Since all users of this have now been eliminated, we can eliminate the element itself. MMC host drivers now operate only on the scatter lists passed to them, rather than needing knowledge of block devices. Signed-off-by: -

Before Bodo's signal fixes and my signal delivery rework, it was possible for a process to execute UML code by running the default signal restorer. This is no longer possible, so this check can be removed from the sanity test for UML accidentally tracing itself. Signed-off-by:

This implements using the new ptrace option SYSEMU_SINGLESTEP in UML (advanced sysemu) in SKAS and TT modes. To have a fast selection of the appropriate ptrace option to use next, a 2 dimensional arry is used and singlestepping() is modified to return 0,1 or 2: 0 = don't do singlestepping 1 = singlestep a syscall 2 = singlestep a "non syscall" instruction In do_syscall() writing of the syscall number is supressed, if the advanced sysemu is in use (that does it itself).

From: Bodo Stroesser <bstroesser@fujitsu-siemens.com> My older patch, that sets TIF_SIGPENDING after an ptrace-interception in syscall_trace() is wrong. Some syscalls want to be called without any signal pending. If a signal is pending on syscall-entry, they immediately return with -ERESTARTNOINTR. Thus, on return to user, the pending signals can be processed and the kernel will lower eip by 2 to have the syscall restarted after that. Since my change sets TIF_SIGPENDING on the entry and exit interception, stracing such a syscall looped! Try "strace ls" to see what happens. Fix: set TIF_SIGPENDING on the exit interception only. This avoids the loop and is enough for security. Signed-off-by:

From: Bodo Stroesser The implementation of sys_sigreturn() and sys_rt_sigreturn() in UML must be changed. This is necessary, since the return value of sys_*_sigreturn() is the value of eax in the thread, that was interrupted by the signal handler. If accidentaly eax contains -ERESTART_*, orig_eax *must* be -1 to avoid syscall restart processing in kern_do_signal(). If orig_eax is >=0, eip might be lowered by 2, the process will fail. In UML PT_REGS_SYSCALL_NR() or UPT_SYSCALL_NR() have to be used instead of orig_eax. While writing and testing an exploit for this, I saw that for most interrupts, the syscall number is undefined. So even on a return from interrupt a wrong syscall restart handling could happen. And also: UML resumes a process with ptrace(PTRACE_SYSCALL/SYSEMU/SINGLESTEP when a syscall in UML in SKAS mode has been processed. But since there is a valid syscall number in the host's orig_eax, the host could do a wrong syscall restarting if the syscall in UML was a sigreturn() returning -ERESTART* To avoid this, in SKAS -1 should be written to regs.orig_eax before restore_registers().
