I need to write a module in pure assembler.Now the linker needs symbols out of the kernel library to link to ( module_init, module_exit, printk).Does anybody know the kernel library name, or are these symbols only in the compressed kernel image (vmlinuz) ?And if, how can I link to a compressed kernel image ?

View 2 Replies View RelatedGNU assembler 2.17 And without having to prefix them. I'm skimming through as info page and can't find any pseudo operator or assembler directive of this type. E.g. 74 would be a decimal number. But I want it to be hexa 74 without the need to write 0x74.
NOTE: as is the GNU assembler.
EDIT: Google led me to discover this:
Quote:
If you write numbers without an explicit indication of the base, the most recent `.RADIX S' command determines how they are interpreted. However, on the one hand, it says the most recent and, on the other one, it applies to GASP, the GNU assembler preprocessor. IDK if it is the same as as (the GNU assembler).
It's good that GCC support intel inline disassembly syntax, but it cannot even simply address local variables/parameters properly, making itself stupid and essentially useless, look at the following:
int myfunc(float f){
int x;
float fa[8];
asm(".intel_syntax noprefix
"
"mov eax, [x]

I am trying to learn assembly using nasm as assembler. I did not found example related to string operation. I had following example code,
global asm_strlen
section .data
section .bss
section .text

my problem is at highlighted line, I am not getting how to copy a byte into 4 byte reg. rather what is syntax of mov instruction to mov byte to WORD DWORD etc.
I am having problems troubleshooting my pure-ftpd setup. I am always getting a 530 authentication error. I attempted to correct the problem by doing the following:
# pure-pw mkdb
# ln -s /etc/pure-ftpd/conf/PureDB /etc/pure-ftpd/auth/PureDB
# gedit /etc/pure-ftpd/conf/PAMAuthentication
[code]....
This create a new error. 421 Unable to read the indexed puredb file (or old format detected) - Try pure-pw mkdb I am getting a feeling this is getting from bad to worse. I attempted to remove pure-ftpd and pureadmin to start over again. However, it appears I cannot remove everything. I attempted the following:
apt-get remove pure-ftpd pureadmin I am not sure what this really does because I can still see the folder /etc/pure-ftpd and I cannot remove it. I could not use rm /etc/pure-ftpd because the system said it was not empty. I also tried sudo aptitude remove pure-ftpd pureadmin . Again I cannot completely remove the folder. How do I completely remove pure-ftpd and pure admin and all databases, files and folders so I have a fresh system ready to start the install again?
I have set up pure-authd and pure-ftpd. They are both running, I have created the socket etc.
In my authentication module (a php script) for testing purposes I have done a vardump in to a file, and have realised that pure-authd is not passing on any variables (username, password of the current person trying to log in via ftp) to the PHP script.
I am sure the authentication module is working (have tested it vigorously on the command line), but after 10 hours wondering why it wouldnt work and messing about with the script, I have realised that the variables were never even getting in to the script in the first place!
I am running the processes such as this:
Everything seems as if it is working other than this. For instance, when testing the setup with a very basic auth module which doesnt require a username or password (the basic module just passes "auth_ok:1" to pure-ftpd and the user is then logged in), I can log in to the FTP server fine.
But like I say, a vardump ($argv) on my proper PHP authentication script would suggest that no username or password are being passed to it.
I write the below sample program named "h1.asm"?
Code:
assume cs:code
code segment
mov ax,0B800H
[code]...
1. In Windows platform +MASM 5.0, run "command" and use "debug.exe" to see what would happen. As step by step check, I see B800:000 is not modified as expected.
2. In Ubuntu 10.04 + dosemu 1.4.0.1, run the program in two ways:
a. If exec dosemu in command line as "$dosemu -dumb", yes, it's in shell mode. and then use debug to check, "B800:0000" can be modified as expected.
Code:
"Welcome to dosemu 1.4.0.1!"
D:masm>debug h1.exe
-r
AX=0000 BX=0000 CX=000F DX=0000 SP=0000 BP=0000 SI=0000 DI=0000
[code]....
b. If exec dosemu in command line as "$dosemu", and run the program again, the symptom is as same as 1.(pls see attachment picture).
3. In Windows, I replace "mov ax,0B800H" to "mov ax,2000H" and try again, it would be edited well. So I wonder if it is coursed by "B800" segment address.
I am using the "extend" function of snmpd to run a script in order to extend a monitoring platform. This script being ran by snmpd needs to write to a file in /tmp for later parsing, but SELinux is stopping it from writing to the file under /tmp. The following two lines from my audit.log file show what is happening:
Code:

I am trying to write a kernel module that will DMA my custom card. Right now when i plug the card into linux no valid PCI device shows up (meaning I probably have a error on my end, i know) however, If I halt the system at startup in the bootloader (uboot) I am able to directly access the card as I know in uboot the physical memory address that is mapped to my device. Is there a way I can access the card in a simliar fashion in linux?

I am looking for a assembler, in my college there is a ia32build assembler. I have tried searching it in Google, but I can't find it. I have x86 processor and I want to install it in Ubuntu 10.4.

Edit 2 : The syntax is quite different from nasm. Here's my sample code.

can one use MPI only in a module of a given sequential program? That is, if one have an already working sequential program, can one append to it a MPI-based module? Say I have a working main. It calls module() and what this module does is to spread a group of processes to accomplish a given task. Can that be done or the entire original sequential program must be rewritten?
