Actually this has already been tracked down. It seems that if you call a system call in UML which is in the range of acceptable system calls and which has not been set to sys_ni_syscall then it will give that result. The interim solution is to set any unimplemented system calls that your programs will call (223 for me) to sys_ni_syscall. But this still means that it will be common for UML kernels to have some sys-calls which applications can call to crash them (not good for honey-pot machines). -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ User-mode-linux-devel mailing list User-mode-linux-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-devel
