| |
In ia32 emulation, the amd64 kernel refuses the ioctls TIOCSBRK and TIOCCBRK with EINVAL. I've attached a patch that adds them to the compatibility list.
Since all architectures have these ioctls ("m68knommu" inherits them from "m68k", "um" from its host) and use the same code, I think adding them to compat_ioctl.h is the correct choice (as opposed to adding them to arch/x86_64/ia32/ia32_ioctl.c).
The patch is for 2.6.9. I've observed the problem the first time in 2.6.7.
