Hi there,
Does anyone know if there's support for IP over IEEE1394 in the new kernel?
If not, does anyone know who's working on it and if they can use newbie
help?
Thanks,

I am not aware of a more relevant newsgroup to ask, so here gos:
I need a script(, command, utility, etc) to produce a list of files
contained in a CVS repository and their version numbers for a specific
release tag. Can anyone point me in the right direction ? I know I
could write a script to repetitive call 'cvs log' and parse out the
relevant information but surely this has been done before?
example:
File.c: 1.3
File2.c: 1.4

.
Thanks in Advance,

Hi, Guys.. Last night, I installed Kernel 2.4 on my linux machine..
And I compiled it and rebooted.
When the prompt, "%", was displayed, and I typed startx..
Then X windows was up. But I could not type any character and move mouse.
Who can help me to work it properly.... ?
I think that the system is still on, because I can login into the system and

Well, as I mentioned later in the article you snipped, Plan 9 seems to
apply this same philosophy to kernel API's.

Obviously I have argued no such thing about *any* binary API /
protocol. I've merely observed that /proc on Linux et al. "textual"
kernel interfaces have their merits.

Hi,
Where can I find a detailed document about the IPv6 is implementated on
Linux ?
I am particularly interested in the data structures used for routing and
forwarding tables. I had a brief look at some linux code and found out
that for IPv4 they used a hash table and for IPv6 some sort of tree
structure but could not figure out the details.
If somebody could elaborate especially on the forwarding tables, it
would be great!
Thank you.

linux2.2.17/arch/i386/boot/setup.S line #522
I think the code from "move_self_1" to "end_move_self" will move
CS-DELTA_INITSEG:0 to INITSEG:0 (total "setup_move_size" bytes).
Why take the trouble to do this in two steps, by moving the code above
"move_self_here" first, then the code below it?
Tom Wang
P.S. the following is what i think it want to do:
if (CS!=SETUPSEG) {
cli; // disable interrupts
// store new SS in DX
DX = SS;
AX = CS - DELTA_INITSEG;
if (DX>=AX) {
DX = DX + INITSEG - AX; // i.e. SS-CS+SETUPSEG
}
// move CS-DELTA_INITSEG:0 to INITSEG:0 (setup_move_size
bytes)
--> // TODO: why not do this in one step?
ES = INITSEG;
move _DOWNWARD_ from CS-DELTA_INITSEG:setup_move_size-1 to
(INITSEG:setup_move_size-1
... INITSEG:move_self_here+0x200);
// move setup_move_size-move_self_here-0x200 bytes
// INITSEG:move_self_here+0x200 = SETUPSEG:move_self_here
goto SETUPSEG:move_self_here;
move_self_here:
move the rest to INITSEG:move_self_here+0x200-1 ...
INITSEG:0;
// move move_self_here+0x200 bytes
DS = SETUPSEG;
SS = DX;
}

I too need such an "adapter device" via which I can RESET the
SCSI BUS.
BTW, any clue as to how can I RESET the SCSI BUS for the device
that I have opened ? i.e. via the /dev/sdxx interfaces
I found no ioctl defined for resetting the SCSI BUS.
I was thinking of extracting the "sg" (generic SCSI) device code
and wrap it as an adapter device by adding the required functionality.
Any comments ?

Did you install devfs? If so, either read
/usr/src/linux/Documentation/filesystems/devfs/README or don't use devfs.
Specifically the part in the README that mentions a certain daemon that you
*must* install first.

Yes it is posible, but it is not a good idea. In fact it
is a very bad idea, and if you do sooner or later it will
give you lots of trouble.
The symbol table in entry.S has entries numbered from 0
to NR_syscalls, there are unused entries pointing to
sys_ni_syscall(). You could change one of theese to point
to your syscall, but if another module or another kernel
uses the same syscall you start geting trouble. Try
considering what could happen if a syscall does something
completely different from what the program expect, the
program might not even notice because it assumes ENOSYS
in case of missing syscall. Assigning some very large
number does not work either because the syscall table
would need to be expanded to a huge size.
Using an unused entry in the syscall table is OK for your
own testing purposes, but before releasing a module using
this sycall you must convince Linus that he should assign
you an official syscall number.
