root privaleges, I'm just trying execute script, tv hang, propably i'm doing something wrong with execl.
On CI+ you can't run no signed software, CI doesn't have sign check code I think authd do that on CI+.
Each executable(*.so) file has *.mac with 16 bit sign.

16 bit? Fighting with 16bit sign (65536 probabilities) algorithm is more easier that trying to solve 256 bit AES puzzle
Might be exhausted for who want to try all keys, but I think we can guess right keys from example CI+ tools, Can't we?
Do you know where is example CI+ applications available for download? Needed to look at them.

ups, sorry I was mean 16 bytes.
Btw execl, it seems it doesn't hang tv, telnetd still works. it seems, it doesn't return from execl, or something diffrent happen, and watchdog restart after few seconds.

have you tried to write to /mtd_rwarea/ ? may we are sandboxed into the game directory?
thnx a lot for the code.

strange thing, app won't write to usb (test file should appears in setup directory?)
but write to /dev/kmsg is ok (test output with dmesg).

Yes, it should write to Setup dir, make sure write access is ok.

i guess exec calls wont work due not existent /dev/tty
a simple
will be executed without reboot and sample lib exits clean.
happy hacking

I wonder if start telnetd will work.
If it's indeed lack of tty, it seems mount load modules need implemented into library instead execute scripts.
However I didn't tried yet load module or mount nfs/smb.

I just tried this and works
system("/etc/telnetd_start.sh");
system("insmod /dtv/usb/sda1/modules/cifs.ko");
no need patched firmware
