hi,
as u can guess, i'm a kernel n00b....

basically we already hv code developed in userspace, now we want to move to kernel space..... but i'm a lazy usersapce developer and hv used a lot of libraries... like openssl, flex, regex
so my question is,
1. is there any way to attach these libs to lkm.... or how should i go about it....
2. much of my stuff is in c++... so can i link libstdc++ (i know this is an invitation to flames.... and it is absolutely bad idea to hv c++ code in lkm... but let me know is there any possibility to hv it in kernel??)
3. and is there any limitation on the memory we can use in lkm... i mean i might use kmalloc number of times.... or other way is it possible to pass data structure from userspace to kernel space??

plz bare with my lack of knowledge.....
TIA

Wow, your best bet is to write a simple shim kernel module and leave the bulk of your program in userspace, porting that into kernel space would be a nightmare.

i completely agree with u.... but for me nightmare has come true..

.... using userspace libs in kernel... does not make any sense.. they actually use kernel to complete their task... and i really made the partitioning such that the lib dependent code will reside in userspace ... but my superiors r keen on hving all the things inside the kernel

and the current timeline certainly don't allow me to hack these lib src to implement my own.... i would certainly see this as an option in longer term...

TIA

Good Luck. Have fun. Don't go crazy.
