Programming :: Write A Module In Pure Assembler?

Jan 16, 2010

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 ?

Programming :: An Assembler Directive To Interpret All Constants In Hexa?

Jul 9, 2011

GNU 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:


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).

Programming :: GCC Inline Assembler Doesn't Even Support Local Variable?

Jul 3, 2010

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]

Ubuntu Installation :: Remove Pure-ftpd Pure Admin - Getting A 530 Authentication Error

Mar 24, 2011

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


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?

Software :: Pure-authd Not Passing Variables To Pure-ftpd

Feb 9, 2011

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.

Programming :: Cannot Edit B800:0000 In Pure Dos

Nov 11, 2010

I write the below sample program named "h1.asm"?


assume cs:code
code segment
mov ax,0B800H


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, 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.


"Welcome to dosemu!"
D:masm>debug h1.exe
AX=0000 BX=0000 CX=000F DX=0000 SP=0000 BP=0000 SI=0000 DI=0000


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.

Security :: SELinux Module To Allow Snmpd To Write To /tmp?

Aug 11, 2010

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:

type=AVC msg=audit(1281516573.123:18422): avc: denied { write } for pid=6933 comm="" name="tmp" dev=dm-0 ino=1474561 scontext=root:system_r:snmpd_t:s0 tcontext=system_u:object_r:tmp_t:s0 tclass=dir

General :: Write Kernel Module That Will DMA Custom Card?

Aug 31, 2010

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?

Programming :: Use MPI Only In A Module Of A Given Sequential Program?

Jun 28, 2011

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?

Debian Programming :: Building Kernel Module

Dec 8, 2013

I'm trying to build the kernel module for dvbhdhomerun. The problem is the linux kernel headers provided by Debian do not have the dvb header files. Trying to set up my own kernel source tree to use is not working out so well.

I'm following the instructions in the Debian section here: [URL] ....

My first try compiled, but the modules ender up under /lib/modules/3.2.51/extra instead of /lib/modules/3.2.0-4-amd64/extra. Why?

I tried to start over, but noticed this while running apt-get source linux-image-3.2.0-4-amd64:

Code: Select allReading package lists... Done
Building dependency tree       
Reading state information... Done
Picking 'linux' as source package instead of 'linux-image-3.2.0-4-amd64'
NOTICE: 'linux' packaging is maintained in the 'Svn' version control system at:

[Code] ....

The failure to verify the signature has me concerned, but beyond that, what do I do about the different version number when compiling and installing the kernel modules?

Programming :: Compiling Kernel Module Using (/asm/system.h)

Apr 3, 2011

I`m trying to compile sources of kernel module which has been written for kernel 2.6.9. There were many changes in kernel headers since then in current kernel sources. I`ve found that old /asm/system.h was moved under architecture dedicated directory /arch/*/include/asm/system.h. Anyway during sources compilation I`m having errors related to kernel sources. It looks like there is something wrong with this /asm/system.h


../asm/system.h: In function �__cmpxchg�:
../asm/system.h:248: error: expected string literal before �LOCK_PREFIX�
../asm/system.h:254: error: expected string literal before �LOCK_PREFIX�

We are working on a project where we need to modify this file. Compiling every time we change something will be time consuming. Is it possible to compile just this file and insert it as a normal module?
