  • c25a785d6   score: fix off-by-one index into syscall table ... Browse Code »

    If the provided system call number is equal to __NR_syscalls, the
    current check will pass and a function pointer just after the system
    call table may be called, since sys_call_table is an array with total
    size __NR_syscalls.

    Whether or not this is a security bug depends on what the compiler puts
    immediately after the system call table. It's likely that this won't do
    anything bad because there is an additional NULL check on the syscall
    entry, but if there happens to be a non-NULL value immediately after the
    system call table, this may result in local privilege escalation.

  • f673c032e   score: add generic sys_call_table ... Browse Code »

    This adds back a sys_call_table to the score architecture, which
    got lost in the conversion to the generic unistd.h file.
    It's rather worrying that the code got submitted without a
    system call table, which evidently means that it got zero
    testing.

    Since the system call table has a different layout from the old
    one (which was modeled after the mips-o32 one), I also try to
    fix the entry.S path to use it. In the modified calling conventions,
    all system call arguments are passed as registers r4 through r9,
    instead of r4 through r7 plus stack for the fifth and sixth argument.

    This matches what other architectures to when they normally pass
    arguments on the stack.
