I developed a kernel module and some functions on it. Now i need to develop a program in the user space and call some functions which are in the kernel module.
I also need to access some global variable that are in the kernel module on my program at the user space.
I want to build a kernel module that will be compatible with all the kernel’s releases.For example, if I build a kernel module on kernel 3.2.0-29 and try to load it on 3.2.0-86, I get the following error:
modprobe my_driver
FATAL: Error inserting my_driver (/lib/modules/3.2.0-86-generic/kernel/fs/my_drv/my_drv.ko): Invalid module format
[ In the log messeges: my_drv: disagrees about version of symbol module_layout ]
How can I build a kernel module on 3.2.0-29 that will be good for all 3.2.0 releases.
I am trying to develop a kernel module that hooks the READ system call. for some reason it just doesn't recognize that function.
I saw another question of this sort but I didn't really understand the answer or what to do.
I am working on Kali 4.19.93 with Raspberry-pi 4
My code:
#include <linux/module.h>#include <linux/kernel.h>#include <linux/init.h>#include <linux/moduleparam.h>#include <linux/syscalls.h>#include <linux/slab.h>#include <linux/kern_levels.h>#include <asm/unistd.h>#include <asm/cacheflush.h>#include <linux/semaphore.h>#include <asm/set_memory.h>MODULE_LICENSE("GPL");MODULE_AUTHOR("Omri Ben David");MODULE_DESCRIPTION("Hooking Linux System calls");MODULE_VERSION("1.0");unsigned long** SYS_CALL_TABLE = (unsigned long**) 0xc02011c4;asmlinkage ssize_t (*original_read) (int fd, char *buf, size_t count);asmlinkage ssize_t HookRead(unsigned int fd, char * buf, size_t count){ printk(KERN_INFO "Rootkit_Debug: Yay you entered my function!!\n Now you can read\n"); return (*original_read)(fd,buf,count);} static int __init SetHooks(void){ printk(KERN_INFO "Hooks Will now be set, hold on tight\n"); printk(KERN_INFO "System calls table is at address %p\n",SYS_CALL_TABLE); original_read = (void*) SYS_CALL_TABLE[__NR_read]; set_memory_rw((long unsigned int)SYS_CALL_TABLE,1); SYS_CALL_TABLE[__NR_read] = (unsigned long*)HookRead; printk(KERN_INFO "System calls hooked successfully\n"); return 0;}static void __exit HookCleanup(void){ printk(KERN_INFO "System calls restore innitiated\n"); SYS_CALL_TABLE[__NR_read] = (unsigned long*) original_read; printk(KERN_INFO "System successfully restored. hope you had fun");}module_init(SetHooks);module_exit(HookCleanup);So I'm playing around with reading system registers in the kernel and I've recently run into a bit of a roadblock.
In ARM64, certain system registers (e.g. OSECCR_EL1) are not always implemented. If they are implemented, then trying an mrs instruction is fine - nothing bad happens. But if they AREN'T implemented, then the kernel throws an Oops due to an undefined instruction.
This isn't unreasonable, however, as I'm inside a kernel module while running this mrs instruction, I don't see an easy way to recover from this oops, or even recognize that a particular system register read was going to fail in the first place.
Is there any easy way to identify beforehand whether a system register is valid, or at the very least, handle a kernel oops in a way that doesn't immediately stop my kernel module function execution?
I am trying to add appArrmor to my img.
This is the .config file that my device use.
I have add CONFIG_SECURITY_APPARMOR=yCONFIG_SECURITY_APPARMOR_HASH=yCONFIG_SECURITY_APPARMOR_HASH_DEFAULT=yCONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE=1 but sudo apparmor_status still returnapparmor module is not loaded.
I have too questions
The OSDev wiki says that:
It is traditional and generally good to have your kernel mapped in every user process
Why is that though? Can't the process be mapped to memory solely? What are the advantages of mapping the kernel and wouldn't that be a waste of space?
Also, is it possible to access the kernel space from the user space and why would I do that?
I have an embedded ARM system with processor AT91SAM9G45. I try to build linux kernel with initramfs for this system. Kernel version is 4.14.79.
After loading kernel and initramfs image at device I have following:
Kernel definitely finds out initramfs image, unpacks it and sets it into memory.
Kernel definityle finds all files in initramfs image, I see it in debug messages I've added into linux kernel source code.
After unpacking initramfs image kernel tries to start /init process. /init processes starts and instantly returns 0 (0 means no errors) and then instantly throws kernel panic message:
Freeing unused kernel memory: 384K
This architecture does not have kernel memory protection.
run_init_process BEFORE /init
run_init_process AFTER /init, result = 0
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004
"run_init_process_BEFORE /init" and "run_init_process /init, result = 0" are debug messages that I've added to linux source code.
Initramfs image is build by using busybox.
There is no difference, what an initial script or executable file I try to start. Results are same. If /init script tries to echo some message and sleep for some seconds, kernel does not show message and does not wait, and throws panic message instantly.
So I compiled statically this simple program and tried to start it:
#include <stdio.h>int main(int argc, char *argv){ printf("Hello world!\n"); sleep(999999999);}Same result, with no "Hello world!" and with no sleeping:
Freeing unused kernel memory: 384K
This architecture does not have kernel memory protection.
run_init_process BEFORE /hello
run_init_process AFTER /hello, result = 0
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004
If I compile this program with x86_64 gcc compiler, result is -8:
Same result, with no "Hello world!" and sleeping:
Freeing unused kernel memory: 384K
This architecture does not have kernel memory protection.
run_init_process BEFORE /hello
run_init_process AFTER /hello, result = -8
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004
So it means that linux kernel defines whether the file is executable at current platform.
If I compile hello.c program with no static linking, result is -2 (and kernel panic message after this). If I put .so files into initramfs image at the /lib folder, result is 0, and kernel panic message after this. If I put .so files that are compiled with x86_64 compiler, result is -13, and kernel panic message after this.
So what's the reason of this message? I cannot find it out.

