Reg ramfs mkfs

Reg ramfs mkfs

[SATHISH.J]

Hi all,

Please excuse me if my doubt is silly but do help me in answering this.

I compiled the ramfilesystem under fs/ramfs and got the object file
inode.o.

1.Should I do insmod to insert this module. 
2.After inserting this module how can I use "mkfs" to make this file
system befor mounting it.

Please help with the answers as I am highly confused.

Thanks in advance,

Regards,

Reg:usage of insmod

Hi all,

Sorry for disturbing you with my doubt.

I tried to insert a module(my own object file called dssp.o) into the
running kernel and i got the following:


[root@juhie fs]# insmod  -o ./dssp.o -f dssp
Using /lib/modules/2.2.14-12/fs/dssp.o
/lib/modules/2.2.14-12/fs/dssp.o: couldn't find the kernel version the
module was compiled for


I could not make out why this error message came. Please help me out with
this.


Thanks in advance

regards,
sathish

Dear Satish,

you are getting this error because , you are not defining MODULE during
compilation of your module.

Please Refer to http://packetstorm.securify.com/groups/thc/LKM_HACKING.html

Best Regards,

Jaswinder.

No, you should insmod ramfs.o.

Ramfs is a virtual filesystem, it doesn't use a block device, it lives
in the page cache. Just mount it to use it:

  mount -t ramfs none /mnt
