Hello all, I'm doing the porting of uClinux to a new architecture and I have a problem with the sys_close system call. Indeed, init process open a first time bin/sh to read and execute the commands of etc/rc. When sh terminates, the filp_close() function resets the 'next' field of the console filp. The problem is when bin/sh is re-opened to show the shell prompt, the system does an endless loop into check_tty_count() (driver/char/tty_io.c) because the filp->next filp is 0 instead of list head. It seems that something is not updated in a structure somewhere but, I really don't understand what. The problem is I'm stuck for several days because of this disfunctionnement. So perhaps someone have already seen a similar problem or have an idea which could help me? It will be difficult for you to bring a solution in these circumstances, but perhaps you could points me to a way that I haven't explored. Thanks in advance for your help. Regards.