The mtd flash of the device is already being used by the u-boot and linux but how can I use the same solid state storage/flash with utility functions of cvmx-flash.c in bare metal simple executive firmware of Cavium Octeon for the said purpose (i.e dumping crash)? How octeon simple executive firmware can read/write the solid state storage/flash that is already successfully accessible by linux & uboot?
I was learning basics on checking fTPM 2.0 on my device. I was following the basics mentioned here :https://github.com/vchatterji/tpm2-luks

I know to disable it by compile a kernel without setting CONFIG_DRM_VMWGFX in config.But I don't want build a new kernel,can I achieve it by some configuration?
I tried to delete vmwgfx.ko from the lib/modules/.../kernel/driver directory and reboot,but the driver works well On Ubuntu 16.04.Why?Is the file elsewhere?
And I also tried to rmmod,but it's not work.

I am using system call interception with kprobes. The idea is this: before calling unlink, I intentionally open the file and write zeros into it. However, I get a problem that kprobes hooks cannot "sleep" and calling kernel_write() breaks the kernel. What could be the solutions to my problem? Maybe there is a variation of the kernel_write function without asynchronous writing?
I just want to know the difference between System.map file and /proc/kallsyms.
I am using Linux 3.16 generic kernel. I know that both are the kernel symbol table.. When I did a compare on this files, both are having the same content.
So what is the need of having both?
So my Samsung Ativ Book 8 laptop has a Radeon 8770m and the integrated HdD4000 built into the intel i7-3635QM Processor. It looks like the HD4000 has some kind of hardware failure. Anytime I boot the computer, it just dies as it's going into Ubuntu. This happened on Windows too, so I switched to Linux to see if I could have more control. Also, the bios doesn't allow disabling of the HD4000.
The only way the laptop works while having proper intel and amd drivers is if I have an external monitor plugged in. If it shows the llvmpipe drivers, then the laptop works fine, but the external display doesn't work. Also I think the radeon gpu is disabled too.
My hope is to just completely disable the HD4000, maybe kernal level? Let everything run on the AMD 8770m. I'm okay with using my laptop basically as a desktop. It's old and the battery is trash anyways. Thank you for your help.
I own a keyboard that has an anti-ghosting mode.
It is toggled on/off using Fn+ScrollLock. When on, the codes sent are a bit different. The keyboard is still legitimate HID, but, for example, all modifier keys are seen by Linux as Shift and the actual modifier key is in another field of the event.
What I am looking for is either a ready driver (should someone happen to know about one) or some introduction to writing such input drivers. I do not know much about the ecosystem (evdev, libinput, etc.) and I do not even know where to start. If possible, the same driver should work both under X11 and under Wayland.
Just for the record, the keyboard's “shop” name is Modecom Volcano Gaming. The USB ID is258a:1006 and it is apparently not annotated in usb.ids. The keyboard works perfectly fine in both modes under Windows.
I'm using Lorax-Composer to try and build a custom RHEL 8.1 image for upload to amazon AWS. For testing I am using a generic image built with Lorax and just a baseos install.
I've followed the directions at the RHEL user portal without incident. I've also created a local repo mirror following the weldr instructions page, since lorax-composer can't read from the online repos. No issues.
I log into the cockpit gui, select the "stock" example development server, and the logs don't kick off any errors. I follow the RHEL directions to upload, convert to a snapshot, create an ami, and launch the instance (m5.xlarge resoruce to make sure there are no resource constraints) and... nothing. The instance goes to "running", but status checks never pass and the instance is non-responsive. Security groups allow all connections from 0/anyport and the instance won't answer pings or accept an ssh traffic. After about 5 mintues I can see the instance reboot. There are not monitoring logs or dumps from aws regarding the instance, everything is blank (and it looks like the cpu isn't even initalized, all the monitoring graphs are blank).
I've opened up aws rhel golden images from the aws marketplace using my dev account, but the goal is to be able to upload a custom image of the RHEL8 kernel. I did notice that RHEL8 golden images only go to 8.0, so I'm wondering if there's an issue packaging the 8.1 kernel? In order to use a RHEL8 golden image I have to use their ami to boot into 8.0 and then upgrade the kernel using Yum. I also tried using weldr to package the vm as a .vmdk and a .img and run the same conversion process, to see if it was an issue with the .ami kickstart script, but results are identical. I'm thinking it has to be an issue with the 8.1 build that lorax-composer is generating. Is there a way to force the 8.0 kernel to build out of the repo? I thought about pulling the rhel7.x repos but, even if that successfully created an ami I could use, it woudln't be much use as the point is to run rhel8 on aws with a custom image.
I've tried looking for how to package my own copy of 8.0, but I don't think the 8.0 Kernel is in the current RHEL developer's library. Does anyone have any ideas or experience dealing with custom ami image imports? I've attached the logs from the lorax-compsoer below, as theya re the only logs I have for this process...
I would also be open to using another .ami builder if anyone has had success with a different software package than lorax-composer to get custom rhel8 into aws.

I have recently made my usb bootable and have burnt kali linux os on it.The boot is working pretty fine but I want wifi access since I'm using a laptop.Searched alot on youtube and google but didn't find anything.
Can anyone solve my query by providing step wise solution on how to access wifi in this scenario??
I am attempting to make a system call that takes the filename as input and edits a tag that I will place the file struct . However, I cannot figure out how to find the file from the filename (it is required to do it this way for my class). I figure there is a syscall or function that exists to do it, but I am having trouble finding it.
