
Presumably, this macro is used to return the base
(lowest) address of the current stack. It isn't very
general code because it assumes that the stack size
is an invarient 8 KB.

Subject: init_module in linux 2.4.x
Date: Mon, 30 Apr 2001 05:06:49 +0900
I'm a beginner of Linux and I'm just starting to read USB source code
in Linux 2.4.3. I cannot find "init_module" in USB source code, but
the USB seems to be linked dynamically with insmod.
Could anyone show me why it's not in the source code, and process
of USB core installation/initialization and OHCI installation/initialization
?
I guess usb_major_init() is the top level of initialization part for USB
core
which calls devfs_register_chrdev(), the same function as
register_chrdev().
I'm not sure the process "where from" and "when" the usb_major_init()
is called.
I guess init_module() for usbcore is called when insmod links usbcore.o,
but
I haven't found the init_module() in the USB source code.
What is the process from insmod to usb_major_init ?
Thanks,
Pirates

OK, that sounds great. If I upgrade to gcc-2.95.3, will I still be able
to build kernels for RH 6.2 ? Will I need to upgrade any system
libraries ? How easy will it be to revert to my old compiler if I run
into problems ?

It's OK, I'll steer clear of going to 7.x for now.

Or install gcc-2.95.3 which has ostringstream in its version
of the STL.

Indeed. With gcc-2.95.3 the STL support is pretty complete. gcc-3.0
should finish off all the corner cases in the c++ support hopefully.
