Hi, does this affect us, in particular with my changes to set_state? I am not even sure which tcsetattr implementation in glibc we use (the bsd one?).

Hi, I got a bug report about glibc/struct termios on PPC. Since the struct termios is different between glibc and kernel, we copy the structre. On PPC, we call tc[gs]ettattr for this. But this functions do some extra checks and return with an error, if the kernel does not accept CSIZE, PARENB and CREAD. Some programs like xterm makes TCSETS-ioctls (and don't call tcsetattr), but we call tcsetattr which fails and return a wrong error code to the caller. POSIX says: The tcsetattr() function shall return successfully if it was able to perform any of the requested actions, even if some of the requested actions could not be performed. so the wrapper in the current implementation is not correct. How can we fix this? One suggestion is to add an internal flag so that our tcsetattr does not perform the check, the other is to remove or fix the wrapper.
