Hello all, In kernels 3.X up to 4.2 execve(|) system call was for x86_64 architecture the the system call was made through some magic ( I can't say I understand it ) assembly stub in arch/x86/kernel/entry_64.S so up to kernel 4.2 it was possble to patch this assembly to install the hook, ex. see http://stackoverflow.com/questions/8372912/hooking-sys-execve-on-linux-3-x/9672512#9672512
But this hook still can't access in a proper way filename argument, althouth I tried to do it with in the same way as fs/exec.c does : using kernel's getname() function (which I was need to find through kallsyms_lookup_name() In kernels 4.2 and up, the arch/x86/kernel/entry_64.S is gone, and I still dont' have a clue what to do to get filename as a char string. Please advise. Lev. _______________________________________________ Kernelnewbies mailing list [email protected] https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
